Methodology: Thepriceelasticityofdemandmeasuresthepercentagechangeinquantitydemandedinresponsetoaonepercentchangeinprice.Thedouble-logmodeliscommonlyusedtoestimatepriceelasticity,especiallyinsituationswhereboththepriceandquantitydemandedarelikelytochangesimultaneously.Theequationforthedouble-logmodelisasfollows: ln(Qd)=α+β*ln(P)+ε, Where: Qd=Quantitydemandedofagriculturalproducts P=Priceofagriculturalproducts α=Intercept β=Priceelasticitycoefficient ε=Errorterm Toestimatethepriceelasticityofimportdemand,thedataonthequantitydemandedandpriceofagriculturalproductswillbecollectedoveracertainperiod.Thedatacanbeobtainedfromgovernmentreports,internationaltradedatabases,andotherrelevantsources.Thelogarithmtransformationofthedatawillbeperformed,andalinearregressionanalysiswillbeconductedusingstatisticalsoftwaretoestimatethevaluesofαandβ.
