Economics Envy: The Dual Calculus of Human Motivation ← Series Home Key Takeaways Fair Wage-Effort Hypothesis: Workers supply fraction of normal effort when actual wage less than perceived fair wage. Mechanism: Underpayment causes anger, reducing labor input. Antagonistic Outcomes: Comparative concern causes output restriction, efficiency losses, unemployment, sabotage. Wage Compression: FWEH explains observed wage compression, making internal structures more egalitarian. Reference Groups: Fair wage based on comparisons with co-workers in same firm. The Fair Wage-Effort Hypothesis Comparative concerns translate into measurable inefficiency within the workplace. Managers and policymakers must recognize that competition quickly undermines group performance if fairness is absent. The Fair Wage-Effort Hypothesis (FWEH), motivated by equity theory in social psychology and social exchange theory in sociology, precisely quantifies this behavioral response. This hypothesis states that workers possess a conception of a fair wage ($w^*$); if the actual wage ($w$) falls below this standard, workers respond by proportionally withdrawing effective labor input. This behavior follows the functional form: $e = \min(w/w^*, 1)$, where $e$ is effective effort supplied and 1 denotes normal effort.
