We study whether monetary authorities in the G7 countries were changing their responses to inflation in a similar manner during and following the Great Inflation era. We find that the common to the G7 countries inflation pattern during the Great Inflation period could be associated with a common pattern in the monetary policy response to inflation: we find that until the early 1980s monetary authorities in the G7 countries responded mildly to inflation, systematically fought it throughout the 1980s and lessened again their response during the 2000s. The estimated Taylor rule coefficients on inflation are co-integrated, implying the existence of a long-run relationship in the responses to inflation during and after the Great Inflation period. At the same time, principal component analysis of the residuals of the estimated Taylor rules indicates that the shocks' structure cannot account enough for the monetary policies' co-movements. We interpret these findings as suggestive of common monetary policy patterns.

The literature has proposed two potential channels through which monetary policy played a role in the Great Inflation in the United States. One approach posits that the Federal Reserve held misperceptions of the economy. An alternative explanation contends that policy makers shifted preferences from an output gap stabilization goal toward inflation stabilization after 1979. This paper develops a medium-scale macroeconomic model that incorporates real-timelearningby policy makers as well as a (potential) shift in policy makers' preferences. The empirical results show that combining both views—distorted policy makers' beliefs about the persistence of inflation and the inflation-output gap trade-off, accompanied by a stronger preference for inflation stabilization after 1979—illuminates the role played by monetary policy in propagating and ending the Great Inflation.

The rate of inflation fell far less over the period 2007-2013 than in the period 1979-1985 despite similar large increases in the unemployment rate. This paper asks why. Possible explanations include a change in the persistence of inflation, changes in NAIRU, and other shocks. A change in the persistence of inflation, with inflation more anchored in the period 2007-2013 than in the period 1979-1985, is found to be important. The level and change in the NAIRU cannot be precisely estimated, but the data suggest an increase of nearly 1 percentage point since 2007.

Described by Mohr (2008:1) as "one of the most hotly debated economic issues in South Africa", the inflation rate is underpinned by its impact on the average South African. A rapid increase in the cost of goods and services could have devastating consequences on the both the growth and development of the country, making it an imperative to effectively manage a change in general prices. The SARB applies an Inflation Targeting (IT) framework to manage the inflation rate and the thesis will interrogate the applicability of this framework within a low growth environment. More specifically, the thesis will ask whether it is prudent to increase the interest rate in a low growth environment. The thesis will employ a mixed research method, namely, a qualitative and quantitative method. However, the qualitative method will be the primary research method and the conclusions derived thereof will be tested within a qualitative model. The qualitative method will take the form of historical narrative which is designed to investigate the behaviour of the inflation rate at a micro level. The choice of this qualitative historical narrative derives from the inconclusive nature of the existing empirical quantitative studies and the resulting lack of a consensus on the effectiveness of the IT framework. This lack of consensus necessitated the use of a different approach to interrogate the IT framework hence the application of the qualitative historical narrative. The narrative will be primarily derived from the economic reports and data of the main authority on South Africa's monetary policy, the South Africa Reserve Bank (SARB). The narrative will also utilise the economic reports and data from reputable sources such as Statistics South Africa, the International Monetary Fund (IMF), the World Bank, the European Central Bank (ECB), the US Federal Reserve System, and the People's Bank of China (PBC).

A study of recent inflation dynamics in the G-7, this paper discusses a problem with the Phillips curve which arose during the Great Recession (2008-2011). We find that work with time-varying slope, expectation anchoring, and core inflation can correct for the under-predictions that develop in the Phillips Curve during the recession, improving its accuracy throughout the G-7

Cette dissertation intitulé « Essays in the Political Economy of Inflation » est compris de trois papiers qui étudient le problème d'inflation d'une perspective politique-institutionnel. Tous les trois essais appliquent des outils techniques modernes de macroéconomie pour étudier des facteurs différents qui affectent le choix de politiques. Il est montré que ces facteurs sont cruciaux dans former la structure de gouvernance favorable pour l'efficacité de politique. L'environnement politique-économique complexe est difficile d'étudier avec les modèles traditionnels de politique économique fondée sur un projeteur social bienveillant qui maximise l'utilité d'un individu représentatif. Cette thèse, donc, approche l'économie politique d'inflation d'un côté pratique réaliste.Le premier essai a autorisé «Taxing the unobservable: The impact of shadow economy oninflation and taxes», est motivé par plusieurs études théoriques et empiriques qui se dispute que le taux d'inflation optimal augmente dans la taille de l'économie simple. Dans ce papier, nous construisons un petit modèle théorique qui a deux composants clés. Premièrement, il modèle explicitement le choix du gouvernement pour l'impôt de revenu ou inflation. Notre cadre est général et n'impose pas de la condition de la nature du gouvernement (i.e., il n'exige pas le gouvernement pour être nécessairement bienveillant ou corrompu). Deuxièmement, nous considérons explicitement l'économie l’informel (shadow economy) dans la fonction du gouvernement objectif. Il nous permet de voir comment il influe la charge fiscale et l'inflation. Notre modèle théorique indique un coût marginal croissant d'impôts et un taux croissant d'inflation dans l'économie d'ombre (shadow economy). Le principe de remplacement marginal rationalise le choix du gouvernement d'impôt d'inflation sur l'impôt sur le revenu
This dissertation titled “Essays in the Political Economy of Inflation” is comprised of three papers which study the problem of inflation from a political-institutional perspective. All the three essays apply modern technical tools of macroeconomics to study different factors that affect the choice of policies. It is shown that these factors are crucial in shaping the governance structure conducive for policy effectiveness. The complex political-economic environment is difficult to study with traditional models of economic policy based on a benevolent social planner maximizing the utility of a representative individual. This thesis, therefore, approaches the political economy of inflation from a realistic practical side. The first essay titled “Taxing the unobservable: The impact of shadow economy oninflation and taxes”, is motivated from several theoretical and empirical studies which argue that optimal inflation rate increases in the size of informal economy. In this paper, we construct a small theoretical model that has two key components. First, it explicitly models the government’s choice for income or inflation tax. Our framework is general and does not impose any condition about the nature of the government (i.e., it does not require government to be necessarily benevolent or corrupt). Secondly, we explicitly consider the shadow economy in the government’s objective function. It allows us to see how it impacts the tax burden and inflation. Our theoretical model indicates an increasing marginal cost of taxes and an increasing rate of inflation in the shadow economy. The principle of marginal substitution rationalizes the government’s choice of inflation tax over income tax

In this thesis I evaluate the departures of three common assumptions in macroeconomic modeling and estimation, namely the Rational Expectations (RE) hypothesis, the representative agent assumption and the use of first-order approximations in the estimation of dynamic stochastic general equilibrium (DSGE) models. In the first chapter I determine how the use of survey data on inflation expectations in the estimation of a model alters the evaluation of the RE assumption in comparison to an alternative assumption, namely learning. In chapter two, I use heterogeneous agent models to determine the relationship between income volatility and the demand for durable goods. In the third chapter I evaluate if the use of first-order approximations in the estimation of a model could affect the evaluation of the determinants of the Great Moderation.
En esta tesis analizo desvíos de tres supuestos comunes en la elaboración y estimación de modelos macroeconómicos. Estos supuestos son la Hipótesis de Expectativas Racionales (ER), el supuesto del Agente Representativo, y el uso de aproximaciones de primer orden en la estimación de los modelos de equilibrio general. En el primer capítulo determino como el empleo de datos de expectativas de inflación en la estimación de un modelo puede alterar la evaluación del supuesto de ER en comparación a un supuesto alternativo como learning. En el segundo capítulo, utilizo modelos de agentes heterogéneos para determinar la relación entre la volatilidad de los ingresos y la demanda de bienes durables. En el tercer capítulo, analizo si el uso de aproximaciones de primer orden afecta la evaluación de los determinantes de la Gran Moderación.

The thesis studies three distinct issues in monetary economics using a common dynamic general equilibrium approach under the assumptions of rational expectations and nominal price rigidity.
The first chapter deals with the so-called "liquidity trap" - an issue which was raised originally by Keynes in the aftermath of the Great Depression. Since the nominal interest rate cannot fall below zero, this limits the scope for expansionary monetary policy when the interest rate is near its lower bound. The chapter studies the conduct of monetary policy in such an environment in isolation from other possible stabilization tools (such as fiscal or exchange rate policy). In particular, a standard New Keynesian model economy with Calvo staggered price setting is simulated under various alternative monetary policy regimes, including optimal policy. The challenge lies in solving the (otherwise linear) stochastic sticky price model with an explicit occasionally binding non-negativity constraint on the nominal interest rate. This is achieved by parametrizing expectations and applying a global solution method known as "collocation". The results indicate that the dynamics and sometimes the unconditional means of the nominal rate, inflation and the output gap are strongly affected by uncertainty in the presence of the zero lower bound. Commitment to the optimal rule reduces unconditional welfare losses to around one-tenth of those achievable under discretionary policy, while constant price level targeting delivers losses which are only 60% larger than under the optimal rule. On the other hand, conditional on a strong deflationary shock, simple instrument rules perform substantially worse than the optimal policy even if the unconditional welfare loss from following such rules is not much affected by the zero lower bound per se.
The second thesis chapter (co-authored with Andrea Pescatori) studies the implications of imperfect competition in the oil market, and in particular the existence of a welfare-relevant trade-off between inflation and output gap volatility. In the standard New Keynesian model exogenous oil shocks do not generate any such tradeoff: under a strict inflation targeting policy, the output decline is exactly equal to the efficient output contraction in response to the shock. I propose an extension of the standard model in which the existence of a dominant oil supplier (such as OPEC) leads to inefficient fluctuations in the oil price markup, reflecting a dynamic distortion of the economy's production process. As a result, in the face of oil sector shocks, stabilizing inflation does not automatically stabilize the distance of output from first-best, and monetary policymakers face a tradeoff between the two goals. The model is also a step away from discussing the effects of exogenous oil price changes and towards analyzing the implications of the underlying shocks that cause the oil price to change in the first place. This is an advantage over the existing literature, which treats the macroeconomic effects and policy implications of oil price movements as if they were independent of the underlying source of disturbance. In contrast, the analysis in this chapter shows that conditional on the source of the shock, a central bank confronted with the same oil price change may find it desirable to either raise or lower the interest rate in order to improve welfare.
The third thesis chapter (co-authored with Andrea Pescatori) studies the extent to which the rise in US macroeconomic stability since the mid-1980s can be accounted for by changes in oil shocks and the oil share in GDP. This is done by estimating with Bayesian methods the model developed in the second chapter over two samples - before and after 1984 - and conducting counterfactual simulations. In doing so we nest two other popular explanations for the so-called "Great Moderation": (1) smaller (non-oil) shocks; and (2) better monetary policy. We find that the reduced oil share can account for around one third of the inflation moderation, and about 13% of the GDP growth moderation. At the same time smaller oil shocks can explain approximately 7% of GDP growth moderation and 11% of the inflation moderation. Thus, the oil share and oil shocks have played a non-trivial role in the moderation, especially of inflation, even if the bulk of the volatility reduction of output growth and inflation is attributed to smaller non-oil shocks and better monetary policy, respectively.
La tesis estudia tres problemas distintos de macroeconomía monetaria utilizando como marco común el equilibrio general dinámico bajo expectativas racionales y con rigidez nominal de los precios.
El primer capítulo trata el problema de la "trampa de liquidez" - un tema planteado primero por Keynes después de la Gran Depresión de 1929. El hecho de que el tipo de interés nominal no pueda ser negativo limita la posibilidad de llevar una política monetaria expansiva cuando el tipo de interés se acerca a cero. El capítulo estudia la conducta de la política monetaria en este entorno en aislamiento de otros posibles instrumentos de estabilización (como la política fiscal o la política de tipo de cambio). En concreto, se simula un modelo estándar Neo-Keynesiano con rigidez de precios a la Calvo bajo diferentes regimenes de política monetaria, incluida la política monetaria óptima. El reto consiste en resolver el modelo estocástico bajo la restricción explícita ocasionalmente vinculante de no negatividad de los tipos de interés. La solución supone parametrizar las expectativas y utilizar el método de solución global conocido como "colocación". Los resultados indican que la dinámica y en ocasiones los valores medios del tipo de interés, la inflación y el output gap están muy influidos por la presencia de la restricción de no negatividad. El compromiso con la regla monetaria óptima reduce las pérdidas de bienestar esperadas hasta una décima parte de las pérdidas obtenidas bajo la mejor política discrecional, mientras una política de meta constante del nivel de precios resulta en pérdidas que son sólo 60% mayores de las obtenidas bajo la regla óptima. Por otro lado, condicionado a a un choque fuerte deflacionario, las reglas instrumentarias simples funcionan mucho peor que la política óptima, aun si las pérdidas no condicionales de bienestar asociadas a dichas reglas no están muy afectadas por la presencia de la restricción de no negatividad en si.
El segundo capítulo de la tesis estudia las implicaciones de la competencia imperfecta en el mercado del petróleo, y en concreto la existencia de un conflicto relevante entre la volatilidad de la inflación y la del output gap de un país importador de petróleo. En el modelo estándar Neo Keynesiano, los choques petroleros exógenos no generan ningún conflicto de objetivos: bajo una política de metas de inflación estricta, la caída del output es exactamente igual a la contracción eficiente del output en respuesta al choque. Este capitulo propone una extensión del modelo básico en la cual la presencia de un proveedor de petróleo dominante (OPEP) lleva a fluctuaciones ineficientes en el margen del precio del petróleo que reflejan una distorsión dinámica en el proceso de producción de la economía. Como consecuencia, ante choques provinientes del sector de petróleo, una política de estabilidad de los precios no conlleva automáticamente a una estabilización de la distancia del output de su nivel eficiente y existe un conflicto entre los dos objetivos. El modelo se aleja de la discución los efectos de cambios exógenos en el precio del petróleo y se acerca al análisis de las implicaciones de los factores fundamentales que provocan los cambios en el precio del petróleo en primer lugar. Esto último representa una ventaja clara frente a la literatura existente, la cual trata tanto los efectos macroeconómicos como las implicaciones para la política monetaria de cambios en el precio del petróleo como si éstos fueran independientes de los factores fundamentales provocando dicho cambio. A diferencia de esta literatura, el análisis del capitulo II demuestra cómo frente al mismo cambio en el precio del petróleo, un banco central puede encontrar deseable bien subir o bajar el tipo de interés en función del origen del choque.
El tercer capitulo estudia el grado en que el ascenso de la estabilidad macroeconómica en EE.UU. a partir de mediados de los 80 se puede atribuir a cambios en la naturaleza de los choques petroleros y/o el peso del petróleo en el PIB. Con este propósito se estima el modelo desarrollado en el capitulo II con métodos Bayesianos utilizando datos macroeconómicos de dos periodos - antes y después de 1984 - y se conducen simulaciones contrafactuales. Las simulaciones permiten dos explicaciones alternativas de la "Gran Moderación": (1) menores choques no petroleros; y (2) mejor política monetaria. Los resultados apuntan a que el petróleo ha jugado un papel no-trivial en la moderación. En particular, el menor peso del petroleo en el PIB a partir de 1984 ha contribuido a una tercera parte de la moderación de la inflación y un 13% de la moderación del output. Al mismo tiempo, un 7% de la moderación del PIB y 11% de la moderación de la inflación se pueden atribuir a menores choques petroleros.

Using MSA level data, the paper shows, that geographic areas which experienced the largest housing bubble generally suffered a more serious subsequent economic downturn. More specifically, the paper establishes that MSAs with larger declines in housing permits had larger increases in unemployment. There also appears to be strong evidence of a correlation between the magnitude of a housing boom and the timing of the decline in housing permits. MSAs which experienced larger real housing inflation offered early indications of the subsequent Great Recession.

This thesis consists of three self-contained papers on U.S. monetary policy. The first paper examines monetary policy in the early 2000s, a prolonged period of low interest rates for which the efficacy of policy is intensely debated. Through the lens of an estimated simple New Keynesian (NK) model, the paper finds that when measuring inflation using headline CPI, the Federal Reserve's response to inflation turns out to be passive, therefore implying indeterminacy. Only when measuring inflation using core PCE does monetary policy appear to have been sufficiently active to rule out indeterminacy. Faced with this dilemma, the paper finally estimates an extended model that distinguishes between core and headline inflation. Estimation results from this model decisively rule out indeterminacy and suggest that indeed the Fed has put more weight on core PCE. The second paper contrasts interest rate rules featuring fixed versus time-varying inflation target. It finds that the rule embedding time variation in inflation target empirically fits better and that the Fed has been responding strongly to the inflation gap not only in the Great Moderation period but also in the Great Inflation era. Therefore, this finding rules out self-fulfilling inflation expectations as an explanation of the high inflation episode in the 1970s. The paper also documents that changes in monetary policy have dampened most of the fluctuations in the inflation gap and contributed to the decline in its persistence and predictability. The third paper investigates the impact of commodity price fluctuations on monetary policy and estimates a NK model with an explicit role for commodity price fluctuations. It finds that the pre-Volcker period is characterized by a determinate version of the model featuring high degree of real wage rigidity In this environment, the commodity price shocks of the 1970s created a severe trade-off between inflation and output gap stabilization. Faced with this puzzle, the central bank chose to react aggressively to both inflation and output growth, but not to the output gap, thereby ruling out indeterminacy. The paper further documents that oil price shocks are no longer as inflationary as they used to be due to a decline in real wage rigidity, thereby explaining the resilience of the economy to sustained oil price hikes in the 2000s.

The period from 1960 to 2000 saw a major evolution in monetary policy and institutions. This dissertation makes the claim that there is a better explanation of these events than the typical narrative, or dominant discourse. The typical narrative is that a relationship between inflation and unemployment (the Phillips Curve) was proposed around 1960. One interpretation of the relationship was that increasing aggregate demand would reduce unemployment with some acceptable inflation. Milton Friedman then stated in 1968 that, in the long run, this practice would entrench inflationary expectations and there would be no useful employment benefits. This was accepted by the economics profession, especially by the mid-1970s, around the time of the first oil shock. This period also saw the rise of stagflation and the countries that managed the inflationary outbreak best were those where independent central banks were able to withstand politicians’ short term instincts. Economists attributed this to a commitment concept; if governments could override their central bank only at the cost of legislation or constitutional change, then monetary policy would focus more on long term expectations, rather than the political short term. Empirical work in the 1990s established this relationship and many countries made their central banks more independent during this decade. A better view acknowledges some features of this narrative. For example, Milton Friedman’s theory of expectations was very influential. (Chapter 2). But there is reduced evidence for the rest of this narrative. For example, the Federal Reserve did tighten monetary policy after 1982 compared with the period before 1979, but this appears to have been through placing less emphasis on output instead of being more inflation averse. Further, policymakers in the late 1960s and 1970s underestimated the level of unemployment at which inflation started increasing. (Chapter 3). Politicians were generally involved in disinflations, but their role and visibility decreased as legal inflation and central bank independence (CBI) increased. This suggests that, in practice, legal independence bestows the disinflation role on the central bank (Chapter 4). The role of politicians, however, is not fully clear because the proportion of elections where a voter backlash against inflation occurred was small. Therefore, the political dynamic against inflation may have occurred through elites, rather than popular opinion (Chapter 5). Finally, there was not a strong correlation between CBI in developed countries because the literature made errors of omitted variable bias and not examining whether CBI was endogenous. Inflation in the 1970s and 1980s was more clearly related to economic factors such as currency performance, output, past inflation, oil prices, and a time trend (Chapter 6). The weakness of CBI theory is that, by excluding politics, it overstates the costs of overriding a central bank. If there is little popular support for disinflation, then the costs of overriding the central bank will be low, regardless of the legal arrangements in place. Central banks perceive this and deliver policy within the politically palatable decision set.

The war against Germany was perceived by the majority of English Canadians as a necessity to defend the British Empire, democracy and justice. However, it became increasingly evident to the public that some individuals were being permitted to prosper, while others — particularly those of the working class — endured immense hardship. These individuals who prospered at a level judged excessive became known as "profiteers." Initial criticisms of profiteering were connected to graft, jobbery and patronage apparent in government military purchases. However, as public sacrifices intensified, the morally acceptable extent to which individuals and businesses could profit came to be more narrowly defined. Criticisms of profiteering expanded to challenge the mainstream liberal notions of private wealth and laissez-faire policies as being inequitable and undemocratic. The federal government's unwillingness to seriously implement measures against profiteering led to rising discontent. Consequently, working-class English Canadians aspired to form a 'new democracy' that was worth the sacrifices of the war.

Abstract In order to study the safe distance between twin-parachute during their inflation process for fighter ejection escape, the fighter was equipped with two canopies and two seats, two types of parachute were used to numerically simulate their inflation process, respectively. One of them is C-9, the other a slot-parachute (S-P). Their physical models were built, then the meshes inside and around both parachutes were generated for fluid-structure interaction (FSI) simulation. The penalty function and the arbitrary Lagrangian-Eulerian (ALE) method were employed in the FSI simulation. To validate the numerical model for FSI simulation, at first the single parachute of the twin-parachute was used for the FSI simulation, the predicted inflation times for both types of parachute were compared with the experimental data. The computed results are in good agreement with experimental data. As a result, the inflation times were predicted with twin-parachute for both kinds of parachute. On the basis of the locations of ejected seats after the separation of seat and pilot, the initial locations and orientations of twin-parachute were also obtained. The numerical simulations for both kinds of parachute were performed by the FSI method, respectively. Our results illustrate that when the interval time for two seats ejected is greater than 0.25s, two pilots attached the twin-parachute are safe, and the twin-parachute would not interfere each other. Moreover, our results also indicate that the FSI simulation for twin-parachute inflation process is feasible for engineering applications and have a great potential for wide use.

"The administration performs a great task in the life of modern societies, through its intervention to satisfy public needs through the establishment and management of public utilities that aim to achieve the public interest and respond to the requirements and necessities of daily life, as well as protecting public order, and regulating the relationship between them and individuals with constitutional and legal texts, as well as The organizational rules that lay down the general framework for public liberties and individual rights, all to prevent them from practicing any activity outside the framework of legality. Originally, the administration is not obligated to issue its decisions in a specific form, as it is free to choose the external form of these decisions, unless the law requires it otherwise. This requires that the decision be embodied in an external form in order for individuals to know the will of the administration and to adjust their behavior according to its requirements. However, the implementation of this rule on its launch, may negatively affect the rights of individuals, because the administration may sometimes deliberately remain silent about deciding the requests submitted to it, or it may neglect at other times to respond to these requests. Existence of apparent decisions in an external legal form, meaning that the matter remains in the hands of the administration, if it wants it will respond to the requests of individuals, and if it wants to be silent, which constitutes a waste of their rights, a violation of the principle of equality, and confiscation of the right to litigation guaranteed by the constitution, it requires protection of individuals from the inconvenience of the administration And the abuse of their rights, and put an end to the neglect of employees and their indifference to the requests or grievances submitted to them, in addition to the fact that the requirements of the public interest require that the administrative staff exercise the powers entrusted to them by law at the present time. ( ) For these justifications, the legislator intervened in many countries, including France, Egypt, Lebanon and Iraq, to ​​suppose that the administration had announced its will, even if it remained silent or silent about deciding on the request presented to it, and this resulted in an implicit administrative decision of rejection or approval. As a result of the large number of state intervention in the economic and social fields in recent times, it has led to the multiplicity and diversity of state agencies and institutions, and the public administration often does not provide its services to individuals except at the request of individuals. Therefore, it may be difficult for individuals to identify a competent administrative authority to submit their request to. to get those services. He makes a mistake and submits it to a non-competent administrative body. When this authority is silent and does not transfer the request to its competent authority, and the legal period granted to the administration to respond to their requests has passed, individuals resort to the judiciary, and submitting the request to the non-competent authority prevents the judiciary from accepting their claim, which wastes their rights and thus harms them. Therefore, the administrative judiciary in many countries has extended its control over this case to consider the application submitted to a non-competent administrative body as if it was submitted to its competent authority, given that the state is a single public legal person. Accordingly, the request submitted to any party starts from the legal period available to the administration to meet the requests of individuals and in its absence the implicit administrative decision of rejection or acceptance arises. Accordingly, we will study the jurisprudence of the French, Lebanese, Egyptian and Iraqi judiciary in this study. The importance of the study lies in the implications of the subject of requests submitted to the administration, the delay in their completion, the silence of the administration, and the consequent effects and exposure to the rights of individuals. And that it will show how to confront this silence, neglect and intransigence of the administration. The idea of ​​implicit administrative decisions, resulting from the administration’s silence on the requests submitted to it, is an effective means, which makes the administration more positive and enables individuals to confront the administration’s silence, and prevents its intransigence, arbitrariness or neglect. The problem of the research is that can silence be an expression of the will? How do individuals protect themselves from the actions of the administration, and who guarantees its non-bias, arbitrariness and deviation? Does submitting the application to a non-competent body protect the rights of individuals? ? And the extent of judicial oversight on the authority of the administration.? And the extent of the compatibility and divergence of the positions of the administrative judiciary in France, Lebanon, Egypt and Iraq regarding this.? From the above in explaining the importance of the study and its problem, we can deduce the scope of the study, which is the study of judicial control over the requests submitted to the administration by taking an overview of the nature of the requests, their types and distinguishing them from others, and the position of each of the legislation, the judiciary and jurisprudence from it. The research consists of two sections, the first deals with the nature of the request and what is related to it, and the second is judicial control over the applications submitted to the administration, as follows"

Liberal economic order, businesses efficiency, productivity and profitability, competition for work is present in accordance with the principles defended private property order. As sistematical the main foundations of economic liberalism created by Adam Smith. Then, his prenciples developed by evolving Classic School, continued to the sovereignty until the Great Depression of 1929. I.World War took place in an environment dominated by Classical Ekol During, and after the war, from the principles of Classical School had not doubt. In 1936, John Maynard Keynes, the basic assumptions of the classical school refused. Following the II. World War; the 1950s and 1960s,sounds of the proponents of the liberal principles, was not strong as much as Keynesians. In the 1970s, emerged the world's most developed economy ABD, the high unemployment and inflation. Until 1973, wasn’t confronted with a serious crisis. Content of the neo-liberal economic policies between 1975-1980 was adopted. Since the 1980s, heavily affecting the world economy started to implement neoliberal policies. Acceleration of privatization, taxes, discounts for large scale unemployment, increase monetary measures to keep inflation under control was applied. In this article, on eight chapters were created. In the chapters, concept, scope and content, historical background of privatization, investigated material causes that give rise to privatization, the basic bases of privatization, the ideological foundations of privatization. Privatization aims were discussed, and was given examples of countries is characterized by intense privatization. The general results and in Turkey latests cases were discussed.

Large deployable antennas for space applications become essential in the fields of communications, radio astronomy and Department of Defence (DOD) space-based radar. Since the antenna should be installed in a cargo space of a rocket vehicle during the launch phase, an inflatable deployment concept is inevitable to overcome the size limitation. A newly developed class of space structures, called inflatable-deployable structures, has great potential for satisfying these stringent user requirements. Among the many antenna types available, the parabolic reflector antenna is the most common one mainly due to its high gain, which enable high data rate transmission at low power. Large parabolic reflectors and solar concentrators are of great interest for the applications of satellite. This paper presents the finite element modelling of the parabolic shaped reflector to know the static and dynamic behaviour under the various inflation pressures. Purpose of this study is to highlight the dynamic characteristics of parabolic structures used in space application. The challenge is to assure that inflatable parabolic surfaces have significantly high efficiency and accuracy to satisfy the system requirements. Even the smart material is used for the control of the geometry of the reflecting surfaces and the study is done for the optimal size and placement of actuators and sensors the control of the shape of the reflecting surfaces. So this study is required to understand the dynamic characteristics i.e. frequency and mode shapes of these structures so that we can find out the maximum deflection and deformed shape of the parabolic surfaces.

The active magnetic bearings (AMB), with the advantages of no friction, no abrasion, no lubrication and active control, is used in the primary helium circulator for high-temperature gas-cooled reactor (HTR). But the magnetic bearing is a complex system, which contains sensor, controller, power amplifier circuit and actuators. Any part of failure is likely to make high-speed rotor off balanced position and fell in the inner ring of the bearing, causing huge impact and fiction heat that may damage the magnetic bearing. Therefore, it is necessary to bring the auxiliary bearing in the magnetic bearing to protect and temporarily support the high-speed rotor. The auxiliary bearings are mainly divided into two categories: rolling bearings and plain bearings. Generally speaking, for rolling bearings, the force of friction is smaller and the heat caused by it is lower during the touchdown. However, it needs to be detected online to ensure that it can work well in emergencies, and the rolling bearings has a smaller load capacity because of the point contact between the ball and the ring. Compared with the rolling bearings, the structure of plain bearings is simple and durable. With a larger load capacity and the advantage of non-contact detection, the plain bearing is gradually becoming a research hot-spot in the field of the auxiliary bearing. But the great friction and inevitable heat are also cannot be ignored. In High temperature gas-cooled reactor demonstration power station (HTR_PM), the work load of helium main fan is very large, once the support of electromagnetic bearing is out of work, the auxiliary bearing need to suffer from a very large drop impact load, which is accompanied by a huge friction fever. Therefore, it is important to develop a rolling-sliding integrated bearing which can bear heavy load and have little friction, combined with the advantages of plain bearings and rolling bearings. And that is an important direction of the development for the main helium pan in high temperature gas-cooled reactor nuclear power plant. This paper establish a simulation model for a horizontal rotor and rolling-sliding integrated auxiliary bearing system. In the case of synchronous rotation of the inner ring with the rotor, the speed of the outer race of the bearing is determined. and based on the main helium fan in HTR-PM, using the finite element analysis software LS-Dyna, the rolling-sliding integrated auxiliary bearing is proposed and the impact force and the MISES stress nephogram when the peak inflation occurred during the first impact and the axial axes displacement curve during rotor drop in the auxiliary bearing are preliminarily simulated in this paper., then certain theoretical reference is provided for the design and engineering application of the rolling-sliding integrated auxiliary bearing.

Attention to safety and health are of ever-increasing priority to industrial organizations. Good Safety is demanded by stockholders, employees, and the community while increasing injury costs provide additional motivation for safety and health excellence. Safety has always been a strong corporate value of DuPont and a vital part of its culture. As a result, DuPont has become a benchmark in safety and health performance. Since 1990, DuPont has re-engineered itself to meet global competition and address future vision. In the new re-engineered organizational structures, DuPont has also had to re-engineer its safety management systems. A special Discovery Team was chartered by DuPont senior management to determine the “best practices’ for safety and health being used in DuPont best-performing sites. A summary of the findings is presented, and five of the practices are discussed. Excellence in safety and health management is more important today than ever. Public awareness, federal and state regulations, and enlightened management have resulted in a widespread conviction that all employees have the right to work in an environment that will not adversely affect their safety and health. In DuPont, we believe that excellence in safety and health is necessary to achieve global competitiveness, maintain employee loyalty, and be an accepted member of the communities in which we make, handle, use, and transport products. Safety can also be the “catalyst” to achieving excellence in other important business parameters. The organizational and communication skills developed by management, individuals, and teams in safety can be directly applied to other company initiatives. As we look into the 21st Century, we must also recognize that new organizational structures (flatter with empowered teams) will require new safety management techniques and systems in order to maintain continuous improvement in safety performance. Injury costs, which have risen dramatically in the past twenty years, provide another incentive for safety and health excellence. Shown in the Figure 1, injury costs have increased even after correcting for inflation. Many companies have found these costs to be an “invisible drain” on earnings and profitability. In some organizations, significant initiatives have been launched to better manage the workers’ compensation systems. We have found that the ultimate solution is to prevent injuries and incidents before they occur. A globally-respected company, DuPont is regarded as a well-managed, extremely ethical firm that is the benchmark in industrial safety performance. Like many other companies, DuPont has re-engineered itself and downsized its operations since 1985. Through these changes, we have maintained dedication to our principles and developed new techniques to manage in these organizational environments. As a diversified company, our operations involve chemical process facilities, production line operations, field activities, and sales and distribution of materials. Our customer base is almost entirely industrial and yet we still maintain a high level of consumer awareness and positive perception. The DuPont concern for safety dates back to the early 1800s and the first days of the company. In 1802 E.I. DuPont, a Frenchman, began manufacturing quality grade explosives to fill America’s growing need to build roads, clear fields, increase mining output, and protect its recently won independence. Because explosives production is such a hazardous industry, DuPont recognized and accepted the need for an effective safety effort. The building walls of the first powder mill near Wilmington, Delaware, were built three stones thick on three sides. The back remained open to the Brandywine River to direct any explosive forces away from other buildings and employees. To set the safety example, DuPont also built his home and the homes of his managers next to the powder yard. An effective safety program was a necessity. It represented the first defense against instant corporate liquidation. Safety needs more than a well-designed plant, however. In 1811, work rules were posted in the mill to guide employee work habits. Though not nearly as sophisticated as the safety standards of today, they did introduce an important basic concept — that safety must be a line management responsibility. Later, DuPont introduced an employee health program and hired a company doctor. An early step taken in 1912 was the keeping of safety statistics, approximately 60 years before the federal requirement to do so. We had a visible measure of our safety performance and were determined that we were going to improve it. When the nation entered World War I, the DuPont Company supplied 40 percent of the explosives used by the Allied Forces, more than 1.5 billion pounds. To accomplish this task, over 30,000 new employees were hired and trained to build and operate many plants. Among these facilities was the largest smokeless powder plant the world had ever seen. The new plant was producing granulated powder in a record 116 days after ground breaking. The trends on the safety performance chart reflect the problems that a large new work force can pose until the employees fully accept the company’s safety philosophy. The first arrow reflects the World War I scale-up, and the second arrow represents rapid diversification into new businesses during the 1920s. These instances of significant deterioration in safety performance reinforced DuPont’s commitment to reduce the unsafe acts that were causing 96 percent of our injuries. Only 4 percent of injuries result from unsafe conditions or equipment — the remainder result from the unsafe acts of people. This is an important concept if we are to focus our attention on reducing injuries and incidents within the work environment. World War II brought on a similar set of demands. The story was similar to World War I but the numbers were even more astonishing: one billion dollars in capital expenditures, 54 new plants, 75,000 additional employees, and 4.5 billion pounds of explosives produced — 20 percent of the volume used by the Allied Forces. Yet, the performance during the war years showed no significant deviation from the pre-war years. In 1941, the DuPont Company was 10 times safer than all industry and 9 times safer than the Chemical Industry. Management and the line organization were finally working as they should to control the real causes of injuries. Today, DuPont is about 50 times safer than US industrial safety performance averages. Comparing performance to other industries, it is interesting to note that seemingly “hazard-free” industries seem to have extraordinarily high injury rates. This is because, as DuPont has found out, performance is a function of injury prevention and safety management systems, not hazard exposure. Our success in safety results from a sound safety management philosophy. Each of the 125 DuPont facilities is responsible for its own safety program, progress, and performance. However, management at each of these facilities approaches safety from the same fundamental and sound philosophy. This philosophy can be expressed in eleven straightforward principles. The first principle is that all injuries can be prevented. That statement may seem a bit optimistic. In fact, we believe that this is a realistic goal and not just a theoretical objective. Our safety performance proves that the objective is achievable. We have plants with over 2,000 employees that have operated for over 10 years without a lost time injury. As injuries and incidents are investigated, we can always identify actions that could have prevented that incident. If we manage safety in a proactive — rather than reactive — manner, we will eliminate injuries by reducing the acts and conditions that cause them. The second principle is that management, which includes all levels through first-line supervisors, is responsible and accountable for preventing injuries. Only when senior management exerts sustained and consistent leadership in establishing safety goals, demanding accountability for safety performance and providing the necessary resources, can a safety program be effective in an industrial environment. The third principle states that, while recognizing management responsibility, it takes the combined energy of the entire organization to reach sustained, continuous improvement in safety and health performance. Creating an environment in which employees feel ownership for the safety effort and make significant contributions is an essential task for management, and one that needs deliberate and ongoing attention. The fourth principle is a corollary to the first principle that all injuries are preventable. It holds that all operating exposures that may result in injuries or illnesses can be controlled. No matter what the exposure, an effective safeguard can be provided. It is preferable, of course, to eliminate sources of danger, but when this is not reasonable or practical, supervision must specify measures such as special training, safety devices, and protective clothing. Our fifth safety principle states that safety is a condition of employment. Conscientious assumption of safety responsibility is required from all employees from their first day on the job. Each employee must be convinced that he or she has a responsibility for working safely. The sixth safety principle: Employees must be trained to work safely. We have found that an awareness for safety does not come naturally and that people have to be trained to work safely. With effective training programs to teach, motivate, and sustain safety knowledge, all injuries and illnesses can be eliminated. Our seventh principle holds that management must audit performance on the workplace to assess safety program success. Comprehensive inspections of both facilities and programs not only confirm their effectiveness in achieving the desired performance, but also detect specific problems and help to identify weaknesses in the safety effort. The Company’s eighth principle states that all deficiencies must be corrected promptly. Without prompt action, risk of injuries will increase and, even more important, the credibility of management’s safety efforts will suffer. Our ninth principle is a statement that off-the-job safety is an important part of the overall safety effort. We do not expect nor want employees to “turn safety on” as they come to work and “turn it off” when they go home. The company safety culture truly becomes of the individual employee’s way of thinking. The tenth principle recognizes that it’s good business to prevent injuries. Injuries cost money. However, hidden or indirect costs usually exceed the direct cost. Our last principle is the most important. Safety must be integrated as core business and personal value. There are two reasons for this. First, we’ve learned from almost 200 years of experience that 96 percent of safety incidents are directly caused by the action of people, not by faulty equipment or inadequate safety standards. But conversely, it is our people who provide the solutions to our safety problems. They are the one essential ingredient in the recipe for a safe workplace. Intelligent, trained, and motivated employees are any company’s greatest resource. Our success in safety depends upon the men and women in our plants following procedures, participating actively in training, and identifying and alerting each other and management to potential hazards. By demonstrating a real concern for each employee, management helps establish a mutual respect, and the foundation is laid for a solid safety program. This, of course, is also the foundation for good employee relations. An important lesson learned in DuPont is that the majority of injuries are caused by unsafe acts and at-risk behaviors rather than unsafe equipment or conditions. In fact, in several DuPont studies it was estimated that 96 percent of injuries are caused by unsafe acts. This was particularly revealing when considering safety audits — if audits were only focused on conditions, at best we could only prevent four percent of our injuries. By establishing management systems for safety auditing that focus on people, including audit training, techniques, and plans, all incidents are preventable. Of course, employee contribution and involvement in auditing leads to sustainability through stakeholdership in the system. Management safety audits help to make manage the “behavioral balance.” Every job and task performed at a site can do be done at-risk or safely. The essence of a good safety system ensures that safe behavior is the accepted norm amongst employees, and that it is the expected and respected way of doing things. Shifting employees norms contributes mightily to changing culture. The management safety audit provides a way to quantify these norms. DuPont safety performance has continued to improve since we began keeping records in 1911 until about 1990. In the 1990–1994 time frame, performance deteriorated as shown in the chart that follows: This increase in injuries caused great concern to senior DuPont management as well as employees. It occurred while the corporation was undergoing changes in organization. In order to sustain our technological, competitive, and business leadership positions, DuPont began re-engineering itself beginning in about 1990. New streamlined organizational structures and collaborative work processes eliminated many positions and levels of management and supervision. The total employment of the company was reduced about 25 percent during these four years. In our traditional hierarchical organization structures, every level of supervision and management knew exactly what they were expected to do with safety, and all had important roles. As many of these levels were eliminated, new systems needed to be identified for these new organizations. In early 1995, Edgar S. Woolard, DuPont Chairman, chartered a Corporate Discovery Team to look for processes that will put DuPont on a consistent path toward a goal of zero injuries and occupational illnesses. The cross-functional team used a mode of “discovery through learning” from as many DuPont employees and sites around the world. The Discovery Team fostered the rapid sharing and leveraging of “best practices” and innovative approaches being pursued at DuPont’s plants, field sites, laboratories, and office locations. In short, the team examined the company’s current state, described the future state, identified barriers between the two, and recommended key ways to overcome these barriers. After reporting back to executive management in April, 1995, the Discovery Team was realigned to help organizations implement their recommendations. The Discovery Team reconfirmed key values in DuPont — in short, that all injuries, incidents, and occupational illnesses are preventable and that safety is a source of competitive advantage. As such, the steps taken to improve safety performance also improve overall competitiveness. Senior management made this belief clear: “We will strengthen our business by making safety excellence an integral part of all business activities.” One of the key findings of the Discovery Team was the identification of the best practices used within the company, which are listed below: ▪ Felt Leadership – Management Commitment ▪ Business Integration ▪ Responsibility and Accountability ▪ Individual/Team Involvement and Influence ▪ Contractor Safety ▪ Metrics and Measurements ▪ Communications ▪ Rewards and Recognition ▪ Caring Interdependent Culture; Team-Based Work Process and Systems ▪ Performance Standards and Operating Discipline ▪ Training/Capability ▪ Technology ▪ Safety and Health Resources ▪ Management and Team Audits ▪ Deviation Investigation ▪ Risk Management and Emergency Response ▪ Process Safety ▪ Off-the-Job Safety and Health Education Attention to each of these best practices is essential to achieve sustained improvements in safety and health. The Discovery Implementation in conjunction with DuPont Safety and Environmental Management Services has developed a Safety Self-Assessment around these systems. In this presentation, we will discuss a few of these practices and learn what they mean. Paper published with permission.
