Abstract
 

This paper puts forward suggestions that could improve the efficiency of field experiments as they are currently carried out in experimental economics. Two recommendations are made: (1) Prior to the actual study, economic field experiments should include sample size calculations that confirm that meaningful effects can be detected. (2) Economic field experiments should take advantage of the power of multi-factor experimental plans.
