Résumé :

The banking literature following Diamond and Dybvig [Journal of Political Economy 85, 191–206 (1983)] has assumed that all depositors are ex ante identical. This paper relaxes this assumption by introducing two types of agents. Whereas some agents are uncertain about their liquidity needs at the time they deposit in banks, other agents know exactly at what time they will want to withdraw their funds. Agents who know ex ante that they will want to withdraw in the short term will tend to disrupt the ability of a bank to serve customers who are uncertain about their timing of withdrawal. An adverse selection problem arises, where short-term deposits have the incentive to join the financial system and limit, or completely do away with, banks' liquidity provision service. On the other hand, potentially beneficial long-term funds will not be deposited in banks. Further, when unpredicted short-term withdrawal needs are sufficiently high, bank reserves are exhausted, and long-term investments need to be disrupted, causing a banking crisis.

Résumé :

We consider a model of contagion in financial networks recently introduced in Gai, P. and Kapadia, S. [Contagion in financial networks, Proc. R. Soc. A466(2120) (2010) 2401–2423], and we characterize the effect of a few features empirically observed in real networks on the stability of the system. Notably, we consider the effect of heterogeneous degree distributions, heterogeneous balance sheet size and degree correlations between banks. We study the probability of contagion conditional on the failure of a random bank, the most connected bank and the biggest bank, and we consider the effect of targeted policies aimed at increasing the capital requirements of a few banks with high connectivity or big balance sheets. Networks with heterogeneous degree distributions are shown to be more resilient to contagion triggered by the failure of a random bank, but more fragile with respect to contagion triggered by the failure of highly connected nodes. A power law distribution of balance sheet size is shown to induce an inefficient diversification that makes the system more prone to contagion events. A targeted policy aimed at reinforcing the stability of the biggest banks is shown to improve the stability of the system in the regime of high average degree. Finally, disassortative mixing, such as that observed in real banking networks, is shown to enhance the stability of the system.

Résumé :

Abstract Effective corporate governance is fundamental to the correct operation of the banking sector. This study examines corporate governance in terms of the effects of different combinations of institutional investors on the performance of Portuguese banks. Effects based on kind (e.g. type of institutional investor) and degree (e.g. institutional investor experience) are considered. The results of a crisp-set qualitative comparative analysis (csQCA) show that the simultaneous presence of banks and corporations as shareholders, and non-presence of financial companies can positively affect banks’ return on average assets (ROAA) and return on average equity (ROAE). This research provides a wider picture of possible impacts in terms of banks’ performance when there are different types of institutional owners. Lastly, the results are particularly relevant for the supervision protocols developed by the Bank of Portugal and the European Central Bank, in situations of changes of banks’ shareholders.

Résumé :

Given the background of financial disintermediation and interest rate marketization, the assets of China’s commercial banks can be divided into traditional credit assets, whose rates of return are controlled by the supervision department, and financial assets, whose rates of return fluctuate according to market conditions. Direct financing enterprises are mainly state-owned enterprises with a good reputation, endorsed by the government, and they finance using the financial assets of commercial banks. Indirect financing enterprises are mainly private enterprises, which finance using credit assets. By introducing a financial intermediary sector with a balance sheet into dynamic stochastic general equilibrium (DSGE) model, our model endogenously determines the leverage ratio and the ratio of the two assets of the bank. Model results show that the impact from the volatility of financial markets and other exogenous shocks can affect the banks’ asset proportions of the two asset types, asymmetrically affecting the production scale of enterprises with two types of financing. Further, the bank’s leverage ratio changes will have a magnifying effect on economic fluctuations.

Résumé :

This article examines the role of bank-level characteristics in determining the nature of interest rate pass-through from monetary policy rates to commercial banks’ lending rates in Pakistan. Several bank-level factors, namely market size, liquidity, capitalisation, profitability, and competition level, were used in analysing the pass-through mechanism. This study utilised a dynamic heterogeneous panel technique, namely the Pooled Mean Group (PMG) estimation for the sample of 12 private commercial banks, over the time span 2003:Q2 to 2015:Q4. Banks of smaller size, large capital, and higher liquidity were significantly affecting the interest rate pass-through procedure. Thus, to improve monetary policy’s transmission mechanism, Pakistan’s central bank should limit bank capitalisation and draw out excess liquidity from the banking sector.

Résumé :

We study banks' incentive to pool assets of heterogeneous quality when investors evaluate pools by extrapolating from limited sampling. Pooling assets of heterogeneous quality induces dispersion in investors' valuations without affecting their average. Prices are determined by market clearing assuming that investors can neither borrow nor short‐sell. A monopolistic bank has the incentive to create heterogeneous bundles only when investors have enough money. When the number of banks is sufficiently large, oligopolistic banks choose extremely heterogeneous bundles, even when investors have little money and even if this turns out to be collectively detrimental to the banks. If, in addition, banks can originate low quality assets, even at a cost, this collective inefficiency is exacerbated and pure welfare losses arise. Robustness to the presence of rational investors and to the possibility of short‐selling is discussed.

Résumé :

We examine the welfare implications of two types of central-bank transparency: the publication of the information underlying the central bank's decision (decision transparency) and the release of the information that the central bank observes afterwards (postdecision transparency). Decision transparency does not make the public better informed in equilibrium. Even so, it may be socially desirable because it eliminates harmful equilibria. Postdecision transparency has ambiguous effects. It reduces output variance and the distortions stemming from heterogeneous information. In this sense, it can be used as a substitute for monetary policy. However, postdecision transparency generally raises the variance of inflation. We argue that a conflict of interests may arise between society and the central bank with regard to transparency.

Résumé :

Purpose This paper aims to examine the heterogeneity of preferences of mortgage borrowers of Russian state-owned suppliers of residential housing mortgages. Design/methodology/approach Analysis takes into account the underwriting process and the choice of contract terms of all loans originated from 2008 to 2012. The data set contains demographic and financial characteristics for all applications, loan terms and the performance information for all issued loans by one regional bank which operates government mortgage programs. The paper uses a multistep semiparametric approach to estimate the determinants of bank and borrower choice controlling for possible heterogeneity of preferences, sample selection and endogeneity of contract terms. Findings The study found that the demand of low-income households who are unable to afford to improve the housing conditions by other instruments than government mortgage is less elastic according to the change both in interest rate and maturity compared with higher-income households. Social implications Given lower elasticities of the demand, the low-income group of borrowers has higher potential cost of loan and is usually rejected by commercial banks. The presence of the Agency of Housing Mortgage Lending special programs with subsidized interest rate for special constrained categories (young families, teachers, researchers etc.) widens the access for housing conditions’ improvements as a part of housing affordability government program. Originality/value The main contribution to the literature is modeling choice of contract terms as interdependent by the structural system of simultaneous equations with heterogeneous marginal effects.

Résumé :

Lo scopo della presente tesi è far luce sul ruolo del mercato interbancario nella trasmissione di shock idiosincratici verso l’economia reale nel suo complesso. Maggiore attenzione è spesa nello studio di shock che nascono dal lato dell’offerta di credito. Il modello utilizzato è composto da un continuo di famiglie identiche e da una massa di imprenditori atomistici. In particolare, gli imprenditori sono di due tipi, uno rischioso e uno sicuro. Abbiamo costruito un modello DSGE che considera un sistema finanziario stilizzato, con un mercato interbancario con due intermediari. Una banca può raccogliere una quantità limitata di depositi dalle famiglie, ed è quindi spinta a raccogliere maggiori risorse sul mercato interbancario. Poiché i tassi di interesse sui prestiti riflettono la rischiosità dei due imprenditori, il tasso più alto dovuto dagli imprenditori rischiosi permette alla banca che prende a prestito sull’interbancario di essere sempre profittevole, permettendo così all’interbancario di verificarsi.
In the present paper we aim at shedding some light on the role played by the interbank market in the transmission of idiosyncratic shocks hitting single institutions to the whole system and the real economy. We focus, in particular, on shocks to the supply side of credit. We analyse an economy populated by a continuum of identical households, and a mass of atomistic entrepreneurs. In particular, entrepreneurs are of two types, one risky and one safe. We set up a DSGE model representing a simple economy featuring a stylised financial system, with two intermediaries, and an interbank market. One bank faces an exogeneous constraint on the aggregate amount of deposits it can collect. It can overcome its liquidity constraint by borrowing additional financial resources from the unconstrained bank on the interbank market. Since interest rates on loans reflect the relative riskyness of the two types of entrepreneurs, for each unit of borrowed money, the borrower bank is able to realise higher profits than the lender bank, hence the scope for mutually profitable trade on the interbank market. The second chapter of my thesis focused on two aspects that have not been already properly inspected, in the contribution offered by economists in the evaluation of economic effects brought by the recent SARS-CoV-19 pandemic. Specifically, as far as we know, the economic models tipically used to study the Corona-virus effects did not take into account i) the possibility to provide workers forced into lockdown with a subsidy, in order to mitigate the economic loss that comes along with the lockdown, and ii) the different levels of people's compliance to the lockdown policy and how to influence it. The aim of this paper is to shed some light on these two aspects. We try to evaluate the effectiveness of a common lockdown policy combined with a subsidy in influencing the behaviour of people in respecting the confinement.

Résumé :

Cette thèse contribue au débat sur les politiques de ciblage d’inflation et de transparence des banques centrales en présentant notamment trois essais théoriques et empiriques sur le sujet. Dans le premier essai, nous étudions théoriquement les conditions sous lesquelles il serait optimal pour une banque centrale d’adopter explicitement un régime de ciblage d’inflation. Nous proposons un nouveau cadre théorique qui combine les deux principales raisons avancées dans la littérature pour expliquer les effets réels à court terme de la politique monétaire et qui sont d’une part, la présence d’informations hétérogènes entre les agents économiques (Phelps, 1970 ; Lucas, 1972), et d’autre part, la rigidité des salaires ou des prix (Taylor, 1980 ; Calvo, 1983). Nous analysons ensuite notre problématique dans ce nouveau cadre en considérant l’interaction entre le degré de rigidité des prix, et le degré de complémentarités stratégiques dans la fixation de prix des firmes. Nos résultats montrent que l’adoption d’un régime de ciblage d’inflation dépend fortement de l’importance relative des paramètres du modèle. En particulier, nous montrons que le ciblage d’inflation devrait être toujours adopté lorsque les complémentarités stratégiques sont faibles, alors que dans le cas contraire, il est optimal uniquement lorsque les prix sont assez rigides et que la banque centrale détient des informations suffisamment précises sur les fondamentaux de l’économie. Dans le second essai, nous utilisons la macroéconomie expérimentale afin d’évaluer dans quelle mesure l’annonce de la cible d’inflation est pertinente dans un cadre de ciblage de l’inflation. Nos résultats montrent que lorsque la banque centrale ne se soucie que de la stabilisation de l’inflation, l’annonce de la cible d’inflation n’apporte pas de gain supplémentaire en termes de performances macro-économiques, par rapport à une politique monétaire active (type règle de Taylor). Cependant, si la banque centrale intègre également la stabilisation de l’activité économique dans ses objectifs, la communication de la cible contribue à réduire la volatilité de l’inflation, du taux d’intérêt, et de l’écart de production, bien que leurs niveaux moyens ne soient pas affectés. Ce résultat fournit ainsi une justification pour l’adoption d’un régime de ciblage flexible d’inflation par la majorité des pays ciblant l’inflation. Enfin dans le troisième essai, nous appliquons une analyse transversale ainsi que la technique des variables instrumentales, afin d’analyser les effets de la transparence des banques centrales sur les résultats macroéconomiques dans les pays émergents. Nous construisons un nouvel indice de transparence qui combine certains aspects de l’indice de transparence globale d’Eijffinger et Geraats (2006), avec ceux de l’indice de transparence sur le comité de politique monétaire de Hayo et Mazhar (2011). Nous analysons ensuite le rôle individuel de chaque composante du nouvel indice en termes de réduction du niveau de l’inflation et de sa volatilité, ainsi que de la volatilité du produit. Contrairement à la littérature antérieure, nous trouvons que le nouvel indice de transparence ainsi que ses aspects économique, politique, procédurale et de transparence sur la politique monétaire impactent négativement le niveau moyen de l’inflation, mais pas sa volatilité dans ces pays. L’unique composante du nouvel indice qui permet de réduire à la fois la volatilité de l’inflation et celle de la production est la transparence opérationnelle. Ces résultats s’avèrent robustes aux différentes spécifications de modèles économétriques utilisés dans cet essai
This dissertation contributes to the debate on inflation targeting and central bantransparency by presenting three theoretical and empirical essays on the topic. In the first essay, we theoretically investigate the conditions under which it would be optimal for a central bank to explicitly adopt an inflation targeting regime. We propose a new theoretical framework that combines the two main frictions put forward in the literature to explain the real short run effects of monetary policy that is, heterogeneous information among agents (Phelps, 1970; Lucas, 1972), and wage or price rigidities (Taylor, 1980; Calvo, 1983). We then analyze our issue in this new framework by considering the interaction between the degree of price stickiness, and the degree of strategic complementarities in firms’ price setting. Our results show that adopting an inflation targeting regime crucially depends on the relative importance of the model’s parameters. In particular, we show that inflation targeting should always be adopted when strategic complementarities are low, while in the opposite case, it is optimal only if prices are sticky enough and the central bank holds sufficiently accurate information on the fundamentals of the economy. In the second essay, we use experimental macroeconomics to evaluate to what extent communication of the inflation target is relevant in an inflation targeting framework. Our results show that first, when the central bank only cares about inflation stabilization, announcing the inflation target does not make a difference in terms of macroeconomic performance compared to a standard active monetary policy. However, if the central bank also cares about the stabilization of the economic activity, communicating the target helps to reduce the volatility of inflation, interest rate, and output gap although their average levels are not affected. This finding provides a rationale for the adoption of flexible inflation targeting by the majority of inflation targeting countries. In the third essay, using a cross-sectional analysis and instrumental variables technique, we analyze the impact of central bank transparency on macroeconomic outcomes in emerging economies. We build a new index of transparency that combines some aspects of the overall Eijffinger and Geraats (2006) transparency index, with those of monetary policy committee transparency developed in Hayo and Mazhar (2011). We then analyze the individual role of each component of the new index in mitigating inflation and its volatility, as well as output volatility. By contrast to the previous literature, we interestingly find that the overall new index of transparency as well as its political, economic, procedural, and policy aspects negatively impact the average level of inflation, but not its volatility in these countries. The unique component of the new index that reduces the volatility of both inflation and output is operational transparency, and these results are robust to different econometric and instruments setting specifications

Résumé :

Observations of modern carbonate depositional environments and their accompanying depositional models have been used for decades in the reconstruction and interpretation of ancient carbonate depositional environments and stratigraphic successions. While these Holocene models are necessary for interpreting their more ancient counterparts, they inherently exclude important factors related to the erosion, diagenesis, and ultimate preservation of sediments and sedimentary structures that are ubiquitous in shallow marine carbonate environments. Andros Island, Bahamas is an ideal location to examine the validity of Holocene conceptual models, where geologically young (Late Pleistocene) limestones can be studied immediately adjacent to their well-documented modern equivalents. For this study, two 3D ground-penetrating radar (GPR) datasets (200 MHz and 400 MHz) were collected at a schoolyard in northwest Andros. These surveys reveal the geometries and internal characteristics of a peloidal-oolitic sand wave and tidal channel in unprecedented detail. These two prominent features are underlain by low-energy lagoonal wackestones and packstones, and are bordered laterally to the northwest by wackestones-packstones intermixed with thin sheets of peloidaloolitic grainstone. A deeper radar surface is observed at approximately 6 m depth dipping gently to the west, and is interpreted to be a karstified exposure surface delineating the base of a complete depositional sequence. Interpretation of the 3D radar volumes is enhanced and constrained by data from three cores drilled through the crest and toe of the sand wave, and through the tidal channel. This study is the first of its kind to capture the complex heterogeneity of a carbonate depositional package in three dimensions, where various depositional environments, sedimentary structures, and textures (mudstone to grainstone) have been preserved within a small volume.The results from this study suggest that the degree of vertical and lateral heterogeneity in preserved carbonate successions is often more complex than what can be observed in modern depositional environments, where sediments can generally only be observed in two dimensions, at an instant in time. Data from this study demonstrate the value of using two overlapping GPR datasets at differing resolutions to image the internal characteristics of a complete carbonate depositional package in three dimensions. From these datasets, a depositional model similar to other Holocene and Pleistocene carbonate depositional models is derived.

There are several economic situations in which an agent’s willingness to take a given action is increasing in the amount of other agents who are expected to do the same. These kind of strategic complementarities often lead to multiple equilibria. Moreover, the outcome achieved by agents’ decentralized decisions may be inefficient, leaving room for policy interventions. This dissertation analyzes different environments in which coordination among individuals is a concern. The first chapter analyzes how information manipulation and disclosure affect coordination and welfare in a bank-run model. There is a financial regulator who cannot credibly commit to reveal the situation of the banking sector truthfully. The regulator observes banks’ idiosyncratic information (through a stress test, for example) and chooses whether to disclose it to the public or only to release a report on the health of the entire financial system. The aggregate report may be distorted at a cost – higher cost means higher credibility. Investors are aware of the regulator’s incentives to conceal bad news from the market, but manipulation may still be effective. If the regulator’s credibility is not too low, the disclosure policy is state-contingent and there is always a range of states in which there is information manipulation in equilibrium. If credibility is low enough, the regulator opts for full transparency, since opacity would trigger a systemic run no matter the state. In this case only the most solid banks survive. The level of credibility that maximizes welfare from an ex ante perspective is interior. The second and the third chapters study coordination problems in dynamic environments. The second chapter analyzes welfare in a setting where agents receive random opportunities to switch between two competing networks. It shows that whenever the intrinsically worst one prevails, this is efficient. In fact, a central planner would be even more inclined towards the worst option. Inefficient shifts to the intrinsically best network might occur in equilibrium. When there are two competing standards or networks of different qualities, if everyone were to opt for one of them at the same time, the efficient solution would be to choose the best one. However, when there are timing frictions and agents do not switch from one option to another all at once, the efficient solution differs from conventional wisdom. The third chapter analyzes a dynamic coordination problem with staggered decisions where agents are ex ante heterogeneous. We show there is a unique equilibrium, which is characterized by thresholds that determine the choices of each type of agent. Although payoffs are heterogeneous, the equilibrium features a lot of conformity in behavior. Equilibrium vii thresholds for different types of agents partially coincide as long as there exists a set of beliefs that would make this coincidence possible. However, the equilibrium strategies never fully coincide. Moreover, we show conformity is not inefficient. In the efficient solution, agents follow others even more often than in the decentralized equilibrium.
No estudo da economia, há diversas situações em que a propensão de um indivíduo a tomar determinada ação é crescente na quantidade de outras pessoas que este indivíduo acredita que tomarão a mesma ação. Esse tipo de complementaridade estratégica geralmente leva à existência de múltiplos equilíbrios. Além disso, o resultado atingido pelas decisões decentralizadas dos agentes pode ser ineficiente, deixando espaço para intervenções de política econômica. Esta tese estuda diferentes ambientes em que a coordenação entre indivíduos é importante. O primeiro capítulo analisa como a manipulação de informação e a divulgação de informação afetam a coordenação entre investidores e o bem-estar em um modelo de corridas bancárias. No modelo, há uma autoridade reguladora que não pode se comprometer a revelar a verdadeira situação do setor bancário. O regulador observa informações idiossincráticas dos bancos (através de um stress test, por exemplo) e escolhe se revela essa informação para o público ou se divulga somente um relatório agregado sobre a saúde do sistema financeiro como um todo. O relatório agregado pode ser distorcido a um custo – um custo mais elevado significa maior credibilidade do regulador. Os investidores estão cientes dos incentivos do regulador a esconder más notícias do mercado, mas a manipulação de informação pode, ainda assim, ser efetiva. Se a credibilidade do regulador não for muito baixa, a política de divulgação de informação é estado-contingente, e existe sempre um conjunto de estados em que há manipulação de informação em equilíbrio. Se a credibilidade for suficientemente baixa, porém, o regulador opta por transparência total dos resultados banco-específicos, caso em que somente os bancos mais sólidos sobrevivem. Uma política de opacidade levaria a uma crise bancária sistêmica, independentemente do estado. O nível de credibilidade que maximiza o bem-estar agregado do ponto de vista ex ante é interior. O segundo e o terceiro capítulos estudam problemas de coordenação dinâmicos. O segundo capítulo analisa o bem-estar em um ambiente em que agentes recebem oportunidades aleatórias para migrar entre duas redes. Os resultados mostram que sempre que a rede de pior qualidade (intrínseca) prevalece, isto é eficiente. Na verdade, um planejador central estaria ainda mais inclinado a escolher a rede de pior qualidade. Em equilíbrio, pode haver mudanças ineficientes que ampliem a rede de qualidade superior. Quando indivíduos escolhem entre dois padrões ou redes com níveis de qualidade diferentes, se todos os indivíduos fizessem escolhas simultâneas, a solução eficiente seria que todos adotassem a rede de melhor qualidade. No entanto, quando há fricções e os agentes tomam decisões escalonadas, a solução eficiente difere ix do senso comum. O terceiro capítulo analisa um problema de coordenação dinâmico com decisões escalonadas em que os agentes são heterogêneos ex ante. No modelo, existe um único equilíbrio, caracterizado por thresholds que determinam as escolhas para cada tipo de agente. Apesar da heterogeneidade nos payoffs, há bastante conformidade nas ações individuais em equilíbrio. Os thresholds de diferentes tipos de agentes coincidem parcialmente contanto que exista um conjunto de crenças arbitrário que justifique esta conformidade. No entanto, as estratégias de equilíbrio de diferentes tipos nunca coincidem totalmente. Além disso, a conformidade não é ineficiente. A solução eficiente apresentaria estratégias ainda mais similares para tipos distintos em comparação com o equilíbrio decentralizado.

Résumé :

Plane strain transient finite thermomechanical deformations of heat-conducting particulate composites comprised of circular tungsten particulates in nickel-iron matrix are analyzed using the finite element method to delineate the initiation and propagation of brittle/ductile failures by the nodal release technique. Each constituent and composites are modeled as strain hardening, strain-rate-hardening and thermally softening microporous materials. Values of material parameters of composites are derived by analyzing deformations of a representative volume element whose minimum dimensions are determined through numerical experiments. These values are found to be independent of sizes and random distributions of particulates, and are close to those obtained from either the rule of mixtures or micromechanics models. Brittle and ductile failures of composites are first studied by homogenizing their material properties; subsequently their ductile failure is analyzed by considering the microstructure. It is found that the continuously varying volume fraction of tungsten particulates strongly influences when and where adiabatic shear bands (ASB) initiate and their paths. Furthermore, an ASB initiates sooner in the composite than in either one of its constituents. We have studied the initiation and propagation of a brittle crack in a precracked plate deformed in plane strain tension, and a ductile crack in an infinitely long thin plate with a rather strong defect at its center and deformed in shear. The crack may propagate from the tungsten-rich region to nickel-iron-rich region or vice-a-versa. It is found that at the nominal strain-rate of 2000/s the brittle crack speed approaches Rayleigh's wave speed in the tungsten-plate, the nickel-iron-plate shatters after a small extension of the crack, and the composite plate does not shatter; the minimum nominal strain-rate for the nickel-iron-plate to shatter is 1130/s. The ductile crack speed from tungsten-rich to tungsten-poor regions is nearly one-tenth of that in the two homogeneous plates. The maximum speed of a ductile crack in tungsten and nickel-iron is found to be about 1.5 km/s. Meso and multiscale analyses have revealed that microstructural details strongly influence when and where ASBs initiate and their paths. ASB initiation criteria for particulate composites and their homogenized counterparts are different.

Résumé :

Synthetic antenna aperture (SAR) is a pulses focusing airborne radar which can achieve high resolution radar image. A number of image process algorithms have been developed for this kind of radar, but the calculation burden is still heavy. So the image processing of SAR is normally performed “off-line”.

The Fast Factorized Back Projection (FFBP) algorithm is considered as a computationally efficient algorithm for image formation in SAR, and several applications have been implemented which try to make the process “on-line”.

CELL Broadband Engine is one of the newest multi-core-processor jointly developed by Sony, Toshiba and IBM. CELL is good at parallel computation and floating point numbers, which all fit the demands of SAR image formation.

This thesis is going to implement FFBP algorithm on CELL Broadband Engine, and compare the results with pre-projects. In this project, we try to make it possible to perform SAR image formation in real-time.

Résumé :

Investment in fixed assets declined over the crisis period in all countries. We implement an econometric analysis to explore the differential impact of leverage and debt maturity structure on investment, finding that in crisis years (i) leverage exerts a strong and negative effect on investment, and (ii) firms with more long-term debt invest less. We uncover heterogeneous reactions to the crisis due to the level of debt and its maturity, sorting firms by country-specific and firm-specific characteristics. Firms which cut back most investment in crisis years (conditional on the level of leverage and maturity) are (i) small and (ii) located in Eurozone periphery countries. Factors that alleviate financial friction and shield investment include multiple bank relationships and the ability to generate internal resources (cash flow). We find no evidence of a positive nexus between cash and investment, and little evidence of a positive effect on investment of access to capital markets.

Résumé :

Abstract In the sociology of scientific knowledge and the sociology of translation, heterogeneous networks have been studied in terms of practices and so-called actor-networks. However, scientific practices are intellectually structured by codes. Cognitive structures interact and co-construct the organization of scholars and discourses into research programs, specialties, and disciplines. The intellectual organization of the sciences adds to and feeds back on the configurations of authors and texts. The social, textual, and cognitive sub-dynamics select upon each other asymmetrically. Selections can further be selected for stabilization along trajectories and then also be globalized—symbolically generalized—into regimes of expectations.

The empirical evidence is conducted by applying a Markov switching approach to daily AUD/USD exchange rate, intervention data of the Reserve Bank of Australia from 2006 to 2012. Our results are supporting both chartists and fundamentalist regimes. It is shown that the two regimes are persistent. However, Reserve Bank of Australia efforts to exert a stabilizing eﬀect of foreign exhange interventions, the result is inconclusive.

Résumé :

Credits are the one of the most important functions in bank management, because, from one side, thanks to a good credit policy a bank can earn money, but from the other side, in the case of weak or wrong credit policy the bank can make substantial losses. Therefore in the field of credit policy management, intelligent information systems can be very helpful, as it is a complex and heterogeneous field, needing complex management and decision-making procedures. There exist many technical solutions aimed at helping the decision-makers in this field, from “traditional” ones, as databases, to more sophisticated tools, as for example expert systems, the main aim of which is to perform the analysis of applications for a credit, thus helping to make proper credit decisions. Credit management is closely related to time, in other words, the temporal aspect of credit management can be very clearly seen. Therefore while building intelligent systems in this area, it would be recommended to take this temporal aspect into account. The article concentrates on the question of searching and choosing an intelligent computer tool which would fulfil the above mentioned requirements, the toll which would help to make necessary credit analyses, to make proper credit decisions, taking into account the temporal aspect of credit management. Two solutions are discussed: TAL language and active databases. Some exemplary credit management rules are encoded both in the TAL language and in the form of ECA rules. Both kinds of rules are analysed and discussed, as well as their advantages and disadvantages.

Texte intégral

Résumé :

This paper studies from an empirical and theoretical perspective the systemic and bank-level effects of imposing reserve requirements (RR) in foreign currency in an economy with a heavily dollarized financial system. The paper empirically characterizes banks responses to the RR carried out by the Peruvian Central Bank since 2008 with the objective of stabilizing the financial market and meeting its policy targets. The results suggest that the RR is effective in reducing the overall level of credit in the economy and that banks response in terms of credit and deposits is very heterogeneous depending on their ex ante preference for foreign funding ratio, i.e., the ratio of deposits in dollars to total loans. Motivated by the empirical insights, the paper builds a DSGE small-open-economy model with financial frictions à la Gertler-Karadi-Kiyotaki, where bank heterogeneity and financial dollarization are introduced to evaluate the effectiveness of the differential RR in reducing financial dollarization and improving financial resilience.

Texte intégral

Résumé :

We show that inflation expectations are heterogeneous and depend on past individual experiences. We propose a diagnostic expectations-augmented Kalman filter to represent consumers’ heterogeneous inflation expectations-formation process, where heterogeneity comes from an anchoring-to-the-past mechanism. We estimate the diagnosticity parameter that governs the inflation expectations-formation process and show that the model can replicate systematic differences in inflation expectations across cohorts in the US. We introduce this mechanism into a New Keynesian model and find that heterogeneous expectations anchor aggregate responses to the agents’ memory, making shocks more persistent. Central banks should be more active to prevent agents from remembering current shocks far into the future.

Texte intégral

Résumé :

Mesenteric pseudocyst (MP) is a rare heterogeneous group of intra-abdominal benign cystic lesions with different etiopathogenesis and clinically silent behaviours. These lesions are introduced as one of the entities based on the histological features of thick fibrous cyst walls, barren of the epithelial lining. Often, they present as expanding abdominal masses or are diagnosed incidentally in conventional radiological studies, exploratory laparotomies, or with symptoms of complications such as infection, torsion, or rupture. Surgical removal of the cyst, with or without resection of the affected intestinal segment, is the treatment of choice. Depending upon the size and location of the lesion and related complications, it can be managed by open surgical procedures or laparoscopic approach. Only a handful of 7 cases of traumatic mesenteric cysts have been reported yet in the vicinity of blunt abdominal trauma. We report a rare incidentally detected case of mesenteric pseudocyst (traumatic) in a male of early 20s with a history of blunt abdominal trauma 13 months back and for which serial abdominal exploratory laparotomies were performed. A brief review of the literature is provided, conforming to the rarity of the case. This case highlights the role of histomorphology in diagnosing a benign cystic entity with accuracy, that could be misdiagnosed as infectious granulomatous lesion.

Texte intégral

Résumé :

Economic theory is inconclusive regarding the effects of banning third-degree price discrimination under imperfect competition because they depend on how the competing firms rank their market segments. When, relative to uniform pricing, all competitors want higher prices in the same market segments, a ban on price discrimination will reduce profits and benefit some consumers at the expense of others. If, instead, some firms want to charge higher prices in segments where their competitors want to charge lower prices, price discrimination increases competition driving all prices down. In this case, forcing the firms to charge uniform prices can increase their profits and reduce consumer surplus. We use data on Colombian broadband subscriptions to estimate the demand for internet services. Estimated preferences and assumptions about competition are used to simulate a scenario in which firms lose their ability to price discriminate. Our results show large effects on consumer surplus and large effects on firms’ profits. Aggregate profits increase but the effects for individual firms are heterogeneous. The effects on consumer welfare vary by city. In most cities, a uniform price regime causes large welfare transfers from low-income households towards high-income households and in a few cities, prices in all segments rise. Poorer households respond to the increase in prices by subscribing to internet plans with slower download speed.
