The behaviour of food relative prices: An analysis across the European Countries AgEcon
Gutierrez, Luciano; Brasili, Cristina; Fanfani, Roberto.
In this paper we analyze the behavior of relative food prices for a set of 24 European countries observed during the period 1996.1 - 2007.7. Using new methods for analyzing nonstationary panels, we are able to show that relative food prices have a common component which accounts for a large share of their variance. We show that this component has had a greater effects on the group of countries that adopt the Euro. We also find that countries in the Euro area are more market integrated, i.e. food prices tend to converge, than countries that have not adopted the Euro. Finally, we report that the half-live of a shock to relative food prices varies depending on the product, and that the adjustment is generally faster, on average about 10 months, than those...

Common Trends, Common Cycles, and Price Relationships in the International Fiber Market AgEcon
Fadiga, Mohamadou L.; Misra, Sukant K..
A multivariate unobserved component model was applied to identify common movements among cotton, wool, rayon, and polyester world prices. Two common stochastic trends and cycles govern the stochastic behaviors of price fluctuations in the world fiber market. These unobserved components have important implications as they can help in the design of more efficient commodity programs to smooth terms of trade shocks, especially in developing countries. The study found the effect of inventory adjustments on world cotton price is diminishing, which indicates that speculative behaviors in the world fiber market are less prevalent than previously thought.
