Many economists now deemphasize capital accumulation as a source of growth because: -capital accumulation no longer affects growth. -capital accumulation alone does not necessarily lead to growth. Correct -the value of the capital stock no longer depends upon technology and needs of society. -capital has been defined so narrowly that it has become a less useful concept.

Correct d. quickly since the increase in saving will permit more rapid technological progress.

c

Compounding means that changes in living standards depend: A) only on the initial level of income. B) only on the accumulation of changes in income since the initial year. C) on both the initial level of income and the accumulation of changes in income every year since the initial year. D) on neither the initial level of income nor the accumulation of changes in income since the initial year.

d

Some economists argue that well-functioning capital markets that allow funds to move from those who have but do not need funds to those who need but do not have funds,are essential for rapid economic growth. Well-functioning capital markets are anexample of: A) human capital. B) entrepreneurship. C) physical capital. D) growth-compatible institutions.

d

When the supply of loanable funds (savings) increases, the interest rate _____ and the quantity of loanable funds demanded (investment) ________

falls increases

According to new growth theory, the primary source of growth is capital.

false

Diminishing marginal productivity implies that a proportional increase in all inputs will produce a less than proportional increase in output.

false

potential output

highest amount of output an economy can produce from existing producing processes and resources

Markets help to promote growth by:

increasing specialization and division of labor

when below potential output, an economy is operating ______ its PPC

inside

social capital

is the habitual way of doing things that guides people in how they approach production

per capita growth

means the country is producing more goods and services per person % change in output − % change in population

Learning by doing

meant to improve the methods of production through experience overcomes the law of diminishing marginal productivity because it increases the productivity of workers In the new growth theory, growth potential is unlimited and can accelerate over time.

does capital accumulation lead to growth

not necessarily -capital may become obsolete -includes human capital + social capital also

at potential output, an economy is operating ______ its PPC

on

short run focus is on how to get the economy ...

operating at potential

growth focuses on shifting ______ the PPC

out

productivity

output per unit of input

disadvantages of growth

pollution resource exhaustion destruction of natural habitat

human capital

skills that workers gain from experience, education, and on-the-job training

what increases productivity + growth

specialization division of labor

Law of diminishing marginal productivity

states that as more and more of a variable input is added to an existing fixed input, eventually the additional output produced with that additional input falls

long-run growth focuses on

supply -assumes demand is sufficient to buy whatever is supplied

Say's law

supply creates its own demand -people work and supply goods b/c they want other goods

Unlike Classical growth theory, new growth theory emphasizes the importance of: .

tech

entrepreneurship

the ability to get things done using creativity, vision, willingness to accept risk, and a talent for translating vision into reality

specialization

the concentration of individuals on certain aspects of production

classical growth model

the more capital an economy has, the faster it will grow savings -> investment -> increase in capital -> growth

division of labor

the splitting up of a task to allow for specialization of production

technology

the way we make goods and supply services. -Changes fuel growth. -Advances shift the production possibility curve outward by making workers more productive.

New growth theory

theory that emphasizes the role of technology in the growth process tech advance -> investment -> further tech advance -> growth

per capita output

total output / total population

t or f growth in income improves avg living standards

ture

does growth raise the incomes of the poor

yes -has reduced the number of hours the average person needs to work to buy consumer goods

General policies that are good for growth include

•Encouraging saving and investment. •Formalizing property rights and reducing bureaucracy and corruption. •Providing more of the right kind of education. •Promoting policies that encourage technological innovation. Promoting policies that allow taking advantage of specialization

rule of 72

•The number of years to double income 72/ growth rate. •If France's income grows at 3% per annual rate, it will double in 24 years (72/3).
