Microeconomics Test #3
Which would benefit a taxpayer more: A $1,000 tax credit or a $5,000 tax deduction? Assume the taxpayer is in the 35% tax bracket (her marginal tax rate is 35%) and calculate the reduction in her tax liability in either case.
$5,000 Tax Deduction
Imagine your friend, Sally, operates an apple orchard where she grows "honey dew" apples. Assume that the industry is perfectly competitive. She discovers that she can increase her production of apples by 500 pounds per year if she plants an additional acre of trees. It will cost her an additional $1,000 per year to manage this extra acre. Planting the additional acre will increase her annual profits if the price of apples is:
. Any price greater than $2.00 per pound
Firms in monopolistically-competitive industries can increase profits in the short run by:
. Differentiating their products
Which of the following taxes are proportional?
. Indiana state income tax
The long-run profit squeeze tends to reduce economic profits to zero in perfectly competitive industries due to:
. The free entry and exit of competing firms
Based on the recent US data presented in class
. The real growth rate of an economy (g) equals 2-3%, while the real return on investment in capital (r) equals 7-8%
Suppose an industry consists of 7 firms. One has 25% market share, another has 18% market share, a third has 15%, a fourth has 12% and the remaining three have 10% market share each. The four-firm concentration ratio is:
70
Oligopoly
A market structure in which a few large firms dominate a market
What can a firm that operates in a monopolistically competitive market do to increase its profit?
Advertise the distinctiveness of its product
Amy: P=$2.00 Amy: P=$2.25 Zack: P=$2.00 $9,000, $9,000 $17,000, $5,000 Zack: P=$2.25 $5,000, $17,000 $15,000, $15,000 What is Amy's "dominant strategy" in this case? Explain, using profit figures from the table above.
Amy chooses the low price ($2.00) regardless of what Zack chooses: o Amy's profit = $9,000 (> $5,000) if Zack chooses the low price ($2.00) o Amy's profit = $17,000 (> $15,000) if Zack chooses high price ($2.25)
In a perfectly-competitive industry, profit is measured by comparing price to:
Average Cost

Divergence occurs
"A $10,000 income tax deduction reduces a taxpayer's income tax liability by $10,000"
False
Which of the following taxes are progressive?
Federal income tax
What are the three characteristics of an oligopoly?
Few firms, differentiated product (or sometimes identical), and high barriers to entry
consider the six ethical frameworks suggested by Jeffrey Sachs in his book, The Age of Sustainable Development (2015) and presented in class. Which of the six ethical frameworks do you find most helpful when thinking about the distribution of income and wealth. Why?
I would choose human rights because everyone has the right to have a standard life but the people who is rich they will always be like that. At the same time, poor people can use this right to demand a better life than the one they have. Maybe they won't be rich but they will have a place to eat and live.
Based on your answers to Questions 1 and 2 above, is the federal income tax progressive, proportional or regressive? Explain, including average tax rate calculations in your response.
If income = $18,000 Average tax rate = $1,962.50/18,000 = 0.1090278 = 11% The $18,000 income earner pays only 11% of income in taxes If income = $90,000 Average tax rate = $15,679.50/$90,000 = 0.1742167 = 17% The $90,000 income earner pays 17% of income in taxes The federal income tax is progressive, since the average tax rate is higher for higher income earners
In 2019 the highest quintile earned 51.9% of U.S. household income while the lowest quintile earned 3.1%. In your opinion, should U.S. household incomes be distributed more equally than this, less equally than this or about the same as they are? Provide a compelling reason for your opinion.
In my opinion I think that the people who most support the community should receive more money such as doctors, teachers, etc. We should stop giving so much money to people who already have and start giving to people who do not have the same luck since many young people want to study at school but do not have enough money to pay for their studies. Teachers should also receive more money since they are a great contribution to our community.
Based on analysis presented in class from the Congressional Budget Office (CBO) and Bloomberg Economics, the 2017 Tax Reform will:
Increase the federal deficit by reducing government tax receipts
If a perfectly-competitive firm discovers that the marginal revenue earned from selling one additional unit is significantly more than the marginal cost of producing that unit, it can increase its profit by:
Increasing the output level by at least one unit
Based on a Harvard study, the video showed American's perception of the wealth distribution, and contrasted this to what is actually the case as well as what they thought would be ideal. According to the video, the actual US wealth distribution is:
Less equally distributed than what people perceive, and even less equally distributed than what people would consider ideal

The "dominant strategy" in the one-time pricing scenario ("prisoner's dilemma") explains why:
Oligopolists tend not to collude with each other

calculate the federal income tax liability (taxes paid) in 2020 for a single individual earning $90,000 in taxable income. Write down the exact number, rounded to the nearest cent. Do not include the dollar sign nor other punctuation or words.
Tax liability = ($9,875)(0.10) + ($40,125 - $9,875)(0.12) + ($85,525 - $40,125)(0.22) + ($90,000 - $85,525)(0.24) = = $987.50 + $3,630 + $9,988 + $1,074 = = $15,679.50 The correct answer is: 15679.5

Was this video helpful to you in understanding the distribution of wealth globally? If yes, why? If not, why not
Yes, because it shows clearly how the rich people always gets richer and poor people will be poorer. It really shows the reality of whats happening with the wealth of the world. Big corporations always gets billions and billions of dollars

Calculate the federal income tax liability (taxes paid) in 2020 for a single individual earning $18,000 in taxable income. Write down the exact number, rounded to the nearest cent. Do not include the dollar sign nor other punctuation or words.
tax liability = ($9,875)(0.10) + ($18,000 - $9,875)(0.12) = = $987.50 + $975.00 = $1,962.50 The correct answer is: 1962.5
