1. Compare the following concepts as they relate to Macroeconomic consumption and savings: I. Autonomous Consumption and Induced Consumption II. MPC and MPS III. Linear MPC and Non-Linear MPC IV. Saving and Dis-saving V. Permanent Income and Transitory Income VI. Liquidity constraints and Buffer Stocks 2. In developed countries the phenomenon of population aging is happening because of longer life expectancy as well as lower birth rates and lower population growth rates. I. Explain how the life-cycle theory can be used to deduce that while longer expected life increases individual and aggregate savings, a lower population growth rate may increase per capita saving in the short run but reduces it in the long run. II. How does the LC theory suggest that immigration from developing countries maybe favorable for increasing aggregate consumption and savings? 3. In Pakistan there is currently a pensions crisis because the government did not plan pensions of public sector employees efficiently. In developed countries like the US, where people plan their own pensions this planning for retirement requires a lot of effort, forward thinking and knowledge of financial opportunities. Even then pensions are never completely secure in the US. I. Examine the Pension Crisis from perspective of Permanent Income Hypothesis and its modern versions to explain the possible causes of this crisis. II. Related to causes identified in Part I of this question, suggest solutions to the pension crisis in Pakistan
