First, they must deal with an intra-generational conflict that emerges from the allocation of costs of climate change mitigation among different actors of the current generation. Second, they face an inter-generational conflict that stems from the higher costs for long-term mitigation measures, particularly helping future generations, compared to the short-term actions aimed at adapting to the immediate effects of climate change, benefiting mostly the current generation. We devise a novel game to study this multi-level conflict and investigate individuals\u2019 behavior in a lab experiment. We find that, although individuals reach sufficient cooperation levels to avoid adverse consequences for their own generation, they contribute more to cheaper short-term than to costlier long-term measures, to the detriment of future generations. Simple \u201cnudge\u201d interventions, however, may alter this pattern considerably. We find that changing the default contribution level to the inter-generational welfare optimum increases long-term contributions. Moreover, providing individuals with the possibility to commit themselves to inter-generational solidarity leads to an even stronger increase in long-term contributions. Nevertheless, the results also suggest that nudges alone may not be enough to induce inter-generationally optimal contributions.<\/jats:p>","DOI":"10.3390\/g11040042","type":"journal-article","created":{"date-parts":[[2020,10,17]],"date-time":"2020-10-17T07:23:22Z","timestamp":1602919402000},"page":"42","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Nudging Climate Change Mitigation: A Laboratory Experiment with Inter-Generational Public Goods"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6806-0374","authenticated-orcid":false,"given":"Robert","family":"B\u00f6hm","sequence":"first","affiliation":[{"name":"Department of Psychology, Department of Economics, and Copenhagen Center for Social Data Science (SODAS), University of Copenhagen, \u00d8ster Farimagsgade 2a, 1353 Copenhagen K, Denmark"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7971-7319","authenticated-orcid":false,"given":"\u00d6zg\u00fcr","family":"G\u00fcrerk","sequence":"additional","affiliation":[{"name":"Faculty of Law, Social Sciences, &amp; Economics, University of Erfurt, Nordh\u00e4user Str. 63, 99089 Erfurt, Germany"}]},{"given":"Thomas","family":"Lauer","sequence":"additional","affiliation":[{"name":"Erfurt Laboratory for Empirical Research, University of Erfurt, Nordh\u00e4user Str. 63, 99089 Erfurt, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,9]]},"reference":[{"key":"ref_1","unstructured":"Burke, E.
