Which statement is the best definition of the price elasticity of demand? a)The ratio of the percent change in demand to the percent change in income. b) The ratio of the percent change in price to the percent change in quantity demanded. c) The absolute value of the slope of the demand curve. d) The ratio of the percent change in quantity demanded to the percent change in price.
a) They slope upward because higher prices lead individual businesses to supply a larger quantity and more businesses are willing to supply goods and services.
Why are supply curves typically upward-sloping? a) They slope upward because higher prices lead individual businesses to supply a larger quantity and more businesses are willing to supply goods and services. b) They slope upward because sellers demand more when prices are lower. c) They slope upward because sellers prefer to sell more when prices are lower. d) They slope upward due to the law of demand.
c) go; greater
You are considering whether you should go out to dinner at a restaurant with your friend. The meal is expected to cost you $50, you typically leave a 20% tip, and a round-trip Uber ride will cost you $15. You value the restaurant meal at $30 and the time spent with your friend at $50. You should ____ to dinner with your friend because the benefit of doing so is _____ than the cost. a) go; less b) not go; less c) go; greater d) not go; greater
a) shampoo
You are given data on four products — toothpaste, shampoo, soap, and laundry detergent. The absolute value of the price elasticity of demand for toothpaste is 4. The absolute value of the price elasticity of demand for shampoo is 0.2. The absolute value of the price elasticity of demand for soap is 0.5. The absolute value of the price elasticity of demand for laundry detergent is 2. Which product has the most inelastic demand? a) shampoo b) toothpaste c) laundry detergent d) soap
a) The supply of cacao beans, used to produce chocolate, has fallen around the world.
You eat M&Ms every day. When you go to the store to buy some, you find that M&Ms are more expensive than they were last month. Which of the following could explain why M&Ms are more expensive? a) The supply of cacao beans, used to produce chocolate, has fallen around the world. b) A new study finds that the benefits of eating chocolate are not as great as previously thought. c) A new robot has been installed at the Mars chocolate company that reduces the time needed to produce M&Ms by half. d) Consumers are now purchasing fewer M&Ms compared to other types of chocolates.
substitutes, large
You may have observed that items such as different brands of aspirin, tomato sauce, or gasoline are typically priced the same as each other. This is particularly true when consumers can find these goods in close proximity to each other. For example, prices are often the same at gas stations that are on opposite sides of the street. Prices are also generally the same for products next to each other on the same grocery store shelf. The aforementioned examples are goods that are likely to be ______. You would expect the value of the cross-price elasticity to be ______, because the opportunity cost of getting information on price is low.
interdependence principle
Your best choice depends on your other choices, the choices others make, developments in other markets, and expectations about the future. When any of these factors changes, your best choice might change.
indifference curve
a curve on a graph (the axes of which represent quantities of two commodities) linking those combinations of quantities which the consumer regards as of equal value.
utility
as indifference curves move outwards they provide more what?
resource availability and time constraints
ability to store products as inventory, availability of inputs, capacity to expand production, the ability of suppliers to enter and exit the market, time to adjust to production going up or down
accounting cost
actual expenses plus depreciation charges for capital equipment
determinants of price elasticity of demand reflecting on opportunity costs
availability of completing products, specific product vs broad categories, ability to search for alternates, time to adjust consumption decisions, necessities, share of consumer income
marginal decision making
comparison of additional benefits of a choice against the additional costs it would bring, without considering related benefits and costs of past choices
producer theory
characterizes producers' or sellers' choices in a systematic way
mostly decreasing
output is increasing at what rate?
fixed cost equation
total cost - variable cost
profit
total revenue minus total cost
resources and technology changes
what can change the PPF?
inelastic supply
what do rare inputs have?
make it more elastic
what do these do to elasticity of demand?: more substitution possibilities , more time to adjust consumption decisions, not a necessity , larger share of consumer income
make it more inelastic
what do these do to the elasticity of demand?: fewer substitution possibilities, less time to adjust consumption decisions, is a necessity, smaller share of consumer income
money and the stock market
what is scarcity not about?
lower prices and increase market quantity
what is the goal of a subsidy?
the law of diminishing marginal product
what is the short-run technology constraint between inputs and outputs?
