If all consumers of the above three groups come together in a single market, the market demand curve would be Consumer group 1 Consumer group 2 Consumer group 3 2 10 2 10 25 8 10 27 21 24 24 13 25 01 11 10 10 11 12 0 2 11 10 7 10 11 13The following graph (where P stands for price and @ for quantity) reflects a change in the demand for a good (for simplicity, assume that each consumer demands at most one unit, as in the example in the videos). Given this change in demand we can conclude that: P Q O The reservation values have increased more for those consumers with higher reservation values O The reservation values have not changed, but the price of the good has increased O The reservation values have increased more for those consumers with lower reservation values O The reservation values of all consumers have increased equally
