Bank Entry during the Antebellum Period
研究美国自由银行时期自由与非自由银行州的银行进入和资本形成，发现自由银行法显著增加了银行进入，且非自由州在邻州通过该法后也放宽了进入政策。
A recent study by Kenneth Ng (1988) challenges the view that free banking laws lowered barriers to entry. The authors' study examines bank entry and capital formation in free and nonfree banking states during the free banking period. A competitive model is developed and used to test if barriers were lowered in free banking states. The evidence indicates that entry significantly increased after the enactment of the free banking laws and that entry policy in nonfree banking states appeared to have been 'liberalized' when the free banking laws were enacted in other states.
