Behavioural equilibrium exchange rate and total misalignment: evidence from the euro exchange rate

In the present paper we attempt to investigate whether the nominal exchange rate of the euro against the currencies of the four major trading partners of the eurozone, namely China, Japan, the UK and the USA, converges or not to its equilibrium level. Applying recent unit root and system cointegration techniques in the presence of structural shifts in the data, our results indicate that there exist an equilibrium relationship between each of the euro/yuan, euro/yen, euro/UK pound and euro/US dollar nominal exchange rates and the fundamentals defined by the monetary model. Following these results, our modified Behavioural Equilibrium Exchange Rate model suggests that at the end of the estimated period, the euro/Chinese yuan and the euro/UK pound nominal exchange rates follow an equilibrium process. Our empirical results also imply that the single European currency is considered as overvalued against the US dollar, while it is considered as undervalued against the Japanese currency.
