Determinants of profitability of community banks in the USA: a cost-frontier-based decomposition approach
This paper investigates the determinants of the poor profitability of community banks relative to that of large banks in the USA over the period 2001–2017, by decomposing the relative profitability of communit...

Estimation of inefficiency in stochastic frontier models: a Bayesian kernel approach
We propose a kernel-based Bayesian framework for the analysis of stochastic frontiers and efficiency measurement. The primary feature of this framework is that the unknown distribution of inefficiency is appro...

Open AccessEstimation of technical change and price elasticities: a categorical time–varying coefficient approach
We propose a categorical time-varying coefficient translog cost function, where each coefficient is expressed as a nonparametric function of a categorical time variable, thereby allowing each time period to ha...
