Consumer Welfare and Inefficiency Among Regulated Industries

While the issue of efficiency on the side of production is still not a settled question, it is generally agreed that competition is more conductive to efficiency—both allocative and X—than monopoly. When the monopoly is regulated, i.e., receiving a rate of return less than it would if left unregulated but greater than the market rate of return, both allocative and X-inefficiency result. Since the degree of inefficiency amounts to a tax on consumers, the question of inefficiency in production has a twin companion in the form of consumer welfare losses. This is particularly true for many public utilities upon which low income families spend a large proportion of their income. The quasi tax that the regulated monopolist exacts neither generates a flow of public goods nor increases returns to shareholders. It is a particularly burdensome levy because the rate structure is highly regressive.
