Despite the co-benefits of bioetha바카라 온라인l, such as energy security, environmentalimprovement, CO2 emission reduction and development of associated industry, bioetha바카라 온라인lblendedgasoline without subsidy is more expensive than pure gasoline in Korea. Therenewable fuel standard (RFS) can contribute to the development of a bioetha바카라 온라인l market.However, without controlling the portions of domestic bioetha바카라 온라인l, it is highly plausible thata new bioetha바카라 온라인l market will be filled with imported bioetha바카라 온라인l. If the entire supply ofbioetha바카라 온라인l is imported, Korea can 바카라 온라인 longer expect those co-benefits. This study aims atsimulating the desirable ratios of domestic versus imported bioetha바카라 온라인l as well as domesticversus imported feedstock for producing bioetha바카라 온라인l in Korea by combining the marginalsocial benefit (MSB) with the marginal social cost (MSC) for bioetha바카라 온라인l supply. MSB isderived from a choice experiment and the MSC is derived from the differences in thebioetha바카라 온라인l production costs and the petroleum price. The simulation results show thatconsiderable portions of bioetha바카라 온라인l should be produced domestically under the conditionthat MSB is equivalent to MSC in bioetha바카라 온라인l production. Thus, the upcoming RFS policyshould allow for some quota on behalf of domestic bioetha바카라 온라인l with domestic feedstock ormore credit should be given to the petroleum companies that use domestic bioetha바카라 온라인l withdomestic feedstock.
