Joel Waldfogel asks, Which country is the best colonizer?:
Feyrer and Sacedote’s key findings are that the longer one of the islands spent as a colony, the higher its present-day living standards and the lower its infant mortality rate. Each additional century of European colonization is associated with a 40 percent boost in income today and a reduction in infant mortality of 2.6 deaths per 1,000 births.

To be sure, Europeans have not always been benevolent masters. Before the Enlightenment, they tended to view natives as savages who were better off dead than not baptized. After about 1700, however, attitudes began to change. While 16th-century explorers like Magellan set out to spread Christianity as well as make money, later voyages, like those of English Capt. James Cook between 1768 and 1779, had more explicitly scientific aims. The experience of island colonies reflects the difference. When the authors divide the islands into those that were colonized in the centuries before 1700 and those that were colonized after, current island income is 64 percent higher per century for the post-Enlightenment group but only 11 percent higher per century for the pre-Enlightenment one. And, no, the effects don’t appear to stem from the replacement of decimated low-income native populations with higher-income Europeans.The authors also compare the experiences of separate Pacific islands with eight different colonizers: the United States, Britain, Spain, Denmark, Portugal, Japan, Germany, and France. Their verdict is that the islands that are best off, in terms of income growth, are the ones that were colonized by the United States—as in Guam and Puerto Rico. Next best is time spent as a Dutch, British, or French colony. At the bottom are the countries colonized by the Spanish and especially the Portuguese.
There is no disputing that thousands died in the wake of European explorers’ discovery of the New World. That’s bad. But we can still give a small cheer for Columbus, because European colonization brought riches in its wake.
