Resumen
Descripción
This article examines food price volatility in Greece and how it is affected by short-run
deviations between food prices and macroeconomic factors. The methodology follows the GARCH and GARCH-X models. The results show that there exists a positive effect between the deviations and food price volatility. The results are highly important for producers and consumers because higher volatility augments the uncertainty in the food markets. Once the participants receive a signal that the food market is volatile, this might lead them to ask for increased government intervention in the allocation of investment resources and this could reduce overall welfare.
