period 2. In period 1, households receive an endowment Y
households receive profits from firms that they own. Households pay lump-

sum taxes Ti and T2 in periods 1 and 2, respectively, and can save at the
interest rate r. Firms borrow funds in period 1 to invest I1 units of goods

Expert Answer

Step 1

(a) Household’s budget constraint in period 1 is:

C1 + S1p = Y1 – T1

Household’s budget constraint in period 2 and the intertemporal budget constraint of the household is:

Step 2

(b) Now to find the optimal consumption level we will equate the slope of budget constraint (BC) with the marginal rate of substitution (MRS).

Slope of BC = (1+r)

MRS = U’C1 / U’C2

          = (1/C1) / (1/C2)

               = C2 / C1

Equating the ...
