This study improves upon the Difference in Difference approach by examining exogenous shocks using a Generalized Difference in Difference (GDD) technique that identifies economic effects of hurricanes. Based on the Quarterly Census of Employment and Wages data, worker earnings in Florida counties hit by a hurricane increase up to 4 percent, whereas earnings in neighboring counties decrease. Over time, workers experience faster earnings and slower employment growth than workers in unaffected counties. Hurricanes have a greater impact in coastal and Panhandle counties, and powerful hurricanes have greater economic effects than weaker ones. Further, the GDD technique is applicable to analyze a wider range of exogenous shocks than hurricanes.
