A final line of argument is that these public assistance programs have become de facto subsidies for low-wage employers. For a program to be a subsidy for an employer, it needs to lower wages. Is this plausible for the public assistance programs considered? I think it is for the EITC [Earned Income Tax Credit], but not for other programs. Depending on where one is on the EITC schedule, that policy can increase work incentives. And there is a lot of empirical evidence showing EITC encourages labor force participation. An unintended consequence of that labor supply response, however, is that employers capture some of the tax subsidies. This can happen in a simple supply and demand framework, where an increased labor supply to the market drive wages down. This can also happen in a bargaining context where the size of the bilateral surplus expands from lower taxes, and employers capture some of this increased surplus. Work by UC Berkeley’s Jesse Rothstein suggests that for every $1 of transfer to workers using the EITC, post-tax income rises only by $0.73 because of employer capture.
But what about other programs like food stamps or housing assistance? These means tested public assistance programs are not tied to work, and we should not expect them to lower wages. Let’s take food stamps, which are available to eligible families whether or not a family member works or not. Indeed, when people are not working, they are more likely to be eligible for food stamps since their family incomes will be lower. Therefore, SNAP [Supplemental Nutrition Assistance Program] is likely to raise, and not lower a worker’s reservation wages — the fallback position if she loses her job. This will tend to contract labor supply (or improve a worker’s bargaining position), putting an upward pressure on the wage. Whether or not wages are increased is an empirical matter: there is evidence that the initial roll-out of the food stamps program across counties in the 1970s lowered work hours, consistent with an increase in the reservation wage. The key point is that it is difficult to imagine how food stamps would lower wages. And if they don’t lower wages, they can’t be thought of as subsidies to low wage employers. The same logic applies to other means tested programs like energy or housing assistance. Moreover, these conclusions hold in a wide array of models of the labor market, including ones that emphasize bargaining or efficiency wage concerns.
