This paper shows that the degree of competition affects the current account response to nominal shocks. The mechanism hinges on the relationship between the mark-up and the degree of real rigidity of prices. In a model with intermediate goods, the degree of real rigidity increases in the markup. A weaker response of prices to nominal shocks strengthens the "expenditure switchingʺ effect of the devaluation to the benefit of the current account. We first analyse the relationship between the mark-up and the real rigidity in a simple closed economy model. We then show numerically how the mark-up can affect the response of the current account to monetary shocks.
