Replication Data for: Policy framing, design and feedback can increase public support to costly food waste regulation

Data and scripts replicate the analysis for: Policy framing, design and feedback can increase public support to costly food waste regulation, forthcoming in Nature Food. Abstract: Stricter regulation for food waste reduction is widely presumed to increase food prices, which could render its implementation politically unfeasible. Here, we checked empirically whether specific policy framing, design and feedbacks could help ensure public support despite potential food price increases. We used survey experiments with 3,329 citizens from a high-income country, Switzerland. A combined framing and conjoint experiment showed that messages emphasizing national or international social norms in favor of reducing food waste (policy framing) can increase public support for more ambitious reduction targets. Also, most citizens supported food waste regulation even if this leads to substantial increases in food prices but only if such policies set stringent reduction targets and are transparently monitored (policy design). Finally, a vignette experiment revealed that voluntary industry initiatives did not crowd out individuals’ support for stricter governmental regulation, but potentially crowd-in support if industry initiatives are unambitious (policy feedback).
