Transcript GDP in current dollars

Brief Response
• When you invest, it is best to diversify your
portfolio. Why? (2)
• The most effective portfolio has risky stocks
for fast money growth (but possibly greater
losses) and safer stocks for steady, but slower
money growth.

There are 5 very informative phrases explaining inflation in 2011….. Write on
your “other” paper.
AS THE world economy has recovered, fast-growing emerging economies such
as China and India have struggled to keep a lid on consumer prices,
while stagnating developed countries have faced low inflation rates.
Recently, however, rich-country inflation has also started creeping up:
in December Britain’s consumer-price index hit 3.7%,
while euro-zone inflation also rose above the ECB's target.
Much of the blame has been put on the increase in commodity prices.
But the impact on consumers differs widely between countries.
A larger share of income is spent on food in poorer countries such as China
(33%) and India (46%), so the rise in global food prices is the main driver of
inflation there.
By contrast, pricier energy is a bigger factor in the rich world, although it forms a
relatively small component of consumer spending.
For more detail, see article.

Comparing Food/Energy
Spending Ratios
• Do on your Cornell Notes.
• What two countries spend the most on food?
• Why don’t they spend so much on energy?
• What three countries are about even on food and
energy spending?
• Why do you think that is?
• EC: How will the ratios for India and China
change in the next few decades?

EC: Since 2014, which fact has actually change (it currently does not contribute to
global inflation). Explain how that has affected the world….. (2)
The price of petroleum has dropped significantly,
–
actually making energy cheaper to consumers and producers.
25
Comparing Food/Energy
Spending Ratios
• Do on your Cornell Notes.
• What two countries spend the most on food?
– India and China
• Why don’t they spend so much on energy?
– They are developing economies, few people have cars or use much electricity.
• What three countries are about even on food and energy spending?
– Britain, Germany, The United States
• Why do you think that is?
– They are modern countries, consumers and producers use much technology
that needs energy.
• EC: How will the ratio’s for India and China change in the next few
decades?
– Indians and Chinese consumers and producers will make more money and use
more modern technology that needs energy.
