How does culture affect development policy, and how does development policy affect culture? If we don’t take account of cultural norms or fail to learn about how they interact with well-intentioned polices, then this gap in our knowledge may be undermining development projects. Can better measurement and collaboration with other social sciences fill these gaps? A new paper investigates what we know about the culture, policy, and economic development, and Natalie Bau of UCLA, Sara Lowes of UC San Diego, and Eduardo Montero of the University of Chicago tell Tim Phillips about the potential, and pitfalls, of research into culture.
With record levels of armed conflict around the world in recent years, the study of conflict has gone from being a niche corner of economics into a thriving discipline that learns from, and interacts with, development economics. Rigorous empirical research on conflict is, however, relatively recent.
The Reducing Conflict and Improving Performance in the Economy (ReCIPE) programme aims to provide a better understanding of the links between conflicts, economic growth, and public policies. this week we speak to Dominic Rohner (Geneva Graduate Institute), the Research Director of the programme, and Oliver Vanden Eynde (Paris School of Economics), the Head of Engagement about their new research that attempts to link the attributes of countries to the types of conflict they experience, how economic methods can advance our knowledge of conflict and the policies to reduce it, and what the work of ReCIPE can do to influence policy around conflict and development.
In 2025, the International Food Policy Research Institute (IFPRI) is 50 years old. “Lessons and Priorities for a Changing World”, its 2025 Global Food Policy Report, runs to just under 600 pages and covers the last five decades of progress in improving the world’s food systems – but also the challenges that remain, and the need for policy to keep evolving if we are going to build sustainable, healthy food systems.
Johan Swinnen and Purnima Menon of IFPRI talk to Tim Phillips about the importance of agrifood resilience. With changes in the global economy, the equity and effectiveness of these food value chains will affect the livelihoods of billions of people. But has the progress in the last 50 years stalled?

What happens from the moment goods are manufactured or harvested, until they are bought by consumers? As we know from experience, most of the things we consume reach us having been bought and sold, sometimes many times, by intermediaries – most of us don’t order a phone from the factory. Many interventions designed to increase the welfare of consumers in developing economies are designed to shorten these supply chains by cutting out those traders in the middle. But what happens when you do that in the real world?
Meredith Startz of Dartmouth College tells Tim Phillips why the story of what intermediaries deliver, and even their effect on the prices consumers pay, is more nuanced than our economic models often suggest.
Like all of us, healthcare providers bring their biases to work. But if those biases result in a reduced level of care for their patients, how can we correct them?
An innovative experiment in three very different countries attempted to reduce bias in contraceptive care for women. Zachary Wagner of USC and Manisha Shah of UC Berkeley were two of a multidisciplinary team that implemented program and evaluated the results. They talk to Tim Phillips about how biases shape contraceptive care, the methods that can help us to understand why they arise, and the challenges of creating a program that can work in different cultural and religious settings.
In the second of our two podcasts with Francis Annan of UC Berkeley on his research on mobile money first in Ghana, then beyond, Tim Phillips discusses how he worked with commercial providers, not just to set up the RCTs designed to investigate the extent and reduce financial fraud, but to ensure that the insights could be scaled up.
While contacting sceptical commercial providers can often meet with little or no response, he says, the ability to frame research in a way that makes them realise the commercial value as well as the social value can get, and keep, their attention – and lead to a long-run partnership that achieves more than working independently or through regulators.
How can we design digital financial inclusion that minimizes fraud and maximises the benefit to the community in rural, low-trust, or cash-heavy economies? That’s the question posed by three studies of how mobile money works, or sometimes does not work, in Ghana’s villages. The author of those three studies: Francis Annan of Berkeley.
In part one of a two-part VoxDev Talks special, Tim Phillips talks to Francis about this research, which has been a big part of his working life since he was a graduate student, the innovative interventions to minimise fraud and misconduct from the agents who supply mobile money, and what this tells us about how to protect consumers in remote locations.

Stigma, shame and social norms around menstruation can prevent women and girls managing their periods with dignity and hygiene in low-income settings. So how can we provide information, influence those norms, and change behaviour to improve women’s health and well-being? Silvia Castro of LMU Munich and Kristina Czura of University of Groningen have conducted extensive field research in Bangladesh and other countries.
They tell Tim Phillips how we can reduce the stigma and taboo around menstruation and give women and girls the information they need at home, at school, and at work.

There is a long history of using “edutainment” – mass media storytelling, to pass on information about important social issues, and even to try to change behaviour. But does this work, and in what circumstances can it help?
Amber Peterman of UNICEF has just published a review of what we know about edutainment’s power to reduce violence against women and children. She talks to Tim Phillips about its track record in changing attitudes to problems such as FGM and child marriage, and the potential of edutainment in social media and even graphic novels.
Many developed countries are creating immigration policies designed specifically to attract the most talented migrants. We often assume that when those skilled and educated citizens migrate from low-income countries in search of high-paying opportunities, it causes a “brain drain” in their home countries, delaying or hobbling development. A new article in the journal Science puts that assumption to the test and finds that there is also the possibility of a brain gain at home, as investments in education, remittances, and the contribution of the diaspora to investment and changing norms can more the compensate for the loss of skills.
Cátia Batista of Nova School of Business and Economics and Caroline Theoharides of Amherst College are two of the authors of the article, and they tell Tim Phillips about what the potential for brain gains, but also the policies that are needed to make sure this happens.

In the second of our special episodes recorded at the 5th annual STEG conference, Lucas Conwell of UCL talks to Tim Phillips about how the private minibus networks, such a distinctive feature of urban transit in developing country cities, can improve their service when there is little room for public investment or regulation.
If you have ever tried them, they can seem chaotic, but would require large or small policy tweaks to make them work efficiently, and what would those tweaks be? Lucas has mapped both the service and the opinions of passengers for Cape Town’s public transit minibuses, and discovered that minimal intervention could improve services, increase security, and decrease wait times.

This week on VoxDev talks we have two special episodes recorded at the 5th annual STEG conference. STEG is a research initiative that aims to provide a better understanding of structural change, productivity, and growth in low- and middle-income countries.
For many economies in the Global South, fossil fuel extraction has been both a blessing
and a curse. Nowhere more so than Nigeria, where oil production generates huge
revenues, but also creates an environmental and social burden for the people who live in oil producing regions.
Arinze Nwokolo of Lagos Business School has investigated one aspect of this burden: how gas flaring that occurs as part of the oil production process affects local agriculture. He talks to Tim Phillips about the dramatic impact it has on agricultural productivity, and how the policy alternatives can change those outcomes.

In October 2024, Prabowo Subianto became president of Indonesia. He inherits the “Golden Indonesia” vision: By the time the country celebrates 100 years of independence in 2045, it aims to be one of the five largest economies in the world. But if Indonesia remains dependent on commodity exports like palm oil, coal, natural gas, and rubber, does it risk getting stuck in the “middle income trap” – too wealthy to compete with low-wage nations, but without the human capital or technology to become a HIC?
Chatib Basri is an economist and former finance minister of Indonesia. He tells Tim Phillips about the industrial policies needed to accelerate Indonesia’s economy and diversify its exports, and the challenges if Indonesia does not accelerate its growth.

It was almost business as usual at the Education World Forum in London last month. At the world’s largest annual gathering of education and skills ministers, this year’s theme was & "Building stronger, bolder, better education together." But the context was far from routine. The conference took place against a backdrop of global funding cuts to education programmes—the Institute for Economics and Peace estimates that more than 35 million children around the world depend on foreign aid for their basic education. How can policy be strong, bold, or better in the face of these cuts?
Ben Piper, Director of Global Education at the Gates Foundation and a panellist on the
Global Education Evidence Advisory Panel (GEEAP), was at the conference, meeting
education ministers and discussing these problems with them. He tells Tim Phillips that, at a time when funding is scarce, foundational learning projects deliver cost-effective results for policymakers, and huge benefits for children.

From Brazil, we bring good news for poverty reduction: Brazil’s formerly sky-high wage
inequality is not quite so sky-high anymore. From 1995 to 2015 Brazil became a more equal society, a trend that contrasts with rising inequality during that time in high-income countries. A soon-to-be-published article in the Journal of Economic Literature reviews the research that estimates the reduction, discovers the factors that have contributed to it and the mechanisms that have driven it. Alysson Portella of Insper tells Tim Phillips why there is no silver bullet that policymakers can use to reduce inequality, and why both implementing and evaluating policies in Brazil can be even more challenging than in other countries.

AI’s boosters claim that it is going to revolutionize growth in the developing world. The
sceptics, many of whom are economists, point to a thin evidence base and the risk of
unintended consequences. This is not an easy question to research, not least because the underlying technologies are literally changing by the day, while the pace of academic research is often measured in years. One of those researchers is David Yanagizawa-Drott of the University of Zurich. We spoke to him about his hopes and fears for AI, how he keeps his research relevant, and how economists can influence the future applications of AI.

The Reducing Conflict and Improving Performance in the Economy (ReCIPE) programme
was established in April 2024 as a CEPR research initiative to provide a better understanding of the links between conflict, economic growth, and public policies. One of its themes is the link between conflict and hate speech, social media use, media bias, and propaganda. We need to know more about how media has influenced violence,
xenophobia, and recruitment for armed groups. Also, how we can use media sentiment to predict a rise in the risk of violence.
Maria Petrova of the Barcelona School of Economics and Augustin Tapsoba of the Toulouse School of Economics are the theme leaders. They spoke to Tim Phillips about the challenges of researching the impact of media, especially social media, on conflict, and what recent research has discovered.
As aid programs are cut across the developing world, the focus falls on what investors can do to help create economic growth. Someone who knows all about impact investing is Yonas Alemu, the founder of Lovegrass Ethiopia, which creates products from teff, a gluten- free grain that's native to Ethiopia and sells them across the world. Yonas abandoned a successful career in investment banking in London to create a business in the country of his birth. He spoke to Tim Phillips about how entrepreneurship can stimulate positive change across Africa and how negative stereotypes of Africa’s dependency on aid discourage investment.

Millions of people around the world have no access to sanitation. They defecate in the open, or in facilities where it’s hard to avoid human contact, unavoidably spreading disease. One of the Sustainable Development Goals that you don’t hear about so much is the call to end open defecation by 2030. What progress are we making, and what health improvements are we seeing so far? In the latest of our episodes based on J-PAL’s policy insights, Karen Macours of the Paris School of Economics, also co-chair of J-PAL's Health Sector, tells Tim Phillips about how we can achieve this development goal, why it’s not a quick fix, and the surprising results of research into the health benefits of improving sanitation.

We often talk about providing not just jobs, but decent jobs, in developing countries. But in many parts of the world, workers still have incredibly harsh working conditions.
There have been interventions at the firm level to create safer workplaces, better health,
higher job satisfaction. But have they succeeded? And, if these policies succeed in raising worker well-being, is there a cost or a benefit for the employer?
In the latest in our collaborations with J-PAL to discuss their policy insights, Achyuta
Adhvaryu, UC San Diego about their review of the research into worker well-being, the
policies that encourage firms to improve it, and the outcomes for employees and employers alike.
