According to the graph, after the tax was levied, consumer surplus, producer surplus, tax revenue and dead weight loss are represented by areas a. Consumer surplus = A; Producer surplus = F; Tax revenue = B+D; Deadweight loss = C+E b. Consumer surplus = A+B+C; Producer surplus = D+E+F; Tax revenue = B+D; Deadweight loss = C+E c. Consumer surplus = A; Producer surplus = F; Tax revenue = C+E; Deadweight loss = B+D d. Consumer surplus = F; Producer surplus = A; Tax revenue = B+C; Deadweight loss = D+E
a. Consumer surplus = A; Producer surplus = F; Tax revenue = B+D; Deadweight loss = C+E After the tax is applied, the price paid by consumers rises to P3 and quantity falls to Q2. This means that consumer surplus is impacted through the loss of areas B and C, leaving only A as the area above the price and below the demand curve. Producer surplus is similarly affected: while the consumer pays price P3, only price P2 is kept by the producer. Above the supply curve and below price P2 is area F. The tax - as indicated by the diagram - is the difference between the price paid by the consumer and the price received by the producer. Multiply this tax times the quantity sold (Q2) to find total area of the tax, which is reflected in areas B and D. Finally, the loss of gains from trade is the remaining areas C and E which represent deadweight loss.
Each of the following would definitely decrease the equilibrium price with the single exception of: a. Increased cost of raw materials and increased popularity of the product b. Lowered cost of raw materials and increased popularity of the product c. Increase in the number of producers and increased numbers of consumers d. Increase in the number of producers and an increase in the price of a substitute good e. An increase in a government subsidy placed on a good and an decrease in popularity of the good in question

In the graph below, if S1 represents supply before the imposition of an excise tax and S2 represents supply after the tax is imposed, the burden (or incidence) of the $30 tax in the graph would be borne as follows a. Producer pays all $30 of tax b. Consumers pays all $30 of tax c. Each pays $15 of tax d. Consumer pays $10, Producer pays $20 e. Consumer pays $20, Producer pays $10
d. Consumer pays $10, Producer pays $20 As demand is more elastic than supply, producers will pay more. It appears from this diagram that at the new equilibrium quantity, producers would receive approximately $40 while the consumers will pay $70. Previously the producer received $60 for the good, so they pay $20.
According to the graph, before the tax was levied, consumer and producer surplus are represented by areas a. Consumer surplus = A; Producer surplus = F b. Consumer surplus = D+E+F; Producer surplus = A+B+C c. Consumer surplus = F; Producer surplus = A d. Consumer surplus = A+B+C; Producer surplus = D+E+F
d. Consumer surplus = A+B+C; Producer surplus = D+E+F Consumer Surplus is the area below the demand curve and above price. This encompasses areas A, B and C (from the demand curve down to P1 and out to Q1. Producer Surplus is the area above the supply curve out to Q1 and below the price P1. In this diagram D, E and F are the area of producer surplus.
Which of the graphs in Figure 1 indicate that a firm can sell any or all of its output at the prevailing market price? a. A b. B c. C d. D e. It is impossible to determine the correct answer to the question from the information given.
d. D Regardless of price, if supply is perfectly elastic they can offer as much as possible.
If production cost increases and income decreases (the good is normal), we can correctly conclude that I. Equilibrium price will decrease II. Equilibrium price is indeterminate III. Equilibrium quantity will fall IV. Equilibrium quantity is indeterminate a. I only b. I and III only c. II and IV only d. II and III only e. I and IV only
d. II and III only A decrease in supply raises price and lowers quantity. A decrease in demand lowers price and quantity. Both decrease quantity, but price may rise or fall depending on which shift is larger.
If a decrease in the price of one good increases the demand for another good, then these two goods are a. regular goods b. substitute goods c. public goods d. complementary goods e. independent goods
d. complementary goods When the price of peanut butter falls, I buy more peanut butter. Ceteris paribus, this increases the demand for jam, bread, celery, coconut curry sauce, and other things that are delicious with peanut butter.
Which of the following is true about the distances between average variable cost and average total cost when graphed? a. As output increases the difference between them gets smaller b. As output increases the difference between them gets larger c. Is equal to average fixed cost at all levels of output d. Is zero at all levels of output e. A and C are both correct
e. A and C are both correct This is by definition. Fixed costs + variable costs = total costs, so the difference between ATC and AVC is always AFC. Additionally, as output increases, the quantity of AFC decreases, so the two curves get closer.
The graph below depicts the milk market. The horizontal line, P, represents a price ceiling imposed by the government. Which of the following is true? a. At equilibrium, the quantity demanded is 800 gallons. b. At the price ceiling, there is a surplus. c. The quantity demanded at the price ceiling will equal the quantity supplied. d. The equilibrium price would be $1 without the price ceiling. e. The quantity supplied at the price ceiling will be the quantity actually sold.
e. The quantity supplied at the price ceiling will be the quantity actually sold. None of the other response are accurate in this graph. The quantity supplied at equilibrium is defined by the price ceiling, which appears to be 500 in this problem.
