Until economists actually studied the question it was assumed that raising the minimum wage would always result in some unemployment of the minimum wage workers. But not because the demand for these workers decreased as dismal and colorado say that the demand for workers goes down as the price, the wages, goes up. There are many problems with this rational, not the least of which is if employers hired employees based on supply and demand, that is their price, then any increase in wages would result in unemployment, not just increases for minimum wage workers. But in my substandard basic economics employers only hire workers when they have profitable work for them to do.
This assumption that minimum wage workers would have to be laid off if their wages increased was based on the neoclassical economics theory of "marginal productivity." This theory says that supply and demand will drive the price of the product produced down to cost of the marginal product, the cost without profit of the very last product that can be produced. That the employers will be forced to hire workers until the wages that they have to pay to hire the workers equals exactly the Iabor cost of their marginal product, the product that their labor adds to the production.
Or put simply and slightly incorrectly as, no one will pay more for an hour of work than it adds to their income. Or that if the labor rate increases beyond what is earned from the marginal product added by the added labor, then the employer will fire the worker's whose marginal product is now losing money.
There is nothing in neoclassical economics that supports dismal's and colorado's assertion that there is a demand for labor based on its costs and not how much the added labor will add to production and to the incomes of the owner.
There are possibly some exceptions that can be cited where workers have been hired when it costs the owners all or part of new hires wage. But we don't make economic policies that affect the entire economy based on exceptions.
But on the other side of the coin, whether an increase in wages will result in lay offs and widespread unemployment, there are three possible scenarios,
- dismal's and colorado's one where workers wages exceed the owners' tolerance for the wages that they will pay, even if the owners are making enough money from the sales of the marginal product provided by the workers laid off. We could call it the Coors' scenario where the owners were so blinded by their conservative ideology that they were willing to lose earnings to keep out the unions.
- That the added wages force profitable businesses to become less profitable.
- That the added wages force the owners to lose money to pay the higher wages.
Once again, like all of the questions regarding economics on this board, this question comes down to one of, how much, how fast and why? In this case, how much and how fast the minimum wage is raised. Obviously, if you raise the minimum wage to a hundred dollars an hour overnight all three of the above will be true.
Likewise, if you raise it ten cents over two years it won't have any impact. On anyone, not even the people who earn the minimum wage.
Why is easily answered. We need to address the imbalance in the economy we started doing thirty five years ago to redistribute income from wages into profits. This has resulted in a large part of the income inequality that you see today. Even if you take the rather improbable position that the supply side economics or Reaganomics policies didn't do what they intended to do, to intentionally increase income inequality to increase the money available for investment, rather that these policies failed, and that unknown and, apparently, unknowable factors caused the current income inequality that started about the same time as the Reaganomics started, then there is no obvious reason to continue and to replace them with policies intended to reverse the income inequality.
This would seem to be true if you believe that we don't have high income inequality right now because we can't reliably determine who makes what income. Or that we have had the benefits promised for Reaganomics but for some reason economists are unable to do what they were able to do in 1980, to add up the costs of all of the products sold in the country, that they can no longer find out who is unemployed and why and that we can no longer figure out how much income people now earn.
Or that income inequality doesn't harm the economy or individuals. Or that people still get promotions and raises. Or that the economy rewards CEO's, other corporate managers, bankers, college graduates who aren't teachers, coupon clippers and other passive income earners, stockbrokers, stockholders, insurance companies, real estate tycoons, hedge fund managers, payday and car title loan operations, pawn shops, hospitals and doctors, etc. with much more income than they did in 1980 now because they earn it, that they deserve it or because of technical changes in the economy that had nothing to with the Reaganomics policy changes or with any of the legislation passed by a Republican Congress or from a 5 to 4 conservative SCOTUS decision or by the now well worn virtual galaxy of other economic factors that can't be named.
