Essais sur les frictions financières dans les modèles d'équilibre général dynamique

Cette thèse examine les effets des imperfections des marchés financiers sur la macroéconomie. Plus particulièrement, elle se penche sur les conséquences de la faillite dans les contrats financiers dans une perspective d'équilibre général dynamique. Le premier papier construit un modèle qui utilise l'avantage comparatif des banques dans la gestion des situations de détresse financière pour expliquer le choix des firmes entre les prêts bancaires et les prêts du marché financier. Le modèle réussit à expliquer pourquoi les firmes plus petites préfèrent le financement bancaire et pourquoi les prêts bancaires sont plus répandus en Europe. Le premier fait est expliqué par le lien négatif entre la valeur nette de l'entreprise et la probabilité de faire faillite. Le deuxième fait s'explique par le coût fixe d'émission de bons plus élevé en Europe. Le deuxième papier examine l'interaction entre les contraintes de financement affectant les ménages et les firmes. Une interaction positive pourrait amplifier et augmenter la persistance de l'effet d'un choc agrégé sur l'économie. Je construis un nouveau modèle qui contient des primes de financement externes pour les firmes et les ménages. Dans le modèle de base avec prix et salaires flexibles, j'obtiens une faible interaction négative entre les coûts de financement des firmes et des ménages. Le facteur clé qui explique ce résultat est l'effet du changement contre cyclique du coût de financement des ménages sur leur offre de travail et leur demande de prêts. Dans une période d'expansion, cet effet augmente les taux d'intérêt, réduit l'investissement et augmente le coût de financement des entreprises. Le troisième papier ajoute les contraintes de financement des banques dans un modèle macroéconomiques avec des prêts hypothécaires et des fluctuations dans les prix de l'immobilier. Les banques dans le modèle ne peuvent pas complètement diversifier leurs prêts, ce qui génère un lien entre les risques de faillite des ménages et des banques. Il y a deux effets contraires des cycles économiques qui affectent la prime de financement externe de la banque. Premièrement, il y a un lien positif entre le risque de faillite des banques et des emprunteurs qui contribue à rendre le coût de financement externe des banques contre cyclique. Deuxiément, le lissage de la consommation par les ménages rend la proportion de financement externe des banques pro cyclique, ce qui tend à rendre le coût de financement bancaire pro cyclique. En combinant ces deux effets, le modèle peut reproduire des profits bancaires et des ratios d'endettement bancaires pro cycliques comme dans les données, mais pour des chocs non-financiers les frictions de financement bancaire dans le modèle n'ont pas un effet quantitativement significatif sur les principales variables agrégées comme la consommation ou l'investissement.

A model of dynamic liquidity contracts

I study long-term financial contracts between lenders and borrowers in the absence of perfect enforceability and when both parties are credit constrained. Borrowers repeatedly have projects to undertake and need external financing. Lenders can commit to contractual agreements whereas borrowers can renege any period. I show that equilibrium contracts feature interesting dynamics: the economy exhibits efficient investment cycles; absence of perfect enforcement and shortage of capital skew the cycles toward states of liquidity drought; credit is rationed if either the lender has too little capital or if the borrower has too little collateral. This paper's technical contribution is its demonstration of the existence and characterization of financial contracts that are solutions to a non-convex dynamic programming problem.

Selection of funding schemes by a borrowing decision model: a Hong Kong case study

In financial decision-making, a number of mathematical models have been developed for financial management in construction. However, optimizing both qualitative and quantitative factors and the semi-structured nature of construction finance optimization problems are key challenges in solving construction finance decisions. The selection of funding schemes by a modified construction loan acquisition model is solved by an adaptive genetic algorithm (AGA) approach. The basic objectives of the model are to optimize the loan and to minimize the interest payments for all projects. Multiple projects being undertaken by a medium-size construction firm in Hong Kong were used as a real case study to demonstrate the application of the model to the borrowing decision problems. A compromise monthly borrowing schedule was finally achieved. The results indicate that Small and Medium Enterprise (SME) Loan Guarantee Scheme (SGS) was first identified as the source of external financing. Selection of sources of funding can then be made to avoid the possibility of financial problems in the firm by classifying qualitative factors into external, interactive and internal types and taking additional qualitative factors including sovereignty, credit ability and networking into consideration. Thus a more accurate, objective and reliable borrowing decision can be provided for the decision-maker to analyse the financial options.

International financial reporting standards (IFRS) as a change agent in Ukraine

This paper aims to examine the perception of key actors regarding the costs and benefits that result from adopting International Financial Reporting Standards (IFRS) in Ukraine. Authors showed that IFRS implementation impacts on internal reporting quality, the relationship with customers, creditors and shareholders, the access to international markets and external financing. They also indicated that financial managers have serious concerns about implementation costs related to the introduction of IFRS. These costs relate to training, instruction on IFRS adoption and translation of current IFRS, changes in software systems, double purpose accounting and deadlines for IFRS adoption and consulting services.

Latin America major player in the international financial markets, agony and ecstasy

This study deals with the complex relationship between the International Financial Markets (IFMs) and the countries of the Latin America Group, emphasizing the entrance and the exit conditions for these countries in the last two indebtedness cycles - 1967/1982 and 1990/1994. Finally, it makes some considerations about the consequences of these Latin America countries of being linking economic policies to the external financing abtained in the IFMs.

Gestão de recursos externos em projetos na área social: o caso do Projeto de Serviços Básicos de Saúde no Nordeste - PNE I

The following paper analyses the managerial and administrative aspects of a project named Projeto de Serviços Básicos de Saúde no Nordeste (PNE I) - initiated in the 80¿s and has been funded by the International Development and Reconstruction Bank (IDRB) ¿ for the construction of a series of lessons and recommendations to be observed along the formulation, implementation and assessment of projects performed under external financing. During the Project time the most important and deep changes and innovations have occurred involving the national politics for health, which have been mostly decisive at directing the Project, specially concerning the organization of services with emphasis to the process of decentralization as well as the participation of the organized society as a tool of social control. The expectations towards the publicizing and the dissemination of the paper presented are laid upon the warranty that the recommendations hereby given shall, effectively, contribute for the decrease of unwanted results and for the magnification of variables to be considered in projects with the scope and characteristics similar to PNE I.

Balance of payments dominance: its implications for macroeconomic policy

This paper defines “balance of payments dominance” as a macroeconomic regime in which the short-term macroeconomic dynamics is essentially determined by external shocks, positive or negative. It argues that this is the predominant regime in emerging and developing countries. Trade shocks play an important role but the major procyclical shocks are associated with boom-bust cycles in external financing. Policy challenges are associated not only with the management of such shocks but also with the need to enhance the space for countercyclical macroeconomic policies, as boom-bust cycles tend to pressure macroeconomic policies to behave in a procyclical way. Under these conditions, the best bet is to design policies to reduce external vulnerabilities through a mix of administered exchange rate policies, very active foreign exchange reserve management, reduced reliance on external borrowing, and macroprudential regulations, including those directly affecting capital flows. Countercyclical fiscal policy can also play a role but face strong economic and political economy challenges.
