Learn Macro by Reading the Paper

Macro, and I’ve said this before, is hard.

But a useful way to start understanding it, at least in an Indian context, is by:

  • carefully reading a well written article
  • understanding and noting for oneself key concepts within that article
  • recreating the charts from that article
    • That includes figuring out the source of the data…
    • … as well as acquiring the ability to build out these charts
  • And most important of all, creating a piece of your own (could be a YouTube video/short, a blog, an Instagram story, a Twitter thread) that helps simplify the article you’ve read.1

Now, Arvind Subramanian and Josh Felman have generously obliged us by writing a well written article. I’ll oblige you by carefully reading it and annotating it, including pointing out key concepts, sources for data and recommendations for building out the charts.

That just leaves the last point for you, dear reader. We’ll call that homework.

Now, the well written article:

For more than a decade, India’s fiscal problem has been on the back-burner, acknowledged as a concern, but excluded from the ranks of pressing issues. Now, however, the problem is back with a vengeance. COVID has upended the fiscal position, and fixing it will require considerable time and effort, even if the economy recovers. This worrisome prospect has prompted calls for the Fiscal Responsibility and Budget Management Act (FRBM) to be dusted off, reintroduced, and implemented — this time, strictly and faithfully. But before we heed them, we need to understand why the previous FRBM strategy failed and how to prevent a repeat. We argue below that the new strategy will look nothing like the current FRBM.

First things first, what is FRBM?

The Fiscal Responsibility and Budget Management Act, 2003 (FRBMA) is an Act of the Parliament of India to institutionalize financial discipline, reduce India’s fiscal deficit, improve macroeconomic management and the overall management of the public funds by moving towards a balanced budget and strengthen fiscal prudence. The main purpose was to eliminate revenue deficit of the country (building revenue surplus thereafter) and bring down the fiscal deficit to a manageable 3% of the GDP by March 2008.

Think of it as a one-person Alcoholic’s Anonymous club. It is of the government, for the government and by the government, and the idea is to wean the government off a dangerous addiction that it is hopelessly affixed to: debt.


By the way, there are many reasons this is a good essay, not the least of which is how well structured it is. The first three sentences in the very first paragraph, excerpted above, point out the problem that is going to be addressed, without using any difficult words or jargon. Then they point out the tool that will be used to address the problem. Then they point out the tool itself has problems. Finally, the explain that the essay is about fixing those problems. And then the essay follows. You might want to keep this in mind when writing your own essays (or indeed creating your own podcasts/videos etc.)


Now, back to the essay:

  1. What is general government debt? Where can I access the data?
    Note the second hyperlink above: I’ve linked to the Fred St Louis page about India’s debt, which itself gets the data from the IMF. Here is the page from the Ministry of Finance’s own website titled Public Finance Statistics. It has not been updated since September 2015. Here is a Motilal Oswal report on the subject that pegs general government debt at INR 157,227 billion. (Exhibit 1 in the report). If you read footnote 3 of that exhibit, two things happen. The first thing that happens is that you realize that tracking down general government debt might take a while. The second thing that happens is you feel a rather large twinge of sympathy for the folks who have tried to do this exercise.
    Figure 1 in the well-written article that we are analyzing in today’s post doesn’t mention a source, unfortunately. So recreating that chart will involve a rather large part of our day – but I would strongly recommend that you do the exercise. If you want to analyze Indian macroeconomic data for a living, this will be a good initiation. And indeed, a write-up about this exercise alone is a worthy addition to your CV!
  2. Second r-g: what is r, and what is g?
    1. “r” is the policy rate, which in our case will be the repo rate. This is available on the homepage of the RBI, top-left, under current rates.
    2. Time series data? Available on the DBIE page, under key rates.
    3. “g” is the nominal growth rate of the economy, and can be found at MOSPI.
    4. A useful thing to do as a student is to try and recreate the chart in the well-written article.
    5. Pts 1 and 2 here will help you get most of the data, and try and use either Microsoft Excel or Datawrapper to recreate the chart.2
  3. Next, what is primary balance?3 Where does one get that data in India?4
  4. Next, this sentence from the article: “Simple fiscal arithmetic shows that debt does not explode when the former (primary balance) is greater than the latter (interest-growth differential)”. What is this “simple fiscal arithmetic”? They’ve explained it in equations 1 and 2 in this paper.5
  5. The next three paragraphs after Figure 1 in the article point out how precarious India’s situation is when it comes to government debt, and why. It is one thing to read about the equation in a textbook, it is quite another to “run” the numbers in practice. Give it a shot, please, and see if it makes sense.
  6. Next, this paragraph from the article:
    “First, India should abandon multiple fiscal criteria for guiding fiscal policy. The current FRBM sets targets for the overall deficit, the revenue deficit and debt. This proliferation of targets impedes the objective of ensuring sustainability, since the targets can conflict with each other, creating confusion about which one to follow and thereby obfuscating accountability.”
    This paragraph is a good way to understand the importance of reading In The Service of the Republic, by Kelkar and Shah (and also to read up about the Tinbergen Rule).
  7. The next three paragraphs after that are a good way to understand what Goodhart’s Law means in practice.
  8. And finally, see if you can explain to yourself why targeting the primary balance is better than other options. Personally, I agree that it is a better target, and I agree that rather than setting down a concrete number to reach, averaging out half a percentage point worth of reduction is better. In essence, what they’re saying is that you shouldn’t try to reach x kilos of weight on a diet, but lose x% body weight every month. As our ex-captain might have put it, process over results. One of our gods advocates this too, as Navin Kabra points out.
    My reservation comes from the fact that sticking to a diet is hard, and that is true whether you’re targeting a process or a target. In other words, it is the ongoing implementation of the plan that is the challenge, not it’s design!
  9. One last point: without creating something that you are willing to put up for public consumption, and highlighting on your CV as an exercise you have done – you haven’t really learnt. Reading either that article or this blog is the easy part – explaining it somebody else is the much more difficult (and causally speaking, therefore meaningful) bit.
  10. Please, do it!
  1. Skipping this last point is missing the point altogether, rascalla![]
  2. Document your learnings as you go along.[]
  3. Read the whole article, please. It’s a good way to clear your understanding of this topic, and it is free[]
  4. The Excel link under Deficit Statistics was down when I tried to access the data. Your mileage may vary.[]

  1. “Was the earlier system, based largely on ASI (Annual Survey of Industries) for manufacturing (registered and unregistered), perfect? No, it wasn’t. Is the MCA-based system perfect? No, it isn’t. Despite problems with MCA, is the MCA-based system superior to the ASI-based one? The consensus (I didn’t use the word unanimity) among experts seems to be that it is.”

    Bibek Debroy’s article discusses Arvind Subramanian’s paper. That excerpt above is probably the best way of thinking about it – and as I’ve said before and will say again: if thinking about GDP measurement doesn’t give you a headache, you aren’t doing it right. By the way, two of the twitter threads this past Saturday were about the same issue: worth reading, in my opinion.

  2. “In manufacturing, the increase in informalisation is due to two reasons, according to a 2018 study by the Indian Council for Research on International Economic Relations: first, because of dispersal of production from larger to smaller units; and second, because of the creation of an informal workforce subject to fewer regulations, the fact that employing contract (or informal) workers reduces the bargaining power of the regular or formal worker, suppressing wages overall.”

    ..
    Indiaspend reviews the state of employment in the country, and finds that there is far too much informalization – but also that this is increasing  over time. In this regard, the best book, by far, to read is Bhagwati and Panagariya’s “Tryst with Destiny”.

    ..
  3. “Indian macro policy has been operating under an implicit 2-4-6-8 framework, which are the targets for the sustainable current account deficit, the desired level of retail inflation, the consolidated fiscal deficit target embedded in law and the aspirational rate of economic growth. There is a need to take a fresh look at this macro policy playbook for two reasons. First, the individual targets have been decided at different points of time by different parts of the economic policy ecosystem rather than emerging from a common analytical project. Two, there are reasons to doubt its internal coherence given that India has rarely been able to meet all four targets simultaneously over the past decade.”
    ..
    ..
    The always excellent Niranjan Rajadhakshya comes up with a useful framework to keep a tab on India’s macro levers: 2-4-6-8 is a very useful mnemonic. The rest of the paper speaks about whether this framework makes sense!

  4. “This crisis has systemic written all over it because the market can no longer distinguish financiers that are illiquid from those that are insolvent.”

    I’m calling it: there’s a major crash just waiting to happen in the Indian equity (not just equity) markets, no matter what is done. Speaking of what is to be done, the five suggestions here make a lot of sense. Andy Mukherjee doing what he does best.

  5. “India’s firm size distribution is excessively small, even compared to other developing countries. Also, complementarily, the number of really large firms are also excessively small. We have a “small is bad” problem. What is driving the small-ness? Is labour regulations responsible for discouraging businesses from “placing too many workers under one roof”? Is there anything else driving or contributing significantly to this trend?”
