The study, which updates a Goldman Sachs analysis to include data from April and May, shows that the 13 states that increased their minimum wages on Jan. 1 have had stronger employment growth than the 37 states that didn’t. The study compared average employment during the first five months of 2014 with the last five months of 2013.
The average change in payrolls in the 13 states that increased their minimum wages was 0.99% vs. 0.68% in the other states.  On January 1, Connecticut, New Jersey, New York and Rhode Island boosted their pay floors as a result of legislation. The other nine states – Arizona, Colorado, Florida, Missouri, Montana, Ohio, Oregon, Vermont and Washington – automatically raised their minimums by smaller amounts based on inflation.
