Professor Caroline Elliott has taken up a prestigious role on the UK’s Regulatory Policy Committee (RPC), an independent body of experts which assesses the quality of evidence and analysis used to inform government regulatory proposals.

Since taking up her appointment in March she has already provided expert review on a range of policy issues including multiple drafts of a white paper, an impact assessment for proposed secondary legislation, and two post-implementation reviews.

Looking towards the future, Caroline said: “I hope that I’ll be able to make a difference by using my applied research knowledge and my academic skills on the impact assessments. We’re also going to start looking at policy options assessments and I’m excited to bring my knowledge to bear on the independent reviews.”

Caroline is continuing a tradition of Warwick economists contributing to the work of the committee – the position became vacant when Dr Jonathan Cave’s term of appointment came to an end. He is delighted that, after a rigorous selection process, the Committee chose to appoint another “proper card-carrying academic economist.”

Caroline said: “Jonathan sent me the advertisement for the role, and when I looked into the work of the committee, I thought it looked amazing. I teach industrial economics, regulation and competition policy and I always try and link my teaching to the real world - I never want to be criticised as being an ivory tower academic. Here was an opportunity to put my work into practice – to not just comment on the work of others, or the work of the government, but to be directly involved.

“As an economist, and as an academic economist, I believe there are two things I bring to the role. The first is my familiarity with academic literature and evidence. The second way in which I feel I’m contributing comes back to my academic training. As an academic, as an applied economist, you’re always looking for data. Sometimes you’re having to pull data together from different sources. And because I come from this background I can assist with this.”

Jonathan is delighted that Caroline has been appointed as his successor. “I think because I kept citing peer-reviewed literature in my Opinions and other interventions, trying to ensure that regulatory analysis made appropriate use of economic empirical methodologies and theoretical tools, including the use of real options analysis - I think they saw the value of having a replacement who is similarly positioned.”

Asked if he had any advice for Caroline, Jonathan said: “Don’t be afraid to challenge people and to be the voice within the committee resisting calls to compromise when that isn’t appropriate, by ensuring that the impacts of whatever regulations ministers wish to propose are rigorously assessed against real problems, but without being drawn into comments about whether the policies themselves are ‘right’ or ‘wrong’.

“I’d encourage her to be very actively engaged with the new government in a partnership based on a culture of evaluation and analysis and a mechanism design view of regulations and the regulatory process of which the RPC is a part. She should strive to remain committed to the concept and values of better regulation and work hard to make those concepts her own – in the committee, in her academic research and teaching and in leaving her mark on the better regulation framework itself.

“If you see how policies are made you can build better regulatory economics models. Regulation is not a matter of feeding a problem into a machine, turning a crank on a machine and ‘solving’ the problem – politics intervenes, economics intervenes, delays intervene, and the things you should be looking for are not always where they should be. For instance, we spent a lot of time worrying about how – or whether – to scrutinise the impacts when government threatens to regulate, business behaviour changes in anticipation and the regulation is abandoned. I think Caroline will find this useful in her academic work, and her teaching.”

Jonathan says that his decade as an RPC member was “fascinating” and saw many changes and developments. He worked hard to encourage the committee to avoid compromising or watering down its opinions for spurious reasons, arguing against “voices that felt we should temporise or give green ratings to things that did not merit them, for the fear that the political cost of refusing would be too high.” Rather than asking if each contested Bill was ‘the right hill to die on’, he tried to sit down with departments to negotiate where possible, and to publish Red opinions where important analytic principles or impacts were not properly acknowledged.

He also became adept at navigating changing political priorities: “I think the biggest lesson I had to learn along the way was how to sail in the direction of better regulation by tacking across a wind blowing from the deregulatory quarter.”

Jonathan also argued strongly for the committee to be allowed to give its opinions at an earlier stage in the policy process: “A few years ago, we only got to look at things when the bills were laid before Parliament, by which time all the decisions had been made. We commented, many times, on impact assessments that were more ex-post rationalisation than a formative influence on the creation of policy – which led to the most tendentious type of data-mining and the temptation to rely on ‘policy-driven evidence.’ Now the RPC is looking at things much earlier in the process, at the options assessment stage.”

In Jonathan’s experience, this particular challenge is not unique to the UK. He said: “I’m very pleased and proud about our international engagement with RegWatch Europe (a network of similar EU scrutiny bodies) our OECD counterpart and OIRA in the United States. I’ve worked closely with them over the years to share best practice and identify common problems, and there has been lot of progress made on this challenge of ex-ante assessment.

“Another challenge is the need to look back and evaluate regulations to see if they have done what they set out to do. I’ve had a long struggle to champion “post-implementation review” and I think we’ve made good progress. The UK is regarded as setting the world standard in this and we’ve been trying to maintain that. That’s been a really good thing.”

Last week, a group of students and staff from the Department of Economics participated in a sensory awareness workshop to gain insights into what it feels like to have a disability.

Dr Juliana Carneiro, the Department’s Disability Coordinator and organiser of the workshop, gave an introduction about the importance of awareness of sensory perception and neurodiversity in our learning and working communities. She said:

“Being aware of how disabled people experience the world gives us a valuable insight into issues related to diversity within our society; it teaches us empathy, encourages inclusivity and helps us build a supportive environment for all members of our community. It is also a soft skill recognised and highly valued by employers in the job market.”

Several speakers were invited to contribute to the topic or tell their story of sensory perception, including:

• Dr Damien Homer, Head of Disability Services who talked about different types of assistance available to Warwick’s students.
• Diana Shore, Assistant Professor, WMG - shared her own experience as a person with a disability which is not always visible to those around her. Diana invited the audience to participate in a role play: Juliana interviewed Diana while fidgeting and making noises, to show the audience the challenges a person with hearing impairment must overcome.
• Nivaria Morales Salas, IT Developer in the Department of Economics, explained in her talk about different categories of visual impairment and shared her own experience as a person with disability.
• Martyn Parker, Community Engagement Officer for Warwickshire Vision came with his guide dog Harper who stole the limelight! Martyn shared his experience of visual impairment and interacted with students walking them through obstacles while they were wearing an eye band.

The participants engaged with a number of other hands-on activities to have a taste of the diversity of sensory perception experienced by people within our community, including the use of a wheelchair.

Nivaria Morales Salas commented about the event:

“It’s great to see events like this being organised on campus. They raise awareness of the reality of living with a disability as well as showing that disabled people make a positive contribution to society despite facing daily challenges.”

More than 20 students and 6 members of staff benefitted from attending the event, fully engaging in the activities and role play and raising their knowledge and understanding of studying, working, and living with diverse people.

Dr Carneiro wishes to thank her colleagues who supported her in organising the event: Claire Johnson, Student Engagement and Experience Coordinator and Tina MacSkimming, Student Support and Progression Officer from the Department of Economics.

Dr Carneiro is also grateful to the sponsors of the event - Professor Rebecca Freeman, Director of the Dean of Student Office, and Professor Lorenzo Frigerio, Pro-Vice Chancellor (Education) - for their support of the Department's Inclusive Education Action Plan.

Two members of the Department are taking on leadership roles in the University’s Research Spotlight programme, a new programme designed to promote collaborative work on urgent global challenges.

Professor Daniel Sgroi has been appointed Chair of the new interdisciplinary Behaviour Spotlight, and Professor Thijs van Rens is a member of the leadership team for the Health Spotlight.

A total of six interdisciplinary ‘Research Spotlights’ have been created. Each of them identifies a major global challenge: “They are all serious interdisciplinary areas that are going to make a big difference,” Daniel explains. “The University has asked, ‘what are the big issues facing the world?’ and decided to put a spotlight on each of them and bring people from every department together to work on them.

“This is important because most of the world’s big problems are problems that can only really be solved by disciplines working together – for example, how we deal with climate change, how we tackle political polarisation, how we handle pandemics.

“We know from COVID that medics worked with behavioural scientists so that they didn’t just develop vaccines, they developed strategies to ensure people would take them.

“Our Behaviour Spotlight aims to facilitate interdisciplinary collaboration between behavioural researchers that seek to understand and address some of the biggest problems faced by the world today.

“We can provide seed funding for pilot experiments or to kick-start projects, we can create and financially support new seminar series, workshops and conferences, and help fund early-stage research.

“We have a big network already, inherited from the Behaviour, Brain & Society GRP, but we now want to reach across the whole university. We’ll be inviting anyone doing behavioural research at Warwick to join us as part of our mission to build a university-wide network of active researchers.”

A new Health Spotlight has also been created. Professor Thijs van Rens is one of four academics on the leadership team. He said:

"There are many people at University working on research that is relevant to health, at Warwick Medical School, of course, but also in Business, Chemistry, Economics, Engineering, English, History, Mathematics, Physics, Psychology, Statistics and probably other departments as well.

“Our aim is to build the network and infrastructure to bring these people together so that together we can make better progress on the big questions that cannot be addressed from a single discipline.

“Some of the interdisciplinary areas that we will focus on are technologies in health, prevention and public health, mental health and wellbeing, and interdisciplinary methodologies. Warwick has strengths in all of these areas, and we hope that by providing a supportive environment for collaboration, we can further build on these strengths and encourage ‘blue-skies’ research ideas.”

“My own research on healthy and sustainable diets has made me realise how the quality of the research can benefit from an interdisciplinary team, and how much it helps to secure funding for that research."

Professor Ben Lockwood, Head of the Economics Department, said “I am delighted that Daniel and Thijs have been appointed to these leadership roles and will be contributing to the University’s ambitious interdisciplinary research programme.”

The Spotlight programme is intended to run for at least 10 years and is an indication of the University’s long-term commitment to world-changing research.

A new research project launched today by a partnership including the University of Warwick will explore how shoppers can be encouraged to make more sustainable food choices while they do their online shopping.

The online shopping project is part of the SALIENT food trials, a consortium of eight universities and two research institutes looking at ways to support healthier eating and reduce the impact of food on the planet, funded by the UK government through the ESRC.

The trial is facilitated by a web browser extension for the online grocery platform of a major UK supermarket, which will pull information from a database of over 14,000 ‘life cycle assessments’ for the available products compiled by food sustainability experts Sustained.

Up to 2750 UK shoppers will be recruited to take part in up to five waves. They will be invited to download a plug-in for their internet browser which will provide two sorts of nudges to help guide their purchases:-

• Eco-labelling: these will inform online shoppers about the environmental footprint of their food choices, using an A (least impact) to G (most impact) rating system.
• Product Swaps: shoppers may be shown products with a lower environmental impact and equal or better nutritional profile, in place of their initial choices. These may also be made available at a discount to test the effect of lower prices on purchase decisions.

The researchers will evaluate the impact of these interventions on the environmental rating of consumers’ shopping baskets, to understand whether either intervention results in more sustainable shopping habits and by how much.

Professor Thijs van Rens, co-lead of the Sustained trial, said: “Offering swaps and price discounts are promising ways to get people to buy more sustainable foods, which are often better for their health too. But we have very little evidence for how effective these interventions are, particularly for online grocery shopping.

“Previous research has mostly focused on physical supermarkets or on simulated online supermarkets. But we know that people often make quite different choices in real life than in simulated environments.

“Our collaboration with Sustained will provide a great opportunity to generate real life data which we can analyse in order to recommend policies with the best chance of changing behaviour in a positive way.”

Professor Oyinlola Oyebode, also co-lead of the research trial, said: “Climate change and environmental degradation are important and serious challenges for human health. Changing the food we produce, buy and eat can help to address this, and more sustainable food often offers direct benefits for health too.”

Carl Oliver, Sustained CEO, said: “Empowering more sustainable purchasing choices is part of the journey to reducing the massive impact the global food system has on the environment.

“This trial is also about understanding how industry and policy makers can utilise technology partners like Sustained to shape a food system that supports the health of us and our planet.

“This is an exciting partnership for Sustained as we work towards our vision of helping consumers and businesses reduce their environmental impact through actionable intelligence and collaboration.”

About SALIENT: SALIENT is a team of researchers working with the public, partners from local and national government, food charities, community support teams, and the food industry, with the goal of designing interventions to support healthier eating and reduce the impact of food on the planet. The SALIENT consortium is drawn from eight universities (Oxford, Cambridge, Warwick, Birmingham, Hertfordshire, Liverpool, London School of Hygiene and Tropical Medicine, and Queen Mary University of London) and two research institutes (Nesta and the Behavioural Insights Team). https://www.salientfoodtrials.uk/

Delegating tax-and-spend powers to local government risks limiting the ability of local authorities to respond to environmental disasters, according to new research published in the Journal of Economic Behavior and Organization.

Dr Jose Rowell Corpuz (University of Warwick), Professor Joseph Capuno (University of the Philippines Diliman) and Dr Samuel Lordemus (University of Lucerne) looked at 10 years of public finance data from the Philippines both before and after a national emergency in 2013, when Typhoon Haiyan struck the islands with 200mph winds, to explore how local public finances respond to natural disasters.

The researchers also looked for evidence of how central government disaster relief funds and international aid affected local revenue raising and spending on essential services – did the external aid compensate for lower local revenues, or was it genuinely additional to existing resources?

While these questions have been studied in better-off countries, it is believed that this study substantially adds to the analysis of the local fiscal response to natural disasters in a country with more limited financial resources.

The Philippines is in a high-risk typhoon area, and Typhoon Haiyan was one of the strongest ever recorded and caused unprecedented damage as it crossed the country. Official government sources estimate that about 6,300 people died, more than 28,000 were injured and 4 million left homeless.

It displaced communities and affected the regions' infrastructure, roads, hospitals, schools, and public services. The severity of the impact on the areas it ravaged was unanticipated and unprecedented, with its effects felt during and after the disaster.

Using data on local government revenue and spending from before and after Typhoon Haiyan, Dr Corpuz and his co-authors found:

• The typhoon had a small impact on local government revenue raising. In the short term there was a fall in income from taxes and charges on local businesses but these recovered after around two years. This effect was more severe in less-well-off municipalities and highlights the importance of flexible central government support to address economic inequality.
• The typhoon had a small but measurable impact on spending. Local governments spent slightly less on all areas of responsibility except health, housing and labour. They also reduced their debt repayments.
• Local governments which received external aid did not diminish their tax collection efforts and spent more on public services, education, social and economic services, and debt repayments. This result shows that foreign aid has a vital role to play in supporting local government to help citizens in the aftermath of disasters.

Commenting on his research Dr Corpuz said:

“The effects of natural disasters can have a huge impact on a local economy and under decentralisation, local governments are limited in the resources they can mobilise in the aftermath.

“Ordinarily, local tax revenue collection provides a higher rate of local government spending over and above central government transfers. This changes after a natural disaster when there are significant losses in revenues particularly from local businesses and economic enterprise.

“When a typhoon as powerful as Haiyan affects the generating revenue capacity of local governments, central government transfers and foreign aid are crucial to maintaining public expenditures that benefit its people.”

Specifically, the research evidence suggests:

• Local governments exposed to common nationwide shocks such as Typhoon Haiyan have limited capacity to reallocate or provide additional resources that would address the increased demand for local public spending.
• Lack of strong and responsive financial support from central government leaves local governments to fend for themselves. This situation only escalates the impact of external shocks.
• Central government needs to step in with additional sources of funding for disaster relief and ensure a coordinated effort with other funding sources (such as foreign aid) to effectively target the most vulnerable communities.

Dr Corpuz concludes:

“Although we cannot generalize, the Philippine case is a reminder of natural disasters’ debilitating effect on local governments and vulnerable communities. We hope that our study will inspire many in ensuring a well-coordinated disaster risk management by central and local governments, particularly in settings of decentralised local government finance.”

August Küenburg (BSc Economics, Year 2) has released an exciting new podcast Econ Bites, exploring economic public policymaking and its key figures and institutions. In his impressive first episode, August interviews Jonathan Haskel, member of the Monetary Policy Committee of the Bank of England, to discuss central bank independence and inflation targeting. We caught up with August about his fascinating new project.

Hi August! Why did you decide to start creating and publishing your own podcast?

Having my own podcast gives me the opportunity to talk to inspiring people in the field of economics about all kinds of interesting topics and share these conversations with other interested people. Preparing a podcast episode is a fun learning experience and an excellent way to deepen my own understanding about certain topics that we begin to cover as undergraduate economics students.

Your first episode has a very exciting guest – Jonathan Haskel. Can you explain who he is and why you’ve chosen to interview him?

Jonathan Haskel is a Professor of Economics at Imperial College Business School and is currently serving his second term as a member of the Monetary Policy Committee (MPC) at the Bank of England. Jonathan holds one of the nine votes to decide the future of the UK monetary policy. His experience as a central banker and ability to explain complex matters with often simple analogies makes him the perfect guest for my podcast episode.

Why should people listen to this episode with Jonathan?

Listeners will hopefully gain a better understanding of how the MPC operates and why inflation targeting and central bank independence are essential to ensure effective and credible monetary policy. Jonathan makes an excellent point about how economists have too long held a machine-like view of the economy and that a major intellectual breakthrough was needed to start treating the economy much more systematically.

For this episode you’ve done a lot of research into the history of the Bank of England and its policymaking on matters such as inflation. How has your degree in economics equipped you with the skills to complete this research?

One of my optional models, Money and Banking, discusses monetary policy and central bank independence in more detail and this motivated me to do further research into central banks. Most of my preparation goes into reading the literature and gaining a solid understanding of the topic.

Your podcast demonstrates a keen interest in policymaking – are you planning to pursue a career path in this area?

At the moment I want to pursue a career in public policy, being as a central banker or maybe as an economist at the International Monetary Fund or World Bank.

Talking to people in those fields is an exciting opportunity for me to learn more about their jobs and why they matter so much. Policymaking has a real impact on people’s lives, and I believe that coming up with new insights and solutions to various economic issues could be a very interesting and fulfilling career prospect.

I hope to have more central bankers, academics and economists working on public policy on my podcast in the future.

Professor Giovanni Ricco has received a prestigious American Economic Journal Best Paper 2024 AwardLink opens in a new window for a paper published in the American Economic Journal: Macroeconomics.

The awards are made annually to the best paper published in each of the four American Economic Journals – Applied Economics, Macroeconomics, Economic Policy and Microeconomics - in the previous three years.  The winning papers are chosen by the journals’ Boards of Editors from those nominated by AEA members.

Professor Ricco’s paper was published in 2021 and is co-authored with Professor Silvia Miranda-Agrippino, Research Economist at the Federal Reserve Bank of New York

In The Transmission of Monetary Policy Shocks Silvia Miranda-Agrippino and Giovanni Ricco study widely used instruments for the identification of monetary policy disturbances, show how the use of these instruments is behind the empirical puzzles reported in the literature, and propose a new high-frequency instrument for monetary policy shocks that accounts for informational rigidities.

Commenting on his award, Professor Ricco said it was a complete surprise but a very welcome one.

Head of Department Ben Lockwood said: “On behalf of all in Warwick Economics I’d like to congratulate Giovanni on his ‘best paper’ award. It is a significant achievement for him personally and an important accolade for the Department."

Historical experience of battles fought with physically-demanding weapons created a preference for sons over daughters which persists to the present day, according to new research.

India’s population is disproportionately male compared to global norms. A preference for sons over daughters has resulted in some 63 million women “missing” from the population. While Amartya Sen drew attention to these “missing women” in the early 1990s, this deficit was recognized as early as the 1881 census.

While mechanisms such as sex-selective abortion and prioritising male children over female children can explain the imbalance, what is it that creates the preference for male children in the first place?

In a new Warwick Economics Research Papers (WERP) working paper, Conflict and Gender Norms, Mark Dincecco, James Fenske, Bishnupriya Gupta, and Anil Menon investigate whether exposure to conflict in India’s pre-colonial era, when battles were fought with physically demanding weapons such as bows and swords, created a preference for male children which still endures today.

The team geolocated battles and other conflicts between 1000 CE and 1757, when the Battle of Plassey established the dominance of the British East India Company, to create a measure of a location’s exposure to pre-colonial conflict.

This measure was compared to three measures of male-favouring gender norms: the sex ratio of the population; data on the sex of individual births; and the prevalence of crimes against women in early 21^st century.

The analysis found a robust positive relationship between conflict and male-favouring norms: districts that experienced greater exposure to pre-colonial conflict have more male-based sex ratios in the present-day population; and have a greater number of crimes against women.

But how is it possible for experiences from centuries ago to influence attitudes towards women today?

Folk tales and religious traditions can pass on cultural beliefs around gender norms and hand them down through generations. In Uttar Pradesh, researchers have recorded a number of folk songs denigrating the birth of a girl child and the women who birth them, for example:

“She gave birth to a male child – that’s why she is sitting on the bed: she is giving orders to everyone in the house.

If she had given birth to a female child, she would be sitting on the doorsill; she would have fallen from everyone’s eyes.”

Traditional songs in the eastern and southwestern areas of India are much less negative about women.

The researchers found positive relationships between exposure to conflict and folk tales with negative attitudes to women and exposure to conflict and a higher proportion of male temple gods; and exposure to conflict and a greater chance that women leave their home villages after marriage.

To test whether gender norms endure even if people migrate, the authors repeated the analysis using individuals’ mother tongue rather than geographic location, as the major languages of India typically reflect ancestry in specific regions. This analysis showed that male-favouring gender norms persist even after migration to areas that do not have historic exposure to conflict.

Commenting on the findings Professor Gupta said:

“Male-favouring gender norms are prevalent in many parts of the world today. They persist in India despite its recent economic growth, which is generally regarded as something which leads to more positive outcomes for women.

Our study provides new insights into the origins of these attitudes, focusing on the role of inter-state military rivalry and warfare.

The relationship which we have documented between exposure to conflict in pre-colonial times and cultural norms that favour men helps to explain why there is such variation in the proportion of missing women between different parts of India.

The evidence which we have found on the historical persistence of these attitudes also suggests that economic development alone may not resolve India’s gender inequality challenges.”

Advice given by Professor Dennis Novy to the London Assembly Economy Committee has been reflected in the Committee’s formal recommendations to Mayor of London Sadiq Khan.

Professor Novy was invited to appear before the Committee on 11 Jan to answer questions and give informed insight into the impact of Brexit on London’s economy.

The Committee held the hearing in order to better understand the impact that leaving the EU has had on London’s economy to date, including asking whether sufficient time has elapsed to understand this impact and whether it is possible to separate the impact of Brexit from other challenges such as the pandemic and Russia’s full-scale invasion of Ukraine.

Among other topics, in his evidence Professor Novy highlighted the risks to businesses of all sizes created by post-Brexit regulatory divergence, and the need to develop a cohesive strategy for trade in services.

In her letter to the Mayor, Committee Chair Marina Ahmad quoted Professor Novy’s remarks on regulatory divergence and uncertainty, saying: “we believe this is a policy area the Mayor should take interest in and work proactively with the Government on. The review of the TCA in 2026 presents an opportunity to do this.”

The letter goes on to make a formal recommendation to the Mayor on this issue.

Recommendation 2: Ahead of the 2026 review of the EU-UK Trade Cooperation Agreement, the Mayor should work with London & Partners to build the evidence base for the effects of regulatory divergence on London-based businesses. He should use this evidence to lobby the Government to ensure that London-based businesses are not negatively impacted by regulatory divergence from the EU.

Professor Novy said: “I am very pleased to see that the evidence session, which was wide-ranging and thorough, has led to specific recommendations to the Mayor of London based on the research evidence which I and the other guests shared with the Committee.

“During my evidence I called on politicians to work in a cross-party way to develop a strategy that reflects the strengths of the UK and the London economy.

“I hope that the Mayor picks up this challenge.”
