This paper studies the implication, in terms of welfare and monetary policy, of unequal degrees of competition across members of a currency area. We look at two ways in which the degree of competition in the market for goods can affect welfare in a currency area. One is through different average...

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....

This paper surveys and motivates the reasons for incorporating explicit long run of supply features into applied estimated macro economic models. It defines some basic stability conditions for such models and illustrates elements of long run considerations with reference to a small (22 equation)...
