Production possibilities frontier (PPF)2. The limitation of production choice Country A has limited resources
not able to choose combination F (any point beyond the PPF) Country A will maximize the production
not produce at combination E (any point within the PPF) at any point within the PPF, producing more of any one good without
reducing the quantity of another.
Conclusion At any point on the PPF
Resources are fully utilized Production efficiency is attained
Production decision will be on the PPF only
![Page 8: Economics Elective 2 Chapter 1 Extension of Trade Theory 1](https://reader034.vdocuments.us/reader034/viewer/2022052302/56649f3e5503460f94c5e975/html5/thumbnails/8.jpg)
Production possibilities frontier (PPF)
3. The opportunity cost of production
a. Downward sloping PPF
Assume there’s only 2 products
Under scarcity, producing more Good X means less Good Y
Therefore
The opportunity cost of producing X is “Y”.
The opportunity cost of producing Y is “X”.
![Page 9: Economics Elective 2 Chapter 1 Extension of Trade Theory 1](https://reader034.vdocuments.us/reader034/viewer/2022052302/56649f3e5503460f94c5e975/html5/thumbnails/9.jpg)
Production possibilities frontier (PPF)
3. The opportunity cost of production
b. Sloping of PPF = Opportunity cost
Suppose original production is at point B
If production moves from point B to C
Produce 1 more unit of Good X
Give up producing 2 units of Good Y
That is, marginal cost of 1X = 2Y
![Page 10: Economics Elective 2 Chapter 1 Extension of Trade Theory 1](https://reader034.vdocuments.us/reader034/viewer/2022052302/56649f3e5503460f94c5e975/html5/thumbnails/10.jpg)
Production possibilities frontier (PPF)3. The opportunity cost of production
b. Sloping of PPF = Opportunity cost From the graph:
Slope of PPF = = -2
Meaning that 2Y will be given up for producing 1X.
So, the opportunity cost of 1X is 2Y.
-2Y
+1X

Production possibilities frontier (PPF)
3. The opportunity cost of production
b. Sloping of PPF = Opportunity cost
As the opportunity cost of producing 1X = 2Y
Then, the cost of producing 1Y = X
Meaning that X will be given up for producing 1Y.
Reciprocal of slope of PPF = = -
Reciprocal of cost of Good X

3. The opportunity cost of production
b. Sloping of PPF = Opportunity cost
Conclusion
Given a straight PPF with constant slope
where x-axis is Good X and y-axis is Good Y
Marginal cost = Average cost
The slope of PPF is the MC of Good X
The reciprocal of the slope is the MC of Good Y

Trade theory
Using the PPF to illustrate The principle of comparative advantage The advantages of international trade
Assumption Marginal cost is constant PPF is a downward sloping straight line
![Page 23: Economics Elective 2 Chapter 1 Extension of Trade Theory 1](https://reader034.vdocuments.us/reader034/viewer/2022052302/56649f3e5503460f94c5e975/html5/thumbnails/23.jpg)
Trade theory1. Consumption choice in an autarkic economy
The consumption possibilities frontier shows the locus of the maximum combinations of consumption of an economy
Without international trade, consumption is restricted by its production
So, PPF = consumption possibility frontier
Given the PPF of Country A Under autarky,
if production at point Cthe max. consumptioncombination is 2X and 2Y
So, consumption can’t exceed PPF.
Points inside are attainable consumption combinations.
![Page 24: Economics Elective 2 Chapter 1 Extension of Trade Theory 1](https://reader034.vdocuments.us/reader034/viewer/2022052302/56649f3e5503460f94c5e975/html5/thumbnails/24.jpg)
Trade theory2. Trade line (Price line)
A straight line passing through the production point, which shows the consumption opportunities brought by trade.
Suppose Country A produces 2X and 2Y (point C) Under autarky, it’s max.
consumption combination.
If trade with other country with international price 1X = 1Y

Trade theory
2. Trade line (Price line) For international trading, Country A
Exchanges X for Y, it can move from point C to P or Q
or Exchanges Y for X, it can move from point C to R or S
Country A can consume at any point along the trade line
Slope of trade line = 1
MC of X = 1Y

Trade theory
3. Changes in consumption possibilities From given data
Opportunity cost of producing 1X = 2Y Opportunity cost of producing 1Y = 0.5X Terms of trade (International price): 1X =1Y
Production cost of 1Y is less than the international price Country A has a comparative advantage in producing Good Y,
because its production cost of Good Y is lower. Therefore, Country A should specialize in producing Good Y. Then, trade Good Y for Good X.

Two-country model2. Specialization and trade according to
comparative advantage
From PPFs,
Slope of PPFA = = - 2mean that the opportunity cost producing 1X is 2Y
Slope of PPFB = = - 0.5mean that the opportunity cost producing 1X is 0.5Y
Country B has lower cost in producing Good X (given up less Y)
i.e. Country B has comparative advantage in producing Good X
and Country A has comparative advantage in producing Good Y
Mutual beneficial term of trade: 2Y > 1X > 0.5Y
[ International price 1X=1Y is mutually beneficial ]

Two-country model3. Gain from trade
In conclusion
Without trade:
Country A produces 2X and 2Y
Country B produces 2X and 2Y
World total output = 4X and 4Y
After trade
Country A produces 6Y
Country B produces 6X
World total output = 6X and 6Y
Overall gain = 2X and 2Y, which are equally shared by Country A and Country B in previous example

Two-country model4. From PPF of 2 countries to the PPF of the world
If Country A & B produce Good Y only,
Country A produces 6Y and Country B produces 3Y
World total output = 0X and 9Y (Combination P)
Base on the principle of comparative advantage, with trade
World total output = 6X and 6Y (Combination Q)
If Country A & B produce Good X only,
Country A produces 3X and Country B produces 6X
World total output = 9X and 0Y (Combination R)
Base on the principle of comparative advantage, with trade
World total output = 6X and 6Y (Combination Q)

![Page 55: Economics Elective 2 Chapter 1 Extension of Trade Theory 1](https://reader034.vdocuments.us/reader034/viewer/2022052302/56649f3e5503460f94c5e975/html5/thumbnails/55.jpg)
Comparative advantage and its relationship with globalization
2. Globalization of production activities
a. Changes in the nature of international division of labour Definition of international division of labour
In the past specialize in producing goods which they have comparative advantage a country specialized in producing whole products e.g. US produced a whole car locally.
Nowadays specialization of the part of goods which comparative advantage different countries specialize in producing different parts of the same
product e.g. Tablet computer
Hardware from China and software from Japan or Korea
![Page 56: Economics Elective 2 Chapter 1 Extension of Trade Theory 1](https://reader034.vdocuments.us/reader034/viewer/2022052302/56649f3e5503460f94c5e975/html5/thumbnails/56.jpg)
Comparative advantage and its relationship with globalization
2. Globalization of production activities
b. Dynamic comparative advantage the comparative advantage in a good or component part will shift
from one region to another with changes in economic development.
For example In the past 10-20 years, HK imported Japanese automobiles Recently, HK imports Korean and European automobiles Less comparative advantage due to:
High production cost and exchange rate in Japan Technology of automobile outflow and modified by other countries Lower production cost in other countries due to economic growth
FDI helps bringing new technologies from developed countries to developing countries
Production is relocated to countries with lower production cost
![Page 57: Economics Elective 2 Chapter 1 Extension of Trade Theory 1](https://reader034.vdocuments.us/reader034/viewer/2022052302/56649f3e5503460f94c5e975/html5/thumbnails/57.jpg)
