Since the early 1990s, the United States has borrowed heavily from its trading partners. This paper presents an analysis of the impact of an end to this borrowing, an end that could occur suddenly or gradually. Modeling U.S. borrowing as the result of what Bernanke (2005) calls a global saving glut--where foreigners sell goods and services to the United States but prefer purchasing U.S. assets to purchasing U.S. goods and services--we capture four key features of the United States and its position in the world economy over 1992-2012: (1) in the model, as in the data, the U.S. trade deficit first increases, then decreases; (2) the U.S. real exchange rate first appreciates, then depreciates; (3) the U.S. trade deficit is driven by a deficit in goods trade, with a steady U.S. surplus in service trade; and (4) the fraction of U.S labor dedicated to producing goods--agriculture, mining and manufacturing-- falls throughout the period, Using this model, we analyze two possible ends to the saving glut: an orderly, gradual rebalancing and a disorderly, sudden stop in foreign lending as occurred in Mexico in 1995-96. We find that a sudden stop would be very disruptive for the U.S. economy in the short term, particularly for the construction industry. In the long term, however, a sudden stop would have a surprisingly small impact. As the U.S. trade deficit becomes a surplus, gradually or suddenly, employment in goods production will not return to its level in the early 1990s because much of this surplus will be trade in services and because much of the decline in employment in goods production has been, and will be, due to faster productivity growth in goods than in services.
