evidence: Minimum wages deliver earnings gains for some workers. [...] Economists describe the effect of minimum wages using the employment elasticity, which is the ratio of the percentage change in employment to the percentage change in the legislated minimum wage. For example, a 10% increase in the minimum wage reduces employment of the affected group by 1% when the elasticity is −0.1 and by 3% when it is −0.3. [...] Nearly two-thirds of the studies reviewed estimated that the minimum wage had negative (although not always statistically significant) effects on employment. Only eight found positive employment effects. Of the 33 studies judged the most credible, 28, or 85%, pointed to negative employment effects. These included research on Canada, Colombia, Costa Rica, Mexico, Portugal, the UK, and the US. In particular, the studies focusing on the least-skilled workers find stronger evidence of disemployment effects, with effects near or larger than the consensus range in the US data. In contrast, few—if any—studies provide convincing evidence of positive employment effects of minimum wages.
