A large number of bank failures occurred in transition countries during the 1990s and at the beginning of the 2000s. These were related to increases in non-performing loans and deteriorated cost efficiency of banks. This paper addresses the question of the causality between non-performing loans and cost efficiency in order to examine whether either of these factors is the deep determinant of bank failures. We extend the Granger-causality model developed by [Berger, A., DeYoung, R., 1997. Problem loans and cost efficiency in commercial banks. J. Banking Finance 21, 849–870] by applying GMM dynamic panel estimators on a panel of Czech banks between 1994 and 2005. Our findings support the bad management hypothesis, according to which deteriorations in cost efficiency precede increases in non-performing loans. Banking supervisors should consequently focus on enhanced cost efficiency of banks in order to reduce the likelihood of bank failures in transition countries.

Using a large sample of firms from nine European countries, this study examines the relationship between bank efficiency and the cost of credit for borrowing firms. We hypothesize that bank efficiency – the ability of banks to operate at lower costs – is associated with lower loan rates and thus lower cost of credit. Combining firm-level and bank-level data, we find support for this prediction. The effect of bank efficiency on the cost of credit varies with firm and bank size. Bank efficiency reduces the cost of credit for SMEs, but does not exert a significant influence for either micro companies or large firms. Furthermore, the effect is driven by large banks, where improvements in bank efficiency tend to be strongly associated with lower cost of credit. We also find that lower bank competition facilitates the transmission of greater bank efficiency to lower cost of credit. Overall, our results indicate that measures that increase bank efficiency can foster access to credit.

This study examines how bank risk influences employee wage compensation, disentangling the effects of risk exposure and leverage. Using data from U.S. commercial banks (1990–2022), we find that higher bank risk—measured by earnings volatility, default probability, and credit risk—is associated with higher wages, alongside wage effects linked to monitoring incentives from greater capitalization. This relationship is most pronounced in smaller, less-capitalized banks, under favorable economic conditions, and when bank concentration is low—contexts where employees have greater bargaining power. Overall, bank wages reflect both compensation for job insecurity and monitoring-related incentives, offering insight into employee pay as a signal of bank fragility.

Despite the extensive debate on the effects of bank competition on economic welfare and growth, only a handful of single-country studies deal with the impact of bank competition on the cost of credit. We contribute to the literature by investigating the impact of bank competition on the cost of credit in a cross-country setting. Using a panel of firms from 20 European countries covering the period 2001–2011, we consider a broad set of measures of bank competition, including two structural measures (Herfindahl–Hirschman index and CR5), and two non-structural indicators (Lerner index and H-statistic). We find that bank competition increases the cost of credit and observe that the positive influence of bank competition is stronger for smaller companies. Our findings accord with the information hypothesis, whereby a lack of competition incentivizes banks to invest in soft information and conversely increased competition raises the cost of credit. This positive impact of bank competition is however influenced by the institutional and economic framework, as well as by the crisis.
