This paper studies the optimal fiscal treatment of addictive goods (cigarettes, drugs, fatty foods, alcohol, gambling etc.). It shows that, when agents have private information about their productivity levels and their degree of rationality, the Atkinson and Stiglitz result of optimal uniform...

This paper studies an optimal taxation problem in a dynamic economy inhabited by individuals who differ in productivity (as in Kocherlakota, 2006) and in the short-term discount factor. We determine incentive compatible Pareto optimal allocations in a multidimensional screening model where...

In most economies, a fair allocation does not exist. Thus, it seems that we are condemned to live in an unfair world, since we are not happy with what we have and we look at the others with envious eyes. In this paper we want to give an hope for a more equitable society.

The paper proposes a notion of fairness which overcomes the conflict arising between efficiency and the absence of envy in economies with uncertainty and asymmetrically informed agents. We do it in general economies which include, as particular cases, the main differential information economies...

We provide international evidence on the relationship between the extent of underpricing related to initial public offerings (IPOs) and the distance of the issuing firm from the financial centre of a country: for France, Germany and Italy, the higher the distance, the higher the level of...

This paper studies the notion of fairness in pure exchange economies involving uncertainty and asymmetric information. We propose a new concept of coalitional fair allocation in order to solve the tension that may exist between efficiency and envy-freeness when the equity of allocations is...

We derive a set of optimal environmental regulations in the presence of asymmetric information about pollution abatement costs, where compliance may have to be induced through appropriate monitoring and enforcement measures. The regulator commits to monitoring of compliance with incentive...

We use data from the Italian manufacturing industry to document a positive relation- ship between delegation of decisions within organizations and involvement in research and development. This positive correlation is robust to controlling for the determi- nants of R&D within firms such as the...

How does the punishment for default affect repayment behavior? We use administrative data provided by the leading Italian lender of unsecured credit to the household sector to investigate the effect of two potentially important factors: judicial efficiency and the availability of informal credit...

We show that competing firms relax overall competition by lowering future barriers to entry. We illustrate our findings in a two-period model with adverse selection where banks strategically commit to disclose borrower information. By doing this, they invite rivals to enter their market....
