At Coyote Blog, Warren Meyer discusses how real world service companies that employ a lot of minimum wage workers are likely to respond when the minimum wage is raised:
When I discuss this with folks, they will say that the increase could still come out of profitability — a 5% margin could be reduced to 3% say. When I get comments like this, it makes me realize that people don’t understand the basic economics of a service firm, so a concrete example should help. Imagine a service business that relies mainly on minimum wage employees in which wages and other labor related costs (payroll taxes, workers compensation, etc) constitute about 50% of the company’s revenues. Imagine another 45% of company revenues going towards covering fixed costs, leaving 5% of revenues as profit. This is a very typical cost breakdown, and in fact is close to that of my own business. The 5% profit margin is likely the minimum required to support capital spending and to keep the owners of the company interested in retaining their investment in this business.
Now, imagine that the required minimum wage rises from $10 to $15 (exactly the increase we are in the middle of in California). This will, all things equal, increase our example company’s total wage bill by 50%. With the higher minimum wage, the company will be paying not 50% but 75% of its revenues to wages. Fixed costs will still be 45% of revenues, so now profits have shifted from 5% of revenues to a loss of 20% of revenues. This is why I tell folks the math of absorbing the wage increase in profits is often not even close. Even if the company were to choose to become a non-profit charity outfit and work for no profit, barely a fifth of this minimum wage increase in this case could be absorbed. Something else has to give — it is simply math.
The absolute best case scenario for the business is that it can raise its prices 25% without any loss in volume. With this price increase, it will return to the same, minimum acceptable profit it was making before the regulation changed (profit in this case in absolute dollars — the actual profit margin will be lowered to 4%). But note that this is a huge price increase. It is likely that some customers will stop buying, or buy less, at the new higher prices. If we assume the company loses 1% of unit volume for every 2% price increase, we find that the company now will have to raise prices 36% to stay even both of the minimum wage increase and lost volume. Under this scenario, the company would lose 18% of its unit sales and is assumed to reduce employee hours by the same amount. In the short term, just for the company to survive, this minimum wage increase leads to a substantial price increase and a layoff of nearly 20% of the workers. Of course, in real life there are other choices. For example, rather than raise prices this much, companies may execute stealth price increases by laying off workers and reducing service levels for the same price (e.g. cleaning the bathroom less frequently in a restaurant). In the long-term, a 50% increase in wage rates will suddenly make a lot of labor-saving capital investments more viable, and companies will likely substitute capital for labor, reducing employment even further but keeping prices more stable for consumers.
As you can see, in our example we don’t need to know anything about bargaining power and the fairness of wages. Simple math tells us that the typical low-margin service business that employs low-skill workers is going to have to respond with a combination of price increases and job reductions.
