The effects of government transfer programs such as unemployment insurance and welfare assistance on strikes were studied by analyzing state-level data on strike frequency from 1960 through 1974. Effects were estimated by using ordinary least squares regression, supplementing traditional models of strike activity with measures of transfer program characteristics. No support was found for the claim that Aid to Families with Dependent Children, food stamps, or general assistance affect strikes. However, evidence was found linking unemployment insurance payments to the frequency of strikes, with a more generous unemployment insurance program being associated with a higher strike frequency. No conclusions were possible on whether unemployment insurance programs affect either strike duration or the number of workers involved in strikes. Either there are no effects or the methods used were not precise enough to measure the effects of two states' (New York and Rhode Island) provision of unemployment compensation to strikers after a waiting period of 7-8 weeks.
