Cointegrated TFP processes and international business cycles
A puzzle in international macroeconomics is that observed real exchange rates are highly volatile. Standard international real business cycle (IRBC) models cannot reproduce this fact. We show that total factor productivity processes for the United States and the rest of the world are characterized by a vector error correction model (VECM) and that adding cointegrated technology shocks to the standard IRBC model helps explaining the observed high real exchange rate volatility. Also, we show that the observed increase of the real exchange rate volatility with respect to output in the past ...

Net foreign assets and imperfect pass-through: the consumption real exchange rate anomaly
An unresolved issue in international macroeconomics is the apparent lack of risk-sharing across countries, which contradicts the prediction of models based on the assumption of complete markets. We assess the importance of financial frictions in this issue by constructing an incomplete market model with stationary net foreign assets (NFA) and imperfect pass-through (IPT). In this paper, there is a cost of bond holdings that allows us to incorporate the dynamics of NFA into the risk-sharing condition. On theoretical grounds, our results suggest that the dynamics of NFA may account for the lack ...
