Повний текст джерелаThere was a fairly steady increase in temporary agency work (TAW) in France between 1972 and 2004, whereas that work was strictly regulated by rules that remained unchanged. This doctoral thesis aims at accounting for this a priori paradoxical increase. The research is based upon multilevel, strategic and systemic studies. The behaviours of individuals who are involved in the TAW system and in a similar social network were observed : temporary workers, user firms, temporary work agencies, and agents of public services who belong to 8 segments of the labour market connected to 4 sectors - logistics, transportation, architecture and call centres. The contexts of their action, employment, economic and judicial situations were examined within several conceptual frameworks : sociologies of work, employment, market and law, economic and financial analyses. Thus, the legal constraints, the high cost of TAW for workers, users and agencies and the unpredictability of their behaviours, which at first sight seemed to interfère with the development of TAW, were thoroughly analysed ; they can accotait for the way the transactions between these individuals, developed and lasted. These elements turn out to be the very conditions for this collective gaine. More legally bound and controlled than the others, the agencies know how to control their constraints and those of theirs "partners". They also manage to turn them into resources, to make temporary workers and users dependent, even though the latter seem to be a priori free. They finally manage to share out the costs of those transactions. They transfer part of the costs to the 3 main parties of the TAW system and the rest to other parties

Повний текст джерелаThe purpose of this thesis is to examine the temporary contracts and its impacts on labour mobility in France. In a first part, we aim at investigating the determinant to use temporary contract. The theoretical analyses intend to explain that temporary contracts are a solution to the moral hazard, adverse selection, job matching and uncertainty affecting the external environment of the firm. The econometric evaluation from the French Labour Survey of these determinants confirms the positive effect of contracting costs evoked by the literature on the contract duration. The second part examined whether temporary contracts deserve to be considered as stepping stones to permanent ones. Using French Labour Survey, our results show that, for men and women, the transition to permanent contract decreases after 12th months. After a temporary contract in the public sector, compared to private, the workers are more likely to fall again into unemployment or another temporary contract. The third part studies the impact of the individual transition from a temporary job (CDD) to permanent job (CDI) on the wage. We present the transition from a temporary job to a permanent one as a simple tournament mechanism. The equilibrium properties of the model show that wages differences between temporary jobs and permanent ones are positively correlated with uncertainty during tournament. Using French Labour Survey, using a firm size as a proxy for uncertainty, our results do not reject the equilibrium property of the model according to which more uncertainty during tournament reduces players’ incentives and would be compensated by an increased wage gap between promoted and not promoted

Повний текст джерелаThis thesis study the dualism existing on the French labor market. Especially, I study job and worker flows and the role played by temporary contracts in those flows. The employment protection legislation is stringent in France then firms are subject to important rules when they adjust their workforce. However, it seems that the employment legislation governing the use of temporary contracts is not so binding in practice since this type of contract is widely used and that their duration is more and more shorter. In order to have a better knowledge of the French labor market and of the dualism, this thesis is divided in three chapters. The first one quantifies job and worker flows over the 1998-2012 period and explores the possible impact of the 2008 crisis on those flows taking into account industry characteristics. In addition, I study the evolution of contracts' duration and I propose an econometric analysis that highlight the determinants of temporary hirings.The second chapter quantifies transitions existing on the French labor market and their impact on unemployment volatility. I use a three-state (employed, unemployed, inactive) and a four-state model (permanently employed, temporary employed, unemployed, inactive). This latest model has never been studied for the French case yet.Finally, the last chapter analyzes the consequences of the implementation of a tax on short-term contracts that is supposed to encorage firms to hire with permanent contracts and increase the duration of contracts. This kind of reform has been in several european countries. In France, this tax was implemented by the Interprofessional agreement in july 2013. A search and matching model is estimated on French data from UNEDIC using the model proposed by Caguc, Charlot and Malherbet (2016)

Повний текст джерелаThis enquiry studies the birth and the development of high level temporary workers (professionals). The aimis the explanation of the conditions of emergency and developement of this new way of working. The objective is to show all actors concerned act to create a development of temporary work and how they regulate this specific employment market. The hypothesis is that organisational transformation of the firms leads to create high level temporary work. Actually enterprises employ so much high level temporary workers that temporary compagnies decided to get this new market ; to succeed they changed their structures to adapt themselves to this new market. The observations demonstrate that organisations develop a supplementary level of rationalisation and externalisation. This study shows how bad conditions of the employment market create new norms about work concerning professionals

Повний текст джерелаThe study presents a regional, panel-based model of the long term and short-term evolution of real estate prices in the administrative regions of Quebec. Allowing that dynamic adjustment to be different from one region to another, we find income elasticity (i.e. cointegration coefficients) that differ considerably one region to the next. In addition, since migratory shocks have potentially different effects from equivalent shocks related to natural increases, we show that migration has a higher effect on the real estate market. The age composition of the population also has a significant effect on average prices, both for young people (25 to 54 years) and for older people (65 years and over). These results suggest that using a panel model not allowing for differentiated regional dynamics leads to potentially less robust conclusions.

Повний текст джерелаPlus largement, la thèse interroge la pertinence du postulat qui veut que les politiques migratoires conçues et mises en oeuvre par les pouvoirs publics, au cours des Golden Sixties, aient considéré les travailleurs migrants comme une main-d’oeuvre d’appoint temporaire.
La première partie de la thèse, qui porte sur la genèse de la politique d’immigration belge entre 1830 et 1960, recadre l’histoire de l’immigration turque dans l’industrie houillère belge et des politiques mises en oeuvre à son intention dans le contexte du double processus d’étatisation et de nationalisation des politiques migratoires au cours des XIXe et XXe siècles.
La seconde partie retrace la configuration des chaînes d’interdépendances qui relient les trajectoires migratoires des travailleurs migrants turcs recrutés par l’industrie charbonnière belge dans les années 1960 et 1970 aux dispositifs générés, séparément ou conjointement, par l’Etat belge, l’Etat turc, l’industrie charbonnière, les organisations syndicales et les services, associations et autres collectifs d’accueil et d’aide aux migrants pour organiser, stabiliser et intégrer cette immigration turque dans les régions minières du pays.
La troisième partie interroge le devenir de cette immigration turque au moment où les fermetures de charbonnages se succèdent et que de nouveaux besoins en main-d’oeuvre se font sentir dans les dernières sociétés charbonnières encore en activité. Elle esquisse en parallèle le processus d’étatisation des politiques d’intégration jusque-là principalement prises en charge par les modes de gestion paternalistes de l’industrie charbonnière.
Cette thèse aborde également, mais dans une moindre mesure, l’immigration originaire de Turquie avant 1960 et l’immigration turque qui se développe au cours des années 1960 et 1970, en marge de celle organisée en faveur de l’industrie charbonnière, à destination d’autres régions et secteurs d’activité du pays (Bruxelles, Anvers, Gand, Ardennes, etc.).
Son angle d’approche dépasse par ailleurs la seule immigration turque en Belgique et la seule politique migratoire belge. Elle s’intéresse ainsi, à travers des analyses comparées, au cas de l’immigration marocaine, qui lui est contemporain, ou encore à la politique migratoire néerlandaise, à l’origine d’un phénomène de désertion massive de l’industrie houillère belge par les ouvriers mineurs turcs.

Повний текст джерелаIn this thesis, we study several mathematical finance problems related to the presence of market imperfections. Our main approach for solving them is to establish a relevant asymptotic framework in which explicit approximate solutions can be obtained for the associated control problems. In the first part of this thesis, we are interested in the pricing and hedging of European options. We first consider the question of determining the optimal rebalancing dates for a replicating portfolio in the presence of a drift in the underlying dynamics. We show that in this situation, it is possible to generate positive returns while hedging the option and describe a rebalancing strategy which is asymptotically optimal for a mean-variance type criterion. Then we propose an asymptotic framework for options risk management under proportional transaction costs. Inspired by Leland’s approach, we develop an alternative way to build hedging portfolios enabling us to minimize hedging errors. The second part of this manuscript is devoted to the issue of tracking a stochastic target. The agent aims at staying close to the target while minimizing tracking efforts. In a small costs asymptotics, we establish a lower bound for the value function associated to this optimization problem. This bound is interpreted in term of ergodic control of Brownian motion. We also provide numerous examples for which the lower bound is explicit and attained by a strategy that we describe. In the last part of this thesis, we focus on the problem of consumption-investment with capital gains taxes. We first obtain an asymptotic expansion for the associated value function that we interpret in a probabilistic way. Then, in the case of a market with regime-switching and for an investor with recursive utility of Epstein-Zin type, we solve the problem explicitly by providing a closed-form consumption-investment strategy. Finally, we study the joint impact of transaction costs and capital gains taxes. We provide a system of corrector equations which enables us to unify the results in [ST13] and [CD13]

Повний текст джерелаThe relationship between investor sentiment and asset valuation is at the center of a long-running debate in behavioral finance. The purpose of this thesis is to study the impact of investor sentiment on the stock return. First of all, this thesis develops a new measure of investor sentiment witch combines both the direct and indirect indicators. Using vector autoregressive model, we find that investor sentiment affect stocks whose valuations are highly subjective and are difficult to arbitrage. Furthermore, we find that past returns are an important determinant of sentiment. Lastly, we find that our composite index provide a better predictive power than three alternative proxies for investor sentiment. Secondly, we test if the financial markets price the investor's sentiment risk. We construct portfolios considering the stock returns exposure to sentiment. Our results show that the performance is positively correlated with the exposure of stock to sentiment. The strategy consisting in buying the stocks with the highest exposure to sentiment and selling stocks having the lowest exposure generates a significant raw profit. Exploring the sources of profitability, we show that neither the traditional risk factors nor the momentum factor can account for the profitability. However, the addition of the sentiment risk, will contribute to the explanation of the profit

Повний текст джерелаSince recent decades, the European Union has been subject to exogenous shocks which are linked to new generation crisis such as emerging crisis or disturbances from American financial markets (L. T. C. M. , Enron, Worldcom and the bursting of the technologic speculative bubble). In addition, changes in the international economic landscape, the evolution of technological advances, markets deregulation, the creation of new forms of financing, the emergence of new actors, changing fields of action of traditional actors such as banks and the onset or exacerbation of risk or shocks lead Europe to take on new challenges. Can we say that Europe is subject to contagion? If it’s the case, at what time and for which types of events is it possible ? What are the european financial markets in which the impact of negative shocks is the most significant relatively to positive shocks ? What are the mechanisms or buffer-factors in Europe that could absorb financial shocks ?

Повний текст джерелаThe present research aims to contribute to the market orientation performance paradigm. By adopting a customer perspective, as advocated by Deshpandé, Farley and Webster (1993), it raises the issue of the potential effects of market orientation on customer performance, especially when studied through the distributor satisfaction. The objective of this research is to hold and test a theoretical relationship model including the organisation’s market orientation, the corresponding customer’s evaluation, the market orientation gap and the distributor satisfaction, this latter being considered through its economic and social aspects, while assessed by a direct and objective measure. Our results are in accordance with many of the studies taken into this research stream. The first relationship does not exist, the second is confirmed with a strong effect for the economic satisfaction and a somewhat week one when social satisfaction is considered. Finally, the negative impact of the market orientation gap on distributor satisfaction is observable only when dealing with economic satisfaction. Behind its contribution to a better understanding of the market orientation phenomenon and its relationship with organizational performance, this research raises a variety of important research issues about the sometimes controversial universality of the market orientation concept and the value of taking into account other relevant dimensions of organizational performance, such as those representing the customer-related performance
Vari, Miklos. "The impact of central bank policies on money markets." Thesis, Paris 1, 2017. http://www.theses.fr/2017PA01E062.
Повний текст джерелаThe first chapter shows how interbank market fragmentation disrupts the transmission of monetary policy. Fragmentation is the fact that banks, depending on their country of location,have different probabilities of default on their interbank borrowings. Once fragmentation is introduced into standard theoretical models of monetary policy implementation, excess liquidity arises endogenously. This leads short-term interest rates to depart from the central bank policy rates. Using data on cross-border financial flows and monetary policy operations,it is shown that this mechanism has been at work in the Euro-Area since 2008. The model is used to analyze conventional and unconventional monetary policy measures. The second chapter shows how the Euro area money market rates have been standing below the deposit facility rate since 2015, which financial markets perceive as a byproduct of Eurosystem's public sector purchase program (PSPP). This paper explores empirically the interactions between the PSPP and short term secured money market rates (repo rates). We document different channels through which asset purchases may affect the various segments of the Euro area repo market. Using proprietary data from the PSPP and individual repo transactions made on the repo market for specific securities, our results show that the PSPP has contributed to push down repo rates. Purchasing 1% of a bond outstanding is associated with a decline in its repo rate of -0.75 bps

Повний текст джерелаThis thesis addresses aspects of interacting markets in electricity wholesale. Electricity is traded in forward markets and in day-ahead auctions, which implement a very specifie market design. The bids of market participants take the fonn of supply and demand functions. Chapter 2 builds upon a finding of Zachmann and von Hirschhausen (2008) who report an asymmetric response of electricity wholesale prices for Gennany to changes in the price of EV Emission Allowances (EVA). ln contrast to the fonner contribution, it is shown that the asymmetry disappeared in response to a report on investigations by the competition authority. Chapter 3 addresses the interaction offorward markets and day-ahead auctions in a repeated oligopoly game. The effect offorward trading on the sustainability of collusion is studied for the case that spot market strategies take the fonn of supply functions. It is shown that the existence of forward markets enlarges the range of discount factors for which collusion can be sustained. Chapter 4 examines if an asymmetric reaction to EVA prices can also be found in the supply functions from the day-ahead market. To this end, tools from the field of functionaJ data analysis are adopted and applied to observed bids from the day-ahead auction. Chapter 5 develops a test for autocorrelation in functional panel data. Asymptotic nonnality of the statistic is proved, and Monte-Carlo simulation sho\l good power of the test in sample sizes which frequently prevail in applied research

Повний текст джерелаThe tax contributions describes the whole of fiscal contributions and social contributions. It affects the individual behaviours and therefore the supply and demand labour. According to the microecnomics foundations of macroeconomics, the employers and workers response - after a change in tax and contributions - can lead to substantial growth and employment variations. This thesis analyses the composition of tax revenues and examines the institutional aspects of labour markets of three countries group among OECD. It points out that equity and efficiency of fiscal structures - affecting growth, employment and well being - depends of national culture. The term of "culture" includes economics behaviour, fiscal redistribution and welfare systems, choice politics about the nature of contribution making up fiscal structure and bargaining collective models. . .

Повний текст джерелаWithin the financial globalization context, developing countries are called to follow the developed ones by opening their capital account. Many theoretical arguments support the relationship between financial liberalization and economic growth. While proponents of capital account liberalization cite the channels conducting the benefits of cross-border capital flows, opponents mention recent crisis that it directly or indirectly caused in many developing countries. Empirical studies refer to a controversy. Aware of risks associated to the disorderly financial liberalization, we try through this paper to answer the following question: how to conduct a capital account liberalization that is able to lead to an optimal economic growth? In this paper, we focus on the effects of capital account liberalization along with testing them with reference to the nine Mediterranean countries that took part to Euro-Mediterranean partnership over the period 1984-2005. We also try to identify the requisite financial conditions that lead to a financial integration success. We show that the effects of capital account liberalization on growth depend on the financial environment in which that policy occurs, and the banking system fragility in particular, that can explain the negative prior effect of financial liberalization found by our estimations

Повний текст джерелаClassical derivatives pricing theory assumes frictionless market and infinite liquidity. These assumptions are however easily violated in real market, especially for large trades and illiquid assets. In this imperfect market, one has to consider the super-replication price as perfect hedging becomes infeasible sometimes.The first part of this dissertation focuses on proposing a model incorporating both liquidity cost and price impact. We start by deriving continuous time trading dynamics as the limit of discrete rebalancing policies. Under the constraint of holding zero underlying stock at the inception and the maturity, we obtain a quasi-linear pricing equation in the viscosity sense. A perfect hedging strategy is provided as soons as the equation admits a smooth solution. When it comes to hedging a covered European option under gamma constraint, the dynamic programming principle employed previously is no longer valid. Using stochastic target and partial differential equation smoothing techniques, we prove the super-replication price now becomes the viscosity solution of a fully non-linear parabolic equation. We also show how ε-optimal strategies can be constructed, and propose a numerical resolution scheme.The second part is dedicated to the numerical resolution of the Backward Stochastic Differential Equation (BSDE). We propose a purely forward numerical scheme, which first approximates an arbitrary Lipschitz driver by local polynomials and then applies the Picard iteration to converge to the original solution. Each Picard iteration can be represented in terms of branching diffusion systems, thus avoiding the usual estimation of conditional expectation. We also prove the convergence on an unlimited time horizon. Numerical simulation is also provided to illustrate the performance of the algorithm

Повний текст джерелаFirm, city and regional level data for Russia, years 1999-2008, is employed to analyze the effects of agglomeration level and home market potential (HMP) on enterprise productivity and location choice. City average wages, transport infrastructure and business environment are considered. Our motivation is search for sources of economic development in the Russian cities, which differ significantly in their initial conditions and present situation. Agglomeration economies are associated with the opportunities for input sharing, matching and knowledge spillovers. In Chapter 3, urbanization and diversity economies as well as HMP are found to be positive. Localization economies have an inverted U shape for the majority of specifications, but are positive for the monotowns, showing the importance of firms’ concentration in the same industry for enterprise performance. Urbanization economies are important for the monotowns too. In Chapter 4, it is found that urbanization economies arising from presence both of national and foreign firms are positive, while those arising from the foreign firms’ presence are relatively larger. Localization economies arising from the national firms’ presence have an inverted U shape; localization effects arising from the foreign firms’ presence are contradictory. In Chapter 5, enterprise location choice for a city is estimated. Both urbanization economies and HMP positively affect location choice; localization economies keep the inverted U shape. Foreign firms’ choice for a city is more affected by agglomeration, HMP and institutional infrastructure, probably as they have greater opportunities than the national firms to choose location

Повний текст джерелаThe research focuses on links between the growth strategy of non financial firms and its funding in France since the beginning of the i980s. According to this objective, Empirical work consists in a comparison of the phenomena observed at the microeconomic levee on the basis of the consolidated accounts of major quoted croups, and at the macroeconomic level on the basis of french national accounts. The thesis points out two main facts. Within the framework of financialised growth regime, and under the leadership of the major quoted croups, french firms' investment (i) follows a depressive path in the long run, which becomes even more obvious during last years; and (ii) is involved in a deflationary financial cycle. These results are tested through VECM modeling on national accounts data and through a panel of major croups quoted on the SBF 250 index, using the first-d1fferences GMM estimator. The behavioural equations which are estimated are issued from stock-flow coherent post-keynes1an models

Повний текст джерелаPublic interest gives harbours a specific legal and institutional framework. Harbour facilities must work continuously and stay available to every user, according to the limitations required to satisfy everybody. As such, they are traditionally subject to the state ownership system and their related activities are subject to the public service one. Both systems are exorbitant by nature. Applying them simultaneously triggers off an overprotection detrimental to harbours competitivity.This study aims at showing the harbour state ownership system is unsuitable, both in terms of overall consistency and its impact on the harbour site growth. Adoption of the general code ruling the public ownership and posterior reforms did not allow to resolve the harbour state ownership hypertrophy issue, nor did they establish an ownership system truly appropriate.Appearing harbour terminals contracts constitute a major but still insufficient evolution. If they do allow to share risks between harbour authorities and private operators to some extent, unfortunately they did not resolve the ownership activities precarity issue. Legal insecurity remains, which does not stimulate private investment.Against competition law obligations and the free movement of goods and people spreading within the EU, harbour facilities management terms need to adapt to today’s market economy challenges
Challita, Sandra. "Impact de la structure de propriété sur les stratégies de marché et la performance et le risque financiers : Une approche multisectorielle." Thesis, Montpellier, 2016. http://www.theses.fr/2016MONTD055/document.
Повний текст джерелаThis thesis explores the relationship between ownership structure (cooperative versus investorowned), market strategies as well as financial performance and risk. It tackles three databases in three different sectors: (1) French SMEs, (2) French wine sector (3) and financial institutions in the USA, along with a comparative methodology using empirical data. It contributes to the existing literature through a transversal approach between marketing and finance, in the framework of cooperatives with significant samples of data.Results show that cooperatives have lower levels of financial performance (except thrifts) with lower financial risk (except credit unions) compared to investor-owned firms; cooperatives have higher level of capitalization allowing them to face economic crises. Moreover, cooperatives adopt different market strategies. Research in the wine sector show that cooperatives tend to choose collective branding whereas investor-owned firms prefer private brands. As for financial institutions, business lines and relationship lending approaches vary according to ownership structures. In terms of the relationship between ownership structure and market strategies on one hand, and financial performance and risk on the other, results show that market strategies can affect financial performance while the main factor reducing the risk is cooperative structure
Said, Emilio. "Market Impact in Systematic Trading and Option Pricing." Thesis, université Paris-Saclay, 2020. http://www.theses.fr/2020UPASC030.
Повний текст джерелаThe main objective of this thesis is to understand the various aspects of market impact. It consists of four chapters in which the market impact is studied in different contexts and at different scales. The first chapter presents an empirical study of the market impact of limit orders on European equity markets. In the second chapter, we have extended the methodology presented for the equity markets to the options markets. This empirical study has shown that our definition of an options metaorder allows us to retrieve all the results highlighted on the equity markets. The third chapter focuses on market impact in the context of option pricing. This chapter is based on previous works of option pricing with market impact and attempts to bring a microstructure component to pricing option theory by proposing a perturbation theory of market impact during the re-hedging process. We explore in the fourth chapter a fairly simple model for the relaxation of metaorders. The relaxation of metaorders is treated in this part as an informational process which is transmitted to the market. Thus, starting from the starting point that at the end of the execution of a metaorder the information carried by this one is maximum, we propose an interpretation of the relaxation phenomenon as being the result of the degradation of this information at the expense of outside market noise

Повний текст джерелаSir Isaac Newton, who is one of the most influential physicist and mathematician of all time, after he suffered huge losses in tulip market said: “I can calculate the motions of heavenly bodies, but not the madness of people.” Financial markets are full of uncertainties. The movement and volatility in stock prices has been the focus of attention for scholars all the time. Over the last decades, financial markets gain influence both at people’s life and country’s economics as a result of technological advances, financial liberalization, and ongoing international trade. On one hand, participant’s property and investor’s market performance are impacted by price fluctuation. On the other hand, the development of national economic is closely interrelated to the stability of financial markets. In this effect, the understanding of investors’ designing making and how it affect the market price movement is of vital interest to both researchers and economic policy market. Experimental Finance has already become a well-established field, a fact that was recognized by the attribution of the Nobel Prize in Economics to Vernon Smith in 2002 who’s most significant work was concerned with market mechanisms and tests of different auction forms. However so far the major part of experimental work in Finance has considered (including Vernon Smith) human rationality and the ability of markets to find the proper price close to an equilibrium setting.

Повний текст джерелаWomen's participation in the labour force doesn't depend only on economic variables such as women' wage and family incom e. In fact we always have to take into account the impact of child care modes on this participation. For this reason, the presence of relatives in the household, who constitute a potential source for child care, has also an affect on woman's decision to participate in the labour force. Considering the impact of female participation on the labour market , we find that the increase in the number of women in the labour force has a negative effect on the wage level of younger workers

Повний текст джерелаThis thesis analyses the relationships between forms of flexibility and types of security. Firstly, a historical perspective emphasises the consecration of a general and deliberate movement aiming to enhance worker security in the aftermath of the Second World War in several industrialised countries. We show the emergence since the middle of the 1970s of a general trend toward greater flexibility that depends on labour market institutional settings. Secondly, two forms of flexible employment are analysed according to security/insecurity types: temporary employment and part-time work. Business cycle and institutional factors are considered within a panel data analysis of several European countries from the middle of the 1980s. Temporary employment and part-time work are a mean to adjust employment level to business cycle. Several institutional factors aiming to secure workers influence flexible employment. From a microeconomic point of view, we turn to econometric qualitative data analysis with the European Social Survey covering 18 countries. We evidence that temporary employment and part-time work, especially when this latter is constrained, accumulate several sociodemographic and professional factors that are unfavourable to their security. Several decompositions allow us to show the preponderant dimension of gender in the relationship between flexibility and security

Повний текст джерелаThis thesis is devoted to the study of price formation on financial markets, in particular when these are composed of a large number of agents. We start by the empirical study of an emergent market -- the bitcoin -- in order to better understand how individual actions impact prices -- a phenomenon known as « market impact ». We then develop a theoretical model based on the concept of heterogeneous agents, that allows to reproduce the empirical observations of a concave impact in a market that remains non-manipulable. The heterogeneous agents framework allows us to revisit the concepts of supply and demand in a dynamic context, to better understand how the choice of a particular market mechanism can impact liquidity, and to lay some grounds for a realistic market simulator. By studying several bubbles and crashes that happened on the bitcoin market, we finally show how relevant microstructure effects can be, in particular for understanding the occurrence of extreme phenomena

Повний текст джерелаFinancial markets are subjected daily to the diffusion of economic indicators and their forecasts by public institutions and even private ones. These annoncements can be scheduled or unscheduled. The scheduled announcements are organized according to a specific calendar and known in advance by all operators. These news such as activity indicators, credit, export or sentiments’ surveys, are published monthly or quarterly by specialized agencies to all operators in real time. Our thesis contributes to diferent literatures and aims to thoroughly analyze the three phases of the diffusion process of new information on financial markets : anticipation of the announcement before its publication, interest that arouse its publication and impact of its publication on market dynamics. The aim of the first chapter is to investigate heterogeneity in macroeconomic news forecasts using disaggregate data of monthly expectation surveys conducted by Bloomberg on macroeconomic indicators from January 1999 to February 2013. The second chapter examines the impact of surprises associated with monthly macroeconomic news releases on Treasury-bond returns, by paying particular attention to the moment at which the information is published in the month. In the third chapter we examine the intraday effects of surprises from scheduled and unscheduled announcements on six major exchange rate returns (jumps) using an extension of the standard Tobit model with heteroskedastic and asymmetric errors

Повний текст джерелаThe first chapter of this thesis investigates the relationship between Information and Communication Technologies (ICT) and productivity within 8 OECD countries. It aims at providing explanations for the coexistence of this strong technological evolution together with the absence of break in the productivity trend during the last decades. Our results suggest that there is a clearly identifiable positive relationship between computerization and technical progress, while ICT diffusion negatively affects pure efficiency changes. Our findings support that the economies under consideration are still in a phase of adaptation.The second chapter analyses the role of ICT on the job market polarization. Using data for 8 industrialized economies, our results show a significant contribution of ICT on polarization dynamics with some differences between countries and industries. We also find evidence that diffusion of ICT is initially accompanied by a Skill Bias Technological Change (SBTC), then contributing to job market polarization. Finally, our findings highlight a progressive weakening of the positive link between ICT diffusion and the increasing demand for high-skilled workers over time.The third chapter evaluates the risk of job destructions induced by computer technology in Japan. Relying on recent methodology, we found evidence that approximatively 55% of jobs are susceptible to be carried by computer capital in the next years. We also show that thereis no significant difference on the basis of gender. On the contrary, non-regular jobs (those that concern temporary and part-time workers) are more vulnerable to computer technology diffusion than the others

Повний текст джерелаThe main objective of this work is to contribute to the debate initiated by Roll (1977) and Basu (1977) since more than thirty years on disability of the CAPM to explain the financial assets pricing. This study focuses specifically on the ability of the suggested ratio of dividend yield to be an independent risk proxy beta. It tests the ability of a value strategy based on the popular "dividend yield" effect to achieve abnormal performance. The results show that the good performances of the Dow 10 are not attributable to its ability to select stocks with high scores or his ability to anticipate market movements. Moreover, being in competition with the regression of Litzenberger and Ramaswamy (1979) and a model replicating the methodology Fama and French (1993), the Sharpe‟s asset pricing model stands out as the best model for forecasting returns. To show that the beta captures the dividend yield effect, we propose a new formulation of the CAPM. We propose a decomposition of beta into two risk factors: a systematic basis risk and a risk factor related to dividend yield. Overall, the efficient market hypothesis seems to be verified. Indeed, the application of our model improves the explanatory power of 3% of the CAPM and our regression coefficients are significant at 1%. The “dividend yield” effect is a risk factor already captured by the Sharpe‟s regression

Повний текст джерелаThe aim of this CIFRE thesis, realized with the market research institute BVA in collaboration with the automobile manufacturer Renault, is to build a model in order to measure the impact of media investments of several channels (television, outdoor, etc.) on the brands’ market shares, taking into account the competition and the potential cross effects and synergies between brands, as well as accounting for the price, the regulatory context (scrapping incentive), and the lagged effects of advertising. We have drawn from marketing and statistical literatures to develop, compare and interpret several models which respect the unit sum constraint of market shares. A practical application to the French automobile market is presented, for which it is shown that brands’ market shares are more or less sensitive to advertising investments made in each channel, and that synergies between brands exist

Повний текст джерелаThis thesis investigates the effects of one or multiples exogeneous shocks in stock market. More precisely, we are interested in the impact of a news shock on the behaviour of stock prices,bubbles, price volatility, transactions volume and analyst’s forecasts. To tackle this question,we depicted the subject in three axes. The first essay presents an empirical analysis that tests the effects of an expected shock - the Brexit vote announcement - on the long-run market performance of British listed firms and European listed firms. Our results show that the Brexit announcement affected negatively the long-run market performance over a 12 months’ horizon of UK firms in any of their business activities and European non-British firms having most oftheir business activities within the British area. In the second paper, we investigate experimentally the effects of expected and unexpected shock on an asset’s fundamental value.Our findings show that shocks have a negative effect on the price deviation from the fundamental value and a positive effect on the differences of opinion regardless of the type ofshocks - expected or unexpected - and regardless of the direction - upward or downward. The third paper focuses on the effects of unexpected multiple shocks in an experimental market.Our main findings are as follows: Multiple downward shocks reduce transactions volume andprice volatility, while multiple upward shocks have no effect on trading volume and increase price volatility. Finally, we observe, only in markets without shocks, a positive link between the volume of transactions and the differences of opinion

Повний текст джерелаThe relationship between financial development and economic growth has attracted particular attention in the economic literature in recent decades. Our research tries to assess the effects of liberalization of the financial system in Morocco on economic growth. The results show the need to put in place mechanisms to optimize and strengthen the positive impact of financial liberalization on the real economy. Thus defined, financial liberalization is seen in some developed countries during the 70s, sometimes ideologically as a strategy developed by the authorities concerned, sometimes as a constraint imposed by the market. Its evolution has intensified and spread to almost all developing countries during the 80s, with the institution of Structural Adjustment Programmes (SAP) and the outbreak of the globalization process. Recognizing the important role that the financial sector can play in boosting national economic activity, the Moroccan authorities have launched, since the early 90s, a continuous and uninterrupted process of reform, in particular through the lifting of constraints on the Moroccan bank system, on the development of capital market liberalization and the way to finance the Treasury. The aim is to develop and improve the face of the financial sector to make it an efficient instrument of mobilization and development of savings and its channeling towards the financing of investment for strong, sustainable growth, generating wealth and reducing unemployment and poverty

Повний текст джерелаBy definition, temporary workers are only bound by temporary contracts, yet we find that, between 1998 and 2002, 165 000 people have been employed as temporary workers each year for more than six months.In this research, we raise the question of the existence of these long term temporary workers through the presumption that their existence is linked to the state of the wage continuum that is gradually losing its place as the organizing principle of French society. Through a qualitative survey, we highlight the importance of several elements. First, trust is actively maintained between the temporary worker and the agency. Secondly, the long-term temporary workers rely on family or estate to secure their position. In addition to these prerequisites, we find that, when sent on a mission, temporary workers benefit from the weakening of the security feeling that permanent contracts used to provide.Good reasons behind long term-temporary work are related to the fear of unemployment and to the resignation of the trade-off between political and economic spheres that gave birth to the insurance-State. The security of steady employment is now being questioned while it is needed to obtain loans necessary to purchase home ownership. At the same time, the latter seems to take its place as guarantor and allows home owners to deviate from the continuum wage without repercussion while participating in its weakening
