In period t, a parental household (indexed by i) equipped with human capital hit earns a labour income of wh^i_t, where w > 0 represents a constant wage rate. This household derives utility out of own consumption c^i_t, the number of children nit and their level of human capital h^i_(t+1). Education is provided by teachers who are equipped with the economy’s average level of human capital h^T_t . Human capital per child evolves from one period to another according to h^i_(t+1) =(e^i_t +e ̄)^η(h^i_t)^τ(h^T_t )^(1−τ), 0 < η, τ < 1 (1) where e ̄ > 0 is a constant parameter and e^i_t represents the level of education per child. The households’ utility function is specified as U_t^i = ln(c^i_t) + γ[ln(n^i_t) + βln(h^i_(t+1))] (2) with γ,β > 0. Raising one child to adulthood requires a share of 0 < z < 1 units of time. Moreover, education is subsidised at a rate 0 ≤ s_e < 1, such that education costs per child amount to wh^T_t e^i_t(1 − s_e). Solve household i’s optimisation problem and explain the economic rationale of your results.
