The paper studies the determinants of income distribution and growth in an overlapping generations economy with heterogenous households. Our framework has the following main features: (1) heterogeneity of consumers with respect to wealth and parental human capital; (2) intergenerational...

This paper analyses an open economy Ramsey model with an endogenous labour supply without capital. The technology defines an optimal firm size. Changes to the number of firms is subject to adjustment costs, so that the entry dynamics is determined endogenously. We find that there is a short run...

The macroeconomic effects on growth, investment and private sector employment of different ways of rolling back the welfare state are analysed. Cutting public spending on private goods induces a lower interest rate, a higher wage, a lower capital stock and a fall in employment. Cutting public...

We show that a minimum wage introduced in the presence of asymmetric information about worker productivities will lead to lower unemployment levels than predicted by the standard labour market model with heterogeneous labour and symmetric information. -- minimum wages ; unemployment ; asymmetric...

In this model of education, where individuals are exposed both to educational risk and to wage risk within the skilled sector, successful graduation depends both on individual effort to study and on public resources. We show that insuring the present risks is a dichotomic task: Wage risk is...

In a model with ex-ante homogenous households, earnings risk and a general earnings function, we derive the optimal linear labor tax rate and optimal linear education subsidies. The optimal income tax trades off social insurance against incentives to work and to invest in human capital....

Employment protection systems are known to generate significant distortions in firms' hiring and firing decisions. We know much less about the impact of these regulations on worker effort. The goal of this paper is to fill in this gap and in particular to assess whether the provision of...

This paper reviews the U.S. welfare reform efforts over the 1990s and the effects of these reforms to date. Seven lessons of potential interest to European observers are discussed, with particular attention to the conclusions of more recent research. Such research indicates, for example, that...

This paper reviews the Italian unemployment experience, analyzing in particular the time-series behavior of unemployment rates along the path that brought Italy into Europe s Economic and Monetary Union, and their disaggregated structure across geographical and demographic dimensions. High...

In OECD countries watching television is by far the most time-consuming form of leisure. Surprisingly, television viewing is positively correlated with work hours across countries. A simple model based on the notion of aggregate strategic complementarities in social leisure is developed which...
