There are, at least, three options of marketing institutions available for smallholders rubber plantations, i.e. auction market, partnership, and traditional (intermediary trader) institutions. This study analyzes factors affecting the probability of smallholder rubber plantation option for alternative marketing institutions. The findings show that factors significantly affecting the probability of option for market compared with intermediary trades are availability of price information, simplicity of transaction procedures, and period of transactions at auction market, all with negative response elasticities. The probability of option for partnership institutions compared with traditional traders is significantly affected by simplicity of transaction procedures, periods of transactions, and rubber?s price uncertainty in partnership institutions, all with negative response elasticities.
