Module 12 Flashcards
What is the PPF and what does it show?
Production Possibilities Frontier.
Combinations of goods possible to produce.
How do we shift the PPF outwards?
Economic growth:
- Use resources to create more capital goods.
- Improve technology.
What are the assumptions of the PPF?
- all resources are used effectively
- all other resources are fixed, especially technology
Looking at a PPF, Which points are efficient?
Any point on it. Points outside it are impossible and points inside are inefficient.
Why is the PPF curved?
Increasing marginal opportunity cost due to specialization of resources.
Why does Comparative Advantage exist?
Differing opportunity costs.
How does trade leave people better off?
- Allowing them to specialize where they have the lowest opportunity cost.
- This allows them to consume outside their PPF.
What is comparative advantage?
Having a lower opportunity cost to produce a good or service than someone else.
What is absolute advantage?
Being more efficient at producing a good or service (more production given same resources).
Which is the basis for trade? Comparative or Absolute Advantage?
Comparative advantage is the basis for trade because it allows gains from specialization.
If two producers have the same opportunity cost, does trade benefit them?
No
What are the main sources of comparative advantage?
- Climate and natural resources
- Relative abundance of labour and capital
- Technology
- External economies
What is autarky?
When a country refuses to have any trade partners.
Why don’t we see complete specialization in trade?
- increasing marginal opportunity cost
- consumer tastes
- some goods / services are not traded
Does everyone gain from specialization?
No - there are winners and losers but overall the economic surplus increases.
What is Free Trade
no restrictions
What happens to economic surplus under free trade?
- CS increases
- PS decreases
- Peq falls to Pworld
What happens to economic surplus under tariffs?
- Loss of consumer surplus
- Increase in producer surplus
- Gov gets $
- DWL
Which area represents the loss of consumer surplus with a tariff?
ACTD
