The Credit Effects of Monetary Policy: Evidence Using Loan Commitments
利用商业银行贷款合同差异，发现紧缩货币政策后无承诺贷款减少，有承诺贷款不变或增加，表明货币政策通过信贷供给渠道影响企业支出。
In addition to the usual channels, monetary policy may affect spending by changing the supply of bank loans and the creditworthiness of borrowers. This paper tests for these credit effects using a contractual difference across commercial bank loans. The author finds that bank loans not made under a commitment slow after tight policy, while loans under commitment accelerate or are unchanged. This divergence coincides with reports of tighter credit by lenders and by small firms, suggesting the divergence reflects a reduction in the supply of credit to the firms without commitments, rather than a reduction in their demand for loans.
