Paul Krugman: I think there are two big structural changes that we'd want to see. One is we need to reduce the role of the financial sector in the economy. We went from an economy in which about 4 percent of GDP came from the financial sector to an economy in which 8 percent of GDP come from the financial sector, and in which at its peak 41 percent of profits were being earned by the financial sector. And there is no reason to believe that anything productive happened as a result of all of that. These extremely highly compensated bankers were essentially just finding new ways to offload risks on to other people.
As I've written, we need a boring banking sector again. All of this high finance has turned out to be just destructive, and that's partly a matter of regulation. But in the political economy there was also a vicious circle. Because as the financial sector got increasingly bloated its political clout also grew. So, in fact, deregulation bred bloated finance, which bred more deregulation, which bred this monster that ate the world economy.
Bill Bradley: As we look at the future, we also have to look at the mistakes policymakers made in the last ten years. It's not news that people are greedy. But we made conscious decisions not to put limits on that natural human impulse. What were the mistakes? In 1999, we allowed investment banks, banks, insurance companies to combine: we eliminated the Glass-Steagall Act, which prohibited commercial banks from operating as investment banks. Why was Glass-Steagall put into law? Because the last time we didn't limit greed we got into trouble, the Great Depression.
The second mistake was in 1999, the explicit decision by the Clinton administration and Congress not to regulate derivatives, in particular credit default swaps. In 2002 they were worth $1 trillion and today they're worth $33 trillion, and that decision not to regulate derivatives created the following sequence: you have mortgages; then a thousand mortgages are packaged and sold as a mortgage-backed security; a thousand mortgage-backed securities are packaged and sold as a collateral debt obligation [CDOs]; then a thousand collateral debt obligations are packaged and sold as a CDO squared; and insuring each one of those bundles are credit default swaps, which are a part of that $33 trillion. And our government deliberately decided not to regulate this chain of investments.
