"The Illusion of the Perpetual Money Machine"

15.12.12

 

We argue that the present crisis and stalling economy continuing since 2007 are rooted in the delusionary belief in policies based on a "perpetual money machine" type of thinking. We document strong evidence that, since the early 1980s, consumption has been increasingly funded by smaller savings, booming financial profits, wealth extracted from house price appreciation and explosive debt. This is in stark contrast with the productivity-fueled growth that was seen in the 1950s and 1960s. This transition, starting in the early 1980s, was further supported by a climate of deregulation and a massive growth in financial derivatives designed to spread and diversify the risks globally. The result has been a succession of bubbles and crashes, including the worldwide stock market bubble and great crash of October 1987, the savings and loans crisis of the 1980s, the burst in 1991 of the enormous Japanese real estate and stock market bubbles, the emerging markets bubbles and crashes in 1994 and 1997, the LTCM crisis of 1998, the dotcom bubble bursting in 2000, the recent house price bubbles, the financialization bubble via special investment vehicles, the stock market bubble, the commodity and oil bubbles and the debt bubbles, all developing jointly and feeding on each other. Rather than still hoping that real wealth will come out of money creation, we need fundamentally new ways of thinking. In uncertain times, it is essential, more than ever, to think in scenarios: what can happen in the future, and, what would be the effect on your wealth and capital? How can you protect against adverse scenarios? We thus end by examining the question "what can we do?" from the macro level, discussing the fundamental issue of incentives and of constructing and predicting scenarios as well as developing investment insights.

As such, the constitution of
the financial markets is fundamentally changed from an ensemble of individual networks to a closely linked network-of-networks configuration. Very recent research in network theory has shown that, when different networks become  linked, the overall structure loses resilience. Indeed, due to  diversification, there are less minor events but, due to the  stronger coupling, there are more catastrophic events.

Using models specifically designed to quantify the degree of  endogeneity (called “reflexivity” by Georges Soros) in the  markets, defined as the fraction of transactions that are triggered internally or are self-excited, like aftershocks of an  earthquake, and that are not the result of some new external information, we recently quantified that this degree of reflexivity increased from 30% in the 1990s to at least 80% as
of today. This proves, in hard numbers, that markets increasingly live a life of their own, disconnected from the real economy, activated by machines and the algorithms that compete to trade in milliseconds, a process also facilitated by massive injections of liquidity and the low interest rate policy operating at a different time scale. As a consequence, the bubbles and crashes, that we have become accustomed to, now develop and evolve increasingly over time scales of seconds to minutes.

(...)

We do not expect that the technological race will provide a stabilization effect, overall. This is mainly due to the crowding of adaptive strategies used by algorithmic agents, which exhibit pro-cyclical properties (for instance via a preference in socalled momentum trading) and a propensity to herd that is even larger than found in human beings. No level of technology can change this basic fact, which is widely documented for instance in artificial worlds populated by software-agents that simulate financial markets on computers. New algorithms that exploit the high volatility periods associated with distress and crashes are been vigorously developed.These are really worrying trends.

William Yeats - "The Second Coming"

15.12.12

Turning and turning in the widening gyre
    The falcon cannot hear the falconer;
    Things fall apart; the centre cannot hold;
    Mere anarchy is loosed upon the world,
    The blood-dimmed tide is loosed, and everywhere
    The ceremony of innocence is drowned;
    The best lack all conviction, while the worst
    Are full of passionate intensity.

    Surely some revelation is at hand;
    Surely the Second Coming is at hand.
    The Second Coming! Hardly are those words out
    When a vast image out of Spiritus Mundi
    Troubles my sight: a waste of desert sand;
    A shape with lion body and the head of a man,
    A gaze blank and pitiless as the sun,
    Is moving its slow thighs, while all about it
    Wind shadows of the indignant desert birds.

    The darkness drops again but now I know
    That twenty centuries of stony sleep
    Were vexed to nightmare by a rocking cradle,
    And what rough beast, its hour come round at last,
    Slouches towards Bethlehem to be born?

"The Elderly Master: Unarmed Techniques from Fabian von Auerswald"

15.12.12

 

Fabian von Auerswald was a German Renaissance master ofRingen (wrestling). In 1537, at the age of 75, he completed a beautifully illustrated treatise on wrestling called Ringer kunst: funf und Achtzig Stücke (The Art of Wrestling: Eighty Five Techniques). It was published posthumously in 1539. This work was dedicated to the Lord John Frederick, elector of Saxony, and even states that he trained the lord’s sons as well as many of the men of his court. Considering the age of von Auerswald when it was first created, and considering the illustrations show an aged von Auerswald tossing around younger wrestlers, we should all be inspired by the vitality and skill the man must have possessed well into the latest years of his life. It is also notable that the woodcuts were created in the workshop of the famous artist Lucas Cranach. This was an expensive work to produce, and Lord Frederick, as von Auerswald’s patron, clearly felt the elderly master’s expertise was worth the expense.
