Abstract: Price of onion shows a high degree of volatility. Price volatility is said to be asymmetric when it is affected by positive and negative shocks of same magnitude with different degree. Asymmetric volatility can be captured by asymmetric GARCH type of model such as EGARCH, APARCH and GJR-GARCH. Weekly modal price of onion for Delhi, Lasalgaon and Bengaluru markets are modelled with the help of these asymmetric variance models. For the present investigation, APARCH model outperformed the other competing models and it is considered as the best fit model for the data under consideration. Finally, the extent of asymmetry due to positive and negative shocks for all these markets are visualised with the help of News Impact Curves.
