Exploration and Exploitation - The Role of Entrepreneurship and R+D in the Process of Innovation
We formulate a model that explicitly separates two functions in the innovation process: The introduction of new goods and the quality improvement of existing goods. While the latter is performed by the corporate R+D sector, the first is performed by entrepreneurs. We show that in a three sector economy, which also includes a producing sector, there exists a stable non trivial allocation of labor to production, innovation and entrepreneurship. We compute the steady state allocation of labor to production, R+D and Entrepreneurship. We show that the innovation rate decreases if one of the innovative sectors does not exist.
