Performance Based Pay

We examine the effect of performance-based pay on misreporting intended to benefit a social mission. We show that performance-based pay decreases people's propensity to misreport for a social mission in a not-for-profit setting (Experiment 1). We similarly show that, in a for-profit setting, performance-based pay also decreases misreporting propensity for a social mission, though not for a non-social mission (Experiment 2). Finally, using a framed field experiment with participants attending a conference hosted by a real charity, we show that performance-based pay reduces actual misreporting when misreporting leads to more donations for the charity (Experiment 3). These results are consistent with our theory suggesting that, relative to fixed pay, performance-based pay imposes additional costs on misreporting employees' self-concepts of benevolence and honesty.

Arthropod Pests

AbstractSilicon (Si) is known to have a role in constitutive plant defence against arthropod pests, and recent work has illustrated involvement in induced plant defences. The present tri-trophic study tested the hypothesis that Si increases natural enemy attraction to pest-infested plants and improves biological control. Cucumber plants treated with potassium silicate (Si+) and untreated control plants (Si−) were maintained in separately vented glasshouse compartments. Y-tube olfactometer studies showed that adult Dicranolaius bellulus were significantly more attracted to Si+ plants upon which Helicoverpa armigera larvae had fed compared with Si−, pest-infested plants. Predators were not significantly more attracted to Si+ plants when comparing uninfested cucumbers. In a field experiment, we placed H. armigera-infested and uninfested Si+ and Si− cucumber plants in a lucerne stand. Removal rates of H. armigera egg baits showed predation was greater for Si+ infested plants than for other treatments. Results suggest that Si applied to plants with a subsequent pest infestation increases the plants' attractiveness to natural enemies; an effect that was reflected in elevated biological control in the field.
