Climate-related risks have increased in recent decades, both in terms of the frequency of extreme weather events (physical risk) and implementation of climate-change mitigation policies (transition risk). This paper explores whether multinational firms react to such risks by altering their...

The problem of the commons is more important to our lives and thus more central to economics than a century ago when Katharine Coman led off the first issue of the American Economic Review. As the U.S. and other economies have grown, the carrying-capacity of the planet -- in regard to natural...

Because of the global commons nature of climate change, international cooperation among nations will likely be necessary for meaningful action at the global level. At the same time, it will inevitably be up to the actions of sovereign nations to put in place policies that bring about meaningful...

A new and important concept in global warming economics and policy is the social cost of carbon or SCC. This concept represents the economic cost caused by an additional ton of carbon-dioxide emissions or its equivalent. The present study describes the development of the concept as well as its...

This paper discusses the role that trade can potentially play in both negotiating and operating a post Kyoto/post 2012 global climate policy regime. As an addition to the bargaining set for a global climate negotiation, trade in principle widens the range of jointly beneficial potential outcomes...

Instead of efficiently pricing greenhouse gases, policy makers have favored measures that implicitly or explicitly subsidize low carbon fuels. We simulate a transportation-sector cap & trade program (CAT) and three policies currently in use: ethanol subsidies, a renewable fuel standard (RFS),...

There is great uncertainty about the impact of anthropogenic carbon on future economic wellbeing. We use DSICE, a DSGE extension of the DICE2007 model of William Nordhaus, which incorporates beliefs about the uncertain economic impact of possible climate tipping events and uses empirically...

Over the past two decades, the international community has struggled to deal constructively with the problem of mitigating climate change. This is considered by many to be the preeminent public policy challenge of our time, but actual policy responses have been relatively modest. This essay...

The United States Government recently concluded a year-long process to develop a range of values representing the monetized damages associated with an incremental increase in carbon dioxide (CO2) emissions, commonly referred to as the social cost of carbon (SCC). These values are currently used...
