Research about the circular economy is dominated by engineers, architects, and social scientists in fields other than economics. The concepts they study can be useful in economic models of policies - to reduce virgin materials extraction, to encourage green design, and to make better use of...

Open access, competitive exploitation can be incredibly damaging to valuable resources and the human populations that depend upon them. Even though wealth, resource rents and stocks are at stake, open access often seems to be ineffectively addressed across time and space. Institutions vary....

This paper asserts that reporting of the ratio of welfare gains to tax revenue should be standard protocol in economic analyses of externality correcting taxes. That this comparison might matter is somewhat of a "blind spot" in most economic analyses, for it plays virtually no role when...

We summarize the economics of recycling municipal solid waste. OECD data suggest that aggregate recycling rates in member countries have plateaued in recent decades. United States recycling rates for some materials remain low, even after decades of learning and participation. Major new policies...

We explore the economic effects of biodiversity loss by developing an ecologically-founded model that captures how different species interact to deliver the ecosystem services that complement other factors of economic production. Aggregate ecosystem services are produced by combining several...

A popular approach for estimating climate change impacts on agriculture is to rely on supply-side reduced-form regressions. These methods, which include the Ricardian approach, focus on how farmers and agricultural land market react to changes in climatic conditions, under the implicit...

China's recently launched CO2 emissions trading system, already the world's largest, aims to contribute importantly toward global reductions in greenhouse gas emissions. The system, a tradable performance standard (TPS), differs importantly from cap and trade (C&T), the principal emissions...

Economists often regard broad-based carbon pricing (whether in the form of a carbon tax or cap and trade) as the most efficient policy to reduce carbon dioxide emissions. Relative to a narrower policy that exempts some emissions sources, a broader policy is often favored because it can exploit...

We analyze the impact on crime of 3.7 million refugees who entered and stayed in Turkey as a result of the civil war in Syria. Using a novel administrative data source on the flow of offense records to prosecutors' offices in 81 provinces of the country each year, and utilizing the staggered...

How has the internet affected search and hiring, and what are the implications for aggregate unemployment? Answering these questions empirically has proven difficult due to selection in internet use and difficulty in measuring the search activities of both sides of the labor market. This paper...
