Suppose the market demand curve for a good is represented by the linear equation Q = 60 - 0.75P. If the market price were to increase from P = $20 to P = $40, then holding all other factors constant:
| the quantity demanded would decrease by 10 units and total expenditures on the good would decrease by $400 |
| the quantity demanded would decrease by 15 units and total expenditures on the good would increase by $300 |
| the quantity demanded would decrease by 30 units and total expenditures on the good would increase by $1200 |
| the quantity demanded would increase by 20 units and total expenditures on the good would decrease by $800 |
| the quantity demanded would increase by 10 units and total expenditures on the good would increase by $100 |
| the quantity demanded would increase by 25 units and total expenditures on the good would increase by $1000 |
A perfectly competitive firms supply curve for a good identifies the:
i. minimum quantity supplied at each price, holding all other factors constant

iii. maximum quantity supplied at each price, holding all other factors constant
iv. firms maximum willingness to accept for each incremental unit of the good (e.g., the first unit, second unit, etc.), holding all other factors constant

Considering the supply side of a market for a good, if a firms supply curve were vertical, then:
| the law of supply holds, and quantity supplied is completely insensitive to changes in price |
| the law of supply holds, and quantity supplied is highly sensitive to changes in price |
| the law of supply fails to hold, and quantity supplied is completely insensitive to changes in price |
| the law of supply fails to hold, and quantity supplied is highly sensitive to changes in price |
| none of the above |
The determinants of supply are:
i. factors other than price that will affect the quantity of a good or service a firm is willing and able to purchase

Suppose a market has two identical sellers. If each sellers supply function is given by P = 20 + Q, then the market supply function is:
| P = 20 + 0.5Q |
| P = 20 + 2Q |
| P = 40 + Q |
| P = 40 + 2Q |
From the market framework discussed in class and the readings, it may be concluded that in order for a good to be exchanged between a seller and a buyer, it must be that:
| buyer maximum willingness-to-pay is greater than seller minimum willingness-to-accept |
| buyer maximum willingness-to-pay is greater than or equal to seller minimum willingness-to-accept |
| buyer minimum willingness-to-pay is greater than or equal to seller maximum willingness-to-accept |
| buyer minimum willingness-to-pay is greater than seller maximum willingness-to-accept |
If the market demand function is given by P = 80 - 0.3Q and the market supply is given by P = 20 + 0.1Q, then the equilibrium price and quantity are:
| P = $35 and Q = 150 |
| P = $65 and Q = 150 |
| P = $26 and Q = 60 |
| P = $28 and Q = 80 |
Of concern are the affects of sustained summer droughts on the domestic supply of wheat. Noting that wheat is a primary ingredient in the production of bread and that potatoes are a substitute for bread, if the supply of wheat declines then it is reasonable to expect:
| the price of wheat to fall, the supply of bread to increase, and the demand for potatoes to increase |
| the price of wheat to fall, the supply of bread to increase, and the demand for potatoes to decrease |
| the price of wheat to rise, the supply of bread to decrease, and the demand for potatoes to decrease |
| the price of wheat to rise, the supply of bread to decrease, and the demand for potatoes to increase |
| the price of wheat to rise, the supply of bread to increase, and the demand for potatoes to increase |
| the price of wheat to rise, the supply of bread to increase, and the demand for potatoes to decrease |
Suppose a perfectly competitive market is initially in equilibrium. If market demand and supply decrease simultaneously, then equilibrium:
| price will rise, but the equilibrium quantity may either rise, fall, or remain unchanged |
| quantity will rise, but the equilibrium price may either rise, fall, or remain unchanged |
| price will fall, but the equilibrium quantity may either rise, fall, or remain unchanged |
| quantity will fall, but the equilibrium price may either rise, fall, or remain unchanged |
Considering the demand side of a market for a good, the consumer surplus derived by an individual:
i. is the difference between the maximum amount the consumer is willing to pay on each unit and the minimum prices that producers are willing to accept
ii. is the difference between the minimum amount the consumer is willing to pay on each unit and the price he/she
actually pays
iii. is the difference between the maximum amount the consumer is willing to pay on each unit and the price he/she actually pays
iv. will decrease if price increases

Suppose the market demand for a good is described by the equation P = 120 - 2Q. If a change in market supply results in price decreasing from P0 = $80 to P1 = $70, then the resulting change in consumer surplus is:
| $225 |
| $400 |
| $575 |
| $625 |
| $750 |
