Product Choice and Product Switching
This paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we present on the importance of product switching by U.S. manufacturers. Two-thirds of continuing firms change their product mix every five years, and product switches involve more than 40% of firm output and almost half of existing products. The theoretical model incorporates heterogen...
متن کاملMulti - Product Firms , Industry Mix , and Product Switching ∗ Andrew B . Bernard
This paper examines firms and the products they manufacture — and abandon — over time. We find strong relationships between product switching and a number of microand macroeconomic variables, including firm performance, aggregate manufacturing growth and product diversification. Most importantly, product switching is a very important — and active — margin of firm adjustment that is positively c...
متن کاملNot for Publication: Technical Appendix to Multi-Product Firms and Product Switching
This technical appendix contains a more detailed exposition of the model and additional supplementary material for the paper. The remainder of the technical appendix is structured as follows. Section B develops the model. Section C derives the features of product switching at the rm, product and rm-product level that we examine empirically in the paper. For further economic intuition, Section...
متن کاملProbing the future: Mobilising foresight in multiple-product innovation firms
With rapid changes in technology and intense competition in the business environment the importance of cultivating and sustaining foresight in multiple-product innovation firms has been propelled to unprecedented heights. Yet, research on the processes through which such firms mobilise foresight in their working environment remains scarce. This paper seeks to explore the different processes thr...
متن کاملMultiproduct Firms and Product Differentiation: a Survey
We start the survey by reviewing the implications of horizontal and vertical product differentiation on market structure under the assumption of single-product firms. Then, we analyse the main results of the multi-product firm models, both when variants are assumed differentiated in vertical attributes only and when variants are assumed differentiated in two dimensions (vertical and horizontal)...
