Due to population aging, GDP growth per capita and GDP growth per working-age adult have become quite different among many advanced economies over the last several decades. Countries whose GDP growth per capita performance has been lackluster, like Japan, have done surprisingly well in terms of...

The 20th century beheld a dramatic transformation of the family. Some Kuznets style facts regarding structural change in the family are presented. Over the course of the 20th century in the United States fertility declined, educational attainment waxed, housework fell, leisure increased, jobs...

We study the optimal allocation of R&D resources in an endogenous growth model with an innovation network, through which one sector's past innovations may benefit other sectors' future innovations. First, we provide closed-form sufficient statistics for the optimal path of R&D resource...

Women's contribution to the economy has been markedly underestimated in predominantly agricultural societies, due to their widespread involvement in unpaid agricultural work. Combining data from the US Census and several early sources, we create a consistent measure of male and female employment...

We study the persistent effects of temporary changes in U.S. federal corporate and personal income tax rates using a narrative identification approach. A corporate income tax cut leads to a sustained increase in GDP and productivity, with peak effects between five and eight years. R&D spending...

How do children affect women in science? We investigate this question using rich biographical data, linked with patents and publications, for 83,000 American scientists in 1956 at the height of the baby boom. Our analyses reveal a unique life-cycle pattern of productivity for mothers. While...

Good health is important for employment at older ages. However, little is known about how health-related functional abilities interact with occupational demands to shape work capacity. Using new data, we quantify individuals' functional abilities, combine that information with...

Using panel data from 23 OECD countries, I document that wages grow more over the life-cycle in countries where job-to-job mobility is more common. A life-cycle theory of job shopping and accumulation of skills on the job highlights that a more fluid labor market allows workers to faster...

We study the productivity-pay relationship in the United States and Canada along two dimensions. The first is divergence: the degree to which the levels of productivity and pay have diverged. The second is delinkage: the degree to which incremental increases in the rate of productivity growth...

We construct new technology indicators using textual analysis of patent documents and occupation task descriptions that span almost two centuries (1850-2010). At the industry level, improvements in technology are associated with higher labor productivity but a decline in the labor share....
