This paper explores the quantitative implications of a class of endogenous growth models for cross-country income differences. These models exhibit international spillovers, no scale effects and conditional convergence, and thus they overcome some difficulties faced by the early generation of...

This paper studies the role of collateral constraints in transforming small monetary shocks into large persistent output fluctuations. We do this by introducing money in the heterogeneous-agent real economy of Kiyotaki and Moore (1997). Money enters in a cash-in-advance constraint and is...

Lucas (2004) asserts that 'Of the tendencies that are harmful to sound economics, the most seductive, and in my opinion, the most poisonous, is to focus on questions of distribution...The potential for improving the lives of poor people by finding different ways of distributing current...

This note extends Lucas' (1987) analysis to assess welfare gains of economic growth and welfare costs of consumption inequality, both within and across countries. We find that the welfare costs of inequality are significantly larger than the gains of economic growth. While the gains of economic...

The city size distribution of many countries is remarkably well approximated by a Pareto distribution. We study what constraints this regularity imposes on standard urban models. We find that under general conditions urban models must have (i) a balanced growth path and (ii) a Pareto...

Theoretical studies have shown that under unorthodox assumptions on preferences and production technologies, collateral constraints can act as a powerful amplification and propagation mechanism of exogenous shocks. We investigate whether or not this result hold under more standard assumptions....
