Economists have studied the impact of numerous state laws, from welfare rules to voting ID requirements. Yet for all this policy evaluation, what do we know about policy diffusion—how these policies spread from state to state? We present a series of facts based on a data set of over 700 U.S....

Assessing the state of American entrepreneurship requires not simply counting the quantity but also the initial quality of new ventures. Combining comprehensive business registries and predictive analytics, we present estimates of entrepreneurial quantity and quality from 1988-2014. Rather than...

Self-control problems constitute a potential explanation for the under-investment in preventive health care observed in low-income countries. A commonly proposed policy tool to solve such problems is offering consumers commitment devices. We conduct a field experiment to evaluate the...

We explore whether the composition of the physician work force is impacted by the clinical standards imposed on physicians under medical liability rules. We theorize that physicians of particular backgrounds will be attracted to regions when the malpractice laws of those regions favor the type...

Developing countries spend vast sums on subsidies. Beneficiaries are typically selected via either a proxy-means test (PMT) or through a decentralized identification process led by local leaders. A decentralized allocation may offer informational or accountability advantages, but may be prone to...

I use a quantitative economic geography model to explore subsidy competition among U.S. states. I ask what motivates state governments to subsidize firm relocations and quantify how strong their incentives are. I also characterize fully non-cooperative and cooperative subsidy choices and assess...

We estimate the minimum wage's effects on low-skilled workers' employment and income trajectories. Our approach exploits two dimensions of the data we analyze. First, we compare workers in states that were bound by recent increases in the federal minimum wage to workers in states that were not....

We study associations among women's current marital status, past marital history, and later-life labor force participation. We first document these relationships using data from the 1986 to 2008 waves of the Survey of Income and Program Participation (SIPP). We then exploit variation in laws...

This paper evaluates the effects of the implementation of a structured early stimulation curriculum combined with a nutritional intervention through public large-scale parenting support services for vulnerable families in rural Colombia, known as FAMI, using a clustered randomized controlled...

I study the impact of transportation on health in the rural US, 1820–1847. Measuring health by average stature, I find that greater transportation linkage, as measured by market access, in a cohort's county-year of birth had an adverse impact on its health. A one-standard deviation increase in...
