Healthcare and Competitiveness

Greg Mankiw's Blog: Healthcare and Competitiveness:

"Ultimately, what matters to firms is the compensation they pay workers. The composition of compensation between cash wages and fringe benefits like healthcare does not matter for the firms' costs of production. In short run when cash wages are sticky, the cost of healthcare may affect competitiveness: Lower costs of fringe benefits would reduce compensation and thus reduce firms' cost of production. But in the long run, compensation is set by supply and demand in labor markets. If more compensation is paid in the form of fringe benefits like healthcare, less is paid in the form of cash. And if less is paid in fringes, more is paid in wages.*

Let me put the point in the context of General Motors: If, for example, the U.S. taxpayer were to assume all the workers' healthcare costs through a policy of national health insurance, GM would immediately become more competitive. Because cash wages would not be immediately renegotiated, compensation paid by the firm would fall, so costs would fall. But in the longer run, the workers via their union would most likely not be satisfied seeing GM pay lower compensation, so cash wages would start rising. (Those higher wages would help workers pay the higher taxes that would be needed to finance the national health insurance). GM would lose the competitive advantage it temporarily enjoyed."
