…past experience has confirmed the nonmonetary impact of a minimum-wage hike on workers, not only in reduced fringe benefits but in increased work demands and decreased job training. For example:
- When the minimum wage was increased in 1967, economist Masanori Hashimoto found that workers gained 32 cents in money income but lost 41 cents per hour in training — a net loss of 9 cents an hour in full-income compensation.
- Similarly, Linda Leighton and Jacob Mincer in one study, and Belton Fleisher in another, concluded that increases in the minimum wage reduce on-the-job training and, as a result, dampen long-run growth in the real incomes of covered workers.
- Additionally, North Carolina State University economist Walter Wessels determined that a wage increase caused New York retailers to increase work demands. In most stores, fewer workers were given fewer hours to do the same work as before.
- More recently, Mindy Marks found that the $0.90 per hour increase in the federal minimum-wage rate in 1990 reduced the probability of workers receiving employer-provided health insurance from 66.2 percent to 63.1 percent, and increased the likelihood that covered workers would be reduced to part-time work by 26 percent.
Wessels also found that for every 10 percent increase in the minimum wage, workers lose 2 percent of nonmonetary compensation per hour. Extrapolating from Wessels’ estimates, an increase in the federal minimum wage from $7.25 to only $9.00 an hour would make covered workers worse off by 35 cents an hour.
And if the minimum wage were raised to $10.10 an hour, for example, the estimated 16.5 million workers earning between $7.25 and $10.10 could lose nonmonetary compensation more valuable than the $31 billion in additional wages they are expected to receive.
I would be skeptical or agnostic about some of those particular estimates, but surely the general point holds, and is hardly ever mentioned by advocates of hiking the minimum wage.
