Puerto Rico became an insular possession of the United States following the Spanish-American War in 1898. Shortly thereafter the island was brought within the monetary and tariff structures of the United States, and mainland capital began to flow into the island, especially in the form of investments in the sugar industry. These factors were mainly responsible for shaping the Puerto Rican economy and for tying it closely to the economy of the United States.

2 Free trade was actually established on July 25, 1901, by presidential proclamation, after the insular legislature had provided a system of local taxation in accordance with the provisions of the Foraker Act. Until that date, goods shipped between the island and the mainland were subject to a tariff amounting to 15 per cent of the regular tariff schedule then in effect on trade between the United States and foreign countries. The customs duties collected during that period were used to finance insular government operations.
3 This, of course, provides only a very rough approximation, considering the difficulties of estimating the “true” value of many types of investments. The study of Gayer, Homan, and James includes a careful estimate of the returns on absentee investment in the sugar industry. For the years 1923 through 1935, the total earnings of the three major American-owned companies were estimated to have been 10.2 per cent on the average annual investment in Rico, Puerto; The Sugar Economy of Puerto Rico (New York: Columbia University Press, 1938). pp. 152–56.Google Scholar
4 There is no doubt, however, that the relative gains and losses for Puerto Rico from its tariff assimilation with the United States shows a decided gain for the island. For a discussion of this point, see United States Tariff Commission, “Puerto Rico's Economy,” pp. 106–9.
