This paper develops a model of social interactions with endogenous association. People are assumed to invest in relationships to maximize their utility. Even in a linear-in-means model, when associations are endogenous, the effect of macro-group composition on behavior is non-linear and varies...

Psychologists have found that the age at which successful practitioners typically do their best work varies across professions, but they have not considered whether these peak ages change over time, as economic models suggest they might. Using auction records, we estimate the relationship...

This paper investigates the local impact of biomedical research on mortality in the USA. Causally estimating the marginal value of biomedical research is challenging due to a lack of micro data linking health outcomes to plausibly exogenous variation in research. We create a new linkage between...

The rapid diffusion and use of new ideas are critical for advancing and realizing the value of innovation. This paper explores the impact of demographic characteristics of innovators and potential adopters on the adoption of important new scientific ideas through networks. Using rich,...

This paper examines the transmission of human capital from parents to children using variation in parental influence due to parental death, divorce, and the increasing specialization of parental roles in larger families. All three sources of variation yield strikingly similar patterns which show...

We study the effects of peer gender composition, a proxy for female-friendliness of environment, in STEM doctoral programs on persistence and degree completion. Leveraging unique new data and quasi-random variation in gender composition across cohorts within programs, we show that women entering...

Institutional leaders have long championed interdisciplinary research; however, researchers have paid relatively little attention to the people responding to such calls and their subsequent career outcomes. With the benefit of two large datasets spanning from 1986 through 2016, we show that...

Policymakers, faced with different options for replacing lost earnings, have had limited evidence to inform their decisions. The current economic crisis has highlighted the need for data that are local and timely so that different fiscal policy options on local economies can be more immediately...

The relationship between population health and measures of economic well-being and economic activity is a long standing topic in health economics (Preston, 1975; Cutler, Deaton, and Lleras-Muney, 2006; Ruhm, 2000). The conceptual issues in analyzing the complicated link between health and economic...

We make several contributions to understanding the socio-demographic ramifications of the COVID-19 epidemic and policy responses on employment outcomes of subgroups in the U.S., benchmarked against two previous recessions. First, monthly Current Population Survey (CPS) data show greater declines...
