23 years

A
Which of the following pairs of terms refer to the same thing?
"capital" and "physical capital"

-5%
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
Given that a country's real output has increased, in which of the following cases can we be sure that its productivity also has increased?
The total number of hours worked stayed the same or the total number of hours worked fell
If there are constant returns to scale, the production function can be written as
Y/L= A F(1,K/L,H/L,N/L)
Outward oriented policies
allow countries to take advantage of gains from trade, have generally led to high growth for the countries that pursued them, and receive widespread support from economists
Based on the available evidence, the existence of well-established and well-enforced property rights appears to be associated with
an enhanced standard of living
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
Other things the same, when an economy increases its saving rate
consumption falls now and production rises later
If your firm's production function has constant returns to scale, then if you double all your inputs, your firm's output will
double but productivity will not change
Property rights give people the ability to
exercise authority over the resources they own
Other things equal, relatively poor countries tend to grow
faster than relatively rich countries; this is called the catch-up effect
If an American-based firm opens and operates a new clothing factory in Honduras, then it is engaging in
foreign direct investment
In the 1800s, Europeans purchased stock in American companies that used the funds to build railroads and factories. The Europeans who did this engaged in
foreign portfolio investment
Productivity is defined as the quantity of
goods and services produced from each unit of labor input
Over extended periods of time, population growth
has uncertain effects on the standard of living
According to research by Robert Fogel, people in Britain grew taller because of
higher caloric intake. This increase in height is associated with higher productivity
Matt is going to college to become a pharmacist. What he learns about existing information increases
human capital but not technological knowledge
Suppose Japanese-based Toshiba Corporation builds and operates a new computer factory in the United States. Future production from such an investment will
increase US GDP more than it increases US GNP
If your firm's production function has constant returns to scale and you increase all your inputs by 60%, then your firm's output will
increase by 60%
"When workers have a relatively small quantity of capital to use in producing goods and services, giving them an additional unit of capital increases their productivity by a relatively large amount." This statement
is consistent with the view that capital is subject to diminishing returns
The slope of the production function with capital per worker on the horizontal axis and output per worker on the vertical axis
is positive and gets flatter as capital per worker rises
Other things the same, a country that increases its saving rate increases
its future productivity and future real GDP
Human capital is the
knowledge and skills that workers acquire through education, training, and experience
For a given year, productivity in a particular country is most closely matched with that country's
level of real GDP divided by hours worked over that year
Educational attainment tends to be
low in countries with high population growth
The average income in a rich country is
more than 10 times that in a poor country. Further, people in rich countries have longer life expectancy.
The inputs into production of goods and services that are provided by nature, such as land, rivers, and mineral deposits are called
natural resources
In the equation for the production function Y/L represents
productivity
The one variable that stands out as the most significant explanation of large variations in living standards around the world is
productivity
Suppose that a new government is elected in Eurnesia. The new government takes steps toward improving the court system and reducing government corruption. The citizens of Eurnesia find these efforts credible and outsiders believe these changes will be effective and long lasting. These changes will probably
raise real GDP per person and productivity in Eurnesia
A nation's standard of living is best measured by its
real GDP per person
Over the last ten years productivity grew faster in Mapoli than in Romeria while the population and total hours worked remained the same in both countries. It follows that
real GDP per person grew faster in Mapoli than in Romeria
Historically, the market prices of most natural resources (adjusted for inflation) have
remained stable or decreased
Thomas Malthus's predictions turned out to be wrong due to
technological advances such as those during the Industrial Revolution
An understanding of the best ways to produce goods and services is called
technology
What is a good gauge of economic progress?
the growth rate of real GDP per person, but not the level of real GDP per person
Ralph is a plumber. Which of the following are included in his human capital?
the knowledge he learned on the job, but not the tools he uses
In an economy wide sense, property rights are an important prerequisite for
the price system to work
In a particular production process, if the quantities of all inputs used double, then the quantity of output doubles as well. This means that
the relevant production function has the constant returns to scale property
What can be measured by the level of real GDP per person?
the standard of living, but not productivity
