Remember all the old Canadian nationalists? The ones who said that the (Canada-US) Free Trade Agreement would destroy Canadian culture? The ones we economists defeated back in the 1988 election? I'm beginning to wish we hadn't defeated them quite so thoroughly.
They were wrong. But they sorta, kinda, did have a point. Social/economic institutions are endogenous. They are not part of the unchanging geological landscape. Social/economic institutions are part of what people do; they are part of how people interact with each other, and expect others to interact with them. And, at least in principle, there is no reason why those social/economic institutions should be exogenous with respect to our imports and exports. And there is, or there used to be, a whole school of Canadian economics that pushed exactly that idea. So if you could make a reasonable case that the FTA and importing or exporting more apples would cause Canadian social/economic institutions to become, well, like North Korea, then OK. All that guff about comparative advantage and economies of scale and the gains from trade wouldn't be very convincing.
