Optimum currency area theory
Optimum currency area theory adopts the presumption that a currency area confers a benefit upon its members by eliminating exchange rate risks and reducing transactions costs. Its analysis concerns the extent to which that benefit may be offset by the risk of an additional cost when there is a recession. Such an additional cost arises when there is a difference between the monetary policy response to the recession that is appropriate for a member country, and that which is appropriate for the currency area as a whole. When that happens, some member countries may suffer unemployment and other economic costs that they could have avoided if they had retained control over their national monetary policies. It is liable to happen when the currency area experiences an asymmetric shock which affects the economies of some member countries more than others.
The term "optimum currency area" is believed to have been coined by the eminent economist Robert Mundell to denote the theoretical concept of an area in which there are no such offsetting costs. Mundel's analysis demonstrated that a sufficient condition for its definition would be would be either a frictionless migration of labour, or a frictionless adaptation of labour and product costs, in response to a change in demand[1]. Developing Mundell's analysis, Robert McKinnon has argued that the more open the economies of a currency area, the lower will be the costs arising from price rigidities[2], and Peter Kenen has argued that the greater the similarity of the economies of a currency area the smaller will be the magnitude asymmetric shocks, and that the more diversified is an individual economy the lower will be its vulnerability to such shocks [3].
OCA theory and the Eurozone
The eurozone does not meet Mundell's labour migration or cost flexibility requirements. Labour mobility is low[4] and there is limited wage and price flexibility[5][6]. There have also been large differences in economic and financial structures[7]. and the initial expectation that mewmbership would reduce them has not been realised[8].
