# How The Minimum Wage Can Kill Job Growth Without Eliminating Current Jobs

How The Minimum Wage Can Kill Job Growth Without Eliminating Current Jobs by David R. Henderson, Foundation For Economic Education

Wage floors impact future capital investment as much as current labor costs

Jonathan Meer and Jeremy West have found that increases in the minimum wage destroy jobs, not so much by destroying current jobs as by reducing the growth rate of new jobs.

Li Lu And Greenwald On Competitive Advantages And Value Investing

In April, Li Lu and Bruce Greenwald took part in a discussion at the 13th Annual Columbia China Business Conference. The value investor and professor discussed multiple topics, including the value investing philosophy and the qualities Li looks for when evaluating potential investments.

That makes sense if employers’ investments in capital are even partially irreversible, that is, if some costs of capital investment are sunk, as seems plausible.

Here’s a simple numerical example to illustrate the point.

Imagine that an employer is contemplating investing \$100K in the price and installation of a piece of machinery that he expects to last 5 years. Assume for simplicity that once it is bought and installed, the salvage value is zero. (Numbers greater than zero work also, but complicate the analysis, with no additional insight.)

Assume that the current minimum wage is \$7 an hour and that the employer contemplates hiring a worker for a standard work year of 2,000 hours. At that wage rate, he can find a suitable worker. Assume that there are no other components of the pay package and that there are no other costs of production. Assume that the employer expects to be able to sell the annual output from the machine/worker combination for \$37,000. Assume, for simplicity, a zero real interest rate. (That, by the way, is often a bad assumption but in recent years, it is not far off.)

If the employer expects no increases in wages over the next 5 years, will he make the investment? Yes.

The reason is that his costs over the 5 years are \$100K for equipment and \$70K for labor, for a total of \$170K. His revenues are \$185K. Net profit: \$15K.

But now imagine that after 2 years of operating profitably, the employer faces a minimum wage of \$10 an hour.

Had he known this in advance, he would have known that his cost of labor over the 5 years would have been \$14K + \$14K + \$20K + \$20K + \$20K = \$88K. So his total costs would have been \$188K. Compare that to the \$185K of revenue and the employer would not have invested.

But the employer has invested. The equipment cost is sunk. Will the employer continue? Yes, he will. The reason: he now compares \$20K of annual labor cost to \$37K of annual revenue and finds that it is worthwhile to continue.

So he will not lay off the labor.

However, other potential employer/investors facing the same numbers will not make the investment. So whatever growth rate of jobs there would have been will not come about. The growth rate will be lower.
