Editing Cross elasticity of demand (section)

=== Contribution to policy improvement===
The UK and Scottish governments intended to use price-based policy interventions, like setting minimum unit pricing and increasing taxation to reduce alcohol consumption and mediate the related harms among their population.<ref>{{cite journal |title=Estimation of own and cross price elasticities of alcohol demand in the UK—A pseudo-panel approach using the Living Costs and Food Survey 2001–2009 |journal=Journal of Health Economics |date=1 March 2014 |volume=34 |pages=96–103 |doi=10.1016/j.jhealeco.2013.12.006|last1=Meng |first1=Yang |last2=Brennan |first2=Alan |last3=Purshouse |first3=Robin |last4=Hill-Mcmanus |first4=Daniel |last5=Angus |first5=Colin |last6=Holmes |first6=John |last7=Meier |first7=Petra Sylvia |issue=100 |pmid=24508846 |pmc=3991422 }}</ref> Estimation of cross-price elasticities of alcohol in respect to other related beverages helps set price-based policy interventions, as it measures the percentage change in demand for one type of alcohol due to a 1% change in the price of another type of beverage. For example, the cross elasticity of demand for wine in respect to the price change of spirit is 0.05, which implies that a 1% price decrease for Spirit will reduce market demand for wine by 0.05%. Therefore, the cross elasticity of demand enables policymakers to take better control of the policy effects, thus, reducing the risk for mortality, morbidity, and other social harms caused by over-drinking.
