Oliver Hart

Oliver Hart, a British-American Harvard economist, shared the 2016 Nobel Memorial Prize in Economics with Bengt Holmstrom. He was awarded the prize for his foundational contributions to contract theory, specifically his work on incomplete contracts. His research helps explain how contracts are designed to handle situations where all future events cannot be predicted.

Hart's theory of incomplete contracts argues that because it is impossible to foresee every future contingency, contracts must necessarily leave some decisions unresolved. He demonstrated that the allocation of control rights, or who owns the physical assets, becomes crucial in these scenarios. This framework is widely used to understand corporate governance and the boundaries of the firm.

Oliver Hart is a prominent professor at Harvard University, where he has spent a significant portion of his academic career. As a British-American economist, his research at Harvard has heavily influenced modern microeconomic theory and law and economics. He continues to be a leading voice in the field of contract theory.

By focusing on asset ownership and residual control rights, Oliver Hart provided a new way to understand why firms merge or outsource activities. He showed that a firm should integrate internally if the relationship-specific investments require one party to strictly own the residual control rights. This shifted the focus of vertical integration theory toward the allocation of power rather than just transaction costs.
