Öğe Antecedents of customer loyalty in mobile telecommunication companies in Cameroon(Sage Publications Ltd, 2023) Tarkang, Mary Magdaline Enow Mbi; Yunji, Ruth N.; Asongu, Simplice; Alola, Uju VioletThe mobile telecommunication (telecom) sector has become the basic source of information nowadays, especially in Cameroon. It is used to transfer and deliver information through voice, video, data, graphics, and more at perpetually increasing speeds. The quality of mobile services does not only impact the attraction of new customers but also to maintain the existing ones. The study uses relationship marketing theory and a quantitative and cross-sectional method with 200 respondents. Information was obtained from users of MTN and Orange mobile telecommunication networks. The analyses were done using SPSS version 20. Tangibility, reliability, and assurance dimensions of staff service quality showed a positive relationship with customer loyalty in mobile telecom companies in Cameroon. The findings also highlight the influence of service quality dimensions on customer loyalty in the mobile telecom companies of the country.Öğe An empirical retrospect of the impacts of government expenditures on economic growth: new evidence from the Nigerian economy(Springer, 2020) Onifade, Stephen Taiwo; Çevik, Savaş; Erdoğan, Savaş; Asongu, Simplice; Bekun, Festus VictorThe impacts of public expenditures on economic growth have been revisited in this paper with respect to capital expenditure, recurrent expenditure and the government fiscal expansion in line with support for the budgetary allocations to various sectors in the context of the Nigerian economy. Pesaran’s ARDL approach has been applied to carry out the impact analysis using annual time-series data from 1981 to 2017. Empirical findings support the existence of a level relationship between public spending indicators and economic growth in Nigeria. Incisively, recurrent expenditures of government were found to be significantly impacting on economic growth in a negative way while the positive impacts of public capital expenditures were not significant to economic growth over the period of the study. Further results from the Granger Causality Test reveal that fiscal expansion of the government that is hinged on debt financing is strongly granger causing public expenditures and domestic investment with the latter also Granger causing real growth in the economy. We, therefore, provide some important policy recommendations following the results of the empirical analysis. © 2020, The Author(s).Öğe Linking supervisor incivility with job embeddedness and cynicism: The mediating role of employee self-efficacy(GADJAH MADA UNIV, MASTER MANAGEMENT PROGRAM, FAC ECONOMICS & BUSINESS, JALAN PANCASILA,, YOGYAKARTA, 55281, INDONESIA, 2019) Alola, Uju Violet; Asongu, Simplice; Alola, Andrew AdewaleApplying the conservation of resource resources theory and the self-efficacy theory, this study investigates the relationship between supervisor incivility, self-efficacy, cynicism and the job embeddedness of employees in the hotel industry. The role of self-efficacy, as an important variable that mediates the relationship between the predictor and the criterion variable, is significantly evaluated. A non-probability sampling technique was used to collect 245 questionnaires from frontline employees of five and four-star hotels in Nigeria. The findings reveal that supervisor incivility has a negative effect on self-efficacy and a positive effect on cynicism, and that self-efficacy negatively affects cynicism. There was no significant relationship with job embeddedness in the study. Importantly, the investigation establishes that self-efficacy is a mediating variable between supervisor incivility and cynicism. The study noted the importance of adopting a policy that introduces periodic seminars and professional training for both employees and supervisors, as a means for curbing incivility and cynicism. The study concludes with theoretical and practical implications, leaving room for further investigation.Öğe Revisiting the trade and unemployment nexus: Empirical evidence from the Nigerian economy(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2020) Onifade, Stephen Taiwo; Ay, Ahmet; Asongu, Simplice; Bekun, Festus VictorThe recent exacerbation of unemployment crisis in Nigeria stands to be a serious threat to both socio-economic stability and progress of the country just as the report from the Bureau of Statistics shows that at least over 8.5 million people had no gainful employment at all as at the last quarter of the year 2017. It is on the above premise, that the present study explores the link between trade and unemployment for the case of Nigeria with the intention of exploring how the unemployment crisis has been impacted within the dynamics of the country's trade performance. The empirical evidence shows that the nation's terms of trade were insignificant to unemployment rate, while trade openness and domestic investment, on the other hand, have significant opposing impacts on unemployment in Nigeria over the period of the study. Further breakdowns from the empirical analysis also revealed that the Philips curves proposition is valid within the Nigerian economic context, while the evidences for the validity of Okun's law only exist in the short-run scenario. Based on the empirical results, we recommend that concerted effort should be geared toward stimulating domestic investment by providing adequate financial and infrastructural facilities that will promote ease of doing business while utmost precautions are taken to ensure that unemployment crisis is not exacerbated when combating inflation in the economy in the wake of dynamic trade relations.
