The global economy Flashcards
What is international trade?
Exchange of goods, services, and resources between nations
Benefits of international trade?
- Increased competition
- Lower prices
- Greater choice
- Acquisition of resources
- More foreign exchange earnings
- Access to larger markets
- Economies of scales
- More efficient resource allocation
-More efficient production
Absolute advantage?
Occurs when a country is able to produce a product using fewer factors of production than another country
Comparative advantage?
When a country can produce a good or service at a lower opportunity cost than another country.
Sources of comparative advantage?
- Factor endowments: Some countries naturally endowed to certain resources
- Exchange rate fluctuations: Appreciation of domestic currency means imports are cheaper while exports become more expensive for foreign buyers
- Price stability: Inflation in the domestic country causes demand for exports to fall while demand for imports will rise
- Levels in technology: Latest access to machinery and technology more productive. High income countries will have more financial ability to invest in better technology so comparative advantage over low income countries
- Investment in R&D: Countries that invest in R&D and innovation improves ability to increase productive capacity and lowers opportunity cost
Limitations of theory of comparative advantage?
- creates a dependence on other countries which generates vulnerability
- impact of negative externalities of production is not considered
- distribution of the extra income is likely to be uneven
- certain industries are likely to shut down resulting in unemployment for some workers
Trade protection
Government policies aimed to restrict imports to protect domestic producers: tariffs, quotas, subsidies, adminisrative barriers
Tariffs
A tariff is a tax on imported goods/services. Higher price allows more inefficient domestic firms to increase their production and market share
Tarrifs effects on stakeholders?
Domestic producers: Better off as they sell at higher quantity and higher price
Consumers: Worse off as they pay higher price for lower quantity
Foreign producers: Worse off as they sell at lower quantity at same price
Government: Earns tax revenue
Total welfare: Decreases, more units being produced from inefficient producers and consumers pay higher price for lower quantity
How to calculate consumer expenditure tariff?
Consumer expenditure: Price X Quantity
Before Tariff: Pw X Q2
After tariff: (Pw+T) x Q4
How to calculate consumer surplus tariff?
Before tariff: Area G,F,B,C,D,E
After tariff: Area G,F
How to calculate producer revenue tariff?
Revenue = Price X Quantity
Before Tariff: Pw X Q1
After Tariff: (Pw+T) x Q3
How to calculate producer surplus tariff?
Before Tariff: (Pw - min price) x Q1 / 2
After Tariff: ((Pw+T) - min price) x Q3 / 2
How to calculate foreign producer revenue tariff
Revenue = Price X Quantity of imports
Before tariff = Pw X (Q2-Q1)
After tariff = Pw X (Q4-Q3)
How to calculate government revenue tariff
Revenue = ((Pw-T) - Pw) X (Q4-Q3)
How to calculate welfare loss tariff
(T x (Q3-Q1)) / 2 + (T x (Q2-Q4)) / 2
Pros / Cons of Tariffs
Pros:
- Government receives revenue
- Supports domestic producers and jobs
Cons:
- Trade off between domestic employment and inefficient allocation of resources
- Consumers pay higher price and have less options
- Foreign producer revenue decreases
- May result to retaliation and long term breakdown of political relationships
- Encourages productive inefficiencies as domestic firms reliant on this form of protection rather than performing competitively
Quota
A quota is a physical limit on imports. This limit is usually set below the free market level of imports
- As cheaper imports are limited, a quota raises the market price and create shortages
Quota effect on stakeholders
Domestic producers: Better off as they sell at higher quantity and higher price
Consumers: Worse off as they pay higher price for lower quantity
Foreign producers: May generate higher or lower sales revenue depending on PED, PES and size of quota
Government: No tax revenue
Total welfare: Decreases, more units being produced from inefficient producers and consumers pay higher price for lower quantity
Production subsidies
Refers to sum of money which government provides to domestic producers for producing each unit of the subsidized good
How to calculate consumer surplus quota
Before : (Max price - Pw) x Q2 / 2
After : (Max price - (Pq)) x Q4 / 2
How to calculate domestic producer revenue quota
Revenue = Price X Quantity
Before: Pw X Q1
After: (Pq) x Q3
How to calculate producer surplus quota?
Before : (Pw - min price) x Q1 / 2
After : ((Pq) - min price) x Q3 / 2
How to calculate foreign producer revenue quota
Revenue = Price X Quantity of imports
Before = Pw X (Q2-Q1)
After = Pq X (Q4-Q3)
