Resumen
The Panel Studies of Entrepreneurial Dynamics (PSED I and PSED II) are nationally representative longitudinal surveys of individuals in the United States who are in the process of starting businesses. These nascent entrepreneurs have been followed for three to four years (PSED I, N = 1,261, over 6,000 variables), or for six years (PSED II, N = 1,214, over 8,000 variables). As of this writing there are over 150 publications based on the PSED, but there could be even more if some of the critical data cleaning and data combining instructions were widely available. This article presents code (both SPSS and STATA) that can be used to check on the inclusion criteria, to renormalize weights for subgroup analysis, and to combine the data for PSED I with those for PSED II.
