Harvard economist Dani Rodrik gave a really interesting talk today at the Ostrom Workshop on the need to bring ideas back into rational choice-based theories of political-economy, which for a long time has been almost completely dominated by interest-based theories, such as public choice. Without denying the important role interests play, Rodrik offered a refreshing analysis of the important roles ideas and imagination serve in reducing political constraints to economic growth.
Unfortunately, Rodrik's presentation was not accompanied by a working paper. No doubt a paper will emerge eventually. When it does, I'll link to it.
