This paper considers market economies involving the choice of a public environment when there are nonconvexities in production. It discusses the decentralization of efficient allocations by means of valuation equilibrium, adapting to many private goods the notion due to Mas-Colell (1980) which...

This paper studies the principal-multiagent model of a firm subject to adverse selection. We focus on agents who have complete information. We propose some desirable properties to be satisfied by mechanisms implementing the first-best in Nash equilibrium: (i) enforceability (a property related...

In a context of economic integration, we analyse the strategic effect of wo policies: merger policy and state aid policy. When governments play a Stackelberg policy game before firms compete in the market we find that: a) only under certain conditions, the leader country chooses a merger policy...

Simulation estimators, such as indirect inference or simulated maximum likelihood, are successfully employed for estimating stochastic differential equations. They adjust for the bias (inconsistency) caused by discretization of the underlying stochastic process, which is in continuous time. The...

We develop a dynamic political model of dividing a fixed amount of money among n districts. There are two political parties that make proposals on such divisions and compete in each district. Each district elects a representative to a legislature. Each party is governed by its representatives...

In the brain drain literature models with heterogeneous agents typically predict that all agents who get tertiary education will try to migrate. Hence, the skill composition of the migration flow is the same as that of the skilled population left behind. This result, however, may not represent...

Our analysis yields some conclusions about the political role of regions in the formation of supranational economic areas, which turns out to be quite different from the role of nations. The claim that regions have more incentives than nations to attain a fiscal agreement implying full economic...

In the context of the recent electricity market reforms in Europe and the US, we evaluate the performance of the Spanish pool. Our method is not based on price-cost estimates but rather on the different behavior of operators with higher market power as compared to the behavior of more...

In this paper I present an explanation to the fact that in the data wealth is substantially more concentrated than income. Starting from the observation that the composition of households' portfolios changes towards a larger share of high-yield assets as the level of net worth increases, I first...

We analyze a one-dimensional model of spatial political competition with two parties and uncertainty on the distribution of voters types. We assume that parties are formed by regular members and professional politicians; members care about the policy enacted, while professional politicians, on...
