A billionaire philanthropist has tasked you with designing and running a field experiment helping the extremely poor in a developing country. Describe one experiment that you think will have positive impacts. Give an economic intuition for why you expect the experiment to work. What economic theory or concept are you going to test? Then describe some practical challenges that might arise in a developing country. What are factors you need to consider that are different from the U.S.? How could that affect your design and your conclusions?
