This paper investigates how compensation structure affects performance in a simple but effort-consuming task. In this experimental study, the subjects were asked to multiply two-digit numbers for 40 min and were paid using either a linear (with different pay for performance sensitivities) or a convex (option-based) compensation mechanism. We found that per-unit wage has a non-linear positive effect on performance: whereas increasing per-unit compensation from $0 to $0.02 or from $0.05 to $0.15 has virtually no effect on performance, an increase from $0.02 to $0.05 results in higher productivity. We also found that option-based compensation results in better performance.
