a) Determine which company has absolute advantage for each product
Company A has absolute advantage in CORN production, whereas Company B has in
WHEAT production.
b) Determine which company has comparative advantage for each product
Company A: 1 C = 1.25 W
Company B: 1 C = 3 W
Since company A has a lower opportunity cost, has a comparative advantage on CORN
production, whereas with a higher opportunity cost company B has comparative
advantage on WHEAT production as well.

b. Why does supply curve have an upward slope and demand curve have a downward
slope? Explain.
Price and quantity supplied have positively related, whereas Price and quantity
demanded has negatively related.
c. Determine Equilibrium Price and Quantity for Good A
P=50 Q=16
d. Determine the amount of surpluses and shortages at P=30 and P=60
If P=30 then there is an excess demand (shortage) with an amount of
24-10=14.
If P=60 then there is an excess supply (surplus) with an amount of
19-13=6.

tend to increase or decrease?
Excess Supply, 80-50=30 unit, Price tend to decrease
c. Is there excess demand or excess supply when price is 0.5? How much? Does price
tend to increase or decrease?
Excess Demand, 90-30= 60 unit, Price tend to increase
