Over the last two decades, U.S. households have received $47 billion in tax credits for buying heat pumps, solar panels, electric vehicles, and other "clean energy" technologies. Using information from tax returns, we show that these tax credits have gone predominantly to higher-income...

This paper examines capital income taxation in Ghana. We calculate effective marginal tax rates (EMTR) and effective average tax rates (EATR) using an extended Devereux-Griffith methodology to accommodate for tax incentives – an exercise that has not been done so far for Ghana. We find that...

While Tanzania's greenhouse gas emission levels still seem low by international comparison, the country is rapidly carbonizing, and most households still rely on kerosene, charcoal, and firewood for cooking and lighting. Carbon pricing can be an effective tool to discourage the creation of high...

L’activité humaine a transformé la planète à un rythme et à une échelle sans précédent dans l’histoire, causant des dommages irréversibles aux communautés et aux écosystèmes. Les pays ont concentré leurs capacités sur la croissance économique, avec peu d’attention aux...

We analyze a fundamental dilemma and time-inconsistency problem facing a climate coalition producing natural gas. In the short term, it is tempting to export more to outcompete coal. When this policy is anticipated, however, investments in renewables fall and emissions ultimately increase. When...

The goal of this work is to improve the spatial representation of the Regional Dynamic Integrated model of Climate and the Economy (RICE), in its '99 version, focusing on the Mediterranean countries, while also updating the calibration to the base year 2015. We evaluate the impact of climate...

Novel Carbon Dioxide Removal (CDR) technologies have seen a first wave of deployment, driven by investments through voluntary carbon markets and by specific support policies. To sustain the momentum, a credible long-term policy path is urgently needed to lead removal technologies through the...

Es besteht mittlerweile ein Konsens, dass die CO2 -Abscheidung und Speicherung (CSS) eine Rolle bei der Erreichung von Klimaneutralität spielen sollte. Vor dem Hintergrund der nationalen und internationalen Entwicklung stellt sich die Frage, welche Emissionen überhaupt über CCS gemindert...

We formalize and estimate the dynamic marginal efficiency cost of redistribution (MECR) in the spirit of Okun’s “leaky bucket” to compare the MECR of an income-contingent childcare subsidy program and of the income-contingent tax and transfer schedule. We set up a dynamic structural model...

We analyze how conventional emissions trading schemes (ETS) can be modified by introducing ”clean-up certificates” to allow for a phase of net-negative emissions. Clean-up certificates bundle the permission to emit CO2 with the obligation for its removal. We show that demand for such...
