The Impact of Avian Influenza on Vertical Price Transmission in the Egyptian Poultry Sector AgEcon
Hassouneh, Islam; Radwan, Amr; Serra, Teresa; Gil, Jose Maria.
In recent years, health risks have received increasing attention among consumers and created interest in analysing the relationship between food scares, food consumption and market prices. One of the most relevant and recent food scares is the avian influenza that has had important effects not only on human and animal health, but also on the economy. We assess effects of avian influenza on price transmission along the Egyptian poultry marketing chain. Although Egypt has been one of the most affected countries by avian influenza, this article is the first attempt to understand this food scare’s impacts on Egyptian poultry markets. In doing so, a multivariate smooth transition vector error correction model (STVECM) is applied to monthly poultry price data....

Price transmission in the Spanish bovine sector: the BSE effect AgEcon
Hassouneh, Islam; Serra, Teresa; Gil, Jose Maria.
A regime-switching vector error correction model is applied to monthly price data to assess the impact of BSE outbreaks on price relationships and patterns of transmission among farm and retail markets for bovine in Spain. To evaluate the degree to which price transmission is affected by BSE food scares, a BSE food scare index is developed and used to determine regime-switching. Results suggest that BSE scares affect beef producers and retailers differently. Consumer prices are found to be weakly exogenous and not found to react to BSE scares, while producer prices conversely adjusted. The magnitude of the adjustment is found to depend on the magnitude of the BSE scare.

Non-parametric and Parametric Modeling of Biodiesel - Sunflower Oil - Crude Oil Price Relationships AgEcon
Hassouneh, Islam; Serra, Teresa; Gil, Jose Maria.
Multivariate local linear regression and parametric error correction models are applied to assess price linkages and price transmission patterns between food and energy prices in Spain. Weekly biodiesel, sunflower and crude oil prices observed from November 2006 to October 2010 are used in the empirical analysis. Results suggest the existence of a long-run equilibrium relationship between the three prices studied. Biodiesel is the only variable that adjusts to deviations from this long-run parity. Local linear regression techniques show that the speed of adjustment of biodiesel prices is higher when biodiesel is cheap than when it is expensive. Energy prices are also found to influence sunflower oil prices through the short-run price dynamics.

The impact of food scares on price transmission along the food marketing chain AgEcon
Hassouneh, Islam; Serra, Teresa; Gil, Jose Maria.
In this paper we show how regime-switching vector error correction models can be used to assess the effects of food scares on price transmission along the food marketing chain. Our empirical implementation focuses on the impacts of the BSE crisis on price relationships and patterns of transmission among farm and retail markets for bovine in Spain. Monthly prices are used over the 1996-2005 period. A BSE food scare index is developed in order to measure the scale of the food scare crisis. Results suggest that the crisis affects beef producers and retailers differently. While consumer prices are not found to adjust to the crisis, producer prices do, though only when the scale of the food scare reaches certain minimum levels.
