Problem
Refer to the below quote from the January (1992) issue of "Bond Week"
"Issuance of callable long-term bonds dropped off further last year as interest rates fell, removing the incentive for many issuers to pay extra for the provision, said Street capital market officials. . . . The shift toward noncallable issues, which began in the late 1980s, reflects the secular trend of investors unwilling to bear prepayment risk and possibly the cyclical trend that corporations believe that interest rates have hit all-time lows."
Answer the below questions.
• What "incentive" is this article referring to in the first sentence of the excerpt?
• Why would issuers not be willing to pay for this incentive if they feel that interest rates will continue to decline?
• Explain how an increase in expected interest-rate volatility can affect the value of a callable bond.
