In particular, we investigate two heterogeneous treatment effect: (1) differential among journals grouped by academic field, publisher, and tier; (2) effects as a function propensity to be treated. The results are robust number sensitivity checks falsification tests. Our findings shed new light can help stakeholders in decision adopting policy.
