We present a model in which a motivator can take costly actions - or what we call motivational effort - in order to reduce the effort costs of a worker, and analyze the optimal combination of motivational effort and monetary incentives. We distinguish two cases. First, the firm owner chooses the...

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 in a naturally occurring labor environment and track whether the performance of workers responds to unexpected wage increases. Specifically, we investigate how the timing of wage increases affects efforts. We find that workers’ performance is about 11% higher for...

This paper studies how social relationships between managers and employees affect relational incentive contracts. To this end we develop a simple dynamic principal-agent model where both players may have feelings of altruism or spite toward each other. The contract may contain two types of...

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. The results indicate a strong complementarity between the initial wage gift and the agent’s ability to “repay the gift”. We collect...

We conduct a field experiment in a controlled work environment to investigate the effect of motivational talk and its interaction with monetary incentives. We find that motivational talk significantly improves performance only if it is accompanied by performance pay. Moreover, performance pay...

A worker’s utility may increase in his own income, but envy can make his utility decline with his employer’s income. Such behavior may call for high-powered incentives, so that increased effort by the worker little increases the income of his employer. This paper uses a principal-agent model...

Empirically, compensation systems generate substantial effort despite weak monetary incentives. We consider reciprocal motivations as a source of incentives. We solve for the optimal contract in the basic principal-agent problem and show that reciprocal motivations and explicit performance-based...

An important aspect in determining the effectiveness of gift exchange relations in labor markets is the ability of the worker to “repay the gift” to the employer. To test this hypothesis, we conduct a real effort laboratory experiment where we vary the wage and the effect of the worker’s...

Behavioral economics documents the importance of status and self-image concerns in the workplace, but is largely silent about how to instrumentalize them to induce effort. Awards - widespread in the corporate sector and elsewhere - are motivators that derive their value from such social...
