The additional satisfaction from consuming one more unit of a product

Which of the following defines marginal utility?

additional

Which of the following is the best synonym for "marginal" in economics?

Which situation would most likely cause a nation's production possibilities curve to shift inward?

capitalism

market system is known as:

the income elasticity for the good is greater than 0

most goods can be classified as normal goods rather than inferior goods, the definition of a normal good suggests that:

correct

normal profit is an implicit cost

incorrect

over a longer time period after a price-change, the price elasticity of supply tends to decrease

guiding functions of prices in a market system

the "invisible hand" concept refers to the:

scarcity

the basic truth that underlies the study of economics is the fact that we all face:

true

the comment that "taxes must be reduced for the good of the economy" is an example of a normative economic statement.

in the short run, some inputs are fixed and some are variable

the main difference between the short run and the long run is that:

gives private individuals the right to own resources used in production

the market system is an economic system that:

Supply is relatively inelastic so changes in demand have a large effect on price

the price of gold is often volatile because:

the law of demand

the price-elasticity of demand is always negative because of:

opportunity cost

when a state government chooses to build more roads, the resources used are no longer available for public education programs. this dilemma illustrates the concept of:

self-interest in a market system will automatically promote the public interest as well

which of the following best describes the "invisible hand" concept?

A consumer with a fixed income will maximize utility when each good is purchased in amounts such that the:

Increase the supply of ice cream

A fall in the price of milk, used in the production of ice cream, will:

Sets a price floor above the equilibrium price

A government will create a surplus in a market when it:

Inelastic, thus the government's cigarette-tax revenues would rise with a tax increase

A state government wants to increase the taxes on cigarettes to increase tax revenue. 49) Because cigarettes are addictive, we would expect its demand to be:

Inelastic demand for business travel

Airlines charge business travelers more than leisure travelers because there is a more:

A reduction in price results in a decrease in total revenue

Demand is said to be inelastic when:

upward sloping

If A decreases, then B will also decrease. The graph relating the two variables A and B is:

The quantity demanded will exceed the quantity supplied

If a price ceiling is set below the equilibrium price in a market:

Shift the demand curve for product Y to the right

If product Y is an inferior good, a decrease in consumer incomes will:

Cause changes in the quantities demanded and supplied that tend to eliminate the surplus or shortage

In competitive markets, a surplus or shortage will:

Can vary as the result of using a fixed amount of plant and equipment more or less intensively

In the short run, total output in an industry:

price rises and Ed equals 2.47

In which instances will total revenues decline?

The income elasticity for the good is greater than 0

Most goods can be classified as normal goods rather than inferior goods. The definition of a normal good suggests that:

Consume a combination of goods that is beyond (or outside) its production possibilities

Specialization and international trade allows a nation to:

The interdependence of businesses and consumers

The circular flow model illustrates:

a positive number

The cross elasticity of demand between Quaker State motor oil and Texaco motor oil is likely to be:

complementary products

The cross elasticity of demand for product X with respect to the price of product Y is -1.2. It can be inferred that X and Y are:

A consequence of the fact that productive resources are scarce relative to economic wants

The economizing problem faced by a society is:

total utility from all goods consumed

The goal of a rational consumer is to maximize:

Guiding function of prices

The market system communicates changes in market conditions and elicits appropriate responses from businesses and resource suppliers through changes in prices. This is known as the:

Focus on the effect of a single factor on a certain variable

The purpose of the ceteris paribus assumption used in economic analysis is to:

What is produced is ultimately determined by what consumers buy

The term consumer sovereignty means that:

The prices of products are not necessarily measures of the products' usefulness

Understanding the water and diamond paradox is valuable because it explains why:

increase the price of the software

false

a decrease in the price of digital cameras will cause the demand for memory cards to shift to the left

international specialization and trade

a society can consume a combination of goods outside its production possibilities if there is:

the demand for mass transit is price-elastic in the long run

a study of mass-transit systems in american cities revealed that in the long run revenues generally decline after substantial fare increase. this would suggest:

the additional output generated by additional units of an input will diminish

according to the law of diminishing returns:

individuals have to make choices from among alternatives

as a consequence of the problem of scarcity:

purchase more of Y and less of Z

assume that a consumer purchases a combination of products Y and Z and that the MUy/Py=25 and MUz/Pz=20. to maximize utility, without spending more money, the consumer should:

a rightward shift of the production possibilities curve

economic growth may be represented by:

elastic

if a 5% cut in price of a product causes the quantity demanded to rise by 10%, the demand is:

may either be increasing or decreasing, but it must be greater than zero

if total utility is increasing, then marginal utility:

the government makes production and allocation decisions

in a command system:
