Answer: D. The risk premium on long-term corporate bonds has exceeded the risk premium on long-term government bonds.
Explanation:
It has been shown that between 1926 and 2015, the risk premium attached to long term corporate bonds is more than those of comparable government bonds and this is supported by financial theory.
Government bonds are traditionally meant to be possess less risk because they are backed by the full faith of the government. They will therefore posses a lower risk premium (risk premium is the extra amount paid on a bond to compensate for risk) than corporate bonds because they have less risk than corporate bonds.
