#1
- supply falls
- demand falls
- demand rises (due to the expected future price increase), the used Caddy
gets poor gas mileage so its demand falls
#3
- tastes change (or number of buyers increases), demand increases, P and Q
both
increase
- production costs rise, supply decreases, P
increases
and Q
decreases
- technology improves, supply increases, P
decreases and Q
increases
- the price of a substitute rises, demand increases, P and Q both increase
#7
- supply decreases,
P
increases
and Q
decreases
- demand decreases (if leather jackets and sweatshirts are substitutes), P
and Q both decrease
- demand increases, P and Q both increase
- supply increases, P decreases and Q increases
