University of California, Irvine economist David Neumark has examined more than 100 major academic studies on the minimum wage. He states that the White House claim "grossly misstates the weight of the evidence." About 85 percent of the studies "find a negative employment effect on low-skilled workers." A 1976 American Economic Association survey found that 90 percent of its members agreed that increasing the minimum wage raises unemployment among young and unskilled workers. A 1990 survey found that 80 percent of economists agreed with the statement that increases in the minimum wage cause unemployment among the youth and low-skilled. If you're looking for a consensus in most fields of study, examine the introductory and intermediate college textbooks in the field. Economics textbooks that mention the minimum wage say that it increases unemployment for the least skilled worker.
As detailed in my recent book "Race and Economics" (2012), during times of gross racial discrimination, black unemployment was lower than white unemployment and blacks were more active in the labor market. For example, in 1948, black teen unemployment was less than white teen unemployment, and black teens were more active in the labor market. Today black teen unemployment is about 40 percent; for whites, it is about 20 percent. The minimum wage law weighs heavily in this devastating picture. Supporters of higher minimum wages want to index it to inflation so as to avoid its periodic examination.
