Moving beyond the combination of adoption subsidies, standards, and (albeit limited) attempts at carbon pricing that largely characterized U.S. climate policy over the last decade, recent climate-related legislation has transformed not only the scale of U.S. climate activities but also the...

We investigate the short- and long-term effects of a natural gas boom in an economy where energy can be produced with coal, natural gas, or clean sources and the direction of technology is endogenous. In the short run, a natural gas boom reduces carbon emissions by inducing substitution away...

This paper provides a primer on the economics of environmental innovation. Our intention is not to write a pure review paper, but to also provide an up-to-date textbook treatment on the issue. Thus, we start by defining the marginal costs of both emissions and of emissions abatement. We then...

Shared socioeconomic pathways (SSPs) are perhaps the most influential economic policy analyses today. My paper evaluates their development, natural associations, logical consequences, and economic identification. All five SSP baseline scenarios are predicting scenarios that historical...

This paper studies the economic impacts of carbon pricing. Exploiting institutional features of the European carbon market and high-frequency data, I document that a tighter carbon pricing regime leads to higher energy prices, lower emissions and more green innovation. This comes at the cost of...

The costs of low-carbon energy fell dramatically over the past decade, leading to rapid growth in its deployment. However, many challenges remain to deploy low-carbon energy at a scale necessary to meet net zero carbon emission targets. If net zero goals are to be met, developing complementary...

The phasedown of coal for electricity generation is considered vital to meeting global climate targets. Many countries have pledged to stop using coal, with some as early as 2030. While the United States has no target currently in place, several states do. In this paper, we examine the...

Many US states have set ambitious renewable portfolio standards (RPS) that require utilities to switch from fossil fuels toward renewables. RPS increases the renewables capacity, bond issuance, maturity, and yield spreads of investor-owned utilities compared to municipal producers that are...

Advocates in several countries have promoted a "green recovery" from the pandemic, with an emphasis on measures to address climate objectives. We evaluate proposals for the United States and find that as stated, ambitious plans to further cut emissions from transportation and electricity will...

This paper investigates the impact of carbon pricing on the economy, with a focus on European carbon taxes and the carbon market. Our analysis reveals three key findings. First, while both policies have successfully reduced emissions, the economic costs of the European carbon market are larger...
