Abstract:
The agricultural future prices so-called price discovery is the outcome of the agricultural future exchange market. Investors, hedgers and speculators are able to use this information so as to form expectations for the future trend. As a results, this information will allow investors and producers to efficiently produce and export agricultural products with the lower volatility of spot price. The study analyzed the impact of the establishment of the agricultural future exchange market on the volatility of the ribbed smoked rubber sheet no. 3 price in spot market. The model consists of one dependent variable; the ribbed smoked rubber sheet no. 3 price, and five independent variables; lagged price of the ribbed smoked rubber sheet no. 3, lagged exported quantities of the ribbed somked rubber sheet no. 3, average incomes of Thailand's major trading partners, namely, China, Japan and the United States of America, oil prices and dummy varibles representing the estableshment of the agricultural future exchange of Thailand. Our analysis is composed of three parts. The first part considers the factors determining the spot price of the ribbed somked rubber sheet no. 3 market. The next and the last parts investigate impacts of the agricultural future exchange of Thailand on spot prices and the volatility of spot prices, respectively. The volatility transmission from agricultural future exchange markets to spot markets is estimated by applying the ARCH-GRACH model. The result shows that the agricultural future exchange of Thailand does not cause the volatility transmission of the ribbed smoked rubber sheet no.3 price in spot markets; in other words, it has no effects on the volatility of the ribbed smoked rubber sheet no. 3 price in spot markets. There are two policy recommendations for the agricultural future exchange of Thailand to reduce the volatility of agricultural prices. The agricultural future exchange of Thailand needs to regularly perform self-auditing with respect to its objectives and widely introduce and educate the use of the agricultural future exchange market to farmers.
