A General Equilibrium Model with Real Exchange Rate [WP]

Abstract

I first write a partial equilibrium model “á la Rogoff” where there are relative prices of non-tradable goods in terms of prices of tradables goods. I find that the behaviour of the real exchange rate shows structural breaks in the short term. Secondly, I explain that any change in the real exchange rate is transitory in the long run. I obtain a general equilibrium model after I add a utility function to the partial-equilibrium model. In the general equilibrium model, an increase occurring in consumption of tradables is going to keep the RER constant over the time
