Recent work highlights a falling entry rate of new firms and a rising market share of large firms in the United States. To understand how these changing firm demographics have affected growth, we decompose productivity growth into the firms doing the innovating. We trace how much each firm...

Statistical agencies typically impute inflation for disappearing products based on surviving products, which may result in overstated inflation and understated growth. Using U.S. Census data, we apply two ways of assessing the magnitude of "missing growth" for private nonfarm businesses from...

The "Easterlin paradox" suggests that there is no link between a society's economic development and its average level of happiness. We re-assess this paradox analyzing multiple rich datasets spanning many decades. Using recent data on a broader array of countries, we establish a clear positive...

Externalities play a central role in most theories of economic growth. We argue that international externalities, in particular, are essential for explaining a number of empirical regularities about growth and development. Foremost among these is that many countries appear to share a common long...

We explore the relationships between subjective well-being and income, as seen across individuals within a given country, between countries in a given year, and as a country grows through time. We show that richer individuals in a given country are more satisfied with their lives than are poorer...

This paper provides estimates of the economic impact of non-communicable diseases (NCDs) in China and India for the period 2012-2030. Our estimates are derived using WHO's EPIC model of economic growth, which focuses on the negative effects of NCDs on labor supply and capital accumulation. We...

Over the last 50 years, there has been a remarkable convergence in the occupational distribution between white men, women, and blacks. We measure the macroeconomic consequences of this convergence through the prism of a Roy model of occupational choice in which women and blacks face frictions in...

Economic growth is typically measured in per capita terms. But social welfare should arguably include the number of people as well as their standard of living. We decompose social welfare growth -- measured in consumption-equivalent (CE) units -- into contributions from rising population and...
