Topic 8 Economic Growth Part II
  • Growth of potential GDP drives long run economic
    growth.
  • Ways to accelerate growth of potential GDP
  • The Convergence Hypothesis

Actual and Potential GDP in the US
  • Data show actual GDP fluctuates up and down
    around potential GDP. Thus, long term economic
    growth rate (_____________________________________
    ________) is roughly the same as the potential
    GDP growth rate.

The average economic growth rate over a long
period
  • An objective of macroeconomic policy is to have
    __________________________________.

high potential GDP growth rate
5
What do we learn from the experiment?
technology
  • The higher the growth rate of ___________,
    _________, ____________, or ________________, the
    higher the growth rate of potential GDP
  • Higher ________________ growth is however not
    desirable because the higher it is, the lower the
    growth rate of _____________.

capital
human capital
labor (population)
labor (population)
GDP per capita

An Empirical Observation

An alternative measure of economic growth
  • Labor Productivity is the amount of output a
    worker turns out in an hour of work.
  • It is a proxy of the economys well being.
  • Y/N (L/N) x (Y/L)
  • ________________________x_____________
  • ____________ Total hours of labor input x
    ___________________
  • What are the factors that accelerate growth of
    labor productivity?

GDP per capita
Work length
Labor productivity
Potential GDP
Labor productivity

Ways to Accelerate Growth of Potential GDP?
  • Capital Factors that stimulate investment can
    accelerate growth rate of capital stock.
  • A myth before the end of the cold war The leap
    forward strategy of economic development.
  • Russia
  • China
  • India

Ways to Accelerate Growth Rate of Potential GDP?
education
  • Human capital Improving ___________ or
    ___________________can accelerate the growth rate
    of human capital.
  • Technology More ____________, _____________,
    ________________, or _______________________
    ____________ accelerates technology progress.
  • ______________ creates new technology.
    ________________ absorbs existing technology.
  • USA cannot grow as fast as China. Why?

Convergence Hypothesis
  • Convergence Hypothesis is an empirical phenomena
    that the difference/ratio of GDP per capita
    between rich and poor countries tend to shrink
    over time.
  • But many poor countries have not joined the
    convergent club.
