Y
|
Real GDP=Qty of output produced
|
|
L
|
Labor Force
|
|
Y/L
|
Productivity
|
|
K
|
Physical Capital
|
|
H
|
Human Capital
|
|
N
|
Natural Resources-Input
|
|
A
|
Technology Advancement-Not an Input
|
|
Production Function
|
Y = A f(L, K, H, N)
|
|
Productivity Measured per worker
|
Just Divide K H N by L...(A) is not divided by L becuase it is a level not an input
|
|
"A" Outside
|
“A” multiplies the function F so improvements in technology allow more output (Y) to be produced from any given combination of inputs.
|
|
Y
|
Outputs
|
|

|
|

Global Fact of Income 1
|
HUGE differences in GDP/person, or living standards, across countries
|
|
Global Fact of Income 2
|
#2: There is a lot of variation in growth rates of GPD/person across countries
|
|
Rule 72

72 / (growth rate of GDP per person) = # of years for GDP/person to double
ex. |
|
Rule 72 Examples
|
Ex: Mexico’s growth rate = 4.5%. How many yrs will it take for incomes to dbl?
72 / 4.5 = 16 yrs for incomes to double Zimbabwe’s growth rate = -7.7% 72 / -7.7 = -9.35. In 9.35 years, Zimabwe’s income will be cut in half! |
|
Returns to Scale (two types)
|
1. Increasing RTS=Double all inputs & receive more than double output...developing countries
2. Decreasing RTS=Double all inputs & receive less than double output...Developed Countries |
|
A vs. H
|
A=how to produce...shared by many producers
H=Effort to Aquire Knowledge...usually tied to individual who puts forth effort |
|
CRS
|
Constant Returns to Scale...Outputs and Inputs change by same percentage
|

Hans Rosling
|
-Social changes (changes in H, K, L, N, A) precede economic change (Y/L)
-Role of government type & growth -Role of Gov’t & Income Gap (variances in Y/L) -Free trade increases Y/L -Increases in H/L increases in Y/L. -Health (H/L) before Wealth (Y/L) -Income Distribution |
