Applied researchers in the field of efficiency and productivity analysis often need to estimate and make inference about aggregate efficiency, such as industry efficiency or aggregate efficiency of a group of distinct firms within an industry (e.g., public versus private firms, regulated versus unregulated firms, etc.). While there are approaches to obtain point estimates for such important measures, no asymptotic theory has been derived for it. This is the gap in the literature we fill with…

Aggregation of Efficiency and Productivity: From Firm to Sector and Higher Levels
Here we consider various cases where researchers are interested in measuring aggregate efficiency or productivity levels or their changes for a group of decision making units. These could be entire
2 Why Estimate Production ( Technical ) Efficiency ?
Our chapter details a wide variety of approaches used in estimating productivity and efficiency based on methods developed to estimate frontier production using Stochastic Frontier Analysis (SFA) and
Statistical Inference for Aggregation of Malmquist Productivity Indices
The Malmquist Productivity Index (MPI) has gained popularity amongst studies on dynamic change of productivity of decision making units (DMUs). In practice, this index is frequently reported at
The choice of efficiency benchmarking metric in evaluating firm productivity and viability
The Debreu–Farrell measure of technical efficiency is widely used to benchmark firm performance. A limitation of this measure is that it is orientation restricted and evaluates the performance of a
Further Improving Finite Sample Approximation by Central Limit Theorems for Aggregate Efficiency
A simple yet easy to implement method is proposed to further improve the finite sample approximation by central limit theorems for aggregate efficiency. By adopt- ing the correction method in Simar

Implications of Aggregation Uncertainty in DEA
Researchers and practitioners who use Data Envelopment Analysis often want to incorporate several inputs and outputs in their model to consider as much relevant information as possible. However, too

Data envelopment analysis (DEA) and free disposal hull (FDH) estimators are widely used to estimate efficiencies of production units. In applications, both efficiency scores for individual units as
Analyzing Cost Efficient Production Behavior Under Economies of Scope: A Nonparametric Methodology
TLDR
This application shows that the proposed methodology may entail robust conclusions regarding cost-efficiency differences between universities within specific specialization areas, even when using shadow prices to evaluate the different inputs.

Statistical Approaches for Non‐parametric Frontier Models: A Guided Tour
TLDR
This ‘guided tour’ reviews the development of various non-parametric approaches since the early work of Farrell, and remaining challenges and open issues in this challenging arena are described.
Stochastic FDH/DEA estimators for frontier analysis
TLDR
An approach that synthesizes the best features of the two main methods in the estimation of production efficiency, which allows for statistical noise, similar to Stochastic frontier analysis, and allows modelling multiple-inputs-multiple-outputs technologies without imposing parametric assumptions on production relationship.
CAR-DEA: Context-Dependent Assurance Regions in DEA
TLDR
This paper presents a methodology for incorporating multiple sets of AR restrictions, with each reflecting the context for a particular subset of DMUs, and evaluates performance in a manner that more accurately captures the circumstances in which the DMUs operate.
Aggregation of Malmquist productivity indexes
Data Envelopment Analysis with Nonhomogeneous DMUs
TLDR
Data envelopment analysis (DEA) is a methodology for evaluating the relative efficiencies of a set of homogeneous decision-making units (DMUs) in the sense that each uses the same input and output measures (in varying amounts from one DMU to another).
