In 2010, the Gulf Coast experienced the largest oil spill, the greatest mobilization of spill response resources, and the first Gulf-wide deepwater drilling moratorium in U.S. history. Taking advantage of the unexpected nature of the spill and drilling moratorium, I estimate the net effects of these events on Gulf Coast employment and wages. Despite predictions of major job losses in Louisiana -- resulting from the spill and the drilling moratorium -- I find that Louisiana coastal parishes, and oil-intensive parishes in particular, experienced a net increase in employment and wages. In contrast, Gulf Coast Florida counties, especially those south of the Panhandle, experienced a decline in employment. Analysis of accommodation industry employment and wage, business establishment count, sales
tax, and commercial air arrival data likewise show positive economic activity impacts in the oil-intensive coastal parishes of Louisiana and reduced economic activity along the Non-Panhandle Florida Gulf Coast.
