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...

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 article studies the effects of demographics on the mix of tax rates on labor and capital. It uses a quantitative general-equilibrium, overlapping-generations model where tax rates are voted without past commitments in every period and characterized as a Markov equilibrium. In the United...

A skill-biased change in technology can account at once for the changes observed in a number of important variables of the US labour market between 1970 and 1990. These include the increasing inequality in wages, both between and within education groups, and the increase in unemployment at all...

This article studies the effects of demographics on the mix of tax rates on labour and capital. It uses a quantitative general-equilibrium overlapping-generations model where tax rates are voted without past commitments in every period and characterized as a Markov equilibrium. In the U.S., the...

This paper presents a macroeconomic model of unsecured consumer debt and default where credit conditions consist of pre-approved interest rates and borrowing limits, a feature of actual credit cards. All loans, irrespective of their size and risk, take place against the same type of credit line,...

This paper investigates the factors that 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 Swedish...

This paper develops a theory of debt management in which government financing decisions have distributional consequences. We consider a constant aggregate endowment economy in which the government finances exogenous stochastic public spending needs with uniform lump sum taxes and...
