His research interests are around political decision-making, the role of civil servants in that and how that then passes through to institutional memory.



Mohamed Saleh is a Professor of Economics at the Toulouse School of Economics, and a member of the IAST. His research interests are in economic history, and the economic history of the Middle East and North Africa in particular. 


Catherine Haddon is the resident historian at the Institute for Government. Catherine also leads the Institute's work on changes of government, ministers and the workings of the constitution, and heads the Institute's professional development programme of ministers and opposition parties.

Why has it become so hard to run government?

Why have economists ignored nature for so long - and now they have discovered it, are they measuring it correctly?

This episode tackles the issue of incorporating nature into economic measurements. These include whether there is still a trade-off between economic growth and the environment, what is still missing from economic measures, and how to get academics and policymakers to work together. 

This episode is hosted by Rory Cellan-Jones, and features expert guests Dr Matthew Agarwala and Dr Cristina Peñasco from the Bennett Institute for Public Policy, and Nicolas Treich, from the Institute for Advanced Study in Toulouse.

Dr Matthew Agawala is an economist at the Bennett Institute, and project lead for their Wealth Economy project.

Dr Cristina Peñasco is a University Lecturer in Public Policy at POLIS, a Centre Fellow at Centre for the Environment, Energy and Natural Resource Governance (C-EENRG) hosted at the Department of Land Economy, and an associate researcher of the Bennett Institute for Public Policy. Her research brings together work in environmental economics, innovation policy and energy economics in green and energy efficiency technologies, with a focus on the policy instruments enabling the transition to low-carbon economy.

Nicolas Treich is a research associate at Toulouse School of Economics and INRAE (French National Research Institute for Agriculture, Food and the Environment). His work focuses on decision theory, environmental economics, and, more recently, on animal welfare.

What is nature's role in the economy?

Hope versus fear in artificial intelligence

In this third episode of Crossing Channels, experts from the Bennett Institute for Public Policy, Cambridge, and the Institute for Advanced Study in Toulouse (IAST), discuss the ethics of artificial intelligence (AI), including why we need to care about it, who is responsible for it, and whether there’s a double standard for AI and humans.

Host Rory Cellan-Jones talks to Dr Jean-Francois Bonnefon and Professor Daniel Chen from IAST, and Professor Diane Coyle from the Bennett Institute.

Ukraine invasion: context, consequences and the information war

Guests Catherine Barnard and Emmanuelle Auriol discuss how migration affects labour markets, legal protections and social cohesion, how economic incentives and border regimes shape who migrates and why, and what smarter, fairer migration policies could look like in the years ahead.

In this final episode of season 4, Richard Westcott is joined by Catherine Barnard (University of Cambridge) and Emmanuelle Auriol (Toulouse School of Economics) to unpack the economic, legal, and social dimensions of migration.

Drawing on insights from law and economics, the conversation explores how migration affects labour markets, legal protections, and social cohesion, from post-Brexit realities in Great Yarmouth to global questions of fairness and opportunity. The episode examines who moves and why, the limits of current border regimes, and what more effective and ethical migration policies could look like.
