Fairness and motivation

Summary

In "Fairness and motivation," Armin Falk critically examines the conventional economic assumption that individuals are primarily motivated by maximizing material payoffs, proposing instead that social preferences like fairness and trust are fundamental drivers of human motivation. The paper synthesizes a growing body of evidence from various research methods to support this view, highlighting that motivation should not solely rely on extrinsic incentives and money. The methodology draws upon diverse empirical evidence, including findings from laboratory and field experiments, surveys, observational data, and neuroeconomic research, sometimes complemented by neuroscientific methods like functional magnetic resonance imaging (fMRI). For instance, the paper discusses an employer-worker experiment where workers performed a tedious task, and variations in heart rate were recorded in response to perceived fairness of pay, demonstrating a link between unfairness and physiological stress. This interdisciplinary approach allows for a robust exploration of the psychological underpinnings of incentives and their effects on behavior. The paper's findings indicate that kind and fair treatment significantly motivates workers, often leading to effort levels beyond the contractually enforceable minimum. Conversely, perceived unfairness can result in negative outcomes, including costly punishment of the unfair party, shirking, sabotage, and even physiological stress responses indicative of adverse health effects. A key implication is that explicit performance incentives may sometimes backfire, suggesting that policy advice based purely on simplistic economic assumptions can be counterproductive. The research underscores that respecting employees is not only ethically sound but also yields positive economic benefits for both workers and firms. Therefore, firms emphasizing fair treatment in wages and overall work environment can achieve better results.
