Abstract:Performance measurement encourages Decision Making Units (DMUs) to improve their level of performance by comparing their current financial positions with that of their peers. Data Envelopment Analysis (DEA) is a widely used approach to performance measurement, though it is susceptible when the data is heterogeneous. The main objective of this study is to examine the performance of Mongolian listed companies by combining DEA and a k-medoid clustering method. Clustering facilitates the characterization and patte… Show more
“…The second step, which is called the assignment step, allocates each object to its closest centroid ( Park and Jun, 2009 ). The last stage is the update step where new centroids are assessed for each cluster by computing the average of all observations that part of each cluster ( Bayaraa et al, 2019 ). The algorithm converges when there is no change to the centroids, that is, when assignment of observation points to clusters does not change.…”
Eco-efficiency assessment of municipal solid waste (MSW) suppliers is a useful tool in the transition to a circular economy. Furthermore, it provides evidence of the economic and environmental performance of municipalities that can be used for decision-making and/or elaboration of regulatory policies. In this study, eco-efficiency scores were computed for a sample of 140 Chilean municipalities in the provision of MSW services. In doing so, the stochastic semi-parametric envelopment of data method was applied. It is a novel technique which overcomes the limitations of parametric (stochastic frontier analysis) and non-parametric (data envelopment analysis) methods previously employed to evaluate the eco-efficiency of MSW services. The average eco-efficiency of the 140 assessed municipalities was 0.332 which indicates that they could save 66.8% of their operational costs and recycling the same amount of waste. Moreover, 61.4% of the evaluated municipalities presented an eco-efficiency score which was lower than 0.4, whereas the other municipalities (38.6% of the sample) exhibited an eco-efficiency which raged between 0.4 and 0.80. Hence, none of the municipalities assessed was identified as eco-efficient which, implies that there is room for all municipalities to reduce operational costs in the management of MSW. Population density, tourism and location of the municipality were identified as factors influencing the eco-efficiency of the municipalities in MSW management.

“…Most of DEA models assume the efficient frontier is convex for the purpose on measuring efficiencies. However, non-convex frontiers are existed in the context of reality, and it cannot be solved by traditional methods (Bayaraa et al, 2019). Tone and Tsutsui (2015) introduced the non-convex DEA that regarded as the best model to deal with nonconvex datasets; it is helpful in addressing the problem of imbalances between outbound and inbound investments.…”

Purpose – in light of the Taiwan New Southbound Policy (NSP), this paper aims to evaluate the performance of bilateral cooperation between Taiwan and its economic partner countries in order to have a better understanding of the coherence of reciprocal relations in the past, present and future.
Research methodology – firstly, both individual forecasting models and combining forecasts were employed to predict the future values based on a period of thirty years (1990–2019). Secondly, the paper proposes non-convex DEA to detect non-convex characteristics of datasets where the volume of inputs and outputs were unevenly allocated in past years. Finally, a DEA window was applied to provide efficiency scores for decision-making units (DMUs) across a period of twelve years (2014–2025).
Findings – the results found that the efficiency of seven out of eight DMUs will improve in the coming years. With a stable performance in both scale and efficiency, Singapore is Taiwan’s most successful economic partner, followed by Malaysia. The NSP remained as a vital foreign policy in supporting Taiwan’s bilateral trade and outward foreign direct investment (OFDI).
Research limitations – more inputs and outputs are required in order to reflect the overall performance of the bilateral cooperation between two economies. Furthermore, more extended models are worth further investigation.
Practical implications – the forecasting values of exports and imports can be used in analysing Taiwan economy’s trade deficits. This study provides useful inputs for managers in allocating resources of inbound and outbound values, and reacting rightfully to the uncertain future.
Originality/Value – the paper not only contribute much more than previous ones by evaluating into the relationship between size of scale and efficiency of bilateral economies but also provide advices for policymakers in creating mechanisms that can facilitate the NSP’s sustainable development.
“…A teljesítménymérés általában a szervezet és az alkalmazottak pénzügyi vagy nem pénzügyi szempontú értékelése [47], ami arra ösztönzi a döntéshozó egységeket (DMU-kat), hogy javítsák teljesítményük szintjét azáltal, hogy összehasonlítják jelenlegi pénzügyi helyzetüket társaik helyzetével [4].…”
A teljesítménymérés – a vállalatok pénzügyi-gazdasági teljesítményének mérése – kiemelt jelentőséggel bír mind a vállalatok egyéni teljesítményének megállapításában, mind a vállalatok közötti összehasonlításban. A teljesítmény-mérésnek többféle keretrendszerével és nagyon sok módszerével lehet találkozni a szakirodalomban és a vállalati gyakorlatban is. A globalizáció kiteljesedésével és az új gazdaság kialakulásával még inkább kiemelt szerepet kap e témával való foglalkozás. A cikk célja a teljesítményértékelés szakirodalmának áttekintése és két választott keretrendszer részletesebb ismertetése.
