Final Answer:
Nominal spending rose 0.8% in September due to a surge in spending on automobiles (a), consumers receiving $3,400 in stimulus checks during the last 18 months (b), and low debt burdens (d). However, a strong wealth effect is not a factor influencing the nominal spending increase. The correct answer is c) A strong wealth effect.
Step-by-step explanation:
Nominal spending (NS) can be influenced by various factors. Let's break down the given options:
a) Surge in spending on automobiles: An increase in spending on automobiles contributes to the rise in nominal spending. This implies that NS = NS₀ + ∆Spending on Automobiles, where NS₀ is the initial nominal spending.
b) Consumers received $3,400 in stimulus checks during the last 18 months: The receipt of stimulus checks injects additional funds into the economy, causing a boost in nominal spending. This can be expressed as NS = NS₀ + Stimulus Checks.
c) A strong wealth effect: A strong wealth effect can impact consumer confidence and spending habits. If individuals feel wealthier due to factors like rising asset values, they are likely to spend more. Therefore, NS = NS₀ + Wealth Effect.
d) Low debt burdens: Lower debt burdens can free up disposable income, leading to increased spending. This translates to NS = NS₀ + ∆Disposable Income from Lower Debt.
Given that NS rose by 0.8%, all factors except the strong wealth effect directly contribute to this increase. Therefore, option c is the correct answer. In summary, while factors a, b, and d contribute to the rise in nominal spending, a strong wealth effect does not play a role in this specific increase.
