In May 2018, Scotland introduced a minimum unit price on alcohol. We examine the impact of this policy on traffic fatalities and drunk driving accidents. Using administrative data on the universe of vehicle collisions in Britain and a range of quasi-experimental modeling approaches, we do not...

A formula is derived for the social cost of carbon (SCC) that takes account of intragenerational income inequality and its evolution with economic growth. The social discount rate (SDR) should be adjusted to account for intragenerational and intergenerational inequality aversion and for risk...

We consider if a road is self-financing under flat or step tolling and optimized capacity while incorporating preference heterogeneity, bottleneck congestion and linear capacity cost. Previous work has shown that a sufficient condition for the toll revenue to equal the capacity cost is that the...

This paper studies optimal second-best corrective regulation, when some agents/activities cannot be perfectly regulated. We show that policy elasticities and Pigouvian wedges are sufficient statistics to characterize the marginal welfare impact of regulatory policies in a large class of...

Gradient capital allocation, also known as Euler allocation, is a technique used to redistribute diversified capital requirements among different segments of a portfolio. The method is commonly employed to identify dominant risks, assessing the risk-adjusted profitability of segments, and...

Recycling of raw material can make a significant contribution to achieving climate neutrality by 2050. Carbon pricing can encourage material recycling by making it more competitive with waste incineration and primary material production. However, accounting for the interactions among different...

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...

Due to taxes and subsidies, gasoline prices vary dramatically across countries. Externalities cannot fully account for this. We develop a simple political-economic model that shows that group interests, resulting from the composition of a country's car fleet, help to explain differences in...

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...
