Answer:
A decrease in the supply of office space, shifting supply to the left.
Explanation:
A decrease in supply can take place as shift to the left or upwards in a supply curve. In this case, a left shift indicates that, in the time that the supply of office space decreases, firms that own office buildings produce and sell a smaller amount at every price. The upward shift shows that supply usually decreases when the production costs increase, so producers must set a higher price than in the past to supply an established quantity of output.
