"If entrepreneurship remains as important to the economy as ever, then the continuing failure of mainstream economics to adequately account for entrepreneurship indicates that fundamental principles require re-evaluation" (John R. Shook, J. of Economic Methodology 10:2 p.181, 2003). Entrepreneurial economics is the study of the entrepreneur and entrepreneurship within the economy. Entrepreneurship plays an critical role in the 'real life' economy yet mainstream economic theory neglets entrepreneurship. Economists are in fact question whether it fits into the theory. There are many possible explanations for the neglect of entrepreneurship by mainstream economic theory. Some scholars attribute this to the fact that entrepreneurship has been perceived as a chaotic, unpredictable economic process, which cannot be modeled using the analytical methods used in mainstream economic theory. Others to the approaches that tend to treat entrepreneurship as autonomous from ongoing economic systems. It seems no longer possible to expect that only theoretical refinements and extending known principles can provide for a theory of entrepreneurship. Challenging 'fundamental principles' like equilibrium models, rational agent, maximization paradigm, the traditional production function, and applying insight from other disciplines like theoretical physics (thermodynamics, fluid dynamics, statistical statistics, entropy) might be the way forward in the study of entrepreneurial economics. Coase surveys the field of economics and believes it has become a "theory-driven" subject that has moved into a paradigm in which conclusions take precedence over problems. "If you look at a page of a scientific journal like Nature," he said, "every few weeks you have statements such as, 'We’ll have to think it out again. These results aren’t going the way we thought they would.' Well, in economics, the results always go the way we thought they would because we approach the problems in the same way, only asking certain questions." This blog is about developing Entrepreneurial Economics by challenging fundamental principles, using new insights from models and theories in the natural sciences (mainly theoretical physics) and citing Coase "We’ll have to think it out again. These results aren’t going the way we thought they would." We are now editing a book "The Emergence of Entrepreneurial Econonomics" for Elsevier. Interesting contributions are welcome.
