This document discusses ways to expand on William Baumol's typology of productive, unproductive, and destructive entrepreneurship. It suggests social entrepreneurs can teach conventional entrepreneurs by demonstrating that value is created for multiple stakeholders, not just the entrepreneur. A more comprehensive framework is needed to analyze entrepreneurial ventures across economic, social, and process dimensions. This could involve mapping intended and achieved rents or externalities for stakeholders. Analytic tools from fields like set theory, tensor calculus, and cluster analysis may help classify different types of entrepreneurial models and their effectiveness. The goal is to better understand entrepreneurial intentions and impacts to improve measurement and share best practices.
