Concern about “open space” is growing. Conservation advocates worry that private land use decisionmakers preserve too little open space. Yet private land developers are deciding on their own to preserve open space in new developments because it provides amenities to purchasers of lots....

Using a model of probabilistic voting, we analyse the impact of aid on the political equilibrium in the recipient country or region. We consider two kinds of politicians: the benevolent one is interested in promoting social welfare whereas the other one is clientelistic, his only goal being to...

International differences in fuel taxation are huge, and may be justified by different local negative externalities that taxes must correct, as well as by different preferences for public spending.

Multiple group memberships are the rule rather than the exception. Within a linear public good game, we experimentally investigate two possible factors that impact the decision to cooperate in a smaller, local or a larger, global group: diverging marginal per capita returns, resulting in...

This paper examines allocation of local public goods over jurisdictions (villages) with individuals with identical tastes and different incomes, in a model with democratic institutions and majority rule. The median voter (in income) in each jurisdiction determines the probability of re-election...

This paper examines how citizens decide on their reservation utilities (expectations), in a model with democratic institutions and majority rule. If all individuals have identical incomes, then political competition amongst citizens, to attract resources from the government brings reservation...

We study a model where agents, located in a social network, decide whether to exert effort or not in experimenting with a new technology (or acquiring a new skill, innovating, etc.). We assume that agents have strong incentives to free ride on their neighbors' effort decisions. In the static...
