Replication Data for: Partisan voters in party systems with ephemeral parties: Evidence from South Korea

This dataset accompanies the article "Partisan voters in party systems with ephemeral parties: Evidence from South Korea" and contains cleaned respondent-level survey data and conjoint attribute evaluations from a nationally representative online survey conducted in South Korea. The study fielded a paired profile conjoint experiment embedded within a broader political attitudes survey. Respondents evaluated hypothetical presidential candidates whose characteristics and policy stances were randomly varied. In addition to conjoint evaluations, the dataset includes standard demographic, attitudinal, and political behavior measures. Two datasets are included: - `final_df_direct.csv`: Respondent-level data with demographics, political preferences, policy attitudes, and manipulation check. - `final_df_conjoint.csv`: Merged data including conjoint profile evaluations linked to respondent characteristics. Each dataset is accompanied by a structured data dictionary. There is also a README document.
