The financial crisis of 2007-08 has underscored the importance of adverse selection in financial markets. This friction has been mostly neglected by macroeconomic models of financial frictions, however, which have focused almost exclusively on the effects of limited pledgeability. In this paper,...

We analyze the effects of income support on unemployment and welfare dynamics when stigma is attached to welfare provision. Stigma has been modeled in the literature as a cost of welfare participation; in this paper we analyze the effect of income support on unemployment and welfare dynamics by...

This paper shows that private information may be crucial in explaining the relationship between liquidity, investment and economic fluctuations. First, it defines liquidity in a way that is clearly connected to investment and output. Second, it models economies where privately informed...

Aim of this work is to evaluate the overall effect of social origins on secondary school track enrolment in Italy, Germany and Netherlands, allowing for consistent cross country comparisons. PISA 2003 is employed. Track choices are assumed to depend on student's ability and social origins; since...

In this paper we propose a non-equilibrium model in order to explain the search behavior of unemployed workers. This modeling strategy, framed in a rational choice paradigm, allows us to investigate the effects of negative duration dependence in the out-of-unemployment hazard rate, accounting...

Negative duration dependence in the exit rate from social assistance is an important issue addressed in the dynamic welfare participation literature. If heterogeneity is properly modelled, the decline of the exit rate is ascribed to a progressive reduction of the capability to get off welfare...

We investigate the effects of income support on unemployment and welfare dynamics when stigma is attached to welfare provision. Stigma has been modelled in the literature as a cost of entry into welfare. Allowing for psychological factors, we assume that with stigma welfare provision leads to...

The existence of collateral requirements to guarantee repayment on issued securities reduces in general the efficiency of competitive equilibria. The general equilibrium analysis is presented in a world where reputation plays no role, and the lender always expects a future payment equal to the...

A small number of countries have issued real indexed sovereign debt in recent year. This type of contracts could improve risk sharing between debtor countries and international creditors and diminish the probability of occurrence of debt crises. However, it is not clear the magnitude of these...
