Bengt Holmstrom

Bengt Holmstrom, a Finnish-American economist at MIT, shared the 2016 Nobel Memorial Prize in Economics with Oliver Hart. He was recognized for his foundational contributions to contract theory, particularly regarding how contracts align the incentives of parties with hidden actions. His models are widely used to analyze executive compensation, insurance, and employment.

The informativeness principle, developed by Bengt Holmstrom, states that an agent's contract should be based on any observable signal that provides information about their effort. By tying compensation to factors that correlate with the agent's hidden actions, it reduces moral hazard. This principle is heavily applied in modern corporate governance to design CEO bonus structures.

Bengt Holmstrom is a long-time faculty member at the Massachusetts Institute of Technology (MIT), serving as a professor of economics. His move to MIT in the 1980s coincided with his most influential work on principal-agent models and contract theory. He remains a highly cited and active figure in the field of microeconomic theory.

Holmstrom developed models to address the "free-rider" problem that occurs when workers' individual contributions cannot be easily measured in a team setting. He showed that to induce optimal effort, a firm might need to enforce budget-breaking penalties or utilize external monitors. This provided a mathematical rationale for why independent owners and supervisors are necessary in collective work environments.
