The precondition nobody prices in

The Washington Examiner opens with a charming confession: the author and his brother were nearly banned from a Maryland shopping mall for the grave offense of riding an escalator the wrong way. He tells it as a small comedy of childhood mischief — but the anecdote points toward something I consider foundational. A mall, like a market fair, a trading floor, or an open street of shops, is not simply a collection of goods and prices. It is a governed space. The rule that you ride the escalator in the proper direction, that you do not menace the shopkeeper, that you do not take what you have not paid for — these rules are the invisible infrastructure upon which every voluntary transaction rests.

The invisible hand has an invisible framework

I am regularly invoked by those who wish to argue that markets require no oversight and no law — that the hand, being invisible, works by magic. I said no such thing. In The Wealth of Nations I was plain: the sovereign has an obligation to maintain an exact administration of justice, without which no man would feel secure enough to invest, to trade, or even to carry his goods to market. A shop that cannot protect its inventory from theft is not a free market; it is a subsidized hunting ground for those who prefer taking to trading. The costs of that disorder — higher prices, closed storefronts, reduced variety — fall with particular cruelty on the consumer of modest means, who cannot afford the private alternatives available to the prosperous.

The incidence of disorder falls on the poorest

This is the point that tends to escape the policy discussion. When retail losses from theft and harassment are tallied, merchants pass those costs forward in prices, or they exit the market entirely, leaving the neighborhood without a grocer, a pharmacy, or a hardware shop. The Washington Examiner's story, taken as inference from its lead, suggests that malls in certain localities have become contested spaces where ordinary commerce is disrupted. I would observe — as a matter of political economy, not of partisan sentiment — that the population most harmed by the withdrawal of retail from a neighborhood is the population that cannot simply drive thirty minutes to a safer alternative. Disorder is, in this precise sense, a regressive tax.

Justice is a public good, not a luxury

I argued in The Wealth of Nations that defense, justice, and certain public works are the proper charges of the sovereign — not because I distrusted private enterprise, but because these things are the preconditions of private enterprise. Justice, in particular, cannot be left to the individual trader to procure for himself; a system in which each shopkeeper must hire his own private force merely recreates, at greater expense and with far less impartiality, the function that a well-administered court and constabulary would perform for all. The merchant who lobbies against public expenditure on law enforcement, while quietly raising his prices to cover shrink, is enjoying a public good while refusing to pay for it — a species of free-riding I find no more admirable than the mercantilist who sought monopoly privileges at the consumer's expense.

The institutional question

Every story about commerce eventually resolves into an institutional question: what framework makes the exchange honest? In this case the answer is not complicated. It requires a constabulary that enforces the law impartially — not selectively, not brutally, but consistently. It requires courts that are accessible and swift enough that the small trader can seek redress without ruin. And it requires a public culture, transmitted by education and by the ordinary experience of civic life, in which the equal dignity of every person in that marketplace — shopper, clerk, owner, and bystander alike — is taken as the foundation of the whole enterprise. Without those things, the invisible hand grasps at nothing.
