Open AccessPerformance analysis of hospitals in Australia and its peers: a systematic and critical review
Along with the development of productivity and efficiency analysis techniques, extensive research on the performance of hospitals has been conducted in the last few decades. In this article, we conduct a syste...

Open AccessGeneralized theory for measuring efficiency of individuals and groups
We present a cohesive generalized framework for an aggregation of the Nerlovian profit indicators and of the directional distance functions, frequently used in productivity and efficiency analysis in operation...

Open AccessOn the problem of the purchasing power of money by A. A. Konüs and S. S. Byushgens: translation and commentary
In 1939, Econometrica published an English translation of Konüs (1924). Since then, Konüs (1924 [1939]) has become a classic work on the theory of the cost of living index, inspiring many other studies in the fie...

A generalized flexible functional form for α-returns to scale
This study proposes a new flexible functional form for distance functions. This generalizes the existing functional form of Diewert (1992b) by allowing for α-returns to scale technology and employing the quadrati...

Aggregation in efficiency and productivity analysis: a brief review with new insights and justifications for constant returns to scale
The main goal of this paper is to clarify a few important aspects about the aggregation issues in efficiency and productivity analysis. By doing so we also sketch a brief historical map on how the area of aggr...

Further improvements of finite sample approximation of central limit theorems for envelopment estimators
A simple yet easy to implement method is proposed to further improve the finite sample approximation of the recently developed central limit theorems for aggregates of envelopment estimators. Focusing on the s...

Is newer always better? A reinvestigation of productivity dynamics using updated PWT data
Understanding the drivers of productivity remains one of the most sought after phenomena in economics. The ability to create produce more from less resources is undoubtedly appealing. Using recently updated Pe...

Quadratic-mean-of-order-r indexes of output, input and productivity
This paper deals with the quadratic-mean-of-order-r indexes of output, input and productivity. Each index is a family of indexes that unify many of the existing indexes, including the most popular ones. We show t...

Sequential data envelopment analysis
We consider a new class of Data Envelopment Analysis (DEA) modeling, which we call ‘sequential DEA’. This new approach is a relatively simple generalization of the standard and popular in practice DEA. It allo...

On aggregation of multi-factor productivity indexes
The goal of this paper is to investigate the question of the importance of aggregation of the Paasche and Laspeyres versions of the Malmquist quantity and productivity indexes from both theoretical and empiric...

Aggregation of Outputs and Inputs for DEA Analysis of Hospital Efficiency: Economics, Operations Research and Data Science Perspectives
Data envelopment analysis (DEA) has been widely recognised as a powerful tool for performance analysis over the last four decades. The application of DEA in empirical works, however, has become more challengin...

Nonparametric least squares methods for stochastic frontier models
When analyzing productivity and efficiency of firms, stochastic frontier models are very attractive because they allow, as in typical regression models, to introduce some noise in the Data Generating Process ....

How relevant is the choice of risk management control variable to non-parametric bank profit efficiency analysis? The case of South Korean banks
Adopting a profit-based approach to the estimation of the efficiency of South Korean banks over the 2007Q3 to 2011Q2 period, we systematically analyse, within a non-parametric DEA analysis, how the choice of r...

Categorical data in local maximum likelihood: theory and applications to productivity analysis
In this paper we consider estimation of models popular in efficiency and productivity analysis (such as the stochastic frontier model, truncated regression model, etc.) via the local maximum likelihood method...

Pricing of decision-making units under non-constant returns to scale
In this article, we revisit a recent work on pricing decision-making units by Färe et al (2013) and extend it to allow for non-constant returns to scale technologies.

Scale efficiency and homotheticity: equivalence of primal and dual measures
We address the issue of equivalence of primal and dual measures of scale efficiency in general production theory framework. We find that particular types of homotheticity of technologies, which we refer to her...

Is foreign-bank efficiency in financial centers driven by home or host country characteristics?
This paper investigates whether home or host country factors can explain differences in technical efficiency among foreign banks operating in the Luxembourg financial center. We first address heterogeneity acr...
