The Effect of Alliance Portfolio Size on Firm Performance Revisited: The Role of Firm- and Portfolio-Level Contingencies

by Barreto Tais Siqueira

Alliance portfolios, or a firm collection of simultaneous alliances, have becomecommon phenomena particularly in technology industries. These portfolios have beenfound to have a significant impact on firms financial performance. At the same time,there is little consensus regarding the direction of this effect. Findings have shownpositive, negative, curvilinear, and non-significant relationships. In this dissertation, Iemployed an organizational learning perspective to investigate the effect of allianceportfolio size on firm financial performance. Using a sample of 343 firm-yearobservations in the U.S. software industry, I explored portfolio- and firm-levelcharacteristics as moderators of this relationship. Findings provide evidence for acurvilinear, inverted U-shaped relationship between portfolio size and firm performancethat is moderated by the timing of the alliances within the portfolio and by the firms TopManagement Team (TMT) turnover. 2017 Degree granted: Dissertation (Ph.D.) FloridaAtlanticUniversity, 2017.
