Party Positioning Space: A Comprehensive Framework for Understanding Multidimensional Policy-Making Dynamics
Dissertation abstract
Existing research in political science – specifically party politics – overwhelmingly analyze
political parties from a voter-centric perspective. As a result, parties are often portrayed as
unitary actors with a few salient policy dimensions that they campaign on for each election. In
reality, however, parties constantly navigate both inter-party and intra-party conflicts while
spreading their interests across a far broader range of policy dimensions. Therefore, to better
understand how parties negotiate within and between themselves to reach agreements on key
policy issues, I argue for a shift from a voter-centric to a party-centric perspective. This shift
requires a comprehensive theoretical and methodological framework which considers party
positions as being multidimensional, stochastic, and fluid over time.
Existing frameworks either do not support party-centric view or lack a proper method for
scaling stochastic and multidimensional party positions. This cumulative dissertation addresses
such a gap by introducing the Party Positioning Framework, developed and implemented
through three independent research articles. The first paper presents ContextScale, a sentimentbased approach to scaling multidimensional party positions at the sequence level. Unlike
existing scaling methods, ContextScale can distinguish between conflictual and non-conflictual
situations, generating a multidimensional positioning space across all policy topics for each
party. The second paper improves ContextScale’s cross-domain classification performances by
adopting a domain adaptation pipeline which significantly mitigates performance degredation
when transferring across political domains without additional fine-tuning. Finally, the third
paper applies ContextScale to the case of Germany, highlighting the complex strategies parties
employ in their position-taking across stages of the policy making process (from manifestos to
parliamentary debates). Empirical findings from the second and third papers demonstrate that
adopting a party-centric perspective offers valuable insights into party politics and party
competition.
