Political power of the press in the Weimar Republic
研究了魏玛柏林报纸发行量变化如何影响选民投票率、政党得票率和大众极化，发现发行量增加显著提高了外区投票率和极化程度，党派报纸对政党得票率有正面影响，且小报和大众报纸比精英政治报纸影响更大。
Abstract This paper examines how changes in newspaper circulation affected voter turnout, party vote shares, and mass polarization in Weimar Berlin. My empirical strategy exploits variation in the development of railway system across historical districts of Berlin, which influenced the circulation of newspapers. I find that an increase in newspaper circulation significantly induced higher turnout in fourteen outer districts and a higher degree of mass polarization. Partisan newspapers benefitted party vote shares, with stronger effects in federal elections than in local elections. The electoral influence of newspapers was driven by tabloids and mass newspapers, and not by elite political newspapers.
