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 report numerical simulation results using a multiyear global multi country modeling framework which we use to assess the impacts of alternative emissions cuts which will likely come under consideration for the process to follow the December 2009 UNFCCC negotiation in Copenhagen. The...

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...

Most regulations designed to reduce environmental externalities impose costs on individuals and firms. An active body of research has explored how these costs are disproportionately born by different sectors of the economy and/or across different groups of individuals. However, much less is...

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...

Wildfire activity has increased in the US and is projected to accelerate under future climate change. However, our understanding of the impacts of climate change on wildfire smoke and health remains highly uncertain. We quantify the past and future mortality burden in the US due to wildfire...

This paper explores the trade-off between incentive effects and administrative costs associated with the implementation of various environmental tax instruments, with special reference to carbon taxes. In a simple model, we show under what conditions it is optimal to use input rather than...

The extent of social expenditures in the U.S. and the Nordic Countries is compared in the early 1900s and again in the early 2000s. The common view that America spends much less on social welfare than the Nordic countries does not survive closer inspection when we consider the differences in the...

In the late 1980s and early 1990s, concern over dioxin in both paper products and wastewater led to the development of techniques that reduced the use of chlorine in the pulp industry. Both regulatory and consumer pressure motivated this change. We use patent data to examine the evolution of two...

This paper argues that it is essential to explicitly consider how the government spends tax revenues when assessing the effects of tax rates on aggregate hours of market work. Different forms of government spending imply different elasticities of hours of work with regard to tax rates. I...
