Research indicates that societal norms, industry practices, and government policy within many Western societies are creating a precariat ageing women population who are welfare-dependent, experiencing challenges in finding meaningful jobs and living in poverty with low self-efficacy. Appropriate entrepreneurial intervention programs are seen as critical labour market solutions which can help people out of precarious situations and into self-employment. Within the Global South, an increasing number of ageing women are turning to entrepreneurship out of necessity due to societal failures that have excluded them from the job market. However, many are not as successful; this study argues that entrepreneurial intervention programs supported by formal institutions are crucial for helping ageing women escape precarious situations. Using an action research case study from Australia involving precarious women, we showcase the importance of institutional support in ehnancing this group’s self-efficacy and influencing the creation, development, and sustainability of businesses. By employing a holistic approach, we analyse the factors that shape the entrepreneurial environment—from government regulation to social norms—to provide a comprehensive understanding of the interaction between institutions and entrepreneurship.
