| We investigate the relationships between water quality and socioeconomic factors in California at the county level for the years 1993 to 2006 using 24 water quality indicators coming from seven different types of water bodies. We estimate these relationships using three classes of models: the traditional per capita income-pollution level - Environmental Kuznets Curve (EKC) - specifications, a more inclusive model containing main socioeconomic variables such as agricultural intensity, land use, ethnic composition, population density and educational attainment, and a model that includes the socioeconomic variables while accounting for spatial correlations too. For most water quality indicators, we do not find support for EKC specifications. For pollutants... |

| This paper analyses the impact of the 2003 CAP reform (the so-called Fischler Reform) and its interaction with the Nitrate Directive on the sustainability of selected arable farming systems in a French region (Midi-Pyrénées). The Nitrate Directive is one of the oldest EU environmental programs designed to reduce water pollution by nitrate from agricultural sources, through a set of measures, defined at regional level, and mandatory for farmers of vulnerable zones. This impact analysis is performed through a bio-economic modelling framework coupling the crop model CropSyst and the farm-based model FSSIM developed, within the EU FP6 SEAMLESS project (Van Ittersum et al., 2008). The 2003 CAP reform was compared first to the continuation of Agenda 2000... |

| We examine producer behavior, resistance evolution, and returns under alternative refuge requirements in an eastern North Carolina region with multiple corn, cotton, and soybean fields infested by a mobile pest. Returns are highest, pyrethroid sprays occur least frequently, and pyrethroid resistance evolution is delayed most effectively with no refuge requirement. Complying with the current 20% refuge requirement costs the producer $8.67 per cotton acre, or $34.21 per non-transgenic insecticidal (Bt) cotton acre. Returns are highest under each refuge requirement when one-toxin Bt cotton is not phased out; however, removal of the technology at the earliest phase-out date minimizes regional pyrethroid sprays. |

| Modellers have examined a wide array of ideal-world scenarios for regulation of greenhouse gases. In this ideal world, all countries limit emissions from all economic sectors; regulations are implemented by intelligent, well-informed forward-looking agents; all abatement options, such as new energy technologies and forestry offsets, are available; trade in goods, services and emission credits is free and unfettered. Here we systematically explore more plausible second-best worlds. While analysts have given inordinate attention to which countries participate in regulation—what we call “variable geometry”—which has a strikingly small impact on total world cost of carbon regulations if international trade in emission credits allows economies to... |

| Water is a key input in the production of many goods and services and under certain conditions can become a critical limiting factor with significant impacts on regional development. This is the case of many agricultural European Mediterranean basins, where water deficit during drought events is partially covered by illegal abstractions, mostly from aquifers, which are tolerated by the authorities. Groundwater overexploitation for irrigation has created in these areas an unprecedented environmental catastrophe that threatens ecosystems sustainability, urban water supply and the current model of development. Market-based drought insurance systems have the potential to introduce the necessary incentives to reduce overexploitation during drought events and... |

| This analysis presents a theoretical model of firm response to border enforcement and evaluates both the intended and unintended effects under two enforcement regimes: destruction versus treatment of contaminated shipments. The results indicate that importers may respond to increased inspection by reducing shipments and decreasing due care. In response to increased pest populations, firms may reduce shipments and increase due care, indicating that an enforcement response may not be necessary. The analysis reveals the importance of the nature of the due-care technology, as well as the relationships underlying the probability of detection, in determining the effects of enforcement. |

| Most of the theoretical literature on enforcing environmental policies focuses on situations in which pollution sources are noncompliant. However, some recent work suggests that these situations will very often involve suboptimal policy designs. Thus, the circumstances under which it is efficient to implement policies that do not motivate full compliance appear to be more limited than most of the literature would imply. In this paper, I identify several circumstances under which regulators may conserve enforcement costs by implementing emissions taxes that firms evade. I demonstrate that a regulator can use a firm’s tax evasion to reduce monitoring effort, but only if its monitoring strategy can be made an increasing function of the firm’s emissions, if... |

| Urban water conservation is typically achieved through prescriptive regulations, including the rationing of water for particular uses and requirements for the installation of particular technologies. A significant shift has occurred in pollution control regulations toward market-based policies in recent decades. We offer an analysis of the relative merits of market-based and prescriptive approaches to water conservation, where prices have rarely been used to allocate scarce supplies. The analysis emphasizes the emerging theoretical and empirical evidence that using prices to manage water demand is more cost-effective than implementing non-price conservation programs, similar to results for pollution control in earlier decades. Price-based approaches also... |
