Center for Economic & Policy Research - At the beginning of 2014, 13 states increased their minimum wage. Of these 13 states, four passed legislation raising their minimum wage (Connecticut, New Jersey, New York, and Rhode Island). In the other nine, their minimum wage automatically increased in line with inflation at the beginning of the year (Arizona, Colorado, Florida, Missouri, Montana, Ohio, Oregon, Vermont, and Washington state).
As CEPR noted in March and April posts, economists at Goldman Sachs conducted a simple evaluation of the impact of these state minimum-wage increases... The GS analysis found that the states where the minimum wage went up had faster employment growth than the states where the minimum wage remained at its 2013 level.
When we updated the GS analysis using additional employment data from the BLS, we saw the same pattern: employment growth was higher in states where the minimum wage went up. While this kind of simple exercise can't establish causality, it does provide evidence against theoretical negative employment effects of minimum-wage increases.
