Marcel Garz


I am an assistant professor of economics at Jönköping University. Most of my work focuses on the economics of news markets, especially from an empirical perspective. I am particularly interested in issues with political implications, such as media slant and negativity. My research is often based on panel data and emphasizes the identification of causal effects.

Funding for project on Swedish newspaper markets

The Swedish Competition Authority has approved funding in the amount of approx. 180,000 euro for a project of mine entitled “Media Competition and Media Slant in Swedish Newspapers” (with Jonna Rickardsson). The project investigates how competition in local media markets affects the diversity of opinions in newspaper coverage. Specially, we (1) construct an index of ideological slant, (2) investigate which motives of media owners drive the slant, and (3) estimate the causal effect of competition on slant. The results aim to inform the debate on media regulation, with a focus on press subsidies and the measurement of media concentration. Posted: Oct. 03, 2019

4th Economics of Media Bias Workshop

After a successful start of the series in June 2015, the fourth Economics of Media Bias Workshop will take place on February 21-22, 2019, in Berlin, Germany. Eliana La Ferrara (Bocconi University) will deliver the keynote speech. The workshop, which is organized by my colleagues and me, addresses the forms, causes, and consequences of media bias, especially in news markets. The program can be downloaded here.

Investigating the “Hoeneß effect”

In a new study, my co-author and I investigate whether press coverage on celebrities with tax issues affects the behavior of other tax payers. We compile an original data set for Germany, including regional information on the amount of tax payers using amnesty regulations to voluntarily disclose taxes they have evaded. The data set also includes counts of news reports published by 6 national and 54 local newspapers that address celebrity tax evaders who were publicly tried between January 2010 and June 2016. To identify the causal effect, we use exogenous variation in the reporting, resulting from disasters and terrorist attacks that coincide with the celebrity trials. Instrumental variable estimates suggest that an increase in news coverage by the amount of an average trial raises participation in the tax amnesty program by approximately 22.5%. Posted: Sep. 1, 2017 (updated: Sep. 4, 2018)

Research Network obtains funding from the German Research Foundation (DFG)

My colleagues and I have been working on topics related to media bias for some time already. The German Research Foundation (DFG) recently agreed to support a proposal for an international, scientific network. The Research Network Economics of Media Bias promotes the discussion of ideas and work in the area, and it aims at integrating young researchers by connecting them with more experienced economists. As part of the network, it will be possible to continue the series of workshops “Economics of Media Bias”. Posted: Apr. 14, 2016
