allow for the opposite. Experimental results are mixed, and so far have not been corrected for publication bias and model … obtained. We use novel nonlinear techniques to correct for publication bias and em- ploy Bayesian model averaging to account … for model uncertainty. The corrected estimates are zero or tiny across contexts of field experiments, including …
