Vita

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.

Slant of German News Outlets on Facebook

In a current working paper, my co-authors and I use text mining techniques to investigate the political bias of Facebook news pages. Our sample consists of 84 German news outlets, including all national newspapers and news magazines, several regional newspapers, as well as the most important newscasts and online news portals. We analyze the language of more than 2 million Facebook posts by these outlets and compare it with the language used by the main political parties – AfD, CDU/CSU, FDP, Grüne, Linke, NPD, Piraten, and SPD – in their election programs. Measures of text similarity allow us to approximate the ideological congruence between the Facebook news pages and the parties. For example, this measure can be used to determine the outlets’ position in the political left-right spectrum, as shown below. Posted: Nov. 30, 2017 (updated: May 18, 2018)

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%.

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
