All else equal, if there are diminishing returns, then which of the following is true if a country increases its capital by one unit?
Output will rise but by less than it did when the previous unit was added.
All else equal, which of the following would tend to cause real GDP per person to rise?
a change from inward-oriented policies to outward-oriented policies, and increase in investment in human capital, strengthening of property rights
If an American-based firm opens and operates a factory in China, then it is engaging in
a foreign direct investment
A recession has traditionally been defined as a period during which
a real GDP declines for two consecutive quarters
outward-oriented policies
allow countries to take advantage of gains from trade, have generally led to high growth for the countries that pursued them, receive widespread support from economists
If companies from foreign countries build and operate factories in China, then China's productivity
and the wages of Chinese workers increase
Expenditures on a nation's domestic production
are equal to its domestic production
In the simple circular-flow diagram, with households and firms, GDP can be computed
as the income received by households, in the form of wages, rent, and profit
GDP per person tells us the income and expenditure of the
average person in the economy
Changes in nominal GDP reflect
both changes in prices and changes in the amounts being produced
An increase in a country's population may contribute to the rate of technological progress because a larger population
brings with it more scientists, inventors, and engineers.
When the consumer price index falls, the typical family
can spend fewer dollars to maintain the same standard of living
a recession is always associated with
declining real GDP
Other things the same, an increase in population growth decreases...
decreases capital per worker. However, there is some evidence that a higher population growth rate may increase the pace of technological progress.
A leading environmental group recently published a report contending that humans are running a "resource deficit" because we are using natural resources faster than they can be regenerated. The group claims that this means that economic growth will eventually stop, and will even be reversed. An economist would
disagree with the report, in part because it ignores the mitigating effects of technological change.
Foreign saving is used for domestic investment when foreigners engage in
either foreign direct investment or foreign portfolio investment
If a good has become more scarce, then we know for sure that
either the demand for it increased or the supply of it decreased.
because every transaction has a buyer and a seller
every transaction contributes equally to an economy's income and to its expenditure
net exports equal
exports minus imports
Other things equal, relatively poor countries tend to grow
faster than relatively rich countries; this is called the catch-up effect.
Gasoline is considered a final good if it is sold by a
gasoline station to a motorist in Los Angeles
Countries with low GDP per person tend to have
higher rates of infant mortality
A country's human capital increases
if its workers become better educated or healthier
inward-oriented policies..
include imposing tariffs and other trade restrictions
if an economy's GDP falls, then it must be the case that the economy's
income and expenditure both fall
human capital is
knowledge and skills that workers have acquired.
An increase in capital will increase real GDP per person more
more in a poor country than a rich country. The increase in real GDP per person will be the same whether the addition to capital is from domestic or foreign investment.
Suppose an economy produces only cranberries and maple syrup. In 2010, 50 units of cranberries are sold at $20 per unit and 100 units of maple syrup are sold at $8 per unit. In 2009, the base year, the price of cranberries was $10 per unit and the price of maple syrup was $15 per unit. For 2010,
nominal GDP is $1800, real GDP is $2000, and the GDP deflator is 90
Suppose an economy produces only burgers and bags of fries. In 2010, 4000 burgers are sold at $3 each and 6000 bags of fries are sold at $1.50 each. In 2008, the base year, burgers sold for $2.50 each and bags of fries sold for $2 each.
nominal GDP is $21,000, real GDP is $22,000, and the GDP deflator is 95.45.
Suppose an economy produces only cheese and fish. In 2010, 20 units of cheese are sold at $5 each and 8 units of fish are sold at $50 each. In 2009, the base year, the price of cheese was $10 per unit and the price of fish was $75 per unit. For 2010,
nominal GDP is $500, real GDP is $800, and the GDP deflator is 62.5.
Babe Ruth, the famous baseball player, earned $80,000 in 1931. Today, the best baseball players can earn more than 400 times as much as Babe Ruth earned in 1931. However, prices have also risen since 1931. We can conclude that
one cannot determine whether baseball stars today enjoy a higher standard of living than Babe Ruth did in 1931 without additional information regarding increases in prices since 1931.
Changes in the GDP deflator reflect
only changes in prices
Changes in real GDP reflect
only changes in the amounts being produced
Country A and country B are the same except country A currently has more capital. Assuming diminishing returns, if both countries increase their capital by 100 units and other factors that determine output are unchanged, then
output in country A increases by less than in country B
The economy's inflation rate is the
percentage change in the price level from the previous period
Country A and country B both increase their capital stock by one unit. Output in country A increases by 10 while output in country B increases by 8. Other things the same, diminishing returns implies that country A is
poorer than Country B. If Country A adds another unit of capital, output will increase by less than 10 units
A country reported a nominal GDP of $85 billion in 2010 and $100 billion in 2009. It also reported a GDP deflator of 100 in 2010 and 105 in 2009. Between 2009 and 2010,
real output and the price level both fell
A country reported nominal GDP of $200 billion in 2010 and $180 billion in 2009. It also reported a GDP deflator of 125 in 2010 and 105 in 2009. Between 2009 and 2010,
real output fell and the price level rose.
accumulating capital requires
requires that society sacrifice consumption goods in the present.
Country A and country B both increase their capital stock by one unit. Output in country A increases by 12 while output in country B increases by 15. Other things the same, diminishing returns implies that country A is
richer than Country B. If Country A adds another unit of capital, output will increase by less than 12 units.
An understanding of the best ways to produce goods and services is called
technology
All else equal, if there are diminishing returns, then if a country raised its capital by 100 units last year and by 100 units this year,
the increase in output was greater last year than this year
a policy that increases savings
will improve economic growth and health outcomes.
if an inexpensive alternative to oil were found, the price of oil adjusted for inflation
would decline as the alternative would reduce the demand for oil.
