This book reviews recent approaches for partial identification of average treatment effects with instrumental variables in the program evaluation literature, including Manski’s bounds, bounds based on threshold crossing models, and bounds based on the Local Average Treatment Effect (LATE)...

We employ quantile regression fixed effects models to estimate the income-pollution relationship on <italic>NO</italic> _{<italic>x</italic>} (nitrogen oxide) and <italic>SO</italic> ₂ (sulfur dioxide) using U.S. data. Conditional median results suggest that conditional mean methods provide too optimistic estimates about emissions reduction for...</italic>
