Seong-Young's dissertation abstract reads:
This dissertation presents a collection of three essays which focus on the relationships between alliance portfolios, firm factors, and performance. Because these relations remain understudied, I tackle them through three empirical studies in the semiconductor industry. The first essay explores how diversity in alliance portfolios and firm factors influence firm performance in the context of the U.S. semiconductor industry (1995–2009). Findings suggest that three types of diversity – alliance functions, technological resources, and positional resources – have varying effects on focal firm's market
performance, while those links are contingent upon the firm's market experience. These findings contribute to the debate on portfolio diversity in alliance portfolios literature. The second essay investigates the relationship between partners' bargaining positions, a focal firm's resources, and its performance. Findings in the global semiconductor industry (1997–2007) suggest that the effect of relative bargaining power on performance depends upon a firm's relative resource commitment and portfolio cohesion between partners. These findings contribute to alliance portfolio literature, by highlighting a focal firm's aspect in the context of partners’ endowments. The third essay examines the effect of resources fit between a firm and its partners on firm performance. Analyses using data of the global semiconductor firms (1997– 2007) show that increasing complementarity of technological resources and compatibility of organizational resources influences firm’s profitability. These findings contribute to alliance portfolios literature, by extending the current debate on partner endowment to resource fit between firm and partners.
Seong-Young has already presented previous versions of these three empirical studies at various conferences, including Strategic Management Society and Academy of Management. Seong-Young has just started his new academic career as an assistant professor at ESC Rennes.
