Location and Political Choice in Post-Unification Berlin: Explaining the PDS (Party of Democratic Socialism) Vote, 1999 and 2001

A paper examining the factors contributing to the growing electoral support for the PDS (Party of Democratic Socialism) in post-unification elections in the former German Democratic Republic (East Germany) uses detailed data for Berlin's electoral districts to elucidate the micro-geography of the East-West divide in the PDS vote. Using two methods of ecological inference, King's and entropy maximization, the authors show that the explanation of the PDS support in Berlin elections in 1999 and 2001 can be attributed to the "Mauer in den Köpfen" (wall in people's heads) that is coincident with the division of the city along the former Berlin Wall. This geographic division far exceeds any socio-demographic explanation of the PDS vote. Journal of Economic Literature, Classification Numbers: H10, O10, R10. 9 figures, 4 tables, 98 references.
