"Due to its formality and highly analytic thinking, economics is often attributed a leading role among the social sciences and a prominent position as contributor to economic or social issues in the real world. Fact is, however, that the empirical proof for such a claim is either missing or anecdotal. This paper aims to outline the ""economics of economics”. It surveys and compares approaches of impact measurement such as a production function of economics or the demand and supply of trained economists. It furthermore discriminates between the impact of economicnideas versus that of economists as scientists or politicians."
