Mark Sanders, Max Planck Institute for Research on Economic Systems Seminar at Max Planck Institute Tuesday, March 21st , 2005 slide 7 of 15 Scientific (R)evolution A Model of Scientific Activity where function f(.) is the knowledge filter and nP-n is the universe of opportunities. New products is then proportional to the number of unexploited opportunities and depends on the level of entrepreneurial R&D. This activity is profit driven.
Mark Sanders, Max Planck Institute for Research on Economic Systems Seminar at Max Planck Institute Tuesday, March 21st , 2005 slide 8 of 15 Scientific (R)evolution A Model of Scientific Activity where function g(.) captures the role of entrepreneurial vision and talent. Opportunities are recognized and combine a number of scientific ideas. It is therefore positive in the stock of scientific ideas.
