This paper reviews the literature concerning the evolution of cultural traits in general and preferences in particular, and the emergence and persistence of rules or norms, from a family per-spective. In models where every new person is effectively the clone of an existing one (either a parent...

This paper reviews the literature concerning the evolution of cultural traits in general and preferences in particular, and the emergence and persistence of rules or norms, from a family perspective. In models where every new person is effectively the clone of an existing one (either a parent or...

I study a repeated principal-agent game with long‐term output contracts that can be renegotiated at will. Actions are observable but not contractible, so they can only be incentivized through implicit agreements formed in equilibrium. I show that contract renegotiation is a powerful tool for...

We propose a theory of ex post inefficient renegotiation that is based on loss aversion. When two parties write a long-term contract that has to be renegotiated after the realization of the state of the world, they take the initial contract as a reference point to which they compare gains and...

We consider a simple trading relationship between an expectation-based loss-averse buyer and profit-maximizing sellers. When writing a long-term contract the parties have to rely on renegotiations in order to ensure materially efficient trade ex post. The type of the concluded long-term contract...

This paper develops a model of child custody based on an incomplete-contract approach to the allocation of property rights. Because of the presence of transaction costs in marriage, altruistic parents cannot contract upon the investments they make into their children, but can reduce the...

I propose a theory of debt maturity as an incentive device to motivate innovation when contracts are fundamentally incomplete and shaped by ex-post renegotiation. The financing of innovative firms must balance two goals. On the one hand, since innovation is inherently risky, the entrepreneur...

We show that the descendants of ancient farmers may have an interest in marrying among themselves, and thus maintaining the gendered division of labour, originally justified on comparative-advantage grounds by the advent of the plough, even after they emigrate to a modern industrial economy...

It is well known that delegating the play of a game to an agent via incentive contracts may serve as a commitment device and hence provide a strategic advantage. Previous literature has shown that any Nash equilibrium outcome of an extensive-form principals-only game can be supported as a...
