“…Mean while, a positive relationship agrees with the "Information generating hypothesis" that supposes that a greater market power makes it easier to access information and thus contributes to improving banking efficiency. This finding is confirmed by Maudos and De Guevara (2007), Casu and Girardone (2009) and Koetter et al (2011).…”

In this paper, we examine the determinants of cost and revenue efficiency of Malaysian banks over the period [2006][2007][2008][2009][2010][2011][2012]. Three steps are undertaken to study a sample of 17 Islamic banks (IBs) and 20 conventional banks (CBs). In the first step, we assessed the competitiveness of the Malaysian banking sector. After solving the multicollinearity problem, as a second step, we selected three sets of independent variables: bank-specific, industry-specific and macroeconomic variables. In the last step, we estimated the efficiency models with the Feasible Generalized Least Squares (FGLS) method. The obtained results highlighted the importance of regulatory capital and size. As for the effect of competitiveness, it is found to be statistically significant only for revenue efficiency. These results may be useful to political decision-makers and regulatory authorities.

“…There are several studies with various objectives that estimate the marginal cost of firms. Only indicatively, see Hall (1988), Bresnahan (1989), Roeger (1995), Konings et al (2005), and Koetter et al (2012). A common feature of these studies is that they rely on strong assumptions of the functional form, usually without an initial analysis on the properties of their data.…”

This article proposes the estimation of marginal cost of individual firms using semiparametric and nonparametric methods. These methods have a number of appealing features when applied to cost functions. The empirical analysis uses data from a unique sample of the California electricity industry for which we observe the actual marginal cost and estimate the marginal cost from these data. We compare the actual values of marginal cost with the estimates from semiparametric and nonparametric methods, as well as with the estimates obtained through conventional parametric methods. We show that the semiparametric and nonparametric methods produce marginal cost estimates that very closely approximate the actual. In contrast, the results from conventional parametric methods are significantly biased and provide invalid inference.

“…However, in contrast to a less restrictive nonparametric approach, his analysis was entirely confined to the parametric field, therefore disallowing more flexible interpretations of the relationship. Some recent contributions have also dealt with the quiet life hypothesis and related issues, among which we can highlight the papers by Koetter et al (2012), Delis and Tsionas (2009), Casu and Girardone (2006), and Turk Ariss (2010. Although their objectives are not exactly coincidental with those of Clark (1986), they do neither consider flexible techniques to examine the links between efficiency and market power like we do.…”
