Non-Traded Goods and Real Exchange Rate Volatility in a Two-Country DSGE Model

This paper uses a two-country dynamic stochastic general equilibrium model (DSGE) to study how different characteristics of an economy, such as openness or price stickiness, affect the contribution of the relative price of non-traded goods to real exchange rate fluctuations. The model shows that changes in the relative price between traded and non-traded goods are the main channel through which productivity shocks are transmitted to the real exchange rate. Productivity and monetary shocks also affect the real exchange rate through changes in the international relative price of traded goods. The economy's characteristics have a significant effect on the transmission mechanism and the overall volatility of the real exchange rate in response to both types of shocks
