Balanced Brand Partnerships and Multidimensional Outcomes: Evidence from Joint Value Creation, Operating Gains, and Dyadic Persistence

Abstract

Partnerships are often evaluated with a single performance lens even though alliance outcomes unfold across several margins at once. The same collaboration can create immediate investor enthusiasm, redistribute gains unevenly across partners, improve operations only after coordination frictions decline, and either stabilize or unravel as market conditions change. This paper develops and estimates a multidimensional framework for partnership outcomes in branded interfirm collaborations. The empirical setting is a large sample of U.S. consumer-market partnerships in which two established firms place their brands on a shared offering or a tightly integrated market program. The analysis combines announcement-period stock market reactions, post-partnership operating performance, and dyadic survival. Rather than treating outcome as a single scalar, the study models joint value creation, distributive balance, and persistence as related but distinct realizations of the same underlying cooperative process. The results indicate that partnerships with higher partner balance, stronger category complementarity, and tighter governance generate superior joint outcomes. On average, announcement-period joint abnormal returns are positive, but the mean obscures substantial heterogeneity. Balanced partnerships earn larger combined abnormal returns, smaller cross-partner return gaps, stronger four-quarter gains in operating margin and sales productivity, and lower termination hazards. Exclusive governance strengthens the effect of balance, whereas repeated commercial exploitation of the secondary brand weakens both short-horizon and medium-horizon performance. The evidence further shows that operating gains are not automatic: they arise primarily when complementarities are present and when governance reduces appropriation risk. The findings support a view of partnership outcomes as a coupled system in which value creation, value allocation, and relationship duration are jointly determined.
