Towards a Reconciliation of the Empirical Evidence on the Monetary Approach to Exchange Rate Determination.

The monetary approach to exchange rate determination has served as a theoretical workhorse in open economy macroeconomics, yet empirical evidence concerning its validity is mixed: tests based on structural forms of the model are typically negative, while cross-equation restrictions tests based on nonstructural representations are typically favorable. The authors s eek a reconciliation of these results by investigating the small-sample performance of cross-equation restrictions tests. Their investigatio n indicates that the tests have surprisingly low power in detecting nontrivial departures from the model, thus the authors conclude that something is amiss with standard versions of the monetary approach t o exchange rate determination.
