The relationship between the doctor and the patient is extremely asymmetric. It is to do with the number of counterparties, and with the diversification. If you take a “medical case”, it represents only a small proportion of the doctor’s total responsibility – it is likely that at any given point of time he is seeing about a hundred patients, and each case takes only a small part of his mind space. On the other hand, the same case represents 100% for the patient, and his/her family. So say 1% on one side and 100% on the other, and you know where the problem is.

The medical profession works on averages. They usually give a treatment with “95% confidence”. I don’t know how they come up with such confidence limits, and whether they explicitly state it out, but it is a fact that no disease has a 100% sure shot cure. From the doctor’s point of view, if he is administering a 95% confidence treatment, he will be happy as long as his success rate is over that. The people for whom the treatment was unsuccessful are just “statistics”. After all, given the large number of patients a doctor sees, there is nothing better he can do.

The problem on the patient’s side is that it’s like Schrodinger’s measurement. Once a case has been handled, from the patient’s perspective it collapses to either 1 or 0. There is no concept of probabilistic success in his case. The process has either succeeded or it has failed. If it is the latter, it is simply due to his own bad luck. Of ending up on the wrong side of the doctor’s coin. On the other hand, given the laws of aggregation and large numbers, doctors can come up with a “success rate” (ok now I don’t kn0w why this suddenly reminds me of CDOs (collateralized debt obligations)).

There is a fair bit of randomness in the medical profession. Every visit to the doctor, every process, every course of treatment is like a toin coss. Probabilities vary from one process to another but nothing is risk-free. Some people might define high-confidence procedures as “risk-free” but they are essentially making the same mistakes as the people in investment banks who relied too much on VaR (value at risk). And when things go wrong, the doctor is the easiest to blame.

It is unfortunate that a number of coins have fallen wrong side up when I’ve tossed them. The consequences of this have been huge, and it is chilling to try and understand what a few toin cosses can do to you. The non-linearity of the whole situation is overwhelming, and depressing. But then this random aspect of the medical profession won’t go away too easily, and all you can hope for when someone close to you goes to the doctor is that the coin falls the right way.

I was thinking of this kind of arrangement as a financial product. Actually, the movie has what I call as the “European version”. More complicated is the “American version” which I describe here. Basically I give you the OPTION to marry me on any day before my 28th birthday (6th Dec 2010). That would be simple enough to “price” (or “value”, to put it in layman’s terms) – it is a standard American option. However, let me add this twist into it. I also reserve the right to withdraw this option on any day before expiry or exercise.

So basically some day before my 28th birthday I can wake up and cancel this option that I’ve given you. Now the challenge is to price this. One thing that is obvious is that the value of this is now less than the value of the pure American option. But pricing it is a challenge (though, thinking about it carefully, it shouldn’t be too hard to solve. I think we can use option-on-option fundaes in order to price it, but still it’s nontrvial).

The European option, of course (as it is done in My Best Friend’s Wedding) easier to price. Basically, there are two events that need to happen on the day of expiry for the option (ok technically it isn’t an option since if these two events happen, then the parties are forced to execute the contract) and so it can be easily modeled using a two-factor model. The American, as we discussed, is tougher (though I’m sure that if I were to present this problem to my colleagues, they’d solve it in a jiffy).

So the reason I’m writing this is that I’m planning to enter this kind of a deal with someone. And I’m wondering if it’s better to enter into a European deal or into an American. Remember that if it is the “American” deal, I’ll be giving away the option (to marry me before either my 28th birthday or I withdraw the option) for free. Considering this, under what conditions should I try to sign the European contract, and under what conditions should I give away the American?

Also, how does the pricing of the American option change if I’m allowed to give it away to more than one person (with the understanding that as soon as one person exercises the option, I withdraw the option from all the other people I’ve given it to). And typically, will I be able to get more benefit in total by giving away this American option to a number of people than if I give it away to one person (assuming I’m indiffernet between all these people with respect to marriage).

Ok it’s late in the night and it’ s my third post in the last 1 hour, so it might be a bit muddled up. Also, you might find it a bit too technical (remember that I’m a quant). Nevertheless, I hope I’ve been able to communicate what I wanted to communicate. And am looking forward to your advice on this.

I borrowed The Black Swan from Aadisht sometime in late 2007. I tried starting to read it several times but never got past Taleb’s childhood stories of his hometown Amioun. I took a couple of months to get past the first 50 pages, I think. And then it was easy reading. I loved the sub-plots. I broadly bought into the main plot. By the time I had finished reading the book, I wanted to ask Taleb to accept me as his sisya. I  bought and read Fooled By Randomness, and liked that too. And then decided to read The Black Swan yet again. It was only a couple of months back that I finally returned the latter book to Aadisht (in the meantime he had bought two other copies of it, and read it).

Till very recently, I would read up any article of Taleb’s that I could find. I wrote to him a couple of times with my CP, and he even responded. I infact wrote to him about “Positive Black Swans and the World of Romance” and he responded with a “Thanks Karthik, Ciao, Nassim”. I had become a worshipper.

However, now I think he’s kinda lost it. I don’t think he intends to write another book and so he has nicely settled down to peddling his last theory (black swan). In response to a recent post on studs and fighters, Kunal had said, “He that is good with a hammer tends to think everything is a nail.”. The same disease affects Taleb I think, as he goes around the world trying to force-fit his black swan model to every conceivable problem.

And then I have a problem with people like Taleb and Satyajit Das, and actually with all those ibankers who are asking for bailouts. These guys made full use of capitalism, and made heaps of money, when things were good. And now that their money has been made, they call for government intervention, and socialism. Taleb and Das are different from the other wall streeters because they are calling for full-scale government intervention, unless the other bankers who are only calling for a bailout!

Now that the elaborate intro is done, let us get to the point. Taleb’s essay consists of ten points. The headings are italicized and there’s a detailed explanation. For purpose of brevity I’m putting only the headings here, and writing my comments after each of them. Go to the FT site to read the full points that Taleb has written.

1. What is fragile should break early while it is still small.

I agree with this. And my take is that competitors need to keep each other in check. For example, if this round of bailouts were not to happen and the biggies were let to fall, no one would grow so big in the future, and even if they did, they would make sure that they were insulated enough from one another. This round of bailouts will make the next crisis (whenever it will happen) worse.

2. No socialisation of losses and privatisation of gains.

Agree with this.

3. People who were driving a school bus blindfolded (and crashed it) should never be given a new bus.

Taleb has clearly not learnt his own lessons (fooled by randomness). I might have crashed the school bus once, but it may not be my mistake. the one data point of one bus crash should not be used to decide my career as a driver. One should look at how the driver drove before the crash to determine whether he gets a second chance. Blanket banning of people involved will not help.

4. Do not let someone making an “incentive” bonus manage a nuclear plant – or your financial risks.

It’s all about structuring. Taleb was a trader and he forgets about structuring. As long as incentives of the employee and the employer are reasonably well aligned, there is no problem with an incentive bonus. The problem in ibanking was that too much emphasis was placed on short-term performance of employees. It’s tragic that the fall of the financial system has brought to an end what was an excellent compensation system (in principle, mind you; not the way it was practised) – where each person was paid fairly based on his/her contribution.

5. Counter-balance complexity with simplicity.

I think the simplest way would be to leave things to the market. Government intervention would lead to a new form of complexity, and in the overall scheme of things increase complexity rather than decrease it. None of the stuff that Taleb has mentioned is easily implementable.

6. Do not give children sticks of dynamite, even if they come with a warning .

Again Taleb prescribes mai-baap sarkaar. Does he realize that if governments had always had tight control over the markets, the markets wouldn’t have crashed on October 19 1987, and he wouldn’t have made any money? (Taleb has reportedly made 97% of his life’s earnings out of this one event). What is “complex derivatives”? And how can you ban it? If you ban it, it’ll go to the black market. You are better off collecting hefty security transaction tax.

7. Only Ponzi schemes should depend on confidence. Governments should never need to “restore confidence”.

I agree

8. Do not give an addict more drugs if he has withdrawal pains.

Agree once again. We need to structurally change things to get to saner leverage than what was practised 1-2 years back. Regulations should be simple and principles-based, minimizing chance for regulatory arbitrage. Remember that the purpose of creation of most “complex derivatives” in the last 25 years is regulatory arbitrage.

9. Citizens should not depend on financial assets or fallible “expert” advice for their retirement.

Bullshit. The point on markets not containing information, that is.

10. Make an omelette with the broken eggs.

None of this makes any kind of practical sense. It’s just an old man ranting. Thanks, guru (pun intended).

• On Saturday, I spoke to this guy who is a banker in the City of London. He says that one major fallout of the global economic crisis is that the financial markets have become highly inefficient.
• Knowing that they won’t get bonuses, he says, bankers have no incentive to arbitrage these inefficiencies. Sadly, people refuse to believe that investment bankers perform socially useful and productive work

• Yesterday, I was talking to this guy who runs a manufacturing SME. He says that apart from one really bad month (January) when orders fell over 50%, he is doing quite well.
• Thanks to the downturn, a few manufacturing shops have shut down in various places in Europe. Now, the erstwhile customers of these erstwhile manufacturing shops are looking towards India for their sourcing. My friend is hopeful of bagging one such contract.
• Thanks to the downturn, firms are integrating their manufacturing. For example, a prominent stationery manufacturer has decided to manufacture 100% of its products from its plants in India. My friend has been a long-term supplier to the india plant of this particular manufacturer, and now expects to get more business from them.

Interesting stuff overall.

Her second sister, along with her husband, has been appointed the lead investment banker for this deal. My mother’s eldest sister is going to be the chief scout in order to scout for possible counterparties to the deal. It is preferred, and desirable, that there be a single buyer for this entire 50%, and the current understanding is that if we are not able to tie up any good single investor, we will rather postpone the sale rather than going in for an IPO and selling the stake in bits and pieces to retail investors.

Thinking about it, I wonder if it is technically correct to call this a stake sale, since I don’t plan to take any dowry. Maybe if you take all costs into consideration, and not just the monetary ones, and if you assume payment to be a continuous thing rather than like a lumpsum (these  investment bankers, they can arrange just about anything), it won’t be inaccurate to call this process a stake sale.

Usually, in these circumstances, most of the work is done by the bankers, but it seems that in this case that I, as the person divesting the stake, will need to put in considerable effort. The effort that I was too lazy to put when I was supposed to be trying to do the deal myself, without any asssistance from any bankers. Actually this is something that a lot of companies that indulge in M&A transactions forget about.

Think about your own incentives and the banker’s incentive. For the banker, this is just a deal. All they are caring for is to find a buyer for your sale, and a seller for anyone who wishes to buy stake. Once the deal is through and the cheques and documents signed, they ask you to sign on a set of fairly heavy cheques, and walk away; job done. It is you, as the company who is selling the stake, who has to deal with the new investor for maybe the rest of your life – transaction costs in these kind of deals are high, and it is preferable it be done exactly once.

One thing I realize is that the effort required here is of a different nature to the one that you need to put when in the market without bankers’ support. In the latter case, you need to engage in an elaborate ritual of tiki-taka, slowly moving towards the goal, and then unleashing a shot at the right moment. It is a well-respected and common algorithm, and any attempts to side-step it, and use short-cuts, usually end in disasters.

In the banked world, though, one thing is clear – you are sitting in that conference room together in order to strike a long-term deal, and not for a random networking meeting. All parties in the conference room are aware that the reason they are all sitting there, together, is so that they can work out a long-term deal. And thus, explicitly mentioning the deal, and explicitly working towards it, are not frowned upon – like it sometimes is in the outside market. You don’t need an y tiki-taka here. Tiki-taka is also seen as a waste of time. You better follow a direct approach and just put the ball in the box and then have a striker shoot it.

And remember that in such brokered deals, there is usually no goalkeeper.

PS: I need photos of myself for the offer document. I realize that I dont’ have too many of those. I’m not too narcissistic in my photography exploits, and I dont’ bother to collect pics that others have taken of me, and hence the shortage. Last night, my mother looked through my facebook pictures and pronounced each of them as “useless”. So, if you have good pictures of me, plis to be sending me. If you dont know my email ID, just leave a comment here and I’ll give you my email ID.

It was also a period of extreme NED, due to which i didn’t bother looking out actively to try consult for an IPL franchise. It was a period of low confidence, so I assumed I wasn’t good enough for this kind of work, and didnt’ bother doing anything in this direction. Frankly, I didn’t have a clue how to proceed, else i might have put SOME effort at least. A few months later, when the IPL was well underway, I figured out that one of my cousins is a big shot with Bangalore Royal Challengers, and he was among the people at the Trident who picked the Test XI to represent BRC. I wanted to kick myself, but for some reason I didn’t.

Currently, I’m comfortably employed, and so far have been happy with this job. Else I might have wanted to throw my hat into the ring. Once again, IPL team formation season is on. A few transfers have gone through already, and a few are currently in limbo. Bidding will happen next season for people who are joining the league this year. It promises to be an interesting time. And so far I’ve been deeply unhappy with the way the franchises are going about their business.

I’m especially upset with BRC, and have half a mind to call up my cousin who consults for them and give him a piece of my mind. How the hell could they let go of Zaheer Khan in exchage for Robin Uthappa? Yes, the latter is from Bangalore, and has that local pull factor. He has batted quite well this Ranji, though not anywhere close to what he played like 2 seasons back when he topped the batting charts. But he is supposed to be paid twice of what Zaheer was being paid! Is he really worth that much? I’m sure that BRC missed a trick here. I’m sure that had the BRC asked for a fee from Mumbai Indians in order to release Zaheer in exchange for Uthappa, the Indians would’ve definitely paid up. When Chelski can reportedly offer Anelka, Malouda, Alex and 15 million pounds in exchange for Robinho, Mumbai could definitely part with Uthappa and maybe a million dollars in exchange for Zaheer.

There were rumours of the Mumbai Indians negotiating a swap with Kings XI Punjab for a swap between Powar and Harbhajan, which reportedly got stalled because Harbhajan earns so much more than Powar. Once again, what if the Mumbai Indians paid a fee along with Harbhajan for Powar? I know it is ridiculous that Powar is worth Harbhajan plus a fee, but given their disparity in income, this is the only way that this deal is possible. And I’m sure that there is a particular fee, which if paid along with Harbhajan in exchange for Powar, will leave all the interested parties (Punjab, Mumbai, Harbhajan, Powar) better off. It seems like people are too lazy to find it.

The opportunities like this are endless. All that the franchises need is someone who has sufficient knowledge of game theory, coase theorem, a decent knowledge of cricket (interest in domestic cricket is a desirable quality) and who understands how to structure deals. I don’t know if franchises have already recruited such people but if they haven’t, they should try and recruit. The most obvious choice of person that I can think of who possesses all the above skills (including interest in domestic cricket) is me. Unlike last year, I’m not in the job market right now, but don’t mind doing some part-time stuff. I may not get paid, but I’m willing to work for a few IPL tickets and maybe invites to some parties with cricketers.

I’m also wondering if cricketers’ pay will go down starting the 2011 season onwards. The IPL auctions happened just before the downturn was to begin, and I’m sure that franchises have overpaid for most players. Since players have all signed three year contracts, their pay till the 2010 season is safe. Beyond that, I’m not sure if franchises will offer them fresh contracts at higher or equal salaries.

It would also be interesting to see if some version of the Bosman ruling is to operate in the IPL. We can only wait and see.

One of the major problems of the financial crisis that has been happening for about two years now is that investment bankers, as a profession, stand discredited. Before this, they used to claim to be on the top of the intellectual ladder. And now, thanks to a handful (more than a handful; but still a small proportion) of phenomenally stupid investment bankers, the entire community stands discredited. Not just that, they have left the community of quants, of people who can be good at structuring, of finance people, of statisticians, all discredited. You say “all you need to do is to get a few ibankers into these jobs” and you’ll have people come at you like a pack of hounds, waving Mint and saying “look at the damage these buggers have caused, and you think they can solve this problem”.

So Baada and I were talking about cricket the other day. About how thanks to the demands of television, flat pitches are being prepared everywhere. Which is leading to tame and boring draws. Which has led to domestic cricket being effectively reduced to a one-innings game. Which has led to massive fourth innings run chases. Which has led to bowlers break down once every couple of seasons. And so forth.

The argument put forth in favour of flat pitches is that in order to maximise television revenues, you need the game to last five days. Excellent argument, and Baada and I agreed to it. But the friggin’ point is that if you have  a boring game, no one is going to watch it. If you have a game that is most likely to end up as a draw, it will have no audience. Advertisers would be paying through their nose for near-zilch viewership.

In the medium term, things should even out. Advertisers will realize that due to the boring nature of Test cricket, no one will watch it anyway, and will back away. Ad rates will fall. And TV rights bids will fall consequently. And the boards will understand their folly and take steps to make cricket interetsing again. (there is also the danger that boards will use this to say that no one watches Test cricket anymore and scraps it altogether). However, advertisers should not be so passive and wait for things to even out.

Given a large number of statistics, playing conditions, day of week seasonality and all such stuff, it shouldn’t be hard for the smart advertiser to figure out which are going to be his most profitable slots. And bid specifically for those. If one smart advertiser does that, then that advertiser stands to gain against other advertisers who will end up paying more money for less profitable slots. And so all advertisers will become smart. Now, the channels will stop seeing uniform demand patterns for their various advertising slots. They will now need to acquire smartness in order to combat the smart advertisers. This way, smartness will prevail in the system.

I’m sure that once something like this happens, natural balance will get restored. It will take much less time for TV channels to realize that three-day Tests on bowling pitches can get them greater revenues compared to runfests played over five days. And they won’t take much time to communicate the same to the boards who will then restore Test cricket back to glory.

The problem with a lot of advertising people is that they see themselves as “creative people” because of which they assume they don’t need to know and use maths. And they don’t do the smart calculations I described earlier. As for the brand managers, it is likely that a lot of them decided to pursue marketing because they either didn’t like quant or found themselves weak at quant. Apart from a few simple excel models, they too are likely to shun the kind of smartness required here.

So where are the white knights who can save the version of the gentleman’s game played in whites? Not currently in the ad agencies. Most likely not in the marketing departments. They are all out there. A few months ago, they were employed. Earning very good salaries, and grand bonuses. Earning amounts of money unaffordable to most advertising and marketing companies. Thanks to the financial meltdown, they are available now. Looking for a fresh challenge.

This is the best time for you to infuse quant to your business. You won’t get the kind of quant supply in the market that you are seeing now. Even if the financial industry doesn’t recover (in any case it will never go back to 2007 levels), supply side factors should ensure lower supply. Do that little experiment now. Acknowledge that numbers can do a lot of good for your business. Understand what structuring is all about, and estimate the kind of impact a good structurer can have on your revenues. Make that little bit effort and I’m sure you’ll get convinced. Go make that offer. An offer these ex-ibankers can’t refuse in the current circumstances at least.

PS: When I refer to investment banking, I also include the “outside-the-wall” side of the business (called “markets”; “sales and trading”; “securities” and various other names). In fact, I mostly talk about the outside-the-wall business, not having had any exposure inside the wall.

That was the year when I had started preparing for the JEE. I had joined BASE, the best JEE factory in Bangalore. I was having a hard time since I hadn’t studied one bit in all of 11th standard when my friends had dilgently solved Irodov and other books. I had missed one whole month of prime summer holiday JEE prep thanks to the Math Olympiad Training Camp. I knew I needed to be focused. I knew I didn’t want to be distracted. However, I also knew that I would be under tremendous pressure for a year, and any means of easing a bit would be welcome.

During our monthly counselling sessions at BASE, the Director would call for us to create angst. “You need to have the fire in the belly”, he used to say. “And be able to channel it in the right direction in order to fuel your effort. Without fire in the belly, nothing can be done”

I must mention here that this was one of those unintended consequences things. I didn’t plan out this delta hedge. I realized the hedge only in hindsight. I had just followed my instinct in doing what I eventually did. Looking back 9 years down the line, I think it was a fair idea. Only, that like in everything else that I do, the implementation was horrible. Nevertheless, I think the learnings from this are going to be useful, and are going to have a net positive impact on society.

I put blade like naayi on a classmate, who is perhaps the most brilliant woman I’ve ever known. She was a good friend back then, at the point of time when I started the blading process. As you might have come to expect of me, I did a pretty horrible job. Disaster would be an understatement. It was depressing. I lost many nights of sleep to this. If I were less informed, I would’ve classified it as a blunder.

If you noticed, I had slipped in a little para where I mentioned the need for creating fire in the belly. This failed blade would fire it. This failed blading attempt would provide the angst, which I could channel in the right direction if I so wished. This failed blading attempt would make me angry, would make me upset, and would help me focus on my goals. And the sleepless nights this failed blading attempt gave me – I used them for mugging for the JEE.

I don’t know if I’ve told this particular bladee about it (I probably have), but I’ve always internally dedicated my success in the JEE to her.

However, this story was not to end happily. The delta was hedged, but the gamma would come back to bite me at a later date. The angst and the anger and the pain was fine when I needed them, but now (after I joined IIT) that I didn’t, it led to NED. Terrible NED. This would go on to be one of the biggest causes of NED during my life at IIT. As Shah Rukh Khan says in Baazigar, “kuch khaane ke liye kuch pona bhi paDta hai”.

There is no point in my narrating the Ramayana for a year and then you saying that you thought I was narrating the Mahabharata.

To compensate for not putting the full letter as promised, I am putting here Rahul RG’s excellent commentary on the issue. RG was 3 years my junior at NPS Indiranagar, IIT Madras and IIM Bangalore. It’s in the form of a GTalk conversation. It’s slightly longish so I’ll put it under the fold.

me: if you think the scope of finance and derivatives is getting limited, then you should read my latest blog post

me:

too much da

Rahul: yes, i saw that
