The Indexation of Interest, Depreciation, and Capital Gains: A Model of Investment Incentives

Working Paper: NBER ID: w1655

Authors: Don Fullerton

Abstract: Despite much recent interest in a consumption tax, the Treasury Department's November 1984 tax plan proposes to adopt carefully coordinated features of a more comprehensive income tax, including the indexation of interest, depreciation, and capital gains.The May 1985 White House proposal would retain some of these indexing provisions.This paper looks at the incentives under alternative tax regimes to make marginal investments in the corporate sector, noncorporate sector, and in owner-occupied housing. It finds that the current system is characterized by effective tax rates that increase with inflation for some assets and decrease with inflation for other assets. Overall rates fall with inflation, and the corporate tax is completely offset by credits, allowances, and deductions. Under the Treasury or White House plans, the corporate tax re-emerges, effective tax rates are considerably more uniform, and the interference of inflation is virtually eliminated.
