The paper assesses the marginal welfare and equity impacts of three transport instruments in the presence of three transport externalities: congestion, air pollution and accidents. It considers a second-best economy in which the government has to use distortionary taxes for revenue-raising and...

In a first for South Africa, we draw on literature on infrastructure productivity to model dynamic economywide employment impacts of infrastructure investment funded with different fiscal tools. According to the South African investment plan, the policy will affect the stock of infrastructure as...

Many personally risky decisions, such as innovation and entrepreneurship, have the potential to increase overall welfare by creating positive externalities for society. Rewarding such prosocial risk-taking may be an important strategy in addressing societal challenges like, for example, the...

This paper revisits the path by which Coase developed the result now known as the Coase theorem, including the famous meeting at the home of Aaron Director during which Coase 'converted' a group of Chicago economists to his way of thinking. Drawing on published and archival sources, we discuss...

Recycling waste from used goods can substitute for scarce raw materials and reduce resource dependence. This paper presents a model of waste collection, recycling and final goods production using raw and recycled materials. Non-recycled waste must be safely stored by landfill to avoid...

While wind power is considered key in the transition towards net zero, there are concerns about adverse health impacts on nearby residents. Based on precise geographical coordinates, we link a representative longitudinal household panel to all wind turbines in Germany and exploit their staggered...

Carbon leakage is one of the major issues facing policymakers today when designing environmental regulation. While the empirical and trade literature on carbon leakage is rich, much less is known about the implications of carbon leakage risk on optimal regulatory policies under asymmetric...

This paper discusses the externalities and market failures in cryptocurrency markets. In particular, I highlight the significant environmental externalities created by Proof-of-Work (PoW) cryptocurrencies, the most prominent of which is Bitcoin. The main goals of this paper are to quantify these...

While wind power is considered key in the transition towards net zero, there are concerns about adverse health impacts on nearby residents. Based on precise geographical coordinates, we link a representative longitudinal household panel to all wind turbines in Germany and exploit their staggered...

Many consumers care about climate change and other externalities associated with their purchases. We analyze the behavior and market effects of such "socially responsible consumers" in three parts. First, we develop a flexible theoretical framework to study competitive equilibria with rational...
