This paper examines the determinants of innovations and market structure within a simultaneous framework. From a competitive fringe model, quasi-conditional factor demand functions are derived that explain product and process innovations in terms of factor prices and market structure variables such as relative firm size, market size, and the concentration ratio where the latter set of variables result from the same optimizing process.
