A Net Present Value Model of Natural Gas Exploitation in Northern Alberta: An Analysis of Land Values in Woodland Caribou Ranges AgEcon
Hauer, Grant; Adamowicz, Wiktor L.; Jagodzinski, Robert.
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...

A Numerical Analysis of Optimal Extraction and Trade of Oil under Climate Policy AgEcon
Massetti, Emanuele; Sferra, Fabio.
We introduce endogenous investments for increasing conventional and non-conventional oil extraction capacity in the integrated assessment model WITCH. The international price of oil emerges as the Nash equilibrium of a non-cooperative game. When carbon emissions are not constrained, oil is used throughout the century, with unconventional oil taking over conventional oil from mid-century onward. When carbon emissions are constrained, oil consumption drops dramatically and the oil price is lower than in the BaU. Unconventional oil is not extracted. Regional imbalances in the distribution of stabilisation costs are magnified and the oil-exporting countries bear, on average, costs three times larger than in previous estimates.

A Socioeconomic Survey for the Recovery and Exploitation of the Terraced Vineyards of the Costa Viola (Calabria, Italy) AgEcon
Nicolosi, Agata; Cambareri, Domenico; Petulla, Mariangela.
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...

A Tale of Two Countries: Emissions Scenarios for China and India AgEcon
Massetti, Emanuele.
The aim of the paper is to present evidence that China and India are, and will remain, two very different actors in international negotiations to control global warming. We base our conclusions on historical data and on scenarios until 2050. The Business-as-Usual scenario (BaU) is compared to four Emissions Tax scenarios to draw insights on major transformations in energy use and in energy supply and to assess the possible contribution of China and India to a future international climate architecture. We study whether or not the Copenhagen intensity targets require more action than the BaU scenario and we assess whether the emissions reductions induced by the four tax scenarios are compatible with the G8 and MEF pledge to reduce global emissions by 50% in...

Adoption of Resource Conservation Technologies in Indo-Gangetic Plains of India: Scouting for Profitability and Efficiency AgEcon
Singh, N.P.; Singh, R.P.; Kumar, Ranjit; Vashist, A.K.; Khan, Farida; Varghese, Nisha.
This study has evaluated the superiority of resource conservation technologies (RCTs) over conventional methods of cultivation and has identified the factors influencing adoption of these technologies. It has provided succinct evidences from four states — Bihar, Haryana, Punjab and Uttar Pradesh — by comparing the adopters and non-adopters of RCTs in the rice-wheat cropping system of the Indo-Gangetic Plains of India. The study has highlighted superiority of RCTs over the conventional practices in terms of cost saving and efficient inputs-use. However, there is a need to internalize the RCTs in their totality by applying plans and strategies based on local dynamics. The study has suggested the need of policy formulations for dissemination and wider...

Assessing the Risk of Oil Spills in the Mediterranean: the Case of the Route from the Black Sea to Italy AgEcon
Bigano, Andrea; Sheehan, Paul.
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...

Comparing the Cost-Effectiveness of Water Conservation Policies in a Depleting Aquifer: A Dynamic Analysis of the Kansas High Plains AgEcon
Ding, Ya; Peterson, Jeffrey M..
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...

COPPER CRISIS AND AGRICULTURAL RENAISSANCE IN ZAMBIA: AN ECONOMY-WIDE ANALYSIS AgEcon
Lofgren, Hans; Robinson, Sherman; Thurlow, James.
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...

Corruption, Development and the Curse of Natural Resources AgEcon
Pendergast, Shannon M.; Clarke, Judith A.; van Kooten, G. Cornelis.
In 1995, Jeffrey Sachs and Andrew Warner found a negative relationship between natural resources and economic growth, and claimed that natural resources are a curse. Their work has been widely cited, with many economists now accepting the curse of natural resources as a welldocumented explanation of poor economic growth in some economies (e.g., Papyrakis and Gerlagh, 2004; Kronenberg, 2004). In this paper, we provide an alternative econometric framework for evaluating this claim, although we begin with a discussion of possible explanations for the curse and a critical assessment of the extant theory underlying the curse. Our approach is to identify natural resources that have the greatest rents and potential for exploitation through rent-seeking agents....

Economic Efficiency of Short-Term Versus Long-Term Water Rights Buyouts AgEcon
Wheeler, Erin A.; Golden, Bill B.; Johnson, Jeffrey W.; Peterson, Jeffrey M..
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.

Efficiency Improving Fossil Fuel Technologies for Electricity Generation: Data Selection and Trends AgEcon
Lanzi, Elisa; Verdolini, Elena; Hascic, Ivan.
This paper studies innovation dynamics in efficiency improving electricity generation technologies as an important means of mitigating climate change impacts. Relevant patents are identified and used as an indicator of innovation. We find that patenting in efficiency improving technologies has mostly been stable over time, with a recent decreasing trend. We also find that majority of patents are first filed in OECD countries and only then in non-OECD or BRIC countries. Conversely, non-OECD and BRIC countries apply for patents that are mostly marketed domestically. This result shows that there is significant technology transfer in the field of efficiency improving technologies for electricity production. This flow of know-how is likely to contribute to...

Environmental Kuznets Curves for Carbon Emissions: A Critical Survey AgEcon
Aslanidis, Nektarios.
The empirical finding of an inverse U-shaped relationship between per capita income and pollution, the so-called Environmental Kuznets Curve (EKC), suggests that as countries experience economic growth, environmental deterioration decelerates and thus becomes less of an issue. Focusing on the prime example of carbon emissions, the present article provides a critical review of the new econometric techniques that have questioned the baseline polynomial specification in the EKC literature. We discuss issues related to the functional form, heterogeneity, “spurious” regressions and spatial dependence to address whether and to what extent the EKC can be observed. Despite these new approaches, there is still no clear-cut evidence supporting the existence of the...

Groundwater Policy Research: Collaboration with Groundwater Conservation Districts in Texas AgEcon
Johnson, Jeffrey W.; Johnson, Phillip N.; Guerrero, Bridget L.; Weinheimer, Justin; Amosson, Stephen H.; Almas, Lal K.; Golden, Bill B.; Wheeler-Cook, Erin.
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.

Increasing Profitability of Small Scale Orchard Producers through Optimizing Replacement Rate: The Case Study of Ghana AgEcon
Mahrizal; Nalley, Lawton Lanier; Dixon, Bruce L.; Popp, Jennie S. Hughes.
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...

Irrigation Restriction and Biomass Market Interactions: The Case of the Alluvial Aquifer AgEcon
Popp, Michael P.; Nalley, Lawton Lanier; Vickery, Gina B..
The U.S. Geological Survey has determined that irrigation in Arkansas’ Delta is unsustainable. This study examines how irrigation restrictions would affect county net returns to crop production. It also considers the effect of planting less water-intensive bioenergy crops—switchgrass and forage sorghum—in the event biofuel markets become a reality. Results suggest that sustainable irrigation restrictions without bioenergy crops would decrease producer returns by 28% in the region. Introducing these alternative crops would both reduce groundwater use and may restore state producer returns, albeit with significant spatial income redistribution to crop production throughout the state.

Irrigation Technology Adoption Under Factor Price Uncertainty: Groundwater- Irrigated Production in Nebraska, 1960 -- 2005 AgEcon
Savage, Jeff; Brozovic, Nicholas.
The development of groundwater-irrigated production technologies, fed by water from the Ogallala Aquifer, facilitated the development of agriculture in the High Plains region of the United States that began during the 1960s. The current rate of pumping for irrigation in the region is causing the aquifer to be depleted in many areas, which is cause for concern from a socioeconomic and environmental standpoint. The goal of this paper is to assess the factors that affect the decision to adopt groundwater-irrigated production by farmers, in the presence of risk differentiated by heterogeneous farmland quality and groundwater depth. A binary choice model of adoption is estimated for Nebraska, from 1960 – 2005. The results suggest that farmers consider climate...

Oil Price Forecast Evaluation with Flexible Loss Functions AgEcon
Bastianin, Andrea; Manera, Matteo; Markandya, Anil; Scarpa, Elisa.
The empirical literature is very far from any consensus about the appropriate model for oil price forecasting that should be implemented. Relative to the previous literature, this paper is novel in several respects. First of all, we test and systematically evaluate the ability of several alternative econometric specifications proposed in the literature to capture the dynamics of oil prices. Second, we analyse the effects of different data frequencies on the coefficient estimates and forecasts obtained using each selected econometric specification. Third, we compare different models at different data frequencies on a common sample and common data. Fourth, we evaluate the forecasting performance of each selected model using static forecasts, as well as...
