This work presents a modified version of the integrated economic-climate model RICECH₄. The aim of the work was to expand the basic RICE model by explicitly accounting for methane (CH₄) emissions along with traditional carbon dioxide (CO₂) emissions, as well as the subsequent analysis of...

A central challenge in the global transition to cleaner energy is how governments can design policies that deliver large social benefits while facing trade-offs in energy security, fiscal costs, and household adoption frictions. We study this question in urban Nepal, where cooking is dominated...

Despite widespread concern about climate change, voluntary mitigation efforts often fail to maximize impact. In two online experiments (n = 1, 500), we elicit willingness to mitigate (WTM) by allowing subjects to delete actual CO2 allowances and examine how they allocate the WTM between their...

Climate change impacts are intensifying worldwide, with the harshest consequences borne by vulnerable developing countries that face high exposure and limited capacity to adapt. Although international agreements commit wealthy donor countries to provide adaptation finance, actual transfers...

The most of Sub-Saharan African (SSA) countries have been affected by climate change and food insecurity problems due to the reduction of production and productivity of cereal crops in the continent. The purpose of this research was to examine the short-run and long-run effects of climate change...

Weather variability disrupts food grain production and agricultural sustainability. While existing literature highlights the stationary relationship between weather variables and agricultural outcomes, it often overlooks their bearing on land use changes. This study investigates the dynamic...

We propose a theory of public appraisal and employ it to explain divergent public opinion on similar economic policy instruments. In a survey-based policy design experiment with 13,665 respondents from seven European countries, we study how policy perceptions and support rates differ across...

Although economists widely advocate carbon pricing as an effective solution to reduce carbon emissions, this mechanism has had so far limited effects. This paper proposes a new type of tax to help finance (and accelerate) the green transition. A carbon wealth tax (CWT) is proposed to be levied...

This paper surveys beliefs about the climate impact of green investing among academic experts and retail investors. Using the views of academic experts as a benchmark, we show that retail investors have overly optimistic climate impact beliefs. While most academic experts do not believe that a...

How should taxes on externality-generating activities be adjusted if they are regressive? In our model, the government raises revenue using distortionary income and commodity taxes. If more or less productive people have identical tastes for externality-generating consumption, the government...

Circularity has advanced to a key strategy for transforming our society: closing the loop is expected to enable economic profits independent of resource consumption and its associated environmental impacts (Blomsma & Brennan, 2017; Bocken et al., 2021; Circle economy, 2023; Ellen MacArthur Foundation, 2019;...

We empirically examine the impact of carbon pricing on key macroeconomic variables and inclusive development with a newly compiled panel dataset covering 48 countries from 1989 to 2024. Using the local-projection difference-in-differences approach, we find that the introduction of carbon pricing...
