"Likes" fuel social network use
2021-03-02: What drives social media users to post almost compulsively and at a high cadence? A team led by researchers from the University of Amsterdam with the participation of Zurich neuroeconomist Philippe Tobler analyzed more than one million posts on various social networks. The goal was to find out how "likes" influence behavior. The more "likes" social media users receive for their posts, the more frequently they post. This pattern closely matches the so-called learning theory. This states that behavior is not only reinforced by reward, but also adapts to reward frequency. The pursuit of virtual acclaim on Instagram and the like revealed behavioral-psychological parallels with animals that are beckoned by a food reward. Rats that receive food when they press a certain button operate that button more often or less often, depending on how much food they receive. If there is a lot to eat, they will press the button repeatedly and at shorter intervals.

President Biden's plans to revive U.S. manufacturing after China shock
2021-03-02: The article in the New York Times discusses the factors and people that have shaped the American economy over the last few decades. U.S. manufacturing was hit hard when China entered the global market, with far-reaching consequences. Today, many economists argue that the so-called China shock was a historical anomaly, driven by the rapid industrialization of a very large and very poor country, and that it was mostly over by the early part of the last decade. “Since then, one also sees that trade growth slowed down considerably, at the same time as in the U.S. the loss of manufacturing jobs basically ended,” the article quotes David Dorn.

The Cost of Motherhood
2021-02-25: A large part of the income gap between women and men is due to motherhood. In Austria, Germany and Switzerland, this child penalty is twice as high as in Scandinavian countries, Josef Zweimüller shows in a recent paper. In an interview with Der Standard he explains which factors promote this inequality and why the expansion of external childcare services has done little to reduce the income gap.

Disposition for risk-taking is mapped in the brain
2021-01-29: There is a common genetic and neurobiological basis for risky behavior – the genetic disposition for risk-taking is mapped in several areas of the brain, a recent study by Gökhan Aydogan, Christian Ruff and Todd Hare shows. The study is the first to combine genetic information and brain scans from more than 25,000 people. Among other things, the researchers examined the relationship between individual differences in brain anatomy and the propensity to engage in risky behavior. “We found both functional and anatomical differences,” says Gökhan Aydogan.

The link between economic crises and political ruptures
2021-01-22: When do economics crises have destabilizing political effects? The Economist looks back at some historic crises and refers to a paper by Alumnus Sebastian Doerr and Hans-Joachim Voth, examining one of history’s darkest chapters. The Depression enabled the Nazis’ rise to power. However, the paper finds that economic pain was not the only factor that sent voters into the Nazis’ arms. The authors note the critical importance of the narrative surrounding the felling of two major German banks during the banking crisis in 1931.
What makes a healthy taxation system?
2021-01-22: The Chilean Diario Financiero interviews Florian Scheuer on taxation in general and specific challenges Chile faces. The main ingredients for a healthy taxation system are progressive taxation on consumption, income, wealth and capital gains, profits and inheritance. Chile has seen a number of changes to its taxation system over the last few years. Are such inconsistencies detrimental? “In principle, economic growth and prosperity benefit from a reliable and stable institutional framework, and this includes tax policy”, Florian Scheuer explains, “however, the tax system also needs to adapt to economic shocks and medium- to long-term changes in the economy.”

Fiscal federalism weakens redistribution
2020-12-16: Florian Scheuer discusses wealth and redistribution and takes a critical view of the Swiss tax system: "Even a very progressive tax system, i.e. one in which the tax rate rises sharply with income, doesn't do much good if those with the highest incomes cluster in municipalities where they have to pay very little. We observe that, as a result, taxes fall above a certain income level instead of continuing to rise." Efforts to change this fail because the middle class believes that their children could become rich. This makes the middle class the best partner of the rich, which is why it is subsidized by the state in many ways,e.g. most recently in Germany with the home ownership subsidy.

Christian Ruff contributes to URPP Adaptive Brain Circuits in Development and Learning
2012-12-04 Christian Ruff is co-initiator and contributor to the University Research Priority Program (URPP) Adaptive Brain Circuits in Development and Learning (ABCDe). The project aims to improve our understanding of the physiological and pathological mechanisms underlying brain circuit development and learning behavior.
One core aspect of the URPP is to relate human to animal learning – and back. In this project, Christian Ruff’s team at the Zurich Center for Neuroeconomics will be contributing by linking human circuit functions to animal models. This research will support the translation of mechanistic insights from basic research into the human clinical setting. The findings will allow improvements in the diagnosis of children with developmental delay, specifically developmental dyslexia, and provide novel therapeutic strategies.
Considerations on payment for participants in vaccination trials
2020-11-24: How much compensation should be paid to people who voluntarily let themselves be infected with a virus as part of vaccine research? Today, the payment of study participants is limited based on ethical considerations. However, Sandro Ambühl's research shows that participants assume that tests are paid according to their risk. This assumption can lead people to underestimate the risk and sign up for trials they would not have wanted to take part in. At the same time, overpaying can lead to false incentives. Alternative solutions are needed.
Various auction formats explained with practical examples
2020-11-18: Auctions are not only held for works of art or your old skis on Ricardo. Fishing licences, mobile phone frequencies and government bonds are also auctioned. Since a lot of money is at stake in these auctions and some conditions must be met during the auction, designing these auctions in the most efficient way is a key requirement. The American economists Paul Milgrom and Robert Wilson have significantly contributed to the success of today's auction formats with their scientific work and were awarded the Nobel Prize for Economics in October 2020.
In this article Nick Netzer, Marek Pycia and Sven Seuken (Department of Informatics) present practical examples of the various auction formats in an everyday view.

The expansion of external childcare is not enough
2020-11-12: Women often suffer significant income cuts after the birth of a child. An often voiced demand is that the number of childcare places needs to be increased. However, a recent study by a group of researchers around Josef Zweimüller shows that an increase in crèche places alone does not have an impact on mother’s income. The study focuses on Austria the country saw numerous family-related reforms over the last 60 years, which now allow the researchers to examine the influence of the expansion of crèche places. "The expansion of childcare places seems to substitute other forms of care, for example by grandparents," Josef Zweimüller notes. However, in communities where the provision of childcare was has been above average for a longer time, the loss of income for mothers is lower.

The dangers of the Google-Fitbit deal
2020-11-02: The EU Commission for Competition needs to make a decision on the Google-Fitbit deal by December 23. There a numerous concerns that allowing for Fitbit’s data gathering capabilities to be put in Google’s hands creates major risks. The combination of Fitbit’s health data with Google’s other data creates unique opportunities for discrimination and exploitation of individuals in healthcare, health insurance and other sensitive areas, with major implications for privacy too. Gregory Crawford and Economists around the world agree that preventing bad mergers is a key tool for competition policy vis-a-vis acquisitive digital platforms. In a recent VoxEU column and a number of articles, they emphasize that “the European Commission and other authorities should be very sceptical of this deal, and realistic about their limited ability to design, impose and monitor appropriate remedies”.
Continuous contributions to the pandemic discourse

Florian Scheuer explains the open letter to the Federal Council, signed by 60 Swiss economists. In it they make the case for a second shutdown in Switzerland. "The costs of lockdowns are often calculated by comparing them with economic activity before the pandemic. But that is the wrong comparison. Because now that the virus is raging, people are making changes in their own behavior that are damaging the economy". Link to interview on SRF Radio (9.11.20)
Unemployment benefits have little influence on wages
2020-10-14: Wage setting models often use the value of non-employment as a worker’s outside option. Under this assumption, the value of non-employment becomes a key determinant of wages. A recent paper co-authored by Josef Zweimüller and published in the Quarterly Journal of Economics uses Austrian data on changes in the level of unemployment insurance (UI) benefits to measure the effect of non-employment on wages. While the widely used Nash bargaining model predicts a sensitivity of $0.24–$0.48 per $1.00 UI benefit increase, Josef Zweimüller’s results show a response of less than $0.01 per $1.00 UI benefit increase. These findings point to the relevance of models in which wages setting is insulated from the value of non-employment.
