Foreign legal systems probably affect your life as well. Many hospitals in the United States are insured through insurance companies incorporated in the Cayman Islands, a British Overseas Territory in the Caribbean that is better known to most people for its beaches and scuba diving than for providing insurance to health care providers. The extended warranty you bought on an appliance could be funded through a Turks & Caicos Islands company, another British Overseas Territory. And any insurance policy you buy from a US insurer is likely reinsured through a Bermuda-based (yet another British Overseas Territory!) reinsurer.
All of these are examples of the results of jurisdictional competition, which is the competition among jurisdictions to persuade people to bring legal business to them. The international version of this competition is little different from the domestic American version. In our federal system, states compete for economic activities by offering legal and business environments to attract entrepreneurs. Attractions include business courts (to speed resolution of disputes), business entities laws that cut the transaction costs of creating new businesses, low taxes, better infrastructure, and dozens more features of a business climate that are calculated to appeal to entrepreneurs. The main difference between the international competition for business and the domestic one is that in the former case, jurisdictions are primarily competing through their legal systems for the legal residence of businesses, while in the latter, states are trying to secure a physical presence of employers.
Many of the jurisdictions that are internationally successful in this the law market are small ones with some affiliation (past or present) with the United Kingdom. These jurisdictions are variously called “tax havens” (a term that was originally meant to conjure up a refuge from taxes, but became a slur intended to suggest they were cheating other places out of tax revenue); “offshore financial centers” (since many are islands); and, now, “international financial centers.” Depending on how you count, there are two to four dozen successful IFCs around the world, including independent countries such as the Bahamas, Liechtenstein, Malta, and Mauritius; territories affiliated with Britain, such as Bermuda, the Cayman Islands, Gibraltar, Guernsey, Jersey, and the Isle of Man; and the Cook Islands, which are in free association with New Zealand. As this partial list suggests, IFCs are present around the globe. What exactly do they do?
