F32 Current Account Adjustment; Short-term Capital Movements

In a two-country DSGE model, the effects of foreign demand shocks on the home country are greatly amplified if the home economy is constrained by the zero lower bound for policy interest rates. This result applies even to countries that are relatively closed to trade such as the United States. Departing from many of the existing closed-economy models, the duration of the liquidity trap is determined endogenously. Adverse foreign shocks can extend the duration of the trap, implying more contractionary effects for the home country; conversely, large positive shocks can prompt an early exit, implying effects that are closer to those when the zero bound constraint is not binding.

Understanding the joint dynamics of international prices and quantities remains a central issue in international business cycles. International 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 technology shocks into a standard two-country general equilibrium model with variable capacity utilization and weak wealth effects on labor supply. Investment-specific technology shocks introduce a source of fluctuations in absorption similar to taste shocks, thus reconciling theory and data. The paper also presents implications for the transmission mechanism of technology shocks across countries and for the Barro and King (1984) critique of investment shocks.

We study the cross-section correlations of net, total, and disaggregated capital flows for the major source and recipient European Union countries. We seek evidence of changes in these correlations since the introduction of the euro to understand whether the European Union can be considered a unique entity with regard to its international capital flows. We make use of Ng’s (2006) “uniform spacing” methodology to rank cross-section correlations and shed light on potential common factors driving international capital flows. We find that a common factor structure is suitable for equity flows disaggregated by sign but not for net and total flows. We only find mixed evidence that correlations between types of flows have changed since the introduction of the euro.
