In this paper we evaluate the predictive power of the three most popular equilibrium exchange rate concepts: Purchasing Power Parity (PPP), Behavioral Equilibrium Exchange Rate (BEER) and the Macroeconomic Balance (MB) approach. We show that there is a clear trade-off between storytelling and forecast accuracy. The PPP model offers little economic insights, but has good predictive power. The BEER framework, which links exchange rates to fundamentals, does not deliver forecasts of better quality than PPP. The MB approach has the most appealing economic interpretation, but performs poorly in forecasting terms. Sensitivity analysis confirms that changing the composition of fundamentals in the BEER model or modifying key underlying assumptions in the MB model does not generally enhance their predictive power.

This box assesses recent empirical analysis claiming that services trade liberalisation could be a remedy for global imbalances. The main finding of the box is that global imbalances – i.e. the magnitude of current account surpluses and deficits across countries – would remain essentially unchanged as a result of services trade liberalisation. Nonetheless (services) trade liberalisation should be expected to raise welfare overall, e.g. by fostering productivity growth.
