What Is Advertising Elasticity of Demand (AED)?
What Is Advertising Elasticity of Demand (AED)?
AED measures a market’s sensitivity to increases or decreases in advertising saturation. Advertising elasticity shows a campaign’s effectiveness in generating sales.
AED is calculated by dividing the percentage change in the quantity demanded by the percentage change in advertising expenditures. A positive advertising elasticity indicates increased advertising raises demand for the goods or services.
Key Takeaways
- Advertising elasticity of demand (AED) measures advertising expenditure’s impact on generating new sales for a company.
- A positive AED indicates advertising efforts increase demand for goods and services.
- AED does not consider other factors that affect demand, such as changes in consumer tastes, pricing, and spending habits.
AED Formula
Companies use their advertising-to-sales ratio to measure the effectiveness of their advertising strategies. Quality advertising can result in a shift in demand for a product or service. Advertising elasticity of demand quantifies the change in demand, expressed as a percentage, of spending on advertising in a given segment.
AED can show how successful a 1% increase in advertising dollars raises sales in a sector when all other factors are the same. Companies assess several periods of quantity demanded and advertising expenses to calculate AED. Advertising expenses are generally listed under operating expenses on an income statement, and companies use changes in demand estimates or rough sales figures in the calculation.
AED = % Change in Quantity Demanded ÷ % Change In Advertising Spending
Limitations of AED
Outside factors, such as the state of the economy and consumer tastes, may also affect demand for goods and services, so advertising cannot be the sole indicator. Many confuse AED with showing how advertising dollars affected sales, but sales aren’t part of the equation.
Demand and sales are two different metrics—sales are what was purchased, whereas demand is what is desired. It is difficult to measure demand, thus the change in sales is commonly used to replace the change in demand, often skewing the AED intention.
Luxury goods have a positive income elasticity of demand. As a consumer’s income rises, the demand for luxury goods may increase. An accurate AED for luxury items such as an expensive car or jewelry may be difficult to quantify.
AED vs. Price Elasticity of Demand (PED)
While advertising elasticity of demand measures how advertising impacts the demand for products or services, price elasticity of demand (PED) measures how price changes affect demand. Demand response to price fluctuations can be deemed elastic or inelastic depending on the consumer’s reaction.
Suppose the price of a product increases significantly, but consumers continue to buy the product at the same level. The price elasticity of demand is deemed as low or inelastic. Basic goods such as food or prescription drugs, are products with low or inelastic demand.
Conversely, a price increase decreases consumer demand if a product has a high PED. Consumers shift their purchases to substitute products at a lower price or forego the item. This occurs with optional or discretionary purchases.
Companies that sell goods or services with a high PED may find it challenging to increase sales by raising advertising expenditures. In such cases, trying to achieve a positive AED may be ineffective if the company doesn’t address the high price point driving consumers away.
What Is an Advertising Campaign?
Advertising can increase awareness of a product or service, increasing sales. Advertising is part of a company’s marketing strategy that commonly focuses on the four Ps: product, price, place, and promotion.
How Much Money Is Spent on Advertising?
Advertising may include print, television, mobile or digital ads. In 2023, U.S. companies spent nearly $856 billion on advertising.
Does Advertising Cause a Shift in Demand?
Advertising creates awareness and can generate more sales, but doesn’t independently affect demand. Demand also depends on consumer preferences, prices, income, and supply.
The Bottom Line
Advertising elasticity of demand is a measurement that helps demonstrate the effect advertising has on a good or service. However, many variables affect a marketing campaign’s success, such as a consumer’s income or price changes.
