Besley and Persson (2023) pioneer a political economy model of a green transition with changing preferences. Here we solve for the optimal policy intervention and find that the optimal tax on the polluting good starts high and is subsequently declining, to support the transition in preferences....

The allocation of free allowances for firms belonging to the carbon leakage list of the European Union Emissions Trading Scheme (EU ETS) was found to lead to substantial overcompensation, which is why some stakeholders recently have called for a phasing out of free allowances in the near term....

International carbon markets are frequently propagated as an efficient instrument for reducing CO2 emissions. We argue that such markets, despite their desirable efficiency properties, might not be in the best interest of governments who are guided by strategic considerations in negotiations. We...

I study the impact of subsidies for Plug-in hybrid vehicles (PHEV) on carbon emissions. I show that subsidizing innovations without considering consumer behavior can harm the environment. I provide descriptive evidence on charging instances of PHEV and combine it with a structural model of...

We evaluate German purchase subsidies for battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) using data on new vehicle registrations in Germany during 2015-2022. We account for confounding time trends and interacting EU-level CO2 standards using neighboring countries...

The success of climate policies depends crucially on the dynamics of public support. Using unique longitudinal data from three surveys conducted between 2019 and 2022, we study the variations of public support for carbon pricing in Germany. The period includes two relevant events: the...

We document majority support for policies entailing global redistribution and climate mitigation. Recent surveys on 40,680 respondents in 20 countries covering 72% of global carbon emissions show strong support for an effective and progressive way to combat climate change and poverty: a global...
