As an empirical example of this externality, we analyze the innovation induced by the obesity epidemic. Obesity is associated with an increase in the incidence of many diseases. The induced innovation hypothesis is that an increase in the incidence of a disease will increase technological...

A unilateral carbon tax trades off the distortionary costs of taxation and the future gains from slowing down global warming. Because the cost is local and immediate, whereas the benefit is global and delayed, this tradeoff tends to be unfavorable to unilateral carbon taxes. We show that this...

We study the economic effects of the interaction of nature loss and climate change in a model that incorporates important aspects of both processes. We capture the distinct ways in which they affect economic activity--with nature constituting a key factor of production and climate change...

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...

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...

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...

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....

We introduce dynamic incentive contracts into a model of unemployment dynamics and present three results. First, wage cyclicality from incentives does not dampen unemployment dynamics: the response of unemployment to shocks is first-order equivalent in an economy with flexible incentive pay and...

The globalization hazard hypothesis maintains that the current account reversals and asset price collapses observed during 'Sudden Stops' are caused by global capital market frictions. A policy implication of this view is that Sudden Stops can be prevented by offering global investors price...
