Minimum wage policy was part of the SOTU address last night. As it turns out, 20 states plus DC have minimum wages higher than the federal level. CEPR notes that:
As of January 1, 2014, 13 states raised their minimum wage, with California set to follow suit with an increase to $9 in July. Of these 14 state increases, 9 are automatic adjustments based on indexing the value of the minimum wage to the cost of living, while 4 (NJ, CT, NY, RI) are the product of either ballot-measures or legislative action.
