This paper develops and tests a model in which 1) purpose-driven firms emerge as an optimal organizational form even for profit-maximizing entrepreneurs; and 2) CSR arises endogenously as a response to imperfect regulatory oversight. Purpose-driven organizations allow entrepreneurs to create...

We discuss global climate mitigation that builds on existing unilateral measures to cut emissions. We document and discuss the rationale for such unilateral measures argue that such measures have the potential to generate positive spillover effects both within and across countries. In a simple...

An estimate of the social cost of carbon (SCC) is key to climate policy. But how should we estimate the SCC? A common approach is to use an integrated assessment model (IAM) to simulate time paths for the atmospheric CO2 concentration, its impact on global mean temperature, and the resulting...

Though air-quality alert systems (AQAS) cover more than 1.7 billion people worldwide, there has been little welfare analysis of these systems. This paper presents a theoretical framework for deriving lower bounds on the net benefits of an AQAS and applies it to a South Korean system currently...

Household carbon dioxide emissions have been an increasing function of income and distance from the city. Richer suburbanites drive more and consume more electricity and natural gas at home. In recent years, richer people in California have been more likely to buy electric vehicles and to...

Over the past decade, concern over potential global warming has focused attention on the emission of greenhouse gases into the atmosphere, and there is an active debate concerning the desirability of reducing emissions. At the heart of this debate is the future path of both greenhouse gas...

We compare the spatial distribution of emissions from Southern California's pollution-trading program with that of a counterfactual command-and-control policy. We develop a normatively significant metric with which to rank the various distributions in a manner consistent with an explicit...

A sizeable number of papers beginning with Roberts and Spence (1976) have studied the use of price floors and ceilings (or "collars") to manage prices in tradable permit markets. In contrast, economists have only recently begun examining polices to manage quantities under a pollution tax....
