This paper proposes a way of using observational pretest data for the design of experiments. In particular, this paper trains a random forest on the pretest data and stratifies the allocation of treatments to experimental units on the predicted dependent variables. This approach reduces much of...

This dissertation presents four independent papers that advance experimental methods and test theories on saving using experimentally elicited characteristics. The first two papers test two behavioral theories on precautionary saving based on the characteristics loss aversion and prudence by...
