A startup-quarter panel (`startup_qtr_panel.dta`) for 1980-2010 with time-varying information on startups that receive at least one patent during the sample period. Please note that observations up through 2017 are in the dataset because our dependent variables were forward looking relative to our independent variables and available after 2010.
