  • Arsonists Running the Fire Brigade

    Six years ago I hosted my first Thanksgiving in a Dallas high-rise, and my then-90-year-old mother came to celebrate, along with about 25 other family members and friends. We were ensconced in the 21st floor penthouse, carousing merrily, when the fire alarms went off and fire trucks began to descend on the building. There was indeed a fire, and we had to carry my poor mother down 21 flights of stairs through smoke and chaos as the firemen rushed to put out the fire. So much for the advanced fire-sprinkler system, which failed to work correctly.

    Way back in the Paleozoic era (as far as markets are concerned), circa 2003, I wrote in this letter and in Bull's Eye Investing that the pension liabilities of state and municipal plans would soon top $2 trillion. This was of course far above the stated actuarial claims at the time, and I was seen as such a pessimist. Everyone knew that the market would compound at 9%, so any problems were just a rounding error.

  • The Quest for Certainty

    The last two weeks we have been looking at the problems with models. First we touched on what I called the Economic Singularity. In physics a singularity is where the mathematical models no longer work. For example, models based on the physics of relativity no longer work if one gets too close to a black hole. If we think of too much debt as a black hole of sorts, we may understand why economic models no longer work. Last week, in “The Perils of Fiscal Cliff,” we looked at the use of fiscal multipliers by economists in order to argue for or against governmental economic policies. Do you argue for austerity, or against it? There is a model that will support your case, most likely using the same data that your adversary uses.
