The main alternative to a weak currency as a means of helping weak economies is a system of transfer payments and subsidies. Donald MacDougall showed that the cost of intra-union subsidies (between nations, or between regions) necessary to offset the removal of the exchange rate and interest rate flexibility would require a federal expenditure of at least 7.5–10 percent of GDP, equal to 14 times the level of intra-union transfers in 2001 (calculated on the midpoint of 8.75 percent).
