Inflation, depreciation and optimal production

Depreciation is an economic outlay, though not a cash outflow. It is recognized as an outlay for tax purposes. This paper deals only with the tax effect of the depreciation method, emphasizing the impact of inflation on both the optimal depreciation method and optimal combination of production factors chosen by firms. In the U.S. and other countries accelerated forms of depreciation were adopted. These methods are analyzed and an optimal one is proposed.
