Abstract:
Two country applications of equilibrium business cycle methodology have succeeded in matching some key features of international fluctuations. However, discrepancies between theory and data remain. This paper identifies a new anomaly related to a basic property of typical models: the prediction of countercyclical net exports is fundamentally related to (counterfactual) implication for negative cross-country investment correlations. Although the introduction of investment adjustment costs can reverse this anomaly, it has the side-effect of inducing the wrong cyclical behavior for net exports. Possible resolutions to this puzzle are considered, including asset market restrictions and the role of the substitution elasticities.
