We investigate whether the impact of institutions depends not just on their current state but also on how they came to be. In particular, we hypothesize that while economic freedom that emerges spontaneously may be growth promoting, economic freedom that emerges as a result of costly lobbying efforts may be less fruitful.

The aim of this paper is to explore how interpersonal variation in risk preference affects human capital investment and wage growth.

We investigate the link between risk preference, human capital investm...
