     The Effects of Price Volatility and

                           I. INTRODUCTION

  The taxation of investments in capital assets poses some of the most
difficult problems under an income tax because of the deferral of re-
turns and the volatility of prices. Recent measures address the prob-
lem of tax deferral when investments pay deferred returns by
imputing income based on the expected return when the investment is
made. The original issue discount (OID) rules have evolved in this
direction' and recent regulations on notional principal contracts2 and
proposed regulations on contingent interest3 include fairly sophisti-
cated rules that use the expected return method. Important recent
scholarship has sought to extend and to refine this method.4 Other

Something akin to expected return taxation would occur if firms that undertook construc-
tion projects were required to impute income on capital devoted to the construction based
on its expected return. See Thomas L. Evans, The Taxation of Multi-Period Projects: An
Analysis of Comleting Models, 69 Tex. L. Rev. 1109, 1143-44 (1991). One issue in the
design of an expected return rule is whether income should be imputed in a way that
accounts for the slope in the yield curve rather than on a constant yield to maturity
method. See generally Joseph Bankman & William A. Klein, Accurate Taxation of Long-
Term Debt: Taking Into Account the Term Structure of Interest, 44 Tax L Rev. 335 (1989)
(arguing that the difficulty of determining yield curves of long-term debt ex ante means
that income can be measured accurately only by ex post valuations, as under a mark-to-
market rule); see also Theodore S. Sims, Long-Term Debt, the Term Structure of Interest
and the Case for Accrual Taxation, 47 Tax L. Rev. 313 (1992) (arguing that although the
method for accruing interest can be adjusted to account for the usual upward slope in yield
curves, it is not worth the effort because the effect of not accounting for sloping yield
