We analyze four methods to measure unexplained gaps in mean outcomes: three decompositions based on the seminal work of Oaxaca (1973) and Blinder (1973) and an approach involving a seemingly naïve regression that includes a group indicator variable. Our analysis yields two principal findings....

We analyze the role of formal religious education in the intergenerational transmission of religious values. We first develop a model of school choice in which the demand for religious schooling is driven partly by the desire of parents to limit their children's exposure to the influences of...

Vast organ shortages motivated recent efforts to increase the supply of transplantable organs, but we know little about the demand side of the market. We test the implications of a model of organ demand using the universe of U.S. transplant data from 1987 to 2013. Exploiting variation in supply...

Several previous studies have relied on religious affiliation and the proximity to Catholic schools as exogenous sources of variation for identifying the effect of Catholic schooling on a wide variety of outcomes. Using three separate approaches, we examine the validity of these instrumental...

As the incidence of fatal drug overdose has quadrupled in the U.S. in the past two decades, patients awaiting organ transplants may be unintended beneficiaries. We use Vital Statistics mortality data, merged with data on the universe of transplant candidates and recipients in the U.S. from the...

We develop estimation methods that use the amount of selection on the observables in a model as a guide to the amount of selection on the unobservables. We show that if the observed variables are a random subset of a large number of factors that influence the endogenous variable and the outcome...
