Last year, real GDP in an imaginary economy was $125 billion and the population was 5 million. This year, real GDP is $132 billion and the population was 5.2 million. What was the growth rate of real GDP per person during the year?
1.54% (125/5=25,000 132/5.2=25,384. So, 25,384(this year)-25,000(previous year)/25,000(previous year) *100= 1.536=1.54)

Which of the following is an example of foreign portfolio investment? a) In the 1800s, Europeans purchased stock in American companies that used the funds to build railroads and factories. b) Ford Motor Company builds a car factory in Mexico. c) A European firm opens an interior design firm in San Francisco, CA. d) A European firm opens a new toy factory in China.
a) In the 1800s, Europeans purchased stock in American companies that used the funds to build railroads and factories. Feedback: Correct. A capital investment that is owned and operated by a foreign entity is called foreign direct investment, whereas an investment that is financed with foreign money but operated by domestic residents is called foreign portfolio investment. Therefore, the Europeans who purchased stock in American railroads companies engaged in foreign portfolio investment.

true
Consider the case of Crusoe's economy. Suppose Robinson Crusoe spends two hours to find ten turtle eggs. What is his productivity?
5 turtle eggs per hour. Feedback: Correct. A correct way to measure productivity is to divide the quantity of output by the number of hours worked: 10 turtle eggs / 2 hours = 5 turtle eggs per hour.
the property whereby countries that start off poor tend to grow more rapidly than countries that start off rich

False
Other things the same, when an economy increases its saving rate, consumption increases now and production rises later. True False
False
Suppose an economy experiences an increase in its saving rate. The higher saving rate leads to a higher growth rate of productivity in the long-run. True False
False
The historic data show that the world's poorest countries are doomed to remain in poverty. True False
False (same goes for rich staying rich, neither is set to stay that way)
Knowledge and skills that workers acquire through education, training, and experience
Human Capital
Inputs into the production of goods and services that are provided by nature, such as land, rivers, and mineral deposits
Natural Resources
Last year, a chocolate factory made 60,000 bars employing 100 workers, each of whom worked 8 hours per day. This year, the factory produced 70,000 toys, employing 80 workers, each of whom worked 10 hours per day. What can you say about factory's productivity?
Productivity increased by 16.7%. Feedback: Correct. Last year, productivity was 60,000 toys/ 100 workers/ 8 hours = 75 bars per hour. This year, it was to 70,000 toys / 80 workers/ 10 hours = 87.5 toys per hour. The productivity grew by 100* ((87.5 bars per hour - 75 bars per hour)/ 75 bars per hour) = 16.7%.
An economy which consumes only what it produces has the standard of living that is tied to productivity. True False
True
If a country's saving rate declined, then other things the same, in the long run, the country would have lower productivity and lower real GDP per person. True False
True
In the long run, the higher saving rate leads to a higher level of productivity and income but not to higher growth in these variables. True False
True
Japan's status as a rich nation is attributable to international trade, but not to Japan's domestic quantities of natural resources. True False
True Feedback: Correct. Natural resources are not necessary for an economy to be highly productive in producing goods and services. Japan, for example, is one of the richest countries in the world, despite having few natural resources. International trade makes Japan's success possible. Japan imports many of the natural resources it needs, such as oil, and exports its manufactured goods to economies rich in natural resources.
