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 TFP processes for the U.S. and the "rest of the world," is characterized by a vector error correction (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 last 20 year can be explained by changes in the parameter of the VECM.

Potential Output is a key factor for debt sustaintability analysis and for developing strategies for growth, but unfortunately it is an unobservable variable. Using three methodologies (production function, switching, and state-space), this paper computes potential output for CAPDR countries using annual data. Main findings are: i) CAPDR potential growth is about 4.4 percent while output gap volatility is about 1.9 percent; ii) The highest-potential growth country is Panama (6.5 percent) while the lowest-growth country is El Salvador (2.6 percent); iii) CAPDR business cycle is about eigth years.
