In his study, Sabia (2015) found no evidence that minimum wage increases were associated with changes in overall state Gross Domestic Product (GDP). The differencein-difference-in-difference estimates showed that a 10% increase in the minimum wage
causes a 1%-2% decline in GDP generated by low skilled industries relative to more high
skilled industries. Moreover, the effect appears to be larger during the period of high
employment compared to low employment.
