Book excerpt: This book presents scholarly reflections on women's entrepreneurial propensity and on women's entrepreneurship in Science, Technology, Engineering, and Mathematics (STEM) fields. Contributing to a country's innovativeness and competitiveness, women entrepreneurs also promote healthy social and economic growth and act as mentors and role models for younger women. However, the low involvement of women in STEM, which begins at education, affects the share of women entrepreneurs in these fields. The authors address these issues and highlight the output of research studies by bringing together both global and country-specific evidence. Researchers and policymakers interested in advancing women's entrepreneurship, especially in STEM, will particularly benefit from this book.
