A Simultaneous Stochastic Frontier Model with Dependent Error Components and Dependent Composite Errors: An Application to Chinese Banking Industry

Abstract: The paper develops a simultaneous equations stochastic frontier model (SFM) with dependent random noise and inefficiency components of individual equations as well as allowing dependence across all equations of the model using copula functions. First, feasibility of our developed model was verified via two simulation studies. Then the model was applied to assess cost efficiency and market power of the banking industry of China using a panel data of 37 banks covering the period 2013–2018. Results confirmed that… Show more

“…Moreover, the issues regarding random or measurement errors are especially prominent for productivity analysis at the macro level [44]. Instead, SFA allows the separation of inefficiency from random shocks or measurement errors, thus providing a more accurate estimate of efficiency [18,45]. Given this advantage, SFA has been applied in various studies to analyze agricultural productivity and its components, such as by Benedetti et al [46], Adetutu and Ajayi [18], and Gong [23].…”

“…Corbae and D'erasmo (2013) identified numerous crucial variables, such as interest rates, loan default rates, and bank capital adequacy ratios, that substantially affect the business's behavior and outcomes. In a study, the author applied a stochastic frontier model to a sample of Chinese banks and found evidence of substantial technical and allocative inefficiencies and substantial variability and reliance between banks (Liu et al, 2020). In another study on Chine's banking industry, the dynamic modeling approach was used to evaluate the influence of external factors such as macroeconomic conditions, regulatory policies, market competition, and technological innovation, and their feedback loops over time (Li et al, 2021).…”

“…To answer these questions, we performed a simulation experiment. Following the simulation experiments of Wei et al [44], Liu et al [45] and Zhu et al [46], we randomly drew datasets from a copula-based stochastic frontier model with heterogeneity. The simulated process of this experiment can be illustrated as follows:…”
