Effects of uncertainty on recipients reward/punishment behavior. The constant term captures recipients average reward/punishment behavior in the equal wealth condition when participants have certainty about the distribution of recipients’ endowments. Regressions control for individual level fixed effects; standard errors are heteroskedasticity-robust and clustered at the participant level. F statistics and corresponding p values from a Wald test of joint significance of β₃, β₄ and β₅ for each regression are reported below the table.

^*Significant at the 10% confidence level,
