max s.t. Eo t=0 3² u (Cr₁ Ft) P¿C₂ + B₁ + M₁ = (1 + r²₁) B₁-1 + (1+1) Mt-11 where C, is real consumption at time t; M₁/P, is real money balances (M, is money holdings and P, is the price level); B, is bond holdings, which earn a gross rate of return (1+r); money holdings earn a gross rate of return (1+r). The representative household also enjoys utility from holding real money balances. In this economy, the household chooses sequences for consumption, {C}, and real money balances, {M/Po a. Obtain the first-order conditions for the maximization of the household problem (hint: divide the period-t budget constraint by P, before maximizing). b. Assume now that the utility function is Cobb-Douglas in consumption and real money balances, i.e., 1-a u(C₁)C(M)¹ where 0<a<1 You have data for real consumption, real money balances, the price level, and for the short-term interest rates on bonds and money balances. Your objective is to estimate 3 and a by GMM. Derive all the steps for the estimation, presenting the moment conditions and the objective function for the estimation. Discuss identification. max s.t.
