I need to use the data from https://admin.nber.org/data/current-...rvey-data.html for March 2018. It is downloaded as a .zip file instead of .dta. I found someone else asking this same question and followed instructions using 7-zip but I get the same error when I try to open the file: ' not Stata format" Is there any easy way to get this file to open in STATA? Any help is greatly appreciated.
