Underemployment and capital irreversivility in a unionized overlaping generations economy

In a unionized OLG model, it is shown that steady-state underutilization of labour and equipment can be due to the combination of the two following elements: (i) Irreversibility of capital, technology and skill decisions, (ii) Firm specific shocks on productivity. The presence of unions is neither sufficient nor necessary for having unemployment. The result of Devereux and Lockwood (1991) that union power affect positively the capital stock in general equilibrium does not always hold under capital irreversibility

Irreversible Investment, Incremental Capital Accumulation, and Price Uncertainty

We consider optimal incremental capital accumulation in the presence of investment irreversibility and general price uncertainty. We present a set of general conditions under which the optimal capital accumulation path can be explicitly characterized in terms of an ordinary threshold rule stating that investment is optimal whenever the underlying price exceeds a capital-dependent threshold. We also present a set of general conditions under which increased price volatility expands the region where investment is suboptimal and decreases both the expected cumulative present value of the marginal revenue product of capital and the value of the future expansion options.Price uncertainty, irreversible investment, incremental capital accumulation.

UNDERSTANDING INVESTMENT IRREVERSIBILITY IN GENERAL EQUILIBRIUM

This paper advances a tractable model designed to understand investment irreversibility in general equilibrium. The tractability of the model allows analytical results which explain the contrast, emphasized in the extant literature (e.g., Coleman [1997]), between the consequences of irreversibility for individual firms and the consequences of irreversibility for the whole economy. In general equilibrium, irreversibility affects both the wealth of consumers and the return on assets. In the model explored, as long as the inter-temporal elasticity of substitution is realistically low (less than one), investment irreversibility not only prevents capital destruction, but it also induces capital creation. Furthermore, under certain conditions, irreversibility raises the risk premium by increasing the variability of both consumption and the market portfolio.Irreversible Investment, Stochastic Growth, Asset Pricing

Optimal monopoly investment and capacity utilization under random demand

Unique value-maximizing programs of irreversible capacity investment and capacity utilization are described and shown to exist under general conditions for monopolist exhibiting capital adjustment costs and serving random consumer demand for a nondurable good over an infinite horizon. Stationary properties of these programs are then fully characterized under the assumption of serially independent demand disturbances. Optimal monopoly behavior in this case includes acquisition of a constant and positive level of capacity, the maintenance of a positive expected value of excess capacity in each period, and an asymmetrical response of price to unanticipated fluctuations in consumer demand. Under a general form of Markovian demand, the effect of uncertainty on irreversible capacity investment is also described in terms of the discounted flow of expected revenue accruing to the marginal unit of existing capacity and the option value of deferring the acquisition of additional capital. The option value of deferring such acquisition, created by the irreversibility of capacity investment, is characterized directly in terms of the value function of the firm, and is then shown to be zero in a stationary equilibrium with serially independent demand disturbances. The response of investment to increase demand uncertainty depends, as a result, directly on the properties of the marginal revenue product of capital. A non-negative response of optimal capacity to increased uncertainty in market demand is demonstrated for a general class of aggregate consumer preferences.Industrial capacity

The Determinants of Private Investment in Benin: A Panel Data Analysis

Investment is one of the mainsprings of economic growth. In order to analyse the factors explaining the weakness of investment by private firms in Benin, this paper used a capital demand function. This function was estimated using data from a panel of 123 firms in Benin and covering the 19972003 period. The findings showed that demand uncertainty and, more importantly, the fluctuations in the imports of manufactured goods from Nigeria have a negative effect on investment by private firms in Benin. The investment behaviour of these firms strongly hinges on the cost of capital utilization: When this cost is high, it weighs negatively on the purchase and installation of new production infrastructure. The magnitude of the effect of this cost of capital utilization and of the demand uncertainty which investment firms face depends on the nature of their activities.

Increasing optimism and demand uncertainty

By allowing the initial prior over market size to be a mixture of distributions, this paper extends the model of irreversible investment under uncertainty proposed by Rob (1991). We find that capacity expansion fuels investors' optimism. It is shown in the paper that the crash is always preceded by a boom when the initial prior is a mixture of exponential distributions.Learning Investment Uncertainty

The Impact of Tax Uncertainty on Irreversible Investment

Tax legislation, fiscal authorities, and tax courts create tax uncertainty by frequent tax reforms and various different interpretations of the tax law. Moreover, investors generate model-specific tax uncertainty by using simplified models that anticipate the actual tax base incorrectly. I analyze the effects of stochastic taxation on investment behavior in a real options model. The investor holds an option to invest in an irreversible project with stochastic cash flows. To cover the effects of both tax base and tax rate uncertainty, the investment’s tax payment is modelled as a stochastic process. Increased tax uncertainty has an ambiguous impact on investment timing. The view that tax uncertainty depresses real investment is rejected. A higher expected tax payment delays investment. A higher tax rate on interest income affects investment timing ambiguously.tax uncertainty, capital budgeting, real options, investment incentives
