Foreclosure, Subprime Mortgage Lending, and the Mortgage Electronic Registration System

...Mortgage Electronic Registration Systems, Inc., commonly referred to as ``MERS,'' is the recorded owner of over half of the nation's residential mortgages. MERS operates a computer database designed to track servicing and ownership rights of mortgage loans anywhere in the United States. But, it also acts as a proxy for the real parties in interest in county land title records. Most importantly, MERS is also filing foreclosure lawsuits on behalf of financiers against hundreds of thousands of American families. This Article explores the legal and public policy foundations of this odd, but extremely powerful, company that is so attached to America's financial destiny...The article culminates in a discussion of MERS' culpability in fostering the mortgage foreclosure crisis and what the long term effects of privatized land title records will have on our public information infrastructure. The Article concludes by considers whether the mortgage banking industry, in creating and embracing MERS, has subverted the democratic governance of the nation's real property recording system.

The face of America's decline

...Mark Hurd, until recently CEO of HP. See the face of America's economic decline...from ``The Real Reason for Ousting H.P.'s Chief``, Joe Nocera, New York Times: [according to] Charles House, a former longtime H.P. engineer: The way H.P. made its numbers...was not just cutting any old costs, but by ``chopping R.&D.,'' which had always been sacred at H.P. The research and development budget used to be 9% of revenue, Mr. House told me; now it was closer to 2%. ``In the personal computer group, it is 0.7%''...Here we see America's formula for decline... 1. Fantastic pay for leaders 2. Stagnant pay for employees 3. Cutting jobs (efficiencies, forcing harder work, moving off-shore) 4. Slash investments in the future (capex, training, R&D)...

Why founding a three-person startup with zero revenue is better than working for Goldman Sachs. | AdGrok

I joined Goldman Sachs in 2005, after five flailing years in a physics Ph.D. program at Berkeley...I was a pricing quant on the Goldman Sachs corporate credit trading desk...Giving sophisticated models and fast computers to traders is like giving handguns and tequila to teenage boys. Only complete mayhem can result (and as we saw recently, complete mayhem did result)....The quants were there to make sure the guns were loaded, but also to make sure the traders didn't shoot themselves in the foot...

"Banging" the U.S. Stock Market

Chicago residents grew up to the sound of local early morning radio rundowns of pork belly futures and other exchange traded commodities. Every trick in the book from manipulation of soybeans to silver has played out in Chicago's trading pits. Every market professional I've talked to in Chicago since Thursday is of the same opinion. It makes no difference whether human beings or computers are front running and manipulating trades. The gyrations in the market last week have the look and feel of classic market manipulation...

Themis' Take: May 6, 2010 -- The Day That Will Change Market Structure

...The story is not a key-punch error. The story is a failed market structure. The market failed today. The market melted down and ``liquidity providers'' quickly pulled all bids. According to today's Wall Street Journal, high frequency firm, Tradebot, closed down its computer systems completely, as did New Jersey's own Tradeworx,...To make matters worse, while some high frequency firms shut down yesterday and pulled their bids, as we warned they would do for over a year and a half, other high frequency firms turned from being liquidity providers to liquidity demanders, as they turned around and indiscriminately hit bids...The market action of May 6th has demonstrated that our equity market has major systemic risks built into it...The price discovery process ceased to exist. High frequency firms have always insisted that their mini-scalping activities stabilized markets and provided liquidity, and on May 6th they just shut down. They pulled the plug, as we always said they would, and they even admit it in the papers this morning...This is not an isolated incident, and it will happen again.

Web of Debt - COMPUTERIZED FRONT RUNNING: ANOTHER GOLDMAN-DOMINATED FRAUD

While the SEC is busy investigating Goldman Sachs, it might want to look into another Goldman-dominated fraud: computerized front running using high-frequency trading programs...Wall Street commentator Max Keiser...claims to have invented one of the most widely used programs for doing the rigging. Not that that's what he meant to invent. His patented program was designed to take the manipulation out of markets. It would do this by matching buyers with sellers automatically, eliminating ``front running'' -- brokers buying or selling ahead of large orders coming in from their clients. The computer program was intended to remove the conflict of interest that exists when brokers who match buyers with sellers are also selling from their own accounts. But the program fell into the wrong hands and became the prototype for automated trading programs that actually facilitate front running...Keiser and HSX co-founder Michael Burns applied for a patent for a ``computer-implemented securities trading system with a virtual specialist function'' in 1996, and U.S. patent no. 5960176 was awarded in 1999...The listing for Keiser's patent shows that it has been referenced by 132 others involving automated program trading or HFT...

Pricing a CDO - Not only Bad Math, Bad Computation too

A working paper, Computational complexity and informational asymmetry in financial products, Sanjeev Arora, Boaz Barak, Markus Brunnermeier, Rong Ge. sheds some light on the complex mathematical models upon which credit default obligations and other derivatives are based. What Arora et al. prove is not only are many derivative mathematical models impossible to compute, never mind in real time, because they require more computing power than the world possesses, the missing information to run a mathematical model is a very good place to cheat with.

Guest Post: Princeton Economist and Computer Scientists Show that Derivatives Are Inherently Vulnerable to Fraud

...the main default risk model for credit default swaps -- the ``Gaussian copula function'' -- was inherently flawed. Now, Princeton University economists and computer scientists have demonstrated that financial derivatives are also inherently vulnerable to fraudulent pricing. PhysOrg summarizes Princeton's findings: ...sellers of these investments could purposefully include pieces of bad risk that no buyer could detect even with the most powerful computers... the problem arises from asymmetric information between buyers and sellers, and goes against conventional wisdom in economic theory, which holds that derivatives reduce the negative effects of such unequal information.

Not with a Bang but a Whimper -- The Risk from High Frequency and Algorithmic Trading

``There is a general view that one way or another the end result of all the high frequency and algorithmic trading will be a blowup. But I don't think the risk is as big as many are making it out to be...the risk of a cataclysm is constrained by the lack of feedback and lack of tight coupling...As the field gets increasingly crowded, market impact will rise and opportunities will diminish'' First, let me point out the difference between high frequency trading and algorithmic trading. Both execute using computers, and since computers work really fast, both can be accused of whatever sins are embodied in millisecond trading. High frequency trading is a type of proprietary trading. The trader (or his computer) sees a profit opportunity and trades accordingly. This profit opportunity...
