The purpose of this thesis is to study on the stability condition that is most important in the growth theory.
It is convenient, usually, to define a stability condition by the requirement that output and employment be growing at some constant proportional rates and that net saving and investment be a constant fraction of output.
There are two approaches which estimate stability condition.
One is some plausible mechanism to drive the one or more variables among the s(saving ratio), v(capital output ratio), g(the rate of labor force growth) into configuration.
The other (Vintage Model) assumes that the substitution between production factors is made into representing over fairly long periods of time.
The characteristics of Vintage Model are as follows
① Vintage is described by the time invested.
② The production capacity is differentiated
③ By the economic life time with obsolescence, the stability condition is checked, the stability condition of Vintage Model is obtained by changing variable μ in the equation
g+λ=as(1-e^(-μd))
The two approaches are like in respect that the stability condition are obtained, but the latter is more real than the former in the view that the homogenity of capital is excluded.
