If institutional heterogeneity tends overall to reduce survival chances, it may also persist and be harnessed to good use. This article investigates this ambivalence by looking at how institutional heterogeneity emerges, develops, and survives. An inductive study of the "Metropolitan Opera" archives suggests that what enables heterogeneity to survive and to withstand the pressure for homogenization is its inherent potential for "multivocality." The analysis shows how institutional discrepancies were bridged over through an opportunistic, "multivocal" action pattern, whereby the organization maneuvered between conflicting institutional demands, seeking to minimize dependence on any single constituency or evaluation principle. Maintaining discretionary options is essential in multi-dimensional space, where ambiguity makes optimization impractical. The trade-off in this action pattern includes remarkable adaptability and operational inefficiencies.Keywords Institutional heterogeneity . Survival . Multivocality . Opera What makes new organizations viable? The dominant thinking on founding and reproduction emphasizes the role of fit and continuity. New forms emerge when wellendowed actors see an opportunity to realize a set of interests and manage to frame them aptly within the social context, convincing others to go along (Fligstein 1996). The founding process involves assembling of resources, legitimating the new form and integrating it with the prevalent institutional order (Haveman and Rao 1997, p. 1614). Selection pressures and processes of socialization, interaction, and repetition (cf. DiMaggio and Powell 1983) serve to reinforce the reproduction of successful elements over time. Reproduction is aided by the difficulty of changing course once investments have been made in technologies and routines (Hannan and Freeman 1984).
