Why Nations Fail
By THOMAS L. FRIEDMAN
March 31, 2012

Co-authored by the M.I.T. economist Daron Acemoglu and the Harvard political scientist James A. Robinson, “Why Nations Fail” argues that the key differentiator between countries is “institutions.” Nations thrive when they develop “inclusive” political and economic institutions, and they fail when those institutions become “extractive” and concentrate power and opportunity in the hands of only a few.
“Inclusive economic institutions that enforce property rights, create a level playing field, and encourage investments in new technologies and skills are more conducive to economic growth than extractive economic institutions that are structured to extract resources from the many by the few,” they write.

“Inclusive economic institutions, are in turn supported by, and support, inclusive political institutions,” which “distribute political power widely in a pluralistic manner and are able to achieve some amount of political centralization so as to establish law and order, the foundations of secure property rights, and an inclusive market economy.” Conversely, extractive political institutions that concentrate power in the hands of a few reinforce extractive economic institutions to hold power.

Acemoglu explained in an interview that their core point is that countries thrive when they build political and economic institutions that “unleash,” empower and protect the full potential of each citizen to innovate, invest and develop.
