High oil prices are normally expected to stimulate exploration and the development of new oil and gas fields. But over the last few years, financial analysts have focused strongly on shortterm accounting return (RoACE) for benchmarking and valuation, and this has led to high capital discipline...

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...

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 analyze relational contracts for a set of agents when either (a) only aggregate output or (b) individual outputs are observable. A team incentive scheme, where each agent is paid a bonus for aggregate output above a threshold, is optimal in case (a). The team's efficiency may increase...

In repeated games, it is hard to distinguish true prosocial behavior from strategic instrumental behavior. In particular, a player does not know whether a reciprocal action is intrinsically or instrumentally motivated. In this paper, we experimentally investigate the relationship between...

We study to what extent collusive behavior is affected by the awareness of negative externalities. Theories of outcome-based social preferences suggest that negative externalities make collusion harder to sustain than predicted by standard economic theory, while sociological theories of social...

In this paper we present results from a large scale real effort experiment in an online labor market investigating the effect of performance pay and two common leadership techniques: Positive expectations and specific goals. We find that positive expectations have a significant negative effect...

We present an experimental study on how people take risk on behalf of others. We use three different elicitation methods, and study how each subject makes decisions both on behalf of own money and on behalf of another individual’s money. We find a weak tendency of lower risk-taking with...

This paper develops a simple economic model to examine how leadership styles in organizations depend on the prevailing wage-setting conditions for workers. In particular, we examine a leader who can - in addition to the use of monetary incentives - motivate a worker by adopting leadership styles...
