Geographic Differences in the Relative Price of Healthy Foods AgEcon
Todd, Jessica E.; Leibtag, Ephraim S.; Penberthy, Corttney.
Although healthy foods can be affordable, if less healthy foods are cheaper, individuals may have an economic incentive to consume a less healthful diet. Using the Quarterly Food-at-Home Price Database, we explore whether a select set of healthy foods (whole grains, dark green vegetables, orange vegetables, whole fruit, skim and 1% milk, fruit juice, and bottled water) are more expensive than less healthy alternatives. We find that not all healthy foods are more expensive than less healthy alternatives; skim and 1% milk are less expensive than whole and 2% milk and bottled water is generally less expensive than carbonated nonalcoholic drinks. We also find considerable geographic variation in the relative price of healthy foods. This price variation may...

Asymmetric Price Transmission and Non-linear Adjustment in the Iranian Mutton Market AgEcon
Falsafian, Azadeh; Yazdani, Saeed; Moghaddasi, Reza.
This paper analyses the asymmetric price transmission and non-linear adjustment at the farm and retail levels in the Iran’s mutton market. We applied a multivariate threshold error correction mechanism for monthly price data. We tested the non-linear adjustment using sup-LR, sup-LM and sup-Wald tests. The results confirm the presence of non-linear cointegration relationship between the retail and farm prices. In short-run, the price transmission behavior reveals that reactions of both the retail and farm prices to positive and negative deviations from the long-run price spread are asymmetric. More specially, the retailers show more strong responses to the both positive and negative shocks imposed to the farmers.

The Impacts of Ethanol on the US Catfish Farm Sector AgEcon
Zheng, Hualu; Muhammad, Andrew; Herndon, Cary W., Jr..
In this study, we estimated catfish feed and farm price reduced form equations. Of particular importance was the impact of the recent increase in grain prices induced by ethanol production on feed cost and farm prices. This relationship was examined using an autoregressive distributed lag (ARDL) model. Results show that a 1% increase in corn prices caused a 0.134% and 0.263% increase in feed prices in the short- and long-run, respectively. Catfish farm prices increased by 0.106% (short-run) and 0.211% (long-run) given a 1% increase in feed prices. Between 2004 and 2008, corn prices increased from $2 to $6 per bushels. Taheripour and Tyner (2008) state that of the total increase, 25% was due to US ethanol subsidies and 75% was due to the increase in the...

The Marketing Performance of Illinois and Kansas Wheat Farmers AgEcon
Dietz, Sarah N.; Aulerich, Nicole M.; Irwin, Scott H.; Good, Darrel L..
The purpose of this paper is to investigate the marketing performance of wheat farmers in Illinois and Kansas over 1982-2004. The results show that farmer benchmark prices for wheat in Illinois and Kansas fall in the middle-third of the price range about half to three-quarters of the time. Consistent with previous studies, this refutes the contention that Illinois and Kansas wheat farmers routinely market the bulk of their wheat crop in the bottom portion of the price range. Tests of the average difference between farmer and market benchmark prices are sensitive to the market benchmark considered. Marketing performance of wheat farmers in Illinois and Kansas is about equal to the market if 24- or 20-month market benchmarks are used, is slightly above the...

Efficiency tests of agricultural commodity futures markets in China AgEcon
Wang, H. Holly; Ke, Bingfan.
The efficiency of the Chinese wheat and soybean futures markets is studied. Formal statistical tests were conducted based on Johansen’s cointegration approach for three different cashmarkets and six different futures forecasting horizons ranging from1 week to 4 months.The results suggest a long-termequilibrium relationship between the futures price and cash price for soybeans and weak short-term efficiency in the soybean futures market. The futures market for wheat is inefficient, which may be caused by overspeculation and government intervention.

VOLUME DE PRODUÇÃO, PREÇOS E A DECISÃO DE COMERCIALIZAÇÃO INFORMAL DO LEITE: UM ESTUDO NO ESTADO DO RIO DE JANEIRO AgEcon
Neto, Armando Chinelatto; Lima, Joao Eustaquio de.
The recent transformation in milk production was characterized by the reduction of the prices received by the producer and by the increase of the production and productivity. Facing this reality, this work has the objective to identify whether the option for informal commercialization of the milk was one of the alternatives for the small producers receiving better prices. It was used a logit model to measure the impact of production volume and price received over the probability of producers to opt to sell in informal markets. The results were compatible to what was expected, once the price received per milk litre affects positivelly and the volume production has a negative effect the probability of producers to sell his production at informal markets....

Effects of Maize Marketing and Trade Policy on Price Unpredictability in Zambia AgEcon
Chapoto, Antony; Jayne, Thomas S..
As events in the 2008/09 season have amply demonstrated, instability in staple food market remains a major problem in Zambia. A rise in world food price levels and instability, which is projected to occur in the near future according to several international institutes, will make it all more important for developing countries to consider the strengths and weaknesses of alternative approaches for buffering their domestic food systems from potential high volatility in world markets. These findings suggest that promoting more “rules based” approaches to...

MARKETING AND CROP INSURANCE COMBINED TO MANAGE RISK ON A CASS COUNTY REPRESENTATIVE FARM AgEcon
Clow, Aaron D.; Flaskerud, George K..
This study analyzed the effects that the use of crop insurance products and marketing alternatives had on the gross revenue per acre for an individual farm in Cass County. Crop insurance products and marketing strategies were analyzed individually to determine if they were effective in minimizing down side risk, and combined to determine if integration created synergies. A whole farm scenario analysis was run that included integrated strategies that implemented the same insurance coverage and marketing alternatives for each crop. Several general conclusions can be drawn for situations similar to the representative farm. When analyzed at the individual crop level, the use of crop insurance at the 65 percent level minimizes down side risk in wheat and corn,...

Substitution between domestic and imported orange juice and impacts of U.S. tariffs on prices and production AgEcon
Brown, Mark G.; Spreen, Thomas H.; Lee, Jonq-Ying.
A demand system model differentiating goods by product form and origin is developed to examine the impact of eliminating U.S. tariffs on orange-juice prices. An empirical analysis suggests a range of tariff impacts on prices depending on the degree of substitution between products. The model yielded similar results as alternative models when substitution was assumed to be relatively strong. In the long run, lower, without-tariff prices can be expected to lead to lower Florida orange planting and production levels. A sustained reduction in the U.S. OJ price of half the value of the FCOJ tariff is estimated to reduce orange planting levels by about 50% and orange production would declined by 24% by 2021-22.

Market Access by Smallholder Farmers in Malawi: Implications for Technology Adoption, Agricultural Productivity, and Crop Income AgEcon
Zeller, Manfred; Diagne, Aliou; Mataya, Charles.
In Malawi, maize is the major crop and food staple. Given limited off-farm employment opportunities, much-needed increases in household income for improving food security must come from gains in agricultural productivity through better technology and more profitable crops. In the past, agricultural policy promoted hybrid maize and, more recently, tobacco to increase smallholder income. This paper presents an analysis of what determines the adoption of these two crops and what kind of income effects follow from adoption. Apart from factor endowment and exposure to agroecological risks, differences in the household's access to financial and commodity markets significantly influence its cropping shares and farm income.

Trends in the Irish Beef Market During the 1990s - Identification and Analysis of Change Drivers AgEcon
O'Reilly, Seamus; McCarthy, Mary.
This paper provides a brief review of the Irish beef market during the 1990s. It sets out to identify the key factors influencing beef consumption during this period and reviews industry/ government response to consumer needs. A number of factors influencing beef consumption are identified, including: price, safety, eating quality and health. In addition to price competitiveness, industry/government response has focused on safety and quality systems. Safety emerged as an important factor during the 1990s and various traceability, quality assurance schemes and supply chain partnerships were established to reassure the consumer. By the end of the decade such systems are a pre-requisite to market entry and increasingly the focus is on using these systems to...

Payments under the Average Crop Revenue Program: Implications for Government Costs and Producer Preferences AgEcon
Cooper, Joseph C..
This paper develops a stochastic model for comparing payments to U.S. corn producers under the U.S. Senate’s Average Crop Revenue Program (ACR) versus payments under the price-based marketing loan benefit and countercyclical payment programs. Using this model, the paper examines the sensitivity of the density function for payments to changes in expected price levels. We also assess the impact of the choice of yield aggregation used in the ACR payment rate on the mean and variance of farm returns. We find that ACR payments lower the producer’s coefficient of variation of total revenue more than does the price-based support, although ACR may not raise mean revenue as much. While corn farmers in the heartland states might still prefer to receive the...

Weather Cycles, Production Yields and Georgia's Muscadine AgEcon
Raghunathan, Uthra; Wong, Jonathan; Escalante, Cesar L..
This paper looks at the relationship between weather, crop yield, and market price of muscadines using a dynamic panel data that spans from the 2000 to 2005 and across the state of Georgia. We use a Generalized Methods of Moments technique to estimate the impact of weather on the price of muscadines with the yield per acre as the instrumented variable. The results suggest that there is a relationship between the price and weather for muscadines, which provide important implications for the potential relevance of a weather derivative for muscadine production.
