International climate protection investments (Joint Implementation and Clean Development Mechanism projects) are burdened with problems of contract enforcement, which prevent the realisation of efficiency gains associated with these investments. The paper analyses this problem from the...

This paper explores the relationship between environmental protection and international capital movements, when tax policy is endogenous (through voting). A two-period general equilibrium model of a small open economy is specified to compare the effects of two different constitutions (commitment...

Data on the growth performances of countries with similar comparative (dis)advantage and political institutions reveal a striking variation across world regions. While some former autocracies such as the East Asian growth miracles have done remarkably well, others such as the Latin American...

This paper revisits the empirical evidence about the link between firms’ performance and their international status, based on a large sample of Italian enterprises. To this purpose, we merged two waves of the Capitalia survey (1998-2000, and 2001-2003) retrieving firm level data for roughly...

This paper investigates the private provision of public goods in segregated societies. While most research agrees that segregation undermines public provision, the findings are mixed for private provision: social interactions, being strong within groups and limited across groups, may either...

We present experiments on repeated non-cooperative network formation games, based on Bala and Goyal (2000). We treat the one-way and the two-ways flow models, each for high and low link costs. The models show both multiple equilibria and coordination problems. We conduct experiments under...

In a society composed of a ruler and its citizens: what are the determinants of the political equilibrium between these two? This paper approaches this problem as a game played between a ruler who has to decide the distribution of the aggregate income and a group of agents/citizens who have the...

Many types of economic and social activities involve significant behavioral complementarities (peer effects) with neighbors in the social network. The same activities often exert externalities that cumulate in "stocks" affecting agents' welfare and incentives. For instance, smoking is subject to...
