Uncertainty in Individuals' Preferences for Non-commodity Outputs Provided by Rural Development Programs (RDPs): A Contingent Valuation Approach
Provedor de dados: 31
Autores: Dominguez-Torreiro,   Marcos; Solino,   Mario.
Rural development programs (RDPs) are currently envisaged as a means to foster the provision of a broad range of non-commodity outputs emanating from multifunctional rural environments. This paper presents a Contingent Valuation survey that analyses individuals’ perceptions of and willingness to pay (WTP) for the implementation of a RDP in Cantabria, Spain. Uncertainty in individuals’ preferences is explicitly acknowledged and introduced into our analytical framework. For that purpose, a comparison is made between the open-ended (OE) and the multiple bounded uncertainty (MBU) elicitation formats. According to our behavioural model estimates, the expectation of a positive welfare change for both rural and urban dwellers constitutes a sound argument in...

Social Norms and Behavior in the Local Commons Through the Lens of Field Experiments
Provedor de dados: 31
Autores: Cardenas,   Juan-Camilo.
Behavior in the local commons is usually embedded in a context of regulations and social norms that the group of users face. Such norms and rules affect how individuals value material and non-material incentives and therefore determine their decision to cooperate or over extract the resources from the common-pool. This paper discusses the importance of social norms in shaping behavior in the commons through the lens of experiments, and in particular experiments conducted in the field with people that usually face these social dilemmas in their daily life. Through a large sample of experimental sessions with around one thousand people between villagers and students, I test some hypothesis about behavior in the commons when regulations and social norms...

Short-Run Demand Relationships in the U.S. Fats and Oils Complex
Provedor de dados: 31
Autores: Goodwin,   Barry K.; Harper,   Daniel C.; Schnepf,   Randall D.
Fats and oils play a prominent role in U.S. dietary patterns.  Recent concerns over the negative health consequences associated with fats and oils have led many to suspect structural change in demand conditions.  Our analysis considers short run (monthly) demand relationships for edible fats and oils.  In that monthly quantities of fats and oils are likely to be relatively fixed, an inverse almost ideal demand system specification is used.  A smooth transition function is used to model a switching inverse almost ideal demand system that assesses short-run demand conditions for edible fats and oils in the United States.  The results suggest that short-run demand conditions for fats and oils experienced a gradual structural shift that began in the late 1980s...

Green Giving: An Analysis of Contributions to Major U.S. Environmental Groups
Provedor de dados: 31
Autores: Richer,   Jerrell.
Data are compiled from the tax records of 29 major environmental organizations for the period 1980-1994 to identify factors that influence voluntary contributions. I examine the effects of organizational characteristics, such as fundraising expenditures and alternative sources of revenue, along with the impact of general economic conditions and the political climate. I find that government grants to the organizations had a positive and statistically significant impact on voluntary contributions rather than a crowding out effect. Contributions were price inelastic, where the price is defined as the effective cost to the donor of achieving a one-dollar increase in the provision of program services. Resources devoted to fundraising had a strong and positive...

Autores: Schmitz,   Troy G.; Seale,   James L., Jr.
Using annual Japanese fresh fruit import data from 1971 to 1997, this study analyzes the import patterns of Japan's seven most popular fresh fruits by implementing and testing a general differential dmand system that nests four alternative import demand specifications.  When tested against the general system using the five-good case (bananas, grapefutis, oranges, and lemons and aggregating pineapples, berries, and grapes), the analysis rejects the Almost Ideal Demand System and National Bureau of Research specifications but does not reject Rotterdam and Central Bureau of Statistics models.  When estimated using the six-good case (bananas, grapefuits, oranges, lemons, and pineapples and aggregating berries and grapes), the analysis rejects all...

Philippine Rice and Rural Poverty: An Impact Analysis of Market Reform Using CGE
Provedor de dados: 31
Autores: Cororaton,   Caesar B.
This paper looks at how Philippine trade reform which consists of tariff reduction and elimination of quantitative restrictions (QR) on rice imports will affect poverty within two world trade scenarios: Doha and free world trade. The impact of Doha is very small and generates biased effects against agriculture. The impact of Philippine trade reform within the Doha agenda magnifies this biased effect, making rural households worse-off compared to urban households. However, eliminating rice QR generates a set of effects where consumer price reduction dominates nominal income decline. Thus, real income improves and poverty declines across household groups, but the net effects are lower in rural than in urban households. The impact of a free world trade...

DEVELOPMENT OF A MARKET BENCHMARK PRICE FOR AGMAS PERFORMANCE EVALUATIONS
Provedor de dados: 31
Autores: Good,   Darrel L.; Irwin,   Scott H.; Jackson,   Thomas E.
The purpose of this research report is to identify the appropriate market benchmark price to use to evaluate the pricing performance of market advisory services that are included in the annual AgMAS pricing performance evaluations. Five desirable properties of market benchmark prices are identified. Three potential specifications of the market benchmark price are considered: the average price received by Illinois farmers, the harvest cash price, and the average cash price over a two-year crop marketing window. The average cash price meets all of the desired properties, except that it would not be easily implementable by producers. It can be shown, though, that the price realized via a more manageable strategy of "spreading" sales during the marketing...

Which Broiler Part is the Best Part?
Provedor de dados: 31
Autores: Goodwin,   Harold L., Jr.; McKenzie,   Andrew M.; Djunaidi,   Harjanto.
Predominance of production and marketing contracts in the broiler industry suggests a traditional analysis of price relationships might no longer be appropriate.  In this study, markets for broiler cuts are defined as spatial.  Results of a vector autoregressive regression analysis of monthly USDA data from 1987 to 2000 verify the price relationship between white meat and whole broiler prices.  Price shocks in the boneless skinless breast market have a greater effect than dark meat shocks, suggesting this market is most important in price transmission.  These results will assist industry participants to form more effective marketing and pricing strategies, thus adding efficiency to the market.

An Econometric Analysis of Price Dynamics in the Presence of a Price Floor:  The Case of American Cheese
Provedor de dados: 31
Autores: Chavas,   Jean-Paul; Kim,   Kwansoo.
In this paper, we present an econometric analysis for the effects of a price floor on price dynamics and price volatility. A price floor (implemented as a part of government pricing policy) provides a censoring mechanism for price determination. We specify and estimate a dynamic Tobit model under time-varying volatility.  The model is applied to analyze the effects of a price support program on price dynamics and price volatility in the U.S. American cheese market.  The econometric analysis provides useful insights on price dynamics in the presence of a government-determined price floor.

Autores: Bertoli,   Roberto; Zuluaf,   Carl R.; Irwin,   Scott H.; Jackson,   Thomas E.; Good,   Darrel L.
The 1995 marketing styles for the 25 market advisory service programs included in the AgMAS Project were developed in two steps. The first step was the construction of a detailed "menu" of the tools and strategies used by each of the advisory programs in marketing corn and soybeans. The menu describes the type of pricing tool, frequency of transactions, and magnitude of transactions. The second step was the development of a daily index of the net amount sold by each market advisory program. To construct such an index, the various futures, options, and cash positions recommended for a program on a given day were weighted by the respective position "delta." When the daily values of the index were plotted for the entire marketing period, the marketing...

THE COMPLEX DYNAMICS OF SMALLHOLDER TECHNOLOGY ADOPTION:  THE CASE OF SRI IN MADAGASCAR
Provedor de dados: 31
Autores: Moser,   Christine M.; Barrett,   Christopher B.
This paper explores the dynamics of smallholder technology adoption, with particular reference to a high-yielding, low-external input rice production method in Madagascar.  We present a simple model of technology adoption by farm households in an environment of incomplete financial and land markets.  We then use a probit model and a symmetrically trimmed least squares estimation of a dynamic Tobit model to analyze the decisions to adopt, expand and disadopt the method.  We find that seasonal liquidity constraints discourage adoption by poorer farmers.  Learning effects – both from extension agents and from other farmers– exert significant influence over adoption decisions.

Bacterial Resistance and the Optimal Use of Antibiotics
Provedor de dados: 31
Autores: Laxminarayan,   Ramanan.
The increasing resistance of harmful biological organisms (bacteria, parasites, and pests) to selection pressure from the widespread use of control agents such as antibiotics, antimalarials, and pesticides is a serious problem in both medicine and agriculture. Modeling resistance-or, conversely, the effectiveness of these control agents as a biological resource-yields insights into how these agents should be optimally managed to maximize their economic benefit to society. This paper uses a model of evolution of bacterial resistance to antibiotics-in which resistance places an evolutionary disadvantage on the resistant organism-to develop a simple sequential algorithm of optimal antibiotic use. Although the solution to this problem follows the...

U.S. BEEF AND CATTLE IMPORTS AND EXPORTS: DATA ISSUES AND IMPACTS ON CATTLE PRICES
Provedor de dados: 31
Autores: Brester,   Gary W.; Marsh,   John M.
U.S. participation in trade liberalization agreements with Canada and Mexico through the Canada–U.S. Free Trade Agreement (CFTA) and the North American Free Trade Agreement (NAFTA) has generated intense debates in agricultural sectors about the benefits and costs of those agreements. The CFTA and NAFTA mandate that live cattle and beef trade among Canada, Mexico, and the United States be based upon competitive factors and include legal safeguards to deal with arbitrary trade restrictions. Nominal and real U.S. fed and feeder cattle prices declined throughout the 1990s. Over the same period, the total U.S. beef supply increased from 25 billion pounds to 28.5 billion pounds. Imports (both beef and beef obtained from live cattle) accounted for almost 0.5...

Hedonic Housing Prices and Agricultural Pollution: An Empirical Investigation on Semiparametric Models
Provedor de dados: 31
Autores: Bontemps,   Christophe; Simioni,   Michel; Surry,   Yves R.
The objective of this paper is to assess the impact on property values of agricultural pollution using alternative semiparametric hedonic price models.  The proposed model specifications are made up of two parts: a partially linear component for house characteristics and a non (semi) parametric form to represent the non linear influence of agricultural pollution.  A general-to-specific search procedure is adopted to select the best model specification.  An application of theses parametric models to rural townships indicates that pollution resulting on livestock operations have a significant nonlinear impact on house prices.

Expected Utility Analysis of Stocker Cattle Ownership Versus Contract Grazing in the Southeast
Provedor de dados: 31
Autores: Anderson,   John D.; Lacy,   Curt; Forrest,   Charlie S.; Little,   Randall D.
Stocker cattle ownership is compared to contract grazing using stochastic simulation.  Returns are evaluated for both cattle owners and caretakers in contract grazing agreements.  For caretakers, contract grazing is significantly less risky than cattle ownership.  Slightly to moderately risk-averse caretakers could be expected to prefer some type of contract grazing to direct ownership of cattle.  For cattle owners, contracting reduces risk only slightly while significantly reducing expected returns.

Managing the growing quantity of used electronic equipment poses challenges for waste management officials. In this paper, we focus on a large component of the electronic waste stream— computer monitors-and the disposal concerns associated with the lead embodied in cathode ray tubes (CRTs) used in most monitors. We develop a policy simulation model of consumers- disposal options based on the costs of these options and their associated environmental impacts. For the stock of monitors disposed of in the United States in 1998, our preliminary findings suggest that bans on some disposal options would increase disposal costs from about $1 per monitor to between $3 and $20 per monitor. Policies to promote a modest amount of recycling of monitor parts, including...

This paper is a guide for citizens, scientists, resource managers, and policy makers, who are interested in understanding the economic and social value of marine protected areas (MPAs). We discuss the potential benefits and costs associated with MPAs as a means of illustrating the economic and social tradeoffs inherent in implementation decisions. In general, the effectiveness of a protected area depends on a complex set of interactions between biological, economic, and institutional factors. While MPAs might provide protection for critical habitats and cultural heritage sites and, in some cases, conserve biodiversity, as a tool to enhance fishery management their impact is less certain. The uncertainty stems from the fact that MPAs only treat the symptoms...

Willingness to Pay for Genetically Modified Oil, Cornflakes, and Salmon: Evidence from a U.S. Telephone Survey
Provedor de dados: 31
Autores: Kaneko,   Naoya; Chern,   Wen S.
This paper reports results from a U.S. national telephone survey on genetically modified foods (vegetable oil, cornflakes, and salmon).  The survey featured a contingent valuation in which respondents chose between the GM and non-GM alternatives with an option of indifference.  The binomial and multinomial logit models yielded estimated willingness to pay (WTP) to avoid the GM alternatives.  Respondents were willing to pay 20.9%, 14.8%, 28.4%, and 29.7% of the base prices to avoid GM vegetable oil, GM cornflakes, GM-fed salmon, and GM salmon, respectively.  The inclusion of indifference option could increase the sample size and moderate the mean WTP.

Aquaculture and Fisheries Interactions: Implications for the Global Supply of Fish
Provedor de dados: 31
Autores: Arnason,   Ragnar.
Aquaculture, or more generally fish farming, and fisheries interact in several different ways.  First, many types of fish farming require fish products as inputs, mostly for feeding purposes.  Second, farmed fish and wild fish products compete in fish markets with consequences for both the industry and, of course, consumers.  Third, fish farming generates various types of polluting agents that may affect wild fish stocks and their habitat.  Several other interactions exist.  This paper is primarily concerned with the implications of the first of these interactions, namely the input relationships, for the overall supply of fish products in the future.  To the extent that the fish farming industry demands wild fish products such as fish meal, fish oil, etc....

Autores: Alavalapati,   Janaki R.R.; Jose,   Shibu; Stainback,   G. Andrew; Matta,   Jagannadha R.; Carter,   Douglas R.
Cogonagrass  (Imperata Cylindrica), an invasive weed, is a threat to slash pine forests.  Using a dynamic optimization model, we estimated the impact of cogongrass on the profitability of slash pine forestry under four scenarios:  no threat of cogongrass infestation; infestation is uncertain, and no control measures are taken; infestation is uncertain, but control measures are undertaken by one landowner but not the neighbors; and infestation is uncertain, and control measures are undertaken by everyone.  Results indicate that annual net returns per acre under each scenario, respectively, are $25.30, $16.97, $13.89, and $17.38. Results suggest fostering a cooperative behavior among landowners is desirable.

Measuring Ecosystem Service Benefits: The Use of Landscape Analysis to Evaluate Environmental Trades and Compensation
Provedor de dados: 31
Autores: Boyd,   James; Wainger,   Lisa.
Ecosystem compensation and exchange programs require benefit analysis in order to guarantee that compensation or trades preserve the social benefits lost when ecosystems are destroyed or degraded. This study derives, applies, and critiques a set of ecosystem benefit indicators (EBIs). Organized around the concept of ecosystem services and basic valuation principles we show how GIS mappings of the physical and social landscape can improve understanding of the ecosystem benefits arising from specific ecosystems. The indicator system focuses on landscape factors that limit or enhance an ecosystem's ability to provide services and that limit or enhance the expected value of those services. The analysis yields an organized, descriptive, and numerical depiction...

The dilemma of collective action around water use and management involves solving both the problems of provision and appropriation. Cooperation in the provision can be affected by the rival nature of the appropriation and the asymmetries in the access. We report two field experiments conducted in Colombia and Kenya. The Irrigation Game was used to explore the provision and appropriation decisions under asymmetric or sequential appropriation, complemented with a Voluntary Contribution Mechanism experiment which looks at provision decisions under symmetric appropriation. The overall results were consistent with the patterns of previous studies: the zero contribution hypotheses is rejected whereas the most effective institution to increase cooperation was...

IMPACTS OF THE URUGUAY ROUND TRADE AGREEMENT ON U.S. BEEF AND CATTLE PRICES
Provedor de dados: 31
Autores: Brester,   Gary W.; Marsh,   John M.
The Uruguay Round trade negotiations completed in April 1994 reduced beef trade barriers. Trade barriers for beef products have historically been significant. The Uruguay Round essentially converts many nontariff barriers (quotas) to tariffs (tariffication), includes safeguards for import surges, establishes minimum access commitments, reduces domestic subsidy supports, and provides special tariff allowances for developing countries. These provisions, commensurate with a growing world demand for animal source proteins, will likely increase U.S. fed beef exports and ground beef imports. The United States is a major world producer as well as exporter of beef. In 1996, the United States represented 35 percent of world beef production (ranked first) and 28...

Legal Families and Environmental Protection: Is there  a Causal Relationship?
Provedor de dados: 31
Autores: Di Vita,   Giuseppe.
In this paper we build up the analysis of La Porta et al. (1998), to investigate the importance of legal families in explaining the variations in pollution emissions in different countries. The main intuition behind our analysis is that the nations in which the rights of shareholders are more protected, promote real and financial investment; this increases the speed at which the per-capita income corresponding to the declining branch of the Environmental Kutznets Curve (EKC) is achieved. In econometrics different regression analyses were performed using as dependent variables three different kinds of pollutants (CO2, fine suspended particulates and waste), including as an explanation some financial variables never before considered in this kind of study.
