1.If demand is elastic, the difference between the monopolistic price and the competitive market price would be greater compared to when the elasticity is low. 2. In 2011, heavy rain and cold weather destroyed 10 percent of the world coffee products. Therefore, it is expected that people consume less coffee.

Question 2. Suppose that the price elasticity of demand for an ice cream cone is -1.9. If the local ice cream shop owner wants to increase total revenue, what would you recommend he or she do?

Consider the following pairs of goods. In each case, which would you expect to have the more elastic demand? Why? a. water or diamonds b. insulin or nasal decongestant spray c. food in general or breakfast cereal d. gasoline over the course of a week or gasoline over the course of a year e. personal computers or IBM personal computers

The IS-LM diagram on the right shows the initial equilibrium of a closed economy at point A. Now suppose that consumer confidence falls, inducing households to spend less and attempt to save more. In the IS-LM diagram, show the effect of the fall in consumer confidence on the equilibrium in the economy. 1.) Using the 3-point curve line drawing tool, show the effect of a fall in consumer confidence. Properly label your line. 2.) Using the point drawing tool, indicate the new equilibrium point. Label your point 'B'. Carefully follow the instructions above and only draw the required objects. Interest rate, i Output, Y (trillion dollars) LM₁ IS₁

1. As a transit planner for the city of Miami, you must predict how many people ride the Miami Metrorail and how much money is generated from train fares. According to a recent study, the short-run elasticity of demand for Metrorail is 0.62 and the long- run elasticity is 1.59. The current ridership is 50,000 people per day. Suppose the city commission decides to increase fares by 10%. Predict the changes in train ridership over a one-month period and a five-year period. ANS: b. Over the one-month period, will total revenue increase or decrease? What will happen in the five-year period? ANS

Suppose the accompanying table contains data on how many Veggie Delite sandwiches Subway is willing to sell each day at two different prices. Calculate the daily price elasticity of supply when the price increases from $5.00 to $7.50. Please round to the nearest hundredth. Price(per sandwich) Quantity supplied(sandwiches per day) $5.00 200,000 $7.50 210,000 a. Daily price elasticity of supply for Veggie Delite sandwiches = b. The daily price elasticity of supply for Veggie Delite sandwiches is relatively Elastic or Inelastic Now consider how responsive Subway’s supply of Veggie Delite sandwiches is to changes in price on an annual basis instead of a daily basis. c. Compared to the daily value, the annual price elasticity of supply for Veggie Delite sandwiches is likely to be more Inelastic or Elastic  and the annual supply curve is likely Flatter or Steeper  to be than the daily supply curve.

The market for Harvard hoodies in the campus store is in equilibrium. They currently sell 25 hoodies in a week at a price of $50 per hoodie 1. What is the current revenue? 2 if they decrease the price of the hoodies from $50 to $40 the quantity demanded would increase from 25 to 40 hoodies A. What is the new revenue B. Calculate the price of the elasticity of the hoodie demand at these changes in price and quantity. 3. Assuming the same elasticity of demand as you just calculated if they instead increase the price from $50 to $ 75 A. What would be the new quantity demanded B. What would be the new revenue
