Bay Bridge Opening? (Updated twice)

Like we haven’t heard that before. But yet, the Bay Bridge Blog reports:

511.org: “The bridge is expected to open sometime this morning.”

SF Chron: “Things have gone very well overnight,” Caltrans spokesman Bart Ney told reporters at a briefing early today. “We completed a lot of the work that we needed to do. It does look like now that we’re going to get the bride open today.” [link]

Update: Also posted @BayBridgeInfo (the official site) on Twitter (direct link to tweet).

Second update: The Bay Bridge is open! [link]

Choose the Side You Start With

A study finds that coin-tossing is actually not so random:

We analyze the natural process of flipping a coin which is caught in the hand. We prove that vigorously-flipped coins are biased to come up the same way they started. The amount of bias depends on a single parameter, the angle between the normal to the coin and the angular momentum vector. Measurements of this parameter based on high-speed photography are reported. For natural flips, the chance of coming up as started is about .51. [link]

We’re Number Two! We’re Number Two!

The World Economic Forum (WEF) released its annual rankings of global economic competitiveness last month, and it turns out that the USA is no longer the most competitive global economy.

The World Economic Forum today released its annual rankings of global economic competitiveness, and Switzerland knocked the United States out of its No. 1 spot. The report blamed the United States’ slippage on “weaker financial markets and less macroeconomic stability.”

Meanwhile, some leading emerging markets like Brazil, India and China improved their competitiveness scores. Zimbabwe and Burundi were once again deemed the world’s least competitive economies. [link]

Collateral You Can Eat

Now this is a prize currency.  From Bloomberg:

The vaults of Credito Emiliano SpA hold the pungent gold prized by gourmands around the world — 17,000 tons of parmesan cheese.

The regional bank accepts parmesan as collateral for loans, helping it to keep financing cheesemakers in northern Italy amid the worst recession since World War II. Emilia Romagna-based Credito Emiliano’s two climate-controlled warehouses hold about 440,000 wheels worth 132 million euros ($187 million).

The bank offers loans for as long as 24 months, equal to the time it takes the parmesan to age, at the euro interbank offered rate, plus 0.75 percent to 2 percent, Bizzarri said. The bank gives producers as much as 80 percent of the value of the product, based on current market prices. [link]

Nice terms, but what if you get hungry at some point between now and loan maturity?

Rational, Irrational or Something Inbetween?

Dan Ariely, a behavioral economist at MIT, talks at TED in 2008. The talk, according to the official bio, is about the following:

Despite our best efforts, bad or inexplicable decisions are as inevitable as death and taxes and the grocery store running out of your favorite flavor of ice cream. They’re also just as predictable. Why, for instance, are we convinced that “sizing up” at our favorite burger joint is a good idea, even when we’re not that hungry? Why are our phone lists cluttered with numbers we never call? Dan Ariely, behavioral economist, has based his career on figuring out the answers to these questions, and in his bestselling book Predictably Irrational (re-released in expanded form in May 2009), he describes many unorthodox and often downright odd experiments used in the quest to answer this question.

Daily Show Shenanigans

Apparently Tim Geithner can’t sell his house, and this brought his house – not him – onto the Daily Show, with Robert Shiller making a cameo.

It starts by describing the thawing real estate market but noting a “tragic tale” about “a family forced to move when the father had to take a job in a different city, and now their well-appointed home remains unsold.” The house, of course, is Mr. Geithner’s. [link]

The Statistics of Disagreeability Within the Econoblogosphere

(via MR)

Leigh Caldwell at Knowing and Making does an ad hoc analysis of the how disagreeable economists really are, by examining words and trends in blog-postings, their titles and their comments from the econoblogosphere. He looks at four different categories:

  1. Articles whose title contains the words “is right”, “agree” or “genius”
  2. Articles whose title contains the words “is wrong”, “disagree” or “idiot”
  3. Articles whose content contains ”is right”, “agree” or “genius”
  4. Articles whose content contains ”is wrong”, “disagree” or “idiot”

And the results?

Surprisingly (at least to me), economics bloggers are more agreeable than not. “Agree” articles (category 3) showed up more than twice as often as “disagree” (category 4). When measured by titles, the trend is not so clear, with a majority “agree” articles (category 1) when measured over the last two months but more “disagree” (category 2) when taking the last 7 days alone. [link]
Economists have to deal with a tough crowd, it seems.
However, blog readers are not so magnanimous. On the content measure, the mean number of comments on an “is right” article (category 3) is 3.66, while there are an average of 6 comments on an “is wrong” article (category 4).
When the title filter is used, the difference is even greater: there are no comments at all on the category 1 (“genius”) articles, and an average of 21.6 on category 2 (“idiot”)! [link]
Caldwell, by the way, was responsible for generating the economics blog word cloud (pic below).

April Fool’s Google-Style

Some of you may have noticed Google’s new feature – Gmail Autopilot(TM):

As more and more everyday communication takes place over email, lots of people have complained about how hard it is to read and respond to every message. This is because they actually read and respond to all their messages. [link]

Amazing. Simply Amazing. Enjoy it while it lasts, it’s probably not going to be around tomorrow.

F-Double-Prime is Finally Greater Than Zero?

In spite of yesterday’s news that the industrial production and capacity utilization took a nosedive, there seems to be a general feeling that things may have bottomed out, and it might be a turning point. In today’s NYT:

An unexpected rise in housing starts and a more moderate increase in wholesale prices offered some brighter economic news on Tuesday as the Federal Reserve’s Open Market Committee met to assess its policy course. [link]

In last month’s Economist:

MANY of the diehard optimists on Wall Street have been beaten to a pulp by now, but those still standing have fallen back on a nifty bit of calculus. The second derivative, they say, is turning positive. That means that although the economy is spiralling down, it is doing so more slowly.

Retail sales rose by 1% in January from December, the first monthly increase since June. Car sales fell in January but were stable to individual buyers, if not to corporate fleets…An index compiled by JPMorgan Chase finds that although economic news remains on balance worse than expected, the margin of awfulness has shrunk a bit; the firm’s analysts have marginally trimmed the risk of “a mini-depression”. …[And] thanks to huge policy stimulus by the authorities since October, yields on corporate bonds have edged lower, interbank rates have improved, and the money supply has surged. [link]

And in yesterday’s WSJ Real-Time Economics:

It is probably still too early to say that the U.S. manufacturing sector is approaching the bottom of this deep recession. However, the rate of decline of non-auto manufacturing output has slowed in the last couple of months—in the jargon of calculus, the second derivative has turned positive. This is a potentially good sign and, if it persists for the next few months, will signal that a trough is at hand. – Nariman Behravesh, IHS Global Insight [link]

Let’s not get too excited, though. Not everyone agrees on this:

“Many are interpreting the February data on starts and permits as signs that a bottom is forming in the housing market,” said Richard F. Moody, chief economist at Forward Capital, in a note to investors. “This is more a case of wishful thinking than a reflection of reality.”

And wholesale prices in the United States edged up a hair in February, but flatter energy prices and the continuing economic downturn kept any price increases to a minimum. [link]

And we still have a long way to go:

“We’re seeing some big declines in things like synthetic fibers, lumber, phosphates, organic chemicals — the things that are used to make these products are decreasing,” Anika Khan, an economist at Wachovia, said. “Further in the pipeline there’s going to be some more easing.”

Analysts said that those weaknesses suggested that deflation would remain a concern — if not a cause for panic — as the economy continues to contract. [link]

Not to mention jobless claims increasing, and other indicators still showing strong signs of a contraction. Still, small positive scraps in a universe of negativitiy are always nice to see.
