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...

Open AccessPredicting recessions with a frontier measure of output gap: an application to Italian economy
Despite the long and great history, developed institutions, and high level of physical and human capital, the Italian economy has been fairly stagnant during the last three decades. In this paper, we merge two...

Aggregate efficiency of industry and its groups: the case of Queensland public hospitals
In this paper, we explore the efficiency of different groups of hospitals in Queensland, Australia, focusing on teaching and non-teaching hospitals, by adapting the most recent developments on statistical anal...

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...

Robust Efficiency Analysis of Public Hospitals in Queensland, Australia
In this study, we utilize various approaches for efficiency analysis to explore the state of efficiency of public hospitals in Queensland, Australia, in the year 2016/17. Besides the traditional nonparametric ...

Forecasting of recessions via dynamic probit for time series: replication and extension of Kauppi and Saikkonen (2008)
In this work, we first replicate the results of the fully parametric dynamic probit model for forecasting US recessions from Kauppi and Saikkonen (Rev Econ Stat 90(4):777–791, 2008) [which is in the spirit of Est...

Aggregation of Individual Efficiency Measures and Productivity Indices
Here, we consider the problem of aggregation of efficiency and productivity indices. We will summarize some of the existing results and will derive new results for aggregation of Hicks-Moorsteen productivity i...

Slack-based directional distance function in the presence of bad outputs: theory and application to Vietnamese banking
In this paper we extend the slack-based directional distance function introduced by Färe and Grosskopf (Eur J Oper Res 200(1):320–322, 2010) to measure efficiency in the presence of bad outputs and illustrate it ...

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...
