The existence of social ties between co-workers affect many aspects of firm and worker behavior, such as how workers respond to a given set of incentives, the optimal compensation structures for workers at different tiers of the firm hierarchy, and the optimal organizational design for the firm....

We consider a principal-agent model of adverse selection where, in order to trade with the principal, the agent must undertake a relationship-specific investment which affects his outside option to trade, i.e. the payoff that he can obtain by trading with an alternative principal. This creates a...

We present evidence on the effect of social connections between workers and managers on productivity in the workplace. To evaluate whether the existence of social connections is beneficial to the firm's overall performance, we explore how the effects of social connections vary with the strength...

Despite their potentially strong impact on poverty, agricultural innovations are often adopted slowly. Using a unique household dataset on sunflower adoption in Mozambique, we analyse whether and how individual adoption decisions depend upon the choices of others in the same social networks....

We use personnel data to compare worker productivity under a relative incentive scheme, where worker pay is negatively related to the average productivity of co-workers, with productivity under piece rates – where pay is based on individual productivity alone. We find that for the average...

We document the establishment and evolution of a cooperative norm among workers using evidence from a natural field experiment on a leading UK farm. Workers are paid according to a relative incentive scheme under which increasing individual effort raises a worker's own pay but imposes a negative...

We present evidence from a firm level experiment in which we engineered an exogenous change in managerial compensation from fixed wages to performance pay based on the average productivity of lower-tier workers. Theory suggests that managerial incentives affect both the mean and dispersion of...

We analyze the role of the marriage contract. We first formalize three prominent hypotheses on why people marry: marriage provides an exogenous payoff to married partners, it serves as a commitment device, and it serves as a signaling device. For each theory we analyze how a reduction in the...

This paper develops a model of search and learning in marriage markets to analyze how a liberalization of divorce laws affects marriage market outcomes. In particular we analyze how the move from mutual consent divorce to unilateral divorce affects marriage rates, the composition of those who...

We present evidence on whether workers have social preferences by comparing workers' productivity under relative incentives, where individual effort imposes a negative externality on others, with their productivity under piece rates, where it does not. We find that the productivity of the...
