This paper provides estimates of the extent to which corporate and personal income taxes are capitalized in bond prices. The methodology yields estimates of the degree of tax capitalization, rather than an implied tax rate. This makes it straightforward to identify the marginal investor and test for changes in tax capitalization. The empirical approach also makes it unnecessary to jointly estimate the degree of tax capitalization and the entire yield curve. Corporate taxes are found to have been fully capitalized in pre-tax Government of Canada bond yields during the period 1986–1993. Since 1994, taxes have not been capitalized in yields. These results are consistent with the existence of a marginal investor, but the identity of the marginal investor changed from a financial sector firm to a non-taxed entity in the early 1990s.

Additional empirical evidence is provided concerning the impact of government financing decisions on monetary expansion in the United States for the post-World War II period. The budget position of the fiscal authority and the rate of money growth set by the Fed are specified as endogenous variables within a system of equations. The empirical analysis generates evidence of a policy shift in the 1980s, with budget deficits exerting no independent influence on high-powered money growth prior to 1981 while, after 1981, such a linkage is found to exist.
