We interpret the psychology literature on social identity and examine its implications in a population partially composed of such agents. We model a population of agents from two exogenous and well defined social groups. Agents are randomly matched to play a reduced form bargaining game. We show...

Using a unique sample of comparable online and in-person loan transactions, we study the determinants of arm's-length and inside lending focusing on the differential information content across debt types. We find that soft private information primarily underlies relationship lending whereas hard...

Two issues in land tenure contracts in agriculture that have vexed economists are (1) the appearance and co-existence of multiple contracts, often in adjoining plots of land and (2) the choice of a share-cropping contract because a share contract being analogous to a proportional tax, is...

We thank three anonymous referees for thoughtful comments and suggestions which we found very constructive and helpful. We are particularly grateful to the editor, Al Klevorick, for his advice and painstaking guidance through the multiple revision process. We thank Robert Barsky, Susanto Basu,...

We offer the first direct evidence of an implicit contract in a goods market. The evidence we offer comes from the market for Coca-Cola. We demonstrate that the Coca-Cola Company left a substantial amount of written evidence of its implicit contract with its consumers-a very explicit form of an...

We develop a model of relational contracts with moral hazard and asymmetric persistent information about an employee's type. We find that the form of the optimal contract depends on the job characteristics as well as the distribution of employees' talent. Bonus contracts are more likely to be...

This paper analyzes the design of innovation contests when the quality of an innovation depends on the research approach of the supplier, but the best approach is unknown. Diversity of approaches is desirable because it generates an option value. In our main model with two suppliers, the buyer...

This paper analyzes the design of innovation contests when the quality of an innovation depends on the research approach of the supplier, but the best approach is unknown. Diversity of approaches is beneficial because of the resulting option value. An auction induces the social optimum, while a...

This paper analyzes the design of innovation contests when the quality of an innovation depends on the research approach, but the best approach is unknown. Inducing a variety of research approaches generates an option value. We show that suitable contests can induce such variety. The...
