MARKET
RESEARCH
Market
research
is the
process
of
gathering
and
analyzing
information
to
help
business
firms
and other
organizations
make
marketing
decisions. Business
executives
use
market
research
to
help
them identify
markets
(potential
customers)
for
their
products
and
decide
what
marketing
methods
to use.
Government
officials
use
such
research
to
develop
regulations
regarding
advertising,
other
sales
practices, and product
safety.
Market
research
services
are
provided
by
several
kinds
of companies,
including
advertising
agencies,
management
consultants,
and
specialized
market
research
organizations.
In addition,
many
large business
companies
have
their
own
market
research
department.
Market
researchers
handle
a wide
range
of
tasks.
They
estimate
the
demand
for
new
products
and
services,
describe
the characteristics of probable
customers,
and
measure
potential sales.
They determine
how
prices influence
demand,
and they
test
the
effectiveness
of
current
and
proposed
advertising.
Market
researchers also assess a
company's
sales personnel and
analyze
the
public
"image"
of a
company
and
its
products.
A
market
research
study begins
with
a statement of
the problem
that the
client
wants
to
solve.
This
statement
leads
to
a
detailed
definition
of the
information
to
be
gathered.
There
are two types of
market
research
information,
secondary
data
and primary
data.
Secondary data
are statistics
and other information
that
are
already
available
from
such
sources
as government
agencies
and
universities.
To
save time and
money,
market
researchers use secondary
sources as much
as
they can.
Primary
data are
data
that
must
be
obtained
through
research.
The
chief
techniques
for
gathering
such
data include
mail
questionnaires,
interviews,
retail
store
shelf
audits,
use
of
electronic
scanners
at
retail checkout
counters,
and
direct
observation
in
stores.
The
researchers design and test
research
materials,
such as
questionnaires or guides
for
interviewers.
Finally,
they
collect
the
data, analyze
the
information,
and report the
results
of
their study.
The
computer is
an
important
tool in
analyzing
market
research
data.
Market
research
can
reduce
the
risk
involved
in
many
business decisions, but some
risk always remains. Expenditures
for
market research must
be
carefully
controlled
so
that
the
costs
do
not
exceed
the
probable
benefits
from
reduced
risk.
GROSS DOMESTIC PRODUCT
Gross
domestic
product
(GDP)
is
the value
of all
goods
and
services
produced
in
a country
during
a given
period.
It
is
one
of
the
most
widely
used
measures
of
a nation's
total
economic
performance
in
a single
year.
Measuring
the
GDP. One
way to
determine
the GDP is
to add
up
the
sum
of
spending on four
kinds
of goods
and
services
in
any
year.
(1)
Personal
consumption
expenditures
include
private
spending
on durable goods,
such
as
automobiles
and appliances;
nondurable
goods,
such
as
food
and
clothing;
and
services,
such
as
haircuts
and motion-picture
tickets.
In the United
States,
these expenditures
make
up about
two-thirds
of the GDP each
year.
(2)
Private
investment
expenditures
include
spending
by
business
companies
for
new
buildings,
machinery, and
tools.
They
also
include spending for goods
to be
stored for future
sale.
These expenditures
average
about
20
percent
of the
annual
GDP
of the
United
States.
(3)
Government
purchases
of goods and
services
include
spending
for
new
highways,
missiles,
and
the wages of
teachers,
fire
fighters,
and
government
employees.
Such
spending
amounts
to
about
20
percent
of the
United
States
GDP each
year.
(4) Net exports
represent the value
of domestically
produced
goods
and
services sold
abroad,
less
the value
of
goods and services
purchased from
abroad
during
the
same
period.
Currently,
the
value
of
U.S. exports
is
exceeded
by that
of
U.S. imports.
Net
exports
thus
show a
negative
percentage
in
the
U.S. GDP. The
negative
percentage accounts
for
percentages
in
the
other
three
major
parts
of
the
U.S.
GDP totaling
more
than
100
percent.
Real GDP.
A nation
may
produce
the
same
amount
of goods
and
services
this
year
as it
did last
year.
Yet this
year's
GDP
may
be 5
percent higher
than
last
year's. Such a situation
would
occur if
prices
of goods
and
services
had
risen
by an
average
of
5
percent.
To adjust
for
such
price
changes,
economists
measure
the
GDP in
constant
dollars.
They
determine
what
each
year's
GDP would
be if dollars
were
worth
as
much
during
the current
year
as
in
a certain previous
year,
called
the base
year.
In
other
words,
they
calculate
the
value
of
each
year's
production in
terms
of
the
base
year's
prices.
When
GDP
measured
in
current
dollars
is
divided
by GDP in constant
dollars,
the
result
is
an
index
of
inflation
called
the
GDP deflator.
GDP
figures
do not
tell
everything
about
a nation's
economy.
For
example,
they
tell
little about
the
well-being
of
individuals
and
families.
Even
the
GDP
per capita
does
not tell
who
uses
various
goods
and services.
It
cannot
show,
for
example,
how much
of
the
GDP goes to
the
poorest
20
percent
of
the population
and
how
much
goes
to
the
wealthiest
20
percent.
Nor does
the GDP per capita
tell
anything
about
the
quality
of a country's
goods
and
services.
GDP
excludes
production
by facilities
that
are owned
by
a
nation's
citizens
if the
facilities
are in another
country,
and it
includes
production
by foreign-owned
facilities within
the country.
Some
economists
believe
another
figure,
the
gross
national
product
(GNP), is a better measure
than
GDP. GNP includes all production
by a
nation's
firms
regardless
of
the
firms'
location
and
does
not
include
production
by foreign-owned
facilities
within
the
country.
For
many
years, the
U.S.
Commerce
Department
used GNP to
measure
the country's economic
performance. It switched
to GDP in
1991.
VALUE-ADDED
TAX
Value-added
tax
is
a
tax imposed
by a
government
at
each
stage
in the
production of a
good
or
service.
The
tax
is
paid
by every company
that
handles
a product
during
its
transformation
from
raw materials to
finished
goods.
The amount
of
the tax is determined
by
the
amount
of the
value
that
a company
adds
to
the
materials
and
services
it
buys
from
other
firms.
Suppose that
a company
making
scratch
pads
buys
paper,
cardboard,
and glue worth
$1,000.
The
company
adds
$500
in labor
costs,
profits,
and depreciation,
and
sells
the
scratch
pads
for $1,500. The
value-added
tax is calculated
on the
$500.
The
companies
that
had
sold the paper, cardboard,
and glue
to the
scratch
pads company
would also pay a tax on their
value
added.
In this
way,
the
total
value added
taxed
at
each
stage
of
production
adds
to the
total
value
of the final
product.
Most
firms
that
pay
a value-added
tax try to pass this
expense
on
to
the
next
buyer.
As a
result,
most
of
the
burden
of
this
tax
in
time
falls
on the
consumer.
In
this
sense,
the
final
effect
is
equal
to that
of
a
retail
sales
tax.
The
tax
is
levied
at a
fixed
percentage
rate
and
applies
to
all
goods
and
services.
However,
many
nations use different
rates.
In
these
nations,
the
less
necessary a product
is,
the
higher
the rate
will
be.
In 1954, France became
the first nation to
adopt a value-added
tax.
Today, this
tax is
growing
in popularity,
and
Canada
and
about
40 nations
use it.
It is not used by the
United
States
on the
federal level.
But
most
of
the
other
large
industrial
nations
use it.
Taxation
Taxation is
a
system
of
raising
money
to
finance
government
services
and activities. Governments
at
all
levels--local, state, and national--require
people
and businesses to pay taxes. Governments
use the tax revenue
to pay
the
cost of police
and
fire protection,
health
programs,
schools,
roads,
national
defense,
and
many
other public
services.
Taxes
are as
old
as government.
The
general
level
of
taxes
has
varied
through
the
years,
depending
on the role
of
the
government.
In
modern
times,
many
governments--especially
in advanced industrial
countries--have
rapidly
expanded
their
roles
and
taken
on
new
responsibilities.
As a result, their
need
for
tax
revenue
has
become
great.
Through
the
years, people
have
frequently
protested
against
tax
increases.
In
these
situations,
taxpayers
have
favored
keeping
services
at current
levels
or reducing
them.
Voters
have
defeated
many
proposals
for
tax increases
by state
and
local
governments.
Kinds of
taxes
Governments
levy
many kinds
of taxes.
The
most
important
kinds
include
property
taxes,
income
taxes, and taxes
on transactions.
Property taxes
are
levied
on
the value
of
such
property
as
farms, houses,
stores,
factories,
and
business
equipment.
The
property
tax
first
became
important
in
ancient
times.
Today,
it
ranks
as
the chief source of income for local governments in the United States and Canada. Most states of the United States and provinces of Canada also levy property taxes. Property taxes are called direct taxes because they are levied directly on the people expected to pay them.
Income
taxes
are
levied
on
income
from
such
sources
as
wages
and salaries,
dividends,
interest,
rent, and
earnings
of
corporations.
There
are
two
main
types
of
income
taxes--individual
income
taxes and
corporate income
taxes.
Individual
income
taxes,
also
called
personal
income
taxes,
are applied
to
the
income
of
individuals
and
families.
Corporate
income
taxes
are
levied
on
corporate
earnings.
Income
taxes
may
also
be
levied
on
the earnings of estates
and
trusts.
Income
taxes
generally
are
considered
to
be
direct
taxes.
Most nations in the world levy income taxes. In the United States, income taxes are levied by the federal government, most state governments, and some local governments. Many people and businesses in the United States also pay special income taxes that help fund Social Security programs. These taxes are known as Social Security contributions or payroll taxes. In Canada, income taxes are levied by the federal government and by the country's 10 provincial governments. Taxes on transactions are levied on sales of goods and services and on privileges.
There
are
three
main
types--general sales taxes,
excise
taxes, and tariffs. General sales
taxes
apply
one
rate
to
the
sales of
many
different
items.
Such taxes
include
state
sales taxes
in the
United
States and the
federal sales
tax in
Canada.
The
value-added
tax is a
general
sales tax levied in France,
the
United
Kingdom, and other
European
countries.
It
is
applied
to
the
increase
in value of
a product
at
each
stage in
its
manufacture
and
distribution.
Excise
taxes
are
levied
on
the
sales
of
specific
products
and
on privileges.
They include taxes on
the
sales
of such
items
as
gasoline,
tobacco,
and
alcoholic
beverages.
Other
excise
taxes
are
the
license
tax, the
franchise
tax, and the
severance
tax.
The
license
tax is
levied
on
the
right
to
participate
in
an
activity,
such
as
selling
liquor,
getting
married,
or
going hunting
or
fishing.
The
franchise
tax is
a payment for
the
right
to
carry
on a
certain
kind
of
business,
such
as operating
a
bus
line
or
a
public
utility.
The severance
tax
is
levied
on
the processing
of
natural
resources,
such
as
timber,
natural gas, or
petroleum.
Tariffs are taxes
on imported
goods.
Countries
can
use tariffs
to
protect their
own industries from foreign
competition.
Tariffs
provide
protection
by
raising
the price
of imported goods,
making
the
imported
goods
more
expensive
than
domestic products.
Profit
Profit
is
the amount of
money
a company has
left
over
from
the
sale
of
its products
after
it
has
paid
for
all the
expenses
of
production.
These
expenses
include
costs
of such
things
as raw
materials,
workers'
salaries,
and
machinery.
They also include
a reasonable
return
on
the
owner's
investment,
a salary
for the labor
the owner supplies
to the firm, and other
costs
that
are
hard to
calculate.
A
main
task of
accounting
is
to
define
and
measure
profits
accurately.
Profits
are
vital
to
the
economic
system
of
the
United
States,
Canada,
and
other
countries where
private
enterprise
is encouraged.
In
such
countries,
profits
belong
to the owners
of
companies
or
the
stockholders
of
corporations.
One
of
the
chief
reasons
for
operating
a business
is to
make a
profit.
The
desire for profits
motivates
companies
to
produce
their
goods
efficiently.
This
is because
the lower a
company's
costs are, the greater
its
profits
can be.
A business
can
earn
a
profit
only
by producing goods
and
services
whose
selling
price
is
greater
than
the
cost
of
producing
them.
Therefore,
business
executives
seek
to
use
labor
and
raw materials to
produce
and
sell
things
for
which customers
will
pay
a price that
is greater
than
the cost of production.
Thus,
the
search
for
profits
is
also
the search
for the
uses
of a
country's
labor
and raw
materials that
will
satisfy
consumers
most
completely.
Some
business
executives
constantly
lower
prices
to
capture
sales and
profits
from
their
competitors.
However, there
are
several
reasons
why competition
does
not
eliminate
profits.
For
one thing,
at any
one time, there
will be
many
firms
that
have
discovered
profitable
opportunities
their
competitors
cannot
yet
match.
Sometimes,
new firms cannot duplicate
a profitable product
because
of
patents
or trademarks,
or
for
other
reasons.
Sometimes,
new
firms
cannot
produce
goods
as
cheaply
as established
ones. The
bother
and
risk of
entering
an
unfamiliar
industry
also
keeps
some
new
firms
from
competing
with
a
product
that
is
not
especially
profitable.
The established
firms
can then
enjoy reasonable
profits
without fear
of
new
competition.
BANK
Bank
is a
financial
firm
that accepts people's
deposits
and uses
them
to
make
loans
and investments. People
keep
their
savings
in banks for
several
reasons.
Funds
are
generally
safer in a
bank
than
elsewhere. A bank
checking
account provides
a convenient
way
to
pay
bills. Also, funds
deposited
in
most
bank
accounts
earn
interest
income
for the
depositor. People who
deposit
money
in a bank are actually
lending
it
to
the
bank,
which
typically
pays
interest
for
the
use
of
the
funds.
Banks
help
promote
economic
growth.
Nonfinancial
firms
borrow from banks to buy new equipment
and build
new
factories. People
who
do not have enough
savings to pay immediately
the full price of
a
home,
an
automobile,
or
other
products
also
borrow from banks.
In
these
ways,
banks
help
promote
the production
and
sale
of
goods
and services, and so help
create jobs.
Like all
businesses,
banks
try
to
earn
profits.
They
have traditionally
done
so by accepting
deposits
at
one
rate of
interest
and
then
lending
and
investing
those
funds
at
a higher
rate.
But
large banks
also
earn fees
from
other activities,
such
as
brokerage (buying and selling
securities
for other
investors) or selling
insurance.
Banking
is nearly
as old as civilization.
The
ancient
Romans
developed
a relatively
advanced
banking
system to serve
their
vast trade
network,
which
extended
throughout
Europe,
Asia,
and much
of
Africa.
Modern
banking
began
to
develop
during
the 1200's in
Italy.
The
word
bank
comes
from
the
Italian
word
banco, meaning
bench.
Early
Italian
bankers
conducted
their
business
on
benches in the
street.
Large
banking
firms
were
established
in
Florence,
Rome,
Venice,
and
other
Italian
cities,
and
banking
activities
slowly
spread
throughout
Europe.
By the
1600's,
London
bankers
had developed
many
of the
features
of
modern
banking.
They
paid
interest
to attract deposits
and
loaned
out
a
portion
of
their
deposits
to
earn
interest
themselves.
By
the
same
date,
individuals
and
businesses
in
England
began
to
make
payments
with
written
drafts
on
their
bank
balances,
similar
to
modern
checks.
This article
discusses
banks throughout
the
world.
Because
U.S.
banks
have
unique
features, however,
this
article
also
includes
sections
on
the
regulation
and
the
history
of
banks
in
the
United
States.
Banks in
the United
States
have been
more
strictly
regulated
than
banks
in
many
countries
as a
result
of
the
numerous
bank
failures
that
occurred
in
the
United
States
during
the
Great
Depression
of
the
1930's.
The
United
States
also has more banks
and
banking
assets
than
any other
country
in the
world.
BANK SERVICES
Safeguarding
deposits.
Deposits
in
a
bank
are relatively
safe.
Banks keep
cash
and
other
liquid
assets
available
to meet
withdrawals.
Liquid
assets
include
securities
that
can
be
readily
converted
to cash.
Banks are also
insured
against
losses
from
robberies.
But
the
most
important
safeguard is
the
fact
that
in
most
countries,
governments
have
established
deposit
insurance programs.
The insurance
protects
people from
losing
their
deposits
if
a
bank
fails.
A bank
not
only
keeps
savings
safe
but
also
helps
them grow. Funds
deposited
in
a
savings
account
earn interest
at
a
specified
annual
rate.
Many
banks also offer a special
account
for
which
they issue
a
document
called
a
certificate
of
deposit
(CD).
Most
CD
accounts pay
a higher
rate of interest
than
regular
savings
accounts.
However,
the
money
must
remain
in
the
account
for
a
certain
period,
such
as one
or two
years, to
earn
the
higher
rate of
interest.
Banks
also
offer
money
market
accounts.
These accounts
pay an
interest
rate based
on
the
prevailing
rates
for short-term
corporate
and government securities.
Providing
a
means
of
payment.
People
who
have
funds
in
a
bank
checking
account
can
pay bills by simply
writing a check
and
mailing it. A
check
is
a
safe
method
of
settling
debts,
and
the
canceled
check provides
proof
of
payment.
Customers
may
also ask
a bank
to automatically
pay recurring
bills,
such
as
telephone
and
mortgage
payments,
by a process
called
direct
deposit
deduction.
Many
banks
allow
people
to
pay
bills
electronically
by telephone
or
through
the
Internet
computer
network.
Many banks offer credit
cards.
People
can use the
cards
to
pay for
their
purchases at
stores
and
other
businesses.
The bank then
pays the
businesses directly
and
sends
the customer
a
monthly
bill
for
the amount
charged.
The
cardholder
can
usually
choose
to pay
only part of
the
bill
immediately.
If so, he or
she
must
pay a finance
charge on
the unpaid
balance.
Banks may
also issue
debit
cards,
which
resemble
credit
cards.
When
a cardholder
uses
a
debit
card,
the amount
of
the
purchase
is
deducted
directly
from
the cardholder's
checking
account.
Some
cards
can
be used as
either
credit
or
debit cards.
Making
loans.
Banks
receive funds from
people
who
do
not
need
them
at
the
moment
and
lend
them
to those
who
do.
For
example,
a
couple
may
want to buy a house
but
have only
part of
the
purchase
price saved. If one
or both
of them have a good
job
and
seem
likely to repay a loan,
a
bank
may
lend
them
the additional
money
they
need. To
make
the
loan,
the
bank
uses funds other
people
have
deposited.
A
major
obligation
of
a
bank
is
to
permit
depositors
to
withdraw
their
funds
upon
demand.
But
no bank
has enough
cash readily
available
to
satisfy its depositors
if
all
were
to
demand
their funds
at the same time.
Banks
know from
experience, however, that such
a
demand--called
a run--rarely
occurs.
If
people
are
confident
they
can
withdraw their
funds
at any
time, they will
leave
them
on
deposit
at the
bank
until needed.
As a
result,
banks
can loan
and
invest
a
large
percentage
of
the
funds
deposited
with
them.
In
most
countries,
the
government
limits
the
percentage
of a
bank's
funds
that
can be
used for
loans
and
investment. The
government
simultaneously
sets
a
minimum
percentage
that must
be
kept
on reserve for
meeting
withdrawals.
Trade
Trade
is
buying
and
selling
goods
and
services.
Trade
occurs
because
people
need
and
want things
that
others
produce
or
services
others
perform.
People
must
have
such
necessities
as
food,
clothing,
and
shelter.
They
also
want
many
other
things that
make
life
convenient
and
pleasant.
They
want
such
goods
as
cars,
books, and
television
sets.
They want such
services
as haircuts,
motion
pictures,
and
bus
rides.
As
individuals,
people
cannot
produce
all
the goods
and
services
they
want.
Instead,
they
receive
money for the goods
and services
they
produce
for
others.
They
use the money to buy
the
things
they want
but
do not produce.
Trade
that
takes
place
within
a
single
country
is called domestic
trade.
International
trade
is
the
exchange
of
goods and services
between nations.
It
is
also
called
world
trade or foreign
trade. For detailed
information
on
international
trade.
Trade
has
contributed
greatly
to the
advance
of civilization.
As
merchants
traveled
from
region
to region,
they
helped
spread
civilized
ways
of
life.
These
traders carried the ideas
and inventions
of various
cultures over the
routes
of commerce.
The mixing
of civilized
cultures
was an important
development
in world
history.
The development
of
trade
Early trade.
For
thousands
of
years, families
produced
most
of
the
things
they
needed
themselves.
They grew or hunted
their
own
food,
made
their
own
simple
tools
and
utensils,
built
their
own houses, and
made
their
own
clothes.
Later,
people
learned
that
they
could have
more
and
better
goods and
services
by specializing
and
trading
with
others.
As civilization advanced,
exchanges
became
so
common
that
some
individuals
did
nothing
but conduct trade.
This
class
became
known
as
merchants.
The
most
famous
early
land
merchants
were
the
Babylonians
and,
later,
the Arabs. These
traders
traveled
on foot
or rode donkeys
or camels. The
Phoenicians
were
the
chief
sea
traders
of ancient
times.
Trade
was
very important
during
the
hundreds
of
years
the
Roman
Empire
ruled
much
of
the world.
Roman ships brought
tin
from
Britain,
and
slaves,
cloth,
and gems
from
the
Orient.
For
more
than
500
years
after
the
fall
of
the
Roman
Empire
in
A.D.
476,
little
international
trade
took
place.
The expansion
of
trade
began
in
the 1100's
and 1200's,
largely
because
of
increased
contacts
between
people.
The
crusades
encouraged
European
trade
with
the
Middle East.
Marco
Polo
and
other European
merchants
made
the
long
trip
to the Far
East
to
trade
for
Chinese
goods.
Italians
in Genoa,
Pisa,
and
Venice
built great fleets
of
ships
to
carry
goods
from country
to
country.
A great
period
of
overseas
exploration
began
in
the 1400's.
Trade
routes
between Europe and
Africa,
India,
and
Southeast
Asia were established
as
a
result
of
the
explorations.
In
the
1500's
and 1600's,
private
groups formed
companies,
usually
with
governmental
approval,
to trade
in
new
areas.
Trade
between
Europe
and
America
was
carried
on
by
the
chartered
companies
that
established
the
earliest American
colonies. The colonists
sent
sugar,
molasses,
furs, rice, rum,
potatoes,
tobacco, timber, and
cocoa
to Europe.
In return,
they
received manufactured
articles,
luxuries,
and
slaves.
Trade
also pushed
American
frontiers
westward. Trading
posts sprang
up
in
the
wilderness.
Many
of these
posts later
grew into
cities.
Trade
today affects
the
lives
of
most
people. Improved
transportation
permits
trade
between all
parts of the
world.
Through
specialization,
more
and better
goods
and
services
are
produced.
Increased
production
has
led to higher
incomes,
enabling
people
to buy
more
of these
goods
and
services.
GAME THEORY
Game
theory
is a
method
of studying
decision-making
situations
in
which
the
choices
of
two or
more
individuals
or
groups
influence
one
another.
Game
theorists
refer
to these
situations
as
games
and
to the decision
makers
as
players.
An
example
of such
a
situation
is one in which
the
decision
of each of several countries
about whether to acquire nuclear
weapons is affected
by
the
decisions
of the other
countries.
Game
theory
has
become important
in such
fields
as economics,
international
relations,
moral
philosophy,
political
science,
social
psychology, and
sociology.
Its
roots
are generally
traced
back
to
the book
The
Theory of
Games
and
Economic
Behavior
(1944), by Hungarian-born
mathematician
John
von
Neumann
and
Austrian
economist
Oskar
Morgenstern.
Game
theorists
have
identified
many
types
of
games.
In
zero-sum
games, the
players
have
opposite
interests. In nonzero-sum games,
also
called mixed-motive
games,
they have some
interests in common.
When
the
players
can
agree
on
a plan
of action, they are in a
cooperative
game.
In a non-cooperative
game,
the players
cannot
coordinate
their
choices.
Coordination
may
be
impossible
if the players
cannot
communicate,
if no institution
exists to
enforce
an agreement,
or if
coordination is forbidden
by
law,
as
in
the
case
of
antitrust
laws.
Game
theory's
most
famous
game
is
called
Prisoner's Dilemma,
a
non-cooperative
game
that
involves
the
following
imaginary
situation: The
police
arrest
two
suspects
and
keep
them
isolated from
each other.
Each
prisoner
is
told
that
if
only
one
of them confesses,
the
one
who
confesses
will
go free but
the
one who remains silent
will
receive
a
severe
sentence.
They
are
also
told
that
if
they
both
confess,
each will
receive
a moderate
sentence,
and
if
neither
confesses,
each
will
receive
an
even
milder
sentence. Under
these conditions,
each
prisoner
is
better off confessing
no matter
what
the
other
one
does.
Yet
by pursuing
their
own
advantage
and
confessing,
both
get
harsher
sentences
than
they
would
have received
if they
had
trusted
each
other
and
kept
quiet.
Prisoner's
Dilemma
highlights
and
summarizes
a
conflict
between
individual
and
group
interests
that
lies
at
the heart
of
many
important
real-life
situations. For example,
when farmers maximize
their
production,
prices
fall
and
all
the
farmers
suffer.
Collectively,
the farmers
would
be
better off restricting
the
amount
they plant.
Nonetheless,
it is to each farmer's
individual
advantage
to plant as
much
as
possible.
Decisions
about
paying
taxes,
protecting
the environment,
or
acquiring
nuclear
weapons
may
also
reflect
this
tension
between
what
is
good
for
the
decision
maker
and what
is
good
for the group.
DEFLATION
Deflation
is
a
decline
in
the general level
of
prices
in
an
economy.
It
is
the opposite
of inflation,
in
which prices rise. Deflation
is
rarer
than
inflation,
but
its
consequences
can
be
more
severe.
Each
year, about
5 percent of
all
countries
experience
deflation.
Most of
them
are less developed nations,
and
the
deflation
they
experience
is
brief.
However,
many
industrialized
countries,
including
the
United
States,
the
United
Kingdom, Japan,
Australia,
and
Canada,
have
experienced
periods of
deflation.
Deflation
sometimes
occurs
when an economy
undergoes
a
depression
or a
recession.
During
depressions
and
recessions,
the total
output
of
an economy
declines. Depressions
are
more
severe
than
recessions.
The United States experienced
sharp
deflation
during the Great Depression of
the
1930's.
Deflation can be caused by competition among producers of goods and services to increase sales by reducing their prices. But weak demand for goods and services is the chief cause of almost all periods of deflation. In the United States during the Great Depression, several forces acted simultaneously to reduce demand. Banks had little money to lend to qualified individuals and businesses. The Federal Reserve System, the nation's central bank, failed to stimulate the economy by increasing the amount of money in circulation. Also, the federal government sought a balanced budget, which prevented it from cutting taxes or increasing its own spending. All of these factors contributed to a decline in demand and thus to deflation.
