In this paper we have developed a model which analyzes price competition in the deregulated Spanish electricity market. This model is the first to take explicitly into account the mechanism designed in the recent Spanish Electricity Law for settling stranded costs payments.

This paper presents a political economy model in which the voters want to control moral hazard on the part of the incumbent and select a competent candidate to be in office. We focus on elections which take place repeatedly as the basic disciplinary and screening mechanism. It is shown that...

In this paper we present a class of binary choice models for panel data with the following features : (i) The explanatory variables are predetermined but not strictly exogenous. (ii) Individual effects are allowed to be correlated with the explanatory variables.

It is well known from time series analysis that shocks to aggregate output have very persistent effects. This paper argues that the relation between the expected growth rate of a firm and its size\ provides a microfoundation for such aggregate persistence. The empirical evidence indicates that...

We explore the business-cycle implications of agency problems between firms and financiers. We show how these problems create liquidity shortages that can lead to corporate bankruptcy, and may generate aggregate, endogenous cycles in an economy that otherwise would have had a unique, stationary...

We study the properties of mimicking portfolios in an intertemporal APT model, in which the conditional mean and covariance matrix of returns vary in an interdependent manner. We use a signal extraction approach, and relate the efficiency of (possibly) dynamic basis portfolios to mean square...

This paper presents the most recent literature about Equilibrium Search Models with wage posting. Starting with the basic Burdett and Mortensen (1998) model, I describe the main consequences of departing from its two main assumptions: random matching and a linear production function. I show how...
