The assessment of income inequality can be investigated looking at the solution concepts of the cooperative game theory. We propose a multi-factorial decomposition of the Atkinson index by income sources and evaluate it as a cooperative game of the social cost of inequality. This framework...

Can a bank increase its profi…t by subsidizing inactivity? This paper suggests this may occur, due to the presence of hidden information, in a monopolistic credit market. Rather than offering credit in a pooling contract, a monopolist bank can sort borrowers through an appropriate subsidy to...

This paper provides a simply theory to explain the impact of sanctions on a regime's policies and behavior. Sanctions are generally put to strip the target country from its available rents and weaken the government's stance against growing discontent in the population. We show however that...

This article investigates the impact of credit allocation on heterogeneous wealth entrepreneurs. We show that with decreasing risk aversion and unobservable wealth, poorer borrowers exert more effort. As a consequence of endogenous adverse selection, they are either excluded from the market or...

Equality of opportunity is a political ideal which requires that ex-ante inequalities, and only those inequalities, should be eliminated. Justice requires leveling the playing field by rendering everyone's opportunities equal in an appropriate sense, and then letting individual choices and their...

Credit market imperfections can prevent the poor from making profitable investments. Under asymmetric information observable features, such as wealth and collateral, play an important role in determining who gets credit, in violation of the Equality of Opportunity principle. We define equality...

Credit market imperfections can prevent the poor from making pro table investments. Under asymmetric information observable features, such as wealth and collateral, play an important role in determining who gets credit, in violation of the Equality of Opportunity principle. We de ne equality of...

We analyze mutual insurance arrangements (policies based on risk-sharing among a pool of policyholders) when consumers choose a self-insurance effort, that is an effort decreasing the size of any loss occurring. We consider both cooperative and non-cooperative strategies in the effort choice....

This paper investigates the role of unobservable wealth differences on credit market equilibrium, given there is also asymmetric information concerning effort preferences and choices. In equilibrium, poor but able entrepreneurs may subsidise the rich and incompetent or be excluded. As a result,...
