This note introduces an evolutionary approach to economic and governance reform. It lays out two especially prevalent trajectories that differ starkly from one another in how they prioritize and sequence economic growth, state building, and the development of civil society and political...

Utopian socialists believed that socialism is inevitable because it is a more rational system to organize production and life, a system more in line with the “good” nature of human beings. Marxism rejected this reasoning replacing it with what is known as historical materialism: social...

Does democracy promote economic development? This paper reviews recent attempts to address this question that exploited within-country variation. It shows that the answer is largely positive, but also depends on the details of democratic reforms. First, the sequence of economic vs political...

I introduce patents into a general equilibrium model of innovation, where innovators choose between creating a new product market and competing in an existing market. Patent holders demand royalties from sequential innovators, but are constrained by the ability of innovators to work around...
