Use of Penalties and Rewards in Agri-Environmental Policy AgEcon
Yano, Yuki; Blandford, David.
Achieving high compliance rates in incentive-based agri-environmental schemes is an important issue. This paper explores the use of a mixed penalty-reward approach under heterogeneous compliance costs. Specifically, we examine the use of a “compliance reward” under asymmetric information and output price uncertainty. Using a budget-neutral approach, three possible sources of financing are considered: 1. funds obtained by reducing monitoring effort; 2. the proceeds of fines collected from participating farmers who are inspected and found not to be in compliance; and 3. money saved by reducing the number of farmers enrolled. We discuss the advantages and disadvantages of each source of funding and analyze them numerically for both risk-neutral and...

The Effects of ITQ Management on Fishermen’s Welfare When the Processing Sector is Imperfectly Competitive AgEcon
McEvoy, David M.; Brandt, Sylvia J.; Lavoie, Nathalie; Anders, Sven M..
In this paper we use a general model of imperfect competition to predict welfare changes within an open-access fishery transitioning to individual transferable quota (ITQ) management. Although related research has explored the effects of market power in the harvesting sector on ITQ performance, none have considered the implications of an imperfectly competitive processing sector. This study addresses this question specifically in the context of the Atlantic herring fishery, although its implications are relevant to all fisheries with similar industry structure. Our results show that ITQs could have a negative impact on fishermen’s welfare when processors have market power and the cap on aggregate harvest is binding or becomes binding with the...

Electricity Restructuring and Regional Air Pollution AgEcon
Palmer, Karen L.; Burtraw, Dallas.
This paper investigates the regional air pollution effects that could result from new opportunities for inter-regional power transmission in the wake of more competitive electricity markets. The regional focus is important because of great regional variation in the vintage, efficiency and plant utilization rates of existing generating capacity, as well as differences in emission rates, cost of generation and electricity price. Increased competition in generation could open the door to changes in the regional profile of generation and emissions. We characterize the key determinant of changes in electricity generation and transmission as the relative cost of electricity among neighboring regions. In general, low cost regions are expected to export power...

Agricultural Production with Change and Uncertainty: A Temporal Case Study Simulation of Colorado Potato Beetle AgEcon
Heikkila, Jaakko; Peltola, Jukka.
Changes in climatic and policy environments combined with uncertainty related to stochastic environmental fluctuations make design of invasive pest policy challenging. These external changes are often exacerbated by changes in the species characteristics. We discuss facing local change and uncertainty when deciding ex ante on a specific policy strategy. Our empirical case deals with an invasive agricultural pest, Colorado potato beetle, and agricultural production in Finland. Invasions are modelled as temporally random events and stochasticity in key variables is built into the analysis. The viability of two specific policy options is evaluated given uncertainty and local change.

AGRICULTURAL PRICE VOLATILITY UNDER CLIMATE CHANGE: The Impact of Multiple Objectives on Commodity Prices AgEcon
Fuss, Sabine; Havlik, Petr; Szolgayova, Jana; Obersteiner, Michael; Schmid, Erwin.
Agricultural price volatility has moved to the forefront of research efforts and political discussion, where much work is already being undertaken with respect to the impact of fluctuations in input prices (e.g. fertilizer, feed and energy). In this paper we also want to take into account the impact of climate change on prices via increased volatility in crop yields. In addition, we analyze the impact of having multiple objectives competing for the land on which crops are grown. In particular, we want to address the concerns that have been voiced about biofuel targets and calls for prioritization of food security.

On the Choice of Cost and Effectiveness Indicators in the Context of the European Water Policy AgEcon
Sinabell, Franz; Schmid, Erwin.
The Water Framework Directive requires EU Member States to analyse economic impacts of the Directive's implementation. To reach a "good status", instruments have to be judged according to their cost-effectiveness. We evaluate costs and effects of measures to reduce nitrate emission of Austrian agriculture. Results are based on a model that integrates production decisions with stochastic environmental outcomes. The Directive's requirement to involve stakeholders may make it necessary to take a large number of indicators into consideration. We find that alternative calculations of the effectiveness criterion give different rankings of the most effective combination of measures.

Climate Change Policy AgEcon
Shogren, Jason F.; Toman, Michael.
Having risen from relative obscurity as few as ten years ago, climate change now looms large among environmental policy issues. Its scope is global; the potential environmental and economic impacts are ubiquitous; the potential restrictions on human choices touch the most basic goals of people in all nations; and the sheer scope of the potential response - a significant shift away from using fossil fuels as the primary energy source in the modern economy -is daunting. In this paper, we explore the economics of climate change policy. We examine the risks that climate change poses for society, the benefits of protection against the effects of climate change, and the costs of alternative protection policies. We organize our discussion around three broad...

The Price-Elasticity of Stumpage Sales from Federal Forests AgEcon
Ando, Amy Whritenour.
This paper explores the influence of the behavior of the Forest Service and Bureau of Land Management on effective public policy toward the national forests. It shows that fluctuations in stumpage sales from such forests have been large. Furthermore, those fluctuations could well have a significant impact on the price elasticity of harvest even with large stocks of uncut volume under contract. System analysis of harvest and sale patterns in nine regions during the period 1951-1992 shows that stumpage sales displayed little correlation with prices during the period; the positive price elasticity of harvest seems to have been induced largely by the behavior of logging firms. However, it finds a positive link between National Forest budgets and annual sales....

Auctioning Conservation Payments using Environmental Indices 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. For land retirement programs we conclude that, for the cases considered, the exogenous environmental performance does...

Output-Based Refunding of Emission Payments: Theory, Distribution of Costs, and International Experience AgEcon
Sterner, Thomas; Hoglund, Lena.
In this paper, we discuss the effect of refunding environmental charges. Taxes often are resisted by polluters because they imply both abatement and tax costs. We show that when charges are refunded, the incentives for abatement are essentially the same as for a tax, but the output reduction that often accompanies a tax scheme is forgone. We describe and examine the refund emissions payment (REP) scheme as a policy instrument for emissions abatement and compare it with taxes and permits with regard to allocative properties, distribution of costs, property rights, and, consequently, the politics of implementation. As an empirical example, the Swedish charge on nitrogen oxides is analyzed.

Bankruptcy Risk and the Performance of Tradable Permit Markets AgEcon
Stranlund, John K.; Zhang, Wei.
We study the impact of bankruptcy risk on markets for tradable environmental and natural resource permits. We find that firms that risk bankruptcy demand more permits than if they were financially secure. Consequently, bankruptcy risk in a competitive market for tradable property rights causes an inefficient distribution of individual choices among regulated firms. Moreover, the equilibrium distribution of permits is not independent of the initial distribution of permits. In fact, the inefficiency that is associated with bankruptcy risk is mitigated if financially insecure firms are given a larger share of the initial allocation of permits.

Delayed Participation of Developing Countries to Climate Agreements: Should Action in the EU and US be Postponed? AgEcon
Bosetti, Valentina; Carraro, Carlo; Tavoni, Massimo.
This paper analyses the cost implications for climate policy in developed countries if developing countries are unwilling to adopt measures to reduce their own GHG emissions. First, we assume that a 450 CO2 (550 CO2e) ppmv stabilisation target is to be achieved and that Non Annex1 (NA1) countries decide to delay their GHG emission reductions by 30 years. What would be the cost difference between this scenario and a case in which both developed and developing countries start reducing their emissions at the same time? Then, we look at a scenario in which the timing of developing countries’ participation is uncertain and again we compute the costs of climate policy in developed and developing countries. We find that delayed participation of NA1 countries has...

Governance and Environmental Policy Integration in Europe: What Can we learn from the EU Emission Trading Scheme? AgEcon
Sgobbi, Alessandra; Buchner, Barbara K.; Catenacci, Michela.
The European Union Emission Trading System (EU ETS) is a landmark environmental policy, representing the world's first large-scale greenhouse gas (GHG) trading program. The coexistence of state actors and top-down processes with stakeholders participation and flexible abatement strategies make the EU ETS a powerful instrument of cross sectoral integration of environmental concerns, which benefits from a high level of interaction among the actors involved and a significant degree of information exchange. However, the same peculiarities of the system make it difficult to identify a correspondence with a single mode of governance. The EU ETS shows characteristics of the decision making processes and institutions engaged, the tools and instruments used as...

Retroactive Liability and Future Risk: The Optimal Regulation of Underground Storage Tanks AgEcon
Boyd, James; Kunreuther, Howard.
The optimal design of environmental liability policy focuses on two primary policy issues: the cleanup of existing sources of pollution and the definition and enforcement of policies to promote prospectively efficient environmental risk reduction. Through the analysis of a policy toward a pervasive environmental risk -- leaking underground storage tanks - we analyze the effectiveness of an existing policy governing retroactive and prospective liability issues and suggest ways in which that policy can be improved. While we find some theoretical support for the public financing of UST cleanups, we also find the current system to be flawed in its implementation. In general, the paper argues that public financing of past pollution cleanup costs can lead to...

Assessing the Constraints and Opportunities for Private-Sector Participation in Activities Implemented Jointly: Two Case Studies from the US Initiative for Joint Implementation AgEcon
Powell, Mark R.; Lile, Ronald D.; Toman, Michael.
This paper assesses the constraints and opportunities for private-sector participation in Activities Implemented Jointly under the United Nations Framework Convention on Climate Change. After some initial background, the discussion turns to the United States Initiative on Joint Implementation (USIJI) - its objectives, proposal review and evaluation criteria, and a classification of project proposals by project type and stage of development. Two USIJI projects are developed as case studies. One case is an energy end use project that has gained formal acceptance and financing. The other case is an energy production project proposal that has not secured acceptance or financing. In both cases, transaction costs were substantial, and project proponents regarded...

European Climate Policy: Burden Sharing after 2012 AgEcon
Bode, Sven.
Regardless of whether or not the Kyoto Protocol enters into force, the EU may decide to set itself a long-term greenhouse gas emission target and thus to continue its leadership role in international climate policy. As for the first commitment period of the Kyoto Protocol, the EU may decide on a burden-sharing agreement as an integral part of such a long-term climate policy. Against this background I analyse three different options to distribute an overall budget of emission entitlements until 2042 among the member states of an enlarged EU. It is shown who wins and who loses with regard to compliance costs. As the member states' attitudes towards the different approaches are likely to depend on the relative attractiveness of the allocation options, a...

Implementation of Policy Instruments for Chlorinated Solvents: A Comparison of Design Standards, Bans, and Taxes to Phase Out Trichloroethylene AgEcon
Slunge, Daniel; Sterner, Thomas.
This paper studies the Swedish prohibition of the hazardous solvent Trichloroethylene (TCE). Sweden is alone in completely prohibiting its use. The ban has been at best a partial success and illustrates the dilemmas of policymaking. Use has declined but not stopped, largely because the decision to ban TCE was challenged in the courts. Recently, the EU Court of Justice decided in favor of Sweden's right to have a ban. This article analyzes abatement cost data to show that the cost of replacing TCE is low for most plants, although there appear to be a few firms for which it may be quite high. A cross-country comparison indicates that the Swedish ban was less effective than the very strict technical requirements in Germany or the tax used in Norway. A tax (or...
