A Three-Period Economy. Rather than the two-period consumption-savings model econ- omy we have been developing in class, consider a three-period model that is analogous to the two-period model. (a) Derive the lifetime budget constraint (LBC) for the three-period economy. Define any new notation you introduce, and briefly explain the logic you use in deriving your final expression. (b) Provide a brief interpretation of the LBC you derive in part 1. (c) In reality, there are an "infinite" number of periods. Write down the LBC for an infinite-period economy. (No need to be very mathematical - just use what you've learned in class and what you derived above). (d) The Permanent Income Hypothesis states that individuals consider their future life- time earnings when making their current consumption decision. Discuss briefly how the multi-period models we are considering here (regardless of two-period, three- period, n-period, or infinite-period) are consistent with the Permanent Income Hy- pothesis.
