Question 1

What happens to economic growth when an economy reaches steady state in the neoclassical model?

Accepted Answer

In steady state, the capital-labor ratio stabilizes, and output per worker stops increasing. Investment only replaces depreciated capital rather than adding new productive capacity. Real wages cease to grow because labor productivity plateaus, and the marginal product of capital stabilizes, eliminating gains from further capital accumulation.

Question 2

Why does the marginal benefit of adding more capital eventually decline?

Accepted Answer

Each additional machine or tool provides smaller productivity gains due to diminishing returns. Workers have limited capacity to use more equipment effectively. Eventually, one worker cannot productively utilize more capital, regardless of how much is available, causing the marginal product of capital to decrease and stabilize.

Question 3

How does the bakery example illustrate the concept of steady state?

Accepted Answer

A bakery initially grows by purchasing ovens, mixers, and equipment, increasing production and worker wages. Eventually, adding more ovens provides no benefit due to space constraints and insufficient staff. The bakery maintains current output but cannot expand further, demonstrating how steady state represents a plateau in growth despite continued investment.

Question 4

What role does exogenous technological progress play in the neoclassical growth model?

Accepted Answer

Exogenous technological progress is crucial for escaping steady state and sustaining long-run growth. Without it, economies plateau as capital accumulation alone cannot maintain expansion. Technology enters the model externally, allowing productivity improvements and continued wage growth beyond the steady-state equilibrium point.

Question 5

Why does the Solow model treat technology as exogenous rather than explaining its origins?

Accepted Answer

The Solow model assumes technology appears externally without explaining economic incentives driving research and innovation. This significant limitation inspired the creation of endogenous growth models, which attempt to explain how ideas are generated, spread, and sustained within the economy to drive long-run growth.

Question 6

What is the relationship between labor productivity and real wages in steady state?

Accepted Answer

Real wages are directly measured by labor productivity. When the economy reaches steady state at point V, labor productivity is maximized but stops increasing. Consequently, real wages also cease to grow, meaning workers' purchasing power remains constant despite continued economic activity.

Question 7

Does reaching steady state indicate economic failure or stagnation?

Accepted Answer

Steady state does not mean economic failure; it simply represents a point where additional capital no longer raises output per worker. The economy functions well and maintains current living standards. Without technological improvements or other changes enhancing productivity, living standards remain stable rather than declining.
