What Drives Bank Competition? Some International Evidence
利用50个国家的银行数据，衡量银行竞争程度，发现外资银行进入多、准入和业务限制少的体系竞争更激烈，且竞争与集中度无关。
Using bank-level data, we apply the Panzar and Rosse (1987) methodology to estimate the extent to which changes in input prices are reflected in revenues earned by specific banks in 50 countries' banking systems. We then relate this competitiveness measure to indicators of countries' banking system structures and regulatory regimes. We find systems with greater foreign bank entry and fewer entry and activity restrictions to be more competitive. We find no evidence that our competitiveness measure negatively relates to banking system concentration. Our findings confirm that contestability determines effective competition especially by allowing (foreign) bank entry and reducing activity restrictions on banks.
