Field-level evaluation practices and practice experimentation: Social impact bonds and market logic encroachment in the field of social integration

Abstract

The authors contribute to practice-driven institutionalism by examining how the introduction of new field-level evaluation practices may facilitate encroachment of highly institutionalized organizational fields by new institutional logics. The authors conducted an inductive study of a trial of social impact bonds in the field of social integration services in Finland. Our analysis elaborates how new field-level evaluation practices created an experimental space that induced organizational practice experimentation, reconfigured relationships among field members, and lowered the barriers to entry for new organizations. The authors theorize how evaluation practices may create experimental spaces by suspending the carriers of established logics and legitimizing institutional innovations. The authors further elaborate how such spaces can bring about a parallel “shadow field” by inducing bottom-up experimentation aligned with a new institutional logic.
