Renewable Portfolio Standards (RPSs) are a key policy measure used by U.S. states to increase their production of renewable electricity. Economic theory shows that RPSs are not first-best policy measures for mitigating greenhouse gas emissions or solving other environmental problems....

Corporate greenwash has accelerated in recent years, bringing in its wake growing skepticism about corporate green claims. Although a theory of the drivers and deterrents of greenwash has begun to emerge, it is static in nature and does not incorporate the full range of ways in which firms can...

An increasingly popular instrument for solving environmental problems is the "public voluntary agreement (VA)", in which government offers technical assistance and positive publicity to firms that reach certain environmental goals. Prior papers treat such agreements as a superior, low-cost...

We extend the economic theory of regulation to allow for strategic self-regulation that preempts political action. When political "entry" is costly for consumers, firms can deter it through voluntary restraints. Unlike standard entry models, deterrence is achieved by overinvesting to raise the...

The traditionally large and sunk nature of utility investments gives rise to the possibility, if not the likelihood, of opportunistic behavior on the part of either regulators or regulated firms. In this paper, we develop a theoretical model to provide insights into this possibility, then employ...

In many markets, governments set minimum quality standards while some sellers choose to compete on the basis of quality by exceeding them. We analyze this phenomenon using a model of vertical product differentiation, interpreting quality as an "environmental friendliness" characteristic fully...

We survey the growing theoretical literature on the motives for and welfare effects of corporate greening. We show how both market and political forces are making environmental CSR profitable, and we also discuss morally-motivated or altruistic CSR. Welfare effects of CSR are subtle and...

Jarrell (1978) found that electricity prices rose in states that adopted state regulation before 1917, suggesting that regulators were "captured" by the interests of the regulated electric utilities. An alternative explanation is that state regulation more credibly protected specialized utility...

Behind closed doors, many large companies quietly use their political clout to influence public policy on social and environmental issues - often in a negative direction. This book seeks to create a new norm for responsible political behaviour by corporations. It brings together leading scholars...
