Moreover, much recent research (via Think Progress) shows no "job killing" effects from raising the minimum wage. As originally shown by David Card and Alan Krueger, there was strong evidence of "publication bias" in the studies underlying the former economists' consensus that the minimum wage reduced jobs. That is, economics journals tended to prefer to publish studies with statistically significant results and not publish those showing no effect from the minimum wage. Researchers thus adjusted their statistical specifications until they achieved statistical significance, thereby generating a mass of studies that all barely reached statistical significance despite larger volumes of data which should have produced stronger results. As the Schmitt paper emphasizes, more recent studies of studies ("meta-analysis") continues to support the conclusion that the purported job killing effect was a mirage.
As I have pointed out before, cross-national comparisons of the minimum wage and unemployment rates also do not support the view that the minimum wage is the job killer Republicans claim it is. Indeed, as in my September 2011 post, nine OECD countries have higher minimum wages rates than the U.S. does on a purchasing power parity basis that adjusts for the cost of living, yet only two have higher unemployment rates (France and Ireland), while the U.K.'s unemployment rate is the same. The table below illustrates this and underscores the point that the minimum wage is a winner for the middle class.
|For 2011 real minimum wage at PPP, click on "statistics by theme," then "labour," then "Real hourly minimum wages," then adjust the series to "In US$ PPP." For unemployment, click on "statistics by theme," then "general statistics," then "key short-term indicators," then "harmonized unemployment rates."|
