先敘述一下問題的相關設定
t
max Σβ u(ct,nt) (ct,nt)def(consumption,labor) 0=<t<∞
st ct+(bt+1-bt)=wt.nt+rt.bt+Πt (b,Π)def(bond,profit)
t t
L=Σβ u(ct,nt)+Σλtβ{ct+(bt+1-bt)-wt.nt-rt.bt-Πt﹜
這裡出現了一個問題 -t t
就是為何λt旁的折現因子不用(1+rt) 反而使用β呢??
在來就是在解這一個Lagrange problem 可得Transversality condition
t
為 lim β*bt*λt=0 這代表不存在Panzi game
t→∞
Panzi game我了解,但不太明白的是為何(λt)要存在這個式子中呢??
想請板上有能的前輩指點迷津 在此先說聲謝謝
