Computer Models and the Global Economic Crash 361
Anti-Globalism passes along a review in Ars of some recent speculation on the role of interconnected computer models in the global economic crash. "If Ritholtz, Taleb, Mandelbrot, and the rest of the computer modeling and financial engineering naysayers are correct about the big picture, then we really are arguably in the midst a bona fide computer crash. Not an individual computer crash, of course, but a computer crash in the sense of Sun Microsystems' erstwhile marketing slogan, 'the network is the computer.' That is, we have all of these machines in different sectors of the economy, and we've networked all of them together either directly (via an actual network) or indirectly (by using the collective 'output' of machines in one sector as input for the machines in another sector), and like any other computer system the whole thing hums along nicely... up until the point when it doesn't."

I really think that the government could free up a huge quantity of the credit blockade by lending directly to the enduser to force the various credit companies to wake up and try to compete for their markets.
Example: Home loans. 30 year fixed rates have usually floated at around 2+% over prime. Now because the mortgage companies wrote unserviceable loans so they could sell them instead of service them, they are all licking their wounds and are currently loaning at 5+% over prime. This works out to a subsidy to the mortgage companies so they can make up for their idiot losses. At the same time no one can sell their house because no one can get credit and if the houses don't move the price drops screwing home owners. At the same time banks are dumping foreclosed homes further driving down the home price comps. (Oh and the banks DO make loans for the houses they are dumping!!!)
If they would just refinance the so called "Toxic debt" mortgages at 3% over prime it would drop the payments down to a point where most of the "toxic" loans would be workable for the debtors and then they wouldn't be toxic. At 3% over prime it would be plenty profitable too. If they would force the mortgage companies to carry the paper on a portion of the loans (selected at random) it would guarantee that they wouldn't write fraudulent loans either...

Wrong. The cows do, in fact, produce more milk every year (not the individual cow, but the average cow). More importantly the dairy industry becomes more efficient every year, making it possible to have more cows using fewer resources..
"The greatest shortcoming of the human race is our inability to understand the exponential function." -- Albert Bartlett
Production and efficiency in a single industry can only increase for so long before the results become absurd or impossible.
The average dairy cow in the US produces ~20,000 pounds of milk annually (rounded for simplicity). If we pretend we can get 3% improvements annually, then after 100 years we'll have nineteen times the milk we started with. At the end of 200 years, each cow is producing a pound of milk every four and a quarter seconds. In 300 years, 4.5 pounds/second. You'd have to stick a pipe down its throat just to prevent dehydration.
And as far as more cows using fewer resources goes, you run up against basic physics. Calories in >= calories out. Efficiency improvement is constrained by the universe.

In fact, banks quite literally create money by making these loans, which is how the US money supply grows (and is one of the reasons why adjusting the interest rate affects inflation... if you reduce the rate at which loans are granted, you reduce the rate the money supply grows, which translates to lower inflation).

Also there are a few uncertain assumptions in your little 'analysis' -- one, that the seller chooses to reinvest his sale profits with the bank. You claim that most cash proceeds from the sale of houses was deposited in banks -- this is false. Most was actually reinvested in other real property or elsewhere.
Plus, you ignore the opportunity cost of the funds the bank is due and the risk of default (hence the interest rate on the loan).
I know the banking industry has its problems, but claiming it's a ponzi scheme is just uneducated. The banking system is NOT dependent on influx of new investors to pay their creditors (leaving a gaping cash hole when new investors stop appearing). They are dependent on the stream of payments from existing debtors. When that stream dries up, their ability to lend dries up, since they become cash-flow negative, and eventually have no capital to lend.
The problem is that the banks are unwilling to lend when the expected return on their capital outlay is negative. Due to the fluxed up state of the economy, banks in general have decided that lending is unwise, since the risk of default is so high. The big problem is that banks did not properly assign risk to certain loans, so that they undercharged on the interest rate. The reason this slightly relates to a Ponzi scheme, is that as long as another bank was willing to underwrite a risky loan, then bank could get rid of its risk when the property in question was sold. It was a game of hot potato -- whoever was left holding the risky loan when everyone stopped lending lost. And the big problem was that it continued for too long -- eventually the amount of risky loans was so large that almost *everyone* was left holding a sack of hot potatoes. If credit rules had been tightened, rather than loosened, then a few banks would have gotten burnt early, and the problem would not have spiraled.

Maybe it's a way of getting a loan without going through a bank or issuing stock. Say you want to build a new factory with payroll rather than actually pay your employees; maybe you're assuming the factory will pay off the interest on the corporate paper and then some.
The biggest thing at the end of the Wikipedia article you read is that, whatever the reason the money is needed, it's cheaper than getting it from a bank. If a corporation is big enough and has good enough credit, they can issue corporate paper, at a lower interest rate, instead of paying interest to a bank.

Because once a business gets large enough, the cash flow becomes enormously more complex, and very short term credit becomes a cost-effective way of managing cash flow.
Basically, a business wants to match cash inflows with outflows (and to simplify the model, we'll count "profits" as one of the outflows). The problem is when you know that your business is owed cash that's going to arrive in unpredictable payments over the next 30-90 days. Setting up the cash outflows so that they precisely match the inflows becomes hellishly more complex when the number of transactions gets big enough. Short term debt provides a buffer that allows a business to simplify this.
In principle, yes, a business could do the same thing by keeping cash reserves as a buffer, too. But when you take into account the time value of money, that really comes down to the same thing: by keeping cash, the business implicitly pays the opportunity cost [wikipedia.org] of keeping that cash. (And with an inflationary monetary policy, of course, the cash itself becomes less valuable over time.)
So, to sum up, the money owed to the business over the short terms is its accounts receivable [wikipedia.org]; short-term debt allows a business to convert, for a fee, a large fraction of its accounts receivable into cash, and therefore, to draw upon its accounts receivable to finance its operations. I.e., instead of having n dollars of pure, unencumbered cash at its disposal at any one time, it can have n + ((accounts_receivable * reliable_fraction_of_a_r) - interest_on_short_term_debt)); or, equivalently, to keep less unencumbered cash than it would otherwise need to.

So now I can have a HELOC, personal line of credit, credit card, savings account, etc, all tied together, in that credit from one reduces the amount of credit available on another, and all paid from the same account.
The only reason you "need" all that is because the banks created all these funny rules so that they could introduce more and more products and services.

I think the idea behind those instruments was basically sound, but the things ended up being a lot more complicated than people thought. It makes sense that if you lump a bunch of mortgages together, only a small percentage of those will default, thereby distributing your risk. But in a climate where fraud was rampant and the people signing people up for mortgages had no incentive to make sure people could actually pay those mortgages back, your lump of mortgages has a much higher chance of containing too many bad mortgages to make the resulting instrument profitable.
The derivatives market had the perverse effect of creating and encouraging that climate, because the mortgage buyers would buy without enough questions because they knew there were buyers who would buy the derivatives without too many questions. The fundamental problem with the whole concept, it seems to me, is that the derivative buyers and sellers forgot to insist on and question the credentials of the individual mortgagees they were investing in.

One of the reasons for this "redundancy" is (or used to be) that different rules apply to each kind of account. You used to have have commercial banks, investment banks, and insurance companies, and each did something different under different rules. Then the rules that had been in place since the Great Depression were repealed by Gramm-Leach-Bliley, and suddenly the legal boundaries between these kinds of financial services was gone.
Subsequently, we are facing the greatest economic crisis since the Great Depression. Coincidence? I'm not entirely sure, but surely some of the problem is that practices and attitudes that were normal in investment banking suddenly started to crop up in other businesses.
Although Hank Paulson is actually, in my opinion, one of the more decent individuals as a person in the administration, he's very much the wrong man at the wrong time. One of the things he did as head of Goldman Sachs was to convince the SEC to get rid of the "net capital rule". That was the rule that required banks to maintain a certain level of cash on hand to cover cash demands in unusual situations. This is obviously extremely expensive for companies who had to keep huge volumes of cash on hand, losing mind boggling amounts of value even against modest inflation.
Had the rule been kept in place, we might not have had to pony up seven hundred billion dollars to bail out Wall Street.

That would make sense if it were true. Federal law limits the number of withdrawals from certain accounts to six per month. That's not a bank policy. It's a law. Basically, the government wanted to force banks to keep a certain minimum amount of cash on hand (not loaned out to customers), and to preserve that, they put in place both dollar limits and that cap on transactions. Presumably this was because (at the time) computing the amount of cash on hand at the bank took a significant amount of effort.

Computers and computer modelling makes it easier to create advanced derivatives and such. But it doesn't make us do it. Just look at the engineering world; We don't choose technically advanced solution just because we can. In fact, the tendency is to go for the simplest possible solution. ("KISS rule")
There's only one reason why you would create advanced, incomprehensible derivative structures: To con people, essentially. To obfuscate the risks. To create money out of nothing. (the most profitable way to make it)
That's not a new problem. There's a reason we created financial regulations, why we have book-keeping, demand financial transparency, auditing, etc. This happened because it was allowed to happen. Because nobody stepped in and stopped this obfuscation from happening. I don't blame the computer models. If someone cons you into signing a bogus, misleading contract - the problem isn't with the paper it was written on or the language that was used. The problem is with the law allowing such contracts to have legal force (which is a regulatory problem from another century).
To extend that analogy, this is a bit like standing in that situation and asking whether or not written contracts are a bad thing, and whether we shouldn't go back to simpler, oral contracts. The bottom line is: As long as it's profitable, there will always be people trying to obfuscate and hide information for economic gain, and there will always be a need for regulation and oversight to stop people from doing that. But blaming the methods by which it's done is pointless.

The models, probably because of "free market" ideology, assume a market where Adam Smith's "unseen hand" is at work. The modelers don't consider the kinds of markets described by Charles Mackay. Most of the models are based on the Black-Scholes option pricing theory. If you look at the assumptions underlying that theory, they describe good behavior, efficiency, and changes describable by what amount to small-signal statistics.
