Euler Equation

 

We consider the same basic maximization problem:

 

   where

as yesterdayfs.

 

Euler equation is

 

 

or

and

 

Given  and , from the second relation, we can get .

 

Then, , , and , from the first relation, we have to find  together with .

 

 can be derived from the second relation given  and  simultaneously.

 

 

 

 

Instead, we keep  as constant in the first relation and we can calculate each

 

from t=0. That is, we solve

 

and

from t=0 starting from  and . We can do the same thing from steady state

 

backwards.
