Business Cycle Asymmetry Via Occasionally Binding International Borrowing Constraints

This paper illustrates how occasionally binding credit constraints can be quantitatively important to delivering business-cycle asymmetries. An empirical exercise suggests that countries display some business-cycles asymmetries, and an open-economy real business-cycle model is assessed where an international borrowing constraint binds occasionally. In the model, downward movements with a slack constraint are sharper and quicker than upward movements with a binding constraint, and this can deliver asymmetry over the business cycle. The model is calibrated to Canadian data and suggests that a necessary ingredient for asymmetry is a high initial level of foreign debt
