The impact of university attendance on partisanship

Survey research shows that those with university degrees are more left-liberal along a number of dimensions than their peers without higher education. There is even some evidence to suggest a growing social and political cleavage centered on educational attainment. Yet, claims about the liberalizing effect of universities on political ideology and partisan identification rest on observational evidence where many assumptions are required to reach causal inference. This may account for conflicting findings in published research. Here, we employ a fuzzy regression discontinuity design situated in Romania, where students who pass a national baccalaureate exam are uniquely qualified to enter university. We find that university attendance causes more liberal party preferences along the cultural dimension of party politics-though not along the economic or left-right dimensions of party conflict.
