As a territory of the United States, Puerto Rico enjoys the benefits of key U.S. legal, monetary, security, and tariff systems, and its residents are U.S. citizens. In the decades following World War II, Puerto Rico emerged as one of the world's fastest-growing economies. From 1950 to 1970 per capita income nearly doubled as a percentage of the U.S. average, making the island the richest economy in Latin America. Since the mid-1970s, however, labor force attachment has declined, economic growth has slowed, and the island's living standards have fallen further behind those on the mainland. Today more than half of all Puerto Rican children live below the U.S. poverty level. Why did Puerto Rico's economic progress stall? And more important, what can be done to restore growth? A number of overlapping concerns& #151;labor supply and demand, entrepreneurship, the fiscal situation, financial markets, and trade& #151; -are at the heart of its economic difficulties. This is a companion volume to Restoring Growth: The Economy of Puerto Rico (Brookings, 2006), in which economists from Puerto Rico and the United States examine the island's economy and propose strategies for sustainable growth. This monograph summarizes the analyses published in that volume and presents a set of policy recommendations to increase employment, improve education, upgrade infrastructure, and fix government finances.
