Rajan and his book Fault Lines

Fault Lines by Prof. Rajan is one of an ever increasing number of books recounting the financial collapse of the past few years. Unlike many of the others, Prof Rajan is both knowledgeable and experienced having been at the IMF in a senior role during a portion of this period. Thus this book is written from the perspective of a highly credible professional as well as a hands on operative.

Overall it is well written and avoids the finger pointing polemics that we are forced to endure from the journalist types who have their points to make. Rajan writes in a clear and well structured manner and details the problems, as well as recommending solutions. As the title says the system has certain enduring fault lines that need to be avoided rather than rebuilding upon.

Chapter 1 is the introduction and he lays out the history well. Especially he has a balanced position on who should take the blame and on p. 42 he calls the Government and its actions as the "elephant in the room". He does not take the Progressive's stance and blame the lack of regulation as the sole cause and he does not take the Conservative cause agreeing that all regulation is an anathema. Like any complex system which we will never really understand there must be circuit breakers, and that means some form of balanced regulation. Rajan states on p 43 at the end of Chapter 1:

"Growing income inequality in the United States stemming from unequal access to quality education led to political pressure for more housing credit. This pressure created a serious fault line that distorted lending in the financial sector."

I would strongly disagree with this statement. The US has one of the most open educations systems in the world and despite the less than stellar grammar and secondary systems the university systems are without equal. The problem here was demanding that credit be given to anyone on the part of the Government. Frankly when the Government opens the faucet to individuals who have no idea what responsible lending even means it is in and of itself a recipe for a disaster.

Chapter 2 discusses the whole issue of exports and Rajan's personal recollections regarding the controlled economy of India are telling. India was and to some degree is still a socialist centrally controlled state. It is a window to what can go wrong in an economy centrally controlled. On p 50 he states: "The great Austrian economist Joseph Schumpeter argued that capitalism grew through innovation, with newcomers bringing creative new processes and techniques that destroyed the business of old incumbents." This is creative destruction. The Progressive movement of the early part of the 20th century rebelled against the railroad tycoons but understanding Schumpeter one could have just as easily said, "this too shall pass". Namely in a Hegelian sense each action has a reaction and a resolution. Rajan on pp 54-55 discusses the sometimes success of the old Soviet system. As I was wont to tell my Russian employees that I was trained in the Joe Stalin school of management, never fail, the results would be tragic!

Chapter 4 discusses the US and its "weak safety net" which is a double edged sword. We in the US have limited unemployment benefits. It is in many ways Darwinian in that it is also a force to drive people back to work or seek other alternatives. In Germany, where I ran one of my companies, you cannot fire anyone. It is impossible. That frankly is a barrier to entry for an entrepreneur. Only the large incumbents can work in such an environment. Rajan seems to vacillate between the benefits of the US approach and the need for more social benefits. He discusses the discretionary stimulus approach of the US where the Government chooses who to pay and who not to pay. These he alludes may be seen as political payoffs and may not in any substantial manner truly stimulate.

Chapter 7 is quite interesting. He opens the chapter, pp 124-125, with a simple explanation of the reasons for the collapse of the derivatives. Let me paraphrase:

Consider a company which buys a pool of ten mortgages, all most likely subprime. Now the chance of any one going under is 10%. That means on average only one of the 10 will not pay back. This does beg the question of what factual basis was used to determine this but alas that was left to Wall Street and the rating agencies. Now we create two tranches, bundles, one which get a great interest rate but bears the losses, and second which gets a lower but still good interest rate and has its losses hedged by the first tranche. This works well except that the model is wrong!

What really happens is a Markov chain where when the first guy goes bankrupt, then the probability of another going is not the same but higher, and when a second goes bust it goes even higher. This means that instead of the first tranche bearing all the risk, the risk is moved to the second tranche which never thought it would have any! And then an AIG insures the second, and we know that there is a high probability of at least a 50% loss, a number AIG would never have imagined. Dumb quants! Yes, and on pp 142-143 Rajan details the Trillin conjecture that the changes in Wall Street over the past 30 years resulted in the dumbest guys moving upward relative to the Merlin's mixing their brews in the quant rooms. Rajan rejects that conjecture somewhat but there is considerable truth in it...just look at some of the folks who left and ended up in Government.

Chapter 8 discussing the reforming of the financial world. On p 164 he details a suggestion which should be adopted, the altering of compensation to reflect the risk over time. In Chapter 9 he returns to how to improve things in the US and on p 189 he speaks of the major problem in secondary education, the lack of competent instructors. To teach in a public school you need an education degree. Even if you had a PhD, held faculty position in a half a dozen universities and taught for over twenty years you still needed to learn how to operate an overhead projector and prepare a lesson plan. Thus the lack of educational advantage he posits in Chapter 1 is in many ways a result of the teachers unions barriers to entry of competent folks. Yet he never takes that leap. On pp 192-193 he posits the expansions of unemployment and benefits. Here I would disagree. Just look at the results in Germany, Greece, and other countries. In Russia I could fire a bad employee in Greece he was there until the return of Homer!

Rajan overall does a superb job at presenting the problems, the continuing faults and discussing solutions and safeguards. He deals with facts and logic and he does not tell stories as is typical of the wandering journalist. This is worth a read and for some worth a detailed study.
