Age, Period and Cohort effects in the Decline of Party Identification in Germany

Party identification traditionally is seen as an important linkage mechanism, connecting voters to the party system. Previous analyses have suggested that the level of party identity is in decline in Germany, and in this article, we first expand previous observations with more recent data. These suggest that the erosion of party identity continues up to the present time. An age-period-cohort analysis of the panel data of the SOEP panel suggests that period effects are significantly negative. Furthermore, it can be observed that throughout the 1992-2009 observation period, education level and political interest have become more important determinants of party identity. Contrary to some of the literature, therefore, it can be shown that the loss of party identity is concentrated among groups with lower levels of political sophistication, indicating that the socio-economic profile of the group with a sense of party identification has become more distinct compared to the population as a whole. In the discussion, we investigate the theoretical and democratic consequences of this trend.

Partisan Dealignment in Germany: A rejoinder to Russell Dalton

The work of Russell Dalton has undoubtedly played a seminal role in the study of the relation between political sophistication and partisan dealignment. We furthermore acknowledge the presence of a consensus on the occurrence of lower levels of partisanship in Germany. Using panel data as well as pooled cross-sectional observations, however, it is clear that generational replacement is not the sole driving force of partisan dealignment, but that period effects should also be taken into account. While on an aggregate level rising levels of political sophistication have occurred simultaneously with decreasing partisanship, individual level analysis suggests clearly that the least sophisticated are most likely to feel alienated from the party system. We close with some very specific suggestion on how to address the democratic consequences of declining levels of partisanship.
