This book presents an innovative analysis of the solidarity/social economy among low-income religious women in Iran. For years, the role of low-income women in community care and poverty reduction has been underestimated and under-researched in the broader academic community, due to the...

Do political connections affect firm dynamics, innovation, and creative destruction? We study Italian firms and their workers to answer this question. Our analysis uses a brand-new dataset, spanning the period from 1993 to 2014, where we merge: (i) firm-level balance sheet data; (ii) social...
