This paper investigates tax effects in the Canadian government bond market during the period 1964—1986. Unlike previous studies, we apply both statistical and nonstatistical teststo analyze clientele effects and market equilibria. The results divide the sample into two distinct periods of time, with the end of 1976 marking the division. We find that tax effects are almost nonexistent in the Canadian government bond market before the end of 1976, but are predominant in the post-1976 period. Non-segmented market equilibria cannot be rejected before 1977, but are strongly rejected after 1976. In fact, segmented equilibria with clientele effects in both quantities and prices characterize the entire five year period from 1982 to 1986. These findings are consistent with tax reforms, government deficit financing and interest rate fluctuations in Canada during our sample period.

The goal of this paper is to determine whether the tax-timing option effect documented in the U.S. bond market exists outside the U.S. Examining Canadian tax rules suggests that the tax option effect is simpler and less valuable than in the U.S. This view is supported by simulations in the spirit of Constantinides and Ingersoll (1984) as well as by empirical tests conducted on bond triplets following Jordan and Jordan (1991).
