We study political distortions that emerge in situations where agents' political power is disproportionate with respect to their economic power. We provide a precise definition which adopts the same measure unit, the Shapley value, to evaluate both the economic and the political power. We show...

This paper describes policy alternatives as lotteries, and studies how policy preferences are distorted by the cognitive anomalies postulated by Prospect Theory. Loss aversion induces a status quo bias. However, due to the reflection effect, the bias is asymmetric: too moderate attitudes toward...

In this paper I explore asymmetric coalitional bargaining. Players are possibly different in preferences and in probability to place threats; the agreements emerge randomly during negotiations. As a result, players negotiate with different degree of enthusiasm. I compute a solution that I call...

In this paper we describe systemic financial risk as a pollution issue. Free riding leads to excess risk production. This problem may be solved, at least partially, either with financial regulation or taxation. From a normative viewpoint taxation is superior in many respects. However, reality...

Sanctions induce political instability. We present a model where sanctioned regimes may decide to repudiate their public debts in order to keep internal support. To be effective, this strategy requires the share of foreign debt to be larger than the minimum quota of population which is needed...

We experimentally study the effects of common fate on voluntary contributions to linear public goods. In each period, earnings are assigned to subjects according to the outcome of a lottery. We manipulate the level of common fate across treatments by varying the degree of harmony in the lottery...

The main findings of the theory on the private provision of public goods under the assumptions of identical individuals and normality of both the public good and private consumption are that: 1) there exists a unique Nash equilibrium pattern of contributions in which everybody contributes the...

Does the hypothesis of 'love for (group) efficiency' account for subjects' over-contribution in public good games? By using data from a VCM experiment with heterogeneous endowments and asymmetric information, we estimate a quantal response equilibrium (QRE) extension of a model in which subjects...
