“…We shall also, in most cases, assume that information asymmetries prevent the government from lump-sum redistribution, meaning that the best achievable resource allocation is a second-best allocation. Although we focus on environmental externalities and their implications for tax policy, our study is thus closely connected to, and draws upon, a broad literature on optimal redistribution under consumption externalities, which includes environmental problems (e.g., Pirttilä and Tuomala, 1997;Cremer, Gahvari, and Ladoux, 1998;Cremer and Gahvari, 2001;Aronsson and Blomquist, 2003;Aronsson, Persson, and Sjögren, 2010), positional externalities (e.g., Oswald, 1983;Tuomala, 1990;Aronsson and Johansson-Stenman, 2008Aronsson and Mannberg, 2014), and altruism (e.g., Oswald, 1983).…”
