Article Abstract:
A study examined the optimal environmental investment decision of a firm faced with an environmental regulation schedule that associates maximum production levels and operating costs to the level of its environmental investment. A stochastic output price was used to generate a nontrivial investment schedule for a firm aiming to maximize its economic value in the context of this regulation. A model that ascertains the time when it is optimum to make investments in environmental technologies and considers the basic parameters affecting this decision was developed. The analysis revealed that firms need a significantly high level of output price before making investments in environmental technologies since they optimally would refuse to make substantial irreversible investment that could ultimately be unprofitable if prices fell.

Article Abstract:
It is shown that power series expansions can frequently be employed to gain analytic expressions for the value of a company's investment opportunities. This research indicates how these procedures are applied if a company's investment opportunities have net cash flows which are produced by the Cox, Ingersoll and Ross 'square root process.'
