Price elasticity of demand is the degree of responsiveness in terms of desire for the product, as the price changes. If the price rises, than people will desire less while if the price reduces, then people will demand more. Price elasticity of demand is high when demand changes when the price changes, price elasticity is low when demand does not change even when price changes.
Jasmine rice is a healthier version of white rice as it contains more fiber. There are other varieties of rice also available such as Basmati, and popcorn rice. Thus even if Jasmine rice has several substitues, it is comparatively cheaper than Basmati rice. If one doesn't get Jasmine rice then he/she can always opt for other variants of Rice. Thus it is not a luxury good, but nor is it a necessity as people can adjust to different diets. Although Jasmine rice is broadly defined in the rice category as fibrous, it has a fragrant smell, and is a healthy alternative. Thus price elasticity will be higher for Jasmine as it is not necessarily a necessity, people can opt for other goods, so if the price increases, the demand will reduce and not be the same. Elasticity will be higher in the long run as people will opt for other alternatives and completely take over the market if Jasmine rice turns out to be overexpensive. It all depends on variables such as taste, preferences and income of individuals. If per capita income is high, then the price elasticity will be lower, but if income is low, then price elasticity of demand will be higher as people will opt for other alternatives.
