Equations

$\max \sum_{t=1}^\infty \delta^t \cdot u(w_t)$

$L = \sum_{t=0}^\infty \sum_{z^t} \beta^t \cdot U(c_t(z^t) \cdot \pi_t (z^t)) + \sum_{t=0}^\infty \sum_{z^t} \lambda_t z^t \cdot \{ z^t \cdot f(k_t (z^{t-1} )) + (1 - \delta) \cdot k_t (z^{t-1}) - c_t (z^t) + k_{t+1} (z^t) \}$

$\$ = \mathrm{wage} \cdot (1 - \mathrm{leisure\ time} )$
