Question;Name;True/False;30%;Indicate;whether the statement is true or false.;1. Total utility can be objectively measured in;numbers that indicate usefulness or benefit to the consumer.;2. As a rule, the more of a commodity a consumer;acquires, the smaller will be her total utility from that good.;3. An optimal purchase is one that maximizes;total utility.;4. If the marginal net utility of beer is a;positive number, the consumer should buy more beer in order to maximize;utility.;5. Consumer surplus is the difference between;the worth of a commodity to the consumer and the price the consumer pays for;the commodity.;6. The resolution of Adam Smith's diamond-water;puzzle is based on the distinction between marginal and total utility.;7. Scarcity raises both price and marginal;utility but generally reduces total utility.;8. Quantity demanded is not only affected by;price but by variables such as income and the prices of other goods.;9. The market demand curve is the horizontal;summation of all individual demand curves.;10. A change in the price of one good results in;a rotation of the budget line, so that it is steeper or flatter.;11. A decrease in the price of one good results;in a parallel shift in the budget line.;12. The budget line and the indifference curve;are geometric devices used to provide a closer look at consumer choice.;13. An increase in income shifts indifference;curves outward.;14. A consumer will consume the combination of;goods at the point of tangency between the budget line and the indifference;curve.;15. A consumer will consume the combination of;goods at the crossing point of a budget line and indifference curve.;16. A vertical demand curve has an elasticity of;demand equal to zero.;17. A horizontal demand curve is perfectly;elastic because a change in price will not induce a change in quantity;demanded.;18. A horizontal demand curve is perfectly elastic;because a change in price will induce an infinite change in quantity demanded.;19. A straight-line demand schedule has the same;elasticity throughout its length.;20. The unit-elastic demand curve is a;rectangular hyperbola.;21. If price goes up 20 percent and quantity;demanded declines by 10 percent, total revenue will rise.;22. If a demand curve is unit elastic, then P;times Q will remain constant when P changes.;23. A demand curve with unit elasticity can never;touch either the vertical or horizontal axes.;24. A price increase will always cause a firm's;revenue to fall, because they will sell less of the good.;25. Necessities such as food and shelter have;inelastic demand.;26. If there are many close substitutes available;for a good, its elasticity of demand will be higher.;27. Since an individual spends a small share of;her income on salt, the elasticity of demand is likely to be low.;28. Cross-elasticity of demand could be used to;measure the responsiveness of the quantity demanded of swimming pools to a;change in the price of picnic tables.;29. Demand curves often do not remain stationary;they shift because of changes in other variables.;30. A decrease in the price of a good will cause;a movement along the demand schedule to a higher quantity demanded.;Multiple;Choice 30%;Identify the;choice that best completes the statement or answers the question.;31. Lana spent $5 to see a movie. We know;a.;the movie was worth 500;utils.;b.;Lana's total utility;from movies was $5.;c.;the movie was worth;at least $5 worth of other goods.;d.;the movie increased;marginal utility.;32.

Suppose that Joan, the only consumer of pork;has a downward-sloping demand curve for pork and faces an upward-sloping supply;curve.
