stochastic dynamic programming - how to set up bellman and find FOCs












0












$begingroup$


I have a function:



$$ U = mathbb{E} bigg[ sum_{t=0}^{infty} beta^t ln c_t bigg]$$
Where $0<beta<1$ and my constraints are:
$$c_t + k_{t+1} = phi_t Ak_t^{alpha}, 0<alpha<1, k_1 = b_1 in mathbb{R}$$



where $phi_t$ is iid.



Then am I going about the correct way to find the FOCs?



Setting up the bellman we have:



$$ V_t(k_t) = max_{k_t}big{ln (phi_t AK_t^alpha -k_{t+1}) + beta V_{t+1}(k_{t+1}) big}$$



Am I on the right track?
