Question 1

In the Solow growth model, what is the 'Golden Rule' level of capital per worker ($$k^*) $$and how is it determined?

Accepted Answer

It is the level of capital per worker where the marginal product of capital equals the sum of the population growth rate and depreciation rate: $$MPK = n + d$$

Question 2

According to the Solow model, which of the following will NOT lead to long-term economic growth?

Accepted Answer

Continuous technological progress

Question 3

If a country is below its Golden Rule level of capital per worker, what is the effect of increasing the savings rate?

Accepted Answer

It will increase both capital per worker and consumption per worker in the long run

Question 4

Which equation best represents the steady-state condition for capital per worker in the Solow model?

Accepted Answer

$$s f(k^*) = (n + d) k^*$$

Question 5

What is the main reason why countries may not converge to the same standard of living according to the Solow model?

Accepted Answer

Barriers to the adoption of new technologies ($$z)$$

Question 6

In the Solow model, what happens to consumption per worker if the capital per worker exceeds the Golden Rule level?

Accepted Answer

Consumption per worker decreases because more output is used for capital maintenance

Question 7

Which of the following is a plausible policy to address income inequality according to the study materials?

Accepted Answer

Increasing government transfers to low-income households

Question 8

In the context of endogenous growth theory, which factor is considered non-rivalrous and does not exhibit diminishing returns?

Accepted Answer

Education and human capital

Question 9

Suppose a country increases its investment in education, leading to higher human capital ($$H). $$According to the endogenous growth model, what is the likely effect on output ($$Y$$)?

Accepted Answer

Output ($$Y) $$will increase due to higher productivity and non-diminishing returns to education

Question 10

Which formula best describes the per capita consumption in the Solow model?

Accepted Answer

$$c^* = z f(k^*) - (n + d) k^*$$

Question 11

A country with a high savings rate but low technological progress is likely to experience which outcome in the long run?

Accepted Answer

High capital accumulation but limited growth in output per worker

Question 12

In the Solow model, what is the effect of an increase in the depreciation rate ($$d) on $$the steady-state capital per worker ($$k^*$$)?

Accepted Answer

Steady-state capital per worker ($$k^*) $$decreases

Question 13

Which of the following best explains why low-income consumers may not maximize welfare according to the study materials?

Accepted Answer

They purchase necessity goods and do not save, limiting their consumption possibilities

Question 14

In the Solow model, what is the relationship between the marginal product of capital ($$MPK) $$and the steady-state capital per worker ($$k^*$$)?

Accepted Answer

$$MPK = n + d at $$the Golden Rule steady-state

Question 15

Which scenario best illustrates dynamic inefficiency in the Solow model?

Accepted Answer

An increase in capital per worker ($$k) $$that leads to a decrease in consumption per worker ($$c)$$

Question 16

Which of the following is a key assumption in the endogenous growth model regarding education?

Accepted Answer

Education is non-rivalrous and does not exhibit diminishing returns

Question 17

If the marginal product of capital ($$MPK) is $$less than the sum of the population growth rate and depreciation rate ($$n + d$$), what should a country do to maximize consumption per worker?

Accepted Answer

Reduce capital per worker ($$k) to $$reach the Golden Rule level

Question 18

Which of the following best describes the effect of income inequality on economic activity according to the study materials?

Accepted Answer

Income inequality limits demand for goods and services, constraining production

Question 19

In the Solow model, what is the effect of an increase in the population growth rate ($$n) on $$the steady-state capital per worker ($$k^*$$)?

Accepted Answer

Steady-state capital per worker ($$k^*) $$decreases

Question 20

Which equation represents the consumer's problem in the Solow model?

Accepted Answer

$$\max c^* = z f(k^*) - (n + d) k^*$$ with respect to s$
