Richard McKenzie reports:

…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.
