We use surveys, laboratory experiments and administrative data to study how heterogeneity in the perceived immorality of work and in workers' aversion to acting immorally impact labor market outcomes. Immoral work is associated with higher wages, both in administrative data and in causal experimental evidence. Individuals more willing to engage in immoral conduct find employment in firms and industries perceived as immoral less aversive and have higher employment rates in immoral work in the laboratory. These phenomena appear to be driven by impure social motives, reflecting a desire not to be involved with immoral work, rather than by consequentialist concerns.

We investigate the causal impact of public discourse on socially responsible market behavior. Across three laboratory experiments, having market participants engage in public discourse generally increases market social responsibility. These positive impacts are robust to variation in several characteristics of the discourse. We provide evidence that discourse strengthens beliefs that others support socially responsible exchange. However, relaxing requirements to engage in discourse sharply reduces its effectiveness. Our findings suggest that campaigns encouraging discussion of appropriate market behavior can have sizable impacts on addressing inefficiencies due to market failures but that policies encouraging broad public engagement may be important.
