ECONOMICS EXAM
what is utility?
"The satisfaction one receives from a good"
Consider 2 points on the PPF: point A, at which there are 10 apples and 20 pears, and point B, at which there are 7 apples and 21 pears. If the economy is currently at point A, the opportunity cost of moving to point B is
3 apples; Slope= 10-7/20-21= 3/-1= -3
supply curve
A curve that shows the direct or positive relationship between price and quantity supplied.
If increasingly more units of good Y must be given up as each successive unit of good X is produced, then the PPF for these two goods is a
A downward-sloping curve that is bowed outward (increasingly means opportunity cost is not constant).
demand curve
A line that represents the inverse relationship between quantity demanded and price.
suppose the economy goes from a point on its production possibilities frontier (PPF) to a point below that PPF. Assuming that the PPF has not shifted, this would be due to
An increase in unemployment of some resources. (a loss of resources shifts the PPF inwards and unemployment moves point away from PPF)
Which of the following is an illustration of the law of increasing opportunity costs?
As more cars are produced, the opportunity cost of each additional car is greater than for the preceding unit.
Law of demand
As the price of a good goes up (down), the quantity demanded goes down (up).
Law of supply
As the price of a good rises (falls), the quantity supplied rises (falls), ceteris paribus
Which of the following pairs of goods would be most likely to be complements?
DVD's and DVD players
Good X is a normal good. If the average income of those who buy good X rises, the __________ curve for good X will shift __________ resulting in a(n) __________ in the equilibrium price of X and a(n) ___________
Demand; rightward; increase; increase
which of the following statements is true?
If scarcity did not exist, neither would a PPF (without scarcity, we can produce infinite quantities, there is no frontier).
Increasing (Slope increases as we move from y to x)
In a bowed-outward/concave PPF we assume the opportunity cost is
Constant (slope of a straight line is constant)
In a straight line PPF, we assume the opportunity cost is
these statements are true
In a world of efficiently used resources, More of one good necessarily means less of some other good // Efficiency implies that it is impossible to get more of one good without getting less of another.
PPF is bowed outward as a result of
Increasing opportunity costs
Productive efficiency implies that
It is impossible to obtain gains in one area without losses in another. (Moving from point A to point B can only be achieved by giving up pizzas to make cell phones) there is no waste of resources.
What does the slope of the PPF represents of producing one good?
Opportunity cost (The slope tells you how much of one good we must give up to produce another).
Through war, many of the factories in country 1 are destroyed and many of its people are killed. As a result, the country's
PPF after war has probably shifted to the left (inwards) compared to its PPF prior to the war
Unattainable
Points outside (or beyond) the PPF are
PPF/ Production Possibilities Frontier
Represents the possible combinations of two goods that can be produced when all resources are used efficiently
A decrease in the quantity of resources
Shifts the PPF leftward (inward)
An increase in the quantity of resources
Shifts the PPF rightward (PPFs expand with more resources and/or better technology).
There is a technological improvement in the production of good X. As a result, the ____________ curve for good X will shift _____________ resulting in a(n) _____________ in the equilibrium price of X and a(n) _____________
Supply; rightward; decrease; increase
Which of the following is a normative macroeconomics statement?
The central bank should increase the nation's money supply. (what should be)
Resource X (ex: lumber) is necessary to the production of good Y (ex: door frames). If the price of resource X rises,
The supply curve of Y shifts leftward (falls)
Which of the following will not shift a supply curve?
a change in the good's own price.
inflation
a general increase in the prices of goods and services, or an increase in the price level (CPI)
price index
a measure of the price level
An advance in technology causes
a rightward shift in the supply curve
At a price below the equilibrium price, there is
a shortage
At a price above the equilibrium price, there is
a surplus
price level
a weighted average of the prices of all goods in the economy
A vertical supply curve represents:
an independent relationship between price and quantity supplied.
If Max's demand for hot dogs falls as his income rises, then for Max hot dogs are
an inferior good - income rises (falls), demand falls (rises).
The civilian non-institutional population consists of everyone in the population who is
at least 16 years of age, not in the armed forces, and not institutionalized.
Points inside (or below) the PPF are
attainable but productive inefficient
why do we study economics?
because we have unlimited wants and limited resources. (to satisfy the wants, we need goods and services).
Produced goods used as inputs for the production of other goods comprise the resource known as
capital.
as the price of paper rises, the demand for pence falls. Therefore, paper and pencils are
complements - Quantity demanded of X falls (rises) as price of Y rises (falls)
When economists speak of scarcity, they are referring to the
condition in which people's wants outstrip the limited resources available to satisfy those wants
Both country 1 and country 2 are located on their respective production possibilities frontiers (PPF) but country 1 produces twice the output that country 2 produces. It follows that
country 1's PPF lies further to the right than country 2's PPF
The cyclical unemployment rate is defined as the
difference between the actual unemployment rate and the natural unemployment rate
The law of supply states that price and quantity supplied are
directly related, ceteris paribus(all other things equal)
Resource X is necessary to the production of good Y. If the price of resource X falls, the equilibrium price of Y will __________ and the equilibrium quantity of Y will __________
fall; rise
The law of diminishing marginal utility helps to explain that
for a given period of time, the marginal satisfaction of consuming additional units of a good decreases with each additional unit.
Unemployment that arises as a result of the time it takes for unemployed people to locate a job utilizing their transferable skills is called
frictional unemployment
The law of demand states that price and quantity demanded are
inversely related, ceteris paribus(all other things equal).
Marginal benefit
is the benefit of consuming/producing one more unit
A market is said to be in disequilibrium if?
it exhibits either a surplus or a shortage
Nominal income
it is income nor adjusted for inflation
real income
it is nominal income adjusted for inflation
productive inefficiency implies that
it is possible to obtain gains in one area without losses in another. (points inside PPF are inefficient- there's waste of resources. when moving from point A to point B, we produce more phones without giving up pizzas).
what are the four broad categories of resources?
labor, land, capital, and entrepreneurship.
The physical and mental talents people bring to production processes comprise the resource called
labor.
Minerals, animals, water and forests are all considered to be the resource known as
land
Efficiency exists when
marginal benefits equal marginal costs
Costs connected to consuming an additional unit of a good are called
marginal costs.
An economy is productive efficient if it produces
maximum output with given resources and technology.
A price ceiling is a government-mandated
maximum price above which legal trades cannot be made
A price floor is a government-mandated
minimum price below which legal trades cannot be made
Opportunity cost is the __________ alternative forfeited when a choice is made.
most highly-valued
Unemployment caused by frictional and structural factors in the economy
natural unemployment
If the cyclical unemployment rate is negative, then the
natural unemployment rate is greater than the actual unemployment rate in the economy.
In order to be classified as unemployed, a person must

Job loser
person who was employed in the labor civilian labor force and was either fired or laid off
Reentrant
person who was previously employed, hasn't worked for some time, and is currently reentering the labor force
The civilian non-institutional population can be broken down into two groups:
persons not in the labor force and persons in the labor force.
Oil producers expect that oil prices next year will be lower than oil prices this year. As a result, oil producers are most likely to
place more oil on the market this year, thus shifting the present supply curve of oil rightward
Attempts to determine "what is" are part of __________ economics.
positive economics
The minimum wage is an example of a
price floor
A "decrease in the quantity demanded" means that
price has increased and consumers therefore want to purchase less of the good. Demand curve does not shift.
A price ceiling set below the equilibrium price will
result in a shortage of the good.
A price floor set above the equilibrium price will
result in a surplus of the good.
An increase in the number of buyers in a particular market will result in a
rightward shift in the demand curve

rise; fall; more
The condition in an economy that makes a "rationing device" a necessity is the fact that
scarcity exists
Economic growth causes the PPF to
shift rightward
If people begin to favor science fiction novels to a greater degree than previously, the demand curve for science fiction novels
shifts rightward
The unemployment due to changes in the types of skills employers require is called
structural unemployment
As the price of good A rises, the demand for good B rises. Therefore, goods A and B are
substitutes - Prise of X rises, Quantity demanded of X rises; Price of X falls, Quantity demanded of X rises.
An economist says, "technological advances have the power to lower the prices of many of the goods we buy." Here is how this works:
technological advances lead to greater supply, which leads to lower prices.
Marginal cost
the cost of producing one more unit
A "decrease in demand" means that
the demand curve has shifted to the left.
The opportunity cost of attending college is
the highest valued alternative one forfeits to attend college.
The higher the opportunity cost of attending college,
the less likely an individual will go to college
"Full employment" is said to exist when the unemployment rate equals
the natural unemployment rate.
economics is defined as

the study of how prices are determined in the computer industry
In the context of economics, Entrepreneurship is
the talent for organizing the use of land, labor and capital.
Tobacco production is one of the more heavily subsidized industries in the United States. Suppose that as a result of intense lobbying from health-related concerns, congress repeals the tobacco firms' subsidies. Which of the following scenarios would likely occur?
the tobacco firms' supply curve would shift leftward, since it would now cost more to produce each level of output.
A person in the civilian labor force falls into one of two categories:
unemployed or employed.
