THE MEASUREMENT OF A FIRM'S COST OF CAPITAL

The relevance of a firm's cost of capital in its investment decisions is widely recognised. The concept and associated issues have been and are likely to be increasingly important in the regulatory activities of government and semi-government bodies, e.g. prices regulation, profit regulation for semi-government enterprises, antitrust and takeover regulation. This paper outlines the principles involved in estimating a firm's before-tax and after-tax cost of capital. The paper also suggests practical approaches that may be taken when difficulties arise in estimating parameters to the problem.     

A NOTE ON THE MARGINAL COST OF DEBT CAPITAL

The firms marginal cost of debt capital was interpreted in this author's previous publications as the "full marginal cost of relaxing the money capital availability constraint' when the incremental money capital employed takes the form of debt capital. Account is thereby taken of the effects on financing costs of the increased risk exposure that debt financing implies for both debt and equity holders. The present paper clarifies a misconception in a recently published paper by Draper and Findlay, and exhibits the linkage between concepts relevant to the firm's fmancing decision and the general marginal analysis.     

THE COST OF CAPITAL OF A COMPANY UNDER AN IMPUTATION TAX SYSTEM

One of the issues arising out of the introduction of an imputation tax for companies in Australia is the effect it is likely to have on the definition and measurement of a company's cost of capital. Insofar as there is a difference between the value of a dollar of franked relative to unfranked dividends, conventional definitions for the cost of capital are inappropriate and new definitions are required. This has implications for the measurement of a company's cost of capital and for the definition of net cash flows that are used in conjunction with the cost of capital. This paper sets out these definitions and an approach for measuring the cost of capital. The new definition of the cost of capital replaces the effective company tax rate T with T(l - γ) where γ is the value of personal tax credits. Further, the definition of the risk premium in the capital asset pricing model requires an adjustment for the capitalized value of personal tax credits to maintain consistency between the cost of capital and cash flows which are defined on an after-company tax but before-personal tax basis.     

THE EFFECTS OF BANK CONSOLIDATION ON RISK CAPITAL ALLOCATION AND MARKET LIQUIDITY

We investigate the effects of financial market consolidation on the allocation of risk capital in a financial institution and the implications for market liquidity in dealership markets. An increase in financial market consolidation can increase liquidity in foreign exchange and government securities markets. We assume that financial institutions use risk‐management tools in the allocation of risk capital and that capital is determined at the firm level and allocated among separate business lines or divisions. The ability of market makers to supply liquidity is influenced by their risk‐bearing capacity, which is directly related to the amount of risk capital allocated to this activity.     

THE USER COST AND CAPITAL BUDGETING

This study describes the relationship between the user cost of capital and capital budgeting processes and presents a formula for computing the user cost of an investment, accommodating the existence of taxes, inflation, and a nonconstant level of production. A project acceptability criterion assigning positive net present value when cash operating income exceeds user cost is discussed and applied to several examples. The test is shown to be useful and easy to apply.
