In this paper we extend the traditional GARCH(1,1) model by including a functional trend term in the conditional volatility of a time series. We derive the main properties of the model and apply it to all agricultural commodities in the Mexican CPI basket, as well as to the international prices...

This study aims to improve our understanding of the extent and speed of the transmission of international cereal prices to local markets in developing countries. We analyse two samples of price transmission (PT) estimates, one extracted from a comprehensive literature sample of 31 published...

This study examines the linkages between energy price and food prices over the period 2000-2016 by using a Panel-VAR model in the case of eight Asian economies, namely Bangladesh, the PRC, Indonesia, India, Japan, Sri Lanka, Thailand, and Viet Nam. Our results confirm that energy price (oil...

Motivated by repeated price spikes and crashes over the last decade, we investigate whether the rapidly growing market shares of futures speculators have destabilized commodity spot prices. We approximate conditional volatility and regress it on expected and unexpected speculative open interest....

This study explores the link between proximity and price cointegration between two markets, where proximity is captured with variables for geographical, political and cultural distance. Linear and threshold cointegration is tested for a set of 756 rice market pairs in 6 West African countries,...
