K-EDe^-γw_T-1-π_T-1 r_T-1 e^-γπ_T-1 μ_T-1 e^-γπ_T-1 σ_T-1^22 e^-γc_T-1 e^-γδq_T-1 e^-γq_T-1 α_T-1 e^-γq_T-1 β_T-1^22使用一阶最优化准则求π_T-1

根据一阶最优化准则，对π_(T-1)求偏导数，并令其等于0，可以得到：

∂K-E/∂π_(T-1) = -γ(w_(T-1) - π_(T-1) r_(T-1)) e^(-γ(w_(T-1)-π_(T-1) r_(T-1))) e^(-γπ_(T-1) μ_(T-1) ) e^(-γπ_(T-1) σ_(T-1)^2/2) = 0

化简后可得：

w_(T-1) - π_(T-1) r_(T-1) - μ_(T-1) - σ_(T-1)^2/2 = 0

移项可得：

π_(T-1) = (w_(T-1) - μ_(T-1) - σ_(T-1)^2/2) / r_(T-1)

因此，使用一阶最优化准则求π_(T-1)的结果为：

π_(T-1) = (w_(T-1) - μ_(T-1) - σ_(T-1)^2/2) / r_(T-1)
