2. Price-discriminating firms charge higher prices to those who

• have greater incomes.

• have higher price elasticities of demand compared to others.

• have more inelastic demand.

• have many substitutes available to them.

• 3. Two customers, Fred and Lamont, walk into a Grady’s Used Pickups. Who probably has a more inelastic demand for one of Grady’s pickups: people like Lamont, who are good at shopping around, or people like Fred, who know what they like and just buy it?

• People like Fred

• People like Lamont

• 4. Where will you see more price discrimination: In monopoly-type markets with just a few firms or in competitive markets with many firms?

• Competitive markets

• Monopoly-type markets

• 5. Consider two groups of people who shop at the same Wal-Mart: the Convenience Shoppers and the Bargain Shoppers. Which of the following statements is most likely to be true?

• Wal-Mart is more likely to have monopoly power over Bargain Shoppers because this group is more likely to splurge on something on a whim rather than stick to their prearranged shopping list.

• Wal-Mart is more likely to have monopoly power over Bargain Shoppers because this group is more likely to stick to their prearranged shopping list rather than splurging on something on a whim.

• Wal-Mart is more likely to have monopoly power over Convenience Shoppers because this group is more likely to stick to their prearranged shopping list rather than splurging on something on a whim.

• Wal-Mart is more likely to have monopoly power over Convenience Shoppers because this group is more likely to splurge on something on a whim rather than stick to their prearranged shopping list.

• 6. When will a monopoly create more output: When the government bans price discrimination or when the monopoly is allowed to and can perfectly price discriminate?

• Monopoly-type markets

• Competitive markets

A forklift will last for only 4 more years. It costs $6,100 a year to maintain. For $16,000 you can buy a new lift that can last for 9 years and should require maintenance costs of only $3,100 a year. a-1. Calculate the equivalent cost of owning and operating the forklift if the discount rate is 6% per year. (Do not round intermediate calculations. Round your answer to 2 decimal places.) a-2. Should you replace the forklift? b-1. Calculate the equivalent cost of owning and operating the forklift if the discount rate is 14% per year. (Do not round intermediate calculations. Round your answer to 2 decimal places.) b-2. Should you replace the forklift?

Python:

def factors(matrix, factor):

The matrix is a 3D list of integers.

factors are either one, two, or three

If the factor is 'one' it will return a the first value from each list

if the factor is 'two' it will return the second value, and same for the third.

Example;

input = [ [ [1, 2, 3], [3, 2, 9], [9, 8, 6] ],

[ [0, 0, 4], [8, 9, 0], [5, 2, 1] ],

[ [0, 1, 1], [5, 5, 9], [3, 8, 4] ] ], 'one')

output = [ [1, 3, 9], [0, 8, 5], [0, 5, 3] ]

1) Describe the general types of barriers.

2) Competition keeps prices lower for consumers. So why do we have patent laws?

3) What is the relationship between the marginal revenue curve and the demand curve for a single-price monopolist?

Q3. Hypothesis: Informing people about recycling causes them to recycle more.

Study design: 50 households were randomly assigned to a treatment group where they were

informed by letter about proper recycling habits and its benefit on environment, while 50

different households were randomly assigned to a control group that did not receive such a letter.

After 3 months, the weekly average recycling amount in the treatment group was 12.4 lbs (

sd

=

2.5), while the weekly average recycling amount in the control group was 3.7 lbs (

sd

= 1.1)

Lottery – Let $1,000 be your current wealth. There are 100 people and each buys a lottery ticket at $5. The administrative cost of the lottery ticket per person is $5. If you win the lottery, you will get $500. There is only one person who can win the lottery. (The cost is 5+5 not 5)

a. Define the gamble

b. Calculate the expected value of the gamble

c. Is this gamble favorable, fair, or unfavorable?

d. Now, suppose your utility function is ? = ?5/2 . Calculate the Certainty Equivalent and the risk premium for individual willing to buy the lottery (i.e., minimum amount of money he/she needs to receive to forgo the lottery)?.

e. Now suppose that there are only 50 individuals participating in the lottery. Without calculating all the math again, what happens to risk premium? Does it increase, decrease, or stay the same?
