Answer:
Default risk premium = 1.9%
Explanation:
r = r* + IP + MRP + DRP + LP
Where, IP is the Inflation premium, MRP = market risk premium, DRP=default risk premium, LP=liquidity risk premium, R* = Real risk free rate
The only factors above which will different in T bond and corporate bond is LP and DRP and others will be same
Corporate bond yield=8.0%
T bond yield=6.0%
LP=0.1%
(8.0%-6.0%)=LP+DRP
DRP = 2.0%-0.1%
DRP = 1.9%
