This paper examines biases in policy responsiveness in post-industrial Europe based on the political parties in government. Using a time-series cross-country analysis of 20 European countries from 1985 to 2018, with survey data from the International Social Survey Programme (ISSP), the study explores how public opinion influences changes in policies in both economic (social spending) and cultural (trade, immigration, and environmental) dimensions. In the economic dimension, government responsiveness is shaped by a two-block structure, with left-wing governments responding to the preferences of lower-income groups, and right-wing governments aligning with higher-income groups. However, mainstream parties need the pressure of challenger parties in government to fully respond to the preferences of their constituents. In the cultural dimension, responsiveness follows a tripartite structure: (1) Left, (2) Centre-Right, and (3) Centre-Right with Radical Right governments. The Centre-Right alone tends to favour higher-income groups, while the inclusion of the Radical Right leads to policies that better reflect the preferences of lower-income groups, particularly on issues like immigration. The paper concludes that right-wing governments, especially those including Radical Right parties, respond to their constituencies on both dimensions, while left-wing governments respond only on economic issues, limiting their electoral success. This research highlights the significant role of partisan responsiveness in shaping policy outcomes in Europe.
