It is widely believed that an environmental tax (price regulation) and cap-and-trade (quantity regulation) are equally efficient in controlling pollution when there is no uncertainty. We show that this is not the case if some consumers (firms, local governments) are morally concerned about...

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....

We study the interaction of climate policies and investments into fossil and renewable energy generation capacity if policies are set by democratically elected governments and can lead to stranded assets. We develop an overlapping generations model, where elections determine carbon taxation and...

The green paradox conveys the idea that climate policies may have unintended side effects when taking into account the reaction of fossil fuel suppliers. In particular, carbon taxes that will be implemented in the future induce resource owners to extract more rapidly which increases present...

This paper analyzes the impact of declining extraction costs of shale oil producers on the choice of the policy instrument of a climate coalition in the presence of a monopolistic oil supplier such as OPEC. Shale oil producers' extraction costs represent an upper bound for the oil price OPEC can...

Technology policy is the most widespread form of climate policy and is often preferred over seemingly efficient carbon pricing. We propose a new explanation for this observation: gains that predominantly accrue to households with large capital assets and that influence majority decisions in...

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...

By using estimates from an Almost Ideal Demand System (AIDS), we investigate how the German energy tax on car fuels changes the private households-CO2 emissions, living standards, and post-tax income distribution. Our results show that the tax implies a trade-off between the aim to reduce...
