Which of the following is a building block of neoclassical economics?
a) sticky wages and prices
b) wages and prices will adjust in a flexible manner
c) aggregate demand model
d) the size of the economy is determined by real GDP
The correct answer and explanation is :
The correct answer is b) wages and prices will adjust in a flexible manner.
Explanation:
Neoclassical economics is a school of thought that primarily focuses on the idea that markets are generally efficient, and that economic outcomes can be determined by the behavior of individuals making rational decisions. One of the central tenets of neoclassical economics is the flexibility of wages and prices. According to this theory, when there is a discrepancy between supply and demand in any given market, wages and prices will adjust in a way that returns the market to equilibrium.
This concept of flexible wages and prices is integral to the neoclassical model because it assumes that, in the long run, all markets—including labor, goods, and services—will always clear (i.e., supply will meet demand). For example, if there is excess unemployment, wages will decrease, making it cheaper for firms to hire workers, which leads to increased employment. Similarly, if there is excess supply in the product market, prices will fall, which restores demand and ensures that resources are allocated efficiently.
In contrast to Keynesian economics, which suggests that wages and prices may be “sticky” (i.e., not adjust quickly or fully), neoclassical economics posits that prices and wages are flexible and adjust rapidly to restore equilibrium. This leads to the conclusion that the economy operates at full employment in the long run, and that external interventions (such as government stimulus) are unnecessary because markets will self-correct.
To briefly touch on the other options:
- a) sticky wages and prices refers to a concept more aligned with Keynesian economics, which asserts that wages and prices may not adjust quickly in the short run.
- c) aggregate demand model is part of Keynesian economics, which emphasizes the role of government intervention in stabilizing the economy through demand-side policies.
- d) the size of the economy is determined by real GDP is a more general statement that is not specific to neoclassical economics, as it doesn’t focus on the mechanism of market adjustment, which is central to the theory.
