“…We operationalize this variable with the county-level measure of regional social capital developed by Rupasingha et al (2006, with updates), also known as the Penn State Data. While not perfect, this measure is one of the most promising extant indicators of regional social capital, captures elements of both bridging and bonding social capital (Vâlsan et al, 2023) and is widely used across a variety of disciplines (e.g., Hasan et al, 2017; Holtkamp & Weaver, 2018; Hwang & Lee, 2023; Jensen & Ramey, 2020), including entrepreneurship (e.g., Conroy & Deller, 2020; Cordero, 2023; Vedula & Kim, 2019). 3 The Penn State measure is based on the density (per 1,000 inhabitants) of “horizontally ordered groups (like sports clubs, co-operatives, mutual aid societies, cultural associations, and voluntary unions)” (Putnam et al, 1993: 175) in a county in a year.…”
