“…This analysis is particularly useful when the conditional distribution does not have a standard shape, such as an asymmetric, fat-tailed, or truncated distribution. Consequently, quantile regression was recently employed in various strands of the finance and banking literature, including banking risk and regulations (Klomp and de Haan, 2012), the herding behavior in stock markets (Chiang et al, 2012), capital structure (Fattouh et al, 2005), bankruptcy prediction (Li and Miu, 2010), ownership and profitability (Li et al, 2009), the relationship between stock price index and exchange rate (Tsai, 2012), and credit risk (Schechtman and Gaglianone, 2012). 1 In the context of our study, quantile analysis provides an ideal tool to examine bank efficiency heterogeneity, departing from conditional-mean models.…”
