This article applies frontier production function analysis to small farms in Nicaragua during 1998-2005 (Battese and Coelli, 1988). The objective of this study is to estimate an average function that will provide a picture of the shape of the organic fertilizer technology of an average firm (in our case, agricultural production units). Furthermore I present a best-practice of organic fertilizer against which the efficiency of the firms within the primary sector can be measured (Coelli, T: 1995). The results show an average of technical efficiency acceptable which the makers of public policy in Nicaragua must considerer for the future. It is imperative if we consider an economy activity indexes that have increased during this period.

October 2007


58 Reads

The paper is about application of evolutionary concept, particularly the application of natural selection process, to the study of movie industry. The importance of the application is that it allows for the heterogeneity and interdependency of market agents in analyzing the economic choice decision. This complexity always presents an obstacle to the study of market behavior, especially when one has to take into account the constant reinforcing effects among the variables, which often renders the problem elusive. The paper intends to explain the economic process, particularly the evolution of exhibition contract, taking into account this complexity through the use of evolutionary concept.

Since leadership is a critical factor for improving organizational performance, failure or success of an organization highly depends on the efficiency of leadership at all levels. Scholars elaborated that leadership is the ability of influencing one's attitudes, aptitudes and beliefs, in the way that it will lead to meet organizational objectives. The main purpose of this study is to consider two domains of efficient leadership and women’s leadership style, in order to determine and elaborate the dimensions of the new concept of “Women’s Efficient Leadership”. We intend to describe the characteristics of women’s efficient leadership in state organizations in Iran by means of offering a logical pattern, in order to be able to propose a favorable pattern, leading to increased efficiency in governmental organizations of the country. Innovation of this study can be divided into two parts: one is theoretical contribution and developing the knowledge of efficient leadership as well as women’s leadership style, and the second one is scientific contribution and proposing a pattern for women’s efficient leadership in state organizations, using compound approach. The outcomes of this study show that women’s efficient leadership in state organizations consists of 7 subjects, 17 dimensions, and 85 components, which represent various characteristics in different periods of time. The thesis that women’s efficient leadership has an evolving nature was approved and that it consists of a combination of factors such as capability of team making, having vision, cognitive and psychological capabilities, able to bring continuous improvement of organizational performance, mentoring and making effective relations. In this study, the influence of mentioned factors on women’s efficient leadership has been investigated by means of questionnaires and has been approved.

The purpose of the paper is to determine the extent to which Nigeria's National Transport Policy (NTP) enhances economic sustainability in Nigeria and offer guidance to policy makers on effective ways to make progress towards sustainable transportation in Nigeria. This paper offers an analytical evaluation of the Policy, using both primary and secondary data. To do this quantitative survey method was adopted for the study and questionnaires were used for data collection instrument. A random of 127 (68.28%) transport companies were selected for the study, out of a population of 186 registered luxury bus and shipping companies in Nigeria in 2009. For a proper analysis, a sample of 400 non transport workers was included in the study. In total, 1670 questionnaires were administered to the respondents, out of which 1452 questionnaire were completed, which represents a response rate of 86.95%. The data analysis revealed that overall means score was 2.54, which was lower than expected value of 3.00 on 5-point Likert Scale. The test of hypothesis revealed that calculated Z was -27 .9590, with significant probability of 1.0000, which was greater than 0.05. The test was insignificant at 5% level of significance. Therefore, it was concluded that the extent to which the policy enhances economic sustainability in Nigeria, was not significantly above average. This implies that the policy had little influence in reducing negative economic impact emanating from Nigeria’s transport system. In this light, it is recommended that the policy should be modified so as to make it functional and goal oriented.

An efficient XML query pattern mining algorithm for ebXML applications in e-commerce

February 2012


48 Reads

Providing efficient query to XML data for ebXML applications in e-commerce is crucial, as XML has become the most important technique to exchange data over the Internet. ebXML is a set of specifications for companies to exchange their data in e-commerce. Following the ebXML specifications, companies have a standard method to exchange business messages, communicate data, and business rules in e-commerce. Due to its tree-structure paradigm, XML is superior for its capability of storing and querying complex data for ebXML applications. Therefore, discovering frequent XML query patterns has become an interesting topic for XML data management in ebXML applications. In this paper, we present an efficient mining algorithm, namely ebXMiner, to discover the frequent XML query patterns for ebXML applications. Unlike the existing algorithms, we propose a new idea by collecting the equivalent XML queries and then enumerating the candidates from infrequent XML queries in our ebXMiner. Furthermore, our simulation results show that ebXMiner outperforms other algorithms in its execution time.

The 2008 Financial Crisis: A Moral Crisis of Capitalism

May 2011


552 Reads

Both success and failure of free market economy could be explained through its understanding of human nature. Its great success in production comes from its principles based on “self-interested” human nature driven by animal souls and egoistic desires. The system achieves higher productivity by providing many incentives to motivate people whose goals are to maximize their interests. On the other hand, the failure of the free market system comes from its lack of moral principles to balance irrational and irresponsible decisions/behaviors of animal souls and ego. For that matter, the paper argues that the 2008 crisis was essentially a moral crisis of capitalism with its root going back as far as the Enlightenment. It suggests that during the crisis, the “invisible hand” of free market turned to “stealing hand” through market games driven by the irrational and irresponsible behaviors of politicians, creditors, and consumers. The paper concludes with few lessons learned from the crisis. First, the crisis created a great opportunity to acknowledge the need for moral values for efficient market system. Second, we should revise our assumptions of human nature and behaviors in economics and finance to include predictably irrational decisions of individuals. Third, we should include moral education in education system at K-12 levels, not at the college. Finally, we should revise our economic models to capture the importance of moral and spiritual capital as endogenous variables.

Because of efficiency and easiness that it provides, Information Technology (IT) usage has a vital meaning for all sectors. To derive benefits from IT completely, it has to be discovered in all aspects. The purpose of this study is to investigate the reasons behind accountants’ IT usage and in this context, compare two social psychology based theories; the Theory of Reasoned Action (TRA) and the Theory of Planned Behavior (TPB). The data, obtained through a questionnaire that was responded to by 437 accountants, shows that if an accountant has a positive attitude and Subjective Norms (SN) towards IT usage, his/her intention towards IT usage is also positive, and the degree of intention is in proportion to the degree of perceived behavioral control. According to the stepwise regression analysis, TPB has higher predictive power than TRA.

November 2011


657 Reads

Workplace bullying represents persistent behaviors that are both overt and covert. There is an increasing need for understanding this construct for the reason that it is directly linked to bringing the victim to a state of long lasting emotional distress. Alarmingly, such aggression usually is invisible and difficult to identify. This provides a rationale for elucidating the concept of bullying in the workplace at length through an extensive review of the existing literature. Various facets of workplace bullying have been highlighted in this paper in order to show its detrimental effects on the health of targets working in any occupational or organizational setting. Drawing on well-established theories and findings of various researchers, the concept of workplace bullying is systematically linked with how it can evolve into mental health problems. In addition, few hypotheses are also presented for future research purpose.

Are Currency Areas Feasible in East Asia? A Benchmarking Approach

October 2009


33 Reads

This paper evaluated the feasibility of optimum currency areas (OCAs) in East Asia by benchmarking the characteristics of 16 East Asian economies and India against those of the dollarized countries and the European Economic and Monetary Union (EMU), according to criteria that are most frequently studied in OCA literature, namely synchronization in real business cycle, volatility in real exchange rate, and synchronization in real interest rate cycle. Backed by literature, the U.S. dollar was set to be the reference currency. Data series were divided into different time periods to capture different economic circumstances. A ‘dynamic’ benchmarking technique was used to ensure robustness of results. Results suggested that the region as a whole does not constitute an OCA at the moment. Nonetheless, a subregional union of a high potential ‘Southeast Asian’ bloc was put forward. Results serve to be an important reference for both public and private policymakers on matters pertaining to regionalization and international business management.

The Impact of Institutional Ownership on Risk-Taking Behaviors

March 2012


207 Reads

One of the major factors influencing a company’s performance is undoubtedly the level of risk-taking. As owners of a great deal of company stock, institutional investors can play an important role in determining this level. Therefore, this study has investigated the influence of institutional ownership on the risk-taking behavior of companies that are listed in the Tehran stock exchange. The study has used the standard deviation of monthly return and systematic risk (β) as market risk criteria, and research and development expense and capital expenditure as company risk criteria. This research includes 58 companies from 2004 to 2008, in which ordinary least squares regression models (panel data) and a tobit model have been used. The results show that no meaningful relationship exists between the percentage and concentration of institutional ownership by stockholders and risk-taking behavior.

The Behaviour of the Istanbul Stock Exchange Market: An Intraday Volatility/Return Analysis Approach

May 2011


110 Reads

This study investigates intraday effects in the Istanbul Stock Exchange (ISE) during the latest period of financial turmoil which began in August 2007 and extended to February 2010. We tested for the possible existence of intraday anomalies using both return and volatility equations, empirically applying GARCH (p,q) models. The unique data set we utilized was compiled from 15-min intraday values of the ISE-100 Index which are formed by averaging historical ten-second tick data. This study contributes to the current literature in three distinct ways. Firstly, the basic characteristics of the unique data used in this research were investigated in detail. Secondly, four range-based volatility measures, namely Garman Klass (GK), Yang-Zhang (YZ), Rogers-Satchell (RS) and Parkinson (PK), were employed to take more precise measurements of volatility for intraday data analysis in order to identify the changes in general market sentiment using opening, closing, high and low prices. Thirdly, we estimated the relative efficiency of GK, YZ, RS and PK by applying GARCH (p,q) models. The results are quite promising, indicating that strong opening price jumps are present for daily and morning calculations. They illustrate that the YZ estimator has relatively more power in generating tolerable volatility patterns.

Continuous-Time Evolutionary Stock and Bond Markets with Time-Dependent Strategies

December 2008


36 Reads

This paper develops a general continuous-time evolutionary finance model with time-dependent strategies. It is shown that the continuous model, which is a limit of a general discrete model, is well-defined and if there exists one completely diversified strategy in the market, then there is no sudden bankruptcy. After that a deterministic evolutionary bond market is studied in detail. It is certified that a bond market is evolutionary stable, which is equal to arbitrage-free if and only if the total returns defined in this paper across all the assets are the same, or each bond is evaluated by an improper integral in which the integrand is a discounted value of the dividend payoff with the discount rate being market consumption parameter. Last an approach to compute the benchmark interest rate is provided.

August 2012


76 Reads

The purpose of this paper is to demonstrate the concept of global branding, what it stands for being socially responsible, and what its link with leverage is. It also highlights the range of social responsibility issues with reference to Pakistani brands and explores the relevant issues and deep insights from strategic corporate social responsibility (CSR) literature and global branding literature in the context of Pakistani organizations. It also suggests future implications for theorists, practitioners and academicians with reference to effective strategic CSR and global branding. This paper embarks on the intellectual journey with the concept of CSR and global branding in local context of Pakistan, while reviewing the relevant literature and addressing the issue of complexity in Pakistani context. This study gives insights about the issue of complexity at the time of strategically integrating CSR into global band and sorts out three strands of complexity namely, 1) issue complexity, 2) organizational complexity, and 3) communication complexity in the context of Pakistan. The limitation of this paper is due to the limited academic literature, giving insights about how global organizations in corporate CSR initiatives for the development of brands, and insights dealing with the issues needed to be taken into account at the time of integrating into branding strategies. This paper gives fresh enquiry to the issue complexity, organizational complexity and communication complexity with reference to global brands and CSR activities in the context of Pakistan which has been applied so far.

June 2010


277 Reads

The work desires to determine the optimum level of batch size in bottleneck facility and to analyze the effect of common processes on throughput and cycle time in a production system under uncertain situations created by machine breakdown and quality variation. Few simulation models are developed based on a live case from a company. The models are verified and validated with the historical data from the company and by face validity. Taguchi approach for orthogonal array is used in designing experiments. The experimental settings are executed in WITNESS, a simulation package. It is observed that the variation in level of common process in the system has significant impact on the production quantity and cycle time. The main contribution of this research is determination of the optimal level of batch size in a bottleneck resource under imperfect quality of product and resources breakdown uncertainties. This approach can be generalized to any multistage production system, regardless of the precedence relationships among the various production stages in the system.

The Corporate Cash Holdings: Determinants and Implications

December 2011


306 Reads

Several empirical studies have reported that the level of short-term financing is higher in firms operating in developing countries. Short-term financing increases risk of default as it matures quickly and leaves little room for the borrowing firm to manage its cash flows. But if the firm has a cash buffer, it can avoid such a risk. If firms in developing countries have higher level of short-term debts, do they carry larger cash balances too? Do firms in Pakistani match the maturity of assets with the maturity of their debts? In this study, we investigate these questions using a sample of 380 listed firms over a period of 1996 to 2008. The descriptive statistics show that cash-to-total assets ratio of the sampled firms is almost the same as reported in other empirical studies for developed countries such as US and UK. This finding raises an important question of how firms in Pakistan with more short-term financing carry relatively smaller balances of cash. As an answer, this study puts forward several explanations, which have important implications for capital market and firm financing. Results of panel data models indicate that cash-to-total assets ratio increases with growth opportunities, size of a firm, dividends ratio, and decreases with debt-maturity and conversion cycle. To allow for the possibility that cash-to-total assets ratio is adjusted gradually over time by firms in an attempt to reach optimal ratio, the study also employs a partial adjustment model by using the generalized methods of movements (GMM).

Chaotic Processes of Common Stock Index Returns: An Empirical Examination on Istanbul Stock Exchange (ISE) Market

July 2010


377 Reads

The nonlinearity and accompanying concept, namely the chaos receive great attention from researchers. This study employs nonlinearity and chaos theories to examine the behavior of the Istanbul Stock Exchange (ISE) all share equity indices. The main purpose was to explore the existence or nonexistence of nonlinearity and chaotic behavior in the ISE market. Therefore, the efficient markets’ characteristics, which are the random behavior of asset prices and nonlinear chaotic dynamics, were contrasted and the probabilistic and deterministic behaviors of the asset prices were compared. Our results based on BDS, Hinich Bispectral, Lyapunov Exponent and NEGM tests reject the efficient market hypothesis that the index series examined in this study is not random, independent and identically distributed (i.i.d).

July 2011


1,568 Reads

This paper is aimed to determine factors influencing international postgraduate students in choosing university in Malaysia. Factors such as programs offered, fees, promotion, facilities, prominence, environment, convenience, and scholarship were utilized. A total of 135 international postgraduate students were involved in this study through a direct survey. The percentage technique to extract the information of respondents’ demography was used. Then, the analytic hierarchy process was employed to evaluate the level of importance of each factor. The study found that “programs offered” is the number one factor which influences overall international students’ choice to opt for a postgraduate study in Malaysia universities. There were some differences between students from Asian and Western countries in ranking the importance of those factors. Overall categories of respondents selected “tuition prices”, “facilities”, and the “academic staff prominence” as the preceding factors to follow the “programs offered” factor in a sequential level of importance. In general, the result reflects the awareness of prospective students towards the expected standard of education required from the higher education industry.
