5. Discussion and conclusion
We investigate the effects of two incentive features − a bonus versus a penalty and an outcome’s fairness − on the assumption that via cognitive framing, they influence risk and effort decisions. Our predictions are based on two influential theories: prospect theory (Kahneman and Tversky, 1979; Kahneman, 2003) and organizational justice theory (Adams, 1963; Akerlof and Yellen, 1990). These theories share a common feature: a reference point against which people determine the utility of their outcome. Both theories have been extensively tested and convincingly confirmed, but only for a single behavioral outcome − either risk-taking or exerting effort. We tested their effects on behavior that is usually beyond the scope of each theory and in a multiperiod setting. We were interested in whether social comparisons matter for risk-taking and whether gain and loss domains matter in exerting effort. Our more specific research question addressed how these frames combine in joint decisions about risk and effort. Prior empirical evidence is inconsistent showing that a variety of incentive system characteristics may invoke the same cognitive frames (i.e., gain and loss domains). But more importantly, there is no evidence on the interactive or additive effects of various frames, and whether the cues are consistent or conflicting.
