In a recent paper Mercenier and Sekkat (1988) conclude that the Bank of Canada has followed a policy of exchange rate targeting using the money supply. We re-examine their results using a different estimation approach and with different assumptions about the forcing process of the exogenous variables.

Since the early 1980s, models based on economic fundamentals have been poor at explaining the movements in the exchange rate (Messe 1990). In response to this problem, Frankel and Froot (1988) developed a model that uses two approaches to forecast the exchange rate: the fundamentalist approach, which bases the forecast on economic fundamentals, and the chartist approach, which bases the forecast on the past behaviour of the exchange rate.

For the five overseas countries considered in this study (Germany, France, Italy, the United Kingdom and Japan), data on real GDP are released on a quarterly basis at least two months after the end-of-quarter.

In this paper known results about the equivalence of state space and autoregressive moving-average models with exogenous inputs (ARMAX) (including vector auto-regressive or VAR models) are reviewed. While most of these results are not new, no single reference appears to bring together several important related points.

This paper replicates and extends the econometric work of two previous studies of output-inflation dynamics in Canada -- Fortin (1991) and Cozier and Wilkinson (1991) -- in an attempt to reconcile their divergent conclusions.
