Abstract

The purpose of this research was to investigate the effectiveness of a probabilistic reward scheme to motivate workers and increase their performance. Across seven experiments (three of which are in the online appendices) testing three different real effort tasks, we compared two novel probabilistic reward schemes with two traditional non-probabilistic reward schemes. In our flagship “single lottery” probabilistic scheme, worker performance was associated with the accumulation of lottery tickets in the worker’s own personal lottery with a moderate jackpot on offer. It was possible for the worker to accumulate all tickets and thus guarantee the jackpot. We found that the single lottery scheme increased motivation and performance relative to other probabilistic and non-probabilistic schemes with the same expected values. There was also evidence that the single lottery scheme was particularly effective for lower-ability workers relative to the non-probabilistic schemes. We argue that the single lottery scheme uniquely benefited from optimism bias and the goal gradient effect. Considering perceptions of (un)fairness associated with probabilistic reward schemes – at least at first – we discuss what labor contexts are appropriate for the introduction of a probabilistic reward scheme.
