Тест: Understanding Long-Term Economic Growth — 10 въпроса

1. What is the primary driver of long-term economic growth according to the Solow model with technical progress?

A. Capital accumulation alone

B. Exogenous technological progress

C. Government spending

D. Labor force growth

Answer: (B)

Обяснение

The Solow model with technical progress emphasizes that long-term growth is driven by exogenous technological progress (A), which increases productivity independently of capital and labor accumulation. Capital accumulation alone leads to diminishing returns and cannot sustain growth indefinitely.

2. What does the Solow growth model predict about countries with different initial capital per worker?

A. They will diverge over time, with richer countries growing faster.

B. Poorer countries tend to grow faster and catch up to richer ones, due to diminishing returns to capital.

C. Growth rates are unaffected by initial capital and remain constant.

D. Both rich and poor countries grow at the same rate, specified by technological progress.

Answer: (B)

Обяснение

The convergence hypothesis explains that poorer countries grow faster because of diminishing returns to capital, allowing them to catch up to richer countries over time, which is a core prediction of the Solow model.

3. Which of the following best describes the concept of convergence in economic growth?

A. Poor countries grow faster than rich countries, catching up over time

B. Convergence only occurs in countries with similar cultural backgrounds

C. All countries grow at the same rate regardless of initial income levels

D. Rich countries grow faster than poor countries, widening income gaps

Answer: (A)

Обяснение

Convergence hypothesis suggests that poorer countries tend to grow faster than richer ones, allowing them to catch up in income levels over time, primarily due to diminishing returns to capital and technology transfer.

4. Which component of GDP growth is not directly explained by increases in capital and labor inputs?

A. Total Factor Productivity (TFP).

B. Capital accumulation.

C. Labor input.

D. Diminishing marginal returns.

Answer: (A)

Обяснение

Total Factor Productivity (TFP) captures residual growth in GDP not explained by capital and labor, often attributed to technological progress or efficiency gains.

5. In the context of the Cobb-Douglas production function, what does the parameter α represent?

A. The elasticity of output with respect to labor

B. The rate of technological progress

C. The depreciation rate of capital

D. The share of output paid to capital

Answer: (D)

Обяснение

In the Cobb-Douglas production function Y = K^α * L^(1-α), α represents the output share attributed to capital, indicating how much of the output is due to capital input relative to labor.

6. Which of the following best describes the Cobb-Douglas production function?

A. Y = K + L

B. Y = K^α L^(1-α) where 0<α<1.

C. Y = A * (K + L)

D. Y = A * K * L

Answer: (B)

Обяснение

The Cobb-Douglas production function is expressed as Y = K^α L^(1-α) with 0<α<1, representing a multiplicative form where output depends on capital and labor with diminishing returns.

7. What does the GDP deflator measure?

A. The ratio of nominal GDP to real GDP, indicating overall price level changes.

B. The change in the quantity of goods produced.

C. The level of technological progress.

D. The growth rate of GDP per capita.

Answer: (A)

Обяснение

The GDP deflator is the ratio of nominal GDP to real GDP and measures overall changes in price levels across the economy.

8. According to the revision sheet, what trend has been observed since the 1970s regarding economic growth?

A. Growth rates have accelerated globally.

B. Growth rates have slowed, and convergence has become less pronounced.

C. All countries have achieved complete convergence.

D. Growth rates have become entirely determined by endogenous technological change.

Answer: (B)

Обяснение

Since the 1970s, growth rates have slowed, and the phenomenon of convergence has become less noticeable, indicating diminishing prospects for catch-up growth.

9. What does the steady state refer to in the context of the Solow growth model?

A. A situation where capital per worker and output per worker are growing exponentially.

B. A state where capital per worker and output per worker stop growing and remain constant.

C. The point at which technological progress begins.

D. The maximum possible level of GDP.

Answer: (B)

Обяснение

The steady state in the Solow model refers to an equilibrium where capital and output per worker cease to grow, unless driven by technological progress.

10. Which factor is modeled as exogenous in the Solow model and essential for long-term growth?

A. Technological progress (A).

B. Savings rate.

C. Population growth.

D. Depreciation rate.

Answer: (A)

Обяснение

In the Solow model, technological progress (A) is taken as exogenous and responsible for sustained long-term growth, since capital accumulation alone leads to diminishing returns.
