Ten years of data from an Ecuadorian microfinance entity together with data on macroeconomic variables was analyzed. Through a Vector Autoregressive Model, we established a one-way causal relationship between credit and liquidity risks. The model includes the feedback effects through successive deterioration of credit portfolio and illiquidity spreading and the effects of macroeconomics and financial variables on these risks. Our results corroborate the importance of incorporating new contagion channels in microfinance institutions’ risk management, which helps microfinance institutions become financially sustainable, generating a relatively stable level of profitability that can improve the entrepreneur’s economic situation.

The interconnection between income inequality and entrepreneurship in African economies is examined. The study provides answers to two critical questions: (1) Does income inequality affect entrepreneurship? and (2) What is the implication of entrepreneurship for income disparity in Africa? With the Gini coefficient used as a proxy for income inequality, data from 23 selected African countries over the period 2006-2018 are analyzed. The analysis is based on panel data econometrics, and reveals that income inequality increases entrepreneurship in Africa. It is also discovered that entrepreneurship reduces income inequality. These findings persist after utilizing the Palma ratio as an alternative proxy for income disparity in African economies. In terms of policy implications, the study shows that income disparities serve as a push factor toward entrepreneurial activities. Entrepreneurship may serve as a veritable tool for policies aiming at reducing income inequality in Africa.

The paper empirically examines how gender affects international market engagement through its effects on entrepreneurial exit experience and innovation in early-stage social service ventures across different countries. Empirical findings from generalized linear mixed models with SAS GLIMMIX procedures support the direct effect of gender on international market engagement and the indirect effect of gender on international market engagement through entrepreneurial exit experience and innovation in early-stage social service ventures. The study shows significant gender gaps in the international market engagement of early-stage social service ventures owned by male and female entrepreneurs. The gaps appear to be rooted in gender differences in experiential learning resulting from entrepreneurial exit experience and innovation. The paper calls on governments to build gender-aware ecosystems that engage female entrepreneurs in experiential learning and innovation, thereby empowering them to grow through active international market engagement in early-stage social service ventures.

Enlisting entrepreneurship policies to address the twin issues of poverty and income inequality in particular, and development in general, has become a standard practice in low-income and less developed countries. Nigeria, Africa’s most populous country, is quintessential in this respect. This study investigates the extent to which entrepreneurship education has reduced both poverty and income inequality among entrepreneurs in South Western Nigeria. The study sample consists of tertiary institution graduates who undertook mandatory entrepreneurship coursework and then operated as micro, small and medium enterprise owners post-graduation. Data analysis reveals weak relationships between entrepreneurship education and both poverty reduction and income inequality, and a marginal effect of entrepreneurship education on the incidence of poverty, depth of poverty and severity of poverty. The study explores factors responsible for these results and makes recommendations on how to enhance the effect of entrepreneurship education.

The existing literature is filled with mixed findings on the effect of entrepreneurship on economic growth. In particular, previous literature treats the effect of entrepreneurship on economic growth in isolation, while we emphasize the institutional environment, and especially, economic freedom. Using data from the Global Entrepreneurship Monitor, we re-explore the relationship between entrepreneurship and growth and attempt to clarify the mixed findings. The systemic link between economic freedom, entrepreneurship and economic growth is investigated by examining a panel of 54 countries (2008-2018). The results validate that overall economic freedom and its subcomponents, such as the rule of law, limited government size, regulatory efficiency and market openness promote the positive effects of entrepreneurial activity on economic growth. The results suggest that economic freedom not only directs individual efforts to entrepreneurial activity, but also affects the extent to which entrepreneurial activity encourages higher growth rates. The findings contradict policy recommendations that some measures of economic freedom are not significantly associated with entrepreneurship.

While the aggregate positive effects of entrepreneurship are assumed in many studies, there is a lack of empirical support for such assumptions. This study investigates the causal relationship between entrepreneurship, economic growth and unemployment. We also examine how a shock in one variable may influence other variables and the length of the effect. The findings of panel data from 39 countries collected between 2006 and 2016 using the Granger-causality test indicate a unidirectional causal effect of economic growth on entrepreneurship and unemployment. However, despite their correlation, no causal link was found between entrepreneurship and unemployment. The analysis of impulse-response functions also shows that only shocks from the entrepreneurship indicator are permanent in the model. Variance decomposition results reveal that the most important factor causing changes in entrepreneurship is the entrepreneurship indicator itself, implying that only specific entrepreneurial policies can affect the entrepreneurship indicator’s components and improve this indicator.

We studied individual psychological characteristics such as conformity and ecocentrism in Mexican artisans, and the effect these characteristics have on entrepreneurial orientation (EO) and environmental behavior (EB) in artisan family businesses in Oaxaca and Guanajuato, Mexico. The research model is empirically validated by partial least squares structural equation modelling (PLS-SEM). We found that conformity is a value that positively affects EO and EB. In contrast, ecocentrism has a positive effect on EB, but not on EO. Our study highlights the importance of focusing on conformity as a characteristic of survival ventures. On the other hand, it is imperative to carry out research that incorporates the environmental dimension to characterize the sustainability aspect in survival ventures.

Drawing on insights from the family business succession and mentoring literature ,we examined the preparation process for daughters as successors in family firms in the United States. In-depth interviews were conducted with eighteen daughters and their parent mentors (nine mothers and nine fathers) using a qualitative case study approach. We identified a reciprocal social exchange process between parent mentors who provided resources and daughters who acquired the knowledge to become successors in their family firms. Significant elements in the preparation process included: positive childhood experiences, choosing and earning a relevant college degree, the daughter’s autonomous decision to enter the family firm, guided on-the-job training, and counsel and advice to overcome the crucial issues of male gender bias and the burden of childcare responsibility. The significance is highlighted of differences that exist between mothers and fathers as mentors regarding understanding the daughters’ position in the firm and communication.

Microcredit offers an innovative response to non-traditional financing and development needs for marginalized individuals. Here, impact assessment is very useful in that it helps to determine whether or not the objectives set at the onset are achieved and what can be done to correct the impediments to achieve better results. The paper analyzes the socio-economic effect of microcredit through the novel dual approach of self-reported perception and relationships with others. The data were gathered in collaboration with the Fonds Mauricie in November, 2019. Apart from the improvement in the financial indicators of micro-enterprises, the results show that microcredit has enhanced micro-entrepreneurs’ living conditions and family situation at rates of 88 and 91 percent, respectively. Regarding morale, 88 percent of micro-entrepreneurs report feeling better and optimistic about the future, and 92 percent report better relationships with others. In particular, the socio-economic effect of microcredit is determined by a better family situation, better living conditions and better financial situation and business income. These results imply that microfinance institutions must extend their financing to all segments of the population, especially the most vulnerable people such as immigrants and indigenous peoples.
