Economic Principles of Advantage, Specialization, and Trade

Production Possibilities Frontier (PPF)

A curve that illustrates the maximum output combinations of two goods that can be produced with a given set of inputs.

Opportunity Cost

The value of what must be given up to produce an additional unit of another good, calculated by examining trade-offs along the PPF.

Comparative Advantage

The ability of a producer to create a good at a lower opportunity cost than another.

Absolute Advantage

The ability of a producer to produce more of a good using the same amount of inputs than another.

Marginal Cost

The opportunity cost of producing one more unit of a good.

Specialization

The process of focusing resources on producing a good in which a producer has a comparative advantage.

Mutually Beneficial Trade

A trade that is advantageous for both parties because the exchange rate lies between their opportunity costs.

Charlie's PPF

A straight line connecting the output of 30 cups and 10 plates, illustrating his production capacity and opportunity cost.

Opportunity Cost Calculation

The method used to determine the cost of forgoing the next best alternative when a choice is made.

Trade Rate

The exchange rate at which specialized producers trade their surplus goods, ideally less than their own internal opportunity cost.
