Summary
Demand estimation is a key part of business and economics. Students learn how to use demand equations to predict sales and make decisions.
Demand Equation for Bacfree
A demand equation for water filters is given. Students learn to test if each factor in the equation affects sales. They also learn to check if the equation fits economic theory.
Revenue and Elasticity
Students derive the total, average and marginal revenue functions. They also calculate different types of elasticity. This helps them understand how changes in price, income, advertising, and competitor's price affect demand.
Demand Equation for Wonderful Tiles
A demand equation for ceramic tiles is given. Students evaluate the equation's overall fit. They also determine the demand curve function and decide if the company should change its price to increase revenue.
Key terms
- Demand equation
- An equation that shows how quantity demanded depends on other factors.
- t-test
- A test to see if a factor in the demand equation significantly affects quantity demanded.
- R-squared
- A measure of how well the demand equation explains changes in quantity demanded.
- Elasticity
- A measure of how much quantity demanded changes in response to a change in price, income, advertising, or competitor's price.
- Total revenue function
- An equation that shows how total revenue depends on quantity sold and price.
- Confidence interval
- A range within which the actual value is expected to lie, with a certain level of confidence.
