Are free markets always the best? Of course not, and where’d we get that idea?

Ideas often trump reality, especially in law. In my career, Law and Economics, grounded in the principle that law works best when it serves some notion of economic efficiency, has grown from a rather small movement identified with the University of Chicago into perhaps the dominant legal theory in our law schools and among our more prominent judges. I’ve always thought, for a number of reasons, that the faith in “markets” on which Law and Economics is grounded is bunk. I’m plainly not alone. Tony Judt writes:

In the last thirty years, a cult of privatization has mesmerized Western (and many non-Western) governments. Why? The shortest response is that, in an age of budgetary constraints, privatization appears to save money. If the state owns an inefficient public program or an expensive public service—a waterworks, a car factory, a railway—it seeks to offload it onto private buyers.

The sale duly earns money for the state. Meanwhile, by entering the private sector, the service or operation in question becomes more efficient thanks to the working of the profit motive. Everyone benefits: the service improves, the state rids itself of an inappropriate and poorly managed responsibility, investors profit, and the public sector makes a one-time gain from the sale.

So much for the theory. The practice is very different. What we have been watching these past decades is the steady shifting of public responsibility onto the private sector to no discernible collective advantage. In the first place, privatization is inefficient. Most of the things that governments have seen fit to pass into the private sector were operating at a loss: whether they were railway companies, coal mines, postal services, or energy utilities, they cost more to provide and maintain than they could ever hope to attract in revenue.

For just this reason, such public goods were inherently unattractive to private buyers unless offered at a steep discount. But when the state sells cheap, the public takes a loss. It has been calculated that, in the course of the Thatcher-era UK privatizations, the deliberately low price at which long-standing public assets were marketed to the private sector resulted in a net transfer of £14 billion from the taxpaying public to stockholders and other investors.

To this loss should be added a further £3 billion in fees to the banks that transacted the privatizations. Thus the state in effect paid the private sector some £17 billion ($30 billion) to facilitate the sale of assets for which there would otherwise have been no takers. These are significant sums of money—approximating the endowment of Harvard University, for example, or the annual gross domestic product of Paraguay or Bosnia-Herzegovina.[2] This can hardly be construed as an efficient use of public resources.

In the second place, there arises the question of moral hazard. The only reason that private investors are willing to purchase apparently inefficient public goods is because the state eliminates or reduces their exposure to risk. In the case of the London Underground, for example, the purchasing companies were assured that whatever happened they would be protected against serious loss—thereby undermining the classic economic case for privatization: that the profit motive encourages efficiency. The “hazard” in question is that the private sector, under such privileged conditions, will prove at least as inefficient as its public counterpart—while creaming off such profits as are to be made and charging losses to the state.

The third and perhaps most telling case against privatization is this. There can be no doubt that many of the goods and services that the state seeks to divest have been badly run: incompetently managed, underinvested, etc. Nevertheless, however badly run, postal services, railway networks, retirement homes, prisons, and other provisions targeted for privatization remain the responsibility of the public authorities. Even after they are sold, they cannot be left entirely to the vagaries of the market. They are inherently the sort of activity that someone has to regulate.
