The existing cross-efficiency evaluation methods under network structures are all limited to two basic network systems: series and parallel. Based on the directional distance function (DDF), we firstly propose the cross-efficiency evaluation method for a parallel two-stage system, which consists...

The paper analyzes properties of a large class of ``path-based'' Data Envelopment Analysis models through a unifying general scheme, which includes as standard the well-known oriented radial models, the hyperbolic distance measure model, and the directional distance measure models. The scheme...

This article has examined the operating cost inefficiencies and economies of scale of Tunisian public water services. We have examined the stochastic frontier model and the fixed effects model. Thus, as formulated, the inefficiency term remains in the model and the fixed effect is intended only...

This paper explore the role of institutions to enhance the productivity growth across countries using a two stage Double Bootstrap Data Envelopment Analysis (DEA). The productivity growth is calculated on the basis of Malmquist productivity index. It also explores the sources of productivity...

COVID-19 has stimulated additional research interest on economic sustainability and ESG in both academia and industry. This study adopts a DEA approach to examine the efficiency of achieving ESG targets and their relationships with financial performance. Using MSCI ESG data from 2015-2019 on...

In goals-based wealth management (GBWM), an investor looks to maximize the probabilities of attaining each of n goals over time. Because the goals are in competition for potentially limited financial resources, their relative importance must be specified, which we do by assigning utility weights...

When there are efficiency spillovers, we can use a spatial autoregressive stochastic frontier model to estimate total (spillover-corrected) efficiencies. Glass et al. (2016) ( Journal of Econometrics ) provide a formula for total efficiency in this context, which is an approximation. We provide...

It is well known that when the empirical skewness of the OLS residuals display the opposite sign of what is expected from the stochastic frontier model, maximum likelihood estimation will be equivalent to OLS and no inefficiency will be recovered. A variety of approaches to operate in this...
