Demand function specifies other factors that management will often consider, including the design and packaging of products, the amount and distribution of the firm’s advertising budget, the size of the sales force, promotional expenditures, the time period of adjustment for any price changes, and taxes or subsidies. For this discussion forum, consider your favorite consumer product (e.g. cell phone, car, cereal, restaurant, hair gel, etc.) and describe the variables that might be part of the demand function (i.e. substitute good, complementary good, income level, advertisement, consumer preference, etc.) for this product. How would you describe the elasticity of demand for this product – is it highly or somewhat elastic or inelastic? Why?
