Traditional fire programs are composed of several major components including: suppression and initial attack, prevention, fuel treatments. There are three key reasons that these components should be managed under a single program and they each are related to other components in the economic structure of fire management. These include the treatment of joint costs, the complementary or substitution effects in component productivity and the management of the components under a common budget. Considering the interactions between the components suggests an expansion of the economic theory of fire management to be more comprehensive. The probabilistic production function used here allows these program components to be unified into a common expression of performance and facilitates a simultaneous consideration across components. This theoretic structure provides a natural evolution of the generalized theory of fire economics that began with Headly and Sparhawk.
