Hey, I have to do a report affecting Supply & Demand in a cetain area (Property Based) anyway I have to obviously acompany it with Diagrams and drawing my first I wanted to show that the price went up but no new houses were built, so to me this suggests Price goes up but quantity does not change right? so does this mean the Demand curve shifts out to the right? or does quantity have to go down if price goes up? I thought the demand curve will only shift if Quantity Demand goes up?!? Really confused!
