Ask HN: How can I learn macroeconomics properly?

111 points by techsin101 ↗ HN
Last 3 years has shown that to be a good investor you need to know macroeconomics, specially in context of USA which bring stuff interest rate, QE, bonds pricing, commodity prices, and many similar things which are interconnected. I have lot of general knowledge but I want to be at an expert level of knowledge in predicting/understanding what feds, markets, rates are gonna do and why.

There are 2 groups of people who spend a lot of time thinking about macro economics.

1) Professors who compete for prestige and make fun sounding theories like MMT and tend to have very little skin in the game if their theories create value.

2) Portfolio managers who stand to make or lose enormous sums of money if they can make detailed and accurate predictions based off of macroeconomic analysis.

I'd rather spend my time listening to group 2. If you want to listen to what people like that are thinking about markets in real time, there are plenty of youtube channels and podcasts where you can do that:

Recently my favorite is blockworks Macro (diverged off a crypto channel but this is their non crypto macro content) https://www.youtube.com/channel/UCkrwgzhIBKccuDsi_SvZtnQ

If you want to understand what some of the lingo and concepts mean, NPRs whiteboard series is where I send most people

good distinction. 'applied' macroeconomics is what I really want

Most will never say the truth or the whole truth in public unless you are paying them or they can back their words with their portfolio. “Show me where your money is.”
I recommend watching the pensioncraft videos on YouTube, created by an ex USB macro strategist
Did you mean UBS perhaps? :-)
That's where USB Type C shines. It works whichever way you plug it. /joke.
Go to your local library and check out some Econ books. There’s got to be some Econ classes available online as well.

Economics is one of the most important disciplines to understand even at a base level. So much of the world and human behavior can be explained in terms of supply and demand.

This might be a specific aspect of Global Macro investing, but if you are interested in Risk Parity strategies (as popularized and adopted by Bridgewater), below two books by Alex Shahidi of Evoke Advisors cover Risk Parity asset allocation in great detail:

1) Risk Parity: How to Invest for All Market Environments

2) Balanced Asset Allocation: How to Profit in Any Economic Climate

Before I answer the question, let me preface this by saying that I'm no expert.

I've always felt that macroeconomics is a subject that's best learned from a tutor. There are so many different concepts in macroeconomics that you need to get a good grasp on. Each of these concepts are equally as important as each other and there are so many of them that it's hard to learn everything on your own. You can read all the textbooks and see all the YouTube videos you want but there is nothing like having someone highly specialized teach you the material and help you apply it.

If you don't have the time or money for a tutor, try taking a macroeconomics course at a local community college. This option will be cheaper than hiring a private tutor but still provide you with the guidance and direction you need to learn macroeconomics properly.

Best of luck!

First, it's important to remember that many macroeconomists are economists, and many are not.

Economists focus on the economy and how it affects individuals, businesses, and society as a whole. Macroeconomists look at the big picture: GDP growth, unemployment, inflation, productivity growth, business cycles, and so on.

Macroeconomics is the study of how national economies work. It looks at things like gross domestic product (GDP), unemployment rates, and inflation rates.

It also tries to figure out why some countries have high or low economic growth rates compared to others.

The key question macroeconomists ask is: How can I learn macroeconomics properly?

https://youtu.be/NVnbFQjqh5o is a good overview - Raoul Pal really knows his stuff
Raoul is great, and its always good to hear from industry professionals (rather than bloggers or people who sound like they know but only ever worked as an engineer or whatever) He is a salesman though and seems a bit of a shill now.
Raoul was excellent, and I can highly reccommend any of the pre ~2019 content - he is now a born again Crypto shill.
I think you are more interested in knowing how policy makers react to macroeconomics situation. I believe reading economical history is a good start. Definitely not an expert myself.
I don't think it's possible to learn macroeconomics "properly", in the sense that one can learn e.g. quantum physics "properly". I pick quantum physics because not every expert agrees on some of the tail end of theoretical things, but there's broad agreement on the main parts of it. Those main parts are more than the average person will ever need to use.

This is not remotely true with respect to macroeconomics. It's absolutely routine that you can find even two orthodox economists (or hedge fund managers, or other practical folks if you prefer) who look at the same situation and predict incompatible outcomes. You don't even need to go down the various heterodox rabbit holes; people ostensibly operating from the same theory routinely make opposed predictions.

It's still worth learning some of the vocabulary, because it is useful for understanding what people are talking about. Of course learning is also gratifying for its own sake, and don't let anyone dissuade you if that's what you're up to. Still, I don't think it makes sense to learn macroeconomics on an expert level for a practical purpose. I don't think it's possible to define what an "expert level" even is.

The saying goes, "if you want three opinions, ask two economists looking at one set of data".
"Give me a one-handed economist! All my economists say ‘on the one hand… [and then] on the other.'"

President Truman

You can still learn the theories. Even though they disagree most economists can look at some data and agree what Hayek, Keynes or Friedman would say about it.
>there's broad agreement on the main parts of it

>This is not remotely true with respect to macroeconomics.

Macroeconomists agree largely on most econ topics. Probably anything you'll find in undergrad (and most grad) macro textbooks the majority will agree on.

As evidence, here's [1] a useful site with polls dating back a decade of ~100 of the world's leading economists. Even on these hard questions you'll find they tend to agree quite well. They agree even more on topics not as near the fringe as these questions.

[1] https://www.igmchicago.org/igm-economic-experts-panel/

The agreement v disagreement thing is a symptom of:

Macroeconomic models can't predict the future.

The agreed upon physics models can predict the future to a crazy high level of precision. Even the ones we know are not 100% accurate.

So, it's basically a waste of time to spend too much time learning macro. It's largely useless.

You probably want finance as much as macro. Take a master's degree (not sure if these are as common in the US as in Europe). This stuff is hard, you need to spend time on it. Failing that, follow the advice of lesswrong and read textbooks.
Textbooks won't tell you about Brent Johnson's Dollar Milkshake theory. They also won't have insight on todays inflation and whether it's more similar to the 1970s or 1940s. Textbooks are great for finance fundamentals, but shouldn't be the sole source of macro.
I personally _love_ Thomas Sowell's work. Basic Economics would be a great start, especially now with the current housing crisis. Very amusing and interesting read aswell.

He's got quite a few (albeit politically tinted) interviews with the Hoover Foundation on Youtube.

I have a degree in economics. Both of my parents have PhD’s in economics from MIT and were professors of economics with dozens of published works. I grew up around economists including multiple Nobel prizes winners in economics.

None of this has anything to do with being good at investing on a personal level. Like nothing, in fact I would argue that it’s probably harmful and in my experience causes people to overthink things.

Economics as a profession has a fucking terrible track record of predicting financial markets or broad macroeconomic trends. At this point I’m not sure it’s even clear what economics is for but I can say with confidence that it’s definitely not the place to start if you want to get better at investing.

Agree very much with this. Have an economics degree, PhD from a finance department (although my research was not finance). Personally, with a solid grasp of calculus II, I breezed through my economics degree. Including graduate level courses. My two cents are that an understanding of stats and honing probabilistic intuition (a devilish thing to do) is much more important. Of course, the basic education helps you grok things, how/why a central bank influences an economy, but you may be led astray if you put too much faith into things like the Phillips curve. I would suggest reading any respected macro textbook as well as Hull for learning how financial instruments are priced. You’ll quickly learn that diversifying will get you 95% of the way there with 100% of your mental well-being intact. If you want to be fancy at your cocktail parties, throw a Markowitz optimization over your portfolio. Unless you are willing to devote your entire time finding an edge, you just will not be able to compete with hedge funds and their arsenal of tools, chief among them is a constant stream of intelligent and well paid people to devote their entire time doing it.
Pretty much what I was thinking, but thank you for bringing some authority so it's not just an opinion.
Here's a list of podcasts that touch on macro: - Eurodollar University - The Grant Williams Podcast - Grant's Current Yield - Hidden Forces - Inside Baseball with Old Chestnut - Keeping it Simple with Simplify Asset Management - Library of Mistakes - The Macro Compass - Macro Musings - The Macro Trading Floor - Macro Voices - The Market Huddle - Money Sense - On The Margin - Real Conversations - Real Vision Daily Briefing - The Rebel Capitalist Show - Super Investors and the Art of Worldly Wisdom - Wealthion

The best thing you can do is be open to hearing all opinion/theories. Some people will contradict others, but over time you figure out who is right and who is not.

In addition, I also watch a few indices in my stock app for a high level overview. These are the treasury yields, corporate credit spreads, dollar index, s&p 500, nasdaq, etc. I used to follow much more, but it's not needed for higher level macro.

Isn't macroeconomics a good candidate field for being disrupted by deep-learning algorithms?
You're so, so far behind it's not even funny. Economists have been using statistics, programming, deep learning, etc... for a while now.
I know... the question is: when does the DL take over entirely?
When it's general purpose AI?

I mean, economics in industry is already basically all ML... On the academic side there's a bunch of disciplines and rightfully so.

Having read threads here on economics I can confidently say, don't start by asking a technology forum.

That said, Romer's Advanced Macroeconomics, Acemoğlu's Intro to Modern Economic Growth and Ljungqvist and Sargent's Recursive Macro Theory are good books.

But if you want to be a good investor, just put your money into index funds. You'll easily outperform a large majority.

edit: in addition, the topics you're looking for are only very loosely related to macro. You're looking more into monetary policy, asset pricing and financial economics. Don't take the advice of people who bundle them all together.

I suppose investors want to optimize "we told you before, we are right".
It sounds to me like you're interested in "financial economics" or "money & banking."

Having an interest in these topics myself, I find that they are less about macroeconomics as a whole, which, in the mainstream formulation, is about national income accounting, aggregate demand, general equilibrium, production functions, the business cycle, etc., and are more about the microeconomics of particular markets e.g. the market for money, the market for bonds. I'd have a solid grasp of microeconomics, and then learn national income accounting (`C + I + G + X - M = Y` i.e. the sum of consumption, investment & government spending, less imports equals the national income (GDP/GNP), as well as the capital accounts identities), some ideas about the business cycle and maybe a bit about aggregate demand. Then I'd dive into something purely about money and banking. You'll have the tools you need to think about how markets work, and ideas like the efficient market hypothesis should make sense (within the frame of the model).

I learned this stuff in school, so it's hard for me to give great concrete advice beyond topics, but I've heard good things about Sowell's "Basic Economics," Malkiel's "A Random Walk down Wall Street," and then a personal favorite of mine Vernon Smith's "Rationality in Economics." The latter is truly insightful, but might be difficult if you don't have some of the ground matter (e.g. "what are supply and demand?" "What is a firm?") covered first.

think this is first useful response. Everybody else saying "you don't need to be interested in that" to the OP's question. It may be true that macro is irrelevant to the OP's objective of being a good investor.

I will check out your suggestions. Curious, is it useful at all to understand macroeconomics at a high-level? How does it affect individuals and families in the middle class? Who is in-charge of the macroeconomics of countries and how do we trust them to do the right thing?

Honestly. Start with learning what very basic economics is - "Wealth of Nations", "Human Action", etc and then try extrapolating your perception based on mastery of the principles. In practice this means deciding for yourself.

Modern macroeconomics is an extremely controversial field to say the least and if you start from top (the propaganda-like crazy statements that both sides make), the result would be that none of the viewpoints would ever make any sense to you :)

Starting with Wealth of Nations in 2022 is a very odd choice.

Manikw and Krugman are on the opposite aisles of the political divide. But you'll find the same content in both their textbooks. Basic macro is not even remotely controversial.

Perry Mehrling's "Money and Banking" [1]. What I enjoyed about this course is that Mehrling focuses on how the economy works _mechanistically_, on what is actually happening on balance sheets throughout the economy. For me, this really pulled back the curtain on exactly the stuff you mention above (interest rates, central banks, QE).

Upvoting, I enjoyed the course as well.
This is the closest to what OP is asking. This course is easily digestible for anyone without a background in finance.
Go to a prestigious school? I dunno. Macro Econ is more policy and less baked in the math compared to micro. I think the fundamentals in micro are more rigorous though the one tenant of the whole field — that people act rationally and seek to maximize their utility on things — is bogus. People are dumb or at least often irrational. Groups of people though might act rationally. I think the modeling for micro that makes the most sense is the theory behind firms and how firms operate.
With full warning that it is heterodox, stock-flow macroeconomic models (lots here on it at the Levy Institute: https://www.levyinstitute.org/publications/a-stock-flow-appr... ) is another framework for macroeconomic thinking which is a great supplement to traditional equilibrium-based approaches. I happen to find stock-flow models resonate better with my own intuitions.
