Workers today are more productive because they have more physical capital per worker as well as more education.

The source of money for investment is

savings

True or False? South Korea is part of the East-Asian miracle because it has experienced rapid technological progress, high rates of savings and investment in physical capital, and improvement in human capital.

True

The book published by scientists in the Club of Rome was

The Limits to Growth

True or False? The most important measure used to determine economic growth is the population size divided by real GDP.

False.
The most important measure of economic growth is real GDP per capita, which is real GDP divided by population size.

business
government

The primary reason for the poor economic performance within sub-Saharan Africa is

political instability

True or False? Burning fossil fuels releases carbon dioxide into the atmosphere which creates a greenhouse effect, which causes climate change.

True

The key statistic used to track economic growth is

real GDP per capita

Physical capital per worker increased by 4%. How much has growing physical capital per worker contributed to productivity growth?

This raises productivity by 0.5 x 4%, which is 2%.

The U.S. became the world's leading economy in part because

American firms were among the first to make research and development a part of their operations.

True or False? Between 1980 and 1994 real GDP per capita actually decreased in sub-Saharan Africa.

True

Economists believe that likely limits to economic growth will arise mainly because of:

environment degradation

If an amount doubles in 10 years, its growth rate must be

According to the Rule of 70,

70/growth rate = # of years needed for amt to double. If growth rate = 7%, amt doubles in 10 years.

True or False? During the twentieth century in the U.S., most of the growth in real GDP per capita was due to increases in productivity.

True

The sources of savings are

foreign and domestic households

The only country in Latin America that has achieved rapid economic growth is ______.

Chile

Long-run economic growth is _________ if it can continue in the face of limited natural resources and the impact of growth on the environment.

sustainable

Diminishing returns to physical capital may disappear if:

technology improves

True or False? If the government imposes tariffs on imports, it will raise productivity growth.

false

Southland has a real GDP per capita of $5000, which is growing at 10%. Northland has a real GDP per capita of $10,000, which is growing at 5%. Real GDP per capita for the two nations will converge in ______ years.

14 years.
Southland: 5,000 -> 10,000 in 70/10 = 7 years. So 20,000 in 14 years.
Northland: 10,000 -> 20,000 in 70/5 = 14 years.

negative externality

A cost that individuals or firms impose on others without having to offer compensation.

*In the absence of government intervention, individuals and firms have no incentive to reduce negative externalities.

Sustained economic growth occurs only when

the productivity of workers increases steadily

True or False? Public health measures, such as clean water and disease control, are examples of infrastructure.

True

True or False? Diminishing returns to physical capital means that real GDP per worker eventually decreases as physical capital per worker increases.

False.
Diminishing returns to physical capital means that the increase in real GDP per worker is smaller, but still positive, as more physical capital per worker is added.

Real GDP in the country of Esperano has grown at 4% per year for the last 30 years. The labor force has grown at 1% per year and the quantity of physical capital has grown at 5% per year. A 1% increase in average physical capital per worker (all other things being equal) raises productivity by 0.5%. Average education has not changed. How much has technological progress contributed to productivity growth?

Productivity increased by 3% and the growth of physical capital contributed 2%, so technology contributed 1%.

so 1%

False.

True or False? A robot that can perform surgery is an example of human capital because it is a machine that can do the same task as a human.

False.
A robot is physical capital. Human capital relates to the education and experience of the labor force.

The key statistic used to track economic growth over time is

real GDP per capita

7

Over the past century, the annual rate of growth of per capita GDP has averaged

1.8%

Using the Rule of 70, we can determine that, if real GDP per capita is growing at a rate of 1.6 percent per year, it will double in approximately _______ years.

44

The primary ingredient necessary for long-run economic growth is

rising labor productivity

The improved capabilities of labor arising from education and knowledge are known as

human capital

An aggregate production function will show how productivity depends on

technology, human capital, physical capital

Diminishing returns to physical capital may disappear if we

also increase the level of technology and human capital

Total factor productivity is a measure of

the amount of output that can be produced with a given amount of factor inputs.

Growth accounting allows us to calculate

the effects of greater physical and human capital on economic growth.

Over the period of 1948 to 2007, American labor productivity rose by

2.3% per year

an international comparison today shows that

natural resources are less important than human and physical capital in determining productivity.

In the time since Malthus wrote his book

advances in technology and increases in physical capital have more than offset the effects of a rising population.

Countries that add significantly to their stock of physical capital

experience diminishing marginal returns to labor

Typically, countries in which investment accounts for a large share of GDP

have a high domestic savings rate

R&D is paid for by

combo of private and government funds

Economist Paul Romer described R&D as

the creation of improved instructions.

New growth theory asserts that technological change

responds to economic incentives

The standard of living in the United States has increased over time because

there has been long-run economic growth.

Long-run economic growth depends primarily on:

productivity

A sustained increase in per capita GDP arises from

higher productivity

As the U.S. workforce becomes more educated:

there is increase in human capital

what is not a determinant of productivity?

level of wages

When more physical capital is added to the production process but the number of workers remains constant:

amount of output per worker increases, but at a decreasing rate

Total factor productivity measures the economic effect of:

technological progress

The inputs of the aggregate production function are

physical capital per worker, human capital per worker, and technology

The evidence seems to suggest that innovations in information technology made the most significant contributions to productivity:

when they changed the way office work was done

In order to increase its stock of physical capital, an economy must:

engage in investment spending

A healthy banking system can contribute to the growth of an economy by

providing a way for savings to be channeled into business investment

education enhances economic growth by

adding to the stock of human capital.

what can enhance productivity and growth?

Governments that provide and maintain a good infrastructure for economic activity

convergence hypothesis asserts that

relatively poor countries will have higher growth rates than prosperous countries will.

Those who question whether long-run economic growth is sustainable emphasize that

rates of pop growth are too high

some have argued that the current approach to sustained growth is flawed and it assumes

infinite growth

growth rates productivity + work week hours (manufacturing)

inverse relationship
productivity increases
as number of hours worked per week decreases

growth rates depend on

changing pop
increasing tech
more capital per worker

what made ireland turn things around for the better?

good infrastructure and human capital

sources of long run growth

1. (labor) productivity = output per worker
2. phys capital = human-made resources (buildings, machines)
3. human capital = improvement in labor created by the education + knowledge embodied in the workforce
4. technology = technical means for the production of goods + services

how can a big time CEO make the same as a teacher?

higher quality degrees hold more total welfare than lower quality degrees.
some degrees have more market based welfare than others.

aggregate production function

hypothetical function that shows how productivity (real GDP per worker) depends on the quantities of physical capital per worker + human capital per worker as well as the state of tech

aggregate production function

Y/L = f(K/L, H/L, T)
Y = F(T,K,Z,L)

Y = Real GDP
T = Technology
K = Physical Capital
Z or H = Natural Resources
L = Labor Hours

recent example of APF

GDP per worker = T x (Physical capital per worker) ^0.4 x (Human capital per worker)^0.6

where T reps an estimate of the level of tech and each year of education raises workers' human capital by 7%

why did china grow faster than india?

china's higher levels of investment spending, which raised its level of phys capital per worker faster than india's

faster chinese technological progress

aggregate production function exhibits

diminishing returns to physical capital when holding the amount of human capital and the state of technology fixed, each successive increase in the amount of physical capital leads to a smaller increase in productivity

as physical capital per worker rises, what happens to real GDP per worker?

it becomes smaller

a reasonable increase in physical capital per worker will/won't reduce productivity

won't

due to dim returns, at some point increasing the amt of phys capital per worker no longer produces an economic payoff

growth accting

estimates the contrib of each major factor in the agg prodxn fxn to econ growth

each 1% rise in physical capital per worker, holding human capital and tech constant, raises output per worker by

1/3 of 1% or 0.33%

total factor productivity

amount of output that can be achieved with a given amount of factor inputs

technological progress effect on productivity curve

shifts it upward = increase in real GDP per worker

what are farmland and canals considered as?

capital NOT LAND

IT Paradox

new tech doesn't yield its full potential if you use it in old ways

what are two crucial ingredients in long run econ growth

1. political stability
2. protection of property rights

*excessive gov intervention can decrease econ growth

East Asia - why so good?

high savings + investment spending rates
education emphasis
adoption of tech advances from others

Latin America - why so bad?

poor education
political instability
irresponsible gov policies

sub Saharan Africa - why so ugly?

severe instability
war
poor infrastructure (affecting public health)

what region's growth rates have converged?

advanced countries NOT the world

what makes long run growth sustainable?

if it can continue in the face of the limited supply of natural resources and the impact of growth on the environment

over the course of the 20th century, real GDP per capita in the U.S. increased by how much?

5 fold

physical capital

all human-made goods that are used to produce other goods and services; tools and buildings

human capital

the knowledge and skills that workers acquire through education, training, and experience

aggregate production function

relationship that tell us how real GDP changes as the quantity of labor changes when all other influences of production remain the same

aggregate production function formula

Y = F(T,K,Z,L)
Y = Real GDP
T = Technology
K = Physical Capital
Z = Natural Resources
L = Labor Hours
