For countries that could not benefit from the Green Revolution due to heterogeneous and unfavorable biophysical environments, agricultural biotechnology potentially provides a means of improving the quality and quantity of agricultural production. This paper analyses some of the major issues relating to the utilization of biotechnology in Kenya. A partial equilibrium trade model is applied to Kenya's corn market to study the potential of genetically modified maize that is tolerant to the Maize Streak Virus. The model accounts for home production and consumption; the positive results of the welfare estimation are disaggregated between consumers, large and small Kenyan corn farms.

THE IMPACTS OF MARKET POWER AND EXCHANGE RATES ON PRICES OF EUROPEAN UNION SOYBEAN IMPORTS..

A rational expectations competitive storage model is applied to the U.S. corn market to assess the aptness of this framework in explaining monthly price behavior in an actual commodity market. Relative to previous models, extensive realism is added to the model in terms of how production activities and storage costs are specified. By modeling convenience yield, "backwardation" in prices between crop years does not depend on the unrealistic assumption of zero ending stocks. Our model produces cash prices that are distributed with positive skewness and kurtosis, and mean and variance that increase over the storage season, consistent with the persistence and the occasional spikes observed in commodity prices. Futures prices are generated as conditional...

This study examines whether the EU, the world's largest importer, exercises market power over soybean imports. Results, based on 1975-2000 data, suggest that the EU has practiced price discrimination against imports from Argentina and Brazil. The evidence for the practice of pricing-to-market based on exchange rate changes is mixed.

Alfalfa Hay Quality and Alternative Pricing Systems

Price-quality relationships for alfalfa hay were analyzed by hedonic pricing models using 1996-2001 Wisconsin auction data. Individual nutrients included in the analysis all affected alfalfa price, with acid detergent fiber accounting for the largest impact. Alternative pricing models, based on an aggregate quality index or detailed quality information, were similar in their ability to predict price. However, disaggregating price predictions to account for differences in relative feed value (RFV) and crude protein (CP) indicate that both RFV and CP are important determinants of price and that aggregating the two into a quality index is not warranted.

Grain Marketing Strategies Within and Across Lifetimes

Income Enhancing and Risk Management Properties of Marketing Practices

To reconcile the discrepancy between the efficient market hypothesis and grain marketing recommendations by advisory services and extension programs, simulated prices from an efficient market are used to compare performance of marketing practices over the long run and in individual 40-year periods. We find that an efficient market can generate diverse price behavior within finite samples, allowing for strategies that are inferior on average to perform relatively better, as frequently as half of the time in an average 40-year lifetime. Lifetime returns of strategies show considerable overlap, suggesting extremely low confidence in recommendations made based on short samples.

A rational expectations storage model is used to simulate monthly corn prices, which are used to evaluate marketing strategies to manage price risk. The data are generated and analyzed in two formats: for long-run outcomes over 10,000 "years" of monthly prices and for 10,000 cases of 40-year "lifetimes." Three categories of strategies are analyzed: frequency of post-harvest cash sales, unconditional hedges, and conditional hedges. The comparisons are based on the simulated probability distributions of net returns. One conclusion is that diversifying cash sales, without hedging, is not an efficient means of risk management. Unhedged storage does not reduce risk and, on average, reduces returns. The analysis of the 40-year lifetimes demonstrates, however,...

Practioner's Abstract: Mad cow disease has caused two disruptions in European beef markets--first in the U.K. in 1996 following the announcement of a link to new variant Creutzfeldt-Jacob Disease in humans, and the second in late 2000 following the discovery of "homegrown" cases of the disease in Germany and Spain. In September 2001 the disease was discovered in Japan where it also resulted in an immediate and substantial reduction in beef demand. The disease has not been found in the U.S. but the current scope of detection efforts provides little assurance that it does not exist at a very low level. The U.S. has taken a number of precautionary measures to reduce both the risk of importing the disease and the risk of the disease spreading if it...

IMPLICATIONS OF DEFLATING COMMODITY PRICES FOR TIME-SERIES ANALYSIS

Palavras-chave: Livestock Production/Industries.

Ano: 2002

The choice of deflators of commodity prices can change the time-series properties of the original series. This is a specific application of the general phenomenon that various kinds of data transformations can create spurious cycles that did not exist in the original data. Different empirical models of expectations result from nominal and various deflated series that have distinct time-series properties, and these models, in turn, produce varying estimates of supply response and measures of price risk. The foregoing is illustrated by annual grain prices, monthly milk prices, and a milk supply analysis. Annual prices of corn and soybeans, for example, appear to vary around a constant mean, but when deflated by general price indexes such as the CPI, the...

Consumer Preferences for Attributes of Organic Processed Foods: The Case of Soymilk In the United States

Peterson, Hikaru Hanawa.

As increasingly more transactions occur away from open markets, the so-called "thin" market issues arise. This paper analyzes unpublished transaction data from Egg Clearinghouse, Inc. (ECI), a marginal marketplace for eggs that trades 4% of all eggs (80% of eggs available for open trading). Results suggest that marginalized markets can serve as an inventory adjustment mechanism while maintaining the role of price discovery as a check for non-market prices. At ECI, most firms both buy and sell regardless of operational types, participation is balanced across all types of firms in the industry, and sellers in general yield to buyers' preferred terms of trade.

Organic soymilk has been one of the fastest growing products in the organic food sector in recent years. Due to the shortage of domestically grown organic soybeans, outsourcing became a practice in the industry. It was estimated by some industry insiders that about 50% of organic soybeans consumed in the United States were imported from China (Cornucopia Institute, 2009). In 2009, the Organic Consumers Association called for a boycott of Silk products because it was reported that Silk, the dominant national brand in organic soymilk market, sourced organic soybeans from China and Brazil based on disputable standards. Under public pressure, Silk brand soymilk started to substitute U.S. grown non-genetically modified (GM) soybeans for imported organic...

Analysis of survey data indicates that Japanese consumers discount their willingness to pay for U.S. beef and pork relative to that of domestic products, but that the discounts have declined from 2006 to 2009. The discounts for U.S. products were greater than those imported from other countries in 2006, but the 2009 discounts were statistically indistinguishable across origins. Our findings also suggest than Japan is a receptive market for meat produced with GM-free feed and for meat products meeting full organic standards.

The Motivation for Organic Grain Farming in the United States: Profits, Lifestyle, or the Environment?

Peterson, Hikaru Hanawa; Barkley, Andrew P.; Chacon-Cascante, Adriana; Kastens, Terry L..

The objective of this research is to identify and quantify the motivations for organic grain farming in the United States. Survey data of US organic grain producers were used in regression models to find the statistical determinants of three motivations for organic grain production, including profit maximization, environmental stewardship, and an organic lifestyle. Results provide evidence that many organic grain producers had more than a single motivation and that younger farmers are more likely to be motivated by environmental and lifestyle goals than older farmers. Organic grain producers exhibited a diversity of motivations, including profit and stewardship.

Quality Perceptions and Willingness-to-Pay for Imported Rice in Japan

Peterson, Hikaru Hanawa; Yoshida, Kentaro.

Attitudes of Japanese consumers toward domestic and foreign varieties of rice were analyzed on the basis of a survey. We found that the current retail prices for imported rice are higher than the average consumers’ willingness-to-pay (WTP), whereas most domestic rice was priced below the average WTP. Unfamiliarity or negative perceptions of the safety and flavor of foreign rice lowered WTP substantially. The WTP for U.S. rice was limited more by negative perceptions of flavor than from concerns about food safety.

Wheat Variety Selection to Maximize Returns and Minimize Risk: An Application of Portfolio Theory

Barkley, Andrew P.; Peterson, Hikaru Hanawa; Shroyer, James.

This research shows that a portfolio of wheat varieties could enhance profitability and reduce risk over the selection of a single variety for Kansas wheat producers. Many Kansas wheat farmers select varieties solely based on published average yields. This study uses portfolio theory from business investment analysis to find the optimal, yield-maximizing and risk-minimizing combination of wheat varieties in Kansas.

To assess the impact of BSE in Japan, a Japanese meat demand system is estimated as a gradual switching Rotterdam model. The results, based on data from April 1994 to May 2002, suggest the structural transition took five months from its discovery. The scare affected both domestic and imported beef.
