Optimal data collection for randomized control trials
Carneiro, Pedro; Lee, Sokbae; Wilhelm, Daniel - 2016
In a randomized control trial, the precision of an average treatment effect estimator can be improved either by collecting data on additional individuals, or by collecting additional covariates that predict the outcome variable. We propose the use of pre-experimental data such as a census, or a...

New estimates of the value of a statistical life using air bag regulations as a quasi-experiment
Rohlfs, Chris; Sullivan, Ryan; Kniesner, Thomas J. - 2012
Due to Federal regulations, automobile air bag availability was a model-specific discontinuous function of model year for used vehicles in the 1990s and early 2000s. We use these discontinuities and the gradual increase in the supply of air bags to trace out the demand curve for air bags and the...
