Living wage campaigns have succeeded in about 100 jurisdictions in the United States but have also been unsuccessful in numerous cities. These unsuccessful campaigns provide a better control group or counterfactual for estimating the effects of living wage laws than the broader set of all cities without a law, and also permit the separate estimation of the effects of living wage laws and living wage campaigns. We find that living wage laws raise wages of low-wage workers but reduce employment among the least-skilled, especially when the laws cover business assistance recipients or are accompanied by similar laws in nearby cities.

Many features of living wage laws may influence the strength of their effects on wages and employment of low-skill individuals. Echoing past research, business assistance living wage laws generate stronger wage increases and employment reductions than contractor-only laws. But broader enforcement or implementation and geographic concentration of living wage laws also appear to strengthen their effects. Finally, geographic concentration may be more significant than the distinction between business assistance and contractor-only living wage laws.

Nearly 100 cities and local governments in the United States passed living wage laws since the mid-1990s. The central goal of living wages is to reduce poverty, yet they may fail to do so because of disemployment effects. We summarize and critique the existing research on the effects of living wages on wages, employment, and family income, emphasizing common findings, points of disagreement, and important questions for future research. The evidence thus far points to wage increases as well as employment losses for the least-skilled although there is disagreement about the employment effects but on net some beneficial distributional effects. The evidence also points to efficiency wage-type effects of living wage laws that may offset some of the adverse impacts on employers.

This paper explores the effects of living wages on low-wage workers and low-income families. First, we update our earlier analyses, using data for 1996-2002, and address a number of criticisms of those analyses. We confirm our earlier findings that business assistance living wage laws boost wages of the lowest-wage workers, at the cost of some disemployment, but on net reduce urban poverty. Second, we expand the analysis of distributional effects beyond looking just at the poverty threshold. We do not find that living wages increase the depth of poverty among families that remain poor, and we find that families somewhat below and somewhat above the poverty line are also helped by living wages. Finally, we suggest that the poverty reductions generated by living wages may stem from income ga...
