As the manager at a local florist, you supervise two employees, Anita and Jerome. There are two tasks that need to be completed: floral arrangements and flower delivery. It takes Anita 30 minutes to finish one floral arrangement and it takes her 40 minutes to make one delivery. It takes Jerome 10 minutes to finish one floral arrangement and it takes him 30 minutes to make one delivery.
a. Who has a comparative advantage in floral arrangements? What about deliveries?
b. Suppose, initially, Jerome and Anita each spent 4 hours each day doing floral arrangements and 2 hours each day doing deliveries. If you changed their tasks so that each individual did nothing but the task for which they had a comparative advantage, how many more floral arrangements would your store make, and how many more deliveries?

Each week Natalie can pick a maximum of 20 plums or 100 mushrooms and Grace can pick a maximum of 40 plums or 120 mushrooms. 1. After taking an economics class Natalie goes to her friend Grace and says they can increase production by working together and specializing. Grace says that she would prefer to work alone because she is better at both goods. What type of advantage does Grace have and is she correct in her assessment? 2. Calculate the comparative advantage for both Natalie and Grace for plums and mushrooms 3. Who should specialize in producing mushrooms and who should specialize in producing plums. 4. Assume that when they did not work together, Natalie picked 10 plums and 50 mushrooms and Grace picked 20 plums and 60 mushrooms.
