Assumptions of the Solow model
countries produce and consume on homogenous good- not trade
Technology is exogenous
Capital accumulation equation
K=sY-dK
or accumulation= gross investment- depreciation
What do the Solow diagram curves represent
sy is investment per person
(n+d)k = amount of new investment per person required to keep the amount of capital per worker constant
What does the difference in the two curves represent Solow diagram
The change in the amount of capital per worker.
When this is positive capital deepening is occurring
When this is 0 but actual stock is increasing this is capital widening (population growth)
Capital deepening
An increase in capital per worker
