CONSEQUENCES OF THE CAP REFORM ON FARM ACTIVITIES AND THE ENVIRONMENT – RESULTS OF AN EMPIRICAL STUDY AgEcon
Kantelhardt, Jochen; Ganzert, Christian; Kramer, Christine.
The Common European Agricultural Policy (CAP) reform not only has an impact on agriculture but also has significant effects on nature and the environment. This is specifically caused by decoupling direct payments from agricultural production, which will increase the market orientation of agriculture, and the implementation of Cross Compliance. Based on an empirical analysis of the consequences of the CAP reform in eight German regions, a number of key aspects for a future environmentally friendly development of the agrarian policy are suggested. The results indicate that the CAP reform currently does not increase the proportion of environmentally friendly production systems significantly. Cross Compliance is shown to have certain positive effects; it...

Combining Supply and Demand Estimates for Ecosystem Services from Cropland AgEcon
Ma, Shan; Swinton, Scott M.; Lupi, Frank.
Payment-for-Ecosystem-Services (PES) programs are gaining appeal as flexible approaches to inducing the voluntary provision of ecosystem services (ES). Farmers, who manage agricultural ecosystems, provide important nonmarket ecosystem services to the public by their choice of production inputs and management practices. Although there exist various PES programs in the United States and Europe, we are aware of none that was designed based on a comprehensive understanding of the underlying supply and demand of ecosystem services. Taking advantage of unique, coupled datasets of stated preferences, this paper combines a supply-side cost function of farmers’ willingness to adopt practices that provide increased ES with a demand-side social benefit function of...

Impacts of Border Carbon Adjustments on China’s Sectoral Emissions: Simulations with a Dynamic Computable General Equilibrium Model AgEcon
Bao, Qin; Tang, Ling; Zhang, ZhongXiang; Qiao, Han; Wang, Shouyang.
Carbon-based border tax adjustments (BTAs) have recently been proposed by some OECD countries to level the carbon playing field and target major emerging economies. This paper applies a multi-sector dynamic computable general equilibrium (CGE) model to estimate the impacts of the BTAs implemented by US and EU on China’s sectoral carbon emissions. The results indicate that BTAs will cut down export prices and transmit the effects to the whole economy, reducing sectoral output-demands from both supply side and demand side. On the supply side, sectors might substitute away from exporting toward domestic market, increasing sectoral supply; while on the demand side, the domestic income may be strikingly cut down due to the decrease in export price, decreasing...

Breaking the Impasse in International Climate Negotiations: A New Direction for Currently Flawed Negotiations and a Roadmap for China to 2050 AgEcon
Zhang, ZhongXiang.
China’s unilateral pledge to cut its carbon intensity by 40-45 percent by 2020 relative to its 2005 levels raises both the stringency issue, and given that China’s pledge is in the form of carbon intensity, reliability issues concerning China’s statistics on energy and GDP. Moreover, as long as China’s commitments differ in form from those of other major greenhouse gas emitters, China is constantly confronted with both criticism on its carbon intensity commitment being less stringent and the threats of trade measures. In response to these concerns and to put China in a positive position, this paper will map out a realistic roadmap for China’s specific climate commitments towards 2050, with its main distinguishing features including China taking on absolute...

Energy Balance Climate Models and the Spatial Structure of Optimal Mitigation Policies AgEcon
Brock, William A.; Engstrom, Gustav; Xepapadeas, Anastasios.
We develop a one-dimensional energy balance climate model with heat transportation across locations. We introduce the concept of potential world GDP at time t, and we introduce, through the temperature function, spatial characteristics into the damage function which make damages latitude dependent. We solve the social planner’s problem and characterize the competitive equilibrium. We define optimal taxes on fossil fuels and profit taxes on firms that extract fossil fuels. Our results suggest that if the implementation of international transfers across latitudes is not possible, then optimal taxes are spatially non homogeneous and tend to be lower at the poor latitudes. The degree of spatial differentiation of optimal taxes depend on heat transportation. We...

A farm level assessment of the profitability of Entry Level Scheme participation in the Lincolnshire Wolds AgEcon
Harrison, George R.; Jones, James V.H..
The paper builds on the results of previous studies investigating whether farmers profit by participation in the Entry Level Scheme (ELS). Standard payment levels (derived from points) under ELS are fixed at rates that are expected only to compensate farmers for income foregone and costs incurred. There is no profit element as such. There is therefore no reason to expect participation to be profitable. However farm level examination of the income foregone and costs incurred in previous studies based in other parts of England have shown that this can be achieved. The study is based in the Lincolnshire Wolds, an area dominated by arable farming but with topography and associated natural features that offer some variety in the mix of farming and the measures...

Smoke and Mirrors: The Kyoto Protocol and Beyond AgEcon
van Kooten, G. Cornelis.
The Kyoto Protocol (KP) is considered a necessary first step towards an effective future climate accord. As argued in this paper, however, the KP will likely fail because it has too many loopholes, inadequate governance structures and insufficient compliance provisions. This view is supported by case studies of Canada, Japan and the Netherlands. These countries are unlikely to achieve their self-imposed targets, or, if they do, the costs of compliance will be unacceptably high. Consequently, the difficulty of achieving agreement to reduce global emissions by half (as required to mitigate climate change) is greatly increased.

Certification as a Rationale for Voluntary Agreements AgEcon
Gonzalez, Patrick.
I model the participation of firms in a voluntary agreement as a costly certification process whereby a firm informs the Regulator of its pollution intensity. Without this knowledge, the Regulator imposes the same tax on all firms in a heterogeneous industry, unduly hurting the clean ones with the lowest intensity. Certification allows clean firms to get a tax rebate. It also entails an informational externality as the dispersion of types decreases within the pool of non-participating firms, following an unraveling process. Because participation is a firm’s private decision, there is such a thing as a bad voluntary agreement.

Do Refuge Requirements for Biotechnology Crops Promote Economic Efficiency? Some Evidence for Bt Cotton AgEcon
Livingston, Michael J.; Storer, Nicholas P.; Van Duyn, John W.; Kennedy, George G..
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.

Renewable Energy Subsidies: Second-Best Policy or Fatal Aberration for Mitigation? AgEcon
Kalkuhl, Matthias; Edenhofer, Ottmar; Lessmann, Kai.
This paper evaluates the consequences of renewable energy policies on welfare, resource rents and energy costs in a world where carbon pricing is imperfect and the regulator seeks to limit emissions to a (cumulative) target. We use a global general equilibrium model with an intertemporal fossil resource sector. We calculate the optimal second-best renewable energy subsidy and compare the resulting welfare level with an efficient first-best carbon pricing policy. If carbon pricing is permanently missing, mitigation costs increase by a multiple (compared to the optimal carbon pricing policy) for a wide range of parameters describing extraction costs, renewable energy costs, substitution possibilities and normative attitudes. Furthermore, we show that small...

REGULATING ENVIRONMENTAL THREATS AgEcon
Tsur, Yacov; Zemel, Amos.
Environmental consequences of natural resource exploitation often entail threats of future occurrences of detrimental abrupt events rather than (or in addition to) inflicting a damage gradually. The possibility of abrupt occurrence of climate-change related calamities is a case in mind. The uncertainty associated with the realization of these threats and their public-bad nature complicate the determination of optimal economic response. We analyze the regulation of such environmental threats by means of a Pigouvian hazard tax, based on the shadow cost of the hazard-generating activities. A numerical example illustrates possible effects of the proposed regulation scheme.

Environmental Labeling and Technology Adoption in the Presence of Strategic Interactions AgEcon
Konishi, Yoshifumi.
This manuscript analyzes the effect of binary ecolabeling on the strategic competition of Cournot duopolists in environmental technology and the output market. Under binary labeling, firms' abatement technologies are not directly observable by consumers but are certified if they satisfy preset ecological standards. Given this asymmetry, I set up the regulator's problem as one of choosing a technology standard, or "cutoff," in emissions per unit of output, below which all abatement efficiency levels are certified. The regulatory authority faces a trade-off in choosing the socially optimal cutoff: The regulator would like to raise the standard to reduce emissions but needs to lower it in order to induce technology adoption. There are three important...

MARGINAL ABATEMENT COST CURVES FOR UK AGRICULTURAL GREENHOUSE GAS EMISSIONS AgEcon
Moran, Dominic; MacLeod, Michael J.; Wall, Eileen; Eory, Vera; McVittie, Alistair; Barnes, Andrew Peter; Rees, Robert; Topp, Cairistiona; Moxey, Andrew.
This paper addresses the challenge of developing a ‘bottom-up’ marginal abatement cost curve (MACC) for greenhouse gas emissions from UK agriculture. A MACC illustrates the costs of specific crop, soil, and livestock abatement measures against a ‘‘business as usual’’ scenario. The results indicate that in 2022 under a specific policy scenario, around 5.38 MtCO2 equivalent (e) could be abated at negative or zero cost. A further 17% of agricultural GHG emissions (7.85 MtCO2e) could be abated at a lower unit cost than the UK Government’s 2022 shadow price of carbon (£34 (tCO2e)-1). The paper discusses a range of methodological hurdles that complicate cost-effectiveness appraisal of abatement in agriculture relative to other sectors.

The Linkages between Energy Efficiency and Security of Energy Supply in Europe AgEcon
Bigano, Andrea; Arigoni Ortiz, Ramon; Markandya, Anil; Menichetti, Emanuela; Pierfederici, Roberta.
It can be argued that one way to reduce the dependence from external energy sources, is simply to reduce the demand for energy. Energy savings may thus be considered a policy priority when concerns for energy security are particularly strong. Drawing on an original econometric approach, we check whether policies and measures that affect indicators of energy efficiency performance have an analogous effect on security of supply indicators, both at the whole economy level and within the main sectors of energy use in the EU 15 countries and Norway. Our analyses show that the indicators studied are affected by a number of policies and measures; however very few of them seem able to tackle effectively and simultaneously, energy efficiency, carbon efficiency and...

Adverse Selection in the Environmental Stewardship Scheme: Evidence in the Higher Level Stewardship Scheme? AgEcon
Quillerou, Emmanuelle; Fraser, Rob W.; Fraser, Iain.
The Environmental Stewardship Scheme provides payments to farmers for the provision of environmental services based on foregone agricultural income. This creates a potential incentive compatibility problem which, combined with an information asymmetry on farm land heterogeneity, could lead to adverse selection of farmers into the Scheme and therefore reduced cost-effectiveness of the Scheme. This reduced cost-effectiveness would be represented by a systematic overpayment of farmers for the land enrolled into the Scheme, compared to the opportunity cost of production. This paper examines the potential adverse selection problem affecting the higher tier of the Environmental Stewardship, the Higher Level Stewardship, using a principal agent framework combined...

Police-powers, regulatory takings and the efficient compensation of domestic and foreign investors AgEcon
Aisbett, Emma; Karp, Larry S.; McAusland, Carol.
In customary international and public law, “takings” resulting from regulations designed to protect the public good are generally excluded from compensation rules; this exclusion is known as a police powers carve-out (PPCO). Increasingly, this PPCO is being challenged, particularly in international investment law. This paper analyzes the efficiency properties of a PPCO in a model with endogenous regulation, investment and entry. We design a one-parameter family of carve-out/compensation schemes that induce efficient regulation and firm level investment even when the regulator suffers fiscal illusion and the social benefit from regulation is private information to the regulator. We show that offering a carve-out reduces the subsidy to risky industry...
