9. Application: Elasticity and hotel rooms The following graph input tool shows the daily demand for hotel rooms at the Peacock Hotel and Casino in Las Vegas, Nevada. To help the hotel management better understand the market, an economist identified three primary factors that affect the demand for rooms each night. These demand factors, along with the values corresponding to the initial demand curve, are shown in the following table and alongside the graph input tool. Demand Factor Initial Value Average American household income $40,000 per year Roundtrip airfare from New York (JFK) to Las Vegas (LAS) $200 per roundtrip Room rate at the Grandiose Hotel and Casino, which is near the Peacock $250 per night   Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph. Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly. 050100150200250300350400450500500450400350300250200150100500PRICE (Dollars per room)QUANTITY (Hotel rooms)Demand   Graph Input Tool   Market for Peacock's Hotel Rooms       Price (Dollars per room)         Quantity Demanded (Hotel rooms per night)         Demand Factors       Average Income (Thousands of dollars)           Airfare from JFK to LAS (Dollars per roundtrip)           Room Rate at Grandiose (Dollars per night)             For each of the following scenarios, begin by assuming that all demand factors are set to their original values and Peacock is charging $350 per room per night. If average household income increases by 50%, from $40,000 to $60,000 per year, the quantity of rooms demanded at the Peacock    from   rooms per night to   rooms per night. Therefore, the income elasticity of demand is    , meaning that hotel rooms at the Peacock are    .   If the price of a room at the Grandiose were to decrease by 10%, from $250 to $225, while all other demand factors remain at their initial values, the quantity of rooms demanded at the Peacock    from   rooms per night to   rooms per night. Because the cross-price elasticity of demand is    , hotel rooms at the Peacock and hotel rooms at the Grandiose are    .   Peacock is debating decreasing the price of its rooms to $325 per night. Under the initial demand conditions, you can see that this would cause its total revenue to    . Decreasing the price will always have this effect on revenue when Peacock is operating on the    portion of its demand curve.

QUESTION 1 Encyclopedias were widely used back in the 1970s. Most students and scholars used the encyclopedia to find information on various topics. There was only a small percentage decrease in quantity demanded for encyclopedias in the 1970s when there was a relatively larger percentage increase in price. Today, in the age of the internet, a small percentage increase in price of encyclopedias results in a relatively larger percentage decrease in the quantity demanded. 1. The price elasticiy of demand for encyclopedias in the 1970s was relatively less elastic than today. 2. If the price for encyclopedias increased in the 1970s, the point price elasticity of demand for encyclopedias woud have been greater than 1. 3. The price elasticity of demand for encyclopedias, after the internet, is considered elastic. Which of the above statements are true? O Only 1 is true. O Only 2 is true. Only 3 is true. Both 1 and 2 are true. Both 1 and 3 are true.

9. Application: Elasticity and hotel rooms The following graph input tool shows the daily demand for hotel rooms at the Rivers Hotel and Casino in Atlantic City, New Jersey. To help the hotel management better understand the market, an economist identified three primary factors that affect the demand for rooms each night. These demand factors, along with the values corresponding to the initial demand curve, are shown in the following table and alongside the graph input tool. Demand Factor Average American household income Roundtrip airfare from New Orleans (MSY) to Atlantic City (ACY) Room rate at the Continental Hotel and Casino, which is near the Rivers Initial Value $40,000 per year Bookmark this tab poundtrip $250 per night Use the graph input tool to help you answer the following questions.

Suppose that your demand schedule for books is as follows: (PHOTO) (SHOW FORMULAS, STEP BY STEP PROCEDURE) Use the midpoint method to calculate your price elasticity of demand as the price of books increases from $10 to $12 if your income is $10,000. Is it elastic or inelastic? Explain. Use the midpoint method to calculate your price elasticity of demand as the price of books increases from $10 to $12 if your income is $12,000. Is it elastic or inelastic? Explain. Calculate your income elasticity of demand as your income increases from $10,000 to 12,000 if the price is $14. Calculate your income elasticity of demand as your income increases from $10,000 to 12,000 if the price is $8.
