  • Impact of big data analytics capabilities on supply chain sustainability. A case study of Iran

    Purpose: The purpose of this paper is to develop a theoretical model to explain the impact of big data analytics capabilities (BDAC) on company’s supply chain sustainability (CSCS). The secondary objective of the study is to assess the relationship between different dimensions of supply chain sustainability and companies’ BDAC. Design/methodology/approach: This research was carried out by conducting a survey among 234 pharmaceutical companies in Iran (a case study of Iran), using a standard questionnaire of BDAC and United Nations (UN) online self-assessment on supply chain sustainability. However, the respond of managers of 188 companies were usable in this research. Smart PLS3 was used to employ partial least squares method to examine the validity and reliability of the measurement and structural model. Findings: The results of this study demonstrate that BDAC have a strong impact on both pharmaceutical supply chain sustainability, and the dimensions including vision, engage and internal. It is found that the relationships between BDAC and the other dimensions of supply chain sustainability including expect, scope and goals are not significant but positive. Research limitations/implications: Research on the relationship between BDAC and CSCS, especially in the pharmaceutical supply chain, is scanty, and this gap is highlighted in developing countries and the pharmaceutical supply chain that plays a prominent role in public health. This paper discusses several important barriers to forming a sustainable supply chain and strong BDA capabilities. Practical implications: This paper could be a guide to managers and consultants who are involved in big data analytics and sustainable development. Since UN urges companies do the online self-assessment, the results of this paper would be attractive and useful for UN global compact specialists. Originality/value: No study has directly measured the relation between BDAC and CSCS and different dimensions of CSCS, using a comprehensive survey throughout all pharmaceutical companies in Iran. Moreover, this research assesses the different dimensions of BDA capabilities and supply chain sustainability. This paper represents the facts about situation of sustainability of pharmaceutical supply chain and BDAC in these companies, and discloses several related issues that are serious barriers to forming a sustainable supply chain and strong BDAC. In addition, this paper provided academic support for UN questionnaire about CSCS and used it in the survey.

  • The collaborative roles of the government and private sector to foster innovation in Bahrain

    Purpose: The purpose of this paper is to explore the government and private sector collaboration by focusing on their roles in influencing the innovation activities crucial for the development of a knowledge economy (KE) in Bahrain. Design/methodology/approach: A qualitative methodology based on an explorative single multi-unit case study strategy was used with individual and focus group interviews as primary sources of data collection. Perspectives of 22 individuals and three focus groups involving participants working in private, semi-government and government sectors that influence the economy of Bahrain were collected along with reports and articles published regarding those sectors as second sources of data compilation. Findings: The preliminary findings show that Bahrain’s pursuit of a KE has already begun by the government developing policies and regulations for the financial sector to innovate in financial technology (FinTech). It was also found that in order for innovation processes and products to be developed further in Bahrain, the government had to play a stronger role in promoting, facilitating and incentivizing those processes and developments. The role of the private sector emerged as the sole producer of innovation and the main entity responsible for producing innovative products and services that would inject direct values into the commercial economy of the innovation ecosystem. Originality/value: This is the first study that examines the influence of collaboration between the government and the private sector on innovation development in Bahrain. This research also provides an assessment tool that can serve as the groundwork for studies in the Gulf Cooperative Council countries since those countries share similar culture, language, religion and a hydrocarbon-dependent economy as Bahrain and are aiming to develop KE strategies.

  • Household demand for basic foodstuffs in a recessed economy: a case study of Southwest Nigeria

    Purpose: The economic recession that Nigeria recently passed through caused distortions in economic and well-being of Nigerians. The purpose of this paper is to examine the effects of the economic recession on households’ demand for basic foodstuffs in Southwest Nigeria. Design/methodology/approach: Data were collected from 380 respondents drawn from urban areas of Lagos, Osun and Oyo states using multistage sampling technique. Descriptive statistics and Quadratic Almost Ideal Demand System were employed to analyze data collected. Findings: The study showed sharp increase in the prices of basic foodstuffs during recession. Households were compelled to spend higher percentage of their monthly income on basic foodstuffs. Also, 51.1 percent of the respondents were government workers who experienced inconsistent or modulated monthly salary during the period. The percentage of households that were food insecure was 36.4 percent. Osun State had the highest monthly per capita expenditure (₦5,147.13) on foodstuffs, followed by Lagos and Oyo states while rice had the highest expenditure share (0.26), followed by yam (0.18), beans (0.106), vegetable oil (0.104) and garri (0.101). The breakdown also showed that 11.7, 18.1 and 17.7 percent of the total household monthly expenditures in Lagos, Osun and Oyo states, respectively, were spent on basic foodstuffs. Research limitations/implications: There purchasing power of naira reduced significantly during recession, thus compelled households to spend more on basic foodstuffs compared to similar purchases before economic recession. Practical implications: The reduction in purchasing power of naira affected the formal and informal sector. Irregular salary for civil servants reduced their expenditure on goods and services. Originality/value: The study is original and topical, serving as literature of accounts that transpired among the households as far as demand for basic foodstuffs is concerned during the economic recession.
