Reform of support for fossil fuels is often identified as a priority for a country’s fiscal consolidation efforts and for climate action to align financial flows with low-carbon pathways. Its implementation, however, remains elusive for many countries as they face seemingly irreconcilable...

Understanding the distributional impacts of market-based climate policies is crucial to design economically efficient climate change mitigation policies that are socially acceptable and avoid adverse impacts on the poor. Empirical studies that examine the distributional impacts of carbon pricing...

We propose a global refunding scheme as a new international approach to addressing climate change. A global refunding system allows each country to set its carbon emission tax, while aggregate tax revenues are partially refunded to member countries in proportion to the relative emissions...

Viewing the Chinese economy as a speeding car, there are three types of development that could crash the car: (1) a hardware failure, which is the breakdown of an economic mechanism (analogous to the collapse of the chassis of the car), e.g. a banking crisis; (2) a software failure, which is a...

This paper, the first of two on global oil theft and fraud, discusses the prevalence, methods, and consequences of global oil theft, valued at US$133 billion per year and equivalent to 5-7 per cent of the global market for crude oil and petroleum fuels. However, the impact of oil theft is...

Although agriculture is an important source of greenhouse gas emissions, the sector remains out of scope for greenhouse gas (GHG) pricing policies. To align the future food system with the transition to net zero emissions, two key questions arise: To what extent can tax policies help achieving...

This paper examines how border carbon adjustments (BCAs) may address the unintended consequences of uncoordinated global climate action, focusing on the economic implications for Canada. We investigate these implications under different BCA design features and by considering a coalition of...
