$5.$ Suppose that the yield curve shows that the one$-$year bond yield is $3$ percent, the two$-$year yield is $4$ percent, and the three$-$year yield is $5$ percent. Assume that the risk premium on the one$-$year bond is zero, the risk premium on the two$-$year bond is $1$ percent, and the risk premium on the three$-$year bond is $2$ percent. What are the expected one$-$year interest rates next year and the following year?
