GDP

excludes

most

items

that

are

produced

and

sold

illegally

and

most

items

that

are

produced

and

consumed

at

home

because

参考答案:

measuring

them

is

so

difficult.

第一章测试

For

an

economy

as

a

whole,

参考答案:

the

market

value

of

production

must

equal

expenditure.

If

an

economy’s

GDP

falls,

then

it

must

be

the

case

that

the

economy’s

参考答案:

income

and

market

value

of

all

production

both

fall.

According

to

the

circular-flow

diagram

GDP

参考答案:

can

be

computed

as

either

the

revenue

firms

receive

from

the

sales

of

goods

and

services

or

the

payments

they

make

to

factorsof

production.

If

the

price

of

a

dress

is

three

times

the

price

of

a

pair

of

shoes,

then

a

pair

of

shoes

contributes

参考答案:

exactly

one-third

as

much

to

GDP

as

does

a

dress.

A

steel

company

sells

some

steel

to

a

bicycle

company

for

$150.

The

bicycle

company

uses

the

steel

to

produce

a

bicycle,which

it

sells

for

$250.

Taken

together,

these

two

transactions

contribute

参考答案:

$250

to

GDP.

A

dairy

buys

$50,000

worth

of

milk

and

spend

$5,000

on

cartons

and

utilities.

It

sells

the

cartons

of

milk

to

a

grocery

store

for$60,000

that

then

sells

all

of

the

cartons

to

consumers

for

$65,000.

How

much

do

these

actions

add

to

GDP?

参考答案:

$65,000

Sheri,

U.S.

citizen,

works

in

Germany.

The

value

she

adds

to

production

in

Germany

is

included

参考答案:

in

German

GDP,

but

is

not

included

in

Consumption

consists

of

spending

by

households

on

with

the

exception

of

参考答案:

第二章测试

Most,

but

not

all,

athletic

apparel

sold

in

the

United

States

is

imported

from

other

nations.

If

the

price

of

athletic

apparelincreases,

the

GDP

deflator

will

参考答案:

increase

less

than

will

the

consumer

price

index.

Babe

Ruth,

the

famous

baseball

player,

earned

$80,000

in

1931.

Today,

the

best

baseball

players

can

earn

more

than

400times

as

much

as

Babe

Ruth

earned

in

1931.

However,

prices

have

also

risen

since

1931.

We

can

conclude

that

参考答案:

one

cannot

determine

whether

baseball

stars

today

enjoy

a

higher

standard

of

living

than

Babe

Ruth

did

in

1931

withoutadditional

information

regarding

increases

in

prices

since

1931.

The

economy's

inflation

rate

is

the

参考答案:

percentage

change

in

the

price

level

from

the

previous

period.

When

the

quality

of

a

good

deteriorates

while

its

price

remains

the

same,

the

purchasing

power

of

the

dollar

参考答案:

decreases,

so

the

CPI

understates

the

change

in

the

cost

of

living

if

the

quality

change

is

not

accounted

for.

In

1983,

one

could

buy

a

model

radio-controlled

airplane

for

$11.50

each.

Those

same

planes

are

available

today

and

theprice

increased

at

exactly

the

rate

of

inflation.

If

the

CPI

today

is

220.5

and

in

1983

was

105,

what

is

the

price

of

theairplane

today?

参考答案:

$24.15

Which

of

the

following

is

not

correct?

参考答案:

The

purchasing

of

an

interest-earning

deposit

can

increase

or

decrease

over

time,

but

it

cannot<spanstyle='font-family:"TimesNewRoman",serif;font-size:15px

The

real

interest

rate

tells

you

参考答案:

how

fast

the

purchasing

power

of

your

bank

account

rises

over

time.

If

the

nominal

interest

rate

is

5

percent

and

the

rate

of

inflation

is

-2.5

percent,

then

the

real

interest

rate

is

参考答案:

7.5

percent.

Suppose

the

price

of

a

quart

of

milk

rises

from

$1.00

to

$1.20

and

the

price

of

a

T-shirt

rises

from

$8.00

to

$9.60.

If

theCPI

rises

from

150

to

195,

then

people

likely

will

buy

参考答案:

more

milk

and

more

T-shirts.

The

primary

purpose

of

measuring

the

overall

level

of

prices

in

the

economy

is

to

参考答案:

allow

for

the

comparison

of

dollar

figures

from

different

points

in

time.

第三章测试

Last

year

a

country

had

800

workers

who

This

year

the

samecountry

had

1000

workers

who

worked

an

average

8

hours

and

produced

14,000

units.

This

country’s

productivity

was

参考答案:

lower

this

year

than

last

year.

A

possible

source

of

this

change

in

productivity

is

a

change

in

the

Which

of

the

following

is

an

In

a

market

economy,

we

know

that

a

resource

has

become

scarcer

when

参考答案:

its

price

rises

relative

to

other

prices.

Suppose

over

the

last

year

that

the

price

of

iron

ore

increased

from

$1,200

a

ton

to

$1,275

a

ton.

Over

the

level

increased

from

150

to

156.

The

price

of

iron

ore

increased

by

参考答案:

more

than

inflation,

so

it

became

more

scarce.

of

the

best

ways

is

called

参考答案:

technology.

is

参考答案:

proprietary

technological

knowledge.

Which

of

the

following

is

a

determinant

of

productivity?

参考答案:

natural

resources

per

worker

If

the

number

of

workers

in

an

economy

doubled,

all

other

inputs

stayed

the

same,

and

there

were

constant

returns

toscale,

productivity

would

参考答案:

fall,

but

it

would

be

greater

than

one-half

of

its

former

value.
