Production possibility curves：練習問題

An economy is capable of producing only two goods: Wheat and Steel. The following table shows various combinations of the two goods that can be produced using all available resources efficiently.

\(\begin{array}{|l|c|c|c|c|c|} \hline \text{Combination} & A & B & C & D & E \\ \hline \text{Wheat (units)} & 100 & 80 & 60 & 40 & 20 \\ \hline \text{Steel (units)} & 0 & 20 & 40 & 60 & 80 \\ \hline \end{array}\)

What can be concluded about the shape of the Production Possibility Curve (PPC) and the nature of resource allocation in this economy?

An economy is currently producing at a point on its Production Possibility Curve (PPC). If there is a sudden increase in the rate of unemployment, what will be the most likely effect on the PPC diagram?

An economy produces two goods, X and Y. The production possibilities are: \( (0X, 100Y) \), \( (20X, 90Y) \), \( (40X, 70Y) \), and \( (60X, 40Y) \). What is the marginal opportunity cost of increasing the production of X from \( 40 \) units to \( 60 \) units?

An economy produces two goods: Good X and Good Y. Its production possibility curve (PPC) is a straight line sloping downwards from the vertical axis (Good Y) to the horizontal axis (Good X).

What does the straight-line shape of this PPC indicate about the resources in this economy?

In a diagram showing a production possibility curve (PPC) with capital goods on the vertical axis and consumer goods on the horizontal axis, what would cause the curve to shift outwards from the origin?

Explain why a production possibility curve (PPC) is typically drawn as concave to the origin rather than as a straight line.

A country produces two goods, X and Y. If the Production Possibility Curve (PPC) is a straight downward-sloping line, what does this indicate about the opportunity cost of increasing the production of good X?

An economy is operating on its production possibility curve (PPC). If a technological innovation specifically improves the efficiency of Capital Goods production but has no effect on Consumer Goods production, describe the resulting change in the shape of the PPC and the impact on the marginal opportunity cost of producing Consumer Goods.

An economy produces two categories of goods: Agriculture and Technology.
(a) Explain what a Production Possibility Curve (PPC) illustrates about an economy's productive capacity.
(b) State two factors that would cause an outward shift of the PPC for this economy.

The following table shows the production possibilities for a country:

Production Point | Consumer Goods | Capital Goods
A | 0 | 100
B | 20 | 90
C | 40 | 70
D | 60 | 40
E | 80 | 0

(a) Calculate the opportunity cost of increasing the production of consumer goods from 20 to 40 units.
(b) Explain whether this economy is experiencing constant or increasing opportunity costs based on the data provided.
(c) Describe the significance of a point located at (30, 50) relative to this PPC.
