This paper investigates the role that the entry and exit of heterogeneous firms plays in shaping aggregate fluctuations in economic activity. In so doing, it develops a dynamic stochastic general equilibrium model in which procyclical entry and countercyclical exit along a real business cycle...

This paper associates political instability to real shocks affecting the income of the median voter, in a two-period model where two political parties set redistribution in order to defend the interests of well-de¯ned constituencies. Implemented policies affect future voting outcomes and an...

This paper develops a model of endogenous growth with overlapping generations to investigate the joint determination of social security, public investment and growth in a small open economy. We argue that a pure pay-as-you-go system provides the taxpayers with the incentives to support...

In this paper, we show that the positive estimated coefficient of average social security expenditure, often detected in cross-country growt regression, can not be imputed to reverse causation, that is on economic growth pulling social security expenditure, nor to omitted variables or other...

In this paper we develop an endogenous growth model of open economies, where countries differ with respect to the quality of property rights. Within this context, we analyze two types of reforms. First, we look at growth and welfare effects of removing capital controls, given the degree of...

We model an OLG economy where productivity growth comes from two alternative sources: process innovation and learning-by-doing. There is a trade-off between the two in so far as frequent technological updates reduce the scope for learning on existing technologies. A conflict is shown to arise...

We analyze a tree-period OLG model, where a consumption good is produced by means of skilled labor and an intermediate good. Human capital accumulation depends on the aggregate stock of human capital and on the fraction of time that children spend at school, which is decided by their parents....

This paper proposes an explanation for why universal suffrage has not implied larger rich-to-poor transfers of wealth. The main argument is that, in the presence of borrowing constraints, if current taxation finances (at least partially) policies that redistribute future income, the poor, who...

Equally, poor countries display similar compulsory schooling laws but different levels of child labor and school attendance. This paper provides an explanation for the existence of child labor, which relies on the imperfect enforcement of compulsory schooling laws and is consistent with the...
