On 17 August 2023 we hosted a transdisciplinary roundtable, facilitating a conversation about “Resilient Democracies: On the role of trust, participation and combatting disinformation” featuring speakers with expertise in economics, mathematics, political theory, and international politics. You can find a recording of the session here. For photos taken on the day, follow this link.

One of the guest speakers, Professor Massimo Morelli also contributed a public lecture on “The Shift to Commitment Politics and Populism” later that day (see related CEPR Discussion Paper for more on this, or alternatively, read this working paper version) — access the recording of this public lecture on YouTube here — , and gave an interview in the media on related topics to those discussed in the roundtable and the public lecture, which you can read more about here.

Title of the talk: The Shift to Commitment Politics and Populism” [working paper version –  slides & recording of the public lecture]

Date, Time and Venue: Thursday, 17 August 2023, 5.15pm – 6pm, Registration, drinks & canapés, Level 1 Foyer, Sir OGGB, 6pm – 7.30pm, Lecture and Audience Q&A, Sir OGGB, Room OGGB 5, Level 0

Abstract: The decline in voters’ trust in government and the rise of populism are two concerning features of contemporary politics in Europe and United States. In the lecture I plan to introduce a model of commitment politics that elucidates the interplay between distrust and populism. Candidates supply policy commitments to mitigate voters’ distrust in government, shrinking politicians’ levels of discretion typical of representative democracies. Alongside commitments, candidates rationally choose the main strategies associated with populism, namely anti-elite and pro-people rhetoric. With novel data on voters’ distrust towards the U.S. federal government, which we match with the Twitter activity of more than 2,000 candidates over five congressional elections, we show that distrust is strongly associated with candidates’ supply of commitments and populist rhetoric, which are also effective strategies at mobilizing distrustful voters. I also plan to show that the shift to commitment politics determines greater aversion to checks and balances, and hence even illiberal populism can emerge. Free media, judiciary independence, and professional bureaucrats, are all “agencies of restraint’’ of an executive, and hence the voters who prefer the policy commitments of their chosen candidate to executive power prefer the reduction of strength of all such agencies.

Bio: Massimo Morelli has been elected Fellow of the Econometric Society – and Society for the Advancement of Economic Theory – mostly for his contributions to bargaining, political economy and economics of conflict, while his current work also deals with causes and consequences of populism and law and economics in general. He obtained a PhD in economics from Harvard in 1996 and went back to Italy (Bocconi) in 2014, after having taught at multiple universities in the US, including Columbia University. He has been an active member of the Council of the European Economic Association and is now chairing the Minorities in Economics (MinE) committee, with a growing passion for all diversity and inclusion concerns.

Revamp of CMSS

Our centre has been formally reviewed in December 2013, and we have decided to try to grow.

(coming soon)

There will be a new Advisory Board, which is smaller and not solely composed of academic researchers. Expect to see minor changes to this website soon.

(Apologies for this attempt at a joke – with several staff on leave, nothing much has happened so far this semester, but we expect some interesting news before the end of the year).
