Example of price fall caused by slump in demand - the Chinese Mink market

Have a read of this fascinating article from the Guardian about the fall in prices for mink fur in China. It struck me that, not only does the article give you several traditional causes of a slump in demand (let's all draw the diagram!) but comes up with a brand new cause of a shift that I've not seen before!The article suggests that the shift in demand is caused by a warmer than expected winter (tick, weather conditions) and that an increase in the number of educated Chinese people are choosing not to use mink for ethical reasons (tick, change in tastes). It also says that demand has dropped as the Chinese government are clamping down on corporate corruption preventing Chinese directors from accepting luxury goods in return for favourable business decisions - which of our Economics Teacher categories does that fit in?PS. Look out for the fantastic activity 'Demand Street', which challenges students to work out what change in demand factor is being demonstrated, showcased at this year's Wow Economics Teacher CPD event fro Tutor2u.
