Episode 6: ‘Hayek: A life, 1899 – 1950’. With Bruce Caldwell

In this episode, Juan Castaneda hosts Professor Bruce Caldwell, a renowned academic, Director of the Center for the History of Political Economy at Duke University who has co-authored the first volume of Hayek’s biography in 2022 (see details below). They explore Hayek’s life and journey up to 1950, towards becoming a leading classical liberal economist and social thinker.

More detail

The conversation begins at post-World War I Vienna, a city teeming with intellectual ferment and political and economic turmoil. Caldwell highlights the importance of understanding the historical context in which Hayek grew up, emphasising that the aftermath of war and the subsequent economic crisis and the hyperinflation episode played a significant role in shaping his ideas; in particular, Hayek’s deep interest in monetary issues, his scepticism of central planning and his advocacy for individual freedom and free markets. Hayek’s engagement with the ideas of socialism during his time as a student, is explored, as well as the impact of witnessing the rise of mass parties and the erosion of individual liberties.

Caldwell discusses Hayek as a classical liberal and not as a libertarian. Hayek did not deny the state to allow for a well-functioning society, but one we needed to put limits on. The discussion then shifts to Hayek’s publication of The Road to Serfdom (1944), which emerged in response to the growing popularity of socialism and the perception by many at the time that central planning was a means to achieve economic and social justice. Caldwell highlights Hayek’s argument that centralised control inevitably leads to the erosion of individual freedom. The discussion of these ideas was at the core of the foundation of the Mont Pelerin Society by Hayek in 1947.

Throughout the podcast, Caldwell emphasises Hayek’s commitment to understanding the complexity of the social order and the importance of spontaneous market processes. The conversation ends with Caldwell’s recommendations on Hayek’s works.

Episode 5: ‘Economic Affairs. An International Journal of Liberal Political Economy’ with Len Shackleton

Len Shackleton explains how the journal was founded by Arthur Sheldon, of the Institute of Economic Affairs (IEA), to provide an opportunity for those authoritative on the workings of markets to analyse events more promptly and crisply than is possible in the IEA papers. Since its birth in 1980, it has become increasingly international in its scope and readership.

More detail
Castaneda then questions how Economic Affairs has responded to the trend of mainstream economic papers becoming increasingly focused on methods, making them more difficult to read by non-specialists. Shackleton argues that Economic Affairs does not disregard articles with statistical analysis, though they are presented in a way such that a well-informed reader can easily identify and follow the main argument. Shackleton explains that the journal has a wide audience: a large number of whom are professional economists, but there is also interest from politicians, policy makers and journalists.

The discussion then turns to another trend amongst academic economics articles: a detachment from day-to-day economic issues. Castaneda questions whether Economic Affairs has followed this trend, and enquires what topics the journal typically features. Shackleton replies that the journal publishes three types of articles: (1) new research original articles, (2) discussion, more provocative pieces, and (3) a book reviews section and one long review article.

Castaneda then questions how relevant the classical liberal approach that Economic Affairs follows is to the understanding of Economics? Shackleton replies that whilst Economic Affairs does publish articles in this tradition, it isn’t an exclusive club, and they welcome articles approaching political economy from a range of different perspectives. The podcast ends with Shackleton offering advice to young scholars when assessing which journal to submit their manuscripts for publication: his major advice is to be aware of who you are talking to, who your audience is. Somebody reading your article is interested in your core message and the way in which you present relevant conclusions.

Economic Affairs is a peer reviewed journal published by the Vinson Centre at the University of Buckingham and the Institute of Economic Affairs, in collaboration with Hesperides University and Francisco Marroquin University, through academic publisher Wiley. It is edited by Prof. Len Shackleton. The journal content is available by subscription, though a substantial number of articles are open access. Further details can be obtained from:



Episode 4: ‘Trade and Development in Africa’. With Alexander Hammond

Alexander Hammond opens the discussion by explaining the benefits of trade. Through examining how long it would take for one individual to make a chicken sandwich from scratch, it becomes clear how dystopian (and much poorer and inefficient) a world without trade would be.

More detail

Juan Castaneda then questions why there is so much opposition to trade from policymakers across the world. Hammond explains that much opposition to trade is partly the result of companies lobbying governments to erect artificial trade barriers to protect them from foreign competition. Another reason for protectionist sentiment among policymakers is that tariffs can create direct revenue streams for governments, yet their costs are largely unseen. Hammond explains that common barriers to trade aside from tariffs include inadequate infrastructure and excessive regulation.

The discussion then turns to different standards and labour market regulations between countries, and whether this should restrict free trade. Hammond debunks the idea that richer nations are taking advantage of people in poorer countries by looking at opportunity cost: average incomes of people working in the agricultural sector and family or community run farms tends to be significantly lower than those working in factories or even sweatshops. This highlights that whilst labour market conditions in poorer countries may shock people in the developed world, they are preferable to other domestic job opportunities. Furthermore, Hammond states that trade can bring poorer countries a greater range of products at lower prices.

Castaneda draws attention to the ‘infant industry argument’ raised by the critics of free trade, and whether smaller countries can compete internationally without being protected and subsidised first. Hammond refutes this by stating that protected industries will ‘never grow up’ unless they trade internationally, and that government subsidies arbitrarily select winners. Hammond then explains how Africa has become significantly freer since the end of the Cold War, as many countries previously bankrolled by the Soviet Union became freer, and that this has correlated with greater economic development.

Finally, Castaneda asks whether aid is an appropriate alternative to free trade. To this, Hammond explains the problems of foreign aid through debunking the vicious cycle of poverty theory, an argument that helped create the modern aid industry. Hammond explains that many formerly rich countries have become poor (e.g. Venezuela) and vice versa. He concludes by explaining that an estimated 30% of aid does not reach its final destination due to corruption, and politicians spend too much valuable time coordinating aid.

Episode 3: ‘Adam Smith – A strawman for unfettered capitalism?’ With Mikko Arevuo

‘Adam Smith is credited as the father of modern economics for his work on systemizing economic activity as an independent discipline of political economy in his 1776 work The Wealth of Nations. WN has come to overshadow Smith’s earlier 1759 work The Theory of Moral Sentiments where he expanded on David Hume’s (1751) account of moral philosophy by developing the concepts of sympathy (or sympathetic imagination that enables us to grasp the situation and sentiments of others), and the impartial spectator (an observer of our own behaviour and that of the others) that culminated in the articulation of virtue ethics based on prudence, temperance, justice, benevolence, and self-command in commercial society. Smith’s political economy laid the foundations for modern economics, arguing that markets should be free from government intervention. However, Smith’s ideas about economics were not divorced from his moral philosophy. He believed that economics and morals were inextricably linked and that a healthy economy depended on a society of virtuous individuals’.

More detail

In our conversation with Mikko Arevou, we ‘address the mistaken interpretations of Adam Smith’s fundamental concepts that have been said to have had a corrosive influence on commercial behaviour’. Mikko argues that ‘a close reading of Smith’s work reveals that although he promoted free market competition as a prerequisite for wealth creation and limited government intervention in economic and social affairs, he was a critic of greed, the commodification and alienation of human relationships that resulted from division of labour, crony capitalism, and he was aware of the corrosive effect of inequality on human morality’.

Episode 2: ‘Monetary policy of the Bank of England’, With John Greenwood

Our conversation with John Greenwood provides a detailed discussion on the Bank of England’s policies in 2020-21 and their role in explaining the current inflation episode in the UK. Our discussion elaborates on John Greenwood’s latest contribution to the journal of Economic Affairs (February, 2023, pp. 53-72; to hyperlink to the journal’s page online, ), “The monetary policy strategy of the Bank of England in 2020-21: An assessment”.

More detail

Juan Castaneda starts the conversation suggesting that senior academics, policy makers, and central bankers do not seem to have a coherent theory of what causes inflation. John Greenwood then gives an overview of the current monetary policy of the Bank of England, which is based on an aggregate demand and supply model. The staff of the bank prepares estimates of aggregate demand, which is the spending side, and aggregate supply, which is composed of the potential outcome and the output gap. The output gap is the difference between the actual output and the calculated potential output. If the potential output is above the actual output, the bank might try to stimulate the economy. If aggregate demand exceeds aggregate supply, the bank will tighten policy by raising rates. However, quantifying all of this is challenging, especially in real-time. As John Greenwood concludes, while it is in part a Keynesian model it is certainly not monetarist.

John Greenwood then discusses the role played by the Bank of England in the creation of money during the Covid19 pandemic, mainly via Quantitative Easing (QE)  operations. These consist of the purchase by the central bank of assets such as government securities and potentially private sector bonds and securities by the central bank. In 2020 and 2021 the Bank of England purchased a large amount of guilts (i.e. government bonds), mainly from non-banks, resulting in the creation of additional reserves and new deposits in the banking system (i.e. money).

Why QE has now been inflationary and it wasn’t back in the aftermath of the Global Financial Crisis (2007-09)? This is a key question John Greenwood addresses in our conversation. In 2009 commercial banks focused on repairing their balance sheet and reducing bank lending, leading to subdued growth of money, broadly defined (including bank deposits). With QE central banks, in essence, ‘filled the hole’ left by commercial banks and managed to avoid a more profound fall in the amount of money. This low rate of growth of money broadly defined is what explains subdued inflation in those years. However, in 2020 and 2021, QE resulted in a significant increase in the amount of money, which explains the increase in nominal spending and ultimately in inflation, though with a delay.

The main proposition of the ‘quantitative theory of money’ is that there is a stable relationship between the quantity of money in the economy and nominal spending in the economy. If there is a change in the amount of money, in the longer run it will impact the price level: if too much money, that causes inflation, and vice versa. However, the Bank of England didn’t (doesn’t) use this rationale to assess the effects of the increase in the amount of money (which reached 15% on an annual basis between 2020 and 2021). There is roughly a  two-year delay between the policy change and inflationary figures. Instead the Bank of England seems to focus on the policy rate and not the change in the quantity of money when assessing inflation.

Overall, you will find in this episode a comprehensive overview of the monetary policy strategy of the Bank of England and the quantitative theory of money, and how the Bank of England has contributed to the 2021 – 2023 inflation episode in the UK.

Episode 1: ‘The search for stability’, with Geoffrey Wood

In our conversation with Professor Geoffrey Wood, we discussed some of the topics in his latest contribution to the journal of Economic Affairs (February, 2023, to hyperlink to the journal’s page online, ), with the title “The Search for Stability.” The first topic of discussion is the definition of what a financial crisis is and how it differs from other crises. The policies to  deal with financial crises were developed in the early/mid 19th century by the Bank of England during successive banking crises. The Bank of England realised that it was important to preserve the stability of the banking system as a whole since financial crises affect a large portion of the banks, and one firm’s failure can have a domino effect. The classic example of this is the Great Depression.

More detail

The discussion then delves into the different types of banking crises: a capital crisis and a liquidity crisis. A capital crisis occurs when there is a sudden drop in a bank’s capital, for example when a large loan goes wrong. On the other hand, a liquidity crisis is when a bank is solvent (i.e. it has enough capital) but cannot meet all its payment obligations. In the event of a run on a bank this can precipitate a loss of confidence in other banks and thus provoke the collapse of the entire banking system.

The conversation then moves to how central banks should respond to a liquidity crisis. Professor Wood suggests that the central bank should lend freely to any affected bank to prevent a crisis, provided that the bank in crisis has enough assets to borrow money from the central bank. The central bank should lend on a higher interest rate to account for the greater risk incurred by the bank in crisis, even if the collateral provided is not ideal. Professor Wood makes it clear that the emphasis should be put on the stability of the whole financial system; thus any firm should be allowed to fail, as long as there is a legal mechanism in place to ensure that the process is orderly, which is the case in the UK and the US.

Finally, regarding the new regulations approved by both international and national regulators to prevent a financial crisis, Professor Wood argues that creating a framework on how to deal effectively with crises, rather than making institutions similar in terms of their balance sheets, is a better approach. Our conversation ends with a summary discussion on the importance of understanding the different types of financial crises and how to respond to them effectively.
