Production possibility curve (PPC) diagrams：练习题

What does any point lying directly on a production possibility curve (PPC) indicate about an economy?

An economy produces consumer goods and capital goods. If a breakthrough in robotics exclusively improves the efficiency of producing capital goods while leaving consumer goods unaffected, how will the PPC change?

An economy is currently operating at a point inside its production possibility curve due to widespread structural unemployment. The government implements successful training programs that eliminate this unemployment, and simultaneously discovers a major new domestic oil reserve. Which of the following best describes the resulting graphical changes?

What is the primary reason why a standard production possibility curve (PPC) is bowed outwards (concave to the origin)?

Why do production possibility curves (PPCs) typically exhibit an increasing opportunity cost, resulting in a bowed-outwards (concave) shape?

Using a Production Possibility Curve (PPC) diagram, analyze how a government's decision to reallocate resources from consumer goods to capital goods affects the economy's position on the curve and its opportunity cost.

An economy discovers significant new offshore oil reserves. Using a Production Possibility Curve (PPC) diagram, explain how this discovery affects the economy's productive capacity over the long term.

In a Production Possibility Curve (PPC) diagram, analyze the economic significance of a shift of the entire curve to the right in terms of an economy's potential growth.

A country's economy is currently producing at a point on its Production Possibility Curve (PPC), where it allocates resources between "Education Services" and "Luxury Goods".

a) Explain, using the concept of opportunity cost, what happens if the government decides to move along the PPC to increase the provision of Education Services.

b) Describe how a significant increase in the quality of the country's labour force would be illustrated on the PPC diagram and what this represents for the economy.

An economy produces only two types of goods: agricultural products and industrial machinery. Initially, the economy is operating at a point on its Production Possibility Curve (PPC).

a) Using a PPC diagram, illustrate the effect of a significant technological advancement that improves productivity in both the agricultural and industrial sectors. Explain the resulting change in the economy's productive potential.

b) Discuss whether a movement from a point inside the PPC to a point on the PPC represents the same type of economic growth as an outward shift of the entire curve.
