Dataset for the paper The comparative politics of solidarity: political party discourse across three welfare state regimes

Party political conflict plays an essential role in shaping welfare policies, while they are simultaneously also shaped by these policies. As political parties grapple with the wicked challenges of our times, new forms of solidarity and solidarity conflicts arise across welfare regimes. Despite their significance, these dynamics have not received much recent attention. Our paper aims to fill this gap. Through content analysis of party manifestoes, we compare the solidarity frames of political parties within and between three distinct welfare regimes – Flanders (Belgium), Sweden, and the United States. Our results confirm our expectations drawn from political feedback literature: while party ideology influences parties’ solidarity frame preferences and solidarity conflicts between parties, these preferences and conflicts are also influenced by a welfare regime’s societal solidarity norms. Our paper highlights the value of analyzing solidarity frames and political solidarity conflicts within welfare-state regimes to better understand welfare politics and policies.
