The Shortest Day
Everybody knows that the shortest day is the first day of winter, which is usually December 21 in the Northern Hemisphere. (Sorry readers from down-under, but we’re rather geocentric that way.)
So, does the shortest day have the latest sunrise and the earliest sunset? Is there a symmetry between dawn and dusk?
Perhaps you’ve never considered it, but one can find sunrise and sunset times for many cities around the world at http://www.timeanddate.com and probably other sites, too.
When we have more time, we’ll write about how the earth’s axis, which obviously affects the variation in the length of days, is not constant. As we recall, the axis varies between 17 and 22 degrees over rather long cycles; so, the earth spins like a top – but not smoothly; instead it “wobbles.” Does the reader think that the wobbling might affect temperatures and cause some regions to warm and others to cool as the angle changes through time? Yeah, we do, too.
By the way, did the reader know that summer is a few days longer in the Northern Hemisphere than in the Southern Hemisphere? As it turns out, it is longer, but not as intense.
While the earth’s orbit around the sun is an ellipse, the sun is not centered in the ellipse. Summer in the Southern Hemisphere (winter up here) occurs when the earth is closer to the sun; therefore, summer down there is more intense but shorter. (We don’t have a short, non-mathematical explanation for it. Perhaps that’s why our PhD is in the social sciences.)
Now, getting back to our original question, the latest sunrise and earliest sunset do not occur on the shortest day of the year.
The earliest sunsets in the Northern Hemisphere occur right around this date, December 8 (or 7th or so). While the latest sunrises don’t occur until about a week into the new year: around January 5 or so.
For those of us living at roughly the 40th parallel, the sun sets 3 – 4 minutes earlier today than on the winter solstice, and near January 5, is rises about 3 – 4 minutes later in the morning than on the solstice.
Something similar happens in June, but it is not symmetric with the winter. The earliest sunrise occurs around June 13, which is only about a week before the summer solstice, whereas the latest sunset occurs near the end of June, about a week later than it.
And you thought we were just a pretty face who thinks the government bailout a bad idea.
Early Warnings of Excessive Leverage
We were searching our hard drive for a paper, and found a very interesting article that we had saved about the perils of excessive leverage. It is As Funds Leverage Up, Fears of Reckoning Rise from the April 30, 2007, edition of The Wall Street Journal. It is subtitled: Fed and SEC Question Wall Street on Policies; ‘A Mockery’ of Margin.
We’re not sure if an article from the Spring of 2007 is truly an early warning per our title, but “Warnings of Excessive Leverage” doesn’t read as nicely.
In light of very recent events and market events since mid-2007, it is quite interesting and discusses or quotes many familiar names, including, John Paulson (big winner); The Pennsylvania State Employees’ Retirement System (not a big winner); Timothy Geithner (next Treasury secretary); Warren Buffett (not Jimmy Buffett); Kenneth Griffin and Citadel Investment Group (not big winners); Edward Lampert (not big winner, although we do like Lands End at Sears); and many more.
In the article, the reporters paraphrase Janet Tavakoli as follows: “the collateral provided by hedge funds to secure swaps could be difficult to trade… In a market downturn, attempts to unwind such positions could lead to a vicious cycle of selling that would feed on itself…” Sounds reasonable.
We also particularly like this little box that doesn’t appear in the on-line article:
RISK FACTOR
• The Situation: Regulators have grown worried about rising leverage in the U.S. financial system.
• The Players: Hedge funds and the Wall Street firms that provide them with financing are among the biggest contributors to the rise.
• The Bottom Line: No one is sure what will happen with this complex web of borrowing and derivatives in the event of a serious market downturn.
Wow, who would have thunk that there were people way back in 2007 warning of such risks as well as the laxity of risk management. Does this mean that the ongoing liquidity crisis need not have occurred? (By 2007, it was already too late to prevent the mortgage crisis.) Does that mean the destruction of trillions of dollars of wealth could have be prevented and avoided? So, this suggests that it wasn’t (and isn’t) a natural disaster. Wow! And for what?
Auto-makers and Management Fads
In the thirty-five years since the first “energy crisis,” have Chrysler, Ford, or GM avoided a single management fad?
Have their collective managements through the years embraced of any single fad that led to sustainable improvements anywhere?
Now, it is true that many fads – and we are using that word pejoratively – contain useful recommendations and are consistent with effective and efficient management. However, that’s only if such policies and techniques are thoughtfully applied to one’s particularly organization and situation, and that is a big, bold IF.
Spending vast amounts of time and energy trying to get apply the inapplicable might be hard and expensive work and might require creativity and ingenuity, but it is almost always worthless, regardless of the satisfaction felt by completing a difficult project.
It’s our view that the thoughtful application of sound business policies and practices precludes the necessity for such fads in the first place. A different perspective and specialized expertise are benefits that some consultants offer, but the wholesale revamping of only certain functions is usually myopic and often as senseless as fitting square pegs in round holes. The fact that XYZ worked for firm RST in industry LMN means very little for firm ABC in industry DEF unless there are direct analogues.
Likewise, that fact that RST’s market value increased when it implemented XYZ means very little for firm ABC. For example, one could ask: how were equity markets and industry indices moving in general during that the time of the implementation? As we have all read many, many times, correlation is not causation, and correlation based upon a sample of one generally doesn’t mean much, either.
In every functional area – production, finance, sales, human resources – from quality circles and total quality management to supply-chain management and just-in-time inventories to process engineering – even robotics – to activity-based costing to EVA™ to knowledge management et cetera, et cetera, did the car-makers avoid or ignore a single one of them? (We’ve actually forgotten many older fads or the list could have been longer. We think that quality circles were after disco, but our memory fails.)
Were any faddish techniques thoughtfully applied? Was the wheat, so-to-speak, ever separated from the marketing chaff? Did the success of the implementation (of a previous fad) preclude the adoption of a new one? Were any of the programs true management innovations?
We wonder how much have the “Big Three” spent on large consulting firms that were marketing such fads and implementations during those thirty-five years? To what benefit, and who measured the benefit? The consulting company?
Was the downfall of the big three inevitable? We don’t think so.
Was the time to collapse lengthened or hastened by the purchase of those fads? Could anything have been substituted for in place of those fads that could have provided longer, more persistent benefits? Say, something like thoughtful, disciplined management with a solid understanding of the business of designing, manufacturing, and selling automobiles?
We doubt that one person could possess all of the requisite knowledge to master and directly control all operations and functions of a large auto manufacturer, but that’s not the point. If senior management does not have the personal knowledge to design, build, and sell cars, then it needs the managerial knowledge and discipline to organize and control activities of those who do. That’s not to be outsourced through a sequence of fads.
Without managerial knowledge and discipline, what hope – other than good fortune – does a firm, its employees, and its shareholders have to (1) avoid wasteful fads and other missteps in the short-term or (2) survive in the long-term? This certainly seems to be true for firms with 60% market share in the late 1960s, and 50% market share in 1980, and 35% as recently as fifteen years, ago, and about 20% today. (Of course, we’re speaking of GM, the big three still had nearly 60% of the domestic market as recently as 2003.)
What hope does a government bailout offer for institutions that have squandered so much?
Does anyone else imagine that Henry Ford is spinning in his grave?
