The unprecedented deterioration of our global environment has increased the necessity of relying upon Green Economic policies as critical and effective environmental management tools. The current situation has stimulated extensive research and debate among global interest groups. This has...

We investigate the possibility of using public firms to regulate polluting emissions in a Cournot oligopoly where production takes place at constant returns to scale and entails a negative environmental externality. We model the problem as a differential game and investigate (i) the Cournot-Nash...

Garrett Hardin's “The Tragedy of the Commons” (Hardin, 1968) is widely influential but fundamentally incorrect. Hardin characterizes the commons problem as arising from the exercise of free will in a world with limited carrying capacity. Hardin's solutions to this problem emphasize coercive...

This paper provides stark evidence of hysteresis -- the failure of an effect to reverse itself as its underlying cause is reversed -- in energy demand. We estimate that half of the 23%-reduction in residential electricity use caused by a 9-month-long policy that was imposed on millions of...

Humans are fundamentally social. Social activities require coordination, which may yield multiple equilibria in the form of stable, self-reinforcing patterns of herd behavior. Since environmental impacts can differ substantially between alternative equilibria, such self-reinforcing behaviors...

The BP Deepwater Horizon oil spill of 2010 has focused considerable attention on the potential liability and the operating conduct of big oil companies. This paper shows that, limiting the ability of a company to insure and diversify its risks, creates incentives to internalize the welfare...

This paper summarizes the findings of two papers that examine the effect of environmental regulation on the production decisions and profits of polluting and green firms. Using a game-theoretic framework, we find conditions under which the green firm favors regulation (a standard finding), but...

If one nation damages another, what are its obligations? This question can be approached and understood in diverse ways, but it is concretized in debates over the social cost of carbon, which is sometimes described as the linchpin of national climate policy. The social cost of carbon, meant to...
