| Intrasectoral issues have received relatively little attention in analysis of the distributional consequences of natural resource policy decisions. This paper presents a framework for such analysis and examines how intrasectoral issues can change intertemporally, focusing on water policy in agriculture. The results show that income distribution among farmers depends on the stochastic structure of production and marketing, the size distribution of farms, credit market imperfections, and risk aversion in farmer decisions. It is shown that the introduction of water conservation policies may lead to more equitable income distribution among farmers. |

| This paper presents a framework to determine optimal resource allocation over time for the production of a good by heterogeneous producers who generate a stock externality. We analyze the optimal intertemporal and quality-specific combination of abatement strategies at the source given by a change in the intensity of production and in the chosen technology, and/or removal of existing pollution stock. The results show how the specifications of the production and the emission functions affect technology adoption and the design of the optimal intertemporal combination of source and stock abatement strategies. Moreover, the paper shows that regulation at the intensive margin cannot be considered as a substitute for a regulation at the extensive margin. The... |

| Economic research generates a wide array of benefits. These include information, technological change, and improved policy. There are few quantitative studies of the benefits of economic research, and some benefits may be misattributed to biological and physical research. To be productive, economic research must be transmitted and the user must be able to use it. Therefore, investment in extension outreach and economic literacy are important to improve its impact. Even casual observation suggests that economic research is valuable, but noneconomists must be convinced of this. Since benefits are likely to be concentrated in a small number of successful projects, a useful approach to the assessment of the benefits of research is to identify these projects... |

| The objective of this research is to determine the contribution of recent agricultural policy reforms in the E.U. on the use of crop protection products. Specifically, we concentrate on the 1992 CAP reforms. Our theoretical model adopts the multi-output generalization of the Lichtenberg-Zilberman damage control technology model developed by Chambers and Lichtenberg. In the empirical application, farm-level data for a sample of French farms are utilized. Results suggest that price effects on the usage of crop protection products are always more elastic than the compensatory payment effects. This result indicates that a policy reform consisting of a reduction in price-support measures in favor of direct payments to farmers, such as the 1992 CAP reform,... |

| This article argues that the existing maze of pesticide policies reflects the multidimensionality of side effects of pesticide use that cannot be addressed by uniform policies. Pesticide policies will improve as (a) economic literacy among natural scientists and policymakers increases; (b) economic models of pesticide use and agricultural production in general better incorporate biological consideration; (c) benefit-cost criteria are introduced to determine regulations of pesticide, and (d) policies are enacted that take advantage of new information technologies and enable increased reporting of pesticide use. Moving from bans toward financial incentives and flexible policies that will allow chemical use where the benefit-cost ratios are high will improve... |

| Our paper looks at how price volatility in the Brazilian ethanol industry changes over time and across markets. Demand and supply forces in the energy and food markets are likely to ensure that crude oil, ethanol and feedstock prices co-move in the long-run. Hence, when assessing price volatility changes and spillovers in the ethanol industry, one should also pay attention to the notion of cointegration. Until recently, the methods proposed to estimate cointegration relationships, have not explicitly considered time varying volatility in the data. Seo (2007) suggests an estimator of the cointegration vector that explicitly models conditional heteroskedasticity. More specifically, he proposes a maximum likelihood estimator that estimates the error... |

| 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. |

| Major externality cases are random accidents which are not adequately addressed by the deterministic environmental policy literature -‐ that of Pigouvian taxes, abatement subsidies and cap-‐and-‐trade. We consider a risk-‐neutral industry where firms control the probability and Severity of accidents by preventive and responsive choices, but asymmetric information means Government only observes outcomes. We show that even without intervention, some care will be taken, however -‐ we identify three policies that lead to the optimal solution: strict liability, a Stochastic subsidy, and a mandatory mutual insurance scheme. The subsidy policy may be very costly to taxpayers, especially when prevention affects the probability of accident occurrence, and... |

| The growing importance of economic factors in farmers decision to go organic has raised interest in characterizing the economic behavior of organic versus conventional farms. Published analyses so far have not considered differential uncertainties and farmers risk preferences between conventional and organic practices when comparing these techniques. Our article attempts to assess this issue. We use a model of farmer decision under risk to analyze the differential values between Spanish COP organic and conventional farms and to assess the incentives for adoption of organic practices. Results show that organic and conventional farms do have different abilities to control production risk as well as different risk preferences. Organic price premiums and... |

| This study presents a framework to analyze how uncertainty about product attributes affects consumers' WTP for brand name products over generic ones, incorporating key elements of a random utility model and product attribute models. We found that in comparison to electronics, clothing, and processed food, consumers buy brand name vegetables and fruits mainly because of quality uncertainty, and they can easily reduce uncertainty of product quality of fresh vegetables and fruits by seeing, touching, smelling, and tasting. Hence, consumers are less willing to pay for brands of fresh vegetables and fruits. However, simulation results show that brands of fresh fruits and vegetables may have a similar price premium as other products, but they lack the market... |

| This paper studies the extent to which decoupled income support measures in agriculture can have production implications both at the extensive and intensive margins. We develop a theoretical framework that analyzes production responses of agricultural producers to apparently decoupled payments, by explicitly considering risk attitudes and uncertainty. We use farm-level data collected in Kansas to estimate the model. Technology and risk preference parameters are jointly estimated. Results show that though lump sum payments are not fully decoupled in the presence of risk and uncertainty, their effects on agricultural production are likely to be of a very small magnitude. |

| This paper derives a method to quantify the impact of biofuel on fuel markets, assuming that these markets are dominated by cartel of oil-rich countries, and that prices in these countries are set to maximize the sum of domestic consumer and producer surplus, leading to a wedge between domestic and international fuel prices. We model this behavior by applying the optimal export tax model (henceforth, the cartel-of-nations model) to the fuel markets. Using data from 2007 to calibrate the model, we show that the introduction of biofuels reduces global fossil fuel consumption and international fuel prices by about 1% and 2%, respectively. We identify large differences between the effects of introducing biofuels using the cartel-of-nations model, in contrast... |
