| This paper is the first to assess operational and probabilistic externalities of oil extraction and transportation to Europe on the basis of a comprehensive evaluation of realistic future oil demand-supply scenarios, of the relative relevance of import routes, of the local specificities in terms of critical passages and different burdens and impacts along import routes. The resulting externalities appear reasonable both under the assumption of high future demand and under low demand. Estimates range from 2.32 Euro in 2030 in the low demand scenario to 2.60 Euro in 2010 in the high demand scenario per ton of imported oil. |

| This report was prepared for the purpose of providing background documentation of inputs to be used in mathematical programming models and papers, which are being prepared for our research project: Ecological and economic tradeoff analysis of conservation strategies for woodland caribou. The report presents a simple net present value model of resource and land value for natural gas in northern Alberta. The variables in the model include costs (drilling, seismic, operating and capital); geological variables (stratigraphic intervals, booked reserves, future reserves); drilling variables (well densities, drilling success rates, and drilling depths); production data and prices. Each variable is described in detail and methods of derivation are provided. A map... |

| Because of the decline of the Ogallala Aquifer, water districts, regional water managers, and state water officers are becoming increasingly interested in conservation policies. This study evaluates both short-term and long-term water rights buyout policies. This research develops dynamic production functions for the major crops in the Texas Panhandle. The production functions are incorporated into optimal temporal allocation models that project annual producer behavior, crop choices, water use, and aquifer declines over 60 years. Results suggest that long-term buyouts may be more economically efficient than short-term buyouts. |

| In this study, the prospects of wind power at the global level are reviewed. Existing studies indicate that the earth’s wind energy supply potential significantly exceeds global energy demand. Yet, only 1% of the global electricity demand is currently derived from wind power despite 40% annual growth in wind generating capacity over the last 25 years. More than 98% of total current wind power capacity is installed in the developed countries plus China and India. Existing studies estimate that wind power could supply 7% to 34% of global electricity needs by 2050. Wind power faces a large number of technical, financial, institutional, market and other barriers. To overcome these, many countries have employed various policy instruments, including capital... |

| This study sets out to empirically estimate the optimum annual replacement rate and age of cocoa trees in order to maximize the net present value of four common cocoa production systems. The study examines the costs and returns of four common cocoa production systems in Ghana associated with changes in cocoa prices, fertilizer prices, inflation rates, and labor prices. While this study focuses on cocoa, the methodology is applicable to any perennial crop. This study uses empirical yield curves and cost of production data from Ghana to determine when and what percentage of a cocoa orchard should be replaced annually to maximize net present value of revenues over time. Successive versions of the model are solved to determine how input and output price... |

| Recent major spills on European coasts have highlighted the primary policy relevance for the EU of oil spills. This paper assesses the risks related to carrying oil to the EU along the route from the Russian Black Sea coast to Sicily, Italy (one of the most congested and strategically relevant European import routes). We develop a methodology based on Fault Tree Analysis, and we apply it to the most likely causes of an oil spill. We couple the resulting probabilities with data on expected spill size, types of oil carried and cleanup costs, to estimate expected costs for cleanup and loss of cargo. The route analysed appears to be a risky one; there is a high to very high risk of a spill along this route. The Turkish Straits turn out to be the major... |

| A puzzling piece of empirical evidence suggests that countries rich in natural resources tend to have dismal economic performance. This paradigm has come to be known as the “resource curse”. This paper deals with the role of institutional quality in explaining the transmission mechanism of the resource curse. I attempt to explain this phenomenon by using the index of economic freedom developed by the Fraser Institute as a proxy for the quality of institutions. The outcomes of the linear and non-linear interactions between resource abundance and institutional quality turn out to be the key elements that determine the intensity, if existent, or otherwise of the resource curse. Rather than look at cross country data like many others, I focus on the 10... |

| The unique nature of the Ogallala Aquifer presents interesting and confounding problems for water policymakers who are coping with changing groundwater rules in Texas. The purpose of this article is to link previous efforts in water policy research for the Ogallala Aquifer in Texas with current collaborations that are ongoing with regional water planners. A chronological progression of economic water modeling efforts for the region is reviewed. The results of two recent collaborative studies are presented that provide estimates of impacts of alternative policies on groundwater saturated thickness, water use, net farm income, and regional economic activities. |

| The effect of insecure ownership on ordinary investment and on the exploitation of natural resources is examined. Insecure ownership is characterized as a positive probability that a typical asset or its future return will be confiscated. For empirical analysis, the probability of confiscation is modeled as a function of observable political attributes of countries, principally the type of government regime in power (democratic versus nondemocratic) and the prevalence of political violence or instability. A general index of ownership security is estimated from the political determinants of economy wide investment rates, and then introduced into models of petroleum and forest use. Ownership risk is found to have a significant, and quantitatively important... |

| Zambia's strong dependence on copper exports has suppressed other tradables sectors, indicative of a Dutch disease phenomenon. The current copper crisis will have strong economic effects, possibly reversing such Dutch disease effects. We use a computable general equilibrium model built around a 1995 social accounting matrix to simulate the short- and long-run effects of two scenarios that reflect the current crisis, a 20 percent reduction in world copper prices and a complete collapse of copper mining. Compared to the short run, the long run is characterized by more flexibility in production technology and capital allocation. Both scenarios require a significant reduction in the "non-copper" trade deficit, absorption, and household consumption. The... |

| This research analyzes two groundwater conservation policies in the Kansas High Plains located within the Ogallala aquifer: 1) cost-share assistance to increase irrigation efficiency; and 2) incentive payments to convert irrigated crop production to dryland crop production. To compare the cost-effectiveness of these two policies, a dynamic model simulated a representative irrigator’s optimal technology choice, crop selection, and irrigation water use over time. The results suggest that the overall water-saving effectiveness can be improved when different policy tools are considered under different conditions. High prevailing crop prices greatly reduce irrigators’ incentive to give up irrigation and therefore cause low enrollment and ineffectiveness of the... |

| The new model of rural development, based on the recognition of the economic, social and environmental function of the European agriculture, mainly headed to make strategies of intervention concerning about, from one side, the competitive ability of the agricultural and agro-industrial enterprises, and, from the other, the increasing of the economic, human, environmental and historical-cultural resources. In such context the multi-functional role of agriculture becomes central and the agricultural operators have to adapt themselves to items (the territories, the rural societies, the consumers, etc.) and to different prescriptions related to demands linked up with the productivity and/or the territory (defence of the ground, of the landscape, of the... |

| The fast-growing US ethanol industry has historically been characterized by large downstream investments made by farmers. The authors assess the value which the stock market may hold for downstream investment by farmers as well as by ethanol manufacturers themselves. The model framework used herein expands on the original VEST framework developed by Siebert, Jones and Sporleder. A word of caution, the model herein is not intended to provide an on-going, risk-reducing business strategy. However, it can and does provide a quick method to calculate the reasonableness of a downstream investment request that a farmer (or any business person) might be challenged to consider. Although virtual stock market investments may certainly assist in value added... |
