While confounding factors typically jeopardise the possibility of using observational data to measure peer effects, field experiments offer the possibility of obtaining clean evidence. In this Paper we measure the output of four randomly selected groups of individuals who were asked to fill...

The, often observed, positive correlation between incentive intensity and risk has been explained in two ways: the presence of transaction costs as determinants of contracts and the sorting of risk-tolerant individuals into firms using high-intensity incentive contracts. The empirical importance...

We investigate the economic relevance and the composition of gifts within a firm where output is contractible. We develop a structural econometric model that identifies workers' optimal reaction to monetary gifts received from their employer. We estimate the model using data from two separate...

We present results from a field experiment designed to measure the importance of managerial commitment to a contract within a firm that pays its workers piece rates. In the tree planting industry the piece rate paid to workers is determined as a function of the difficulty of the terrain to be...

We conduct a field experiment where we vary both the presence of a gift-exchange wage and the effect of the worker's effort on the manager's payoff. Results indicate a strong complementarity between the initial wage-gift and the agent's ability to "repay the gift". We control for differences in...

Incentive schemes affect performance and priorities of agents but, in reality, they can be complicated even for simple tasks. We analyze the effects of the salience of incentives in a team production setting where the principal has an interest in quantity and quality of output. We use data from...

We present results from a field experiment testing the gift-exchange hypothesis inside a tree-planting firm paying its workforce incentive contracts. Firm managers told a crew of tree planters they would receive a pay raise for one day as a result of a surplus not attributable to past planting...
