jfr-heterogeneity

separate

Use when the heterogeneity analysis of a 《金融研究》 (Journal of Financial Research) manuscript is too coarse or atheoretical — to cut along finance-relevant dimensions (ownership, bank type, market segment, financing constraint, region) that the mechanism predicts, not arbitrary splits.

When to use

• heterogeneity analysis of a 《金融研究》 manuscript
• cutting along finance-relevant dimensions
• ownership, bank type, market segment, financing constraint, region
• dimensions predicted by the mechanism
• group coefficient difference tests
• aligning heterogeneity with mechanism conclusions

When not to use

• arbitrary splits
• data fishing
• splits unrelated to the mechanism
• stacking splits without theoretical basis
• claiming heterogeneity based only on individual group significance
