I need help with question 4(d) and please give me the answer and process

Welcome, Jinjie -... Econ 303 Spring 2020 Professor Eric McDermott Homework 6 OLG problems 1. Given y = 5, y+1 = 10 for all agents/households in this OLG economy, answer the following questions: a. What is cf? b. What is Ct+1 ? c. What is St(the value of savings in period t for each agent)? d. What is rt (in the economy in which there is no transfer)? e. Is the Competitive Equilibrium allocation you just solved for in periods 1 and 2 Pareto optimal? f. Next, suppose in some period t, the government decides to tax the old agents 2.5 units and transfer the 2.5 units directly to the young agents and do so forever after. Is this a Pareto improvement over a world with no government? CH SONG
