Abstract Reducing the emissions of greenhouse gases may be almost impossible without a green transition—a substantial transformation of consumption and production patterns. To study such transitions, we propose a dynamic model, which differs from the common approach in economics in two ways. First, consumption patterns reflect not just changing prices and taxes, but changing values. Transitions of values and technologies create a dynamic complementarity that can help or hinder a green transition. Second, and unlike fictitious social planners, policy makers in democratic societies cannot commit to future policy paths, as they are subject to regular elections. We show that market failures and government failures can interact to prevent a welfare-increasing green transition from materializing or make an ongoing green transition too slow.

Abstract This paper studies individual and social motives in tax evasion. We build a simple dynamic model that incorporates these motives and their interaction. The social motives underpin the role of norms and are the source of the dynamics that we study. Our empirical analysis exploits the adoption in 1990 of a poll tax to fund local government in the United Kingdom, which led to widespread evasion. The evidence is consistent with the model's main predictions on the dynamics of evasion.

Abstract We study the politicians and voters of the Sweden Democrats, a major populist radical-right party. Based on detailed administrative data, we present the first comprehensive account of which politicians are selected into such a party. Surveys show that politicians and voters of the Sweden Democrats share strong anti-establishment and anti-immigration attitudes that drastically set them apart from Sweden’s other parties. Searching for individual traits that link naturally to these attitudes, we classify the universe of Swedish politicians and voters by social and economic marginalization and exposure to immigration. Politicians from the Sweden Democrats over-represent marginalized groups without strong attachments to the labour market or to traditional nuclear families, which instead are under-represented among politicians in all other parties. Among voters, the Sweden Democrats have higher electoral support in precincts with higher shares of the same marginalized groups. We see the mobilization of the marginalized as an important driver of the party’s success. Finally, we uncover that Sweden-Democrat politicians score lower on a number of valence traits than other-party politicians. In sum, the rise of the Sweden Democrats raised political representation for marginalized groups, but this came at a valence cost.
