Our theory of cultural-institutional persistence and innovation is based on uncoordinated updating of individual social norms and contracts, so that both culture and institutions are endogenous. We explain why Pareto-dominated cultural-institutional configurations may persist over long periods...

We construct a fully specified extensive form game that captures competitive markets with adverse selection. In particular, it allows firms to offer any finite set of contracts, so that cross-subsidization is not ruled out. Moreover, firms can withdraw from the market after initial contract...

We experimentally investigate cooperation within a finitely repeated public goods game framework where peer punishment is possible but, unlike previous work, in each round access to sanctioning power is exclusively awarded to the group’s top contributor. We compare this mechanism with a...

We study a fiscal policy model in which the government is present-biased towards public spending. Society chooses a fiscal rule to trade off the benefit of committing the government to not overspend against the benefit of granting it flexibility to react to privately observed shocks to the value...

We study how cooperation-enforcing institutions dynamically affect values and behavior using a lab experiment designed to create individual specific histories of past institutional exposure. We show that the effect of past institutions is mostly due to “indirect” behavioral spillovers:...

Separated powers cannot permanently constrain individual ambitions. Concerns about a government's ability to respond to contemporary and future crises, we show, invariably compromise the principled commitments one branch of government has in limiting the authority of another. We study a dynamic...

Agent-based models typically involve large numbers of interacting individuals with widely differing characteristics, rules of behavior, and sources of information. The dynamics of such systems can be extremely complex due to their high dimensionality. This chapter discusses a general method for...

Social norms are customary or ideal forms of behavior to which individuals in a group try to conform. From an analytical standpoint, the key feature of social norms is that they induce a positive feedback loop between individual and group behavior: the more widely that a norm is practiced by...

We propose a political economy mechanism that explains the presence of fiscal regimes punctuated by crisis periods. Our model focuses on the interaction between successive deficit-biased governments subject to i.i.d. fiscal shocks. We show that the economy transitions between a fiscally...
