1. In-Kind and Cash Transfers Consider an individual who derives their utility from housing consumption (h) and non-housing consumption (c): u(c, h) The individual maximizes utility subject to a budget constraint: Pcc + phh = y a) graph the consumer's budget constraint, and a corresponding optimizing consumption bundle (assume that the household consumes a mix of housing and non-housing) • Now suppose that the government provides an in-kind proportional rent subsidy equal to \alpha of the households total housing expense b) write the new budget constraint under subsidy program, and graph the new budget constraint c) plot the corresponding optimizing consumption bundle under the new constraint (assume that the house- hold consumes a mix of housing and non-housing) and label the level of housing consumption $h_{IK}$ • Now suppose instead of providing the individual an in-kind subsidy, the government provides a cash grant equal to the size of the government outlay under in-kind proportional rent subsidy. d) write the new budget constraint under the equivalent cash subsidy program, and graph the new budget constraint e) does the cash grant increase housing consumption by more, less or the same as the in-kind transfer? do you know? f) does the cash grant lead to higher, lower, or the same utility as the in-kind transfer? do you know?

In this problem we consider an equation in differential form $M \, dx + N \, dy = 0$. $(3x^3 - 2y) \, dx + (-(2x + 2y^2)) \, dy = 0$ Find $M_y = -2$ $N_x = -2$ If the problem is exact find a function $F(x, y)$ whose differential, $dF(x, y)$ is the left hand side of the differential equation. That is, level curves $F(x, y) = C$, give implicit general solutions to the differential equation. If the equation is not exact, enter NE otherwise find $F(x, y)$ (note you are not asked to enter C) $F(x, y) = NE$
