    Operational asset replacement strategy : a real options approach

    Get PDF
    This article analyses the problem of replacement by investigating the optimal moment of investment replacement in a given tax environment with a given depreciation policy. An operation and maintenance cost minimization model, based on the definition of equivalent annual cost, is applied to a real options paradigm. The developed methodology allows for an innovative evaluation of the flexibility of replacement process analysis. A new two- factor evaluation function is introduced to quantify decisions of asset replacement under a unique cycle environment. This study improves upon previous findings in the literature as it accounts for autonomous salvage value processes. Based on partial differential equations, this model achieves a general analytical solution and particular numerical solution. The results differ significantly from those observed in one-factor models by showing evidence of over-evaluation in optimal levels of replacement, and by confirming suspicions that different types of uncertainties produce non-monotonous effects on the optimal replacement level. The scientific contribution of this study lies in new and stronger approaches to equivalent annual cost literature, supplying an algorithm for operation and maintenance cost minimization that is conditioned by autonomous salvage value. This study also contributes to the real options literature by developing of a two-factor model with Brownian processes applied to asset replacement.info:eu-repo/semantics/publishedVersio

    OPTIMAL REPLACEMENT INTERVAL AND DEPRECIATION METHOD FOR A GRAIN COMBINE

    A stochastic dynamic programming model is developed to determine optimal replacement intervals and depreciation schedules for a combine on a cash grain farm in north central Montana, where the optimal decision is based on the stochastic nature of winter wheat prices. Empirical results indicate that the decision varies widely depending on the states describing the conditions facing the farm firm. Under normal profitable conditions and ERTA81 tax legislation, suggested replacement is after five years of service, the new asset being depreciated under the accelerated cost recovery system and the investment credit option. Changes to the tax law would tend to smooth out and increase this replacement interval.Agricultural Finance, Farm Management,

    TAX REFORM AND BEEF COW REPLACEMENT STRATEGY

    This paper models optimal beef cow replacement strategy in a stochastic environment under U.S. income tax rules effective before and after the Tax Reform Act of 1986. Under each tax regime, the producer's buy versus raise decision and optimal culling age choice are analyzed. Per-cow profit levels are also calculated. Results of the numerical analysis indicate that tax law changes, particularly the loss of the capital gains exclusion and restrictions on preproduction expensing, will have significant effects on both optimal decisions and profitability of beef cow operations. When provisions of the Tax Reform Act of 1986 are fully effective in 1988, the optimum age for culling beef cow will increase, as will the after-tax costs of beef cow operations.Agricultural Finance, Livestock Production/Industries, Public Economics,

    Consumption and Investment

    This paper presents an overview of current models of consumption and investment behavior. First, the stochastic implications of the permanent income model and empirical tests of these implications are discussed. Then the simple theoretical model is extended to include expenditure on consumer durables. In addition, the implications of liquidity constraints and the unpredictability of the rate of return on wealth are discussed. The overview of consumption behavior closes with a critical discussion of the Ricardia Equivalence Theorem. Investment behavior is analyzed using a dynamic optimization model of a firm facing costs of adjustment. This framework integrates the accelerator model, the neoclassical model and the q theory. The model is then used to analyze the interaction of corporate taxes, inflation and investment and also to analyze the effects of uncertainty on investment. The overview of investment concludes with a discussion of inventory investment.

    FARM MACHINERY INVESTMENT AND THE TAX REFORM ACT OF 1986

    The Tax Reform Act of 1986 significantly changed incentives for investing. This analysis specifically examines how changes in marginal tax rates, depreciation schedules, and the investment tax credit altered the cost of capital and net investment in agriculture. A stochastic coefficients econometric methodology is used to estimate an investment function which is then used to simulate the effects of tax reform. Estimates indicated that relative to prior law, the Tax Reform Act will reduce the capital stock of farm machinery and equipment by nearly $4 billion.Agricultural Finance, Farm Management,

    Investment, Tobin's Q, and Multiple Capital Inputs

    Get PDF
    Despite their solid theoretical basis, models of business investment based on Tobin's Q theory have recorded a generally disappointing empirical performance. This paper examines one possible source of misspecification. When the firm's technology is expanded to include two or more capital inputs, the investment equation following from maximizing behavior includes Q as well as a series of additional explanatory variables. The importance of these omitted variables is assessed, and the econometric evidence is mixed, as the Multi-Capital Q model clearly dominates the Conventional specification but empirical problems remain. In addition, the implications of the parameter estimates from the Conventional and Multi-Capital models for tax policy are noted.

    A FURTHER LOOK AT THE EFFECT OF FEDERAL TAX LAWS ON OPTIMAL MACHINERY REPLACEMENT

    Self-employment taxes, "effective" marginal tax rates, and discounting schemes which allow for alternative purchase and disposal dates of machinery are incorporated into the traditional optimal replacement interval model. Empirical results indicate that these alterations decrease the optimal replacement intervals by up to three years from those obtained with traditional modeling assumptions. Inclusion of self-employment taxes decreases both the penalty attached to early replacement and the net present value (cost) of tractor ownership.Agricultural and Food Policy,
