Abstract
This paper determines which market among credit derivative market, corporate bond market and equity market is the main forum where price discovery occurs. When credit risk becomes an important issue in the financial market, most securities are traded under credit risk consideration. It is interesting to find out where the credit risk information embeds in most. This paper tries to find the proxies for prices of credit risk in these three markets. Then uses vector error correction model to investigate which marker has the most information credit risk. Results indicated that equity market contributes most information of credit risk. We also find the corporate bond market is minor market where price discovery takes place. After dropping this market, we still find that equity market is the main forum of price discovery. Besides, credit derivative market contributes more information when the entities have higher rating, and equity market contributes more when the entities have lower rating.
