Abstract
In his fundamental works and Douglas Vickers integrates the production, investment and financing decisions of the firm into a useful and illuminating model. He deals with uncertainty using risk-adjusted capitalization and interest rates, assumes constant business risk and treats financial risk as a function of leverage. This paper extends Vickers' analysis by allowing business risk to depend on production and investment decisions. In particular, it derives a criterion for investment decisions under general uncertainty and market organization conditions when business risk is subject to control.
