An Econometric Analysis of Price Dynamics in the Presence of a Price Floor: The Case of American Cheese AgEcon
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.

Aquaculture and Fisheries Interactions: Implications for the Global Supply of Fish AgEcon
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....

Bacterial Resistance and the Optimal Use of Antibiotics AgEcon
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...

Collective Action for Watershed Management: Field Experiments in Colombia and Kenya AgEcon
Cardenas, Juan-Camilo; Rodriguez, Luz Angela; Johnson, Nancy L..
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...

Consumer Acceptance of Genetically Modified Foods in Taiwan: Is Positive Discount the Same as Negative Premium? AgEcon
Kaneko, Naoya; Chern, Wen S..
This paper finds Taiwanese consumers' willingness to pay a premium on the non-GM food differs from their willingness to accept a discount on the GM food. It further finds that the non-GM choosers are more committed to the non-GM food than the GM choosers to the GM food.

DEVELOPMENT OF A MARKET BENCHMARK PRICE FOR AGMAS PERFORMANCE EVALUATIONS AgEcon
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...

Economics of Cogongrass Control in Slash Pine Forests AgEcon
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.

Expected Utility Analysis of Stocker Cattle Ownership Versus Contract Grazing in the Southeast AgEcon
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.

Green Giving: An Analysis of Contributions to Major U.S. Environmental Groups AgEcon
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...

Hedonic Housing Prices and Agricultural Pollution: An Empirical Investigation on Semiparametric Models AgEcon
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.

IMPACTS OF THE URUGUAY ROUND TRADE AGREEMENT ON U.S. BEEF AND CATTLE PRICES AgEcon
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...

IMPORT DEMAND FOR DISAGGREGATED FRESH FRUITS IN JAPAN AgEcon
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...

Legal Families and Environmental Protection: Is there a Causal Relationship? AgEcon
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.
