Terms of use: Documents inIZA Discussion Papers often represent preliminary work and are circulated to encourage discussion. Citation of such a paper should account for its provisional character. A revised version may be available directly from the author. Results show that an editor's former PhD students and faculty colleagues experience an increase in their publication outcomes when this editor is in charge of a journal. The analysis of articles' citations suggests that connections ultimately improve the quality of published papers.JEL Classification: A1, I23, J24

Social Ties in Academia: A Friend is a Treasure *This paper employs a unique dataset on articles, authors and editors of the top general interest journals in economics to investigate the role of social connections in the publication process. Ties between editors and authors are identified based on their academic histories. Results show that an editor's former PhD students and faculty colleagues experience an increase in their publication outcomes when this editor is in charge of a journal. The analysis of articles' citations suggests that connections ultimately improve the quality of published papers.

We investigate how the salience of an ethnic minority affects the majority group’s voting behavior. We use the increased salience of Muslim communities during Ramadan as a natural experiment. Exploiting exogenous variation in the distance of election dates to Ramadan over the 1980–2013 period in Germany, our findings reveal an increased polarization. Vote shares for both right- and left-wing extremist parties increase in municipalities with mosques when an election takes place shortly after Ramadan. We use survey data to provide evidence on mechanisms: Ramadan increases respondents’ perceived share of the foreign-born population and emphasizes cultural dissimilarities, ultimately worsening attitudes toward Muslims.
