Reputational losses and operational risk in banking
研究了1994至2008年间欧美银行宣布操作损失后的声誉影响，发现欺诈事件和特定业务线（交易销售、支付结算）导致显著声誉损失，且欧洲损失高于北美。
Reputation is a key asset for any company whose affairs, like those of banks, are based on trust. Despite its importance, the number of studies dealing with reputational risk in the financial industry is still limited. We estimate the reputational impact of announced operational losses for a large sample of banks (both commercial and investment) in Europe and the USA between 1994 and 2008. By conducting an event study, we show that substantial reputational losses occur following announcements of ‘pure’ operational losses. We provide evidence that ‘fraud’ is the event type that generates the greatest reputational damage. ‘Trading and sales’ and ‘payment and settlement’ are the two business lines determining considerable reputational losses. We also found that losses are higher in Europe than in North America.
