Krishna Subramanian’s List of Things to Read and Learn

Krishna Subramanian, Ajinkya Jadhav’s batchmate in SCMHRD, was kind enough to message me separately on LinkedIn, and send across his list of things students might benefit by reading, along with some tips and tricks that he found to be useful.

If you have finished college and are reading this, a request: please help out students who are currently in college, and are wondering how to add to their learning. I and other faculty members can help out with syllabi and all that, but you are folks with skin in the game. What helped you in your career, what helped you learn better, what did you wish you had done when you were in college?

I’m reachable on LinkedIn and on email. Please send along your recommendations, and I’ll share them here. Thank you!

On to Krishna Subramanian’s list – thanks a ton for sending these in, kind sir 🙂

 

My own top 5 books which all MBA Streams should read
1) Basic Economics by Thomas Sowel
2) Atlas Shrugged by Ayn Rand
3) Intelligent Investor by Benjamin Graham
4) Goal by Etiyahu Go
5) Life and work priciples by Ray Dalio.
6) Linchpin by Seth Godin (Bonus)

Books for Finance professionals, Other than above:
1) Manorama Yearbook
– If you are working in India, it would surprise you how little you know about India. Keeping this handy and going through once in a while is a massive boon.
2) Security Analysis By Graham & Dodd
3) Damodaran on Valuation
4) R programming for dummies. (most underrated skill any finance professional can have)
5) Warren Buffett and the interpretation of financial statements by Mary Buffett and David clark.

This should help.

I would recommend the following technology trends
to keep an eye on:
1) Blockchain ( Blockchain Revolution by Don and Alex Tapscott is a good read )
2) Artifical Intelligence ( course by Andew Ng on Coursera and Prediction machines by Agrawal gans and goldfarb)
3) Augmented Reality (best is youtube videos, because you really need to understand visually why this will change business)

Ajinkya captured the blogs and podcasts perfectly, so I figured I would add a list of don’t dos?

1) Do not read any book only once.
2) Accounting is a mechanical process but Finance is not. Do not be close minded on how things must be done. (once you come into the world, even accounting is not mechanical)
3) Do not forget your basics. NPV, IRR, Time value of Money, P&L, Balance sheet, Cash flow statements.. these things should be absolutely solid. Its remarkable how many people still fumble with these.
4) Do not ignore Taxes./hidden charges. We always do things ” tax exclusive” but remember, taxes/ hidden charges are a massive key to anything. Eg: Read about active and passive Mutual Funds.
5) Do not call Ashish as Sir. (This is correct, and important – Ashish)

Lastly I think Ajinkya captured it best, you are the average of the 5 people you hang out with. Even if you read none of the above, bring out ruthless choice in your company.

Thank you for all the learnings,
Krishna Subramanian

 

Signaling, Bundling And College

What is bundling? It’s selling more than one thing for a single price. When you buy a cup of coffee, you’re buying a cup of coffee.

But when you’re buying a cup of coffee at Starbucks, are you just paying for the coffee, or are you paying also for the air-conditioning, the Wi-Fi, the chairs and the overall ambiance? In fact, for quite a few folks who choose to work out of Starbucks, the coffee might end up being the least important of the things they’re paying for. That’s bundling.

Here’s an MRU video about the topic:

 


 

What’s signaling?

This thought experiment is borrowed from Bryan Caplan, author of the book The Case Against Education:

Take your pick: a world class education while you were/are in college, from the very best in the world in your chosen field. You get to pick your dream educators, your dream college, you get access to absolutely world class faculty, libraries, whatever. The works. But: no degree. You will never be able to show or prove your credentials to anybody. World class learning, but no proof that it took place.

OR

A certificate from whichever college and course you pick in the world. Harvard PhD? Here you go. B.Tech from the IIT of your choice? Check. But: no learning. You will never be able to attend classes and learn in that college. You’ll get the degree, but sans learning.

If you chose the latter option (I would and I do), you know what signaling is.

Here’s Wikipedia:

In contract theory, signalling (or signaling; see spelling differences) is the idea that one party (termed the agent) credibly conveys some information about itself to another party (the principal). Although signalling theory was initially developed by Michael Spence based on observed knowledge gaps between organisations and prospective employees, its intuitive nature led it to be adapted to many other domains, such as Human Resource Management, business, and financial markets.

In Michael Spence’s job-market signaling model, (potential) employees send a signal about their ability level to the employer by acquiring education credentials. The informational value of the credential comes from the fact that the employer believes the credential is positively correlated with having the greater ability and difficulty for low ability employees to obtain. Thus the credential enables the employer to reliably distinguish low ability workers from high ability workers.


 

There’s many variants of the Caplan question that are possible. For example, would you prefer to wear an original Nike T-shirt without the logo, or a fake Nike T-shirt with the logo?

If I may be permitted to veer into slightly dark territory: would you prefer to be in a happy relationship, or show that your relationship is happy?

We are, all of us, signaling all the time. Modern society wouldn’t be possible without signaling, because the cost of communicating in a world without signaling would be too high.

But education? It doth signal too much, methinks.


 

Let’s go back to bundling, and think about education. What are you buying when you enroll in a college?

If you are an optimistic sort of person (more cynical folks would call you naive), you might say you’re buying an education. If Michael Spence has made an impression on you, you might say that you’re buying the credential.

By the way, if you’ve ever asked the following question in a classroom – or even been tempted to – you’re buying the credential, not the education:

“Is this a part of the syllabus?”

And I’ve yet to meet a student (to be clear, myself included) who hasn’t asked that question.

But hey, it’s Econ101. If you’ve asked the question, you are minimizing learning. You are learning, but only to get on the path to maximize marks. Marks, I would argue, are more about credentials than they are about learning.

You’ve chosen, through your actions, signaling over learning.


 


 

The LinkedIn, Starbucks and Coursera Problem

 

  1. What is LinkedIn’s business? It’s a professional network, and as an economist, I’d argue that one of the things that it does is that it reduces the asymmetry of information. When LinkedIn allows you to “endorse” a person for a particular skill, or it allows you to post results of a test it has enabled you to take, it is allowing you to signal that you are good.
    To whom are you sending this signal? To anybody who views your profile on LinkedIn! LinkedIn is like a degree certificate from your college: you’re signaling that you know.
  2. What is Coursera’s business? It is an online service that gives you access to recorded lectures that you can listen/see on your own time. These lectures are recorded by world-class faculty, so the learning is as good as it can get. Coursera is like a classroom (but arguably a much better one) from your college: you’re learning.
  3. What is Starbuck’s business? Selling coffee? Sure, you could argue that, but it’s more than that. Remember, you’re buying a bundle at Starbucks! Starbucks’ business is providing an environment that allows people to work in a social setting. To work, to network, to relax, to converse – but what it sells you is comfortable environs where you can do what you want to. Starbucks is like the setting in the college but outside the classroom: it’s your peer environment where you can get work done.

 

Now, the problem of education: when you buy a degree from college, you’re getting all three things.

College is a bundle: education | credentialing | peer networks

 


 

LinkedIn Starbucks Coursera
All logos belong to the firm in question

 

And the reason colleges haven’t gone away yet – and won’t, anytime soon – is because there is no business that I am aware of that sits at the center of that triangle as comfortably as college does.

 


 

Nowadays, it is almost platitudinous to say that the educational system is broken. Why, Peter Thiel cites it as an example of thinking that is not contrarian in his book, From Zero to One.

But here’s the thing:

College isn’t broken.

A Coursera course isn’t enough to land you a job these days: fact.

Most of us value, and almost always will value, the friends we make in college: fact.

The college still is the best place to go to to get both of these things together at the most reasonable price.

But:

Learning is broken in colleges today: fact.

 


If you want to go up against college as a business, you need to sell the same thing that college is selling. And the college sells you a bundle.

A business that seeks to do better than college must do better on all three counts, not just on learning. All of the online learning businesses – Coursera is just one very good example – aren’t able to fill all of the three vertices just yet.

And that’s why education hasn’t been truly shaken down by the internet just yet:

Because college today is more about signaling than it is about learning, and because when you pay money to a college, you are getting a bundle.

So what to do? How to solve this problem?

In the next post in this series, we’ll see what other folks who’ve chosen to battle this beast are trying to achieve.

 

India: Links for 11th November, 2019

  1. “The dominance of just one commodity on the riparian trade routes, and their termination in Narayanganj makes one thing clear — New Delhi hasn’t succeeded in expanding the Indo-Bangladesh Protocol (IBP) routes, devised way back in 1972, as a viable transit for the landlocked Northeast. Renewed efforts in this direction, however, are now underway.”
    ..
    ..
    Unlocking the potential of the Northeast via riverine networks. Bangladesh is key.
    ..
    ..
  2. “In 2019, the government said, “There is no conclusive data available in the country to establish direct correlation of death/disease exclusively due to air pollution.” There is an unmistakable sameness in the narrative of successive regimes — notwithstanding the facts presented in a series of studies. Starting with the United Front, NDA I, UPA I, UPA II and NDA II have all chosen almost the same words to question the correlation between morbidity and mortality. It is almost as if morbidity is an acceptable state of living for Indians. ”
    ..
    ..
    A searing takedown of all round apathy when it comes to the most classical pure public good of them all: air.
    ..
    ..
  3. “The challenge is worth repeating: without government munificence and promoter willingness to invest for the long term, Vodafone Idea is really the most vulnerable company in the private sector triumvirate that includes Jio and Airtel. If one had to bet on which one will blink first, one has to bet on Vodafone Idea, or at least one of its two promoters.”
    ..
    ..
    Vodafone is in trouble. By extension, so is India’s telecom sector.
    ..
    ..
  4. ““A student who comes up with ideas for a pulley brake to draw water in a village uses science to think critically and solve problems,” he adds. “Engaging with even such simple mechanisms on your own is better than building a robot based on instructions.” In fact, the NCERT’s 2017 National Achievement Survey — which found that 44% of students in Grade 3 failed to solve daily problems using maths, a figure that jumped to 62% among Grade 8 students — only proves Agnihotri’s statement.”
    ..
    ..
    Learning needs to be made more effective, and less rote based in India. I cannot emphasize this statement enough.
    ..
    ..
  5. “Any history of Indian science thus has to also try to discern how a technical and scientific culture began to withdraw, look inwards instead of growing and expanding its prowess. What social constraints—caste, language, patronage, political upheaval—led to this quiescence of Indian sciences?”
    ..
    ..
    A fascinating, and on balance painfully short introduction to a history of science in India.

Tech: Links for 20th August, 2019

Five online resources that are free, and that help you be a better student in today’s set.

  1. An utterly beautiful way to learn statistics. That is not hyperbole.
    ..
    ..
  2. If you are a data nerd, you will have already heard of Kaggle. If you aren’t, welcome to the club.
    ..
    ..
  3. The magic of Wolfram Alpha. If you aren’t sure about how to start, try the “Surprise Me” link on the home page
    ..
    ..
  4. If you are using Google Classroom, the latest update might interest you.
    ..
    ..
  5. Try the Socratic app?

Links for 31st May, 2019

  1. “For economists, the idea of “spending” time isn’t a metaphor. You can spend any resource, not just money. Among all the inequalities in our world, it remains true that every person is allocated precisely the same 24 hours in each day. In “Escaping the Rat Race: Why We Are Always Running Out of Time,” the Knowledge@Wharton website interviews Daniel Hamermesh, focusing on themes from his just-published book Spending Time: The Most Valuable Resource.”
    ..
    ..
    Almost a cliche, but oh-so-true. The one non-renewable resource is time. A nice read, the entire set of excerpts within this link.
    ..
    ..
  2. ““Bad writing makes slow reading,” McCloskey writes. Your reader has to stop and puzzle over what on earth you mean. She quotes Quintilian: “One ought to take care to write not merely so that the reader can understand, but so that he canot possibly misunderstand.” This is harder than it sounds. As the author of several books, I’ve learned that many readers take out of a book whatever thoughts they took into it. Still, what else is worth aiming for if you want to communicate your ideas?”
    ..
    ..
    As the first comment below the fold says, she herself doesn’t follow her own advice all the time (and yes, that is putting it mildly), but the book that Diane Coyle reviews in this article is always worth your time. Multiple re-readings, in fact. Also, I am pretty good at writing bad prose myself, which is why I like reading this book so much.
    ..
    ..
  3. “Popper acknowledged that one can never know if a prediction fails because the underlying theory is false or because one of the auxiliary assumptions required to make the prediction is false, or even because of an error in measurement. But that acknowledgment, Popper insisted, does not refute falsificationism, because falsificationism is not a scientific theory about how scientists do science; it is a normative theory about how scientists ought to do science. The normative implication of falsificationism is that scientists should not try to shield their theories by making just-so adjustments in their theories through ad hoc auxiliary assumptions, e.g., ceteris paribus assumptions, to shield their theories from empirical disproof. Rather they should accept the falsification of their theories when confronted by observations that conflict with the implications of their theories and then formulate new and better theories to replace the old ones.”
    ..
    ..
    I wouldn’t blame you for thinking that the author of this essay should read the book reviewed above first – but if you aren’t familiar with falsification, you might want to begin by reading this essay.
    ..
    ..
  4. “Upheaval, by Jared Diamond. I’m a big fan of everything Jared has written, and his latest is no exception. The book explores how societies react during moments of crisis. He uses a series of fascinating case studies to show how nations managed existential challenges like civil war, foreign threats, and general malaise. It sounds a bit depressing, but I finished the book even more optimistic about our ability to solve problems than I started.”
    ..
    ..
    Bill Gates has this annual tradition of  recommending five books for the summer – and I haven’t read a single one of the five he has recommended this year. All of them seem interesting – Diamond’s book perhaps more so than others.
    ..
    ..
  5. “Books don’t work for the same reason that lectures don’t work: neither medium has any explicit theory of how people actually learn things, and as a result, both mediums accidentally (and mostly invisibly) evolved around a theory that’s plainly false.”
    ..
    ..
    To say that I am fascinated by this topic is an understatement – and I have a very real, very powerful personal incentive to read this especially attentively. That being said, I can’t imagine anybody not wanting to learn about how we learn, and why we learn so poorly.
