Adding some data on the financial information framework (Bank Regulation and supervision Database), our study shows that financial information rules produce significant bias in reportedefficiency. Following less conservative standards, IAS or USGAAP, banks show lower levels of efficiency than banks in countries with more conservative standards. Also, in countries where disclosure of risk management policies is mandatory, banks seem to be less efficient. LK https://hdl.handle.net/10612/19610 UL https://hdl.handle.net/10612/19610 DS BULERIA.
