-A-
Average Total Cost – When total cost is divided by
the level of output, average total cost is defined. For
example, if production of 100 units of output entails a
total cost of $500, average total cost will equal $5 per
unit of output. The average total cost curve is just the
vertical summation of the average variable cost curve and
the average fixed cost curve.
-B-
Balance of Trade – The current account measures the
difference between U.S. imports and exports of goods and
services. That part of the current account balance
reflecting merchandise transactions is known as the balance
of trade. If U.S. imports exceed U.S. exports, a
current-account deficit occurs.
Balanced
Budget – In the case where government expenditures are
exactly equal to tax revenues in a given year, the
government is running a balanced budget for that year.
Barriers
to Entry – A barrier to entry is anything that prevents
firms from entering a market. Many types of barriers to
entry give rise to a monopolistic market structure. Some of
the more common barriers to entry are:
- Patents:
If a firm holds a patent on a production process, it can
legally exclude other firms from using that process for
a number of years. If there are no other production
processes that can be used, the firm that holds the
patent will have a monopoly.
- Large
start-up costs: In some markets, firms will face large
start-up costs – for example, the cost of building a new
production facility. If these start-up costs are large
enough, most firms will be discouraged from entering the
market.
- Limited
access to resources: A monopolistic market structure is
likely to arise when access to resources needed for
production is limited. The market for diamonds, for
example, is dominated by a single firm that owns most of
the world’s diamond mines.
Budget
Deficit – When government expenditures exceed government
tax revenues in a given year, the government is running a
budget deficit for that year. The budget deficit, which is
the difference between government expenditures and tax
revenues, is financed by government borrowing; the
government issues long-term, interest-bearing bonds and uses
the proceeds to finance the deficit. The total stock of
government bonds and interest payments outstanding, from
both the present and the past, is known as the national
debt. Thus, when the government finances a deficit by
borrowing, it is adding to the national debt.
Budget
Surplus – When government expenditures are less than tax
revenues in a given year, the government is running a budget
surplus for that year. The budget surplus is the difference
between tax revenues and government expenditures. The
revenues from the budget surplus are typically used to
reduce any existing national debt. Stock of government bonds
and interest payments outstanding, from both the present and
the past, is known as the national debt. Thus, when the
government finances a deficit by borrowing, it is adding to
the national debt.
Business
Cycle - The tendency of economies to move, over time,
through periods of boom and slump and occurs when real GDP
moves away from its trend path. The business cycle is the
fluctuations in the rate of economic growth that take place
in the economy. These fluctuations appear to occur around
every five years and have probably occurred ever since
economies have occurred! It is the aim of all governments to
try to dampen the effects of the business cycle and get more
balanced long-term growth, but so far they have had limited
success. The peak of the business cycle is usually referred
to as a boom, and the trough as a recession or depression.
-C-
Capital
Resources – Capital Resources are input goods that are
purchased in order to increase the production of future
output. Capital goods include tangible goods, such as
buildings and structures, machinery and equipment, and
inventories of goods in process. Capital goods also include
intangible goods such as franchises, literary rights, and
product brand names. An individual’s investment in knowledge
from taking classes or learning “on the job” is another form
of intangible capital called human capital.
Cartel
– A cartel is defined as a group of firms that gets together
to make output and price decisions. The conditions that give
rise to an oligopolistic market are also conducive to the
formation of a cartel; in particular, cartels tend to arise
in markets where there are few firms and each firm has a
significant share of the market. In the U.S., cartels are
illegal; however, internationally, there are no restrictions
on cartel formation. The organization of petroleum-exporting
countries (OPEC) is perhaps the best-known example of an
international cartel; OPEC members meet regularly to decide
how must oil each member of the cartel will be allowed to
produce. Oligopolistic firms join a cartel to increase their
market power, and members work together to determine jointly
the level of output that each member will produce and/or the
price that each member will charge. By working together, the
cartel members are able to behave like a monopolist. For
example, if each firm in an oligopoly sells an
undifferentiated product like oil, the demand curve that
each firm faces will be horizontal at the market price. If,
however, the oil-producing firms form a cartel like OPEC to
determine their output and price, they will jointly face a
downward-sloping market demand curve, just like a
monopolist.
Complementary goods – If two goods are complements to
each other, the enjoyment that comes with the use of one
good is enhanced by consuming the other along with it. Thus
a decline in the price of a complementary good will lead to
a rise in the demand for its complement. Examples of
complementary goods include bread and butter, and compact
discs and compact-disc player. If the cross-price elasticity
of demand is negative, the goods X and Y must be
complements.
COLA –
Cost-of-living adjustments written into labor contracts
protect workers’ real wages from falling; they raise wages
automatically to keep pace, either partially or totally,
with increases in the price level.
Concentration Ratio – The concentration ratio measures
the market power of the leading firms in an industry. The
concentration ratio is the fraction of total industry sales
composed of the sales of the largest firms in the industry.
The four leading firms in the industry are usually used to
form the concentration the concentration ratio. For example,
the top four firms in an industry might have market shares
of 20, 15, 10, and 8 percent. The concentration ratio based
on the leading four firms equals 53 percent
Consumption possibilities curve - begins at the point
where a company (or state or local govt) specializes in
production of the good in which it has a comparative
advantage and would have a slope equal to the terms of
trade. Since a company (or state or local govt) can trade
for a greater quantity that it can produce, the consumption
possibilities curve has rotated outward and the company (or
state or local govt) has increased it consumption
alternatives.
Contractionary Fiscal Policy – is defined as a decrease
in government expenditures and/or an increase in taxes that
causes the government’s budget deficit to decrease or its
budget surplus to increase.
Cost-Benefit Analysis – Cost-benefit analysis involves
calculation of the present-value dollar costs and benefits
of activities such as building a dam, highway, or
chemical-waste facility. Comparison is then made to
determine whether the potential benefits exceed costs by a
sufficient amount to warrant undertaking the project. This
information is also used for ranking projects. The project
with the greatest benefits compared to costs can be
determined.
Cyclical
Unemployment – The cyclically unemployed are individuals
out of work because the economy is in a state of recession.
Individuals who are cyclically unemployed generally return
to work in the same or a similar position when the recession
is over.
-D-
Demand- quantity of goods or services which buyers
are ready, willing, and able
to take. E.g. Demand for ice cream cones is 6 millions a
day. Consumers' total
demand for a product is reflected in the demand Curve.
Demands factors- a circumstance which influences the
need for a good, service
or factors ot production.
Diminishing returns- given some mixture of factors of
production in which one
of the factors is in less than optimum quantity. Adding
certain percentage of
that factor will increase the output by more than that
percentage until the
optimum is reached. After that point, called the point of
decreasing returns,
adding more of that factor (keeping all other factors
constant) will result in
smaller percentage increases in output. E.g. consider a
factory with large
amount of machinery and natural resources. These can Keep
certain number of
workers occupied. As more labor is added, employees work in
teams. And
efficiency continues to increase up to a certain point.
Further additions over
burden the resources and the output starts decreasing. It
could even find a
negative Change in output results.
-E -
Economic growth- the growth in the total, or per
capita, Output of an economy,
often measured by an increase in real gross national
product, and caused by an
increase in the Supply of factors of production or their
productivity.
The achievement of a high rate of economy growth is one of
the four main
objectives of macroeconomic policy. The significance of
economic growth lies in
its contribution to the general prosperity of the community.
Economics- the examination of the allocation of
limited resources for the
Satisfaction of the unlimited wants Of humans. The problem
is that whereas
wants are virtually without limit, the resources- natural
resources, labor and
capital- available at any one time to produce goods and
services, are limited
in supply; i.e., resources are scarce relative to the
demands They are Called
upon to satisfy. Economics has a microeconomic and a
macroeconomic dimension. Microeconomics is concerned with
the efficient supply of particular products. Macroeconomics
is concerned with the overall efficiency of resource use in
the economy.
Equilibrium market price- the price at which the
quantity demanded of a good is
exactly equal to the quantity Supplied.
-G-
Goods: Anything of value that you would want to buy
or use your scares resources to acquire. A good is anything
that would create a net gain in utility. It is not
necessarily a physical item as in canned goods but if you
wanted your car repaired you might think it is a service but
in the economics world traditional goods and services are
called just “goods”. Example: Crossing the Sahara desert in
a Jeep, you might need to acquire goods along the way. It
might be bottled water or it might be to have your radiator
repaired or it might be direction as to which way to go. One
is a physical thing, one is a service and one is
information, but if you need any of them, the act or
acquiring them would advance your well-being
Normal goods: These are the first choice good of the
consumers. There behavior is true to the law of demand in
that the demand for normal goods increases when income
increases. Normal goods are in contrast to substitute good
or inferior goods. Example:, Diet Coke is to many a normal
good, many people will pay the price because of personal
taste and brand loyalty.
Inferior goods: Goods that are seen as second-rate
substitution goods. They take the place of normal goods if
the demand for the Normal goods shifts to the right and the
price increases. Consumers turn to an inferior good to
replace it. What identifies it as a inferior good rather
than a substitute good is as soon the individual incomes
rises consumers dump the inferior good and return to buying
the normal good.
Substitute Goods: A substitute good is one that is
normally interchangeable in the market like Cola and Root
Beer, the rise in price of one will trigger a rise in demand
for the other. Because people will turn to the substitute
good as prices rise for the normal good, the substitute
becomes more in demand raising its price also. Example:
Increased demand for cola will have an effect on other sodas
but will not affect sales of beer or hot coffee.
Complementary Goods: Goods that tend to be a match
set. The enjoyment of the pair of goods is greater than each
when consumed individually. There for a rise in the demand
for one tends to trigger a rise in the demand for the other,
not as a replacement but as a companion. Example: A
increased demand for pepperoni pizza will cause a
corresponding demand for beer. Same with freedom fries and
ketchup or Corona’s and limes.
Government Spending: Government spending does not
happen in a true market economy. Most venders exist solely
to supply the Government, government regulations and
security need override economic laws of supply and demand.
Also government have a responsibility to spend money goods
that are non-rival and non excludable. Example: National
defense projects, weapon systems and flood control projects
Gross domestic product: It is the value of our market
production and is used as a measure of market activity and
our success in increasing our resources. It si used for
comparison from year to year growth of an individual country
and comparison and is a comparison between countries. GDP is
very controversial because there are so many additional
variables to consider. In its raw form GDP is know as
nominal GDP and the real GDP is the GDP with inflation
factored in. The GDP of the US is 10.57 trillion dollar the
next highest is china with 5.7 trillion .
Horizontal equity: A measure as to whether people of
equal economic means face an equal burden. In taxation
people with the same income conceivably should pay the same
tax rates. An Example of the lack of economic equity would
be the fact that up until recently married couples paid a
higher tax rate that the same two people filing separately.
This horizontal inequality of the tax system was know as the
marriage tax penalty
-I-
Implicit cost The true cost of any transaction is the
explicit cost the monetary cost pulse the implicit cost or
non monetary cost of the transaction. The unseen cost. Most
implicit cost are opportunity cost. The loss of what you
would have done with the money if you had not spent as you
did. Example instead of spending $300 on a rental you drive
the Oldsmobile to San Diego and have to spend $600 dollars
on repair on the 3rd day of a 5 day trip. The total cost is
the $600 (explicit cost) pulse the loss of a days time and
the fact that you cannot afford to go to Sea World (implicit
cost). While you still would have had to fix the car
eventually you know have the added lose of the kids not
seeing Shamu!
Inclusive or industrial unionism: If all workers are
unionized the union can artificially increases the wages of
laborers thereby causing decrees in employment rates. Just
as when the government artificially raises wages, forcing
other out of work, powerful labor unions can do the same.
Import; market activities between different
countries. International transaction cannot proceed with
same freedom as national transaction because of overriding
government concerns for market stability, policy and
national security. Example, you just can’t have weapons
contractors selling armaments to unfriendly countries.
Income effect : In the law of demand The income
effect is the fact that a reduction in price means that you
have more cash left over after buying what you normally
would have, so you take the extra amount and buy more of the
product. Example you go to your favorite sports bar where
you plan to buy $1.50 worth of hot wings at 15 cents each
but you find that the bottom has fallen out of the wing
market and they are being sold for 10 cents each. You buy
your 10 wings and with your 50 cents left you buy 5 more.
This tends to drive the price of wing back up
Inflation The situation where on average, over time,
prices of goods is increasing making the monetary unit worth
less. Inflation occurs because of system wide shortages or a
rise in demand that is not kept up with. Example when the
economy is running good and everybody has cash they tend to
go out and spend it which drives prices up causing
inflation. ( Or when the government needs more money so they
print up a bunch). Either way you monetary unit buys less.
Infrastructure: Major capital outlays that are needed
to get the economy going, no market could function if
someone, the government didn’t take the risk of building or
at least funding the building of a transportation system and
a power grid. Example The Iraqi economy will grow much
faster once the power and civil infrastructure is up and
running
Inelastic : Defines the kind of relationship between
economic factor A and economic factor B A change in one has
vary little if any change in the other. Example: Changes in
cigarette tax rates has an inelastic effect on cigarette
sales
Interest rate; The cost of borrowing money. In
America it is used as a economic throttle, if times are bad,
money is loaned out at a cheep rate in order to stimulate
investments in future activities. If the market is speeding
along and the government fears inflation they will charge
more to borrow money there by putting the brakes on the
economy.
-L-
Labor A type of resource the unit of measure of human
effort put into the economy Labor like other scares
resources are controlled by the same market laws of supply
and demand. Example, as the size of the labor force
increases (surplus) it tends to drive down wages, as
manufacturing increases and competition for workers
increases it tends to drive wages up.
Labor union. Private organization that attempt to
organize workers to act as one in accepting employment and
wage rates or in participating in work stoppages and
strikes. The idea is that you have more negotiating power as
a part of a group that as a single workers. Unions are
effective in maintaining workers rights but tend to
artificially affect wage rates thereby increasing
unemployment.
Law of demand There is a inverse relationship between
the price of an item and what consumers are willing to
purchase. As the price goes up, people will purchase less
and as the price goes down they will purchase more, all
things being equal. (Income, related goods, preferences,
expectations and number of consumers). Example: As the price
of DVD burners has dropped through efficiency of production,
more and more are being sold. when iceberg lettuce hits
$2.00 a head less people buy lettuce.
Law of supply The relationship between the price of a
good and the number of that good that are produced. It is
the maxim quantity of a good that the sellers are willing to
sell at that price at that time. As the price of a good goes
up people seek to make more of them to take advantage of its
increased value, all things being equal. (Number of sellers,
cost of production, expectations, related goods) Example. As
bottled water became popular more and more manufactures
begin producing bottled water
Living standards Measure of the average availability
of resources to individuals in a given country. Computed by
divide the GDP by the population. Like the GDP it has
problems with various factors like inflation and cost of
living but it is a yardstick to measure and compare from
year to year and from country to country China is about
$5,000 The US is about $ 37,800
losses : When the cost of production is more that the
equilibrium price you end up producing losses. Losses show
are the messenger that you are doing something wrong James
D. Gwartney says, “losses are a penalty imposed on those who
misuses resources “
-M-
Marginal revenue - The addition to total revenue
resulting from the sale of one additional unit of output
Minimum
efficient scale - The smallest output of a firm
consistent with minimum average cost (Total cost divided by
output).
Minimum
wage - The lowest compensation you are allowed to pay an
employee for hourly work. It is defined by Federal and state
laws. State laws may be more restrictive than Federal law,
and certainly may differ.
Monetarist
economic views - Followers of Milton Friedman who focus
on the effect of money and monetary policy on changing price
and employment levels.
Monetary multiplier - the amount by which a new deposit into
the banking system (from the outside)is multiplied as it is
loaned out, redeposited, reloaned, etc., by banks
Monetary
rule - That part of the government's economic policy
which tries to control the size of the total stock of money
(and other highly liquid financial assets that are close
substitutes for money) available in the national economy in
order to achieve policy objectives that are often partly
contradictory
Money
supply - There are several formal definitions, but all
include the quantity of currency in circulation plus the
amount of demand deposits. The money supply, together with
the amount of real economic activity in a country, is an
important determinant of its price level and its exchange
rate.
Monopolistic competition - Essentially the same as
imperfect competition: a market situation in which one or
more firms may be capable of influencing the price of the
product. It is characterized by product differentiation,
often established through advertising
Monopsony
model - assumes a market in which employers have some
degree of monopoly buying power. Under monopsony, wages can
in theory be increased within a certain range with no
reduction (and maybe even an increase) in employment. But if
the wage rises above a critical point, then disemployment
kicks in. Thus, a believer in the monopsony model can
consistently favor small increases in the minimum wage while
still opposing large ones. Firms set
Marginal
cost of workers equal to marginal revenue. The wage and
employment level both lower than competitive level where
supply equals demand.
MRP = MRC Rule - The MRP = MRC Rule and Demand for Resources
to maximize profit, a firm will use a resource in an amount
at which the resource’s marginal revenue product equals its
marginal resource cost (MRP =MRC).
-N-
Natural rate monopoly - A market situation in which
economies of scale are such that a single firm of efficient
size is able to supply the entire market demand
near-monies - Assets which are not directly exchangeable for
goods and services but which may be readily converted into
money. A savings account is an example
negative externalities - An externality is an effect of a
purchase or use decision by one set of parties on others who
did not have a choice and whose interests were not taken
into account. Classic example of a negative externality:
pollution, generated by some productive enterprise, and
affecting others who had no choice and were probably not
taken into account.
-O-
Open market - Markets that are free of restrictions
on who can buy and sell
opportunity cost - The best alternative sacrificed to have
or to do something else
output effect - if the price of machinery declines for
example, firms will find it profitable to produce more
output, which in turn increases the demand for labor. If the
substitution effect outweighs the output effect, a change in
the price of a substitute resource will change the demand
for labor in the same direction. If the output effect
outweighs the substitution effect, a change in the price of
a substitute resource will change the demand for labor in
the opposite direction
-P-
Price (a.k.a. Equilibrium) - The price of a product
at which buyers are willing to purchase exactly the
quantities per unit of time that sellers want to sell
Price
ceiling - A maximum price set for a product, usually by
a governmental unit. Sellers of the product are not
permitted to charge higher prices
Price
floor - A minimum price set for a product, usually by a
governmental unit or a group of sellers. Sellers are not
permitted to resell at lower prices.
Price indexes (numbers) - A set of numbers showing
price level changes relative to some base years.
Price discrimination - The sale of the same product
to different persons or groups of persons at different
prices.
Production possibilities (curve) - A graphical
representation of the maximum quantities of two goods and/or
services that an economy can produce when its resources are
used in the most efficient way possible.
Productivity - The average amount of output that can
be produced with a given set of inputs. The productivity of
any resource can be calculated as the ratio of the units of
output to the units of input.
Psychic income - Benefits in the form of personal
satisfaction, rather than monetary gain, that an individual
receives from pursing an endeavor.
Public goods - Goods and services of a collectively
consumed nature, usually provided by governmental units.
Pure market economy - The pure market economy is
based on private ownership and control of resources, known
as private property rights, and on coordination of
resource-use decisions through markets
-R-
Reserve ratio - The ration of reserves to deposits
that banks are required by law to maintain.
Resources - The ingredients that go into the
production of goods and services. They consist of labor
resources and capital resources.
-S-
Shortage - A situation in which buyers of a product
want larger quantities per unit of time than sellers will
place on the market. It may be caused by the existence of an
effective price ceiling.
Social insurance - Government programs, financed
through tax revenues, that guarantee citizens financial
benefits against event which are beyond and individual’s
control, such as old age, disability, and poor health.
Structural unemployment- Relatively long-lasting
unemployment resulting from long-term shifts in economies
and markets rather than short-term savings in economic
conditions. Structural unemployment tends to develop around
major changes in an economy, such as the move from an
industrial to a technological economy. Workers displaced by
the decline of the old economy tend not to be trained in
fields suitable for the new economy, so they remain out of
work.
Substitute good- a good that can be used in place of
another (as the price of one rises the demand for the other
rises)
Substitution effect- When the price of a good
changes, that part of the effect on quantity demanded that
results from the change in the terms of trade between goods;
when the price of an input changes, that part of the effect
on employment that results from the firm’s substitution
toward other inputs
Superior good- A good for which an increase in income
causes an increase in demand, and the income elasticity of
demand is positive and greater than one. A superior good,
also termed a luxury good, is a special type of normal good.
Like a normal good an increase in income causes a rightward
shift in the demand curve. However, a superior good has the
added distinction that the income elasticity of demand is
greater than one. In other words, people don't just buy more
of a superior good, they buy a LOT more
Supply- the amount of a good or service that
producers are willing and able to offer for sale at each
possible price during a period of time, ceteris paribus
Supply factors- determinants other than the price of
the good that influence supply—prices of resources,
technology and productivity, expectations of producers,
number of producers, and the prices of related goods and
services
Supply-side fiscal policy- Supply side economics
holds that increased taxation steadily reduces economic
trade between economic participants within a nation. Taxes
act as a type of trade barrier that causes economic
participants to revert to less efficient means of satisfying
their needs. As such higher taxation leads to lower economic
efficiency. The idea is illustrated by the Laffer Curve.
Surplus-a quantity supplied that is larger than the
quantity demanded at a given price
T-
Tariff- tax on import or export
Tight money policy- A policy in which a central
monetary authority, for example, the Federal Reserve System,
seeks to restrict credit and raise interest rates. A
tight-money policy might be pursued to limit inflation.
Tastes and preferences- a factor of demand
Technology- The sum total of knowledge and
information that society has acquired concerning the use of
resources to produce goods and services. This technology
often takes the form of scientific knowledge (the best
combination of chemicals to make a long-lasting floor wax),
but can also be plain old common sense (irrigate during a
drought, not during a flood). Whether scientific or not,
technology affects the technical efficiency with which
resources are combined in production. An improvement in
technology is thus an increase in the technical efficiency
of production--more output with given inputs or fewer inputs
for a given output. Technology is often embodied in capital
goods. Bigger, better, faster, and less expensive computers
are the result of advances in silicon chip technology.
However, technology is also embodied in labor as human
capital.
-U-
Unemployment- The general condition in which
resources are willing and able to produce goods and services
but are not engaged in productive activities. While
unemployment is most commonly thought of in terms of labor,
any of the other factors of production (capital, land, and
entrepreneurship) can be unemployed as well. The analysis of
unemployment, especially labor unemployment, goes
hand-in-hand with the study of macroeconomics that emerged
from the Great Depression of the 1930s.
Unions- organizations of workers or employees who act
jointly to negotiate with their employers over wages, fringe
benefits, working conditions, and other facets of
employment. The main function of unions is to provide a
balance for the market control exerted over labor by big
business.
-V-
Variable costs- the costs of hiring variable factors
Vertical equity- A system of taxes that treats
unequal people unequally. In other words, if you make the
less income than someone else and pay fewer personal income
taxes, then we have vertical equity.
-W-
Wants- This is often thought of as a psychological
desire which makes life just a little more enjoyable, but
which is not physiological necessary to life. You need
oxygen, but you want a hot fudge sundae. Satisfaction is
achieved by fulfilling wants.
Wealth substitution effect- a change in the real
value of wealth that causes spending to change when the
price level changes
