Robert Waldmann There seems to be a widespread view that the US experience with deregulation has been mixed. Financial deregulation was a disaster, but airline deregulation and telecoms deregulation were OK (except for how crowded airports are and irritating advertisements by competing phone companies). What is this “telecoms deregulation” of which you speak. I absolutely […]
Robert Waldmann I think it is not clear to all readers why I assert that in the simplest possible model of financial markets all agents will invest proportionally in all tranches of all CDOs. I’m not sure I can present even the simplest model in plain ascii. Also the model is very simple and you […]
Robert Waldmann Senator Mark Warner said something about derivatives reform. I kept reading a version of what he said which seemed implausible to me. I had trouble finding a transcript or video of him speaking. In the end very beginning but I’m an idiot and didn’t notice: I found it. It confirms my suspicions.Warner is […]
Robert Waldmann claims that, after the invention of the mortgage based security, which clearly served to diversify risk, there have been three main purposes : weakening the effects of prudential regulations, weakening the effects of prudential charters and making balance sheets look better.

Robert Waldmann Alex Tabarrok wrote In Too Big To Save Robert Pozen gives a clever example, based on an excellent paper by Coval, Jurek and Stafford, which explains both the lure of structured finance and why the model exploded so quickly. Suppose we have 100 mortgages that pay $1 or $0. The probability of default […]
“Liquidity” is another magic word. I like it rather less than “friction.” In the debate on financial regulatory reform opponents of tight regulations use the word liquidity as a magic spell which, they hope, will make all inconvenient evidence and arguments go away (no links my claim is like saying the Sun emits light). The […]
Robert Waldmann John Q. Policymaker is driving a minivan. Maynard Keynes is in the passenger seat, Ed Prescott and Robert Lucas are in the second row of seats and Eugene Fama and John Cochrane are in the back seats. John Q: We are heading for a cliff !Maynard: slam on the brakes. Prescott: I don’t […]
Robert Waldmann Isaac Newton inspired many people to try to be the Newton of various fields. Unfortunately many tried the shortcut of using the same words as Newton but changing their meanings. This meant that those words had high status, because of Newton, but nothing to do with Newton’s success in fitting facts. One such […]
