Empirical Exchange Rate Models of the Nineties: Are Any Fit to Survive?

ABSTRACT: Previous assessments of forecasting performance of exchange rate models have focused
upon a narrow set of models typically of the 1970’s vintage. The canonical papers in this
literature are by Meese and Rogoff (1983, 1988), who examined monetary and portfolio balance
models. Succeeding works by Mark (1995) and Chinn and Meese (1995) focused on similar
models. In this paper we re-assess exchange rate prediction using a wider set of models that have
been proposed in the last decade: interest rate parity, productivity based models, and a composite
specification incorporating the real interest differential, portfolio balance and nontradables price
channels. The performance of these models is compared against two reference specifications –
the purchasing power parity and the Dornbusch-Frankel sticky price monetary model. The
models are estimated in error correction and first-difference specifications. Rather than
estimating the cointegrating vector over the entire sample and treating it as part of the ex ante
information set as is commonly done in the literature, we also update the cointegrating vector,
thereby generating true ex ante forecasts. We examine model performance at various forecast
horizons (1 quarter, 4 quarters, 20 quarters) using differing metrics (mean squared error,
direction of change), as well as the “consistency” test of Cheung and Chinn (1998). No model
consistently outperforms a random walk, by a mean squared error measure; however, along a
direction-of-change dimension, certain structural models do outperform a random walk with
statistical significance. Moreover, one finds that these forecasts are cointegrated with the actual
values of exchange rates, although in a large number of cases, the elasticity of the forecasts with
respect to the actual values is different from unity. Overall, model/specification/currency
combinations that work well in one period will not necessarily work well in another period.
