Money Demand and Economic Models

The video discusses the concept of price stickiness and its impact on monetary policy. It contrasts the classical model, which assumes complete price flexibility, with the Keynesian model, which assumes price stickiness in the short run. The classical model suggests that monetary policy is ineffective due to flexible prices, while the Keynesian model shows that monetary policy can influence short-term interest rates due to sticky prices. However, in the long run, monetary policy may lead to inflation without affecting long-term interest rates.

What is the primary assumption about prices in the classical economic model?

• Prices are sticky in the short run.

• Prices are determined by consumer demand.

• Prices are completely flexible.

• Prices are fixed by the government.

How does an increase in money supply affect price levels according to the classical model?

• Price levels decrease.

• Price levels remain constant.

• Price levels increase.

• Price levels fluctuate randomly.

In the classical model, what happens to money demand when price levels rise?

• Money demand decreases.

• Money demand remains unchanged.

• Money demand increases.

• Money demand becomes unpredictable.

Why is it considered unwise to rely on the classical model in the short run?

• Because it only applies to long-term scenarios.

• Because it ignores consumer behavior.

• Because it does not account for government intervention.

• Because it assumes complete price flexibility, which is unrealistic.

What is the key assumption of the Keynesian model regarding prices?

• Prices are completely flexible.

• Prices are sticky in the short run.

• Prices are set by central banks.

• Prices are determined by international markets.

In the Keynesian model, what happens to interest rates when the money supply increases?

• Interest rates increase.

• Interest rates decrease.

• Interest rates remain constant.

• Interest rates become volatile.

Why does the increase in money supply not trigger an increase in price levels in the short run in the Keynesian model?

• Because international trade balances it out.

• Because the government controls prices.

• Because prices are sticky in the short run.

• Because consumer demand decreases.

What happens to money demand in the long run when prices become less sticky?

• Money demand decreases.

• Money demand remains unchanged.

• Money demand increases.

• Money demand becomes irrelevant.

What is a limitation of monetary policy in the long run according to the discussion?

• It can stabilize the economy permanently.

• It can only affect short-term interest rates.

• It has no impact on inflation.

• It can control long-term interest rates.

What is one argument against the effectiveness of monetary policy?

• It can lead to deflation.

• It only affects short-term interest rates and contributes to inflation.

• It stabilizes the economy too quickly.

• It is too complex for practical use.
