After presenting the structural models of exchange-rate determination, the authors show that their out-of-sample predictive performance of the lira/$ exchange rate is inferior to that of the random walk model. Only by moving away from these single-equation, semireduced form models toward...

We first give a brief presentation of the existing single-equation structural models of exchange-rate determination and a survey of how the exchange rate is modeled in the main economy-wide macroeconometric models. We then show, with respect to the lira/$ exchange rate, that the out-of-sample...
