Intro

A corporate bond with $20$ years to maturity yields $7\mathrm{.}9\%$ and has a liquidity

premium of $1\mathrm{.}4\%.$ The real short$-$term risk$-$free rate is $1\%$ and the average

expected inflation rate over the next $20$ years is $2\%.$ The maturity risk premium is

expected to be ${0\mathrm{.}001}^{**}T,$ where $T$ is the number of years to maturity.
