Last time I was here, I had a lot of fun teasing American libertarian readers, at least until the earthquake brought my guest blogging to an abrupt halt.
Support for liberty is a lot like support for GMO-free food. If you survey people, they’ll tell you how much they love it. They might even tell you it’s the most important thing in the world for them. But make them pay $0.50 extra to have it and they’ll choose the next product on the shelf. A few pay extra for the GMO-free tags, but if you’d probably be disappointed if you launched a GMO-free brand based on a survey of how much people claimed to hate genetically modified foods.
Jason Sorens and William Ruger have done great work in showing the substantial differences in experienced freedom across the 50 US States. A lot of libertarians live in New York; New York tends to come last in these surveys. Moving someplace that doesn’t keep trying to ban large sodas would mean giving up easy access to Broadway shows. It’s fine to be a pluralist and to weigh Broadway shows against personal liberties in some great personal utilitarian calculus, but it’s not exactly consistent with ‘Live Free or Die’ rhetoric.*
Absolute differences across American states are perhaps not large enough to make it worth moving. But if that’s the case, what are we to make of libertarian activism in the less-free states? It’s exceptionally unlikely that even the most effective activist in New York could move the state more than a point or two in the ordinal rankings, but that same person could take an oil job in North Dakota and move from worst to first while working there to help make North Dakota even better.
I’ve also argued, and often, that American libertarians should consider moving to New Zealand, which ranks first in the worldwide index weighing civil and economic freedoms. Why not choose to live free, or as free as is possible in the current world?
The Honours thesis I’m supervising this year will examine the price of liberty. The international ranking above gives a nice cross-sectional snapshot of differences in liberty across countries. Some of the measures can be extended backward in time. My student, Chris Read, is going to add these measures to international migration data to estimate the elasticity of migration flows to measured liberty and compare that elasticity to things like expected income differences across countries. Most people are messy pluralists; I’m really curious to see how things here pan out. Hopefully by the end of it, we’ll be able to say “A unit increase in civil liberties, all else equal, has about the same effect on inbound migration as a $X increase in median income.” That X will be close to a revealed preference measure of the price of freedom.
Later this week, I’ll post reassessing some of my Kiwi-enthusiasm in light of the post-earthquake policy experience. I’ve been pretty disappointed with how things here have panned out. We are not as far outside of the asylum as I had thought.
* I count myself as a messy pluralist of this sort too; I’m not trying to disparage it! Freedom matters, other stuff matters too.
