Episode notes
The conversation about evidence-based policy usually asks why good evidence isn't shaping decisions. But we should also be asking, is the evidence base itself actually worthy of shaping policy? In this episode of Ideas in Development, Rafe Meager – Associate Professor at the University of New South Wales and one of the leading meta-analysts in economics – explains why a single paper is not a proof, why we should learn to respect statistical noise, and why a result that holds in Kenya may or may not hold in Ghana. We walk through Rafe’s work aggregating microcredit RCTs, and their research…

S4 Ep4: Has development economics lost its way?
What should development economists be working on – and how does their work actually reach the people making decisions? Rachel Glennerster, President of the Center for Global Development, whose career spans the research and policy sides of development, joins Oliver Hanney to discuss her proposal for a radical simplification of aid, why she feels the micro-macro debate is largely a false one, the messy but vital process of building consensus, and what impactful careers look like in economics. In this wide-ranging conversation, we cover the Smart Buys evidence panels in education and how…

How global supply chains are built – and how to actually attract investment
Bill McRaith spent his career building supply chains – from 1980s Britain, to a factory in Panyu, China in 1990, to Ethiopia three decades later. He joins Oliver Hanney to explain what really attracts manufacturing investment to a developing economy, and why the model most countries are targeting no longer exists. In this wide-ranging conversation we cover why China’s industry grew; why responsive local governments beat tax holidays; the collapse of the wage gap; how Ethiopia was chosen as a beachhead; and why apparel remains the right first-mover industry for countries not yet on the…

Stefan Dercon on elite bargains and kickstarting economic growth (via the AUL Podcast)
Slightly different episode today. This is a repost of a recent episode on the Africa Urban Lab's podcast, in which Kurtis Lockhart (who co-hosted our Cities series) interviews Stefan Dercon - very much an episode I wish I'd recorded! You can watch this episode on the AUL's YouTube: https://www.youtube.com/watch?v=PGamGT2Z-RM&list=PL7c-FEmFCyL7z395iWUMlKNFzRyQTnLHH Stefan Dercon, Professor of Economic Policy at Oxford and former Chief Economist at the UK’s Department for International Development (now FCDO), joins Kurtis Lockhart to discuss what it takes for cities and countries to kickstart…

S4 Ep3: Moving billions towards evidence
In 2022, Dean Karlan became Chief Economist at USAID, tasked with steering the world's largest bilateral aid agency towards evidence-backed approaches. He left in 2025, as the agency was being dismantled, having moved roughly $1.7 billion of funding in the process. In this episode of Ideas in Development, Dean joins Oliver Hanney to discuss what evidence-based policy actually looks like inside a government institution; how his team picked their battles; why collaboration beat prescription; and where the limits of taking goals as given lie. They also cover the rise of embedded evidence labs…

S1 Ep5: How Ethiopia reformed its economy
Ethiopia is one of Africa's most ambitious bets on export-led manufacturing. It’s also the site of one of the continent's boldest recent macroeconomic reform programmes. In this episode of the Ideas in Development series on growth, Oliver Hanney and Kartik Akileswaran speak with Mamo Mihretu, the tenth Governor of the National Bank of Ethiopia and a former senior economic advisor to the prime minister. Having viewed Ethiopia’s economic change through various lenses, Mamo explains why Ethiopia's industrial parks succeeded where others stalled, what it took to attract anchor investors, and how…

S4 Ep1: The evidence gap on evidence use
Development economics has built a large empirical evidence base across a range of topics and policies – but how, when and where is it being used? We often assume that evidence will have an impact, but have surprisingly few answers to these key questions. Michelle Rao, a fellow at the Center for Global Development, joins us for the first episode of our new Ideas in Development series on evidence. We discuss her own research on these questions, which looks at whether evaluations of conditional cash transfers in Latin American and Caribbean countries influenced government spending. Then we…

Why Dani Rodrik changed his mind on manufacturing
This episode might sound a little different to normal, as it was recorded live. For decades, the standard prescription for growth in developing countries was clear: industrialise. Dani Rodrik used to argue that manufacturing was the escalator that could lift workers out of low productivity, and economies out of poverty. So what happens when the escalator stops working? Dani Rodrik, Ford Foundation Professor of International Political Economy at Harvard Kennedy School, joins Ideas in Development to explain why he has become a manufacturing skeptic, what the evidence from Ethiopia, India and…

Adopt AND innovate: How Brazil and Taiwan did both
How can developing countries catch up with the technology frontier? The standard debate frames it as a choice between adopting technology from abroad and innovating at home. Karthik Tadepalli argues that this dichotomy is false – and that two of the twentieth century's most striking development stories show why. In this episode of Ideas in Development , Karthik takes us from Taiwan's Industrial Technology Research Institute (ITRI), which licensed chip technology in the 1970s and went on to spin out UMC and TSMC, to Brazil's Embrapa, which unlocked an area three times the size of Texas for…

S3 Ep7: The perfect city?
What does a perfect city look like in a low- or middle-income country – and how do you get there? In the closing episode of our cities series, Ed Glaeser joins Kurtis Lockhart and Oliver Hanney for a wide-ranging conversation on what makes cities work. He sets out the three foundations every city needs (safety, mobility, education), why infrastructure without the right incentives and institutions fails, what 19th-century New York's cholera outbreaks teach Lusaka about water, why “bus good, train bad” still holds, and what the medieval European city has to offer sub-Saharan Africa's…

S3 Ep6: Cities of opportunity, not powder kegs
Are African cities a powder keg of restless youth – or the most promising place to build prosperity, peaceful politics and shared civic life? Leonard Wantchekon joins Ideas in Development to argue that African cities should be seen as a youth opportunity, not a youth problem. We discuss recent unrest in Kenya and Tanzania, his work showing that clientelism is overwhelmingly a rural phenomenon, and that deliberation and decentralisation are the institutional minimums African cities should be reaching for. Leonard then lays out what deliberation, decentralisation and a renewed urban culture…
