After reading this case study, the students will be able to identify the various choices available in social e-commerce using network marketing, interpret data-driven decisions in social e-commerce and evaluate their role in scaling business, analyse cost and revenue management in value segments, evaluate technology adoption among the masses using appropriate communication structures and develop customer relationships and manage their sentiments in the era of social media.

DealShare became a unicorn in 2022 and targeted the rural and low-income groups. Based on a networking model for customer acquisition and a hyperlocal supply chain model, DealShare is increasing its customer base at a rapid pace. However, profitability was still a challenge, and converting high volume into high value continued to be a daunting task. This case study delves deep into the challenges co-founder Sourjyendu Medda and the DealShare team faced. It seeks to address key issues: how should DealShare leverage customer network for faster customer acquisition and how should they increase ticket size and profitability? As a data-driven business, what advantages does DealShare have in influencing customers’ buying behaviour using data? Dependence on social media could have a cascading effect on “word of mouth”. How can they manage customer complaints and increase engagement?

Purpose: This chapter aims to evaluate the impact of money laundering and terrorism financing on the Indian economy and to study the effectiveness of prevention of money laundering acts and terrorist financing as per the guidance of the financial protection task force.

Need for the study: Developing countries like India have been more vulnerable to terrorism and financial scams over the last four decades. Despite the establishment of regulating bodies and anti-money laundering acts, this problem continued to be a national threat. Therefore, examining the impact of money laundering and terrorism finance on the Indian economy is necessary.

Methodology: This study is based on secondary data gathered from the web portals of government agencies and international organisations dealing with money laundering and terror funding. Newspapers, journals, and annual reports are reviewed to identify the modus operandi of money laundering operators and their impact on the economy.

Findings: Money laundering and terrorism financing significantly threaten the Indian economy and national security. Despite different anti-money laundering laws and multiple regulating authorities, the system has pitfalls that allow economic fraud and money transactions for terrorist activities. There is a need for cyber security, and integrated enforcement agencies to combat money laundering at national and international levels.

Practical implications: This study would be helpful for academicians and policymakers to understand the nexus of money laundering and terrorism financing and its impacts on the Indian economy.

The purpose of this paper is to investigate the relationship between total productive maintenance (TPM) practices and operational performance (OP) in soft drinks manufacturing industry, Ethiopia.

In this study acceptability and implementation of five TPM practices (i.e., dependent factors: autonomous maintenance (AUT); safety, health and environment (SHE); education and training (EDT); focused improvement; and planned maintenance (PLM)) in soft drinks manufacturing industry have been elaborated to ascertain the benefits accrued as a result of successful TPM practices (i.e., independent variables) on OP (i.e., dependent variables). A self-administered survey seven-point Likert scale questionnaire was used for primary data collection. By using simple random sampling technique a total of 100 useable responses resulted in a 66.66 per cent response rate. Descriptive (mean, standard deviation) and inferential statistics (factor analysis, correlation, simple and multiple regression analysis) analysis were performed using Statistical Package for Social Sciences (SPSS) software (version-28) to identify the relationship and effect of TPM practices on OP. Five hypotheses were developed and tested.

Results show that four of the TPM practices were positively and significantly correlated with OP. Aggregate TPM shows positive and significant correlation with OP. Four hypotheses results revealed that the AUT; SHE; EDT and PLM practices have positive and significant relationship with OP and significantly improve OP. The results also show that the TPM practices have positive and significant relationship with OP and significantly improve cost effectiveness, product quality, on-time delivery and volume flexibility.

The benefits gained by TPM practices in selected soft drinks manufacturing industry have been highlighted, that could be genuine source of motivation to other companies to go in for TPM program. This research contributes to the literature by examining the contingency of various TPM enabling factors in the context of the Ethiopian soft drinks manufacturing sector, and it, therefore, provides direction to increase the success rate of TPM implementation. Study offers academics and practitioners a better understanding of the relationship and effect of the TPM practices on the OPs. Thus, practitioners will be able to make better and more effective decisions about the implementation of TPM practices for better OP results.

The relationship between the five factors TPM practices and OP has not yet been studied or reported in the case of soft drink manufacturing industry. The questionnaire manner and items developed, factor considered in this study, sampling method, deeply statistical data analysis techniques used, soft drink manufacturing industry, developing country like Ethiopia make this study unique and revealed the gap identification in this area. The study has contributed to the TPM literature with a better understanding of the five TPM practices and their association with a soft drink manufacturing industry OP that will provide valuable knowledge to top-management of manufacturing companies, to refine their current TPM practices and subsequently improve OP.

In the post-Enron era around the world, the role of auditor is widely debated. There is an increasing concern that an auditor’s continuous involvement with clients could impair audit quality – the negative view. There is also a positive view that a long auditor tenure leads to accumulation of client-specific knowledge over time, which could lead to high-quality audits. The empirical result with regards to impact of mandatory auditor rotation (MAR) is mixed world-wide. This study aims to examine whether MAR rules implemented in 2017 impact audit quality in India.

Using a unique setting in which MAR was required from 2017 to 2018 onwards in India, this study provides empirical evidence of the impact of MAR regulation on audit quality (modified audit opinion). The study uses data for 714 firms (4,284 firms) for six years (three years before MAR and three years after MAR regulation in India).

The study found that auditor tenure and MAR had significant negative impacts on audit quality, validating the “positive” view of audit tenure and audit quality. In addition, concentrated ownership had a negative impact on audit quality, implying the control and influence by concentrated ownership on auditors and audit opinion. The analysis shows that MAR regulation has not yielded the intended objective of improving audit quality in India. MAR is not a good template for improving audit quality.

The findings of the study are useful to policymakers, regulators, managers, investors and users of financial reports. The study calls for public policy on auditor rotation based on objective scientific evidence. In light of the evidence in India that MAR does not lead to better audit quality, the study calls for reset of regulatory policy in India.

The study provides valuable insights to analysts, regulators and other users of financial accounts about the implications of MAR in India.

The study is one of the few to report on the impact of MAR, particularly in the context of an emerging market economy such as India.

The case study aims to provide students with an understanding of the challenges a business faces when operating in India. In conclusion of this study, students should be able to know why franchising is such a common way of delivering services to end users, describe the “place” decisions of physical channels, and be familiar with the strategic and tactical location considerations and devise a growth strategy to expand the business.

Situated at Tito’s Lane in North Goa, Tito’s was the discotheque founded by Tito Henry D’Souza in 1971. The company offered restaurant, concert space and nightclub services to music and party lovers from diverse locations. Ricardo D’Souza and David D’Souza (both brothers) spearheaded the business. Ricardo understood the growth of markets and the factors driving the growth in India. The key factors driving the Tito’s and pub, bar, café and lounge business in India were rising disposable incomes among Indians, nightlife parties by young individuals and preference for quality food and alcoholic beverages among the customers. By seeing the opportunities in 2022, Ricardo considered expanding its business across India. How should Ricardo move to expand its business and offerings? What strategies should they devise for the growth of the business?

This case study is designed for use in undergraduate programs like Bachelor of Business Administration. It is ideal for strategy and services marketing. Theoretical frameworks like the Ansoff matrix are suitable for analyzing the case study to understand the growth of the business.

This paper aims to analyse the factors influencing migration, the labour migration process and the status of migrant laborers in the informal sector, particularly those working in brick kiln factories. It will shed light on the precarious nature of their work, often characterized by informal and verbal contracts. The paper examines occupational and environmental health hazards affecting the labourers and their impact on their well-being, the vulnerability of women in the precarious work environment and the associated health risks in brick kiln factories in India.

The study relies primarily on primary data collection, supplemented by secondary literature and documents. Balangir district was chosen as the research region due to its historical deprivation, underdevelopment and the historical prevalence of environmental distress, leading to distress-driven migration. To gather primary data, 40 respondents were selected from five selected blocks in Balangir district, resulting in a total of 200 respondents. In addition, in-depth interviews were conducted with 35 individuals across the selected blocks, with approximately seven participants from each block. In addition, interviews of 10 kids were taken and around 10 key informants including the trade union leaders, intellectuals and civil society activists.

Migrant labourers, including men, women and children, face significant health issues and are exposed to similar occupational health hazards. Internal migrant women workers are more vulnerable as they face critical health risks during pregnancy in host areas due to unfavourable working conditions and limited access to health-care services. Factors such as strenuous work, long working hours, poor nutrition and inadequate maternal care contribute to adverse outcomes such as spontaneous abortion, premature delivery and abnormal postnatal development.

The brick kiln industry presents a distressing reality for men who are highly vulnerable to occupational accidents, and women workers are exposed to sexual abuse, exploitation and violence. The prevalence of physical harassment, ranging from leering to rape, is alarmingly high among women. These incidents not only inflict physical harm but also cause severe psychological trauma and increase the risk of sexually transmitted diseases. Despite the existence of laws aimed at protecting women’s rights and addressing sexual offences, the workers often remain unaware of their rights. This lack of awareness further compounds the vulnerability of women workers and perpetuates their exploitation in the workplace.

To address health issues comprehensively, interventions should encompass the entire migrant population, including men and children. Strategies should focus on improving access to health-care services, promoting occupational health and safety measures, ensuring proper immunization and nutrition for children and addressing the broader social determinants of health. Empowering women with knowledge about reproductive health and rights, raising awareness about available health-care services and strengthening health-care providers’ capacity to cater to migrant populations are crucial steps towards addressing health disparities.

Urgent interventions and policies are needed to address the health vulnerabilities of internal migrant workers and women workers. It is required to ensure health-care accessibility, improving working conditions, ensuring access to maternal care and essential supplements and providing health-care services for both pregnant women and their children, regardless of migration status.

The study focused on precarious health and occupational hazards and accidents faced by migrant workers. It highlights women migrant labourer’s and children’s vulnerability in the Brick Klin sector, which is a value addition to the existing knowledge in social science.
