If Canada is divisible, then Quebec is divisible. If Quebec is divisible, then Montreal is divisible.
Gabriel Mihalache tries to pull the old reducto ad absurdam on my contention that nations are places, and the implication that quality-of-place considerations might lead to deviations from the traditional case for free trade. He writes:
Why not ask… if localities can benefit from these deals, this industrial policy—to quote another skeptic—then why not apply the same idea to streets, town squares, and beyond? — Maybe we should have a sort of street prefect, with his own budget, ready to subsidize business start-ups on his street?
Why allow for free movement between 1st Avenue and 5th Avenue? Maybe 1st Avenue could benefit from some regulation or from offering subsidies? Why not?
To which I answer enthusiastically, "why not indeed!" Shopping malls are places too. Shopping mall developers often want big-name retailers as "anchor stores", so they offer national chains great deals on rent, and sometimes sweeten the deal with cash. This might seem economically foolish, at first glance. But the subsidy turns out to be small compared with the increased certainty that the mall will attract customers, and the higher rents boutiques will pay to sit between popular behemoths.
Malls are hardly a unique example. Most commercial real-estate owners will offer discounts to tenants they consider particularly "desirable", whose presence will in some hard-to-pin way increases the value of the property they have on offer.
People who live who live on nice streets often spend a great deal of money to maintain the exteriors of their homes, the quality of their lawns and gardens, etc. Part of this one can chalk-up to "consumption" — people take pleasure in having a nice spaces. But a lot of this represents a kind of informally coordinated public investment, enforced by social norms. The value of properties is contingent in part on the niceness of the street, and everyone is expected to do their part. Some neighborhoods are developed as mini nanny states, with coercive regulations one must adhere to as a homeowner in order to ensure that residents don't shirk in maintaining (often uninspiring) "standards". Neighborhoods organized as condominiums have the power to tax and spend to maintain and enhance the quality of space. Lots of people are pleased to submit to all this. (I don't necessarily endorse these neighborhoods. The uptight, snooty ones make me go "ew". But hey, it's the free market in action!)
Maybe, but exactly like free trade, these deals have winners and losers (who, just as with free trade, won’t get compensated). Also, there’s the issue of the “relevant moral community”. (Do poor Chinese children enter into your welfare judgments?… and the like.)
Basically, this boils down to choosing between two patterns of winners and losers, which is a political choice. You can show, maybe, that with an utilitarian “social welfare” function, the “development deal” is preferable. But that’s a big “maybe”. And it’s still politics, so it’s not a matter of knowing something that the economists don’t.
I won't argue much with this, except to note that, just as with free trade, enhancements of place may create winners and losers, but large overall gains. Many shopping malls could not survive without subsidized anchors. Boutique owners might be unhappy to subsidize the rent of retailers with much deeper pockets than themselves, and some potential renters might be so pissed off they refuse to rent. Still, it's hard to argue that there isn't a large overall gain from the subsidy.
A condominium association might decide that common spaces need to be repainted annually, and fees will be increased to cover the expense. Some homeowners undoubtedly will consider the fresher halls to be worth less than the money they pay out. Given heterogenous and uncertain utility functions, one objector's sheer misery might be enough to outweigh any gains to other tenants. But, under ordinary assumptions, if the vast majority enthusiastically support the change, we usually presume overall gains. The case for overall gains is at least as clear as in the argument for free trade.
Of course, if leadership of the condominium association has been hijacked by unrepresentative busy-bodies, or by a board member whose kid brother is a painter, large overall losses might result. But the possibility of agency problems oughtn't prevent us from considering potentially welfare-enhancing subsidies. Both action and inaction are potentially flawed choices. In the real world, we do our best to control agency costs, but we still make decisions.
I do want to emphasize that I am playing with ideas here, and not quite endorsing the idea of legitimizing state subsidy as a normal part of international trade. It's a surprisingly interesting idea, and one can make the case for it in very "orthodox" terms. (If one does so, one finds that what is destructive of overall welfare is to abstain from subsidizing!) But the agency problems are, to say the least, daunting.
Regardless, people like Don Boudreaux who want to argue for traditional free trade based on the example of trade within the United States need to grapple with the historical fact of ubiquitous subsidy. And I'm not just playing when I suggest that any model of trade that looks only at gains and losses to individuals without considering quality of place is simply inadequate as a basis for policy.
