Extant literature has extensively explored microcredit's impacts, confirming its essential role in poverty alleviation. However, most studies focus on poverty measures that exclusively emphasize current poverty status without adequately addressing the potential of falling into or remaining in poverty. Furthermore, the role of credit services in helping the poor in rural areas appears to be underexamined in the literature. To address this knowledge gap, this study investigates whether rural microcredit can reduce household vulnerability to poverty. A theoretical framework is developed to capture the mechanism by which microcredit borrowing has a vital role in household businesses and impacts the probability of being poor in the future. The Vietnam Access to Resources Household Survey data set from 2008 to 2016 is used to explore this issue. The findings indicate that rural Vietnam's access to microcredit significantly reduces vulnerability to poverty. Moreover, better‐off households are seemingly the most effective at using microcredit, whereas the opposite is found among worse‐off households. These results are found to be robust using the propensity score matching method.

Purpose: This paper explores the relationship between board interlocks and firm outcomes by reviewing the most recent peer-reviewed articles examining this research theme.Design/methodology/approach: A systematic and bibliometric methodology of assessing 369 peer-reviewed articles from the Web of Science (WoS) database was applied. The study also leverages key R-packages litsearchr and Bibliometrix software to enhance the descriptive and thematic literature analysis to identify gaps and opportunities for new research.Findings: This study confirms a rapid increase in articles on this thematic area, over the last decade, with increasing collaboration occurring among researchers in the United States, Europe, China, South Korea and India. Four core research clusters are identified. The first and largest cluster links interlocked directors to issues related to corporate governance and firm outcomes. The second cluster links social network theory, interlocking directorates and firm outcomes. Smaller emerging research clusters include topics related to ownership structure, board size, political connectedness and impacts on firm outcomes. The final cluster examines the influence of board interlocks on market value and firm innovation.Practical implications: Interlocked directors can have both positive and negative impacts on a wide variety of firm outcomes. This study places great interest in the selection of new directors, ensuring that the selection has aligned with the needs and interests of the company and disclosures of potential competing interests are declared and considered. Equally important are the governance practices used to monitor directors' behavior and to protect the interest of shareholders and the firm. This is particularly relevant in the internal appointment of interlocked directors to critical positions, such as audit committees or instances where interlocked directors may simultaneously hold CEO or executive leadership positions in other companies.Originality/value: This paper examines the board interlocks literature related to firm outcomes. Additionally, this review identifies several topics and disciplines which, if pursued, could enrich the literature and promise new avenues for future research.

Although microcredit targets both financial and, more importantly, social returns, it is unclear in existing literature that whether participating in microcredit programs fosters social network. Filling this gap, this study aims to quantitatively test whether microcredit improves the social network of rural households in Vietnam. Specifically, with microcredit borrowing to fund its family business, a representative household is engaged in a two-stage decision problem, namely to first choose a social network and then consumption to maximise its lifetime utility. Utility maximisation yields an optimal social network as a function of microcredit borrowing, which is estimated using the VARHS dataset from 2008 to 2016 in Vietnam. We find that microcredit improves both rural household’s social network quality and size.
