Regular readers know that one of my main goals is to preserve and promote tax competition as a means of restraining the greed of the political class. Heck, I almost wound up in a Mexican jail because of my work defending low-tax jurisdictions.
As you can imagine, it’s difficult to persuade politicians. After all, why would they support policies such as fiscal sovereignty and financial privacy that hinder their ability to extract more revenue? So I try to educate them about the link between taxes and growth in hopes that they will understand that a vibrant economy also means a large tax base. And I specifically tell them that so-called tax havens play a very valuable role since they are an alternative source of investment capital for nations that have undermined domestic investment with bad tax policy.
I also explain to them that low-tax jurisdictions give companies some much-needed flexibility to maintain operations in an otherwise hostile fiscal environment. Let’s look at that specific issue by reviewing some of the findings from a study by two Canadian economists about tax havens and business activity. In the introduction to their study, they describe the general concern (among politicians) that competition between governments will lead to lower tax rates:
Increased mobility of goods and services is apt to give rise to an erosion of corporate tax bases in high-tax industrialized countries, a decline in tax revenues and a rise in competition among governments. Countries seeking to attract and retain mobile investment and the associated tax revenues may be induced to reduce tax rates below the levels that would obtain in the absence of mobility. In the view of some commentators, indeed, increased mobility can lead to a “race to the bottom” driving business tax rates to minimal levels, due to the fiscal externalities that mobility creates.
It certainly is true that tax competition has pressured politicians to lower tax rates, and the academic research shows that this is a good thing, notwithstanding complaints by leftists economists such as Jeffrey Sachs.
