By allowing agents to switch from entrepreneurship to wage work and vice versa over the life cycle, this study proposes a dynamic Jacks-of-All-Trades (JAT) model where entrepreneurs invest in highly varied skills to manage their business. We simultaneously endogenize human capital investment and...

We present findings from an evaluation study of the Dual-Teacher program, a computer- assisted instruction program, that makes lecture videos and other teaching resources from an elite urban middle school available through the internet to schools in poor and remote areas in China. The unique...

We conducted a large-scale lost letter experiment with a novel design across all seasons in Beijing to study whether ambient air pollution influences helping behavior. We assessed air pollution by PM2.5 and PM10. Our novel design allowed us to collect real-time granular data from the streets. To...

We conducted large-scale lost letter experiments in Beijing, a megacity with more than 21 million residents, to test if the observed altruistic attribute of the letter recipient would induce more passersby to return the lost letters. The treatment letters were addressed to a nationally renowned...

Using data from a rural household survey for the People's Republic of China in 2009, we examine the impact of parental migration on children's educational outcomes. Consistent with the findings of a large empirical literature, we find that parental migration has a significantly negative impact...

This paper examines the effects of county-level urbanization and natural amenities on subjective well-being (SWB) in the U.S. SWB is measured using individual-level data from the Behavioral Risk Factor Surveillance System (BRFSS) which asks respondents to rate their overall life satisfaction....

The Slovenian transition represents a slow but steady liberalization of constraints on competition. Using a unique longitudinal data set on all manufacturing firms in Slovenia over the period 1994-2001, this study analyzes how firm efficiency changed in response to changing competitive...

Data from nine transition economies in Central and Eastern Europe are used to examine the role of computer adoption for returns to education. As in western economies, computers are adopted most heavily by young, educated, English-speaking workers with the best access to local telecommunications...

Using a unique sample of new Ph.D. economists in 1987 and 1997, we examine how job seekers and their employers alter their search strategies in strong versus weak markets. The 1987 academic market was strong while the 1997 market was much weaker. A multimarket theory of optimal search suggests...

The transition to market in Slovenia created labor displacements that were on par or greater than that experienced in North America in the 1980s. A simple theoretical model suggests that factors which raise the probability of layoff should also increase the probability of a quit, predictions...
