Microfoundational research increasingly strives to examine the interlinkages between various higher- and lower-level structures. To better capture microfounded change processes, I develop the multi-dimensional concept of institutional entrepreneurs’ skills that defines actors’ abilities to enhance institutional change. By a systematic literature review on institutional entrepreneurship, I identify seven institutional entrepreneurs’ skill dimensions: (i) analytical skills, (ii) empathic skills, (iii) framing skills, (iv) translational skills, (v) organizational skills, (vi) tactical skills, and (vii) timing skills. The established concept provides opportunities for future microfoundational research by examining the formation and the application of the seven skill dimensions.
