Despite that reviews have been done in intellectual capital and the performance of firms, their status has remained uncertain in the emerging economy. Previous studies have generally focused on single industries and have overlooked the input of the service and manufacturing sectors as a whole. This study offers new insight into the area of intellectual capital and its relationship with firms' performance in Tanzania and evaluates intellectual capital within the service and manufacturing sectors in totality. Using panel regression analysis for the periods of 2010 to 2019, the performance was measured in terms of SG, ROA, ATO, and Tobin's. Heteroscedasticity and endogeneity were controlled using clustered robust standard errors. The empirical findings demonstrate a significant positive influence between structural capital efficiency and SG, ROA, ATO, and Tobin's. However, the effect of human capital efficiency and capital employed efficiency were negative which suggests poor investment in human skills and capital of the firms. Further, VAIC was significantly positively associated with SG, ATO, ROA, and Tobin's Q. It is recommended that to have a competitive advantage, managers and policymakers should focus on the three parts of intellectual capital which are the key drivers of value creation in the organization.

Purpose This study aims to examine the association between relationship quality, service quality, customer satisfaction, switching barriers and Islamic banking customer loyalty using evidence from Tanzania. Design/methodology/approach This study used correlational research design to test the hypotheses. Completed questionnaires were received from 572 Islamic bank customers in three major cities of Tanzania (Dar es Salaam, Dodoma and Zanzibar). Findings There is a significant positive relationship between relationship quality, service quality, customer satisfaction and customer loyalty. Switching barriers have an insignificant effect on customer loyalty. Further, the four antecedents contribute differentially to customer loyalty, with service quality having the most significant contribution. Practical implications The findings of the study can help managers of Islamic banks build and maintain customer loyalty through high service quality, high customer satisfaction and high-quality bank–customer relationships and attain a competitive advantage that would enable Islamic banks to grow and succeed in a competitive banking environment. Originality/value This study provides new insights on Islamic banking consumer loyalty by comparing the levels of contributions of the customer loyalty antecedents in a single study. This knowledge would enable Islamic banks to identify antecedents that have the highest contribution to customer loyalty and where best to target marketing attention and limited corporate resources.

Purpose The purpose of this study is to investigate the moderation effects of religiosity in the relationship between service quality (SQ), customer satisfaction (CS), relationship quality (RQ) and Islamic banking (IB) loyalty in a non-Islamic country. Design/methodology/approach This study used a quantitative approach and a cross-sectional research design. The data was collected by a closed-ended questionnaire from a systematic sample of 267 customers of full-fledged Islamic banks in Tanzania. Structural equation modeling and regression analysis techniques were used to analyze the data. Findings Results indicate that religiosity is a significant (p < 0.05) moderator of the relationship between SQ and loyalty (β = 0.176), and between CS and loyalty (β = 0.263). However, religiosity sharpens the impact of CS on loyalty (β increases from 0.170 to 0.263, p < 0.05) and does not sharpen the impact of SQ on loyalty (β decreases from 0.338 to 0.176, p < 0.05). The results further indicate that religiosity is not a significant moderator (p > 0.05) in the link between RQ and loyalty (β = −0.112). Research limitations/implications This study used only full-fledged Islamic banks in Tanzania. Therefore, future research could be undertaken by including conventional banks that have introduced an IB window. Practical implications To build and maintain a loyal customer base, Islamic banks should take advantage of religiosity by providing a wide range of Sharia-based products and services that truly distinguish them from conventional banks. Accordingly, policymakers should establish an appropriate legal framework to enable Islamic banks to leverage religiosity to sharpen the impact of CS on loyalty and hence maintain loyalty in non-Islamic countries like Tanzania. Originality/value This study proposes and validates the theoretical model of loyalty in IB by showing the role of religiosity as a moderator in a non-Islamic country. This knowledge strengthens the overall understanding of loyalty in IB. To the best of the authors’ knowledge, this study is the first to examine the moderation effects of religiosity in the link between RQ and loyalty, and thus between SQ, CS, RQ and loyalty in a single study.

PurposeThe purpose of this research is to examine the effect of heuristic biases on investment decisions through multiple mediation mechanisms of risk tolerance and financial literacy in the Tanzanian stock market.Design/methodology/approachA sample of 316 individual investors in the Tanzanian stock market was obtained through questionnaires. The data were analyzed using structural equation modeling (SEM).FindingsThe findings show that financial literacy mediates insignificantly the effects of overconfidence, availability, anchoring and representativeness heuristics on investment decisions. Further, financial literacy does not influence the effect of risk tolerance and investment decisions. Risk tolerance is confirmed as a positive mediator of overconfidence, availability, anchoring and representativeness heuristics in investment decisions. Also, the study shows that overconfidence exerts a stronger influence on investment decisions, followed by availability, representativeness, risk tolerance, anchoring and financial literacy.Research limitations/implicationsThe study deals with real investors. Therefore, it uses fewer items to measure the constructs in order to avoid respondent bias. Further research could examine the effects of heuristic biases on investment decisions by adding or modifying the items of particular constructs and studying institutional investors.Practical implicationsThe findings can help individual investors to analyze and evaluate their behavior toward stock selection. Securities institutions can use this research to understand investors' behavior, evaluate future market trends and provide advice to the investors.Originality/valuePrevious studies have examined the impact of heuristics on the investment decisions of individual investors. The unique empirical analysis developed in this paper is that it examines the multiple mediation mechanisms of risk tolerance and financial literacy with respect to heuristic biases and investment decisions in the Tanzanian stock market.
