We explore the joint determination of product differentiation strategy and corporate leverage in a setting where (i) product differentiation is valued by customers; (ii) debt is necessary to discipline managers; and (iii) liquidation is costly for customers, in particular, when products are...

Using a game theoretical model on firms' simultaneous investments in product and process innovation, we deduct and empirically test hypotheses on the optimal R&D portfolio, investment, performance, and dynamic efficiency of R&D for acquisitions and in independently competing firms. We use...

We characterize the product line choice and pricing of a monopolist as the upper envelope of net marginal revenue curves to the individual product demand functions. The equilibrium product varieties to include in a product line are those yielding the highest upper envelope. In a central case...
