- WORKING PAPER SERIES - No. 761External imbalances and the US current account: how supply-side changes affect an exchange rate adjustmentDetails
- The influential work of Obstfeld and Rogoff argues that a closing-up of the US current account deficit involves a large exchange rate adjustment. However, the Obstfeld-Rogoff model works exclusively via demand-side channels and abstracts from possible supply-side changes. We extend the framework to allow for endogenous supply-side changes and show that this fundamentally alters the mechanism of the adjustment process. Allowing for such an extension attenuates quite significantly the implied exchange rate adjustment. The paper also provides some empirical evidence of variations in the supply-side structure and correlations with the exchange rate and the current account. The policy implications are that measures to foster a supply-side reaction would facilitate the external adjustment by alleviating an exclusive reliance on demand and exchange rate changes, with the latter being potentially destabilising for the global financial system.

- This paper studies the bank-sovereign link in a dynamic stochastic general equilibrium set-up with strategic default on public debt. Heterogeneous banks give rise to an interbank market where government bonds are used as collateral. A default penalty arises from a breakdown of interbank intermediation that induces a credit crunch. Government borrowing under limited commitment is costly ex ante as bank funding conditions tighten when the quality of collateral drops. This lowers the penalty from an interbank freeze and feeds back into default risk. The arising amplification mechanism propagates aggregate shocks to the macro-economy. The model is calibrated using Spanish data and is capable of reproducing key business cycle statistics alongside stylized facts during the European sovereign debt crisis.
