Q. Assume you are a typical consumer and expect to work for 40 years (from this point onward) and to live for 10 years beyond superannuation. Suppose as well that you have perfect foresight, and, if necessary, have the ability to borrow to support future consumption (i.e., you have no liquidity constraints). Explain how much does consumption change this year in absolute dollars ($ ΔC) as a result of a $5,000 annual tax cut to your income, if the tax cut:

A. is permanent, and will begin immediately (this year)?

B. will last only for the current year (i.e., a 1-year temporary tax cut)?
