Econ 4 Midterm
factors that cause demand curve to shift
1. Income 2. Expected future prices 3. Taste/preferences 4. Demographics 5. Price of related goods
When creating a graph for your economics course, which axis is most commonly used to represent price (p)?
Price is most commonly represented on the y-axis.
fiscal policy
economic policies that involve government spending and taxes
In economics, functions often describe cause and effect. In an economic function, the variable being described on the left-hand side represents a(n) ________?
effect
What is a the typical result of a price floor?
excess supply
In a world of scarcity, we will never
meet all of society's wants.
Society gains advantages through trade because of its ability to
specialize resources to the uses where opportunity cost is minimized.
law of supply
the claim that, other things equal, the quantity supplied of a good rises when the price of the good rises
Marginal cost is
the cost of obtaining or producing one more unit of something.
A competitive market is one in which
there is a large number of buyers and sellers.
economic model
a theory or simplified representation that helps explain and predict economic behavior in the real world
When the price of a particular good increases
demand for complementary goods falls.
The assumption of rational behavior:
helps economists explain how people behave in a way that will make choices in their own self-interest
If the total surplus in a market is $500, and there is has no government intervention, but the producer surplus is $200, consumer surplus is ________.
$300
A decrease in the quantity supplied can result from
a decrease in price.
marginal analysis
analysis that involves comparing marginal benefits and marginal costs
Which of the following statements are true if you are comparing a market that is operating at a quantity lower than equilibrium (ie. a price floor) with the same market operating at the equilibrium quantity?
A market operating below equilibrium will transfer some consumer surplus to producers.
Which of the following will shift the supply curve to the left?
An increase in the price of inputs to production.
Identify which of the following microeconomic topics can have an impact on macroeconomic topics?
How do people decide how much to save for the future, or whether they should borrow to spend beyond their current means?
Which of the following statements reflects marginal decision-making?
If we double the order to a dozen cookies, we will pay only 15 percent more.
factorsof production
Land: actual land, but also trees, plants, livestock, wind, sun, water, etc. Economic capital: anything that's manufactured in order to be used in the production of goods and services. Labor: any human service—physical or intellectual. Entrepreneurship: the ability of someone (an entrepreneur) to recognize a profit opportunity, organize the other factors of production, and accept risk.
A local bank sponsors a charity run that raises funds for a non-profit building wells and schools in Mali, Africa. How would the use of the bank's funds for this fundraiser be justified when its goal is to maximize profit?
The money spent is worth the public relations boost it gives to the bank's image.
How does a production possibilities model differ from a budget constraint model?
The production possibilities model demonstrates diminishing returns.
This year the cost of iron used in manufacturing cars has increased by 15%. With the costs for manufacturing cars now up, what effect will this have on the car market?
This will decrease the quantity demanded.
Which is a true statement about marginal benefit?
To an individual, one good may have a larger marginal benefit than than another.
PPF
a model of the economy as a whole, which shows all possible combinations of goods products or services that a society could produce, given the resources it has available. (bowed outwards)
budget constraint
all possible combinations of goods that someone can afford, given the prices of goods and their fixed budget (or time) we have to spend. (straight line)
The theory of rational behavior is
an assumption that economists make to have a useful model for how decisions are made.
According to the law of demand, assuming other factors are held constant,
as the price of bread increases, the quantity of bread demanded will decrease.
Due to limits on our time, money, and effort, we are best off when we allocate things
by constantly assessing the opportunity costs of our choices.
Natural resources, or land, can include the fertility of the land, minerals below it, and what other aspects?
climate
Self-interest is not necessarily selfish, some say. In fact, self-interest likely includes an individual's consideration for
close friends and family.
productive efficiency
given the available inputs and technology, it's impossible to produce more of one good without decreasing the quantity of another good that's produced.
The slope of a budget constraint line is influenced by
how much one item costs compared to the cost of the other item.
negative slope
indicates that two variables are negatively related; when one variable increases, the other decreases, and when one variable decreases, the other increases
factors that affect the supply curve
input prices, technology, natural conditions, government policies.
What is NOT included in economic capital?
money
monetary policy
policy that involves altering the level of interest rates, the availability of credit in the economy, and the extent of borrowing
When certain assumptions are used to create a model of reality, its value can be tested and determined by its ability to
predict outcomes.
If there is a greater quantity supplied than the quantity demanded, in other words, an excess supply of a good or service you are most likely dealing with a
price floor set above the equilibrium price.
If a technology change reduces a company's production costs, it will
shift the supply curve to the right.
________ are generally the result of price ceilings.
shortages
In order to satisfy as many wants as possible, it is necessary to achieve allocative efficiency,
since otherwise output may go to where it is less valued.
When there is an excess supply of goods
suppliers lower prices, which encourages consumers to demand more.
law of demand
the common relationship that a higher price leads to a lower quantity demanded of a certain good or service and a lower price leads to a higher quantity demanded, while all other variables are held constant
Scarcity is imposed on individual households in the form of income and
the prices of the goods that a person may purchase.
In the case of an inverse relationship between two variables, all else remaining constant
the value of the two variables will move in opposite directions from each other.
In general, supply curves slope
upward from left to right
economies of scale
when the average cost of producing each individual unit declines as total output increases
allocative efficiency
when the mix of goods being produced represents the mix that society most desires
