This study examines how institutional logics interplay in a cross-sector social partnership that manages refugee integration in a rural district in Germany. In an inductive 15-month case study that drew on interviews and observations, we observe the dynamic materialization of institutional logics in day-to-day practices and an increasing contradiction and even rivalry between community- and market-based institutional logics over time. As a result, we delineate a model explaining the interplay of institutional logics along two dimensions: the dominance of one salient logic and whether conflicts arise among logics. Our analysis also addresses the unifying properties of community as an institutional logic, especially in the context of urgency conditions. In addition, we show the influence of exogenous events and their media coverage on the interplay and conflicts of institutional logics. By unfolding the complexity of refugee integration—one of the global grand challenges of the present—we deepen the current understanding of the specific challenges addressed by cross-sector social partnerships.
