In the standard analysis of economic institutions - which include social conventions, the working rules of an economy, and entitlement regimes (property relations) - economists invoke the same theories they use when analyzing individual behavior. In this profoundly innovative book, Daniel Bromley challenges these theories, arguing instead for 'volitional pragmatism' as a plausible way of thinking about the evolution of economic institutions. Economies are always in the process of becoming. Here is a theory of how they become. Bromley argues that standard economic accounts see institutions as mere constraints on otherwise autonomous individual action. Some approaches to institutional economics - particularly the 'new' institutional economics - suggest that economic institutions emerge spontaneously from the voluntary interaction of economic agents as they go about pursuing their best advantage. He suggests that this approach misses the central fact that economic institutions are the explicit and intended result of authoritative agents - legislators, judges, administrative officers, heads of states, village leaders - who volitionally decide upon working rules and entitlement regimes whose very purpose is to induce behaviors (and hence plausible outcomes) that constitute the sufficient reasons for the institutional arrangements they create. Bromley's approach avoids the prescriptive consequentialism of contemporary economics and asks, instead, that we see these emergent and evolving institutions as the reasons for the individual and aggregate behavior their very adoption anticipates. These hoped-for outcomes comprise sufficient reasons for new laws, judicial decrees, and administrative rulings, which then become instrumental to the realization of desired individual behaviors and thus aggregate outcomes.
