In this paper, we use stochastic dynamic programming to model the choice of a municipality which has to design an optimal waste management program under uncertainty about the price of recyclables in the secondary market. The municipality can, by undertaking an irreversible investment, adopt a...

Recent European Legislation on immigration has revealed a particular paradox on migration policies. On the one hand, the trend of recent legislation points to the increasing closure of frontiers (OECD 1999, 2001,2004), also by using immigration quotas. On the other hand, there is an increase of...

During the last decade unicameral proposals have been put forward in fourteen US states. In this paper we propose a theoretical framework casting some lights on the drawbacks of bicameral state legislatures and on the effects of the proposed constitutional reforms. In a setting where lawmakers...

The present paper investigates the functioning of an Emission Trading System (ETS) and its impact on the diffusion of environmental-friendly technological innovation in the presence of firms' strategic behaviours and sanctions to non-compliant firms. For this purpose, we study an evolutionary...

This paper shows the importance of technological synergies among heterogeneous firms for aggregate fluctuations. First, we document six novel empirical facts using microdata that suggest the existence of important technological synergies between trading firms, the presence of positive...

This paper describes Gary Becker's theoretical models of marriage. At the micro-level, these are all rational choice models. At the market level, Becker offers two major types of models: partial equilibrium models based on Price Theory as taught by Marshall and Friedman and optimal sorting...

This paper develops a dynamic general equilibrium model with three distinct social groups, capitalists, private workers and public employees. After solving for the status quo equilibrium, which can mimic the advantages of employment in the public sector in most EU countries, the paper looks for...

We show that privatization can be beneficial even if the government is rational and benevolent, and if the firm's economic and informational environment is independent of the governance structure. The model assumes that wage contracts between the firm's owner (government or private entrepreneur)...
