Econ 102 Review 10/01/2013 Inferior Good: is a good that decreases in demand when consumer income rises, unlike normal goods, for  which the opposite is observed. Normal goods are those for which consumers' demand increases when  their income increases. .. The going rent in the market for I­bedroom apartments in your neighborhood is $800. If the government  imposes a price ceiling of $400 in the market: A) More people will be willing to rent apartments at every price B) Less people will rent apartments. C) The same number of apartments will be rented D) More people will rent apartments Answer is B. Less people will supply apartments at this price Equilibrium in the market for peanut butter is disturbed by an increase in the price of peanuts. Producer  surplus in the peanut butter market: A) will decrease B) will increase C) May change, but we cannot determine the change without more information D) Will not change Prices increase because either demand increases (which would increase producer surplus) or supply  decreases (which would raise price but lower overall surplus) What determines whether there is an increase in total surplus is if the sales increase. The more quantity the  more surplus If total surplus falls, which of the following must have occurred? A) There was an increase in demand and an increase in supply B) There was an increase in demand or a decrease in supply C) There was a decrease in demand or a decrease in supply D) There was a decrease in demand and an increase in supply If both supply and demand decrease, quantity decreases, thus C is correct answer! 1.Mountain River Adventures offers whitewater­rafting trips down the Colorado River. IT costs the firm $100  for the first raft trip per day, $120 for the second, $140 for the third, and $160 for the fourth. If the market  price for a raft trop was $120 but has now increased to $150, the gain in producer surplus is equal to answer is 70 The market for apples in in equilibrium at a price of $.50 per pound. If the government imposes a price  ceiling in the market at a price of $.80 per pound then: A) quantity supplied will increase. B) the price ceiling will not affect the market price or output C) There will be a shortage of the good D) quantity demanded will decrease Answer is B. when ceiling is above equilibrium or floor below equilibrium, there is no effect. Sellers already  charging at equilibrium price.  If the price is above the equilibrium price in the market for grapefruit, total surplus: A) Will increase B) May change, but we cannot determine the change without more information C) Will decrease D) Will not change A lot of people who can’t buy good and a suppliers have a larger inventory that they can’t sell. Answer is C  because suppliers will be sitting on less goods. Inefficient market.  The current price in the market for milk is $2.00. If the government imposed a price floor of $4.00 in this  market total surplus would: A) decrease first, and then increase B) increase C) decrease D) not change The student center on campus has burritos, bagels, or burgers for lunch, and they all cost the same. You  decide to have a burger today, but if they were out of burgers, you would have bought a bagel. Your  opportunity cost is: A) Your enjoyment of the bagel and burrito B) Your enjoyment of the bagel C) Your enjoyment of the burger D) Your enjoyment of the burrito Next best alternative is opportunity cost.  Alex is willing to buy the last ticket to the Billy Bragg concert for $15, while Jake is willing to pay $25. Alex is  first in line and buys a ticket for $15. He then resells his ticket to Jake for $20. By reselling the ticket instead  of going to the concert himself, Alex caused: A) total surplus to increase. B) a deadweight loss of $5 C) Total surplus to decrease D) Consumer surplus to decrease and producer surplus to increase Answer is C. Alex makes money by selling ticket, Jake buys ticket for $5 less than he would have paid.  Say Sarah was choosing between three alternatives: working on her job that pays her $50; writing a term  paper which she values at $40; or going out with a friend, which she values at $20. The opportunity cost of  writing the term paper is: Select one: a. $30 b. $70 c. $20 d. $50  Lena and Jess are roommates. Lena hates to clean the bathroom. Jess will agree to clean the bathroom  only if Lena vacuums the living room. This statement best represents this economic concept: Select one: a. There are gains from trade.  b. The real cost of something is what you must give up to get it. c. "How much" is a decision at the margin. d. People usually exploit opportunities to make themselves better off. Say Sarah was choosing between 3 alternatives: working on her job that pays her $50; writing a term paper  which she values at $60; or going out with a friend, which she values at $80. The opportunity cost of writing  the term paper is: Select one: a. $80  b. $50 c. $130 d. $30 Specialization and trade usually lead to: Select one: a. higher prices. b. lower living standards. c. lower economic growth. d. the exchange of goods and services in markets.  Say you took an average of 5 minutes to answer an ECON problem, and 2 minutes to answer a MATH  problem. If you had a limited time left to study, your best strategy would be to solve: Select one: a. only ECON problems b. It depends  c. only MATH problems Margo spends $10,000 on one year's college tuition. The opportunity cost of spending one year in college  for Margo is: Select one: a. whatever she would have purchased with the $10,000 instead. b. whatever she would have earned had she not been in college. c. $10,000. d. whatever she would have purchased with the $10,000 and whatever she would  have earned had she not been in college.  The local Taco Hut charges the same price for everything on its menu: $3 will buy a taco, a burrito, or  nachos. You buy the taco and think that if you had not purchased the taco, you would have purchased the  burrito. The opportunity cost of the taco is: Select one: a. the $3. b. the $3, your enjoyment of the burrito, and your enjoyment of the nachos. c. the $3 and your enjoyment of the burrito. d. your enjoyment of the burrito.  When the United States and Mexico trade: Select one: a. both Mexico and the United States will be better off.  b. the United States will be worse off because wages in Mexico are so low. c. both Mexico and the United States will be worse off. d. Mexico will be worse off because the United States is a stronger economic  power.
