Unit roots in output, an exponential 2% rate of convergence and no change in the underlying dynamics of output seem to be three stylized facts that can not go together. This paper extends the Solow-Swan growth model allowing for cross-sectional heterogeneity. In this framework, aggregate shocks...

We claim that the stock market encourages business creation, innovation, and growth by allowing the recycling of "informed capital". Due to incentive and information problems, new start-ups face high flotation costs. Sustaining a tight relationship with a monitor allows them to postpone their...

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...

Spain has had a serious structural unemployment problem for the last 20 years. This paper argues that the interaction of /ring costs and job-to-job 0ows added to changes in unemployment bene/ts, could provide an explanation for equilibrium unemployment increasing, since 1984. First, we construct...

Unit roots in output, an exponential 2 per cent rate of convergence and no change in the underlying dynamics of output seem to be three stylized facts that cannot go together. This paper extends the Solow-Swan growth model allowing for cross-sectional heterogeneity. In this framework, aggregate...

This paper develops a structural empirical model of contraception and participation choice under imperfect control of fertility, learning and unobserved heterogeneity to identify, estimate and give a behavioral content to the effect of the first born child on female labor supply. Family planning...

We derive computationally simple and intuitive score tests of neglected serial correlation in unobserved component univariate models using frequency domain techniques. In some common situations in which the information matrix is singular under the null we derive extremum tests that are...

Much of the growing literature on tactical and strategic asset allocation uses vector autoregressive models (VAR) for returns and predictors. Since the portfolio advice they generate may be misleading if those models are not an accurate description of reality, we evaluate the implied joint...

This paper analyzes the effects on ex ante risk-shifting incentives and ex post fiscal costs of three policies that are frequently used in dealing with banking crises, namely, forbearance from prudential regulations, extension of blanket deposit guarantees, and provision of unrestricted...

Firms that are more highly levered are forced to raise capital more often, a process that leads to the generation of information. Of course transparency can improve the allocation of capital. However, when the information about the firm affects the terms under which the firm transacts with its...
