Effective Demand

Definition

Effective demand represents the demand for a good or service that is not only desired but also backed by the financial capacity of consumers to buy it at the current market price. This differs from notional demand, which includes all consumer desires regardless of purchasing power.

For a practical example:

Example: In the U.S., the effective demand for new housing units over one year might be 1 million units. Although 10 million families may want to buy new homes, only 1 million can afford to do so, considering current construction and real estate market costs.

Examples

Automobile Market: In the automotive sector, 3 million consumers may aspire to buy electric vehicles (EVs), but if only 1 million have the financial resources to purchase an EV at current prices, the effective demand for EVs would be 1 million units.
Luxury Goods: While millions may desire luxury watches, the effective demand would only account for those who can afford and intend to buy such expensive items.

Frequently Asked Questions (FAQ)

What is the difference between effective demand and notional demand?

Effective demand includes the willingness and ability to pay for a good or service at the current price. Notional demand, on the other hand, reflects a desire or wish to buy without considering affordability.

Why is effective demand important in real estate?

Effective demand helps developers, investors, and policymakers understand the realistic consumer base that can afford and will likely purchase properties. This aids in better planning and resource allocation.

How can effective demand influence market pricing?

If effective demand is high, prices may increase due to greater willingness and ability to pay. Conversely, if effective demand is low, prices may decline to stimulate consumer interest and sales.

How is effective demand measured?

Effective demand is measured by analyzing consumer income levels, current market prices, economic conditions, and purchasing intentions to determine who can afford and intends to purchase the good or service.

Can effective demand shift over time?

Yes, effective demand can shift due to changes in income levels, consumer preferences, economic policies, and market prices.

Demand Elasticity: A measure of how quantity demanded changes in response to a price change.
Aggregate Demand: The total demand for goods and services within an economy, often assessed over a specific period.
Supply and Demand: Fundamental economic concepts that describe the relationship between the availability of a product and the desire for that product.
Market Equilibrium: The state where supply equals demand, determining the market price and quantity of goods sold.
