Speculators Create Liquidity

Image result for liquidity

Liquidity, in law, is the ease with which an asset can be converted to cash. Real estate is considered an illiquid asset; it can take months to sell a plot of land. An interest in a privately owned company may be liquid or may not -- the question is very context specific. But a stock in a publicly owned and exchange traded company is very liquid -- it can be turned into cash by a call to one's broker.

This is distinct from, although, closely related to, the sense that the word "liquidity" has among economists or in the world of finance. In those worlds it is a market not an asset as such that has liquidity, And the liquidity is in essence the volume of activity.

It is a good thing that markets are liquid (in the finance sense), because it renders the assets involved liquid (in the lawyers' sense) and, all other things equal, one would rather have a liquid asset than an illiquid one.

In discussions of corporate management and accounting, "liquidity" has another sense. It is the ability of an enterprise to pay off its due or soon-to-be-due debts with its current assets. Obviously the accounts receivable office at the firm's counter-parties want cash. They don't want, say, office furniture. So if you don't have cash on hand you (dear CFO) better have highly liquid assets on hand.

All of these related meanings contribute to the significance of the common saying, "speculators provide liquidity."

Consider the corn market. It consists of farmers who have raised corn; commercial buyers who want corn to sell into the retail market; exchanges that mediate the relationship between them. Those are the most obvious participants, anyway. But the corn market also includes a healthy heaping of speculators, betting on the rise or fall they expect on the prices of corn and other commodities.

What good do the speculators do? Well ... they supply liquidity. They make the market deeper, and thus make it easier for the other parties to conduct deals, and even to continue managing liquid enterprises.

Speculation. It's a good thing.

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge.   We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a maj...

Searle: The Chinese Room

John Searle has become the object of accusations of improper conduct. These accusations even have some people in the world of academic philosophy saying that instructors in that world should try to avoid teaching Searle's views. That is an odd contention, and has given rise to heated exchanges in certain corners of the blogosphere.  At Leiter Reports, I encountered a comment from someone describing himself as "grad student drop out." GSDO said: " This is a side question (and not at all an attempt to answer the question BL posed): How important is John Searle's work? Are people still working on speech act theory or is that just another dead end in the history of 20th century philosophy? My impression is that his reputation is somewhat inflated from all of his speaking engagements and NYRoB reviews. The Chinese room argument is a classic, but is there much more to his work than that?" I took it upon myself to answer that on LR. But here I'll tak...

Recent Controversies Involving Nassim Taleb, Part I

I've written about Nassim Taleb on earlier occasions in this blog. I'll let you do the search yourself, dear reader, for the full background. The short answer to the question "who is Taleb?" is this: he is a 57 year old man born in Lebanon, educated in France, who has been both a hedge fund manager and a derivatives trader. He retired from active participation from the financial world sometime between 2004 and 2006, and has been a full-time writer and provocateur ever since. Taleb's writings for the general public began where one might expect -- in the field where he had made his money -- and he explained certain financial issues to a broad audiences in a very dramatic non-technical way. Since then, he has widened has fields of study, writing about just about everything, applying the intellectual tools he honed in that earlier work. As you might have gather from the above, I respect Taleb, though I have sometimes been critical of him when my own writing ab...
