(Punjab Agricultural University, Ludhiana, 2011) Upma
The present study “Study Of Volatility And Price Interrelationship Among Selected Edible Oils In India” was undertaken to understand price fluctuations in edible oils and also to understand price interdependence. The secondary data of daily prices of Crude Palm oil, Mentha oil and Refined soya oil was obtained from Multi Commodity Exchange. It was found that on monthly basis, minimum coefficient of variation was 0.74 % (April 2010), 0.65 % (Sept 2009), 0.56 % (March 2006) for Crude palm oil, Mentha oil and Refined soya oil respectively. Maximum coefficient of variation on monthly basis was found to be 7.07 % (April 2009), 20.23 % (Feb 2009), 5.84 % (March 2008) for Crude palm oil, Mentha oil and Refined soya oil respectively. Annual coefficient of variation was highest of 27 % in 2008, 26.02 % in 2010 and 5.34 % in 2007 for Crude palm oil, Mentha oil and Refined soya oil respectively. Maximum variation in prices of Mentha oil as well as Refined soya oil was explained by variation in Crude Palm oil prices ie R-square 0.770 and 0.685 respectively. Maximum variation in prices of Crude palm oil was explained by variation in Mentha oil prices ie R-square 0.770. Crude palm oil prices directly affect prices of mentha oil as well as refined soya oil, whereas crude palm oil prices are directly affected by refined soya oil prices.
