Credit default swap (CDS)
1) What is a credit default swap (CDS)? Consider the cash-flow pattern of the CDS in Exhibit 2 of From free lunch to black hole: Credit Default Swaps at AIG Can you set up a trading strategy using long and short positions of the default-free floating rate bond and the defaultable floating rate bond that replicates the cash flow pattern of the CDS? Given the coupon rate on the defaultable floating rate bond, can you determine the CDS rate based on the law of one price?

Sample Answer
1a. Credit Default Swap (CDS):
A CDS is a financial derivative contract where one party (protection buyer) pays a premium to another party (protection seller) in exchange for protection against the default of a specific underlying asset (reference entity). If the reference entity defaults, the protection seller compensates the protection buyer for the notional amount of the contract.
1b. Cash Flow Replication:
The cash flows of a CDS can be replicated using a combination of long and short positions in the default-free and defaultable floating-rate bonds with the same maturity as the CDS.
