  1. Public Support for Climate Policies: Costs, Redistribution, and Ideological Divides Publicat

    Resum

    Securing public support for climate policies remains a major challenge. Citizens’ perceptions of the costs, benefits, and distributive consequences of these policies are key factors shaping their attitudes, yet how these dimensions interact remains insufficiently understood. This question is addressed through two experimental studies in Spain. Study 1 embeds a vignette experiment in two surveys to analyse how exposure to the costs or benefits of ten climate policies affects support. Cost framing significantly reduces support, whereas benefit framing has only a modest positive effect. Study 2 implements a conjoint experiment to examine how costs, benefits, and redistributive implications jointly influence preferences for climate policy packages. Results confirm previous evidence regarding costs and benefits and highlight the central role of redistribution: citizens strongly favour policies improving the situation of the poorest, while ideological divides reveal that left-wing voters are more supportive and sensitive to redistributive cues.

    Resum

    Recruiting participants to probability-based online panels is increasingly difficult. Drawing on social exchange, leverage-salience, and prospect theory, four large-scale field experiments in Finland, Sweden, and Spain (2022–2023) were designed to assess whether targeted appeals and framing strategies could improve cooperation. Contrary to expectations, neither targeting nor framing consistently improved recruitment rates, reduced nonresponse bias, or lowered administration costs. In one case, territorial targeting with a loss frame in Catalonia produced higher recruitment but at the expense of representativeness. These findings establish boundary conditions for established theories. Whereas targeting and framing can matter in survey invitations, they have limited impact on panel recruitment, where leverage is low and message salience is weak. Our results contribute to survey methodology by showing that small textual interventions are insufficient to make a difference for panel recruitment and point toward the need for stronger, more salient, and context-sensitive designs to improve online probability panel recruitment.

    Resum

    This study examines the age gap in political interest, exploring the possibility that the observed differences between age groups arise from the broad, unspecified nature of survey questions that refer generically to "politics." A randomized survey experiment asked about political interest in general (control) or prompted individuals with youth-centric issues in Spain (housing, labour precarity), traditional topics (elections, parties), and contemporary issues (climate change, gender equality). Results show youth-centric topics significantly reduce the age gap, while traditional issues widen it. Contemporary issues had little effect. These findings suggest that standard survey questions used to measure political interest may inadvertently overstate the extent of youth disengagement. While not the sole explanation, this measurement effect substantially contributes to the age gap and highlights the need to align survey instruments—and broader political discourse—with issues more salient to younger audiences.

  • Improving Representativeness in Probability-Based Panel Recruitment through Adaptive Survey Design: Evidence from the Catalan Citizen Panel Document de treball
    Ardiaca, J., Muñoz, J., Tormos, R.
    Resum

    This paper evaluates the application of Adaptive Survey Design (ASD) to improve representativeness during the recruitment phase of the Catalan Citizen Panel, a probability-based push-to-web+paper panel in Catalonia. Using randomized experiments and predictive modeling on over 120,000 sampled individuals across six waves, we estimate treatment-specific response propensities and allocate recruitment efforts accordingly. Our optimization framework aims to maximize representativeness, under realistic budget constraints. Simulations suggest that ASD-based treatment assignment improves representativity compared to random or uniform allocation, with minimal impact on overall response rates. The findings offer a practical path for implementing data-driven recruitment strategies in public opinion research.
