Credit Default Swaps and the Credit Crisis
探讨信用违约互换是否加剧了信贷危机，认为其并非危机主因，场外市场在危机中表现良好，并比较了交易所交易与场外交易的利弊。
Many observers have argued that credit default swaps contributed significantly to the credit crisis. Of particular concern to these observers are that credit default swaps trade in the largely unregulated over-the-counter market as bilateral contracts involving counterparty risk and that they facilitate speculation involving negative views of a firm's financial strength. Some observers have suggested that credit default swaps would not have made the crisis worse had they traded on exchanges. I conclude that credit default swaps did not cause the dramatic events of the credit crisis, that the over-the-counter credit default swaps market worked well during much of the crisis, and that exchange trading has both advantages and costs compared to over-the-counter trading. Though I argue that eliminating over-the-counter trading of credit default swaps could reduce social welfare, I also recognize that much research is needed to understand better and to quantify the social gains and costs of derivatives in general and credit default swaps in particular.
