Economic sanctions are the big geoeconomic bazooka. But what does history tell us about how well they work, and their relevance today. And does the theory match the data? Moritz Schularick of the Kiel Institute for the World Economy and CEPR talks to Tim Phillips about the evidence of the history of sanctions on what they can achieve, whether we expect too much too soon from small sanctions – and whether politicians are prepared to impose the sanctions that bite.

Biodiversity is essential for the wide range of economic activities that our planet needs. Yet, the economic consequences of its global decline are hard to estimate, because most population studies focus on individual species in isolation. Frederik Noack of the University of British Columbia argues that this misses a central insight about biodiversity: a healthy environment depends not just on individual species, but also on the way they work together to keep our natural environment in balance. One especially important aspect of this is the way that birds help keep crops safe from pests and reduce the need for pesticides. He tells Tim Phillips about the long-term decline of bird populations in the US and the knock-on effect on agriculture, and pollution. 

In 2021, at COP26, the International Accounting Standards Board announced it would create a standard for this reporting. It wants to integrate sustainability reporting with traditional IFRS accounting. Should firms be compelled by regulators to disclose their impact on the climate in their corporate reporting? Investors value convergence in sustainability reporting standards, but they are facing stiff opposition both in the US and Europe – even while developing economies embrace the new regime. Lucrezia Reichlin of the London Business School and CEPR talked to Tim Phillips on the progress to sustainability standards, the scope of reporting, who wants it, and who’s objecting to it. 

In Europe and beyond, populist politicians continue to gain ground. What message are voters sending? Are politicians from other parties listening, and explaining their policies in a way that will successfully reach supporters of populist parties? There are one set of policies for which this may be a huge problem soon. What does this mean for that those tricky choices that politicians will have to make when dealing with the consequences of climate change, and sustainability? Sergei Guriev of London Business School and Catherine de Vries of Bocconi University have both examined what is driving support for populism, and the implications of populism in politics for the social contract. They tell Tim Phillips why the planet may have a populism problem.

Our economy is embedded in nature, but nature is in danger. External funding is needed, especially in the Global South, to support the conservation of our natural ecosystems. Markets can play a role, but the way in which voluntary carbon markets do this has low public trust which, from recent news, may be deserved. Estelle Cantillon of Université libre de Bruxelles and CEPR tells Tim Phillips about her proposal for a new market mechanism to channel funds to projects that will conserve or restore our natural environment by paying dividends to those who invest. But how will it avoid greenwashing, and who will buy the shares?

“What is needed is non-marginal, transformative change to shift the economy, technology, and society”. That’s the typically forthright recommendation from Rick van der Ploeg of the University of Oxford and University of Amsterdam for how to ensure that climate policy is effective at changing our habits and behaviour. He argues that the gradual changes in habits that current policies target don’t go far enough, and that we run the risk of backsliding. But what does this mean in practice? Rick spoke to Tim Phillips about what policies to push, when to push them – and how big the push needs to be.

We are familiar with climate policy to reduce emissions. We know about the policies to adapt to climate change. But can we successfully reduce the amount of CO2 in the atmosphere, and how do we create policies and incentives to invest in, and take advantage of, those technologies? Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research and chair of the European Scientific Advisory Board on Climate Change, talks to Tim Phillips about an aspect of climate policy that is becoming increasingly important. 

"The Economics of Biodiversity” was published by the UK Treasury in 2021. It sets out how economic systems value biodiversity and natural capital, and which policies would preserve and restore nature. The project leader was Professor Sir Partha Dasgupta of the University of Cambridge. In the latest of our special episodes recorded at the first Hoffmann Centre / CEPR / ReCIPE Conference continue, he tells Tim Phillips what he learned from hanging out with ecologists, why we need indicators of economic performance that value nature, and why we should worry about the decline of natural capital.  The Economics of Biodiversity: The Dasgupta Review https://www.gov.uk/government/publications/final-report-the-economics-of-biodiversity-the-dasgupta-review

Can COP 30 get the green transition back on track? It’s not a great time for international cooperation right now and, with hindsight, was the period from 2017 to 2022 a “golden moment” the climate transition, and was it an opportunity missed? That’s the argument presented by Livio Stracca, Deputy Director General Financial Stability at the European Central Bank, also the chair of NGFS work on climate scenarios. He talks to Tim Phillips about what we can learn from this golden moment, and what can be done this time around to avoid the dangers of what Livio calls “climate agenda fatigue” among both the public and governments. 

In the first of our special episodes from the first Hoffmann Centre / CEPR / ReCIPE Conference, we’re discussing what chances there are of significant multilateral agreements being signed at COP 30 and, given that the chances are low, what plan B might be. Beatrice Weder di Mauro of CEPR, Hoffmann Centre and the Geneva Graduate Institute tells Tim Phillips that, if everyone can’t agree, then coalitions of the willing – climate or finance clubs that offer incentives for the countries that want to join – can agree their own sustainability policies. But what are those incentives? And who will lead?

A decade ago, the UK voted in a referendum to leave the European Union. It was the culmination of years of partisan arguments over membership. During that time, most newspapers in the UK took strong “leave” or “remain” positions in the stories they wrote. But were they less obviously partisan in their choice of pictures too? Wanyu Chung of University of Birmingham and CEPR was one of a team of researchers that used artificial intelligence to estimate the emotional impact of news images of politicians before and after the Brexit vote.

The International Macroeconomic History Online Seminar Series, hosted by CEPR, is turning 100 this month — not years, but episodes. What began as a lockdown experiment has become a global fixture for anyone who believes economics never forgets. In a special edition of VoxTalks Economics, Tim Phillips talks with organisers Nathan Sussman and Rui Esteves of the Geneva Graduate Institute about the moments that shaped the series and what a hundred lessons from history can teach us today. Why does history matter so much to economists? And how can the series help us understand current events?  Nathan’s selection The great demographic reversal https://cepr.org/multimedia/imhos-13-great-demographic-reversal-ageing-societies-waning-inequality-and-inflation Monetary and fiscal history of the US https://cepr.org/multimedia/imhos-81-monetary-and-fiscal-history-united-states-1961-2021 The journey of humanity https://cepr.org/multimedia/imhos-37-journey-humanity Rui’s selection The Smoot-Hawley trade war https://cepr.org/multimedia/imhos-26-smoot-hawley-trade-war Financial sanctions https://cepr.org/multimedia/imhos-59-financial-sanctions-arsenal-democracy-or-feeble-weapon Industrial policy https://cepr.org/multimedia/imhos-93-panel-industrial-policy-history

In the second of our episodes based on the topics discussed at the conference “Addressing the Risks and Responses to Climate Overshoot”, organised by the AXA Research Fund, CEPR, and Paris School of Economics, Tim Phillips talks to Matthias Kalkuhl of the University of Potsdam about how to remove carbon from the atmosphere. The innovative technologies that might be able to do this in the future need investment now – so one idea is for firms to buy the right to emit carbon now, as long as they commit to remove carbon when mature technology exists. But to administer this, Europe would need a dedicated Carbon Central Bank. Who would be in charge of it, how would it work, and is any politician brave enough to set it up?

In the first of two podcasts recorded at the conference “Addressing the Risks and Responses to Climate Overshoot”, organised by the AXA Research Fund, CEPR, and Paris School of Economics, Tim Phillips talks to Franck Courchamp of the University of Paris-Saclay about an aspect of climate change that is rarely talked about, increasingly important, and very costly. When plants or animals move, or are moved, to a place they don't belong, there is a risk of damage to natural habitats and an economic cost too. So how do we estimate the size of this risk, and what can we do about it? 

It’s cultural meme that teenagers in New York and Seoul will have more in common with each other than with their parents. Has where we come from been downgraded as an influence on what we like, or is there still what Thierry Mayer of Sciences Po and CEPR calls “gravity in tastes”?  His research focuses on a very important aspect of this question: regional French food. Is there still a France of butter, and a France of olive oil? And, if there is, can we draw it on a map, or is this now a cultural and social divide, rather than a regional one?

We are up to our necks in advice about how to innovate in business, how to succeed as a founder, or how to spot a great startup. Blogs, YouTube channels and airport bookshops claim to reveal the secret. And yet, investors and incubators have a very patchy track record in picking winners.  What if there was a better way to spot entrepreneurs who are more likely to succeed? Konrad Stahl of University of Mannheim is one of a team of researchers who have found one indicator of success that dominates all the others. He tells Tim Phillips what it is, and why it matters.

Today generative AI makes it easy to create and distribute convincing fake news stories, pictures, even videos. We’ve all been hoodwinked – but does that undermine our trust and confidence in the mainstream media? Ruben Durante of National University of Singapore, IPF-ICREA and CEPR is one of the authors of new research that tests how AI-generated misinformation affects our desire for real news. He tells Tim Phillips the good news and bad news for the future of the media’s business model.

The annual meeting of the World Economic Forum, in Davos, attended by thousands of business and policy VIPs – is one of those events that pops up on the news every year, as we see photos of multinational CEOs shaking hands with world leaders and taking part in panel discussions on the future of the planet. But how valuable is it to the business people who pay hundreds of thousands of Swiss Francs to attend? Does Davos create business value, or might it be a high-profile way for them to ski and party – in the words of a new discussion paper published by CEPR, is it any more than “a boondoggle”? Andreas Fuchs of University of Goettingen is one of the researchers who asked this question. He reveals to Tim Phillips the size of the impact on stock prices and credit ratings.

The belief that women are in some way inferior to men has been around for centuries. And throughout that time, women have suffered the consequences. Economists have lately been trying to understand more about the origins of gender biased norms, to help create better policies to challenge them. Their work can build on insights from sociology, anthropology and gender studies, but also raises important questions about the roles of men and women in society. So what should policy attempt to change?  Siwan Anderson of Vancouver School of Economics and CEPR talks to Tim Phillips about what we know on these topics – and the most promising directions for future research.

On 4 August, Paul Atkins, the chair of the US Securities and Exchange Commission, launched “Project Crypto”. The SEC wants to make the US “the crypto capital of the world”. Crypto investors make a lot of noise, but who are they, and do they behave differently to other retail investors? A new CEPR discussion paper called “Do you even crypto, bro?” summarises what a representative sample of US citizens think about crypto investments and highlights the gap in attitudes to risk and investing between crypto holders and the rest of the population. Michael Weber of Purdue University is one of the authors, and he tells Tim Phillips about the beliefs, the politics and the attitude to investment gains that have typified the crypto market so far.
