Yesterday my host father showed me a news which is the carmaker confirmed 850 job cuts at the BMW's Mini Cowley plant in Oxford .
why this happend?
I think , because of the recession , the aggregate demand goes down , and the consumption decrease too, that means people do not want buy new MINI cars,the demand of this car go down,
The income of the company go down,because of this , this company may face the problem which is cash flow, they do not have enough money to make cash flow work which means they may can not give their labour wages .Therefore, they need think about some ways to deal with this problem,
The way is redundancies and it can decrease the cash flow . In fact I think they can use some other ways , for example, decrease the supply or decrease the cost which means cut the sell price,, not a lot but a few, and also can add some benefits, like buy a car get something free. Also they can look for some investment , even though the chances are less than before, but they need try, because they have a famous brand of their products, some people will interested in.
