Understanding the joint dynamics of internat. prices and quantities remains a central issue in internat. bus. cycles. Internat. relative prices appreciate when domestic consumption and output increase more than their foreign counterparts. In addition, both trade flows and trade prices display sizable volatility. This paper incorporates Hicks-neutral and investment-specific TS into a standard two-country general equilibrium model with variable capacity utilization and weak wealth effects on labor supply. Investment-specific TS introduce a source of fluctuations in absorption similar to taste shocks, thus reconciling theory and data. Also presents implications for the transmission mechanism of TS across countries. Illus. This is a print on demand pub.
