A simulation model of R&D budgeting

A simple simulation model is developed that allows the testing of alternative heuristic rules for R&D budgeting. Sales-dependent budgeting, all-you-can-afford budgeting, and budgeting tied to a target rate of product innovativeness are studied. It can be shown that the choice of the budgeting rules as well as their parameters interact with market diffusion of new products as well as with R&D returns to scale. Thus, budgeting to achieve certain growth or profit objectives has to keep these interactions in mind.
