On 7th September 2026, UCL Centre for Finance will have the honour of welcoming Jean Tirole, Nobel Prize-winning economist, for a prestigious seminar. Tirole, renowned for his groundbreaking work in industrial organization and market regulation, will share his insights on contemporary economic challenges.

His presentation will focus on his recent paper entitled "Engineering Commonality," which explores how trust can be engineered within teams and organizations to promote cooperation and increase collective effort.

Abstract: Mutual trust, whether it results from shared goals, empathy, a long-lasting relationship, or common priors, is the lubricant that makes organizations and society operable. Besides designing team incentives when feasible, the latter accordingly stress what unites their members and abhor what divides. They regulate acceptable discourse, facilitate team building, spread commonality narratives, and rewrite history. The paper builds a framework in which members of a team are more likely to exert effort if their teammates do (strategic complementarity) and they can trust each other (congruence). They predict congruence on the task based on experiments, for example by exchanging on a variety of otherwise task-irrelevant traits. The paper obtains the optimal communication protocols for the agents and for the organization and asks whether these protocols are robust to misrepresentations and to additional exchange of information. It also studies the organization’s communication about membership and values.
