A major reason for skepticism about open borders among many who are partially sympathetic is the fear that poor immigrants will vote for redistribution. Natives might benefit, on average, from their interaction with immigration in the market, but in the political arena, poor immigrants with little to lose will vote for higher taxes and government handouts, making natives worse off. To deny immigrants the vote would solve this problem in theory, but raises other philosophical issues about the meaning of consent of the governed, and in any case might not be politically sustainable. Opportunistic parties might hand out citizenship to immigrants who they hope will be their future constituency. Immigrants might also take advantage of their physical presence to agitate in the streets for the vote and/or directly for the government benefits they hope to win by it. In short, open borders will make government more redistributive.
But the logic of Tiebout competition points the other way. Tiebout (1956) famously argues that local governments will provide public goods efficiently if people are free to move among jurisdictions, and concludes that we can expect public goods to be provided more efficiently at the local level than at the national level. Caplan recently explained where Tiebout goes wrong: (1) local governments are not perfectly competitive but face downward-sloping demand curves for residence and so can extract monopoly rents; (2) emigrants can’t take their real estate with them so bad local governments will reduce property values; and (3) local governments aren’t for-profit corporations and don’t face the incentives that for-profit corporations do to give customers/residents what they want. All good points, but there’s still something to be said for “voting with the feet.” Local governments may not be profit-maximizing firms, but they still differ in their performance, and people do get some choice over what local public goods they want by deciding where to live. In the short run, local misgovernment may depress property values more than inducing migration, but in the long run, capital can be adjusted, and misgoverned places can revert to weeds while well-governed places teem with new high-rises. And local governments are still somewhat competitive.
In the Tiebout model, government provides public goods rather than engaging in redistribution. The people who choose to live in a location don’t mind paying for what the government does, because they regard the benefits as greater than costs. If not, they would move. The government might charge the rich more than the poor, if it’s still providing the rich value for money, and especially if the rich value local public goods more, in money terms, than the poor do, which is plausible, since they presumably get less marginal utility from a dollar but might not get less marginal utility from a statue in the park or clean air or good streetlights. But if the government charges the rich too high a price for local public goods, they’ll move to a jurisdiction with lower taxes, and explicit redistribution is ruled out by the exit option.
Garett Jones has pointed out that a comparison of state tax regimes with federal tax regimes seems to support (loosely) the Tiebout model. See “Can Progressivity Survive Exit?”:
I should note though, that while state taxation is regressive in percentages, it’s progressive in dollars. And that’s the point of my tweet: Higher earners pay more than lower earners even though they could leave. Perhaps some of that is altruism, but I suspect-without-proof that most of it is just that the rich (and middle class) buy more and better government services than the poor.It’s possible that progressive income taxation could coexist with voluntary competitive government. Maybe the high-skilled need to be near each other to produce a lot, so the locales preferred by the rich can tax that demand for proximity. The (not very progressive) New York City income tax comes to mind.But at the national level, I suspect that the reason the rich pay higher total tax rates is mostly because it’s hard to leave the nation. Easy targets.
Jones also points to the French government’s retreat on capital gains taxes as a victory for “[the] Tiebout [model against] progressivity” (I think that’s what the title of his post means). And here he entertains the suggestion that the fact that European tax systems are much less progressive than America’s is explained by Tiebout competition. Since the EU has open borders, wealthy elites can shop among jurisdictions. I don’t know enough about European tax politics to affirm or deny the causal link here, but it fits the theory. An international comparison of corporate tax rates also suggests that Tiebout competition is at work. From the Tax Foundation’s blog, here are “Corporate Income Tax Rates Around the World.”
Note that the US has the second-highest (after Japan) corporate income tax rate in the OECD. This is counter-intuitive, since ideologically the US has a reputation for being free-marketeer and pro-business, with a comparatively thin welfare state and less regulation. But if international Tiebout competition is at work, this pattern is sort of what you’d expect. The US is big and geographically isolated, so corporations based in the US won’t find it very easy to hop the border. European countries face steeper competition from other jurisdictions, so companies are relatively mobile.
Open borders would make international Tiebout competition a more effective force for disciplining governments’ redistributive impulses. But here I don’t mean primarily unilateral open borders, nor open borders with very poor countries. The US government is not likely to cut taxes on the wealthy for fear that they’ll emigrate to Rwanda, or even Mexico. But it might someday cut taxes to keep the wealthy from moving to Hong Kong, or Italy, or some yet-to-be-founded futuristic free charter city. If the right to emigrate were made a global reality, international Tiebout competition might start to matter a lot.

“The US government is not likely to cut taxes on the wealthy for fear that they’ll emigrate to Rwanda, or even Mexico. But it might someday cut taxes to keep the wealthy from moving to Hong Kong, or Italy, or some yet-to-be-founded futuristic free charter city.”
Well, the US is already the only country in the world which taxes based on citizenship instead of residence. And it is adopting increasingly aggressive measures to ensure that citizens abroad pay taxes and report assets: witness FATCA, which demands that every bank in the world figure out if there are US citizens (or green card holders) among their customers (including dual citizens or American emigrants who actually reside in the bank’s country and may have opened an account using a local ID card), or face 30% fines on all US-source payments.
Of course, this is justified in terms of “stopping the wealthy from getting rich in America and fleeing taxes”, but the real effect is to make life extremely difficult for middle class emigrants who earn all of their income in the countries where they actually live:
So I see very little likelihood that the US would cut taxes to keep the people from moving. They already get the best of both worlds: emigrants move out and stop using government services (and in many cases can no longer vote, because voter registration is tied to a US state), but the government can continue to tax them anyway for years until they qualify for naturalisation elsewhere and give up US citizenship.
Very interesting post with some good links.
I must concur with Eric’s comment. The US is the only nation besides Eritrea that taxes individuals on the basis of citizenship and not residency. This citizenship-based taxation regime (much admired by many states around the world) was unworkable until very recently. It was simply impossible for the US government to efficiently track (in fact it has no idea even today where most of them actually live) its emigrants and enforce this. What has changed is more aggressive enforcement using hundreds of newly hired “international” IRS agents and the attempt to put into place automatic information exchanges (like FATCA). This would mean that local banks would be required to report bank account information back to the home countries of immigrants living in their jurisdictions. This law voted by the US Congress was meant to apply only to US citizens living abroad but negotiations with other countries has led to promises of reciprocity by the US government. This would mean that local banks in the US would be also required to sort their customers by nationality and hand over their financial information to the home country fiscal authorities. This would make the implementation of citizenship-based taxation regimes feasible for those countries who do not yet have such systems.
So the question I have is how all this will impact global labor mobility. While there are treaties to mitigate double taxation, they do not eliminate it (and I should know because I pay taxes both to my home country, the US, France – my host country). There is also the issue of complex reporting requirements for individuals (even lower and middle income ones) that make compliance very costly in order to take advantage of what does exist to mitigate double taxation. This could create a world where potential emigrants face yet another burden (and costs) if they wish to live and work in another country. They could find themselves double-taxed or at the mercy of cross-border tax professionals who charge high rates for international tax situations which are only complex because they involve at least two countries. It is potentially a real barrier to exit. Not necessarily for the rich but for working people. It has already caused much turmoil among the American community abroad who are left with a series of unpalatable choices: move back to the US, pay taxes twice (and pay the high cost of compliance) or renounce US citizenship. Remains to be seen how many Americans contemplating moving abroad will give up the idea once they find out how onerous (and how far-reaching) the US tax burden really is. And what will happen if other countries decide to emulate the US and impose their own diaspora tax systems? I think this would be deadly for legal global mobility particularly among highly-qualified working migrants.
