The design of buildings is a multi-criterion optimization problem, there always being a tradeoff to be made between capital expenditure, operating cost, and occupant thermal comfort. This paper investigates the application of a multi-objective genetic algorithm (MOGA) search method in the identification of the optimum payoff characteristic between the elements of the building design problem. Re...

With increasing expenses for future HPC centers, the need to look at their productivity, defined as amount of science per total cost of ownership (TCO), grows. This includes development costs which arise from development effort spent to parallelize, tune or port an application to a certain architecture. Development effort estimation is popular in software engineering, but cannot be applied dire...

Levy and Arditti (1973) introduced depreciable assets into the Modigliani and Miller (1958) model, and analyzed the implications for the cost of capital. Assuming that the firm reinvests indefinitely to maintain a constant expected cash flow, they found that depreciation increases the cost of capital before and after tax. Most of their assumptions are maintained. However, commitment to perpetua...

This paper recognizes two main factors that cause the capital requirement to affect the weighted average cost of capital and hence the investment behavior ofbanks: underpriced debt resulting from the deposit insurance and information asymmetry between managers and the stock market. For a bank enjoying a low cost of debt (deposits), an increased proportion of equity financing raises the weighted...

Intangible capital has arguably become an important component of corporate value. However, it is still an open question whether uncertainty associated with investment in intangible capital is higher or lower than physical capital. We estimate the value of intangible capital in a dynamic stochastic general equilibrium model that features capital adjustment costs, investment-speci c technological...

We propose a cross-sectional time-series model to assess the impact of market liberalizations in emerging equity markets on the cost of capital, volatility, beta, and correlation with world market returns. Liberalizations are defined by regulatory changes, the introduction of depositary receipts and country funds, and structural breaks in equity capital flows to the emerging markets. We control...

The shadow return on capital in 75 small municipal water systems is estimated using a gamma frontier variable cost function. The estimated Social Cost of capital exceeds the shadow return by an average ratio of 4.37:1, with a median capital stock inefficiency of $70, 500 per year per system owing to overinvestment in public water supply capital. In addition, actual production costs exceed minim...

Taking advantage of the opportunities created by the price adjusted performance improvement in IT depends in part on the ability of IT capital to substitute for other inputs in production. Studies in the IS literature as well as most economics training that examine substitution of IT capital for other inputs use the Allen elasticity of substitution (AES). We present a less-well-known measure fo...
