If Elizabeth can make 3 pies or bake 6 cakes per hour and Benjamin can make 2 pies or bake 8 cakes per hour, _____.

Elizabeth has the comparative advantage in baking cakes

Elizabeth should specialize in making pies

Benjamin should specialize in making pies

Benjamin has the comparative advantage in making pies

1 answer

To determine who has the comparative advantage, we need to analyze the opportunity cost for both Elizabeth and Benjamin when they make pies versus cakes.

For Elizabeth:

  • In one hour, she can make 3 pies or 6 cakes. Therefore:
    • The opportunity cost of making 1 pie = 6 cakes / 3 pies = 2 cakes
    • The opportunity cost of making 1 cake = 3 pies / 6 cakes = 0.5 pies

For Benjamin:

  • In one hour, he can make 2 pies or 8 cakes. Therefore:
    • The opportunity cost of making 1 pie = 8 cakes / 2 pies = 4 cakes
    • The opportunity cost of making 1 cake = 2 pies / 8 cakes = 0.25 pies

Now we can summarize:

  • Elizabeth's opportunity cost for pies: 2 cakes per pie
  • Benjamin's opportunity cost for pies: 4 cakes per pie

Since Elizabeth has a lower opportunity cost for making pies than Benjamin (2 cakes vs. 4 cakes), she has the comparative advantage in baking pies.

On the other hand:

  • Benjamin’s opportunity cost for cakes: 0.25 pies per cake
  • Elizabeth's opportunity cost for cakes: 0.5 pies per cake

Since Benjamin has a lower opportunity cost for making cakes than Elizabeth (0.25 pies vs. 0.5 pies), he has the comparative advantage in baking cakes.

In conclusion:

  • Elizabeth should specialize in making pies.
  • Benjamin should specialize in baking cakes.

Given the options provided, the correct answer is: Elizabeth should specialize in making pies.
