Using a class of endogenous growth models that exhibit international spillovers, we show that most of the cross-country differences in output per worker are explained by barriers to the accumulation of rival factors (physical and human capital) rather than by barriers to the accumulation of...

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...

We study the shape of the aggregate production function in the presence of land-intensive agriculture. The traditional Cobb-Douglas formulation is corrected to include a "diversification component." The implied TFP differences across countries are larger than what Solow residuals suggest.

This paper seeks to device and estimate an accounting framework for international comparison of income that takes into account relevant features of poor countries that are often disregarded in the more traditional single-good, Cobb-Douglas accounting framework. Our framework allows for multiple...

This paper reviews 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 money...
