http://www.informationarbitrage.com/2008/03/discontinuous-t.html I grew up in a time when markets were considered to be "continuous." Portfolio insurance. Robert Merton's 1987 treatise Continuous-Time Finance. Liquidity was presumed to be available. And while markets could and did gap due to an event, new information, etc., it could and would clear with transactions taking place at the new level. The financial markets, through price discovery in the presence of liquidity, conveyed valuable information that could be used for both security selection and asset allocation. The field of financial economics, as such, was predicated upon the existence of bids and offers and, therefore, liquidity. And this phenomenon was assumed to persist across time.
But this is not the world I observe today; quite the contrary. Price movements are not only discontinuous, but the notion of liquidity across time as traditionally assumed simply does not exist. Something has happened to rock the prevailing academic paradigm. Have the experiences of the past six months essentially blown a hole through the heart of modern financial theory?
Today we live in a world fraught with risks that we barely understand, risks that modern financial theory doesn't have great answers for. A new model is needed that incorporates the effects of discontinuity as an outgrowth of, among other things:
- Complexity - structured securities, derivative instruments;
- Interdependency - widely disseminated holdings that can pollute portfolios globally, hundreds of trillions in counterparty exposures;
- Intermediary errors - ratings that don't reflect the risks, financial institutions with weak control environments and poor risk management practices; and
- Bad actors - originators, underwriters, traders and managers with mis-aligned motives.
Global systemic crisis - End of 2008: Pension funds go off the rails
According to LEAP/E2020, by the end of 2008, a formidable debacle will affect pension funds all over the world, endangering the entire system of capital-based pensions. This financial calamity will bear a particularly dramatic human dimension because it will come at the precise moment when the first wave of baby-boomers phase out of the labour force in the US, EU and Japan: pension fund revenues are collapsing at the very moment when they should be making their first large series of payments to pensioners. In this 23rd edition of the GEAB, our team anticipates the evolution of the upcoming pension fund crisis, details which countries are the most exposed (in particular in Europe) and provides a number of operational and strategic recommendations to face the situation.
