Will people report both posttraumatic growth and depreciation following a highly stressful event? Using the Posttraumatic Growth Inventory as the measure of growth, two studies compared responses to equivalent items designed to assess depreciation. Both types of change were reported, but growth was reported at much higher levels, and there was no correlation between growth and depreciation. Sma...

This paper studies how the difference between technical depreciation and tax depreciation affects the firm’s optimal investment strategy. The objective is maximization of shareholder value. When tax depreciation differs from technical depreciation, an additional investment not only generates value due to the fact that the firm can produce more, but also due to the fact that an additional deferr...

Firms can use capital that they either purchase or lease, but these alternatives are treated differently for tax purposes. This paper derives the demand for leased capital as a function of tax parameters, and uses the model to estimate the responsiveness of leasing to the introduction of bonus depreciation in 2002, finding strong evidence that depreciation allowances influence leasing patterns....

R&D depreciation rates are critical to calculating the rates of return to R&D investments and capital service costs, which are important for capitalizing R&D investments in the national income accounts and harmonizing BEA statistics with those of the productivity program of BLS. Although important, measuring R&D depreciation rates is extremely difficult because both the price and output of R&D ...

We consider a discrete-time two-sector Cobb-Douglas economy with positive sector specific external effects and partial depreciation of capital. We show that local indeterminacy of steady states and cycles can easily arise with constant social returns to scale, and very small market imperfections. However these properties of equilibrium paths become less likely in the case of partial depreciatio...

Light Emitting Diode (LED) luminaires and lamps are energy-saving and environmental friendly alternatives to traditional lighting products. However, current luminous flux depreciation test at luminaire and lamp level requires a minimum of 6000 h testing, which is even longer than the product development cycle time. This paper develops an accelerated test method for luminous flux depreciation to...

An energy storage system is critical for the safe and stable operation of a microgrid (MG) and has a promising prospect in future power system. Economical and safe operation of storage system is of great significance to MGs. This paper presents an improved management strategy for lithium battery storage by establishing a battery depreciation cost model and employing a practical charging/dischar...

The Review of Business Taxation chaired by Mr John Ralph has suggested sweeping changes to business taxation in Australia. In particular it has been proposed that accelerated depreciation provisions be removed to finance a reduction in the company tax rate. If some degree of accelerated depreciation is to be retained, it is suggested that this should involve a uniform loading on depreciation ra...
