Abstract
This study is an attempt to assess the marketable and marketed surplus of selected seasonal fruits (mango, jackfruit, and litchi) in the Chittagong hill tracts of Bangladesh. Primary data were used for the study. In total, 459 sample fruit growers were selected purposively for the study. Proportionate random sampling was followed in case of selecting the sampling unit. It was apparent to interpret from the survey that in case of mango production, 78% fruit grower planted Rangui variety whereas Amrapali was ranked second highest (36%) including the eight groups of Bandarban and Rangamati of the survey. Among the three mentioned varieties of litchi, BARI litchi 2 variety was more prevalent (21%) than the other varieties. Also 69% respondent grew jackfruit whereas the average production was more in Rangamati than in Bandarban area. It is more apparent for all three of the seasonal fruits that, the marketable surplus was found to be higher than the net marketed surplus. That means farmer retains more for their consumption and other uses than the actual amount marketed. Running factor analysis, several cases were found that affect sustainable market linkage which was categorized into four factors like marketing, economic, social and environmental factor and the KMO value was found to be 0.527, generally, indicate that a factor analysis might be useful with this data. This study recommends increasing the marketed surplus with the increase of marketable surplus so that it can ultimately help fruit grower to link themselves with the market and increase their revenue.
Contribution/ Originality
The study is one of very few studies which assess the marketable and marketed surplus of seasonal fruits in the hilly areas of Bangladesh. Since most of the studies deal with the production and marketing system of crops, this study adds the momentum in linking the hill farmer with the market.

Abstract
In the context of multiple energy loads, the energy hub is introduced as a unit where multiple energy carriers can be converted, conditioned, and stored to enhance the energy efficiency of the system. Therefore, this study presents an optimal planning framework, which aims the selection the invested size and time of equipment based on minimizing the life cycle cost considering renewable energy sources (RES) and battery energy storage systems (BESS). The input energies considered include the electrical energy, natural gas, solar radiation and wind that are converted to supply for output energies consisting of electricity, cooling, and heating. The planning framework with the objective function which is minimizing the life cycle cost of the project consists of the investing and operating cost of equipment, cost for purchasing energy from market (electricity, natural gas), the emission taxes cost and the replacement cost or residual value of equipment at the end of the planning period. The constraints as balance energy types, the size limit of equipment integrated into model together with binary variables make a mixed integer nonlinear programming (MINLP) planning problem. The feasibility of the proposed model and the effectiveness of renewable energy sources and BESS in optimal planning of energy hubs are tested by an assumed energy hub with the high-level algebraic modeling software, general algebraic modeling system (GAMS).
Contribution/ Originality
This study contributes in existing documents a novel planning framework which considers the RES and BESS. A MINLP planning framework with the LCC objective function and constraints proposed allows determining the installed size and time of equipment during the planning period. The different lifetime and uptime of equipment are examined which improve the accuracy and suitability of problem for the practical.

Decision-Making on Working Capital Management, Based on Industry Differences

Research Article
Author(s): Haritini Tsangari
Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The effect of working capital components on profitability has conflicting empirical evidence, which is mostly data-driven. This paper aims to provide additional insight to this end, especially focusing on the neglected aspect of industry differentiation. The analysis implements a panel regression methodology on a dataset of 300 observations from firms in Cyprus, adjusting for control variables and considering industry differences. Overall, the present study illustrates that industry differences warrant in-depth examination for decision-making regarding working capital management policies. The findings show that the cash conversion cycle and its components have an effect on profitability, but the sign and level of significance vary according to the industry sector: results in the merged sample differ from the results by industry sector. For example, the cash conversion cycle has a positive effect on the consumer goods sector and a negative effect in the industrials sector. Additionally, management of creditors and suppliers is as important as the management of debtors, especially for consumer goods and industrials. Managers should aim for the optimal level of the working capital components, while simultaneously adjusting their strategies based on their industry sector, to boost firm profitability.
Contribution/ Originality
This study contributes to the existing literature regarding the effect of working capital management on profitability. The paper’s primary contribution is finding that the sign and level of the effect of the cash conversion cycle and its components on profitability vary according to the industry sector, which can thus adjust decision-making.

Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Evaluating service quality is a critical task for airports aiming to identify aspects of airport service that contribute to differences in passenger satisfaction. The purpose of this paper is to investigate the airport service quality from passengers’ perspectives at two airports (Pudong and Hongqiao Airports) under the management of Shanghai Airport Authority (SAA) in China. Surveys at SAA have found that there are significant differences between passengers’ expectations and actual perceptions of service quality at SAA, which imply that SAA is advised to improve its service quality and reduce passenger dissatisfaction towards components comprising service quality as a whole. The components for which the largest gaps were found between expectation and actual perception were identified as “Shop and restaurant prices”, “Free Wi-Fi access”, “Play areas for children”, “Departure punctuality”, and “Various restaurants providing different kinds of food”. The results reveal that there are significant differences between gender, nationality and main travel purpose groups: women tend to assign significantly higher scores than men; domestic travellers reported high satisfaction than international ones; and passengers travelling for holiday and academic-related purposes reported higher satisfaction than those travelling for business. There is a positive correlation between airport service quality and passengers’ overall satisfaction at SAA. This paper aims to provide useful information for government officials in the identification of potential issues posed to passengers and that should be addressed by airport management.
Contribution/ Originality
This study is the first attempt to investigate airport service quality from passenger’s perspective, rather than from airport’s perspective. The paper’s primary contribution is its findings in passenger’s perception and expectation according to different demographic groups, and their varying impact on passenger’s satisfaction and airport preferences in China.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
At the initial stages of starting a company, one who sets up the business and business deals is a start-up entrepreneur. This research focuses on entrepreneurs in start-up companies and explores how certain psychological needs influence motivation at the start-up stage. Basic Psychological Needs Theory is the latest and central theory from the SDT (Self-Determination Theory) (Deci and Ryan, 2000;2002). Jian et al. (2012) pointed out that psychological need is a critical factor in connecting the external environment and internal individuality. Additionally, entrepreneurial motivation is a precondition for entrepreneurship. Recent research suggests that motivation is an important role in entrepreneurial behavior and success where motivation has influenced entrepreneurs to start a business (Virginia and Carlos, 2012) . The research looks at the relationship between the psychological need and motivation of candidates of start-up in Singapore utilizing positivist approaches. Multiple regression analysis was used to analyze a causal relationship between psychological need and entrepreneurial motivation. Results found that there was a statistically significant relationship between two concepts.
Contribution/ Originality
The paper's primary contribution is finding that relationship between the basic psychological need and entrepreneur motivation in Singapore. Thinking about the causation of two concepts, this study has analyzed the impact of the psychology in the field of entrepreneurship.

Abstract
The focus of this study was to investigate “principals’ administrative competence and teachers work performance” in Calabar Education zone. Four null hypotheses were tested in the course of the study. Correlational research design was adopted, while purposive sampling technique was used in selecting a sample of 800 teachers. Two instruments were used for data collection including “Principals’ Administrative Competence Questionnaire (PACQ),” and Teachers’ Work Performance Questionnaire (TWPQ).” Pearson Product Moment Correlation Analysis (r) and multiple regression (R) analysis were employed to test the hypotheses at .05 level of significance were applicable, with the aid of SPSS v21. Findings from the study revealed that; principals’ supervisory, leadership and communication competences are significantly related to teachers’ work performance in terms of instructional delivery, attendance to classes, notes writing, and record keeping respectively. It was also revealed that; principals’ supervisory, leadership and communication competences have significant composite influence on teachers’ work performance in terms of instructional delivery (p < .05; F = 26.764), attendance to classes (p < .05; F = 109.122), notes writing (p < .05; F = 228.118), and record keeping (P < .05; F = 468.793). Based on these findings, it was recommended amongst others that; such techniques as close supervision of teachers, good leadership styles, and effective communication should be jointly practiced by secondary school principals in order to improve teachers’ work performance.
Contribution/ Originality
This paper contributes with the findings that; principals’ administrative competence in terms of supervision, leadership, and communication influence teachers work performance relatively and compositely, in terms of instructional delivery, attendance to classes, notes writing and record keeping.

Journal: International Journal of Public Policy and Administration Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Local authorities play an important role in the national development of any country as they are the vehicle for basic municipal service delivery. They are the interface of government and its citizenry at the local level meaning that local authorities represent government in action. As such, the same are expected to proffer sustainable services in the right amount and at the right time. Local authorities therefore provide the backbone for a country’s socio-economic development. However, the recent history of the local authority sector suggests that councils have fallen way behind in terms of delivering on their mandate due a number of factors. The Ministry responsible for Local Government in Zimbabwe notes that the peak year where councils were optimally functional was 1996 and this is the level that has been benchmarked. In the main, it may be noted, that councils in Zimbabwe rank among the most liquid organisations; their revenues are guaranteed in the Constitution and in some way in the relevant Acts of Parliament. As such, it is within the rights of the public to expect local authorities to offer more than they have done since the turn of the millennium. It may be argued that the set-up of local authorities in Zimbabwe is not aligned to the objective of delivering optimal services to communities with the same not responding to the demands of the people as well the operating environment. To significantly alter this negative spiral of performance, it is imperative that local authorities deal decisively with issues surrounding organisational culture in order to focus members (councillors and employees), policies and processes towards the achievement of both local and national goals and priorities. This study reviews the literature already proffered on the subject matter in conjunction with primary research to add to the body of knowledge in this area of study.
Contribution/ Originality
This study contributes to the existing literature in the field of organizational culture and service delivery in the public sector. Research has been carried out on the private sector’s organizational culture in developed countries. There is limited literature on organizational culture in the public sector in the developing world. The study used qualitative research methods that present a practical way of establishing the organisational culture’snorms, values and belief systems that can’t be measured quantitatively.

Abstract
This study evaluated the renal biofunction potentials of ethanolic extract of Solanum melongena Linn fruit on monosodium glutamate-intoxicated rats' and kidney histology using standard protocol. Twenty four Wistar rats that weighed 105.00 ± 7.00 g were used. The rats were assigned into 6 groups of 4 each and fed thus: Group 1 (control, feed and distilled water only), Group 2 (8000mg/kg body weight monosodium glutamate (MSG)), Group 3 (300mg/kg body weight (bw) the sample extract), Group 4 (8000mg/kg bw MSG + 100mg/kg bw the sample extract ), Group 5(8000mg/kg bw MSG+ 300mg/kg bw the sample extract) and Group 6 (8000mg/kg bw MSG+ 500mg/kg bw the sample extract) daily for 14 days. The results were expressed as mean ± S.E.M and one-way analysis of variance (ANOVA), followed by a Duncan posthoc test was done to test for significance using SPSS version 22.0. The exposure of MSG resulted in a significant (P =0.05) increase in the activities of serum urea, creatinine, potassium ion, chloride ion, and sodium ion compared to the control. MSG and ethanolic extract of Solanum melongena Linn fruit co-treated groups at different concentrations were significantly (P =0.05) reduced to become comparable to the control group. MSG consumption in high concentration alters renal biofunction and this is also evident in the histology of the studied rats' kidney sections. However, the protective roles of ethanolic extract of Solanum melongena Linn fruit were notably at 500mg/kg of body weight in rats, a pointer to the dose-dependent function.
Contribution/ Originality
This research underscores the possible MSG-intoxication effects on the renal system in high concentration be it inadvertently or not and as well as the possible ameliorative roles of Solanum melongena Linn fruit on the affected organ on a dose-dependent function.

Abstract
Different configurations for a hybrid energy system are presented. This study aims to produce 100 m3/day of freshwater for 120,000 people at Nakhl city, North Sinai, Egypt. This simulation selects the optimal design of the hybrid energy system according to the net present cost (NPC), the cost of energy (COE), the gases emissions (carbon dioxide, sulfur dioxide) and the excess system electricity. The hybrid system consists of photovoltaic panels, wind turbines, storage batteries, and a diesel generator. The operation of five different systems is studied to supply the load at an average rate of 557.22 kWh/day with 35.67 kW peak load. In order to minimize the system total cycle cost, both of the photovoltaic modules sizing, the wind turbine production, the number of battery strings and the diesel generator fuel consumption are studied. Homer Pro software is used to select the optimal system configuration. The results illustrate that the hybrid PV/diesel/RO desalination plant system with storage batteries is sustainable and socially accepted system. It consists of 83.5 kW PV panels, a 36.4 kW converter, seven strings of lead-acid batteries and a 50 kW fixed capacity generator. Also, the system achieves the lowest cost of energy and net present cost.
Contribution/ Originality
This study is one of very few studies which have investigated the optimal hybrid power system configuration to drive a reverse osmosis desalination plant at the Nakhl city, Egypt. This study documents that renewable energy is the effective option to face the fuel energy pollution by reducing the gases emissions from burning fossil fuels.

Abstract
The study determined the attitude of youths to agriculture as a career in Iwo and Aiyedire Local Government Areas of Osun State, Nigeria. The sample size of the study was 90 youths which were randomly selected from the clans of the study area. The questionnaire was the instrument used for data collection. Data were analysed with mean and t-test. Results showed that the attitude of youths to agriculture as career in the study area was negative as indicated by grand means of 2.44 and 2.47 in Iwo and Aiyedire respectively. The variable with the highest negative response in Iwo with a mean of 2.32 was that agriculture is a gold mine for young entrepreneurs. For Aiyedire the variable with the highest negative response of 2.42 was that agriculture is attractive and decent. The major constraints of the youths to the choice of agriculture as career in Iwo were insufficient land to start (3.02) and use of crude tools for farming (3.02). Lack of funds to begin (2.91) and insufficient career guidance by agricultural extension workers and rural sociologists (2.79) were the major constraints for youths in Aiyedire. In order to attract more youths into having a positive attitude to agriculture as career, the study recommends provision for sufficient land and fund for young farmers and engagement of more agricultural extension workers and rural sociologists for career guidance to youths in the study area.

Abstract
Due to the geographical proximity and popularity of Korean dramas in Mongolia, Mongolian trip to Korea is growing rapidly, especially in medical tourism such as plastic surgery, skin care, and general health care. Therefore, it is important to find what drives Mongolian consumers to choose Korea as a medical tourism destination. Based on the empirical findings of prior literature, it was hypothesized that medical tourism cost, medical service, medical technology, medical tourism accessibility, and tourism service are significant determinants to drive Mongolian medical tourism destination. In this study, we conducted a survey for choosing Korea as a medical tourism destination for 894 people living in Korea and Mongolia, age from 20s to 50s. For the analysis, we employed the multiple regression, and the findings suggest that medical technology, cost appropriateness, medical service, and tourism service have a significant influence on Mongolian choice of medical tourism in Korea, but medical tourism accessibility would not have a significant effect on medical tourism destination selection. Our study concludes with managerial implication and future research direction.
Contribution/ Originality
This study contributes to the existing literature by empirically testing the results of previous research on the determinants of medical tourism selection applied to Mongolian visit to Korea. The findings of this study have interesting managerial implications concerning marketing strategy, for both researchers and practitioners.

Abstract
The nature of relationship between deposit money banks loan to certain sector of the economy and its possible effect of reducing poverty rate in Nigeria is controversial and significant. As such, this study set out to examine the extent to which deposit money bank loan and advances to SMEs, agricultural, and manufacturing sectors in Nigeria has helped in reducing poverty rate. To achieve the objective of the study, unit root test, auto regressive distributive lag estimate and causality test were employed. Result shows that deposit money bank loan to SMEs and agricultural sector seem to be inversely related to poverty rate in Nigeria while sectoral allocation to the manufacturing sector is not capable of reducing poverty rate in Nigeria. This inherent relationship between loans to manufacturing sectors and poverty reduction in Nigeria could be attributed to some structural factors cited in the body of the paper. In the light of these findings, this study concluded that (i) Poverty rate in Nigeria is significantly sensitive to deposit money bank credit to agricultural sector; (ii) Within the context of the study, deposit money bank allocation to SMEs has helped in reducing poverty rate in Nigeria to the tune of 1.821 unit. On this premises, it is recommended that bank ordinances and financial institution act should be review to ensure that more credit is allocated to agricultural and SMEs sector as this will help in reducing the ever teaming trend of poverty in Nigeria through the window of job creation.
Contribution/ Originality
Having subjected our data set to rigorous analysis, it is established within the context of this study that sectoral allocation of deposit money banks loan and advances to small and medium scale enterprises has significantly contributed to economic growth such that poverty trend is being reduce to the tune of 1.82135 unit all things being equal. Further, deposit money bank allocation to the manufacturing sector does not seem to be significant in boosting economic output, as such poverty trends remain unchanged.

Abstract
This paper examined the roles of labour union in Nigeria industrial harmony and development. It notes that strong and united labour unions are pre-requisites to industrial and national development of any nation. Some objectives of trade unions such as negotiation, representative body, maintenance of employee-employer relationship, and promotion of member’s welfares were noted and discussed. The paper also observed that workers join union because of job security, need for adequate wages and benefits, power in group for collective bargaining and need to associate with others. Some challenges facing labour unions in Nigeria such as disunity, financial weakness, weak collective bargaining process and dishonest attitude of trade union leaders were identified. The paper concluded that disunity and politicization of trade union are major obstacles for the development of strong and stable trade unions which is an integral part of cordial industrial relations. In addition, a strong and enlightened labour union is vital for good industrial relations system and help to promote the interest of labour union. It is recommended, among others, that unions should identify current trend in industrial relations and educate their members to anticipate for the changes brought about by environmental forces affecting industries. Trade unions should create a level playing ground for all members to take part in the decision making machinery of their unions. Union members should ensure that only qualified, tested and trusted leaders who are truly workers should be voted into offices both at the local, state and national level. In addition, union leaders should be properly trained and educated to know the basic labour and industrial laws of the country in order to plan their actions within the provisions of the laws. Trade unions should also provide for the adequate training of their members in order to give room for advancement of their members.
Contribution/ Originality
This study contributed new knowledge to existing management literature. It examined the roles, objective and challenges of labour union in Nigeria. The primary contribution is finding that a united and proactive labour union is vital in maintaining a progressive and harmonious management-worker relationship which drives industrial harmony and development.

Abstract
The genotype environment interaction (GEI) has always been considered as an important issue by researchers involved in varietal selection and yield performance assessment. The objective of this study was to identify stable genotypes of cowpea in the Greater Kasai region. The current study was undertaken in 3 locations in the Ngandajika territory of Lomami Province (central part of Democratic Republic of Congo (DRC) with 12 improved cowpea genotypes obtained from the National Institute for Agricultural Research and Studies. The experiments were conducted following the randomized block design with 3 replicates and 12 treatments. Analysis of variance (ANOVA) and AMMI model were applied to identify main effects and GEI. The genotype yield stability across different locations was determined using the stability value of AMMI (ASV) rank of the AMMI model. ANOVA test indicated that there was performance inconsistencies in the yield of the 12 genotypes tried across the environments retained in this study. However, AMMI model revealed genotypes with stable yields across the different environment considered in the study. For the determination of the specificity of adaptability of genotypes to specific environments, the stability value of AMMI and diagram plot techniques were used for the discrimination of the genotypes versus the different environments considered. The genotypes Mujilanga (V2), CNGKASA7-2-M (V3) and CNGKASC2-1-1-T (V9) were identified as the most stable across different environments studied. Their yields were significantly higher (P<0.05) since they oscillated between 260 and 369 kg / ha as compared to the overall average of 312 kg / ha.
Contribution/ Originality
This study is one of very few studies which have investigated yield stability and adaptability of cowpea genotype in central part of DR Congo. The paper’s primary contribution is finding that stability value of AMMI (ASV) rank and diagram plot discriminated three cowpea genotypes for dissemination in central part of DR Congo.

Journal: International Journal of Sustainable Energy and Environmental Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This study assessed the effects of different contents of two refined phosphogypsums (PG1, PG2) on standard consistency, setting times, compressive strength and sulfate resistance of cement. PG2 possesses higher water-soluble impurities such as P2O5, F content than PG1. The results were compared to those of cement containing natural gypsum (NG). The results showed that water demand of cement reduces when the content of the gypsums increases, especially with PG1 and NG. The phosphogypsums prolong the setting times of cement. The higher the gypsum content is, the more the 3-d compressive strength of cement can obtains. The low impurity phosphogypsum (PG1) accelerates the 3-d strength but lowers the 91-d strength of cement compared to the high impurity phosphogypsum (PG2). The strength of cement containing NG is always between those of the phosphogypsums at the ages of 3 and 91 days. There is a suitable content of gypsum to produce the highest strength of the cement at the ages of 28 and 91 days. Deterioration of the cement in sodium sulfate solution (50g/l) is more severely when increasing gypsum content. The sulfate resistance of cement containing PG1 is lower than that of cement containing PG2 or NG.

Abstract
Recently, the expansion of information technologies and the exponential increase of the digital data have deepened more the security and confidentiality issues in computer networks. In the Big Data era information security has become the main direction of scientific research and Big Data analytics is considered being the main tool in the solution of information security issue. Anomaly detection is one of the main issues in data analysis and used widely for detecting network threats. The potential sources of outliers can be noise and errors, events, and malicious attacks on the network. In this work, a short review of network anomaly detection methods is given, is looked at related works. In the article, a more exact and simple multi-classifier model is proposed for anomaly detection in network traffic based on Big Data. Experiments have been performed on the NSL-KDD data set by using the Weka. The offered model has shown decent results in terms of anomaly detection accuracy.
Contribution/ Originality
This study proposed multi-classifier model for increasing anomaly detection accuracy in network traffic. The model consists of the J48, LogitBoost, IBk, AdaBoost, RandomTree classifiers. This work performed a comparative analysis of used classifiers and their combination to see which one will give the best result In study classifiers and their combination have been implemented on NSL-KDD open source dataset using WEKA tool. The results show that the ensemble classifiers provide the better result than using these classifiers individually. The computer network traffic analysis with employment of our model can help network engineers and administrators to create a more reliable network, avoid possible discharges and take precautionary measures.

Abstract
Most of developing countries such as Zimbabwe see foreign direct investment as a panacea for augmenting domestic savings, generating employment, eradicating poverty and stimulating economic growth. Foreign direct investment also is associated with significant positive spillover benefits such as; facilitating technological progress, enhancing production efficiencies, promoting skills and knowledge diffusion and increasing international competitiveness. The paper investigated the role of cost of capital, uncertainty, exports, market size and other macro factors in attracting FDI in Zimbabwe. This paper relied on a time series analysis using Ordinary Least Regression equation for the period 1998-2017. Uncertainty and cost of capital were found to be negative and statistically significant whilst market size and lagged exports were found to be positive and statistically significant. The paper recommends adoption of policies that improve domestic absorptive capacity such as the elimination of uncertainties in the economy, promoting more trade openness, improving market size and liberalisation of credit and financial markets to reduce firm borrowing costs.
Contribution/ Originality
This study contributes to the existing literature on foreign direct investment by demonstrating the role of macro-uncertainty and cost of capital in attracting FDI. In addition, this study utilizes a new estimation methodology of FDI that is based on the modification of the flexible accelerator model of investment behaviour.

Abstract
This study aims to spatially assess the flood vulnerability then suggests appropriate vulnerability lessening and adaptation mechanisms in Rwanda. Six vulnerability factors namely the rainfall and temperature, total population, access to communication tools, poverty level and number of schools were analyzed. The Weighting Linear Combination (WLC) method in ArcGIS is used to analyze these factors and spread the resulting flood vulnerability countrywide. The results showed high flood vulnerability within the northern, western and southern provinces and Kigali city of Rwanda. This vulnerability is likely to rise due to the noticed low possession of communication tools and education delivery, which could help to enhance the risk awareness and preparedness among the vulnerable communities. The results of this study can help policy makers to understand the required community’s vulnerability lessening measures and ensure spread of mitigation and adaptation policies as per vulnerability extent within Rwanda.
Contribution/ Originality
The paper primary contribution is finding that climate change risk, mainly the flooding are gradually causing severe losses and damages in Rwanda. Thus, the mapped flood vulnerability can be useful to policy makers to better recognize the required vulnerability lessening policies based on the actual circumstances.

Abstract
This study focuses on impacts of deregulation policy of interest rate on the profitability of commercial bank, which will create competition among conventional financial institution for their traditional activities of banks (Deposits, loans and other financial institutions activities). The demand and supply will increase to encourage fund mobilization based on interest rate. Sanity becomes significant in the financial institution as utilization of fund is been judiciously encouraged and invests it to the most profitable ventures. The study explored the survey questionnaire by selecting five financial institutions and distributes twenty (20) questionnaires for each financial institution to their respective managers (experts) for their input. The simple description analysis and correlation were considered for variables comparison to achieve the research objectives. The research findings indicate that the deregulation significantly contributed to the profitability of commercial financial institution and promote competition among their counterpart. The study also reveals that the deregulation in interest rate leads to an increase in profit maximization. The study recommended the changes in the discount rate will reflect a stipulated range depending on how monetary policy pursued and the relation of a current market economy with interest rate, the sufficient control of the institutions and regulatory bodies to ensure the forces driving the economy as adequately managed and controlled.
Contribution/ Originality
This study contributes to the existing literature on the interest rate deregulation. The study uses a new estimation methodology as a structural survey questionnaire which used correlation and descriptive analyses. The study is one of the very few studies based on deregulation of the interest rate on commercial bank.
