1 Organizing for Market Constitution: Uncertainty and Collective Institutional Entrepreneurship

This conceptual paper presents market constitution as a process of dealing with uncertainty at multiple levels of the market as a transaction system supported by actors, networks and institutions. It sketches a framework for analyzing if and how actors can organize social networks with the aim of shaping the institutions in which market transactions are embedded. This notion of collective institutional entrepreneurship emphasizes agency besides emergence, and it should play an important part in broader theories of market constitution. However, it also raises challenging questions on how collective institutional entrepreneurship is conceptualized and organized. Keywords: agency, cooperation, institutional theory, markets, uncertaint
