Based on economists' forecast and analysis, $1-$year Treasury bill rates and liquidity premiums for the next four years are expected to be as follows: r$1=0\mathrm{.}66\%$ E$(2$r$1)=1\mathrm{.}75\%$ E$(3$r$1)=1\mathrm{.}85\%,$E$(4$r$1)=2\mathrm{.}15\%$ L$2=0\mathrm{.}05\%$L$3=0\mathrm{.}10\%,$L$4=0\mathrm{.}12\%$ using the liquidity premium theory, determine the current$($long$-$term$)$ rates.
