This paper consists of an introductory survey of two fundamental questions regarding the link between entrepreneurship and economic growth. The first one deals with the endogenous relationship between entrepreneurship and growth. In particular, we suggest that, while more entrepreneurship could mean more economic growth, economic growth in turn could affect the individual arbitrage between different professional occupations (including entrepreneurship) and expected payoffs. The second question is concerned with the types of activities to which the individual directs his talents. We distinguish between entrepreneurship and rent-seeking. The impact on economic growth is assessed in static and dynamic frameworks.
