Question

When the money supply increases, output rises before prices. Why?

Short answer

An increase in the money supply initially leads to lower interest rates, which stimulates spending and investment. This increases demand for goods and services, leading to an increase in output as firms respond. Over time, persistent excess demand leads firms to raise prices, but output changes quicker than prices, hence output rises before prices.

Step-by-step solution

The Impact of Increased Money Supply

Initially, when the money supply increases, there is more money available in the economy. This leads to decrease in the interest rate. Lower interest rates make borrowing cheaper and encourage consumers to spend and firms to invest which stimulates economic activity.

The Effect on Output

As a result of the increased spending and investment, demand for goods and services increases which leads firms to increase their output to meet the higher demand. This rise in output occurs before prices increase because firms first respond to the higher demand by increasing production.

The Delayed Effect on Prices

Over time, as demand continues to outpace supply, firms start to raise prices in response to the persistent excess demand. However, this process takes time as firms often adjust their output levels more quickly than their prices. This explains why output rises before prices when the money supply increases.

Key concepts

Understanding Output

Output refers to the total amount of goods and services produced in an economy. When we talk about output in the context of an increased money supply, we see that output tends to increase first because of the immediate reaction of firms to shifts in demand. - When people and businesses find it cheaper to borrow money, they tend to spend and invest more. - This increased spending means a higher demand for goods and services. - To meet this new demand, firms ramp up production, resulting in more output. The increase in output occurs before any significant price changes because adjusting production is often quicker than adjusting prices. Firms are usually eager to capture the new demand, thereby pushing up production levels swiftly.

Interest Rates Explained

Interest rates are the cost of borrowing money. When the money supply expands, interest rates often fall. This happens because there's more capital available for people and firms to borrow. Lower interest rates influence the economy in several ways:

• They make loans cheaper, enticing both consumers and businesses to take out more loans.
• Consumer spending increases as people can afford larger purchases due to lower borrowing costs.
• Businesses are more likely to invest in expansion, new projects, and equipment when borrowing is affordable.

These activities change the landscape of economic activity by stimulating sectors across the economy, setting off a chain reaction that impacts output positively.

Inflation and Its Delay

Inflation is when the general price level of goods and services rises. Although an increased money supply eventually leads to inflation, the effect is often delayed. Initially:

• Firms are more focused on meeting immediate demand by increasing output rather than raising prices.
• Price increases occur gradually because businesses first try to attract more customers through enhanced production.
• Over time, as demand consistently outstrips supply, prices eventually rise. This is known as demand-pull inflation.

Therefore, the delay in inflation is due to the lag in price adjustments compared to the quicker pace of output adjustments.

The Role of Economic Activity

Economic activity encompasses all the actions that serve to produce, distribute, and consume goods and services. The introduction of more money into the economy enhances economic activity by making funds more available. Several impacts are evident:

• An increase in money supply increases economic transactions, as businesses and consumers have more money to spend and invest.
• The knock-on effect means industries start to see more vibrancy as various sectors expand to meet new demand.
• With more spending power, companies might not only meet local demand but also grow their export markets.

This chain of reactions due to vibrant economic activity is pivotal in understanding why output levels rise prior to a marked increase in prices or inflation.
