Buyer and Seller Responses to an Adverse Food Safety Event: The Case of Frozen Salmon in Alberta. Leigh Maynard, Sayed Saghaian, and Megan Nickoloff. International Food and Agribusiness Management Review; 11, 1, (2008): 77-96.
Fish is a low-fat protein source high in omega-3 fatty acids, but in 2004 consumers also heard that farmed salmon had high levels of polychlorinated biphenyl (PCBs). This research evaluated how Canadian consumers and processors reacted to the confilicting health messages. Demand estimates and time-series analysis of 2001-2006 frozen meat scanner data in Alberta, Canada show a significant drop in salmon expenditure share following the PCB finding. The industry responded by launching low-priced wild salmon products, which contributed to significant demand expansion. The analysis illustrates how a food safety threat was averted and even served as a catalyst for growth.
Consumer Reaction to Beef Safety Scares. Sayed Saghaian and Michael Reed. International Food and Agribusiness Management Review, 10, 1, (2007): 18-35.
This study examines the impact of two beef safety scares on retail-level meat per capita consumption and prices in Japan. The objective is t investigate the Japanese consumer reactions to the news of FMD and BSE discoveries, as reflected in the quantitiy and price changes in the immediate neighborhood of each event. Better understanding of consumer reactions to beef safety scares helps the beef industry restore consumer confidence after food safety crises and provides opportunities for national-level production differentiation based on beef quality and traceability.
Safety Shocks and Dynamics of Vertical Price Adjustment: The Case of BSE Discovery in the U.S. Beef Sector. Sayed Saghaian. Agribusiness: An International Journal, 23, 3, (2007): 333-348.
This article addresses the dynamic impact of the 2003 Bovine Spongiform Encephalopathy discovery on the U.S. beef sector. Time series analysis and historical decomposition with weekly feedlot, wholesale, and retail beef price series is used to address the dynamics of price adjustment and causality along with U.S. beef marketing channel. The results show price transmission is bidirectional, determined through interaction between the different stages, and price adjustment is asymmetric with respect to both speed and magnitude. The results reveal a differential impact of the exogenous shock on producers and retailers, which leads to widening of price margins and points to imperfect preice transmission, specifically at the retail level, with consequences for the efficiency and equity of the marketing channel, [EconLit citations: Q11, Q13], © 2007 Wiley Periodicals, Inc.
The Effect of E. Coli 0157:H7, FMD and BSE on Japanese Retail Beef Prices: A Historical Decomposition. S. Saghaian, L. Maynard, and M. Reed. Agribusiness: An International Journal; 23, 1, (2007): 131-147.
This study examines Japanese retail price reactions to the 2001 bovine spongiform encephalaopaty (BSE) discovery, the 2000 outbreak of foot and mouth disease (FMD), and the 1996 E. coli food poisoning events. Historical decomposition of retail-level price series aids in explaining the behavior of beef prices in a neighborhood (period-by-period time interval) of the three events. This is based on an application of directed acyclic graphs, constructing orthogonal innovations to determine causal patterns behind contemporaneous innovations. The results show that the beef safety and animal health events had different negative impacts on Japanese retail beef prices, suggesting that consumers understood and differentiated among the health risks. The results provide incentives for beef producers and retailers to inform consumers proactively about ongoing beef and animal health measures. Understanding consumer reactio nto BSE, FMD and E. coli helps the beef industry restore consumer confidence after future crises, and provides policy makers a basis for countermeasures and compensations.

Monetary Policy Impacts on U.S. Livestock-Oriented Agricultural Prices. S. Saghaian and M. Reed. Progress in Economic Research; Volume 9. Nova Science Publishers, Inc., Hauppauge, NY. (2006): 45-62.
In this article we use vector error correction models to investigate the impacts of changing macroeconomic variables on individual agricultural commodity prices. Saghaian, Reed, and Marchant used some of these techniques for aggregate commodity prices. They found that aggregate commodity prices overshoot their long-run equilibrium when the money supply changes. Their model predicts that less-traded commodities and commodities whose demand is more interest rate sensitive will have higher degrees of overshooting. We also hypothesize in this article that product characteristics, market structure, and the biological nature of production influence overshooting and the time it takes individual agricultural commodity prices to meet their steady state. This article tests these hypotheses using individual grain and livestock prices, specifically examining whether grains (input) prices overshoot more than livestock (output) prices. We also study whether differing measures of monetary policy change the overshooting results and whether the use of real or nominal prices affects the empirical results. These results should help settle the questions about the appropriate definitions for these variables.
Measuring the Intensity of Competition in the Japanese Beef Market. M.R. Reed and S.H. Saghaian. Journal of Agricultural and Applied Economics; 36,1(April 2004):113-121.
A residual demand model for beef exports to Japan is specified and estimated. The objective is to estimate the extent of market power.
Integrating Marginal Cost into Pricing-to-Market Models for U.S. Agricultural Products. S.H. Saghaian and M.R. Reed. Canadian Association's Current Agriculture, Food and Resource Issues (CAFRI); 5(2004):187-203.
This article investigates the markup pricing behavior of U.S. exporters of agricultural products. Agricultural products studied are feed, flour, frozen potatoes, frozen orange juice, five categories of beef, five categories of pork, and two categories of chicken.
Demand for Quality Differentiated Beef in Japan. S.H. Saghaian and M.R. Reed. Agrarwirtschaft: German Journal of Agricultural Economics; 53,8 (2004):344-351.
In this article, we apply a model of vertical product differentiation to the Japanese beef market. We theoretically derive a system of consumer demand functions for quality-differentiated beef in Japan
