This article creates a conceptual model, called network system, to represent the Brazilian banking production based on its internal operational processes. The first, intermediation process, measures bank's efficiency in extending loans from available resources. second, revenue earning profit, mainly granted. We adopt two-stage DEA model. In first stage, relational model both system scores and t...

this study uses the data envelopment analysis (dea) to assess the progress/regression of decision-making units (dmus) having a two-stage structure‎. ‎the progress/regression of these dmu can be assessed in the first stage‎, ‎the second stage‎, ‎and the whole system‎. ‎in the first stage‎, ‎the progress/regression of bank branches in collecting resources and in the second stage their progress/re...

The purpose of this paper is to evaluate the performance of a sample of natural resources exchange traded funds (ETFs) by applying a two-stage procedure. In the first stage, the generalized proportional distance function (GPDF) in the data envelopment analysis (DEA) context is used for the first time to measure the relative efficiency of sectoral ETFs. In the second stage, a Tobit model is empl...

• Subsampling bootstrap procedure for DEA estimator is extended to network structure The subsampling proposed also considers undesirable factors Evidence on the performance of obtained through Monte Carlo experiments method applied evaluation railways in OECD considering noise pollution problem Data Envelopment Analysis (DEA), provides an empirical estimation production frontier, based observed...

This paper processes a combined method, based on VIKOR and Data Envelopment Analysis (DEA) to select the units with most efficiency. We utilize the VIKOR as compromise solution method. This research is a two-stage model designed to fully rank the alternatives, where each alternative has multiple inputs and outputs. The problem involves BELIEF parameters in the solution procedure. First, the alt...

The field of productive efficiency analysis is currently divided between two main paradigms: the deterministic, nonparametric Data Envelopment Analysis (DEA) and the parametric Stochastic Frontier Analysis (SFA). This paper examines an encompassing semiparametric frontier model that combines the DEA-type nonparametric frontier, which satisfies monotonicity and concavity, with the SFA-style stoc...
