Modeling Undesirable Outputs in Data Envelopment Analysis: Various Approaches

Pasupathy, Kalyan Sunder 26 March 2002 (has links)
The general practice in performance and production efficiency measurement has been to ignore additional products of most transformation processes that can be classified as "undesirable outputs" — which are a subset of the output set. Without the inclusion of these factors, the efficiency evaluation becomes a purely technical measure of the system alone, and does not account for the interaction of the system with the surrounding environment and the impact of policy decisions on the system. In addition, there are also technological dependencies arising due to the relationships between the desirable and the undesirable outputs. One of the analytical tools normally used in efficiency evaluation is Data Envelopment Analysis, DEA. In the course of addressing these problems, a decision-maker encounters multiple and contradictory objectives with respect to the output set. This motivates the exploration of new arenas of measurement of efficiency to facilitate policy decisions and address technological relationships. This research presents five modifications of the traditional DEA technique to give a more realistic and comprehensive score of production efficiency considering both, desirable and undesirable outputs. The models address the following problems: (i) technological dependency between desirable and undesirable outputs; (ii) decision-maker's preferences over inputs, desirable outputs and undesirable output performance and finally (iii) conflicting production objectives through a formulation that uses Goal Programming in conjunction with DEA, a concept known as GoDEA. / Master of Science

Stínová cena vzdušných polutantů v českém energetickém sektoru - odhad pomocí vzdálenostní funkce / Shadow Price of Air Pollution Emissions in the Czech energy sector - Estimation from Distance Function

Rečka, Lukáš January 2011 (has links)
This thesis employs a parametric input distance function that incorporates both desirable and undesirable outputs to provide a more complete representation of the production technology. Based on the Shephard (1970) theory of duality, we derive the shadow prices of undesirable outputs in the Czech energy sector on the data over the period 2002 - 2007. The medians of our shadow prices estimates are 8374, 1198, 2805, 6051 and 8549 € per ton of PM, SO2, NOx, CO and VOC, respectively. We decompose shadow prices estimates and test the hypotheses that the marginal abatement cost decline over time; that marginal abatement cost rice with the declining emission level; and that marginal abatement cost rice with declining emission rate. Key Words: shadow prices, distance function, undesirable outputs, marginal abatement cost JEL classification: C61, D24, Q53

Eco-Efficiency and Eco-Productivity Assessments of the States in the United States: A Two-Stage Non-parametric Analysis

Demiral, Elif E., Sağlam, Ümit 01 December 2021 (has links)
This study implements radial and non-radial Data Envelopment Analysis (DEA) models to assess eco-efficiency and eco-productivity of the 50 states in the United States in 2018. The models are based on three inputs (capital stock, employment, and energy consumption), a single desirable output (real gross domestic product) and a single undesirable output variable (CO2 emissions). The radial DEA models reveal that at least 32 states are operated efficiently. Five states perform at the most optimal scale size, whereas 17 states have considerable potential to boost their productive efficiencies by enlarging available resources, and 28 states are overinvested in their input variables given their current output levels. The non-radial DEA models show that, overall, the states’ capital efficiency is very high, whereas energy and emission efficiencies are very low. The states’ eco-productivity is relatively higher than the eco-efficiency levels. In the second stage of the analysis, non-parametric statistical tests and Tobit regressions are conducted for further investigation. According to the non-parametric statistical test, high capital stock, labor force, and energy usage do not affect the states’ productive efficiency. However, states with low carbon dioxide emissions have significantly higher eco-efficiency and eco-productivity levels. The Tobit regression results illustrate that nuclear power and renewable energy consumption significantly affect the states’ relative efficiencies.

Životní postoje a hodnoty vybraných skupin adolescentů / Life attitudes and values of selected groups of adolescents

Matys, Radim January 2016 (has links)
The thesis called "Life attitudes and values of selected groups of adolescents" deals with comparison of changes through longitudinal study in chosen indicators of value orientation and actual life attitudes of adolescents, who are situated in educational institution and being at the same time students of high school preparing themselves for future career. The results are compared with the survey, which was carried out between the years 2009 - 2010. The arrangement of gained data has a character of comparative study, which evaluates an occurrence of certain aspects in respondents' hierarchy of values and maps their shift in a certain period of time. The theoretical part is concerned with attitudes and value orientation, their elements and formations; furthermore it structures a phenomenon of adolescence in general, which is compared in selected indicators with specifically selected groups, which are the subject of the survey. For a better insight into the problematic, the conclusion of the theoretical part specifies an environment of an institutional education and its basic characteristics. The issue is observed from pedagogical, psychological and anthropological point of view. These views offer treatises about possibilities and resources affecting an education in devices for juveniles, whose...

Sustainability Commitment : A study how identity (in)congruence affects organizational commitment.

Hansson, Gustav, Zätterqvist, Daniel January 2020 (has links)
Sustainability has become an important topic in many parts of society. However, companies struggle to translate it into their processes. If an individual values sustainability but is not able to fulfill these values an individual may feel a discrepancy; it may force individuals to feel an (in)congruence in their identity, leading to the question, How does sustainability identity (dis)congruence affect commitment? To answer the question a theoretical model was developed from different nuances of identity theory and organizational commitment. A mixed-method was used to capture the data. The results indicate that dependent on commitment style, the organization may override their personal sustainability identities. Our observations indicate that affective committed individuals choose to justify both personal and organizational actions in order to mitigate value incongruent behaviors. The thesis ends with a chapter of managerial recommendations. / <p><strong>Grade</strong>: Pass with distinction (VG)</p>

考量預期損失之台灣商業銀行效率與生產力分析 / The Efficiency and productivity analysis of banking industry in Taiwan considering expected losses

翁祥容 Unknown Date (has links)
本文以資料包絡分析法衡量2004年第一季至2008年第三季台灣商業銀行之效率與生產力,並以其代表銀行之經營績效。不同於過去文獻之處在於本文以前瞻之觀點(沈中華,2005)求出放款預期損失以衡量放款風險,作為放款過程中的非意欲產出。本文並利用Ray and Desli(1997)架構拆解Malmquist總要素生產力指數,探討銀行績效變動之來源,此外,亦將該拆解結果與Färe et al.(1994)拆解方式比較,發現在技術變動部分有明顯不同。本文並探討影響銀行效率之因素以及檢定不同類型銀行之生產力表現是否有顯著差異。 / The purpose of this paper is to examine the efficiency and productivity change of Taiwan’s banks over 2004Q1-2008Q3 using data envelopment analysis. Unlike the literature of the past, this paper uses the forward-looking viewpoint to derive expected losses from loans to measure the credit risk. In addition, the loan expected loss is thought of as an undesirable output in the estimation of efficiency and productivity. On the other hand, this paper uses a VRS frontier benchmark (Ray and Desli, 1997) to analyze the sources of productivity change. This paper also compares this result with that of Färe et al.(1994)decomposition, and finds that the estimated technical changes of two approaches are significantly different. Further, this paper analyzes the factors influencing banks’ efficiency, and investigates the productivity differences between different ownerships.
