Economics questions 3 and 4 need help with(ITS THE CoMPLETE QUESTION

Consider a two-period economy populated by households with preferences described by the utility function: U = V C1 + V C2 In this economy, the households start period 1 with zero assets (B3 = O) and receive endowments Q1 = 2 and Q2 = 4 in periods 1 and 2, respectively. The economy has free capital mobility, and the world interest rate r*= 0. Calculate the equilibrium levels of consumption and the trade balance in period 1 (C1 and T81).- Consider a two-period economy populated by households with preferences described by the utility function U: 1nC1+1nC2 In this economy, the household starts period 1 with non-zero assets (B3 at 0) and receives endowments Q1 and Q2 in periods 1 and 2, respectively. The economy has free capital mobility, and the world interest rate is ositive (r*>0). Note that this utility function is different relative to the one used inh 4.a)Calculate the equilibrium levels of consumption, the trade balance and the current account in period 1 (CLTBl and CA1) and the equilibrium level of consumption in period 2 (C2). Do not forget to show step by step your algebraic calculations. Explain in detail your economic intuition. No credit without explanation. 4.a)- Suppose that there is an asymmetric permanent shock to the endowments. In particular, assume that the new endowments are equal to (1'1 =Q1+5 and Q'2=Q2+5(1+r*), where Q1 and Q2 are the endowments before the shock. Assume that 5:0 and |5=1. Calculate the change in consumption in period 1 (AC1), the change in consumption in period 2 (AC2), the change in the trade balance in the first period (ATE-1), AND the change current account in the first period (ACA1).
