We examine the role of increased life expectancy in raising human capital investment during the process of economic growth. We develop a continuous time, overlapping generations model in which individuals make optimal schooling investment choices in the face of a constant probability of death....

We examine the dynamic responses of income and poverty to increased investment in the human capital of new cohorts of workers, using a quantitative macroeconomic model with realistic demography. Compared to a baseline in which the rate of human capital investment currently observed in every...

This chapter explores the ways in which changing the age structure of the population in the macroeconomic models affects variables, such as consumption, wages, government spending, and saving. The chapter also presents the basic data on the ways in which the age structure of the population is...

This chapter examines the relationship between health and economic growth. Across countries, income per capita is highly correlated with health, as measured by life expectancy or a number of other indicators. Within countries, there is also a correlation between people’s health and income....

This paper examines changes over time in the importance of the lending channel in the transmission of monetary shocks to the real economy. We first use a simple extension of the Bernanke-Blinder model to isolate the observable factors that affect the strength of the lending channel. We then show...

We develop a novel method for assessing the effect of constraints imposed by spatially-fixed natural resources on aggregate economic output. We apply it to estimate and compare the projected effects of climate change and population growth over the course of the 21st century, by country and...
