Combination of Top-down and Bottom-up DEA models using PCA: A Two-Stage Network DEA with Shared Input and Undesirable Output for Evaluation of the Road Transport Sector
Socio-Economic Planning Sciences. 2023. Vol. 89. Article 101706.
This paper presents a network data envelopment analysis (NDEA) model to assess road transport sector by considering energy and non-energy inputs, shared input, and desirable and undesirable outputs. The sector is considered as a two-stage framework where in stage 1, energy-environmental efficiency is calculated and in stage 2, technical efficiency is estimated. There are two general approaches for evaluation of the network structures using NDEA models: bottom-up and top-down. In the bottom-up approach of this study, a goal programming NDEA (GP-NDEA) model is proposed to calculate the efficiency of the two stages at the same time and then overall efficiency is obtained using the results of the two stages. In the top-down approach, both non-radial SBM-NDEA and RAM-NDEA models are applied to calculate the overall efficiency and then the efficiencies of stage 1 and stage 2 are estimated using the results of the overall efficiency. Three different models GP-NDEA, SBM-NDEA, and RAM-NDEA lead to different results and to obtain the final efficiencies and ranks, principal component analysis (PCA) method is applied. The efficiency generated by different bottom-up and top-down approaches are considered as indicators in PCA, and the final scores for both stages are calculated using PCA. To illustrate the capability of the proposed approach, an actual dataset of road transport sector in provinces of Iran is gathered and the results of the different models are analyzed.

The cryptocurrency market has been considered until recently a market for private, non-portfolio investors, and the research focus has been on volatility. However, gradual institutionalization and creation of ETFs have highlighted new characteristics, including the asymmetry of trade behavior. Our research aims to analyze the relationships between asymmetric risk indicators and the returns of portfolios ...

This work develops a tractable model of price competition in fragmented markets where consumers consider both local and distant varieties, with cross-regional purchases subject to stochastic costs. Global competition and full localization emerge as polar cases; hybrid competition is not merely intermediate and exhibits distinctive features such as an endogenous price ceiling and non-monotonic entry ...

The global wine industry is transforming due to climate change challenges. Glocalization is increasingly relevant in winemaking, where geographical and cultural diversity requires context-specific solutions in the existing sustainability spectrum in viticulture.

The book focuses on the concept of “socialist market, a cornerstone of political economy in Soviet-type societies undergoing economic reforms from the 1950s onward. Encouraged by the success of non-capitalist mixed economies, market reformers (also called 'market socialists') offered the communist ruling elites a remedy for the persistent crises of the planned economy. Besides optimal planning and ...

Scientific collaboration among universities is traditionally studied by counting coauthored papers with different types of partners. Under this approach, the internal mechanisms of collaboration remain hidden and, without additional normalization, the results can be biased.
