There are many undesirable effects in the increase, such as: decrease the purchase power of buyer and make  financial loses. Therefore it is important to analyze price dynamics of corn. The objectives of this research are to analyze the supply response in corn market, analyze corn price volatility in Indonesia, and choose the appropriate GARCH (Generalised Autoregressive Heteroscedastic) model to express price volatility.

The methodology of this research uses GARCH model. The empirical results show that price volatility is an important risk factor.
