This paper proposes a stochastic frontier model for measuring both technical and environmental performance at the mine level by using a translog production function. The Kardia Field opencast lignite mine of the Greek Public Power Corporation (PPC), S.A. is the topic of the case study. Efficiency ratings are derived over a long period of time using annual operating data, and in addition, the determinants of inefficiency are established by means of the technical inefficiency effects model. In the light of the results, there is a strong correlation between technical and environmental efficiency; the results are validated by those produced by data envelopment analysis (DEA). In addition, the stripping ratio is identified as the statistically significant determinant of performance. The proposed framework could be used as an instrument to measure the efficiency of lignite mining operations and to identify the drivers of performance.

This paper analyzes the inefficiency convergence of Indonesian banks using StochasticFrontier Analysis and panel data estimation, covering the period after financial crisis2008 until 2017. This paper also investigates the determinant of this inefficiencyimplying the convergence. To estimate the inefficiency rate, proxied by price ofloan, this paper uses three inputs including price of labor, price capital, and price offund. Our analysis shows that during 2008-2017 the inefficiency score converged ata speed of 26.2 %. Furthermore inflation, gross domestic product, and exchange ratesignificantly affect the growth of inefficiency convergence. This paper contributes tothe empirical literatures particularly on banking research. Overall, the findings implythat policymakers can mitigate the effects of the global financial crisis by loweringinterest rate, providing fiscal stimulus, as well as protecting the poorest from financialdeterioration.

The main aim of this paper is to analyse the role of privatisation and corporate governance reform and modification in the firm’s organisation for the efficiency of the sample firms. Data Envelopment Analysis estimation will be used to understand the level of efficiency achieved by the Management Decision Unit and the stochastic frontier approach will analyse inefficiency in its components (i.e. if inefficiency is due to an adverse state of the world - statistical noise - or if it can be explained with the determinant of other factors such as corporate governance).

This study examines the determinants of cost efficiency commercial banks’ in Ethiopian using balanced panel data with a sample of 13 commercial banks over the period 2010-2017 by paying a translog stochastic cost frontier approach. The identification and selection of inputs and outputs variables was based on the intermediation approach. Accordingly, three input variables (cost of labor, cost of capital, and cost of fund) and two output variables (total loans and other earning assets) are used in the study. Furthermore, five banks specific and one macroeconomic variable are included to examine their effect on cost efficiency. So as to examine the effect of determinant variables which are associated with banks efficiency, a single stage maximum likelihood estimation method is applied to stochastic frontier cost function. The empirical estimations were accomplished by Appling a single stage maximum likelihood function assimilated into Stata software. The estimation is based on conditional mean model concepts. The finding shows that from bank specific factors, return on assets (ROA), and intermediation ratio have positive and significant for intermediation (IR) and insignificant for ROA with cost inefficiency. On the other hand, Bank size (lnTA), Credit risk (CR) and capital adequacy ratio (CAR) have a significant negative coefficient with cost inefficiency. GDP also has negative but insignificant with inefficiency. Therefore, banks are recommended to improve and sustain their efficiency by maintaining available proportion of capital adequacy ratio and attract high value, low interest-bearing demand deposits.

Pemerintah Indonesia saat ini sangat serius memberantas penangkapan ikan ilegal di wilayahnya. Pengurangan penangkapan ikan secara ilegal oleh kapal asing di Indonesia berarti pengurangan persaingan yang signifikan antara nelayan asing dan domestik. Studi ini berpendapat bahwa, dengan menurunnya kompetisi dengan nelayan asing, nelayan domestik harus mampu meningkatkan jumlah tangkapan. Penelitian ini bertujuan untuk mengetahui tingkat efisiensi teknis dan juga faktor penentu inefisiensi nelayan di Indonesia. Penelitian ini menggunakan fungsi produksi yang meliputi usaha nelayan dan capital sebagai input. Analisis stochastic frontier digunakan untuk menguji faktor penentu inefisiensi pada produksi ikan di antara 156 nelayan di seluruh Indonesia. Hasil penelitian menunjukkan bahwa produksi ikan sangat bergantung pada jumlah awak dan jenis kapal sesuai yang diharapkan. Dalam hal inefisiensi, penelitian ini mengklaim bahwa kepemilikan telepon seluler merupakan penentu signifikan untuk mengurangi inefisiensi, diikuti oleh kepemilikan kapal dan nilai alat tangkap. Temuan tersebut menyiratkan bahwa koordinasi antara nelayan, kepemilikan kapal dan alat penangkap ikan penting untuk efisiensi nelayan. Determinants of Fisher’s Efficiency in Indonesia: A Stochastic Frontier AnalysisIndonesian government has been recently fought against illegal fishing in the territory. Reduction in illegal fishing means a significant reduction in competition among foreign and domestic fishers. This study suggests that domestic fishers must be able to increase their fish capture as the competition with foreign fishers decreased. This study aims to identify technical efficiency level as well as to identify the determinants of inefficiency among fishers across Indonesia. This study utilizes a production function including fishers’ efforts and capital as input. A stochastic frontier analysis is used to examine the inefficiency determinants on fish production among one hundred and fifty six fishers across Indonesia. The result indicated that fish production depended significantly on the number of crew and expected type of boat. This study claims that cell phone is a significant determinant to reduce inefficiency, ship ownership and the value of fishing gear respectively. These finding implies that coordination among fishers, boat ownership and fishing gear are necessary for the fishers’ efficiency.

The degree of organizational efficiency of a firm is a crucial determinant of its business success. But, organizational efficiency itself is dependent on the level and effectiveness of the organizational effort spent by the firms. This paper by Rameshan and Trivedi, therefore, attempts to examine the inter-firm variations in the intra-firm allocation of organizational effort. It also focuses on the effectiveness of the effort allocated to different areas of action which is required to tackle the scores of inefficiency elements prevailing in the firms.

Objective: The broiler business with the partnership model has become a choice of society in improving their living. In certain circumstances, however, broiler farmers receive income far beyond their expectations due to declining production, because of some impacts of inefficient input utilization and worse management. The research, then, aims to estimate the technical efficiency of broiler farming business with an open house system and a partnership business pattern, as well as to analyze the determining factors.Methods: The purposive sampling was employed to identify 80 farmers. In detail, the parameter of production function of the Stochastic Frontier was estimated by using Maximum Likelihood Estimations (MLE) method and Frontier 4.1 program. Results: The estimated value in the statistic model (γ=0.8634) depicts that the hypothetical result of the production function model was assumedly better, so the production function of Cobb-Douglas was able to explain the existing data related to a phenomenon of the technical inefficiency in broiler business. The calculation result of the value of restriction parameter of LR test was 89.99, was greater than the critical value of the Kodde and Palm Table (=19.384), by the significance level at p<0.01. This means the existing inefficiency effects in the stochastic model. Further, the value of sigma square with the parameter value of 0.0133 was statistically significant by the trust level of 99%, describing that the production variation contributed by technical inefficiency was 1.33%. Conclusions: In conclusion, the value of technical efficiency obtained by broiler farmers under the partnership model in the open-house system was 0.95. Then, the determining variables of the broiler production were feeds, vitamins, medicine, working hours, and the total of electricity. Determinant variables that could reduce technical inefficiency were age, farming experience, and ownership status of lands/cages.

Technical Efficiency in the Small Scale Industrial Sectors of Punjab and Haryana - A Comparative AnalysisThe present study deals with the inter-temporal variations of technical efficiency in the small scale industrial sector of Punjab and Haryana and compares the performance of both states with the small scale industrial sector of India. Data spanning over the period 1972-73 to 2006-07 has been utilized to estimate technical efficiency with the help of data envelopment analysis (DEA) based upon efficiency scores. The empirical analysis confirms that there exists 0.176 percent and 0.470 percent technical inefficiency in the small scale industrial sectors of Punjab and Haryana, respectively. However, at the aggregated All-India level, the technical inefficiency score is 0.449. Thus, the small scale industrial sector of Punjab is comparatively more efficient than that of Haryana and All-India. Moreover, the reform process has adversely affected both the managerial and scale efficiencies of Haryana, whereas an improvement in managerial efficiency has been observed in the small scale industrial sectors of Punjab and All-India. The empirical analysis showed that in the post-reform period both at the All-India level and in Haryana technical inefficiency scores are increasing, whereas in Punjab it is decreasing. Thus, it can be inferred that scale efficiency is an important determinant of technical efficiency in explaining the performance of the small scale industrial sectors of Punjab and Haryana.

The determinant of the credit risk of banks in a developing country have limited data to analyze and limited participation in literature. Determinants of credit risk are very important in order to define the non-performing loans (NPL) in Kosovo banking systems. Even though banking system in Kosovo is the newest in region, it is comparable with banking systems to all places in regions (Albania, Serbia, Montenegro, Macedonia, Bosnia and Herzegovina, etc.).The main purpose of this paper is to classify some factors that influence credit risk in commercial banks in Kosovo. The research includes seven commercial banks for the period 2006–2015. Data analysis and interpretation are processed with Statistical Program for Social Sciences SPSS v.19.0.The effect of variations in the determinants of credit risk exposure is based on using a multivariate panel regression model. Our empirical results suggest that a significant relationship exists between credit risk and the following variables: Profitability (ROE and ROA), Inefficiency (IE), Loans to deposit ratio (LDR), Credit growth (CG) and Deposit rate (DR), while variables of Solvency (SR) and Credit rate (CR) are not statistically significant in terms of credit risk.

The changing food demands by the teeming urban population, job search, and sector profitability have made vegetable production indispensable as it contributes to increased incomes and livelihoods of urban dwellers.This study investigated the current level of productive efficiency (technical and allocative) of vegetable farmers in the Kumasi Metropolis using cross-sectional data obtained from 135 sampled farmers using a semi-structured questionnaire. Data analysis was conducted using the stochastic frontier approach to estimate firm-specific technical efficiencies and the factors that influence efficiency levels. The results show that inefficiency exists among the sampled vegetable farmers as they currently achieve an average technical efficiency score of 66.7%. Allocative efficiency estimates for land and labour revealed that both factors of production are over utilised by farmers. The age of the farmer is the main socio-economic determinant of technical efficiency.The study recommends that farmers be educated on the correct use of inputs by extension agents. The government policy of recruiting community extension agents under the ‘planting for food and jobs’ programme is in line with addressing inefficiency in the production sector and should be promoted.

In 1994, the government of Egypt issued a comprehensive environmental law concerning environmental protection from pollution sources in Egypt. The first main goal of this study is to examine to what extent inefficiency scores of plants in both private and public sectors are affected by environmental regulations done by these plants through the period 1996-2001. Most empirical literature on this area focused mainly on developed countries especially the U.S. due to the availability of data. Thus, this study tries to add some to previous literature through examining this relationship under different economic and development stages. To investigate this relationship, we designed and executed a survey of manufacturing plants in three Egyptian cities, and used a stochastic frontier cost function to measure inefficiency levels of plants and test factors affecting these scores. The results of the econometric models indicate that plants more affected by environmental regulations are associated with higher inefficiency levels. Also, we find strong evidence that plants working under private ownership are more efficient than public plants. Additionally, these results reveal that plant-size has a negative effect on inefficiency levels, which mains that larger plants are more efficient than smaller ones. However, the effect of plant-age on cost inefficiency is ambiguous. The second goal of this study is to examme possible factors determining plant's environmental performance. Two methodologies (truncated regression and ordered probit model) are used in this part depending on dependent variable used. Results of the truncated regression highlight the role played by regulators, market pressures, and worker security as the main factors accounting for plants' environmental performance. Plants face high international competition, produce final consumer goods, and subject to high rate of inspections are more likely to have better environmental performance. Results of the probit model reveal that plant characteristics have a significant effect on plant's environmental expenditure, where private, older, and larger plants tend to spend more in environmental concerns. Also, variation in inspection rates and consumer pressures are seen to have a strong impact on plant's environmental expenditure.

This chapter lays out one part of the theoretical framework of the book, drawn from institutional economics. This literature maintains that institutions are the main determinant of long-term growth, and that to remain ‘appropriate’ institutions must evolve in synchrony with an economy’s progress through the stages of its development. Their evolution depends on a society’s openness to political creative destruction. Limited-access social orders tend to constrain it, to safeguard elites’ rents, and typically undermine progressive institutional reforms, breaking that synchrony. The transition from that social order to the open-access one is an endogenous and reversible process, in which inefficient institutions, which allow elites to extract rents, coexist with appropriate ones, which constrain their power and make it contestable. The hypothesis is advanced that Italy has not yet completed this transition, and that the tension between its efficient and inefficient institutions can endogenously generate shocks, which open opportunities for equilibrium shifts.

Having collaborated with the community to decide upon the objectives, identified the major threats to be addressed, considered the possible options and assessed the evidence, the next stage is to decide what to do. Many decisions can be decided easily, as either obvious or trivial, thus requiring no additional assessment of different stages of the process. The harder decisions then require assessing the likely consequences of options and determining the preferred trade off. There is a range of approaches for making each of these stages more rigorous, reducing the likelihood of making inefficient decisions. These approaches are described with an account of the situations under which is most appropriate to address the conservation problem.

Social protection can be recognized as one of the most significant social achievements of the last century. In this study one of the most important issues of labour market in Turkey - employment-social protection relationship - will be evaluated. It can hardly be argued that Turkey has a comprehensive social protection system. An important part of people who are at the age of working are not covered by the social security system with reasons such as: low labour force participation rate, prevalence of informal employment, child labour, high share of employment in the agricultural sector, the weakness of the social security system and problems of labour market regulation. This situation increases the need of social protection systems. On the other hand, weakness in coordination between the institutions those operate in the field of social assistance and lack of appropriate criteria in determining the real people in need cause inefficient and inadequate supplying of services and inefficiency in using sources.

The works of Leibenstein emphasize the existence of x-inefficiency in organizations that explains why firms apparently identical, with the same composition of the workforce and the same technology, are able to realize very different performance. On the basis of Leibenstein and Maital (1994), this chapter presents the sources and reasons for the persistence of x-inefficiency by mobilizing the organizational learning theory and by determining the possible strategies for the correction or the elimination of x-inefficiency by using games theory. Moreover, the establishment of a favorable climate for learning can promote knowledge transfer, which in turn helps to improve innovation, and consequently, achieving organizational efficiency.

This chapter leads a complex research study on the determinants of bank cost efficiency in transitional economies based on empirical evidence for Latin America, Central, and Eastern Europe, and South-East Asia. The empirical results suggested that banks, which follow a more cautious strategy, characterized by lower risk appetite and average expectations on profitability, have higher cost efficiency. Moreover, the empirical evidence highlighted the fact that a higher gross domestic product growth rate implies an increase in the inefficiency level, indicating an unsustainable bank management behavior, which in periods of economic growth adopts policies that can generate inefficiency in order to gain market share and to obtain higher bonuses. The global financial crisis has had a high negative impact on the banking system in transition economies.

Corporate governance systems around the world are shaped by legal traditions, but the most important determinant of their effectiveness is law enforcement. Developing countries tend to have weak institutional structures and contracting environments. In this context, markets are inefficient and ownership concentration becomes the main corporate governance mechanism in order to protect property rights. How can developing countries design an optimal corporate governance system in their poor business environments? Corporate governance mechanisms are interdependent, and each country needs to search for a set of mechanisms in equilibrium—that is, an optimal combination of control and incentives—that solves its own agency problems. But another problem in developing countries is the lack of public enforcement. Just as internal mechanisms may substitute for ineffective external mechanisms, private initiatives may reinforce weak public enforcement.

This chapter examines the competitiveness of product markets in Greece. One of the main determinants of competitiveness is the quality of the set of rules and regulations that govern the operation of markets. These should promote competition, investment and entrepreneurship. Heavy and low-quality regulation is generally associated with greater inefficiency and poor economic outcomes. This chapter describes competitiveness in the Greek economy and its evolution over time using various internationally comparable indicators that cover many dimensions of competitiveness. It demonstrates that product markets in Greece are among the most heavily and misregulated markets of advanced countries, though the reforms that took place during 2011–2014 had a positive impact. The chapter investigates in greater depth the misregulation of product markets, identifying possible causes and illustrating through case studies. It makes the case for a National Competition and Competitiveness Policy plan to improve the regulatory institutions and reduce regulatory burden. Finally, it looks at the successes and failures of regulatory reform history in two important markets: energy and telecommunications.

Shape Expression (ShEx) is a novel schema language proposed for RDF/graph data. For a ShEx schema S and a query q, q is said to be unsatisfiable if for any valid data D under S q reports an empty answer over D. In general, the size of RDF/graph data is very large, and thus it is inefficient to perform unsatisfiable queries on such data. Therefore, it is desirable that we can detect unsatisfiable queries efficiently before executing them. In this paper, we consider Conjunctive Property Path, a generalization of Property Path defined in SPARQL 1.1, as the query language. First, we propose an algorithm for determining satisfiability of Conjunctive Property Path queries under ShEx schema. Then we conducted a preliminary experiment, which results suggest that the proposed algorithm determines if a given Conjunctive Property Path query is satisfiable efficiently.

The conception of the Responsibility to Protect (R2P) was developed to resolve the practical problem of the inefficiency of the international community to address atrocities. The present contribution aims at the clarification of the theoretical problem on the nature of R2P norm and provision of conceptual tools for its solution. After differentiating R2P objects and contouring their content, the question whether the R2P norm is of a legal kind will be addressed. The contribution claims that application of the proposed legal concepts – theoretical conception related to the law, doctrine, norm, principle and rule – contributes to the clarification of the objects and content of the R2P; and that political responsibility approach to the identification of a legal norm and the specific concept of emerging norm are suitable tools for determining the legal nature of R2P norm.

The present paper describes the behavior of the capital and operating cost as driving forces for the design of the first stage of enrichment of heavy water production by the Girdler Sulfide (GS) process. A very useful procedure for analyzing a process or control system is by means of the Second Law of Thermodynamics. Determining where the irreversibilities of a process or control systems are generally indicates where the greatest improvements can be made, particularly as they relate to operating cost. Thermodynamic analyses based on the concepts of irreversible entropy increase have frequently been suggested as pointers to sources of inefficiency in chemical processes. Furthermore, this study shows a generalized discussion of the cost with respect to the optimization parameters, it points out where the irreversibilities of the process are located, and provides a generalized discussion from the successful application of the technique.

As a result of comprehensive analysis of socio-economic situation in Kyrgyzstan regions it is worked out a method of ranking regions based on aggregation of various indicators determining important factors of region economic position. The rating of regions can be used for purposes of definition of investment attractiveness and providing transparency and reliability based on data of statistical institutes. The final result of the correlation analysis of the relationship between the growth rates of investment volume and the growth rates of the gross regional product showed that the relationship between them is very weak, which characterizes the inefficient use of investment resources.

It cannot be said that military expenditure and economic growth relationship have reached a consensus both theoretically and empirically. The basic argument of the claim that military spending will increase national income is that if the economy is unemployed, the increase in spending, including military spending, will increase national income by expanding demand. Whereas, the argument that military spending will have a negative impact on the national income is claimed due to causing the inefficiency of the resources in the economy and thus to suppress the growth by causing resource mobility from productive sectors to the non-productive sectors. On the purpose of determining which of these two opposing ideas whether committed in Turkey’s economy, military expenditures have been added to Solow growth model and econometric analyzes have involved the period of 1980-2016. In the light of findings, it is revealed that second type of hypothesis is valid that military spending has a negative effect on economic growth.

The computational method presented in this paper provides an efficient solution to the reliability problem of burst of pipes with random geometric imperfections. The statistical characterization of the geometric imperfections is based on measured data from seamless pipes. Application of the Model-Correction-Factor Method (MCFM) proves that the burst pressure for a given pipe depends almost entirely on its minimum wall thickness. Thus, the burst reliability problem becomes one of determining the probability distribution of minimum wall thickness from the imperfection statistics. This problem is solved approximately by application of reliability theory and a novel homogenization technique. The accuracy of this method is verified through computationally inefficient Monte Carlo simulation for selected cases.

Sugar is one of the most important elements in human nutrition. The Common Market Organisation for sugar has been a subject of considerable debate since its establishment in 1968. The European agricultural market has been criticized for its heavy regulations and subsidization. The sugar market is one of the most regulated ones; however, this will change radically in 2017 when the current system of production quotas will end. The current EU sugar market changed is structure during the last several decades. The significant number of companies left the market and EU internal sugar market became more concentrated. The aim of this paper is presentation characteristics of sugar market with respect to the supposed market failure – reduction in competition. The analysis also identifies the main drivers and determinants of the EU especially quota sugar market. In relation to paper’s aim the following results are important. The present conditions of the European sugar market have led to market failure when nearly 75 % (10 million tonnes) of the quota is controlled by five multinational companies only. These multinational alliances (especially German and French one) are also taking control over the production capacities of their subsidiaries. In most countries, this causes serious problems as the given quota is controlled by one or two producers only. This is a significant indicator of market imperfection. The quota system cannot overcome the problem of production quotas on the one hand and the demand on the other; furthermore, it also leads to economic inefficiency. The current EU sugar market is under the control of only Sudzucker, Nordzucker, Pfeifer and Langen, Tereos and ABF.

Abstract An important aspect of well test and well clean-up operations is the need to produce and responsibly manage the hydrocarbons, typically through flaring, which is potentially an environmental concern. This challenge has received significant attention over the past few decades and remains a major concern today, especially in offshore environments, considering rising requirements for safe disposal of large volumes of crude and gas as well as completion fluids and possibly formation water produced. Despite multiple alternative fluid disposal methods available today, in some cases, conventional hydrocarbon flaring may still be an optimum, cost-effective solution for a short duration of welltest or well clean-up operations. The high-efficiency burners and flare tips used today have proven their efficiency over the years; however, due to the dynamic nature of the well test operations, fast wind direction changes, variation of fluid types and properties, and the inefficiency of the fluid separation process, the actual operational efficiency often can be compromised increasing the risk of health, safety, and environment (HSE) incidents. These incidents can be prevented by a continuous dynamic flare monitoring system. The inefficiency of the fluid disposal process can significantly constrain the operations, limiting achievable objectives and increasing the risk of HSE incidents. The combustion performance efficiency of modern high-efficiency burners used today has been practically proven over the last several decades and well studied and can now be modelled for operating conditions and create an operating burner envelope by using proprietary flare monitoring software. This software can also be used to estimate the required number of air compressors prior to the test to achieve high operating efficiency. Many factors influence burning and flaring efficiencies, such as the composition of production fluid, wind speed, and wind direction; these affect the requirements of air supply and must be monitored for efficient flaring. Integration of the software used for determining the operating envelope and dynamic flare monitoring and surveillance with new-generation data acquisition software acquiring information from additional sensors and cameras pointed on the flare and using AI algorithms enables the evaluation and adjustment of the burner and flare efficiencies in real time according to actual operating conditions. Proprietary algorithms used by the software can estimate the environmental emission of CO2, CH4, and CO2e in real time during the well test operations. This paper describes an innovative platform that is based on the unique combination of hardware and software and provides an integrated solution for dynamic flare monitoring and emission reporting during well test operations. The paper also summarises the results and lessons learned from the application of the dynamic flare monitoring system during multiple welltest and well clean-up operations performed offshore and onshore.
