We link information on graduates from many cohorts to their high-school and college records and demographics to infer the impact of college major on earnings. We develop an estimator to handle potential non-response bias and identify non-response using an affinity measure--the potential...

We link ATUS 2003-04 to March CPS data and examine market work's effects on non-market activity. In a structural model fixed time costs of work generate a utility-equivalent of 8% of income to be overcome before working becomes optimizing.

We illustrate problems of measuring discrimination using elections to AEA offices. With a new econometric technique, we find female candidates have a much better than random chance of victory. This advantage is either reverse discrimination or reflects beliefs that women are more productive. The...

In a multivariate varying-coefficient model, the response vectors <bold>Y</bold> are regressed on known functions <bold>v</bold>(<bold>X</bold>) of some explanatory variables <bold>X</bold> and the coefficients in an unknown regression matrix <bold> <italic>θ</italic> </bold>(<bold>Z</bold>) depend on another set of explanatory variables <bold>Z</bold>. We provide statistical tests, called local and...

We consider a new inverse probability weighted estimator for the local average treatment effect parameter where the instrument propensity score is estimated by local polynomial regression. We derive its asymptotics and provide a higher order expansion of its asymptotic MSE.
