We introduce labor contracts in a framework of optimal redistribution: firms have some local market power and try to discriminate among heterogeneous workers. In this setting we show that if the firms have perfect information, i.e., they perfectly discriminate against workers and take all the...

In this paper we present a model of credit market with several homogeneous lenders competing to finance an investment project. Contracts are non-exclusive, hence the borrower can accept whatever subset of the offered loans. We use the model to discuss efficiency issues in competitive economies...

In this note we consider a basic property of common agency models: pure strategy equilibria of games where principals compete in direct mechanisms are robust to the possibility that principals might deviate and use more complex indirect mechanisms to design their contracts. We show that this...

Consider an overlapping generation growth model involving identical countries whose fiscal policy reduces to a pay-as-you-go system with flat rate benefits and uniform payroll tax rate. In autarky, the tax rate is chosen so as to achieve a compromise between intragenerational and...

This paper provides a model of nonlinear income taxation in a context of international mobility. We consider two identical countries, in which each government chooses non-cooperatively redistributive taxes. It is shown that when skilled workers can move at low cost, the income taxation does not...

This paper shows that consumers may benefit when a regulator chooses not to regulate a final product in an industry characterized by an unregulated essential facility sold through non-linear tariffs. Two main reasons drive this result. First, the regulator maximizes social welfare and values the...
