Are Compact Cities Environmentally (and Socially) Desirable? AgEcon
Gaigne, Carl; Riou, Stephane; Thisse, Jacques-Francois.
There is a wide consensus among international institutions and national governments in favor of compact (i.e. densely populated) cities as a way to improve the ecological performance of the transport system. Indeed, when both the intercity and intra-urban distributions of activities are given, a higher population density makes cities more environmentally friendly as the average commuting length is reduced. However, when we account for the possible relocation of activities within and between cities in response to a higher population density, the latter may cease to hold. Because changes in population density affect land rents and wages, firms and workers re-optimize and choose new locations. We show that this may reshape the urban system in a way that...

Modelling the Impact of Compulsory FMD Insurance AgEcon
Jansson, Torbjorn; Norell, Bo; Rabinowicz, Ewa.
This paper compares two ways of financing the combating of Foot and Mouth Disease (FMD) in the EU and uses a simulation model to determine the welfare and production implications of the two systems. The two systems analysed are (i) financing by the tax payers, resembling the system currently in place, and (ii) a compulsory insurance scheme where all costs are converted into regionally differentiated insurance premiums that are paid by the producers. The analysis indicates that welfare gains may be realised by shifting from the former to the latter financing system.

Sustainable Decision-making: The State of the Art from an Economics Perspective AgEcon
Toman, Michael.
Government, corporate and other decision makers are more and more often being urged to 'act sustainably' and to pursue policy paths toward 'sustainable development.' However, application of these concepts is hampered by serious interdisciplinary disagreements about the interactions of humans with their environment. Moreover, reducing disagreements about sustainability cannot be achieved solely through an improvement in scientific knowledge. These observations lead me to express skepticism about the capacity of any more or less mechanistic rule, economic, scientific or otherwise, to provide definitive and reliable answers about sustainable policies or conduct. However, there are processes and procedures that can help guide decision-making. I underscore the...

What's the Rate? Disentangling the Weitzman and the Gollier Effect AgEcon
Traeger, Christian P..
The uncertainty of future economic development affects the term structure of discount rates and, thus, the intertemporal weights that are to be used in cost benefit analysis. The U.K. and France have recently adopted a falling term structure to incorporate uncertainty and the U.S. is considering a similar step. A series of publications discusses the following concern: A seemingly analogous argument used to justify falling discount rates can also be used to justify increasing discount rates. We show that increasing and decreasing discount rates mean different things, can coexist, are created by different channels through which risk affects evaluation, and have the same qualitative effect of making long-term payoffs more attractive.

Using Environmental Benefit-Cost Analysis to Improve Government Performance AgEcon
Farrow, Scott; Toman, Michael.
In this paper we first describe the legal and administrative basis of mandates that variously require and eschew economic measures for environmental management. We then summarize the steps involved in benefit-cost analysis and what can and cannot be accomplished with such information. Our basic conclusion is that while the approach is not perfect, benefit-cost analysis has a solid methodological footing and provides a valuable performance measure for an important governmental function, improving the well-being of society. However, benefit-cost analysis requires analytical judgements which, if done poorly, can obfuscate an issue or worse, provide a refuge for scoundrels in the policy debate. We conclude the article with specific suggestions for both the...

Prices vs. Quantities in Monopolistic Competition AgEcon
Vetter, Henrik.
In perfectly competitive markets taxes and quotas are fully equivalent measures for environmental protection. Based on this regulators' revealed preferences for quotas over that of fees finds its explanation in the procedures and spirits of political decision making. This paper offers another explanation: Ordinary welfare economic considerations make a quota preferable to a tax when regulating polluting firms in monopolistically competitive markets.

Benefit Transfer as Preference Calibration AgEcon
Smith, V. Kerry; van Houtven, George; Pattanayak, Subhrendu K..
This paper proposes and illustrates the use of a new approach to benefit transfer for the non-market valuation of environmental resources. It treats transfer as an identification problem that requires assessing whether available benefit estimates permit the parameters of a preference function to be identified. The transfer method proposed uses these identifying restrictions to calibrate preference parameters and bases the benefit estimates on that preference function. The approach is illustrated using travel cost, hedonic and contingent valuation estimates, as well as combinations of estimates. It has three potential advantages over conventional practice: (1) it allows multiple, potentially overlapping estimates of the benefits of an improvement in...

Do Environmental Services Buyers Prefer Differentiated Rates? A Case Study from the Colombian Andes AgEcon
Moreno-Sanchez, Rocio del Pilar; Maldonado, Jorge Higinio; Wunder, Sven; Borda, Carlos Andres.
Flat user fees in payment for environmental services (PES) schemes promote administrative ease, and are sometimes perceived as egalitarian. However, when environmental service (ES) buyers are heterogeneous in their income and water consumption levels, this may not be optimal, as total payments become too low and services are under-supplied. This paper identifies ES buyer preferences and estimates their willingness to pay (WTP) differentiated fees in an ongoing PES initiative in an Andean watershed in Colombia. Small, flat user payments have recently been introduced to implement incipient watershed protection upstream. Environmental service users fall into two highly heterogeneous categories: smallholder peasants and owners of recreational houses. We...

BLUNT TO SHARPENED RAZOR: INCREMENTAL REFORM AND DISTORTIONS IN THE PRODUCT AND CAPITAL MARKETS IN CHINA AgEcon
Zhang, Xiaobo; Tan, Kong-Yam.
A key objective of China's reform program was to reduce distortions in the economic system and enhance growth. However, when implemented in incremental and partial ways, local governments or individuals have chance to capture rents inherent in the reform process. Young (2000) warned that the rent-seeking behavior might lead to increasing market fragmentation. Empirical studies have since shown that this did not happen in the product markets. In this paper we argue that as rents from the product markets were squeezed out during the reform process, rent-seeking behavior shifted to the factor markets, especially the capital and land markets. The reform process now needs to be deepened to ensure that the factor markets also become more integrated and efficient.

Southeastern Peanut-Production Cost Efficiency Under the Quota System: Implications for the Farm-Level Impacts of the 2002 Farm Act AgEcon
Nadolnyak, Denis A.; Fletcher, Stanley M.; Hartarska, Valentina M..
In the article, stochastic frontier analysis of peanut-production efficiency in the Southeastern region of the United States is conducted with a view of assessing the likely farm-level impacts of the 2002 Farm Act. Results indicate that , although quota ownership did not significantly impact inefficiency, it is likely that limitations on the quota’s transferability to areas with better growing conditions were a significant cause of inefficiency. The acreage shifts and improved yields following the passage of the 2002 Farm Act support this conclusion. Certain farm characteristics, such as farm size and operator’s education and age, were also important for efficiency.

Regulatory Takings and the Diminution of Value: An Empirical Analysis of Takings and Givings AgEcon
Truesdell, Marie K.; Bergstrom, John C.; Dorfman, Jeffrey H..
A hedonic model is used to measure the change in value of residential lots in Rockport, Texas, resulting from Section 404 of the U.S. Clean Water Act. Results show that average lot values initially decreased, went though a six-year adjustment period, and then stabilized on a higher price path resulting in a positive net effect on average lot values throughout the Rockport area (with the exception of a particular subdivision). The results indicate that Section 404 generated both regulatory "takings" and "givings," suggesting that both effects should be considered when assessing the benefits and costs of regulatory events and compensation claims.

ECONOMIC IMPACTS OF BANNING SUBTHERAPEUTIC USE OF ANTIBIOTICS IN SWINE PRODUCTION AgEcon
Brorsen, B. Wade; Lehenbauer, Terry; Ji, Dasheng; Connor, Joseph.
Public health officials and physicians are concerned about possible development of bacterial resistance and potential effects on human health that may be related to the use of antimicrobial agents in livestock feed. The focus of this research is aimed at determining the economic effects that subtherapeutic bans of antimicrobials would have on both swine producers and consumers. The results show that a ban on growth promotants for swine would be costly, totaling $242.5 million annually, with swine producers sharing the larger portion in the short run and consumers sharing the larger portion in the long run.

Output-Based Allocations of Emissions Permits: Efficiency and Distributional Effects in a General Equilibrium Setting with Taxes and Trade AgEcon
Fischer, Carolyn; Fox, Alan K..
The choice of mechanism for allocating tradable emissions permits has important efficiency and distributional effects when tax and trade distortions are considered. We present different rules for allocating carbon allowances within sectors (lump-sum grandfathering, output-based allocation [OBA], and auctioning) and among sectors (historical emissions and value-added shares). Using a partial equilibrium model, we explore how OBA mitigates price increases, limits incentives for conservation in favor of lowering energy intensity, and changes relative output prices among sectors. We then use a computable general equilibrium model from the Global Trade Analysis Project, modified to incorporate a labor/leisure choice, to compare overall mechanism performance....

COST EFFICIENCY OF CATFISH FARMS IN CHICOT COUNTY, ARKANSAS: THE IMPACT OF EXTENSION SERVICES AgEcon
Engle, Carole R.; Kaliba, Aloyce R..
Cost efficiency measures of a sample of catfish farms in Chicot County, Arkansas are estimated using a data envelopment analysis technique. A measure of overall efficiency is used to determine operator's characteristics, farm practices, and institutional support services that are likely to lead to higher farm level cost efficiency. Results indicate that live catfish production could increase by 55% using the same level of inputs if all farms were operating at the minimum average cost curve. Higher feeding rate and availability of extension services were associated with increased cost efficiency. Higher stocking density affected overall efficiency negatively. The marginal value of extension contacts in Chicot County was estimated to be $2988. This study...

Is There a Rationale for Rebating Environmental Levies? AgEcon
Bernard, Alain; Fischer, Carolyn; Vielle, Marc.
Political pressure often exists for rebating environmental levies, particularly when incomplete regulatory coverage allegedly creates an“"unlevel playing field" with other, unregulated firms or industries. This paper assesses the conditions under which rebating environmental levies is justified for the regulated sector. It combines a theoretical approach based on second-best modeling with numerical simulations aimed at determining the most sensitive parameters. We find that if an adequate tax on production can be levied in the unregulated sector, no rebate is justified for the regulated sector. Moreover, even in the case of constrained taxation in the unregulated sector, a tax rebate or a subsidy in the regulated sector is not necessarily a...
