Abstract
We propose a fundamentals-based econometric model for the weekly changes in the
euro-dollar rate with the distinctive feature of mixing economic variables quoted at different
frequencies. The model obtains good in-sample fit and, more importantly, encouraging outof-sample forecasting results at horizons ranging from one week to one month. Specifically,
we obtain statistically significant improvements upon the hard-to-beat random walk model
using traditional statistical measures of forecasting error at all horizons. Moreover, our model
improves greatly when we use the direction-of-change metric, which has more economic
relevance than other loss measures. With this measure, our model performs much better
at all forecasting horizons than a naive model that predicts the exchange rate has an equal
chance to go up or down, with statistically significant improvements.
Keywords: euro-dollar rate, exchange rate forecasting, State-space model, mixed
frequencies.
JEL classification: F31, F37, C01, C22.
Resumen
Se propone un modelo econométrico basado en fundamentales para el cambio semanal del
tipo de cambio del euro frente al dólar con la característica diferencial de mezclar variables
con diferentes frecuencias. El modelo obtiene buenas predicciones en la muestra, y, lo
que es más importante, mejoras en predicción fuera de la muestra a horizontes entre una
semana y un mes. Específicamente, obtenemos mejoras estadísticamente significativas
frente al difícil de batir paseo aleatorio, usando las medidas tradicionales basadas en error
de predicción cuadrático medio a todos los horizontes. Las ganancias son mayores cuando
utilizamos la métrica basada en la dirección del cambio, que tiene más sentido económico en
un modelo como este. Con esta medida, nuestro modelo predice los movimientos alcistas
y bajistas del tipo de cambio mucho mejor que un modelo basado en igual probabilidad de
bajadas y subidas.
Palabras claves: Tipo de cambio euro-dólar, predicción de tipos de cambio, modelo de
ecuación de estados y frecuencias mixtas.
