States with a high percentage of farmers had substantially lower mobilization rates, and this explains a considerable share of the state variation in mobilization rates. The authors show that in states with greater war mobilization of men, women worked more after the war and in 1950, but not in 1940. This differential does not appear to be explained by other cross-state differences or possible demand factors, and is not present in the 1940 data nor does a similar trend recur in the decade of the 1950s. The authors interpret these differentials as labor supply shifts induced by the War. Acemoglu, Autor, and Lyle believe these cross-state changes in female employment were caused by greater participation of women during the war years, with some of those women staying on. War changed womens preferences, opportunities, and information about available work.
