    Common factors of withdrawn and prohibited merger cases in the European Union
    (Helmut-Schmidt-Universität / Universität der Bundeswehr Hamburg, Fächergruppe Volkswirtschaftslehre, 2020)
    Bernhardt, Lea Marleen
    ;
    In this paper, we analyse the final decisions for merger cases prepared by the European Commission (EC) since 1990 and build a unique subsample for all non-cleared cases. These incorporate all merger notifications which were either withdrawn by the notifying parties or have been prohibited by the European Commission.We find a sudden decline in prohibitions and withdrawals of cases since 2002 and explore three judicial defeats of the European Commission as determining factors behind these developments. We also find a higher likelihood of withdrawal or prohibition if cases are registered in sectors which incorporate firms in the business of information and communication or transportation and storage. When classifying the documents with a supervised machine learning algorithm, we are able to automatically identify the cleared versus the non-cleared cases with over 90% accuracy. Finally, we find that network effects, high market shares and the risk of collusion are the main competitive concerns which contribute to prohibition decisions in the information and communications sector.

    Watchdog or loyal servant?: political media bias in US newscasts

    We investigate if four leading, electronic news gathering organizations in the US - ABC News, CBS News, FOX News, and NBC News - fulfill their role as the fourth estate in the US democracy. Our analysis, using the Political Coverage Index (PCI) introduced by Dewenter et al (2020), is based on the tonality of their political coverage using 815,000 human-coded news items from 2001 through 2012. For our econometric analysis, we use panel regressions with media and time fixed effects. To account for endogeneity, we cut time spans around national elections out of our data. In the remaining data, elections can be seen as a purely exogenous event. Focusing on the entire media set, we find robust empirical results for an anti-government bias in media reporting: Under Republican presidents, political coverage tends to be more liberal, whereas it tends to be more conservative if the president is a Democrat. However, when focusing on each single news organization, interesting differences emerge: For CBS News and NBC News, we find robust empirical evidence of anti-government-bias. In contrast, FOX News is always much more critical of Democrats than of Republicans. Hence, FOX News can be seen as a more loyal servant to one party rather than acting as the fourth estate. In addition, we find no evidence that ABC News significantly changes its position depending on the presidency. Although descriptive statistics show a certain tendency toward government-critical reporting by ABC News, the variation is not statistically significant.

    Can media drive the electorate?: the impact of media coverage on party affiliation and voting intentions
    (EcoAustria - Institute for Economic Research, 2018) ;
    Linder, Melissa

    As the rise of populist and right-wing political movements is connected to extensive media coverage, the question arises whether media report more on political parties because of their success or if their success is caused by media reports. To tackle this question, we investigate how media coverage affects short- and long-term political preferences, namely party affiliation and voting intention. For our empirical analysis, we merge 14 years of human-coded data obtained from leading media in Germany with results of the comprehensive German Politbarometer survey from February 1998 through December 2012. To account for endogeneity, we employ instrumental variable estimations. In addition, we control for a multitude of (internal) personal characteristics, such as age, and gender, as well as for (external) macroeconomic variables, such as business climate, unemployment, and inflation. The results show that media coverage of a political party has a positive and significant effect on the shortterm voting intention for this party. When media outlets cover a political party more positively, the electorate has a greater tendency to vote for it. However, for long-term party affiliation, the effect vanishes. This is consistent with the economic theory. Long-term preferences are stable and, thus, contemporary events, such as media coverage, hardly affect supposedly stable preferences. However, in the long-term, party affiliation might also be affected.
