# What are the Dorfman Steiner conditions?

## What are the Dorfman Steiner conditions?

Dorfman-Steiner Condition: For a profit-maximizing monopolist, the advertising-to-sales ratio is equal to the ratio of the elasticity of demand with respect to advertising relative to the elasticity of demand with respect to price.

What is optimal level of advertising?

The optimal level of advertising outlay is ascertained at the level of at which marginal contribution to profit MPC of advertising outlay parities to the marginal cost of advertising MCA. Therefore, at the maximum level of advertising outlay, MPC = MCA.

How do you calculate advertising elasticity of demand?

Advertising elasticity is a measure of an advertising campaign’s effectiveness in generating new sales. It is calculated by dividing the percentage change in the quantity demanded by the percentage change in advertising expenditures.

### How does advertising affect elasticity of demand?

The advertising elasticity of demand refers to how advertising a product can affect the quantity sold, according to the book “Managerial Economics,” by Arun Kumar and Rachana Sharma. In other words, increasing consumer demand through advertising can cancel out a decrease in consumer demand due to a price increase.

What is the optimal advertising to sales ratio?

It is important to note that there is no ideal advertising to sales ratio – it depends on the industry. For example, for retail goods such as clothing or perfume, the ratio can be as high as 10%, while paper and paper products can show a ratio as low as 0%.

What role does advertising play in oligopoly?

Advertisement in oligopoly markets is somewhat different than the other markets. The major benefit they reap from advertisements is that it helps them increase their overall market share and can also influence the demand of their product and cause it to rise.

## What is a good advertising elasticity of demand?

A value of greater than 1 indicates that the demand for the product is highly responsive to changes in advertising expenditure. This means that an increase in advertising expenditure will generate a greater increase in demand for the product.

What are the types of advertising elasticity of demand?

Relatively Inelastic Demand (EA<1)

Value of Elasticity Type / Description Meaning
EA>1 Elastic % change in demand/sales is higher than the % change in advertisement expenditure.
EA=1 Unitary Both are equal
EA<1 Inelastic % change in demand/sales is lower than % change in advertisement expenditure.

Does advertising decrease elasticity?

These studies suggest that allowing advertising increases the price elasticity of demand, thus lowering price in equilibrium.

### Will advertising lead to an increase in quantity demanded?

Advertising plays an important role in increasing and decreasing demand for a product or service. It’s a way to engage consumers and educate them about the business, product or service and results. If the advertising is targeting the audience segment correctly, then the effects on demand will likely be positive.

What is a good marketing ratio?

A good marketing ROI is 5:1. A ratio over 5:1 is considered strong for most businesses, and a 10:1 ratio is exceptional. Achieving a ratio higher than 10:1 ratio is possible, but it shouldn’t be the expectation. Your target ratio is largely dependent on your cost structure and will vary depending on your industry.
