Capital goods trade and economic development
Almost 80 percent of capital goods production in the world is concentrated in 10 countries. Poor countries import most of their capital goods. We argue that international trade in capital goods has quantitatively important effects on economic development through two channels: (i) capital formation and (ii) aggregate TFP. We embed a multi country, multi sector Ricardian model of trade into a neoclassical growth model. Barriers to trade result in a misallocation of factors both within and across countries. We calibrate the model to bilateral trade flows, prices, and income per worker. Our model ...

Technology Adoption, Mortality, and Population Dynamics
We develop a quantitative theory of mortality and population dynamics. We emphasize individuals' decisions to reduce their mortality by adopting better health technology. Adoption becomes cheaper as more individuals use better technology. It also confers a dynamic externality by increasing the future number of individuals who use the better technology. Our model generates a diffusion curve whose shape dictates the pace of mortality reduction. The model explains historical trends in mortality rates and life expectancies at various ages and population dynamics in Western Europe. Unlike ...
Is the U.S. Looking Like Italy? Projections on COVID-19 Death Rates
After adjusting for population, daily coronavirus deaths are less in the U.S. than in Italy. However, the U.S. seems to be catching up with Italy on that metric.

Adoption confers a dynamic externality: Adoption becomes cheaper as more individuals use better technology. Our model generates a diffusion curve, whose shape dictates the pace of mortality reduction. The model explains historical trends in mortality rates and life expectancies at various ages, and population dynamics in Western Europe. Unlike Malthusian theories based solely on income, ours is consistent with the observed ...

Discouraged workers: what do we know?
