Experiments About Institutions

Institutions are a key determinant of economic growth, but the critical junctures in which institutions can change are not precisely defined. For example, such junctures are often identified ex post, raising several methodological problems: a selection on the outcome of institutional change; an inability to study beliefs, which are central to coordination and thus the process of institutional change; and an inability to conduct experiments to identify causal effects. We argue that critical junctures are identifiable in real time as moments of deep uncertainty about future institutions. Consistent with this conception, the papers reviewed (a) examine changes to institutions, i.e., the fundamental rules of the game; (b) are real-time studies of plausible critical junctures; and (c) use field experiments to achieve causal identification. We also advocate for more systematic measurement of beliefs about future institutions to identify critical junctures as they happen and provide an empirical proof of concept. Such work is urgent given contemporary critical junctures arising from democratic backsliding, state fragility, climate change, and conflicts over the rights of the marginalized.
