10. 10: the 1981 blueprint for superstar wealth
20:47||Season 1, Ep. 10Our motivation:In 1981, Rosen introduced a mathematical model to analyse how the emergence of superstars would affect the income distribution. With the internet and globalization, his paper might be more relevant today than ever before. Abstract:The phenomenon of Superstars, wherein relatively small numbers of people earn enormous amounts of money and dominate the activities in which they engage, seems to be increasingly important in the modern world. While some may argue that it is all an illusion of world inflation, its currency may be signaling a deeper issue.1 Realizing that world inflation may command the title, if not the content of this paper, quickly to the scrap heap, I have found no better term to describe the phenomenon. In certain kinds of economic activity there is concentration of output among a few individuals, marked skewness in the associated distributions of income and very large rewards at the top.Reference: Rosen, S. (1981). The Economics of Superstars. The American Economic Review, 71(5),845–858. http://www.jstor.org/stable/1803469

9. 9: Schooling for profit and educational quality
01:33||Season 1, Ep. 9Our motivation: It is hard to measure the quality of education. This paper provides a novel approach by investigating how differences between for-profit and non-profit charter schools within the Swedish educational system affect pupils' earnings later in life. The results may also inform policymakers looking to improve the Swedish quasi-market for schooling. Abstract: I estimate the long-run earnings impacts of for-profit and non-profit charter high schools in Sweden, which as of 2023 enroll nearly half of all high school students in urban areas. Unlike in many other settings, there are no schools operating outside of the public system: all schools rely on equal public funding, cannot charge top-up fees, and are subject to the same regulation. Using a combination of regression discontinuity and value-added methods, I find that charter schools lower earnings by 2% on average—comparable to the returns to half a year of schooling in similar settings. My results suggest that for-profits generate these losses by hiring less-educated, lower-paid teachers, non-profits by specializing in arts and humanities programs. In a discrete choice framework using rank-ordered school applications, I show that students’ preferences are weakly related to schools’ earnings impacts and instead center on location and program offerings, which explain most of the charter market share.Reference: Berg, Petter. 2025.Schooling for Profit:Long-run Effects of Private Providers in Public Education.JobMarket Paper
8. 8: AI and the metaphors we use to understand it
04:26||Season 1, Ep. 8Our motivation: Mitchell provides an important think piece about how the metaphors we use to describe new technologies, in this case artificial intelligence (AI), shape the way we think about them. Sometimes the metaphors we use may even have unintended effects that may blur our understanding of both the technology and its societal impact.Abstract:The disagreements in the AI world on how to think about LLMs are starkly revealed in this diverse array of metaphors. Given our limited understanding of the impressive feats and unpredictable errors of these systems, it has been argued that “metaphors are all we have for the moment to circle that black box.”Reference: Mitchell, M. (2024). The metaphors of artificial intelligence. Science, 386(6723), eadt6140. Click here to read.
7. 7: Internal promotion or external recruitment of CEOs?
13:19||Season 1, Ep. 7Our motivation:Structural change is shaped by management and the recruitment of managers. This paper shows that internal promotions risk turning skilled employees into suboptimal managers and makes the argument that external recruitment of CEOs might make for better overall results.Abstract We study whether the quality of managers can affect public service provision in the context of public health. Using novel data from public hospitals in Chile, we show how the introduction of a competitive recruitment system and better pay for public hospital CEOs reduced hospital mortality by 8 percent. The effect is not explained by a change in patient composition. We find that the policy changed the pool of CEOs by displacing doctors with no management training in favor of CEOs who had studied management. Productivity improvements were driven by hospitals that recruited higher quality CEOs.Reference: Muñoz, Pablo, och Cristóbal Otero.2025. ”Managers and Public Hospital Performance”.AmericanEconomic Review 115(11):4040–74.
6. 6: Economic openness, government size and the welfare state
15:07||Season 1, Ep. 6Our motivation: Countries that are economically open towards the world tent to have high taxes and large welfare states. The standard explanation for this link, the so called compensation hypothesis, suggests that welfare states compensate for volatility caused by economic openness. In this note, Bergh challenges this explanation and describes how research on the link between economic openness and government size has changed over time. Abstract: This note describes how research on the link between economic openness and government size has changed over time. Early interpretations suggested that countries develop welfare states to compensate for volatility caused by economic openness (the compensation hypothesis). Recent findings have cast doubts on this interpretation. For example, more open economies are on average not more volatile, and economic openness does not unambiguously increase the social security demands from voters. Some recent studies suggest that economic openness is particularly beneficial for countries with high taxes and high-income equality. A re-interpretation of the compensation hypothesis is thus possible: Through trade, the citizens in large welfare states enjoy some of the benefits associated with cheap labour and high wage dispersion despite their domestic economy being characterized by high real wages, high taxes and a compressed wage distribution.Reference:Bergh, Andreas. 2021. ”The Compensation Hypothesis Revisited and Reversed”.

5. 5: Stress testing a quasi-market - Unintended consequences of the Swedish school voucher system
07:30||Season 1, Ep. 5Our motivation: This paper explores how quasi-markets compare to and differ from traditional markets in the case of the Swedish school voucher system, for example with relation to competition, innovation and structural change. In doing so, it contributes to moving discussions about privatization beyond the market or state dichotomy and highlights the need to address the particular issues of quasi-market design.Abstract: Quasi-markets are increasingly used in public service provision, yet they remain highly contested. This paper develops a conceptual framework grounded in economic theory to examine how quasi-markets differ from traditional markets along five key dimensions: (1) revenues, costs, and profits, (2) the matching of supply and demand, (3) competition, (4) structural change, and (5) rent-seeking. Assuming profit-maximizing behavior, we stress test the quasi-market model to explore how these structural differences shape incentives and influence outcomes. Applying the framework to Sweden’s school voucher system, we show that specific design features have led to unintended consequences that undermine service quality and conflict with the reform’s stated policy goals.Reference:Bergh, Andreas, and Joakim Wernberg. 2025. ”Stress Testing a Quasi-Market: Unintended Consequences of the Swedish School Voucher System”.

4. 4: In defence of "big tech"
14:49||Season 1, Ep. 4Our motivation: Varian (who is also Chief Economist at Google) addresses central criticisms against "big tech" and puts these issues into a wider scope of economic analysis. The paper adds to a more nuanced discussion about the role of large tech companies in the economy.Abstract: There is currently a great deal of interest in online competition, particularly involving large tech firms such as Google, Apple, Facebook, Amazon, and Microsoft (a group commonly known as “GAFAM”). In this essay I examine several issues involving these firms that have often come up both in the popular press and academic discussions. The goal of this paper is to examine the facts about the alleged seven deadly sins of tech: competition, innovation, acquisitions, entry, switching costs, entry barriers, and size. I argue that when you look at the facts, it is clear that competition among tech firms is working well, and this has yielded many positive outcomes for consumers and the economy as a whole.Reference: Varian, H. R. (2021). Seven deadly sins of tech?. Information Economics and Policy, 54, 100893.
