GGSY_data.dta: This file contains data from an artefactual field experiment in Malawi that measures time preferences and revision behavior. The sample consists of several hundred wife-husband pairs in rural Malawi. Intertemporal choices are elicited by adapting Andreoni and Sprenger's (2012) convex time budget method, with large real stakes (roughly a month's wages). Subjects decide five potential allocations of money to be disbursed at two points, 61 or 91 days, in the future for the corresponding interest rates: 10%, 25%, 50%, 75%, and 100%. A subset of these subjects was revisited some time prior to the first disbursement at t=61 days and given the opportunity to revise their allocation between sooner or later. Dataset contains N=10,710 decisions (i.e., five allocations and associated interest rate for 2,142 subjects in the study).
The dataset “GGSY_data_long” contains the exact same data but in a different format. Participants are asked to make a series of 5 decisions, where the only variable that is changed is the interest rate. The dataset “GGSY_data_long” contains 10,710 observations, where each observation one of these decisions (2,142 individuals * 5 decisions = 10,710 observations).
