The Nature of Markets - Factors Influencing Demand and Supply

There is a whole range of factors that influence both demand and supply. The drag and drop exercise below lists some of these factors. You have to decide whether you think the factor concerned affects demand or supply and then drag the factor to the appropriate box.

Note that if you make a mistake you will only be able to tell by the amount you have got right out of the total. You will have to decide which ones are right and which are wrong!
