This paper studies the aggregate welfare consequences of changes in the prescribed penalty for personal bankruptcy and in social insurance policies when borrowing limits may respond to these changes. It uses a dynamic general equilibrium model of an exchange economy with incomplete markets and a...

Abstract This paper extends a model of endogenous growth through the introduction of a component of knowledge that makes new technologies more productive than older vintages. Creative destruction or obsolescence of technologies underlies the growth process. In this setup, the growth effects of...

Credit cards offer a limit, rather than a specific loan size, at a pre-approved interest rate. This paper studies the determination of these credit limits jointly with default in the presence of one-period debt. I adapt the standard incomplete markets macroeconomic model of one-period unsecured...

This paper studies economies with complete markets where there is positive default on consumer debt. In a simple tractable two-period model, households can default partially, at a finite punishment cost, and competitive intermediaries price loans of different sizes separately. This environment...

This paper investigates the factors that have shaped the demographic transition in a number of European countries (Sweden, England, and France) since the mid 18th century. The analytical framework is a version of the neoclassical growth model with dynastic preferences calibrated to match the...

This paper investigates the determination of social security within a general equilibrium, overlapping-generations model where agents live for many periods, and replacement rates are determined through voting in each period by forward looking agents. The distinctive feature is the study of...

This paper integrates the analysis of choices on education and on technology adoption to study international economic disparities. Two candidate explanations are considered: differences in distortions that affect the cost of technology adoption and differences in the effectivenss of schools. The...

This paper extends a model of endogenous growth through the introduction of a component of knowledge that makes new technologies more productive than older vintages. Creative destruction or obsolescence of technologies underlies the growth process. In this setup, the growth effects of various...
