Long-Run Economic Growth
What Determines the Rate of Long-Run Growth?
Labor productivity The quantity of goods and services that can be
produced by one worker or by one hour of work.
Increases in Capital per Hour Worked
Capital Manufactured goods that
are used to produce other goods
and services.
Technological Change
Economic growth depends more on technological change
than on increases in capital per hour worked.
Technological change is an increase in the quantity of
output firms can produce using a given quantity of inputs.

The Role of Technological Change in Growth
Between 1960 and 1995, real GDP per capita in Singapore grew
at an average annual rate of 6.2 percent. This very rapid growth
rate results in the level of real GDP per capita doubling about
every 11.5 years.
In 1995, Alywn Young of the University of Chicago published an
article in which he argued that Singapore’s growth depended
more on increases in capital per hour worked, increases in the
labor force participation rate, and the transfer of workers from
agricultural to nonagricultural jobs than on technological change.
If Young’s analysis was correct, predict what was likely to happen
to Singapore’s growth rate in the years after 1995.

Saving, Investment, and the Financial System
The Macroeconomics of Saving and Investment
Y = C + I + G + NX
I = Y − C − G - NX
Sprivate = Y + TR − C − T = Y - (T -TR) - C
T - TR = Net taxes
Spublic= (T − TR) − G

S = Sprivate
+
Spublic
or
S = (Y − (T - TR) − C) + ((T − TR) − G)
or
S = Y − C − G = I + NX
So, we can conclude that total saving must equal total
investment:
I = S - NX
- NX = Capital Inflows
