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...

Traditionally, it has been argued that profit sharing can increase employment and welfare because it lowers marginal labour costs without reducing total cost or labour income. In this paper, we show that profit sharing can also represent a Pareto-improvement if labour supply is excessive due to...

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 compare performance in a word based creativity task under three incentive schemes: a flat fee, a linear payment and a tournament. Furthermore, we also compare performance under two control tasks (Raven’s advanced progressive matrices or a number-adding task) with the same treatments. In all...

This study investigates whether excess effort to climb a career ladder justifies policy interventions. The answer depends on whether the government is able to levy a higher tax burden on career workers than on non-career workers. Both a tax on top income aimed at lowering the rewards 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...

Awards are widespread in all countries and are prevalent both in the public sphere and in the private sector. This paper argues, and empirically supports, that awards serve public functions and economists should take them seriously. Using a unique cross-country data set, we suggest that awards...

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...
