I study the consequences of heterogeneity of skills for the design of an optimal unemployment insurance, using a principal-agent set-up with a risk neutral insurer and infinitely lived risk averse agents. Agents, who are characterised by different productivities or skills, are employed by firms...

The paper is an updated first performance evaluation study of the Polish pension funds operating from 1999. The unconditional performance evaluation models are used. It is shown that pension fund managers did produce additional value due to active management. Therefore, unsatisfactory overall...

In this paper we tackle the problem of the presence of negative average rate of returns in the computation of the performance of ethical mutual funds. The presence of these negative values raises problems both in the computation of the classical performance indicators and in DEA modeling. In...

The paper considers a modelin which limited liability causes an asset substitution problem for banks. The problem can at times become so severe that the current regulatory framework – based on a combination of effectively full deposit insurance, minimum capital requirements and prudential...

This paper provides a step-by-step hands on introduction to the techniques used in setting up and solving moral hazard problems with lotteries using Matlab. It uses a linear programming approach due to its relative simplicity and the high reliability of the available optimization algorithms.

Using panel data for 106 countries in 1971-1997, we estimate generalized least squares regressions to explain IMF lending as well as monetary and fiscal policies in the recipient countries. With respect to moral hazard, we find that a country's rate of monetary expansion and its government...

Much of the macro literature on the recent Asian crisis argues that a major cause was over borrowing and over investment encouraged by poor supervision and the resulting moral hazard problem. Surprisingly however there is little firm-level evidence to corroborate this. The present paper examines...

The purpose of the paper is to present a tractable model of an old topic which is becoming more important in macroeconomics: the link between financial structure and economic activity.

Collusion and soft budget constraint are two conspicuous phenomena in transition economies¡¯ banking system. Literature has separately investigated those two phenomena from theoretical point of views. However, the cross-point of both phenomena has been neglected in the research of banking...

In this paper, we prove that two firms can choose not to include a termination clause in their partnership contract, thus inducing a costly termination in case of failure of the joint project. This ex-post inefficiency induces partners to exert large non-contractible efforts (investments) to...
