The boll weevil is America's most celebrated agricultural pest. We analyze new county-level panel data to provide sharp estimates of the time path of the insect's effects on the southern economy. We find that in anticipation of the contact, farmers increased production, attempting to squeeze out one last large crop. Upon arrival, the weevil had a large negative and lasting impact on cotton production, acreage, and especially yields. In response, rather than taking land out of agricultural production, farmers shifted to other crops. We also find striking effects on land values and population movements.
A number of talented students, including Jeffery Graham, Pablo Reynolds, and Elise Perez, have contributed to advancing this research. Shelagh Matthews Mackay, whose attention to detail and insights have left a positive mark, deserves special mention. We would also like to thank participants at the presentations at the NBER-DAE meetings, the Business History Conference, and at the University of Michigan and UCLA, as well as the editors of this Journal and four referees for their comments.
