The purpose of this study is to determine whether the Data Envelopment Analysis (DEA) can be applied to Chief Executive Officer (CEO) remuneration of companies listed on the Johannesburg Stock Exchange (JSE) by defining inputs in terms of remuneration factors and outputs in terms of business factors in order to establish a benchmark for CEO remuneration. An exploratory study is conducted, using cross-sectional data from a secondary source. The sample consists of 221 companies listed on the JSE that disclosed their financial and non-financial information during 2010. The DEA was performed to estimate the relative technical efficiency of CEOs to convert their remuneration into company performance indicators. Base Pay, Perquisites and Pension, Annual Bonus Plans and Long-term Incentives were used as the inputs to the DEA model and company performance and size, measured by Return on Equity (ROE) and Total Assets respectively, were used as the outputs to the model. The empirical results prove that the DEA can be successfully applied as a benchmarking model for CEO remuneration that incorporates multiple inputs and outputs and establishes benchmarks and potential improvements for overpaid, inefficient CEOs. The CEOs from 80 of the 221 companies included in the sample emerged as the benchmark CEOs and formed the efficiency frontier against which inefficient CEOs were compared in order to determine the potential improvements for these CEOs. From a research perspective, this study contributes to the advancement of CEO remuneration research by introducing an alternative model by which CEO remuneration can be analysed. Future studies can analyse CEO remuneration by using other variables or time series data in the DEA model or combine the DEA with other methods like the regression analysis to perform more comprehensive investigations. From a practical perspective, the DEA can be used to establish a benchmark for CEO remuneration. Remuneration committees can use the results of the DEA as a guide to determine acceptable remuneration levels and decrease the pay gap between CEOs and the average worker. The originality of this study lies in the fact that it is the first South African study that used the DEA instead of the regression analysis to analyse CEO remuneration of companies listed on the JSE. This study also disaggregated Total CEO Remuneration into Base Pay, Perquisites and Pension, Annual Bonus Plans and Long-term Incentives to provide more accurate benchmark information. In addition, this is the first study that established benchmark CEO remuneration levels and suggested improvements to the remuneration package structure of overpaid, under-performing CEOs of companies listed on the JSE. / Thesis (MCom (Management Accountancy))--North-West University, Potchefstroom Campus, 2013.

Productivity and efficiency are the tools used in managing performance. This study researches and implements best practices that lead to best performance. A customer quality defined standard has to be created by benchmarking the Information Technology Service Regions which may be used to help decision-makers or management make informed decisions about (1) the effectiveness of service systems, (2) managing the performance of Information Technology Service Regions. Waiting lines or queues are an everyday occurrence and may take the form of customers waiting in a restaurant to be serviced or telephone calls waiting to be answered. The model of waiting lines is used to help managers evaluate the effectiveness of service systems. It determines precisely the optimal number of employees that must work at the centralised service desk. A Data Envelopment Analysis (DEA) methodology is used as a benchmarking tool to locate a frontier which is then used to evaluate the efficiency of each of the organizational units responsible for observed output and input quantities. The inefficient units can learn from the best practice frontier situated along the frontier line. / Thesis (M.Sc. (Computer Science))--North-West University, Vaal Triangle Campus, 2009.

銀行保險對我國壽險公司日益重要，在2003年時新契約保費收入高達25％都是由其所貢獻。但造成銀行保險對我國壽險公司日益重要的因素，究竟是因其對我國壽險公司經營效率產生正面之影響，抑或大家只是一窩蜂地搶進？因此，本研究將透過實證分析，探討銀行保險對我國壽險公司經營績效之影響。 本研究首先採用資料包絡分析法進行效率分析。之後，再以Tobit迴歸分析影響人壽險公司之經營效率因素為何。 經營效率上，我國整體壽險公司之總生產效率沒有達到該有的一半。進一步分析總生產效率，發現配置效率比技術效率來的無效率。技術效率則呈現上升的趨勢。如進一步分析其上升之因素，發現是純技術效率與規模效率上升所造成。 在Tobit迴歸分析指出銀行保險確實對壽險公司之經營效率有所助益。產品集中程度與經營效率無顯著關係。市佔率與總生產效率、技術效率以及規模效率呈現負相關，可見我國壽險公司會因其市佔率高而導致其提升經營效率之誘因下降。外商公司在規模效率與配置效率低於本國公司，原因在於對我國市場之不熟悉。是否為金控公司子公司，因限於時間因素，對我國壽險公司之經營效率影響尚不明顯。最後，東南亞金融風暴、地雷股事件等造成市場利率走低，故投資資產比率與技術效率呈負向關係。另外，總資產規模與各項效率呈現顯著正相關，代表規模愈大的公司愈能有效率地經營。 / Bancassurance, which caused new policy’s premium to reach to 25% in 2003, has become more and more important to the life insurance industry in Taiwan. But what made it so significant, its positive effect upon increasing the operating efficiency of the life insurance industry in Taiwan, or the irrational people who just swarming into it? Thus, this research tests how bancassurance influence the life insurance industry in Taiwan. This study uses Data Envelopment Analysis to measure the operating efficiency, and Tobit regression to test what were the facts that influenced operating efficiency of life insurance industry. As for the life insurance industry in Taiwan, not even half of the overall efficiency was reached to what it should be. To analyze further to overall efficiency would come out the conclusion that allocative efficiency was less efficient than technical efficiency while technical efficiency was trending up. The rising of pure technical efficiency and scale efficiency was found out to be the reason of ascension after profoundly analysis. Tobit regression supports that bancassurance is positive related to operating efficiency of life insurance industry. The product fucus or diversification is not related to operating efficiency. Market share has negative relationship with overall efficiency, technical efficiency and scale efficiency, which indicate that the inducement of increasing operating efficiency of the life insurance industry could be lowered due to their high market share. Scale efficiency and allocative efficiency is lower in foreign companies than in domestic companies for that foreign companies are unfamiliar with the market of Taiwan. There is no relationship between subsidiaries of holding company with operating efficiency yet because of the time-limited. At last, due to the financial storm in South-east Asia, the event of accounting fraud and etc, the market interest rate was trending low, and then made the ratio of investment assets to the total assets to be negative related to technical efficiency. Furthermore, the positive relationship between scale and efficiency represents that the larger the scale of a company is, the more efficient it can be in running business.

美國全國保險監理協會為了確保產險公司的清償能力，及當產險公司資本比率低於某一定比率時監理機關可以實施某些管制措施，而於1994於產險業實施風險基礎資本額(RBC)制度。但由於提供金融服務的功能性障礙逐漸降低，以及產險產業的競爭日趨激烈。因此，產險公司必須在清償能力和效率目標間找出一個平衡點，在符合成本效率的情況之下持有適切的非風險性資產並提高股東權益比率。因此，本研究主要在探討RBC之實施是否會對美國產險公司之成本效率帶來影響。 本研究以美國產險業的RBC實施年度，也就是1994年為分界，檢測372家美國產險公司在1990至1998年間成本效率之趨勢變化。 研究結果指出，在RBC實施之後，產險公司的成本效率及配置效率都有明顯的下降趨勢，但技術效率卻沒有太大的變動趨勢。此外研究結果也顯示產品集中程度與成本效率及配置效率呈顯著負向關係。市佔率與成本效率、技術效率以及配置效率呈現負相關。股份公司在成本效率與配置效率高於相互公司。另外，總資產規模與各項效率呈現顯著正相關，代表規模愈大的公司愈能有效率地經營。研究結論顯示RBC實施之後，產險公司為因應RBC之要求，可能會調整風險性之投資，但也導致產險業者成本效率及配置效率之降低。 / The risk-based capital (RBC) requirements developed by the National Association of Insurance Commissioners (NAIC) were intended to raise the safety net for insurers and to provide regulators with the authority to intervene when capital falls below a minimum standard of capital adequacy that is related to risk. Since the less functional barrier of financial service and the greater competition among the property-liability insurers which forced the property-liability insurers to find a balance between solvency and efficiency so that the insurers can have enough cost efficiency and keep maintaining adequate non risk assets as well as rising shareholders’ equity. Therefore, the purpose of this research is to examine the cost efficiency change after property-liability insurers applied RBC standards. To do this, we examine 372 property-liability insurers’ data from 1990-1998 and compare the efficiency change before and after 1994, the RBC standards effective year. This study applies Data Envelopment Analysis and uses the grand frontier approach to measure the cost, allocative and technical efficiency. The statistical results reveal that after applied RBC standards cost and allocative efficiency had significant decline, but no change in technical efficiency. The Tobit regression statistical results indicate that the product concentration has a negative effect on cost efficiency and allocative efficiency; and the market share has a negative relationship with cost efficiency, technical efficiency and allocative efficiency. Cost efficiency and allocative efficiency of incorporate companies are higher than that of mutual companies. Furthermore, the positive relationship between the firm size and efficiency suggested that the larger the size the better efficiency. Overall results imply property-liability insurers may be forced to adjust their investments risk, however, such adjustment might be contributed to less cost and allocative efficiency after applied to RBC standards requirements.

Η παρούσα διπλωματική εργασία μελετά την επίδραση του κόστους περιστολής της ρύπανσης σε συγκεκριμένους κλάδους της ελληνικής βιομηχανίας, την χρονική περίοδο 1993-2006, στην παραγωγικότητά τους. Από θεωρητικής πλευράς εστιάζει στις αντικρουόμενες προσεγγίσεις της win-win υπόθεσης του Porter (1990,1991) και των Porter and Van der Linde (1995) με την νεοκλασική θεωρία, που είχε ως κύριους εκφραστές τους Jaffe και Palmer (1995,1997). Η μεθοδολογική προσέγγιση που ακολουθείται στηρίζεται στην μη παραμετρική μέθοδο της DEA με στόχο την εκτίμηση δεικτών παραγωγικότητας Malmquist (Malmquist Total Factor Productivity Index). Για την μελέτη της επίδρασης του κόστους περιστολής της ρύπανσης σε κλάδους της Ελληνικής βιομηχανίας ακολουθήθηκε η μεθοδολογία που αναπτύχθηκε απο τους Aiken et al., (2009) για τον διαχωρισμό και υπολογισμό μεταξύ regulated-unregulated συναρτήσεων ορίων παραγωγής. Στην εμπειρική εφαρμογή της μελέτης χρησιμοποιήθηκαν δεδομένα απο την ετήσια έρευνα βιομηχανίας της Ελληνικής Στατιστικής Υπηρεσίας σε 23 βιομηχανικούς κλάδους, σύμφωνα με την κωδικοποίηση ΣΤΑΚΟΔ 2003, και παρατηρείται συνολικά επουσιώδης αρνητική επίδραση τους κόστους περιστολής των ρύπων στην παραγωγικότητα. Πιο συγκεκριμένα, κλάδοι με υψηλή ενεργειακή ένταση φαίνεται να εμφανίζουν μηδενική επίδραση των περιβαλλοντικών δαπανών στην παραγωγικότητά τους με μοναδική εξαίρεση του κλάδου των ορυκτών-μετάλλων. / The passage of environmental regulation has been associated with a potential negative or positive effect on firm’s productivity. The present study studies the effect of pollution abatement activities on the productive efficiency of polluting industries in Greece over the period 1993-2006. A methodological approach based on Aiken et al., (2009) study have been developed in order to specify regulated and unregulated production frontiers and to determine the possible link between pollution abatement activities and sector’s productivity growth. Data derived form the Hellenic Statistical Authority has been used in order to estimate the possible association. Our results indicate, for the majority of the manufacturing industries, that increased rates of productivity growth have been simultaneously experienced with decreased rates of pollution abatement.

Os benefícios que a Tecnologia da Informação (TI) tem trazido à sociedade e às organizações vem aumentado ao longo do tempo. A TI tem se desenvolvido com uma rapidez muito grande, prometendo ganhos de eficiência e aumentos na produtividade das empresas. Nos últimos anos, inúmeras organizações têm investido altas quantias em TI, independentemente do setor em que atuam. Dentro deste contexto, observa-se que o setor bancário tem se destacado, pois os recursos destinados para investimentos em TI crescem em ritmo acelerado. Entretanto, a falta de boas medidas quantitativas para mensurar o impacto destes investimentos na produtividade dificulta sua comprovação. Desta forma, fazem-se necessários estudos que apliquem métodos de análise temporal dos investimentos em TI, já que este tipo de investimento não apresenta resultado imediato. Buscando sanar esta lacuna, este trabalho utilizou a metodologia Análise Envoltória de Dados (DEA), que visa analisar eficiência de instituições homogêneas de forma relativa. A partir desta técnica, buscou-se analisar o efeito das variações dos investimentos em TI de um ano para outro nas variações da eficiência relativa dessas instituições em até quatro períodos seguintes ao investimento, visando identificar uma possível regularidade cíclica. Utilizou-se um banco de dados contendo treze anos de informações contábeis de 260 bancos em atuação no Brasil. Dentre as principais conclusões obtidas a partir do teste de diferenças de média, destaca-se que os aumentos dos Investimentos em TI de um ano para outro não são traduzidos em aumentos de eficiência no ano seguinte à sua realização, em nenhum dos três momentos de conversão estudados. Analisadas as defasagens temporais das variações das eficiências em dois, três e quatro anos após o incremento dos Investimentos em TI, percebeu-se que no momento de Conversão II, este foi traduzido em eficiência ao transformar Ativos em Receitas Líquidas. Já na Conversão Global, o período para reverter de forma direta, a variação dos investimentos em TI em variação de eficiência relativa, é de dois anos. A Conversão I, que representa a capacidade do banco ser competitivo, ao transformar Despesas em Ativos, não apresentou significância nos intervalos de tempo analisados no estudo. / The benefits brought by Information Technology (IT) to the society and to organizations have increased over time. IT has been developed very quickly, promising companies’ increases in efficiency and productivity. Lately, many organizations have invested great sums in IT, regardless of the sector in which they operate. Within this context, the banking sector has gain a prominent position, since its resources in IT investments grow at an accelerated rhythm. However, the lack of good quantitative measures to mensurate the impact of these investments on productivity complicates its evidence. Thus, studies that apply temporal analysis methods of IT investments become necessary, since this type of investment does not show immediate results. Trying to heal this gap, this study has used the Data Envelopment Analysis (DEA) methodology which aims to analyze the efficiency of homogeneous institutions in a relative way. With this technique, the effect of the variation in IT spending from one year to another in the variations of relative efficiency of these institutions has been analyzed up to four periods following the investment, in order to identify a possible cyclical regularity. A database containing thirteen years of accounting information from 260 banks in operation in Brazil was used. Among the main results from the mean differences test, deserves attention the fact that in none of the three stages of conversion studied increases in IT investments from one year to another are translated into increases in efficiency in the years following its implementation. Analyzed the temporal discrepancies of the changes in efficiencies in two, three and four years after the increase of IT investments, it was noticed that at the time of Conversion II, this has been translated into efficiency to transform Assets in Revenues. However, in the Global Conversion the period to directly reverse the variation in IT investments in variation of relative efficiency is two years. Representing the bank's ability to be competitive, Conversion I showed no significance when Expenses were turns into Assets in the time intervals analyzed in this study.

Investing in innovativeness, i.e.the great ability to promote innovation has been pointed as the way for the companies to achieve success in highly competitive markets. In the hospital business, enterprises have invested in innovation in order to enhance both the quality of their health services, as well the efficiency. However, given the multiple meanings of the terms innovation and innovativeness in the literature, there are still questions about the actual contributions of these factors for the enterprises performance. Especially in segments whose innovative dynamics is distinguished from others by their specific aspects, as in the hospital business. Thus this research aimed to clarify the influence of innovativeness in hospital performance. Therefore innovativeness was defined as a measure of the companys ability or propensity to innovate, both perceived by the organizations internal culture and the way of acting in the marketplace. This operation was achieved by compiling variables from two constructs of innovativeness: Organizational Innovativeness (IO) and Perceived Firm Innovativeness (PFI). Operational performance was defined as a measure of the efficiency, with which a private hospital enterprise uses the resources available to provide services, comparing to other private hospitals. By a comprehensive literature review, we identified non-financial variables often used in hospital researches, both domestic and international. This operation was achieved by using Data Envelopment Analysis (DEA) mathematical model. Based on a sample of 17 private hospitals, we found that the innovativeness perceived by hospital managers has an inverse relationship with the operational technical efficiency of hospital enterprises / A inovação é considerada atualmente um dos principais fatores que contribuem para a diferenciação competitiva e para a melhoria do desempenho organizacional. Investir na capacidade ampla de promover inovações, a inovatividade, tem sido destacada como o caminho para que as empresas alcancem o sucesso em mercados marcados pela grande competitividade. No segmento hospitalar, os empreendimentos têm investido em inovação como forma de promover melhorias que tanto aumentem a qualidade de seus serviços à saúde, quanto contribuam para a melhoria de sua eficiência. Todavia, diante da diversidade com que os termos inovação e inovatividade são utilizados na literatura, ainda persistem questionamentos quanto às reais contribuições destes fatores para o desempenho dos empreendimentos. Principalmente em segmentos cuja dinâmica inovativa se distingue dos demais por suas especificidades, como no segmento hospitalar. Sendo assim, esta pesquisa procurou contribuir para o esclarecimento da influência da inovatividade no desempenho hospitalar. Para tanto, a inovatividade foi definida como uma medida da capacidade ou propensão da empresa inovar, tanto percebida pela cultura interna da organização quanto por sua forma de atuar no mercado. Sua operacionalização foi possível pela compilação de variáveis provenientes de dois construtos de inovatividade: Inovatividade Organizacional (IO) e Inovatividade Percebida da Firma (PFI). O desempenho operacional foi definido como uma medida da eficiência com que o empreendimento hospital privado utiliza-se dos recursos de que dispõe para prestar serviços, comparativamente à outros hospitais privados. Através de uma revisão ampla de literatura, foram identificadas variáveis não financeiras frequentemente utilizadas nas pesquisas hospitalares, tanto nacionais quanto internacionais. Sua operacionalização se deu através do modelo matemático Data Envelopment Analysis (DEA). Com base em uma amostra de 17 hospitais privados, constatou-se que a inovatividade percebida pelos gestores hospitalares possui relação inversa com a eficiência técnica operacional desses empreendimentos.
