A copy of the published paper based on the lecture is available here. The abstract reads,
I argue that it has been hard to make progress on Coase's theory of the firm agenda because of the difficulty of formalizing haggling costs. I propose an approach that tries to move things forward using the idea of aggrievement costs, and apply it to the question of whether a transaction should be placed inside a firm (in-house production) or in the market place (outsourcing).Oliver Hart is the Andrew E Furer Professor of Economics at Harvard University, where he has been teaching since 1993.
