Economic Schools of Thought Explained | Dr Eamonn Butler | IEA Explained

In this Institute of Economic Affairs explainer, IEA Director Eamonn Butler discusses his new book "An Introduction to Schools of Economic Thought" and explores the major economic theories that have shaped our understanding of how resources are created and distributed. Butler examines the evolution from pre-classical economics through Adam Smith's revolutionary ideas about wealth creation, Karl Marx's labour theory of value, and the Austrian School's emphasis on individual choice and subjective value.The discussion covers how different schools approached fundamental economic questions, from the classical economists who challenged mercantilism to the Austrian School's critique of central planning. Butler explains the Keynesian revolution and its focus on government management of the macro economy, the Chicago School's monetarism and economic approach to human behaviour, and the neoclassical synthesis that attempted to mathematise economic theory. He also examines Public Choice economics and its sceptical view of government action, along with modern Behavioural Economics and its insights into human decision-making biases.Butler concludes by emphasising the importance of understanding these different schools of thought to grasp the historical context of economic ideas and to develop better frameworks for understanding economic life. He demonstrates how studying various economic approaches allows us to compare and contrast different explanations, potentially leading to improved economic thinking that builds upon the strengths of previous schools while addressing their limitations.

In this Institute of Economic Affairs podcast, Director of Communications Callum Price hosts a discussion with Executive Director Tom Clougherty and Editorial Director Kristian Niemietz on Labour's first year in government since their July 2024 election victory. The conversation examines Labour's economic performance, focusing on their growth mission, fiscal challenges, and supply-side reforms. They assess the government's struggles with their pro-growth agenda, the impact of their tax-and-spend budget that raised taxes by £40 billion while increasing spending by £70 billion, and the recent market turbulence around gilt yields and the pound.The discussion explores Britain's fiscal fragility, with debt interest payments exceeding £100 billion annually and conventional debt measures at 100% of GDP. Clougherty and Niemietz analyse how the government's inability to control spending within their own coalition has created a challenging political cycle, while examining whether Labour could adopt a supply-side abundance agenda similar to progressive movements in the US. They also address the housing crisis, noting how regulatory burdens are undermining development viability even in high-demand areas like London, and discuss the broader implications for economic growth and political stability.The conversation concludes with an examination of the re-emergence of socialism through figures like Jeremy Corbyn and international examples such as the recent electoral victory in New York, alongside practical policy discussions on fuel duty reform and price transparency in petrol retail. The hosts explore whether Britain faces a potential political realignment between nationalist populism and radical socialism, leaving classical liberals potentially marginalised, while considering the role of economic pressures like housing costs in driving support for more extreme political alternatives.

In this IEA podcast episode, Reem Ibrahim sits down with Professor Daniel Klein to unravel why Adam Smith-writing in 1776 as revolution erupted-predicted America would become "one of the greatest and most formidable empires that ever was in the world." Starting with Smith's remarkable GDP forecast that America would overtake Britain within a century (which proved dead right), they trace how the Scottish economist saw five liberal principles emerging in colonial thought that would drive unprecedented prosperity.Daniel walks us through Smith's analysis of American thinkers like James Otis and John Adams, revealing how subsidiarity, religious freedom, limited government, free trade, and virtuous governance aligned with Smith's own philosophical framework. The discussion explores milestone moments-from Thomas Paine's Common Sense appearing months before The Wealth of Nations, to Smith's 1778 memo showing intimate knowledge of American affairs, and his prescient observation that "from shopkeepers, tradesmen and attorneys, they are become statesmen and legislators."They examine Smith's radical insight about religious free markets - how Pennsylvania's pluralistic approach would produce "candor and moderation" better than established churches - and his conviction that America's "Don't Tread on Me" spirit reflected a healthy recognition that "government is the institutionalization of coercion." The conversation reveals hidden connections between Edinburgh Enlightenment thinkers and the Founding Fathers, showing how David Hume, Edmund Burke, and Smith himself favoured a "let them go" approach to American independence.Looking to today's politics, they debate whether Smith would recognise his liberal hopes in modern America's centralised state, vast bureaucracy, and eroding constitutional checks. From Trump's tariffs to expanding federal power, Klein argues Smith would be "a lot less optimistic" about America's trajectory toward the subsidiarity and natural liberty he once celebrated. If you care about classical liberalism, constitutional design, or why the Scottish Enlightenment saw America as humanity's great experiment, this conversation is for you.

In this Free the Power episode, IEA Andy Mayer sits down with writer and policy analyst Alex Chalmers (Trauma Machine Substack & Works in Progress) to unravel why nuclear power went from cheap and fast-to-build in the 1960s to eye-wateringly expensive today. Starting with fruit-fly radiation studies that won Hermann Muller a Nobel Prize and seeded the “no safe dose” dogma, they trace the cascading effects of U.S. weapons-testing mishaps, the birth of ALARA/ALARP regulation, and how a safety culture of ever-thicker concrete, cable and paperwork priced private builders out of the market. Alex walks us through milestone moments—the Castle Bravo fallout scare, Three Mile Island’s zero-fatality meltdown, and the UK’s decision to demand extra HVAC filters on an advanced boiling-water reactor that would have reduced public exposure by less than “the radiation you get from eating one banana.” The discussion sets out the hidden trade-offs regulators ignore (fossil-fuel particulates kill far more people than low-dose radiation) and why cost escalations of 176 % in a decade were largely debt-finance and delay, not engineering fate. Looking ahead, they debate ways to break the ratchet—smarter risk thresholds, local benefit-sharing, and the UK government’s new Nuclear Regulatory Task Force, which could let Britain reclaim its 1960s lead in affordable, abundant, low-carbon power. If you care about climate targets, energy bills or technological optimism, this conversation is for you. Like, subscribe and hit the bell to catch future Free the Power episodes.

In this Institute of Economic Affairs podcast, IEA Executive Director Tom Clougherty interviews Julia Willemyns, co-founder of the Centre for British Progress. The conversation explores the Centre's mission to promote pro-growth policies from a progressive perspective, examining how the centre-left can embrace economic growth and supply-side liberalisation. Willemyns discusses the organisation's evolution from UK Day One, their focus on addressing barriers to progress in Britain, and their belief that economic growth is essential for human progress and social mobility.The discussion covers key policy areas including planning reform, energy policy, and market dynamism. Willemyns advocates for "system resets" and regulatory simplification, drawing on examples from countries like Denmark's flexicurity model and innovative approaches to housing development in Houston and Israel. She argues for nuclear energy as crucial for Britain's energy independence and abundance, while critiquing both traditional left-wing approaches of regulation and redistribution, and the right's failure to deliver meaningful reform despite pro-growth rhetoric.The interview concludes with Willemyns' optimism about Britain's human capital and talent, while addressing the challenge of retaining high-skilled individuals. She emphasises the need for institutional reform that empowers rather than hollows out the state, advocating for policies that create opportunities for entrepreneurship and innovation. The conversation highlights the Centre for British Progress's approach of loving institutions enough to want them to work effectively, distinguishing their reform agenda from populist "slash and burn" approaches.

In this Institute of Economic Affairs podcast, Communications Manager Reem Ibrahim is joined by Executive Director Tom Clougherty and Editorial Director Kristian Niemietz. The conversation covers NHS productivity challenges, the government's welfare reform U-turn, and Labour's new industrial strategy. They examine how the NHS struggles to convert financial resources into productive medical inputs, despite having adequate funding compared to OECD averages, and discuss the need for decentralised decision-making and increased capital investment in healthcare.The discussion turns to the government's retreat on welfare reforms, particularly around Personal Independence Payments, after facing political pressure. They analyse the dramatic rise in disability benefit claims since the pandemic, with 63,000 people moving directly from student status to long-term sickness benefits without entering the labour market. The hosts explore why current welfare systems create perverse incentives that trap people in economic inactivity, and examine Steve Davies' proposals for moving beyond the welfare state towards community-based mutual aid solutions.The episode concludes with an examination of Labour's industrial strategy, which the panel views as ineffective government intervention in markets. They criticise the approach of subsidising specific businesses while maintaining high energy costs for everyone else, arguing that successful economic policy requires broad supply-side reforms rather than targeted industrial picking. The conversation highlights how governments lack the market knowledge necessary to effectively direct economic resources, referencing Hayek's insights on the knowledge problem in central planning.

In this Institute of Economic Affairs briefing, Communications Manager Reem Ibrahim interviews Dr. Christopher Snowdon, Head of Lifestyle Economics, about the government's consideration of new restrictions on alcohol advertising. The discussion examines why ministers are exploring these plans, potentially to create a "level playing field" with the upcoming junk food advertising ban, and Dr. Snowdon's analysis of why such restrictions would be ineffective and economically damaging. Dr. Snowdon presents comprehensive evidence challenging the effectiveness of alcohol advertising bans, citing Cochrane Reviews and real-world studies that show no meaningful impact on consumption or health outcomes. He explains how advertising primarily affects brand choice and market share rather than overall consumption levels, noting that even substantial increases in advertising spending over recent decades haven't changed drinking patterns. The conversation explores the flawed methodology of recall studies commonly used to justify such bans and why problem drinkers are unlikely to be influenced by advertising restrictions. The briefing concludes with an examination of the unintended consequences of advertising bans, including reduced competition in the alcohol industry and significant financial impacts on broadcasters and media platforms already struggling with declining advertising revenues. Dr. Snowdon argues that if products are legal, they should be advertised freely, provided the advertisements meet standards of honesty and decency. The discussion highlights the broader trend of successive advertising bans across multiple sectors and questions where such restrictions might end.

In this Institute of Economic Affairs Podcast interview, IEA Communications' Callum Price interviews Dr. Steve Davies, Senior Education Fellow, on the growing crisis of state welfare spending in the UK. Davies explains how the welfare bill has ballooned to approximately 12% of government expenditure (excluding pensions and healthcare), with incapacity and disability benefits alone expected to reach £100 billion by 2030 - up 25% since 2019. The discussion explores how Gordon Brown's well-intentioned income supplement system has created a welfare trap, where means-tested benefits impose effective marginal tax rates of 80% that discourage people from increasing their work hours or seeking better-paid employment. Davies argues that the current system is both financially unsustainable and socially destructive, trapping people in dependency while failing to address underlying structural problems like housing costs and low productivity. He critiques the limitations of technocratic reforms, explaining how attempts to tighten eligibility criteria often simply displace demand to other, more expensive programmes. The conversation covers the explosive growth in mental health problems among young people and the geographical mobility constraints caused by housing costs that keep people stuck in areas with limited employment opportunities. The interview concludes with Davies proposing radical alternatives to the current state-dominated system, including a return to mutual aid and voluntary collective action rather than traditional charity or market-based solutions. He advocates for either a minimal state safety net or universal basic services model, combined with locally-controlled, community-based welfare provision that draws on tacit local knowledge. Davies warns that without fundamental reform, the UK risks creating an even more punitive welfare system following a future financial crisis, and calls for honest political conversation about the severity of the challenges facing the current approach to social support.

In this Institute of Economic Affairs Podcast Interview, IEA Executive Director Tom Clougherty interviews Dan Neidle, founder of Tax Policy Associates and one of the UK's most respected tax experts. The conversation covers the fundamental problems with Britain's tax system, examining public misunderstanding of how tax thresholds work, the challenges of pro-growth tax reform, and why wealth taxes are likely to fail. They also discuss the absurd cliff edges in income tax that discourage people from earning between £100,000-£125,000, creating effective marginal rates of up to 62%. Dan explains why current tax policy is made through "political theatre" rather than rational design, leading to a system he describes as "pure rabbit" above £200,000 in earnings. The discussion covers the economic incidence of taxation, revealing how taxes legally paid by businesses often fall on workers and consumers. They examine specific reform proposals including full expensing for business investment, radical VAT base broadening, and replacing stamp duty with annual land value taxes. Dan also critiques popular wealth tax proposals, arguing they would apply punitive effective rates of up to 75% on a highly mobile group of around 10,000 wealthy individuals. The interview concludes with analysis of the government's likely approach to raising taxes in the autumn budget. Dan argues that while politicians prefer targeting "other people" with complex loophole closures, the most honest approach would be putting a percentage point on income tax rates. Throughout the conversation, both speakers emphasize areas where tax experts across the political spectrum agree on rational reforms, even while disagreeing on overall tax levels and the size of the state.

In this Institute of Economic Affairs Podcast, IEA Executive Director Tom Clougherty is joined by Managing Editor Daniel Freeman and Editorial Director Kristian Niemietz for a wide-ranging discussion covering three major policy areas. The conversation examines the spiralling costs and delays of HS2, which now has no fixed opening date despite ballooning to over £100 billion for a truncated route that no longer reaches Manchester or Leeds. They also debate whether classical liberals should abandon the term "liberal" in response to Rod Liddle's argument that the word has been captured by progressive movements, and conclude with an analysis of Donald Trump's proposed tax legislation extending the 2017 reforms. The discussion reveals how Britain's planning system makes infrastructure projects vastly more expensive than comparable European examples, with the French TGV between Tours and Bordeaux costing under €8 billion for the same distance as HS2's London-Birmingham route. The hosts argue that excessive consultation processes, environmental regulations, and multiple veto players have created a system where Britain struggles to build anything efficiently. On the liberal terminology debate, Niemietz pushes back against claims that "liberal" now means "woke," arguing that in Britain the term retains its classical meaning and that progressives themselves reject the liberal label. The Trump tax bill analysis highlights the contradiction between extending pro-growth measures from 2017 while introducing distortionary new provisions like exempting tips and overtime from taxation, plus car loan deductions for American vehicles only. Most concerning is the proposed withholding tax on foreign investment, which could undermine America's ability to attract international capital while simultaneously running massive deficits. The hosts suggest this reflects the administration's inconsistent approach to trade deficits and foreign investment, potentially threatening the dollar's reserve currency status that enables such fiscal flexibility.
