It lists four identification challenges and answers each with features of the shale setting. It previews results from two DiD designs with magnitudes, then rules out traditional distortions. Two candidate channels follow: covenants and cash flow, which are rejected, and collateral, which is supported. Robustness tests are mentioned, contributions are positioned against three literatures, and a roadmap closes the introduction. The body has a single data and institutional section, a long results section with subsections on alternative explanations, robustness, and channels, and a short conclusion that restates results and implications.",
