We show that endogenous firm selection provides a new welfare margin for heterogeneous firm models of trade (relative to homogeneous firm models). Under some parameter restrictions, the trade elasticity is constant and is a sufficient statistic for welfare, along with the domestic...

We explore the phenomenon of coauthorship by economists who share a surname. Prior research has included at most three economist coauthors who share a surname. Ours is the first paper to have four economist coauthors who share a surname, as well as the first where such coauthors are unrelated...

Do men and women have different social preferences? Previous findings are contradictory. We provide a potential explanation using evidence from a field experiment. In a door-to-door solicitation, men and women are equally generous, but women become less generous when it becomes easy to avoid...

We present a model of investment hangover motivated by the Great Recession. In our model, overbuilding of residential capital requires a reallocation of productive resources to nonresidential sectors, which is facilitated by a reduction in the real interest rate. If the fall in the interest...

We use a newly assembled sample of 1,528 regions from 83 countries to compare the speed of per capita income convergence within and across countries.  Regional growth is shaped by similar factors as national growth, such as geography and human capital.  Regional convergence rate is about 2%...

China committed itself to reduce the carbon intensity of its economy (the amount of CO2 emitted per unit of GDP) by 40?45% during 2005?2020. Yet, between 2002 and 2009, China experienced a 3% increase in carbon intensity, though trends differed greatly among its 30 provinces. Decomposition...

To what extent do barriers to knowledge transmission influence a firm?s decision to expand? Using a worldwide dataset on foreign subsidiaries, I show that multinational corporations are, on average, about 12% less likely to horizontally expand a sector that is one standard deviation above the...

In rural areas in Spain, the incorporation of women in the job market has been a long road laden with obstacles, while the accumulation of symbolic capital by men has produced lack of visibility and legitimacy of women?s work. Despite this constraint, women have become active economic agents....

Why do people vote? We argue that social image plays a signi?cant role in explaining turnout: people vote because others will ask. The expectation of being asked motivates turnout if individuals derive pride from telling others that they voted, or feel shame from admitting that they did not...

Primary PM2.5 emissions contributed significantly to poor air quality in China. We present an interdisciplinary study to measure the magnitudes of socioeconomic factors in driving primary PM2.5 emission changes in China between 1997?2010, by using a regional emission inventory as input into an...
