What does the Solow growth model primarily focus on?

• Consumer behavior

• Government policies

• Supply-side factors

• Demand-side factors

Answer explanation

The Solow growth model primarily focuses on supply-side factors, such as capital accumulation, labor force growth, and technological progress, which drive long-term economic growth.

In the Solow model, which factor is assumed to have non-diminishing marginal returns?

• Human capital

• Technology

• Capital

• Labour

Answer explanation

In the Solow model, technology is assumed to have non-diminishing marginal returns, meaning it can continuously enhance productivity without diminishing effects, unlike capital, labor, and human capital which face diminishing returns.

What is the production function in the Solow growth model?

• Y = f(N; K; A)

• Y = f(N; K; H; A)

• Y = f(N; H)

• Y = f(K; A)

Answer explanation

In the Solow growth model, the production function is represented as Y = f(N; K; A), where Y is output, N is labor, K is capital, and A is technology. This captures the essential inputs for economic growth.

What happens to output (Y) when capital (K) or labor (N) increases according to the Solow model?

• Remains constant

• Decreases

• Increases at a diminishing rate

• Increases indefinitely

Answer explanation

According to the Solow model, as capital (K) or labor (N) increases, output (Y) increases at a diminishing rate due to the principle of diminishing returns. This means each additional unit of input contributes less to output.

What is the definition of balanced growth according to the text?

• Constant growth in population

• Constant growth in K/N

• Constant growth in Y/N

• Constant growth in savings

Answer explanation

Balanced growth is defined as constant growth in output per worker (Y/N), which indicates that productivity is increasing at a steady rate, ensuring economic stability and efficiency.
