Production, Economic Growth, and Trade

Basic Economic Questions & Production

• Three Basic Economic Questions:

  • What goods and services will be produced?

  • How will these goods and services be produced?

  • Who will receive the goods and services produced?

• Factors of Production:

  • Land: Natural resources used in production.

  • Labor: Human effort exerted during production.

  • Capital: Manufactured items used to produce other goods and services.

  • Entrepreneurial Ability: Innovation, risk-taking, and management skills required to organize resources.

• Production Definition: The process of converting factors of production into outputs (goods and services).

Economic Efficiency Concepts

• Production Efficiency: Achieved when goods and services are produced at their lowest resource (opportunity) cost.

• Allocative Efficiency: Achieved when the mix of goods and services produced represents what society desires.

• Pareto Efficiency: Achieved when payoffs or well-being can be improved for someone without making anyone else worse off.

Production Possibilities Frontier (PPF)

• Definition: A model that shows the combinations of two goods a society can produce at full employment.

• Law of Increasing Opportunity Cost: Opportunity cost increases as more of a product is produced, creating a bowed-out curve.

• Economic Growth:

  • Short-Run Growth: Moving from an inefficient point inside the frontier ($a$) to an efficient point on the frontier ($b$ or $c$).

  • Long-Run Growth: Shifting the entire frontier outward from a point on the curve ($b$ or $c$) to an exterior point ($d$).

• PPF Shifts:

  • One-Product Change: An improvement affecting only one product pivots the PPF outward along that product's axis.

  • All-Product Change: General technological or resource growth shifts the entire PPF outward for all products.

Absolute and Comparative Advantage

• Absolute Advantage: The ability of a country to produce more of a good than another country using the same amount of resources.

• Comparative Advantage: The ability of a country to produce a good at a lower opportunity cost than another country.

• Distributional Effects of Trade:

  • Winners: Import consumers (lower prices) and export producers (larger market access).

  • Losers: Export consumers (higher domestic prices) and import-competing producers (foreign competition).

Advantage Calculations and Examples

• USA vs. Italy (Music & Pizza):

  • USA: $8\text{ Music}$ or $4\text{ Pizza}$ ($1\text{ Music} = 0.5\text{ Pizza}$, $1\text{ Pizza} = 2\text{ Music}$).

  • Italy: $6\text{ Music}$ or $8\text{ Pizza}$ ($1\text{ Music} = 1.33\text{ Pizza}$, $1\text{ Pizza} = 0.75\text{ Music}$).

  • USA holds comparative advantage in Music ($0.5 < 1.33$).

  • Italy holds comparative advantage in Pizza ($0.75 < 2$).

• Iceland vs. Denmark (Lumber & Sleds):

  • Iceland daily capacity: $3\text{ Lumber}$ or $6\text{ Sleds}$ ($1\text{ Lumber} = 2\text{ Sleds}$).

  • Denmark daily capacity: $4\text{ Lumber}$ or $12\text{ Sleds}$ ($1\text{ Lumber} = 3\text{ Sleds}$).

  • Iceland has comparative advantage in Lumber ($2\text{ Sleds} < 3\text{ Sleds}$).

  • Denmark has comparative advantage in Sleds ($\frac{1}{3}\text{ Lumber} < \frac{1}{2}\text{ Lumber}$).

• France vs. Germany (Violins & Electric Shavers):

  • France capacity: $100\text{ Violins}$ or $250\text{ Electric Shavers}$.

  • Germany capacity: $200\text{ Violins}$ or $300\text{ Electric Shavers}$.

  • Absolute Advantage in Shavers: Germany ($300 > 250$).

  • Comparative Advantage in Shavers: France, because its opportunity cost ($1\text{ Shaver} = 0.4\text{ Violin}$) is lower than Germany's ($1\text{ Shaver} = 0.67\text{ Violin}$).
