The Darwinian Returns to Scale
SSRN Electronic Journal, 2020 Abstract How does an increase in market size, say due to globalization, affect welfare? We study this question using a model with monopolistic competition, heterogeneous markups, and fixed costs. We characterize changes in welfare and decompose changes in allocative efficiency into three different effects: (1) reallocations across firms ...

Directional congestion in the framework of data envelopment analysis
Journal of Management Science and Engineering, 2020 This study first proposes a definition for directional congestion in certain input and output directions within the framework of data envelopment analysis. Second, two methods from different viewpoints are proposed to estimate the directional congestion.

Increasing Returns to Scale in Carpool Matching: Evidence from _Scoop_
Findings, 2021 Systems that depend on matching often exhibit scale economies, whereby increased participation leads to improved performance for all users. This paper examines the presence of such increasing returns to scale in carpool matching.

On estimating optimal α-returns to scale [PDF]
Journal of the Operational Research Society, 2018 From a theoretical point of view, α -returns to scale is a relevant alternative to traditional DEA models for estimating production technologies under global returns to scale assumptions such as st...

Introduction a method of determining returns to scale in network data envelopment analysis [PDF]
Mathematics and Modeling in Finance, 2022 In the process of evaluating the Decision Making Units, two factors of efficiency and production size can be used. When the production size of a unit is not optimal, its Returns To Scale (RTS) determines that changing the resources in anotherdirection ...

Two-stage Production Systems under Variable Returns to Scale Technology: A DEA Approach [PDF]
Journal of Optimization in Industrial Engineering, 2010 Data envelopment analysis (DEA) is a non-parametric approach for performance analysis of decision making units (DMUs) which uses a set of inputs to produce a set of outputs without the need to consider internal operations of each unit.

Energies, 2023 This study discusses the assessment of OE (operational efficiency) and RTS (returns to scale) over a time horizon. Many previous DEA (Data Envelopment Analysis) studies have discussed how to measure OE/RTS.
