A firm has estimated the following demand function for its product: Q = 8 - 2P + 0.101I + A where Q is quantity demanded per month in thousands, P is the product price, I is an index of consumer income, and A is advertising expenditures per month in thousands. Assume that P = $10, I = 120, and A = 10. Based on this information, calculate values for quantity demanded, price elasticity of demand, income elasticity of demand, and advertising elasticity. (Use the point formulas to complete the required elasticity calculations).
The market supply and demand functions for a product traded on a perfectly competitive market are given below: QD = 40-P QS = -5 +4P. Based on this information, calculate the equilibrium price and quantity in this market.
