The evidence strongly suggests a robust negative relationship between income and fertility, and a positive relationship between income and longevity. This is puzzling for standard dynamic models. For instance, altruistic models that use the most standard preferences in macro --time separable...

The International Handbook on Teaching and Learning Economics provides a comprehensive resource for instructors and researchers in economics, both new and experienced. This wide-ranging collection is designed to enhance student learning by helping economic educators learn more about course...

This paper provides a theory that explains the cross-country distribution of average years of schooling, as well as the so called human capital premium puzzle. In our theory, credit frictions as well as differences in access to public education, fertility and mortality turn out to be the key...

 Extensive evidence from cross-sectional data reveals a robust negative relationship betweenfamily income and fertility. This paper argues that constraints to intergenerational transfersare crucial for understanding this relationship. If parents could legally impose debt obligationson their...

Life expectancy around the world has increased substantially since 1970. In contrast, consumption per capita has fallen in some countries, remained stagnant, or sharply increased in others. What are the welfare gains of the systematic increase in life expectancy around the world? How does a...

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 holds under more standard assumptions....

The purpose of this paper is to analyze the role of collateral constraints as a transmission mechanism of monetary shocks. 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 injected via...

This paper studies fertility decisions in an Aiyagari-Huggett economy extended to include endogenous fertility. The challenge is to explain both why fertility decreases with income, and why there is intergenerational persistence of inequality. The model features non-isoelastic altruism,...

Most education around the globe is public. Moreover, invest rates in education as well as schooling attainment differ substantially across countries. We contruct a general equilibrium life-cycle model that is consistent with these facts. We provide simple analytical solutions for the optimal...
