The price of coffee rose sharply last month, while the quantity sold remained the same. Five people suggest various explanations: Leonard: Demand increased, but supply was perfectly inelastic. Sheldon: Demand increased, but it was perfectly inelastic. Penny: Demand increased, but supply decreased at the same time. Howard: Supply decreased, but demand was unit elastic. Raj: Supply decreased, but demand was perfectly inelastic. Who could possibly be right? Use graphs to explain your answer.

Consider two markets: the market for cat food and the market for dog food. The initial equilibrium for both markets is the same, the equilibrium price is $4.50, and the equilibrium quantity is 31.0. When the price is $8.75, the quantity supplied of cat food is 75.0 and the quantity supplied of dog food is 105.0. For simplicity of analysis, the demand for both goods is the same. Using the midpoint formula, calculate the elasticity of supply for dog food. Please round to two decimal places.

Does this imply that ice cream and frozen yogurt are complements or substitutes and does that answer match your intuition for whether or not ice cream and frozen yogurt are complements or substitutes? If not, how can you account for the value of the cross price elasticity implied by the data?

In 1998, five companies were found guilty because of their actions to raise the price of an animal feed additive, lysine, by limiting its supply. Explain why they would engage such a practice with the use of a graph. Assume that the demand for lysine is inelastic in the short term.

Explain all options, please.

The demand for hamburgers is given by Qd=10-p and the supply is Qs=4p-10, where pd and ps are, respectively the price paid by demanders and the price received by suppliers. A: Draw the demand and supply functions. What is the price-elasticity of demand? What is the price-elasticity of supply? B: Find the equilibrium quantity and price, and show them on the graph. C: Suppose due to the rising health awareness the demand decreases to Q d=5-p. Find the new equilibrium prices and quantity, and show them on the graph.  D: Suppose that the demand and supply are as before, i.e. Qd=10-p and Qs=4p-10, but now the government imposes a quantity tax on the suppler at the rate of 1 per unit of the quantity. What quantity will be sold and what price? E: In part d), what is the total amount of tax collected by the government? How this tax amount is divided between the demanders and supplier? Who pays more and why? Explain

Consider two markets: the market for cat food and the market for dog food. The initial equilibrium for both markets is the same, the equilibrium price is $⁢3.50, and the equilibrium quantity is 31.0. When the price is $10.75, the quantity supplied of cat food is 75.0 and the quantity supplied of dog food is 103.0. For simplicity of analysis, the demand for both goods is the same. Using the midpoint formula, calculate the elasticity of supply for dog food. Please round to two decimal places.
