Countries have pledged to stabilize global warming at a 1.5 to 2°C increase. Either target requires reaching net zero emissions before the end of the century, which implies a major transformation of the economic system. This paper reviews the literature on how policymakers can design climate...

Anthropogenic climate change is one of the most pressing global issues today and finding means of mitigation is of utmost importance. To this end, we investigate whether carbon taxes on their own and coupled with revenue recycling schemes (symmetric or asymmetric carbon dividends) improve...

We study the variation of global and unilateral carbon price recommendations and their determinants. To this end, we provide survey evidence on carbon pricing from more than 400 experts across almost 40 countries. We quantify the extent of (dis-)agreement and reveal that a majority of experts...

Swiss climate policy consists of three regulatory instruments for greenhouse gas emissions reduction: A CO 2 levy, the Swiss Emissions Trading System (CH EHS), and an additional nonEHS" program for medium-sized plants that consists of command-and-control elements plus a sizeable abatement...

A global monopoly supplier country of necessary inputs for the provision of global public goods has an incentive to subsidize these exports. The strategic interdependence in the global public good context reverses the "large country" incentives to manipulate the terms-of-trade. It is optimal for...

World income grows fast without verifiable climate-change impacts on the economy. The growth spell can end if climate impacts turn real but this can take decades to learn. We develop a tractable stochastic climate-economy model with a hidden-state impact process to evaluate the contributions of...

This paper compares internationally-tradeable permits with a uniform carbon price, as seen through the lens of an individual country. To ensure a level playing field, these two approaches are initially calibrated to be welfare-equivalent for the country in a deterministic setting. While both...

We study optimal climate policy in a global economy where regions differ in wealth and climate vulnerability. Carbon emissions from production lead to output losses, and there is a technology for emissions absorption. We provide an aggregation result: the model with heterogeneity can be cast...

We analyse a principal-agent relationship in the context of international climate policy. Principals in two countries first decide whether to merge domestic emission permit markets to an international market, then delegate the domestic permit supply to an agent. We find that principals select...

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...
