The equilibrium price of coffee mugs rose sharply last month, but the equilibrium quantity was the same as ever. Three people tried to explain the situation. Which explanations could be right? Explain your logic. Ali: Demand increased, but supply was totally inelastic. Khan: Supply increased, but so did demand. Rabia: Supply decreased, but demand was totally inelastic.

a)When John can sell totem poles for 1,800 each, he markets 60 annually. when the price falls to $600 each, he is willing to sell only 24 each year. What is his price elasticity of supply ?  b) government pays attention to the elasticity of demand when selecting foods and services upon which to levy excise taxes. Assume a $1.00 tax is levied on some good and 10,000 units are sold. What is the tax revenue collected ?

Macmillan Learning Consider two markets: the market for coffee and the market for hot cocoa. The initial equilibrium for both markets is the same, the equilibrium price is $4.50, and the equilibrium quantity is 35.0. When the price is $12.75, the quantity supplied of coffee is 71.0 and the quantity supplied of hot cocoa 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 hot cocoa. Please round to two decimal places. Incorrect Supply in the market for coffee is less elastic than supply in the market for hot cocoa.

Consider two markets: the market for waffles and the market for pancakes. The initial equilibrium for both markets is the same, the equilibrium price is $6.50, and the equilibrium quantity is 35.0. When the price is $9.75, the quantity supplied of waffles is 57.0 and the quantity supplied of pancakes is 101.0. For simplicity of analysis, the demand for both goods is the same. Using the midpoint formula, calculate the elasticity of supply for pancakes. Please round to two decimal places. Supply in the market for waffles is

The income elasticity of demand of good B, is as follows: Good B: 0.2 If income rises by 5 %. By how much the quantity demanded of B will change?

New iPhones are normal goods. What will happen to the equilibrium price and quantity in the market for iPhones if the price of Android phones rises, the wages for iPhone chip makers increase, more buyers enter the market for iPhones, and the price of iPhone batteries increase? quantity will rise and the effect on price is ambiguous. quantity will fall and the effect on price is ambiguous. price will rise and the effect on quantity is ambiguous. price will fall and the effect on quantity is ambiguous.

Which of the following will produce a price increase for Good X? For each case, plot a chart with supply and demand curves to show your idea. Demand rises while Supply falls. Demand falls while Supply is constant. Supply falls while Demand is constant. Demand falls faster than Supply falls. Supply rises while Demand falls. Demand rises faster than Supply rises.

Suppose that the price elasticity of demand for a packet of cigar is -0.85 and the price elasticity of supply is 1.5 at market equilibrium. As a result of an increase on sales tax, the new equilibrium price rises by 15%. (a) What is the percentage change in quantity demanded of cigar? Show your calculation.

How would [1] a decrease in the price of flour and [2] an improvement in technology of pizza making would affect the market price and quantity of pizza, other things remaining constant? The price of pizza would drop and the equilibrium quantity would rise. The price of pizza would drop but the impact on the equilibrium quantity is uncertain. The equilibrium quantity of pizza would rise but the impact on price is uncertain. Both the price as well as the equilibrium quantity of pizza would rise.

Suppose you are modeling the market for puzzles. Based on the determinant change listed below, determine what happens to the equilibrium price and equilibrium quantity for each scenario. Card games, a replacement for puzzles, become cheaper. Equilibrium Price Increase: Equilibrium Quantity Decrease Equilibrium Price Decrease: Equilibrium Quantity Increase Equilibrium Price Increase; Equilibrium Quantity Increase Equilibrium Price Decrease; Equilibrium Quantity Decrease Equilibrium Price change is indeterminate: Equilibrium Quantity change is indeterminate OOO
