Jurisdictions adopt heterogeneous climate policies that vary in terms of both ambition and policy approach, with some jurisdictions pricing carbon and others subsidizing clean production. We distinguish two types of policy spillovers associated with diverse policy approaches to climate change....

The socio-political processes that influence the acceptance of climate policies play a crucial role in shaping mitigation strategies. In this paper, we explore the interplay between social and political dynamics and their impact on climate policy support. Using a simplified model of the...

The urgency of responding to climate change and the need for stronger actions to mitigate GHG emissions have been at the forefront of global efforts. Multilateral cooperation centered on the Conference of the Par-ties of the United Nations Framework Convention on Climate Change (UNFCCC) and the...

Under the 2022 Inflation Reduction Act, the United States has for the first time implemented a methane emissions fee as a backstop to new methane regulations in the oil and gas sectors. The European Union is also implementing methane regulations on fossil energy. Methane is a short-lived but...

Weitzman, M.L. (2014. Can negotiating a uniform carbon price help to internalize the global warming externality? J. Assoc. Environ. Resour. Econ. 1: 29-49) proposed that focusing international climate negotiations on a uniform common commitment (such as a uniform carbon price) is more effective...

Several empirical studies document the relevance of firm heterogeneity to assess the effect of trade and environmental policy. This paper develops a multi-country and -sector general equilibrium trade model with heterogeneous firms and analyzes the effect of domestic carbon pricing as well as...
