The paper shows first that real exchange rate appreciation typically reduces, but may increase, the output costs of disinflation. The direct favorable effects of cheaper imports on consumer prices, on the prices of imported inputs, on wage demands, and on the demand for money may be outweighed by the unemployment caused by the trade deficit. Second, the effects of wage indexation on the costs of disinflation are reexamined. Ex ante indexation speeds up disinflation. Ex post indexation, the type observed in practice, automatically increases the real wage at the start of a disinflation and may therefore increase the sacrifice ratio.

This paper studies trade theory for the case of a continuum of goods, two factors, two countries, and Cobb-Douglas demand functions. If factor endowments are similar, factor price equalization obtains and geographic patterns of production are indeterminate; nonetheless the effects of changes in factor endowments on prices and welfare in each country are well defined. Factor price equalization does not obtain if factor endowments are far apart, and the geographic pattern of specialization is then determinate. The effects of changes in endowments on the range of goods produced in each country and on prices of goods and factors are analyzed for this case, and the elasticity of substitution in production is shown to play an important role in determining comparative static outcomes.
