We designed a natural-field experiment in the context of local public transportation to test whether rewards in the form of lottery prizes coupled with traditional sanctions efficiently reduce free-riding. We organized a lottery in a medium-size Italian city the participation in which is linked...

We study how distributional preferences are affected by a major property rights reform that transformed informal use-rights over land traditionally characterizing rural Beninese villages in a system akin to private ownership. The design combines the randomized control-trial implementation of the...

In this paper we present an occupational choice model for entrepreneurs, in which, based on their individual skills and on the quality of their business, entrepreneurs can keep their original business, open a new business in the same or another sector along the current business (portfolio...

This paper studies the effect of decentralization on corruption in a hierarchical organization, where decentralization is intended as the delegation of control power to lower levels in a hierarchy. Decentral- ization causes a loss in control to the higher levels, thus curbing their incentives to...

Starting from the separation between formal and real authority, the paper considers a hierarchical relation where delegation of control can be used as an incentive mechanism. It shows that delegation is optimal when parties' interests are neither too divergent nor too close. In that case...

We study the impact of piracy on the quality choices of a monopolist. In the absence of piracy, the monopolist has no incentive to differentiate its products. With piracy the monopolist might instead produce more than one quality, so that differentiation arises as the optimal strategy. This is...

An integrated monopoly, where all complements forming a composite good are offered by a single firm, is typically welfare superior to a complementary monopoly. This is the "tragedy of the anticommons". We consider the possibility of competition in the market for each complement. We present a...
