Can private profit ever truly serve the public interest?

Panel Discussion: Public Interest vs Private Profit - Alderman Professor Michael Mainelli · 30:49 · Video: Gresham College · Watch at the source

In short: In the high-stakes world of global finance, the tension between corporate gain and societal good is a constant friction. Alderman Professor Michael Mainelli explores this paradox, drawing on a career that spans rocket science, merchant banking, and the governance of one of the world's most significant trading hubs.

The debate over public interest versus private profit is a cornerstone of modern economic thought, particularly within the City of London. This tension is examined through the lens of the 2015 Sir Thomas Gresham Finance Lecture. The discussion centers on how financial systems—traditionally driven by profit—can be steered toward societal advancement. This is not a new inquiry; Gresham College has been hosting public lectures since 1597 to foster intellectual exchange on such foundational issues.

The perspective offered by Michael Mainelli is shaped by a diverse, multidisciplinary background. A qualified accountant and securities professional, Mainelli holds a PhD in chaotic systems from the London School of Economics. He has held various positions, including aerospace research scientist, global consulting senior partner, and director of the 14,000-person Defence Evaluation & Research Agency under the Ministry of Defence. This blend of 'hard' science, military logistics, and high-finance provides a unique framework for understanding complex systems.

Mainelli’s work with the Z/Yen Group, a think-tank founded in 1994, specifically promotes societal progress through improved finance and technology. By developing indices for Green Finance and Smart Centres, he seeks to quantify and incentivize positive externalities. As the initial US-born Lord Mayor of the City of London (elected 2024), he demonstrates how individual guidance can balance the City's status as a worldwide commerce centre with the needs of local residents and the broader community.

Ultimately, the goal is to move beyond the binary of 'profit vs. public' toward a model of 'better finance.' By applying the study of chaotic systems to economic policy, Mainelli and his peers aim to create stable, innovative structures where private enterprise acts as a vehicle for public prosperity rather than a competitor to it.
