Essays on Organizational Form and Efficiency in the Takaful Insurance IndustryAl-Amri, Khalid Said Humaid January 2013 (has links)
Many studies have focused on the insurance industry in the US and other developed countries. Few studies have investigated the efficiency and organizational form in developing countries. This is particularly true for the Takaful insurance industry. Takaful insurance is mutual insurance based on Islamic principles. The rapid growth of Takaful insurers in many countries around the world and their long existence make it important to examine them. Chapter 1 discusses the history and the practice of insurance during the time of ancient Arabs tribes. I discuss the conduct of the Holy Prophet (SAW) relating to insurance practice. I also briefly outlines the development of Islamic insurance in the fourteenth to the seventh centuries, nineteenth century, and the development in the twentieth century. Chapter 2 investigates economies of scope and agency problems for Takaful insurance companies operating in 19 countries. I test the conglomeration hypothesis, which holds that firms can optimize by diversifying across businesses, versus the strategic focus hypothesis, which holds that firms improve by focusing on core businesses. More specifically, I analyze whether it is advantageous for insurers to offer both property-liability insurance and family insurance (life insurance), or to specialize in one major industry segment. I also test for agency problems, which imply that firms must motivate the agent to ensure compliance with the principal's wealth maximization objectives. That is, I analyze whether it is advantageous for insurers to operate under a Mudharaba (profit sharing) model or operate under a Wakala (fee based) model. I estimate cost efficiency utilizing data envelopment analysis (DEA). Then, I test for scope economies and agency problems by regressing efficiency scores on control variables and indicators for strategic focus and the operating model. The results show that the Wakala operating model is cost inefficient and focused Takaful insurers are associated with higher cost efficiency. Chapter 3 investigates the relationship between insolvency risk and efficiency for Takaful insurers. I measure the insolvency risk by computing the z-score which measure distance to default. I calculate the efficiency scores using Data Envelopment Analysis (DEA). I find that efficient firms have a higher distance to default. I also find that firms which operate in multiple lines are penalized for diversification by being more likely to become insolvent. In addition, I show that investing in sukkuk and real-estate increase the insolvency risk. Chapter 4 analyzes the coexistence of Takaful and conventional insurance. I analyze the efficiency of different organizational forms in 13 countries. Technical, allocative, cost, and revenue frontiers were estimated using data envelopment analysis. I test the expense preference hypothesis and efficient structure hypothesis. I find evidence for the efficient structure hypothesis which claims that the two organizational forms serve different market segments due to differences in managerial discretion and access to capital. I also find evidence for the expense preference hypothesis which states that mutual insurers are less cost efficient than stock insurers due to unresolved agency conflicts (e.g., higher bonus consumption by mutual managers). The results provide insight into the competitiveness of conventional and Takaful insurers from different countries. Finally, chapter 5 concludes the main results of the study. / Business Administration/Risk Management and Insurance

Persistent Inefficiency in the Higher Education SectorGralka, Sabine 04 October 2016 (has links) (PDF)
Evaluations of the Higher Education Sector are receiving increased attention, due to the rising expenditures and the absence of efficiency enhancing market pressure. To what extent universities are able to eliminate inefficiency is a question that has only partially been answered. This paper argues that heterogeneity among universities as well as persistent inefficiency hinder the institutions to achieve full efficiency - at least in the short run. Two standard and one novel specification of the Stochastic Frontier Analysis are applied to a new, comprehensive set of panel data to show how the standard efficiency evaluation changes when both aspects are taken into account. It is the first time that the idea of persistent inefficiency is considered in the analysis of the German Higher Education Sector. The comparison reveals that the disregard of heterogeneity distorts the estimation results towards lower efficiency values. The newly introduced specification improves the accuracy of the heterogeneity assumption and exposes that inefficiency tends to be long term and persistent rather than short term and residual. This implies that increasing efficiency requires a comprehensive change of the university structure.

The impact of financial liberalisation on the efficiency of Malaysian banks : an empirical analysis using frontier measurementsTamjis, Azrie January 2014 (has links)
The Asian financial crisis in 1997 98 left a severe impact on Malaysia s economy and banking system. This has forced the Malaysian government to undertake financial restructuring initiatives to restore market and public confidence, and to meet the ongoing challenges associated with market structure, financial innovation and globalisation. Therefore, Bank Negara Malaysia (BNM) introduced a ten-year Financial Sector Master Plan (FSMP) to strengthen domestic banks and the regulatory structure, and to promote the banks efficiency by stimulating a competitive banking industry through financial liberalisation. The crisis for banks in Malaysia and the region has been extensively studied in the past (Sufian, 2010). However, empirical studies of the post-crisis period, and the implementation of the FSMP, remain limited. Hence, a data set of all banks in Malaysia, which covers the period 2000 2011, was employed to examine the effect of the FSMP s initiatives on Malaysian banks efficiency between 2000 and 2011. To measure this efficiency, this study employs both parametric and nonparametric models: namely, stochastic frontier analysis (SFA) and data envelopment analysis (DEA). Economic functions such as, cost-, standard profit- and alternative profit-efficiency were used in a 1-stage SFA model, which includes control variables (e.g. capital adequacy, asset quality and liquidity) and environmental variables (e.g. ownership, size, specialisation, deregulation periods and market structure) in the model specifications. In addition, this study employs SFA as the main measurement method, while the DEA model was used to cross-check consistency (Resti, 1997; Bauer et al., 1998). Both SFA and DEA demonstrated that, in most cases, the consistency was moderate. The level of cost efficiency of Malaysian banks worsened over the years 2000 2011, with average cost efficiency during this period was at 76.5%. Despite the various liberalisation measures introduced to the banking industry particularly during the three phases of the FSMP; 2000 2003; 2004 2007; 2008 2011 cost efficiency trended downward, due to the effects of consolidation by domestic banks, deregulation of interest rates, the introduction of foreign Islamic banks, and the global credit crisis. Banks in Malaysia were forced to adjust their inputs and outputs to the rapid changes in the banking industry, which might have made a negative impact on cost efficiency. On the other hand, the banks demonstrated a steadily increasing profit efficiency trend, which fluctuated with the introduction of interest rate liberalisation (early second phase of the FSMP (i.e. 2004)) and during the global credit crisis (early third phase of the FSMP (i.e. 2008)). The average profit efficiency for 2000 2011 was 93.3%. The profit efficiency exhibited an increasing trend in the first (2000-2003) and second (2004-2007) phases of the FSMP, suggesting that the effect of consolidation by domestic banks had resulted in higher market concentration and greater market power among the remaining banks. However, the profit efficiency average scores fell in 2004, 2008 and 2011. This is attributed to the deregulation of interest rates, the deleveraging of the inflow of foreign funds, and the rapid increase in policy interest rates. At a more granular level, domestic banks were found to be more cost efficient, but marginally less profit efficient, when compared to foreign banks. In terms of bank specialisation, conventional banks were more cost- and profit-efficient than Islamic banks. With regard to economies of scale, the majority of Malaysian banks revealed scale economies, illustrated by a U-shape, with medium-sized banks being more scale efficient than small and large banks. These results suggest that, to enhance Malaysian banks efficiency, the government must maintain competitive pressure on the large domestic banks that were consolidated during the first phase of the FSMP (2000-2003). Policymakers may want to further open up banking markets, improve risk management and governance, encourage financial innovation, and support expansion of smaller banks. The implementation of deregulation initiatives during periods of uncertainty (e.g. the global credit crisis) have also resulted in decreasing trend of cost and profit efficiency. Hence, monitoring initiatives, using tools such as frontier measurement is important for regulator s macro- and micro-prudential surveillance.

The impact of the credit crunch on the cost and profit efficiency of the banks: an international comparisonBabin, Adrian January 2011 (has links)
This thesis documents, using an unbalanced panel of Top 1000 World banks with observations for 2005 - 2009, three main aspects related to cost and profit efficiency in banking. First, it established that there is no correlation between a bank's rank in the Top and its rank given by the efficiency scores. However, the size of the banks plays a positive role on the cost efficiency of the institution, big banks having higher cost efficiencies than small banks. Conversely, the profit efficiency is equal across different sizes. Second, it verified that for 2005 - 2009 there is no evidence that banks from the developed countries are more efficient than banks from emerging economies. This finding is further supported by the third aspect, which shows that banks originating in the developed economies, with large exposures to more sophisticated banking products, have been hit the hardest by the financial crisis. However the banks managed to shrink their cost inefficiency while losing efficiency on the revenue side. The post crisis, 2009, proved to be a year in which banks across countries and regions converged in terms of efficiency and plateaued at about 10% and 25% for cost and profit inefficiency respectively.

Three essays on rebound effectsAdetutu, Morakinyo O. January 2015 (has links)
This thesis investigates three major aspects of energy consumption rebound effects (RE) in three papers. More specifically, the issues addressed are (i) the magnitude of economy-wide rebound effect (ii) the role of energy policy instruments in mitigating it and (iii) its channels of impact. The research begins with the estimation of cross-country economy-wide rebound effects for a panel of 55 countries over the period 1980 to 2010. A two-stage approach is utilized in which energy efficiency is first estimated from a stochastic input distance frontier (SIDF). The estimated energy efficiency is then used in a second stage dynamic panel model to derive short-run and long-run RE for an array of developing and developed countries. The cross-country point estimates indicate substantial RE magnitudes across sampled countries during the period under consideration, although a positive and encouraging finding is the declining RE trend across most of the sampled countries during the study period. The second paper contains an RE benchmark for 19 EU countries, as well as an investigation of the effects of two energy policy instruments (energy taxes and ener-gy R&D) on RE performance over the period 1995 to 2010. The results indicate that RE performance improved over the sample period, reinforcing the results from paper one. In addition, there is also some evidence suggesting that binding market-based instruments such as energy taxes have been more effective in restricting RE than in-direct instruments such as energy R&D during the period under consideration. This is consistent across both estimated model specifications. An important observation from the first essay is the slightly larger average RE across the non-OECD countries. For this reason, the last empirical chapter evaluated the channels through which RE stimulated energy use across productive sectors of major developing/emerging economies, namely Brazil, Russia, India, Indonesia and China. To achieve this, the essay relied on duality theory to decompose changes in energy demand into substitution and output effects through the estimation of a trans-log cost function using data spanning 1995-2009. Findings reveal that energy use elasticities across sampled sectors/countries are dominated by substitution effects. One intriguing result that also emerges from this analysis is the role of economies of scale and factor accumulation, rather than technical progress, in giving rise to eco-nomic growth and energy consumption in these countries during the period under consideration.

Money Matters: An Examination of Special Education Characteristics in Efficient and Inefficient Texas School DistrictsHarris, Pakethia 18 October 2018 (has links)
This study veers from the traditional perspective of examining school efficiency or productivity as a cost minimizing process, in which educational inputs are minimized to achieve maximum outputs (student performance). Instead, it provides a critical examination of the dominant, cost minimizing assumption associated with efficiency models and suggest schools instead behave similarly to budget maximizers as presented in Niskanen’s (1971) seminal budget maximizing framework. The study examines the relationship between total student expenditures and subsequent student outcomes, establishing the relative efficiency of Texas school districts using stochastic frontier analysis within a budget-maximizing framework. Additionally, the study investigates how special education populations are structured within those districts deemed efficient or inefficient.
The results of the study concluded that district efficient type did not result in different educational outcomes for students with disabilities. While analysis revealed that inefficient districts spend almost twice as much as efficient districts, no other significant differences were identified among districts type based on the percentage of students receiving special education or student performance. This study contributes to the growing need to identify more appropriate estimation techniques for measuring school productivity and how students with special needs should be included in the education productivity conversation.

Gravitační model a efektivita obchodu mezi Čínou a zeměmi EU: Visegradská skupina, Německo a Rakousko / Gravity model and efficiency of trade between China and EU countries: Visegrad group, Germany, AustriaPapoušek, Radan January 2017 (has links)
Bibliographic note Papoušek Radan. Gravity model and efficiency of trade between China and EU countries: Visegrad group, Germany, Austria. Praha 2017. 87 p. Master's thesis (Mgr.) Charles University in Prague, Faculty of Social Sciences, Institute of Eco- nomic Studies. Supervisor: doc. Ing. Vladimír Benáček CSc. Character count: 115 210 Abstract The thesis analyzes bilateral trade between China and Visegrad group (V4), Austria, and Germany. I use panel data of 23 countries across 1995-2015 to esti- mate gravity model. I compare the countries among themselves (time-series view) and analyze the development of the crucial variables employed in the model (cross- sectional view). Further, I estimate efficiency scores based on stochastic frontier analysis (SFA). Connecting the findings from all three perspectives provides com- prehensive picture of the trade relations of the given countries with China. The thesis reveals that accession to EU was beneficial for trade between V4 and China. Global value chains (GVCs) also help to intensify the trade exchange between the European countries and China. I find that Austria and Germany exhibit higher effi- ciency scores for their exports mainly due to better positions in global value chains. V4's trade balance with China is very sensitive to the decisions of the international...

Public Organization Adaptation to Extreme Events Evidence from the Public Transportation SectorJanuary 2020 (has links)
abstract: This dissertation consists of three essays, each examining distinct aspects about public organization adaptation to extreme events using evidence from public transit agencies under the influence of extreme weather in the United States (U.S.). The first essay focuses on predicting organizational adaptive behavior. Building on extant theories on adaptation and organizational learning, it develops a theoretical framework to uncover the pathways through which extreme events impact public organizations and identify the key learning mechanisms involved in adaptation. Using a structural equation model on data from a 2016 national survey, the study highlights the critical role of risk perception to translate signals from the external environment to organizational adaptive behavior.
The second essay expands on the first one to incorporate the organizational environment and model the adaptive system. Combining an agent-based model and qualitative interviews with key decision makers, the study investigates how adaptation occurs over time in multiplex contexts consisting of the natural hazards, organizations, institutions and social networks. The study ends with a series of refined propositions about the mechanisms involved in public organization adaptation. Specifically, the analysis suggests that risk perception needs to be examined relative to risk tolerance to determine organizational motivation to adapt, and underscore the criticality of coupling between the motivation and opportunities to enable adaptation. The results further show that the coupling can be enhanced through lowering organizational risk perception decay or synchronizing opportunities with extreme event occurrences to promote adaptation.
The third essay shifts the gaze from adaptation mechanisms to organizational outcomes. It uses a stochastic frontier analysis to quantify the impacts of extreme events on public organization performance and, importantly, the role of organizational adaptive capacity in moderating the impacts. The findings confirm that extreme events negatively affect organizational performance and that organizations with higher adaptive capacity are more able to mitigate those effects, thereby lending support to research efforts in the first two essays dedicated to identifying preconditions and mechanisms involved in the adaptation process. Taken together, this dissertation comprehensively advances understanding about public organization adaptation to extreme events. / Dissertation/Thesis / Doctoral Dissertation Public Administration and Policy 2020

Unleashing Profitability: Unraveling the Labor-R&D Nexus in SaaS Tech Firms : An Analysis of the Profitability Dynamics in SaaS Tech Firms through Stochastic FrontierAtla, prashant, Salman, Noräs January 2023 (has links)
Background: High-tech's rapid growth and prioritization of expansion over profitability can lead to vulnerability in economic downturns. The SaaS market, a part of the high-tech industry, offers affordable and flexible software solutions but is also susceptible to market volatility. To succeed, SaaS startups must strike a balance between growth and profitability. Stochastic frontier analysis can measure technical efficiency and productivity in the SaaS market, offering insights into resource and labor utilization. We present an empirical study that explores factors that influence a firm's profitability, aiming to inform decision-making for SaaS companies. Purpose: Our academic work is centered around gaining a comprehensive understanding of the Software-as-a-Service (SaaS) market and the role of labor and research and development expenses toexplore these factors and their influence on a firm's profitability. This study seeks to address this gap in knowledge by conducting an empirical analysis to examine the technical efficiency distribution among SaaS firms, with the aim of gaining insights into resource and labor utilization. By analyzing technical efficiency distribution among SaaS firms, the study will provide insights into resource and labor utilization and its effect on profitability. The research questions will focus on the relationship between technical efficiency, labor utilization, and production functions on profitability. Methodology: We utilized Model I - Cobb Douglas Panel Data Regression with Fixed Effects, Model II - Cobb Douglas Panel Data Stochastic Frontier Analysis using the Kumbhakar and Lovell (1990), and Model III - Transcendental Logarithmic Panel Data Cobb Douglas Stochastic Frontier Analysis using the Kumbhakar and Lovell (1990). These models allowed us to measure the technical efficiency of SaaS firms and examine the interplay between various variables, such as employee count and R&D expenseswith liabilities and assets as control variables. Results and analysis: The three models revealed that labor, assets, and R&D expenses positively and significantly affect profitability in SaaS firms. The SaaS industry also exhibits decreasing returns to scale in two models, suggesting that increasing all inputs proportionally leads to a less-than-proportional increase in output with the third model exhibiting an increasing return to scale. Also, top performers in technical efficiency tend to have higher marginal product of labor (MPL) values than bottom performers.Conclusions: Technical efficiency is positively correlated with profitability, indicating that more efficient SaaS firms achieve higher profitability levels. The relationship between technical efficiency and profitability is stronger when using the Translog model compared to the Cobb-Douglas model. The study also found that the factors contributing most to profitability in SaaS firms are the number of employees and assets, followed by research and development expenses. Recommendations for future research: Further studies could explore the extent to which factors such as the quality of the workforce, technology, and business processes impact MPL and technical efficiency in SaaS firms. Additionally, future research could investigate the effects of market competition, firm size, and industry regulation on profitability in the SaaS industry. Finally, research could investigate the potential benefits of diversifying investment portfolios to include SaaS stocks, given the significant impact of labor, assets, and R&D expenses on profitability.
