Organic Farming and the New CAP - Results for the Austrian Agricultural Sector AgEcon
Schmid, Erwin; Sinabell, Franz.
In 2003, the Common Agricultural Policy (CAP) has been reformed and decoupling direct payments from farm output is one of its core elements. We estimate the likely responses in organic product supply due to the reform at regional and sectoral levels. In addition, we analyse how the new programme for rural development, to be implemented in 2007, might affect organic farming. Our results show that organic farming will become more attractive after the 2003 CAP reform in Austria. Our results support the view that interactions among agri-environmental measures affect farmers' choice to maintain, abandon or adopt organic farming practices.

Panel Data Evidence on the Determinants of Non-Timber Forest Products Extraction: The Case of Xate in Mexico AgEcon
Lopez-Feldman, Alejandro.
This paper examines the determinants behind households' decisions regarding non-timber forest products extraction. Data from Mexico is used to estimate a selection model. Results show that individuals with low levels of human capital are more likely to extract than other individuals; the same is true for individuals from poor households.

Plagiarism Without Apology--Systematic Integration of Available Information in a Long Run Agricultural Outlook AgEcon
Witzke, Heinz Peter; Britz, Wolfgang.
In the context of a long run agricultural outlook on behalf of the European Environmental Agency a new methodology has been developed to systematically integrate external forecasts into a quite detailed agricultural sector model. External forecasts usually provide estimates for the exogenous variables in modelling work and frequently they are also used for comparisons and potential reassessment of empirical specifications. The innovative characteristic of this study is that expert forecasts have been used to specify parameter changes expressing structural change affecting behavioural functions. The outlook was therefore set up as a simultaneous estimation and forecasting effort which permitted to integrate various, usually contradictory expert forecasts...

Prescriptive use of Environmental Indices: A "How To" Guide for Conservation Programs AgEcon
Cattaneo, Andrea.
A framework for analyzing conservation programs that rank applications using environmental indices is presented. We derive the optimal bid from the farmer's perspective for both land retirement and working lands agri-environmental payment programs and we analyze how these solutions depend on program design parameters. The distinction is made between environmental objectives based on whether the farmer exercises control or not over the level proposed in a bid to participate in a program. The optimization model is solved analytically for two cases - a land retirement and a working lands program - highlighting the differences in the results.

Pricing Benefit Externalities of Soil Carbon Sequestration in Multifunctional Agriculture AgEcon
Hartell, Jason G..
“Multifunctionality” emphasizes the benefit externality properties of nonfood products that coincide with agricultural commodity production, some of which also have public-good properties. However, determining the willingness to pay for local benefit externalities is seen as necessary but daunting. This paper pursues the idea that the valuation process might first start by estimating the incentives required to supply various levels of a benefit externality. With the use of carbon sequestration through the adoption of no-till cultivation as an example of a multifunctional benefit externality, mathematical programming is used to derive representative price schedules. The implication for incentive prices are examined in light of risk aversion.

Private Options to Use Public Goods: Exploiting Revealed Preferences to Estimate Environmental Benefits AgEcon
Snyder, Lori D.; Stavins, Robert N.; Wagner, Alexander F..
We develop and apply a new method for estimating the economic benefits of an environmental amenity. The method fits within the household production framework (Becker 1965), and is based upon the notion of estimating the derived demand for a privately traded option to utilize a freely-available public good. In particular, the demand for state fishing licenses is used to infer the benefits of recreational fishing. Using panel data on state fishing license sales and prices for the continental United States over a fifteen-year period, combined with data on substitute prices and demographic variables, a license demand function is estimated with instrumental variable procedures to allow for the potential endogeneity of administered prices. The econometric...

Productivity and Environmental Performance in Marketing Cooperatives: Incentive Schemes on the Horticultural Sector AgEcon
Galdeano-Gomez, Emilio; Cespedes-Lorente, Jose; Rodriguez-Rodriguez, Manuel.
The object of the present paper is to analyze the productivity of marketing cooperatives incorporating environmental inputs/outputs. In the European agricultural policy, expectations for attaining sustainable and competitive agriculture lie to a great extent on the cooperative sector's ability to adapt to the new market conditions. These challenges have led marketing cooperatives in the fruit and vegetables sector to consider improvement in productivity and sound environmental performance. In this sector environmental management was intensified by the Common Agrarian Policy (CAP) through incentives on the so-called Operative Programs (OP). The present study analyses the total factor productivity (TFP) related to environmental variables in this sector using...

Productivity and Quality-Environmental Changes in Marketing Co-operatives: An Analysis on the Horticultural Sector AgEcon
Galdeano-Gomez, Emilio; Cespedes-Lorente, Jose; Rodriguez, Manuel Rodriguez.
The object of the present paper is to analyse productivity incorporating quality-environmental changes in marketing co-operatives. Firstly, it reviews competitiveness factors in the current European agri-food market, especially in relation to the fruit and vegetables sector. Secondly, the productivity trend is studied empirically using nonparametric methods (Malmquist indices) and taking as reference panel data of Andalusian horticultural co-operatives for the period 1994-2001. For this purpose productivity is decomposed into technological change, efficiency and quality-environmental change. Additionally, the correlation of these results with other economic variables is analysed. The indicators obtained show a relevant increase in efficiency for the period...

Risk Valuation in the Presence of Risky Substitutes: An Application to Demand for Seafood AgEcon
Huang, Ju-Chin; Haab, Timothy C.; Whitehead, John C..
We attempt to value health risks by combining traditional demand impact analysis with direct elicitation of individuals’ risk perceptions of food safety. We examine the impact of multiple risks of related goods on consumption of a risky good. We argue that the consumption of a risky good depends on both its absolute risk level and its relative risks to other risky goods. Seafood consumption in eastern North Carolina was studied. We elicited, in a survey, individual perceived risks as reference points to derive the economic value of reducing health risk in seafood consumption. Revealed and stated data were combined to trace out demand changes in response to absolute and relative risk reductions. Our results show that seafood consumption is affected by the...

The Complex Interaction of Markets For Endangered Species Products AgEcon
Fischer, Carolyn.
Economic models of trade in endangered species products often do not incorporate four focal arguments in the policy debate over trade bans: 1) law-abiding consumers may operate in another market, separate from illegal consumers, that trade would bring online; 2) legal trade reduces stigma, which affects demand of law-abiding consumers; 3) laundering may bring illegal goods to legal markets when trade is allowed; 4) legal sales may affect illegal supply costs. This paper analyzes systematically which aspects of these complicated markets, separately or in combination, are important for determining whether limited legalized trade in otherwise illegal goods can be helpful for achieving policy goals like reducing poaching.

The Economic and Policy Setting of Renewable Energy: Where Do Things Stand? AgEcon
Darmstadter, Joel.
This paper looks at the status and prospects of renewables-with particular emphasis on windpower-in the electric power sector. Although renewables account for a steadily rising share of electricity generation in various countries, their role remains small in absolute terms. In part, this is because of technological progress of and successful competition from fossil-fueled generation-notably, combined cycle gas turbines. While diminishing, subsidies continue to be indispensable to the use of renewables in most places. Viability of renewables-based electricity is undermined by the cost of externalities for which fossil energy combustion is only partially charged. A number of countries (and states in the U.S.) have launched obligatory requirements for...

The Future of European Agriculture - An Updated Outlook AgEcon
Isoard, Stephane; Witzke, Heinz Peter.
This paper reports the results of a European agricultural outlook exercise that updates former studies in three ways, i.e. in terms of timeframes, spatial coverage and policy context. This updated European agricultural outlook constitutes a key component of the forthcoming 'State of the Environment and Outlook report' of the European Environment Agency (EEA). Both activity variables and environmental indicators are reported for a baseline projection and alternative scenarios. The main findings include the following: European harvested land is expected to continue to be primarily used to fodder activities and production of cereals (80% of total area); yields increase is projected to be the main source of production growth in Europe over the next 20...

The Impacts of Alternative Policy Scenarios on Multifunctionality AgEcon
Lehtonen, Heikki; Lankoski, Jussi E.; Niemi, Jyrki S.; Ollikainen, Markku.
This paper provides first results of the sector model approach to analyze the effects of alternative policy scenarios on the multifunctional role of Finnish agriculture. In terms of environmental non-commodity outputs we focus on nutrient runoffs, landscape diversity and biodiversity. As regards to socio-economic outputs our focus is on direct and indirect agricultural labour force. The results suggest that while partial de-coupling agricultural supports from production is not likely to result in any drastic decline of agricultural production the amount of green fallow will increase considerably. As a result, the agricultural land will become biologically richer. The agricultural labour force is likely to decrease substantially irrespective of agricultural...

The Market-based Lead Phasedown AgEcon
Newell, Richard G.; Rogers, Kristian.
The U.S. lead phasedown was effective in meeting its environmental objectives, and did so more quickly with the allowance of permit banking. The marketable lead permit system was highly costeffective, saving hundreds of millions of dollars relative to comparable policies not allowing trading or banking. Estimates suggest that transaction costs brought about only a modest reduction in program efficiency. The market-based nature of the program also provided incentives for more efficient adoption of new lead-removing technology, relative to a uniform standard. Distributionally, it is likely that the program was actually more responsive to the cost concerns of small refiners than a similar uniform standard would have been. The flexibility of the program likely...

The Relative Impacts of U.S. Bio-Fuel Policies on Fuel-Energy Markets: A Comparative Static Analysis AgEcon
Kim, C.S.; Schaible, Glenn D.; Daberkow, Stan G..
Rapidly declining gasoline prices from their record high during the summer of 2008, while ethanol prices remained relatively high, made it difficult for many bio-fuel policy modelers to fully explain the impacts of U.S. bio-fuel policies on fuel prices. Using profit-maximization models for blenders, refiners, and distillers, we conduct a comparative static analysis to measure the relative magnitudes of the impacts of tax credits and blending mandates on fuel-energy market equilibrium prices. Our results indicate that first, the prices of all fuels including conventional gasoline, ethanol, and blended gasoline decline as the biofuel tax credit increases, but they increase as the rate of the blending mandate increases. Second, the shadow value of a blending...

Timber Supply Model 96: A Global Timber Supply Model with a Pulpwood Component AgEcon
Sedjo, Roger A.; Lyon, Kenneth S..
This study involves an update of our earlier Timber Supply Model, which was fully developed in our book, The Adequacy Of Global Timber Supply by Sedjo and Lyon (1990), published by Resources for the Future. The new version, called Timber Supply Model 1996 (TSM96), uses an economic market supply/demand approach to project an intertemporal time path of the world's price and output level of industrial wood. As did the original TSM, the TSM96 provides projections of the time path of the equilibrium output levels of the several regions into which the world has been subdivided. A major new feature of TSM96 is that industrial wood, treated as homogeneous in the earlier study, has be subdivided into two different wood types -- pulpwood and solidwood. The supply of...

Transgenic Trees: Implementation and Outcomes of the Plant Protection Act AgEcon
Sedjo, Roger A..
The responsibility for protecting U.S. agriculture from pests and diseases is assigned by the Federal Plant Pest Act (FPPA) to the Animal and Plant Health Inspection Service (APHIS) of the Department of Agriculture. The Plant Protection Act (Title 7 U.S.C. Sections 7701 et seq.) gives Aphis statutory authority over genetically modified organisms (GMO), in effect assigning to APHIS a related responsibility of determining whether a genetically altered plant, crop, or tree is likely to pose unacceptable risks to the environment. Although APHIS has considerable experience with crop plants, it has only limited experience with trees. Yet the possible benefits of applying genetic engineering to trees are substantial and include industrial wood production and...

Transition to Sustainable Tropical Land Management AgEcon
Burger, Kees.
Following the example of Tiffen et al. on Machakos, Kenya, new macro-based evidence was collected in Machakos, the neighbouring Kitui district and in Benin, Cameroon and the Philippines, to assess the factors à la Boserup, inducing transitions towards sustainable land management, such as terracing, stone bands etc. We find that relative scarcity of land can be seen to induce technical changes, in the sense of Hayami & Ruttan, that correspond to the new relative scarcity, making higher man-land ratios the optimal choice.

Wilderness and Primitive Area Recreation Participation and Consumption: An Examination of Demographic and Spatial Factors AgEcon
Bowker, James Michael; Murphy, D.; Cordell, H. Ken; English, Donald B.K.; Bergstrom, John C.; Starbuck, C. Meghan; Betz, Carter J.; Green, Gary T..
This paper explores the influence of demographic and spatial variables on individual participation and consumption of wildland area recreation. Data from the National Survey on Recreation and the Environment are combined with geographical information system-based distance measures to develop nonlinear regression models used to predict both participation and the number of days of participation in wilderness and primitive area recreation. The estimated models corroborate previous findings indicating that race (black), ethnicity (Hispanic), immigrant status, age, and urban dwelling are negatively correlated with wildland visitation, while income, gender (male), and education positively affect wildland recreation participation and use. The presence of a...
