We examined responses to institutional complexity by studying when and how organizations respond to a coercive institutional demand from a powerful constituent when other important constituents do not accept the demand as legitimate. We experimentally manipulated institutional complexity and gauged the time to compliance of 100 childcare managers in the Netherlands, then asked them to describe and explain their anticipated responses to multiple pressures. We found that institutional complexity leads decision makers to delay compliance, but usually not passively: decision makers used the time before compliance to attempt to reduce institutional complexity by neutralizing opposing pressures, challenging the coercive pressure, adapting the practice to suit opponents and their own personal beliefs, and/or waiting to see how the situation would unfold as multiple parties influenced one another. We found two factors influenced decision-makers choice of responses: their interpretation of institutional complexity and their personal beliefs toward the practice itself. Our findings contribute to an emerging understanding of how decision makers interpret and respond to institutional complexity, and complement recent studies in the institutional complexity literature.
