  • Margarida Catalão-Lopes

Abstract

Why do some firm acquisitions give rise to a single brand name, and why, following others, all brands subsist? What are the welfare consequences of each option upon joining firms, rivals, and consumers from each of these groups? How do the choice of the strategigc variable (price or quantity) and the demand cross effects influence the results? This paper addresses these issues.
