"Good Economics for Hard Times" by Abhijit Banerjee and Esther Duflo is a comprehensive guide to modern economic theory. The book discusses various topics, including democracy, migration, comparative advantages, and the impact of community on individuals. #bookreview #BookTwitter The book starts with a quote from a mathematician/physicist who challenges Paul Samuelson to "name me one proposition in all of the social sciences which is both true and non-trivial."

“The knowledge needed to provide citizens of the poorest countries with vastly improved standards of living already exists in the advanced countries”— What we need to do is to guarantee private property and provide incentive. Nigeria is in a very peculiar position to adopt and use most of the available knowledge.

Our size and demography provides a relatively strong incentive. What we have struggled with is the guarantee of private property.
