ABSTRACT

This study is a refinement and an extension of an earlier study by McCulloch of tax effects in the regression equation for term structure estimation. This study includes tests for tax effects and heteroskedasticity, a reconsideration of the need for an instrumental variable, and a search for the capital gains tax rate in addition to the ordinary-income tax rate. There are two major findings: (1) statistically significant tax-induced bias in the non-tax-adjusted equation and (2) evidence that the capital gains tax is misspecified in the tax-adjusted equation.
