How to Keep Up With Economics

James Bailey3 Comments

… other than reading our blog, of course.

I was writing up something for my graduating seniors about how to keep learning economics after school, and realized I might as well share it with everyone. This may not be the best way to do things, it is simply what I do, and I think it works reasonably well.

Blogs by Economists: There are many good ones, but besides ours Marginal Revolution is the only one where I aim to read every post

Economic News: WSJ or Bloomberg

Podcasts on the Economy: NPR’s The Indicator (short, makes abstract concepts concrete), Bloomberg’s Odd Lots (deeper dives on subjects that move financial markets)

Podcasts by Economists: Conversations with Tyler and Econtalk (note that both often cover topics well outside of economics). Macro Musings goes the other way and stays super focused on monetary policy.

Twitter/X: This is a double-edged sword, or perhaps even a ring of power that grants the wearer great abilities even as it corrupts them. The fastest way to get informed or misinformed and angry, depending on who you follow and how you process information. Following the people I do gives you a fighting chance, but even this no guarantee; even assuming you totally trust my judgement, sometimes I follow people because they are a great source on one issue, even though I think they are wrong on lots of other things. Still, by revealed preference, I spend more time reading here than other single source.

Finance/Investing: Making this its own category because it isn’t exactly economics. Matt Levine has a column that somehow makes finance consistently interesting and often funny; unlike the rest of Bloomberg, you can subscribe for free. He also now has a podcast. If you’d like to run money yourself some day, try Meb Faber’s podcast. If you’d like things that touch on finance and economics but with more of a grounding in real-world business, try the Invest Like the Best podcast or The Diff newsletter.

Economics Papers: You can get a weekly e-mail of the new papers in each field you like from NBER. But most econ papers these days are tough to read even for someone with an undergrad econ degree (often even for PhDs). The big exception is the Journal of Economic Perspectives, which puts in a big effort to make its papers actually readable.

Books: This would have to be its own post, as there are too many specific ones to recommend, and I don’t know that I have any general principle of how to choose.

This is a lot and it would be crazy to just read all the same things I do, but I hope you will look into the things you haven’t heard of, and perhaps find one or two you think are worth sticking with. Also happy to hear your suggestions of what I’m missing.

Where’s the Deflation?

Jeremy HorpedahlLeave a comment

Inflation continues to remain stubbornly high in the US. While Core CPI is down to 3.6%, the lowest it has been in 3 years, this is still well above the Fed’s 2% target (the Fed’s preferred Core PCE is a bit lower at 2.8%). But consumers are tired of the cumulative inflation, which, depending on your preferred gauge of inflation, is somewhere around 20% in the past 4 years. Consumers want to know: will prices ever go down again?

The answer is: Yes, and some prices already have declined!

For example, you can look at broad categories of consumer purchases, such as durable goods, which are down almost 5 percent since the peak in August 2022. Durable goods include items such as used cars (down 17.3 percent since February 2022), furniture (down 6 percent since August 2022), and appliances (down 7.2 percent since March 2023).

We can even jump into the nondurables category and look at specific items, such as groceries which seem to be on everyone’s mind. Here’s a list of items and the price decrease since their peak (I ignore a few items where it is only a purely seasonal cycle that made them cheaper in April 2024):

  • Spaghetti and macaroni: -4.3% (Feb 2023)
  • Bacon: -12.8% (Oct 2022)
  • Chicken legs: -10.6% (Aug 2023)
  • Chicken breasts: -14.4% (Sept 2022)
  • Eggs: -40.6% (Jan 2023)
  • Milk: -8.3% (Nov 2022)
  • Cheddar cheese: -9.4% (Sep 2022)
  • Bananas: -2.6% (Sept 2022)
  • Oranges: -14.7% (Sept 2022)
  • Lemons: -12.3% (May 2022)
  • Strawberries: -12.9% in the past year (and down 34.6% since seasonal peak in Dec 2022)
  • Ground coffee: -6.2% (Dec 2022)

It’s true that this is a cherry-picked list: lots of items are at all-time highs! My goal here is to show that, Yes!, some prices will fall. Others may too in the near future. And while it’s also true that most prices are still well above 2019 levels, that’s not universally true. The April 2024 prices of lemons, strawberries, and tomatoes are roughly equal to their April 2019 prices.

And it’s not just food. Natural gas this January was 20% cheaper than January 2023. Regular unleaded gasoline is down 11.6% from 2 years ago (and down 25% from the peak in Summer 2022, but we’ll wait to see what this summer looks like). Even some services, such as airline fares, are down 6.7% from 2 years ago (and down 16% from June 2022).

Some of these price decreases could be due to factors specific to the production and supply of those goods, but another factor is monetary policy. Broad measures of the money supply such as M2 show a decline of about 4 percent in the past 2 years. That hasn’t yet produced overall deflation, but it has probably contributed to the decline in the goods and services mentioned.

Looking at price changes can only tell us so much though, especially focusing on individual item prices. The big picture is that over the past 4 years, wages have increased more than prices overall across most of the income distribution (only the highest quintile lost out on the race between wages and prices). Falling prices would certainly help this trend continue, but most consumers have more buying power than they did in 2019, even if they don’t feel like they do.

“Roaring Kitty” Returns to Social Media, and Reignites Stock Frenzy

Scott Buchanan3 Comments

Back in early 2021, when we were still locked down, bored and restless, and trillions of pandemic stimulus dollars were pouring into our bank accounts to fund speculative investments, Keith Gill took to social media to argue that the stock of videogame retailer GameStop (GME) was deeply undervalued. He appeared on YouTube as “Roaring Kitty,” and on Reddit under an unsavory moniker.  He rallied an army of retail investors on Reddit to buy up shares of GME, which was heavily shorted by big Wall Street firms. As hoped by the Redditors, this led to a “short squeeze,” where the shorts were forced to buy shares to cover, which drive GME price to the stratosphere.  We discussed this phase of the drama here.

The drama continued as the jubilant retailers sucked so much money from short-selling hedge fund Melvin Capital that it ultimately shut down; the Robin Hood brokerage firm widely used by Redditors suspended trading  in GME for a crucial couple of days, leading to suspicions it caved to pressures from the Wall Street firms and threw the retail investors under the bus; and key parties, including Roaring Kitty himself, were called before a Congressional committee to explain themselves. The story of Roaring Kitty and the meme stock craze was turned into a movie last year called “Dumb Money.”

Keith Gill largely vanished from messaging boards in early 2021. But he came roaring back on Sunday (May 11), posting on X a sketch of a man leaning forward in a chair, a meme among gamers that things are getting serious:

It seems that the Kitty has not lost his magic.  That X post has garnered over 20 million views, and apparently triggered a new surge in GME stock (and in other heavily shorted stocks as well, which is a significant knock-on effect). Here is a five-year chart of GME, showing the craziness in early 2021, which then died down over the next couple of years:

GME stock had finally approached something approximating fundamental fair value, with occasional ups and downs, then Roaring Kitty posted his sketch, and, blam, the next day, the stock nearly doubled:

Keith Gill has followed up with tweets of video clips with a fight theme, including Peaky Blinders, Gangs of New York, Snatch, Tombstone, X-Men Origins: Wolverine, V is for Vendetta and The Good the Bad and the Ugly ; get that testosterone out there roiling (typical meme stock Redditors are youngish males).

As of Tuesday morning, GME had nearly doubled again, up to $57. (I am reasonably sure it will plunge again within the next few months, but I am not into shorting, and the options pricing structure does not make it easy to set up a favorable bearish trade here).

This response is not like the world-shaking short squeeze of 2021, but it still shows an impressive power of social media influencers and memes to move markets.

Travel Bleg: Montana

mdmakowskyLeave a comment

I’m going to be in Montana later this summer and I’d like to solicit our readers for travel suggestions. Three days in Helena, two and a half in Bozeman. I will have a car, but Glacier and Yellowstone National Parks are likely going to be too difficult to squeeze in given the brevity. Where should I go? Should food be a consideration beyond basic caloric needs? I know 5 days is shockingly brief for big sky country, but that’s why I’m coming to you!

Accounting Appears Before Literature

Joy Buchanan1 Comment

For a current research project on institutions, I skimmed The Dawn of Everything (2021).

I liked this passage about an archaeological site in Syria. The following items were found in a destroyed village where people are estimated to have lived 8,000 years ago:

These devices included economic archives, which were miniature precursors to the temple archives at Uruk and other later Mesopotamian cities.

These were not written archives: writing, as such, would not appear for another 3,000 years. What did exist were geometric tokens made of clay, of a sort that appear to have been used in many similar Neolithic villages, most likely to keep track of the allocation of particular resources.

In chunks, the book has fascinating stuff like the quote above. However, D-o-E is the second book I have read this year that tries to do too much. A book on “everything” sounds incredibly fun to write, and I’m the type who would try, so I take these as a warning.

What is more intriguing than history? Emily Wilson said it well, concerning some of the oldest records we have of human words:

I think we should stop selling classics as, “These are the societies that formed modern America, or that formed the Western canon” — which is a really bogus kind of argument — and instead start saying, “We should learn about ancient societies because they’re different from modern societies.” That means that we can learn things by learning about alterity. We can learn about what would it be to be just as human as we are, and yet be living in a very, very different society.

Not Crazy: Insurance Premiums

Zachary Bartsch4 Comments

Higher homeowner’s insurance premiums have been in the news. But are we just hearing about the extreme cases? This post is inspired by the FRED Blog post about property and casualty (P&C) insurance premium producer price indices. I dive a little deeper.

The insurance premium data is composed of seven components:

  1. Private passenger auto insurance
  2. Homeowner’s insurance
  3. Commercial auto insurance
  4. Non-auto liability insurance
  5. Commercial multiple peril insurance
  6. Worker’s compensation insurance
  7. Other property and casualty insurance

Non-auto liability insurance is further split up into A) medical malpractice insurance and B) other non-auto liability insurance.*

Why Don’t Full Daycares Raise Prices?

James Bailey12 Comments

We put my daughter on a waitlist for the daycare her siblings attended when she was one month old. Fourteen months later, she is still waiting, and we are looking around for other options. Almost every daycare I contact is full, with many saying their waitlists run into 2025.

This sounds like a classic shortage: demand exceeds supply at prevailing prices. But I am puzzled by such a shortage in the absence of price controls. Why don’t these daycares simply raise prices enough to eliminate their waitlists?

Theories:

  1. The kind of person who runs a daycare is not inclined to act as a ruthlessly efficient profit maximizer. This probably explains some of it, but some of the daycares are literally publicly traded for-profit corporations, and they still have big waitlists.
  2. Daycares deliberately underprice infant care as a loss leader to sell care to older kids. Sure, they could raise prices for infants and make more money today, but they want to make sure their preschool stays full down the road, and the easy way to do that is to keep infants as they age.
  3. This is a temporary dislocation due to Covid. Demand fell off during Covid, some centers closed, then demand came back and the remaining centers are full. Perhaps opening a new center would be a good business, but regulation is slowing this down, or people just haven’t realized the opportunity yet.

I think there is something to each of these, but I still feel puzzled, especially since the most expensive locations seem to have the longest waits (at least here in Rhode Island). I can’t come up with a definite answer without lots more data on prices, waitlist sizes, entry, and exit. But I’d love to hear your theories.

What’s Killing Girls Ages 10-14?

Jeremy HorpedahlLeave a comment

I’m in the process of writing a review of Jon Haidt’s book The Anxious Generation. I wrote some preliminary thoughts a few weeks ago, but I’m diving a lot deeper now, so watch for that review soon. But one of the main startling pieces of data in the book is the dramatic rise in suicides among young girls. Haidt isn’t the first to point this out, but in large part his book is an attempt to explain this rise (as well as the rise among boys and slightly older girls).

This got me thinking a bit more broadly about not just suicides, but all causes of mortality among young Americans. So in the style of my 2022 post about the leading causes of death among men ages 18-39, let’s look at the historical trends for deaths among girls 10-14 in the US.

Data comes from CDC WONDER. The top dark line shows total deaths, and the scale for total deaths is the right-axis. Notice that for total deaths, there is a U-shaped pattern. From 1999 to about 2012, deaths for girls aged 10-14 are falling. Then, the bottom out and start to rise again. While the end point in 2022 is lower than 1999 (by about 9 percent), there is a 22 percent increase from 2010 to 2022.

What’s driving those trends? A fall in motor vehicle accidents (blue line, the leading cause of death in both 1999 and 2022) is driving the decline. This category fell 41 percent over the entire time period: a big drop for the leading cause of death!

But the rise in suicides (thick red line) starting in 2013 is the clear driver of the reversal of the overall trend. Suicides for this demographic in 2022 were 268 percent higher than 1999, and 116 percent higher than 2010. Haidt and others are right to investigate the causes of this trend (I’m not convinced they have the complete answer, but more on that in my forthcoming book review).

There has been no clear trend in cancer deaths over this time period, and the combination of all the three of these trends means that roughly equal number of girls ages 10-14 die from car accidents, suicide, and cancer.

What can we learn from this data? First, we should acknowledge just how rare death is for girls ages 10-14. At 14.8 deaths per 100,000 population, it is the lowest 5-year age-gender cohort, other than the ages just below it (ages 5-9, for both boys and girls). But just because it is small doesn’t mean we should ignore it. The big increase, especially in suicides, in the past decade is worrying and could be indicative of broader worrying social trends (and suicides have risen for almost every age group too, see my linked post above).

If a concern, though, is that we are over-protecting our kids and this is leading them to retreat into a world of social media, we might want to see if there are any benefits of this overprotection in addition to the costs. The decline in motor vehicle accidents is one candidate. Is this decline just a result of the overall increase in car safety? Or is there something specific going on that is leading to fewer deaths among young teens and pre-teens?

As we know from other data, a lot fewer young people are getting driver’s licenses these days, especially compared to 1999 (and engaging in fewer risky behaviors across the board). Of course, 10-14 year-olds themselves usually weren’t the ones getting licenses — they are too young in most states — but their 15 and 16 year-old siblings might be the ones driving them around. Is fewer teens driving around their pre-teen siblings a cause of the decline in motor vehicle deaths? We can’t tell from this data, but it is worth investigating further (note: best I can tell, only about 23 percent of the decline is from fewer pedestrian deaths, though in the long-run this is a bigger factor).

Social tradeoffs are hard. If there really is a tradeoff between fewer car accident deaths and more suicides, how should we think about that tradeoff? Or is the tradeoff illusory, and we could actually have fewer deaths of both kinds? I don’t think I know the answer, but I do think that many others are being way too confident that they have the answer based on what data we have so far.

One final note on suicides. For all suicides in the US, the most common method is suicide by firearm: about 55% of suicides in the US were committed with guns in 2022, with suffocations a distant second at about 25%. For girls ages 10-14, this is not the case, with suffocation being by far the leading method: 62% versus just 17% with firearms. I only mention this because some might think the increasing availability of firearms is the reason for the rise in suicides. It could be true overall, but it’s not the case for young girls.

Proposal: Mandating Hard Prison Time for CEO’s of Companies Whose Consumer Data Gets Hacked Would Cut Down on Data Breaches

Scott Buchanan2 Comments

Twice in the past year, I have received robo notices from doctors’ offices, blandly informing me that their systems have been penetrated, and that the bad guys have absconded with my name, phone number, address, social security number, medical records, and anything else needed to stalk me or steal my ID.  As compensation for their failure to keep my information safe, they offer me – – – a year of ID theft monitoring. Thanks, guys.

And we hear about other data thefts, often on gigantic scales. For instance, this headline from a couple of months ago: “Substantial proportion” of Americans may have had health and personal data stolen in Change Healthcare breach”. By “substantial proportion” they mean about a third of the entire U.S. population (Change Healthcare, a subsidiary of UnitedHealth, processes nearly half of all medical claims in the nation). The House Energy and Commerce  Committee last week called UnitedHealth CEO Sir Andrew Witty to testify on how this happened. As it turned out:

The attack occurred because UnitedHealth wasn’t using multifactor authentication [MFA], which is an industry standard practice, to secure one of their most critical systems.

UnitedHealth acquired Change Healthcare in 2022, and for the next two years did not bother to verify whether their new little cash cow was following standard protection practices on the sensitive information of around a hundred million customers. Sir Andrew could not give a coherent explanation for this lapse, merely repeating, “For some reason, which we continue to investigate, this particular server did not have MFA on it.”

But I can tell you exactly why this particular server did not have MFA on it: It was because Sir Andrew did not have enough personal liability for such a failure. If he knew that such an easily preventable failure would result in men in blue hauling him off to the slammer, I guarantee you that he would have made it his business within the first month of purchasing Change Healthcare to be all over the data security processes.

Humans do respond to carrots and sticks. The behaviorist school of psychology has quantified this tendency: establish a consistent system to reward behavior X and punish behavior not-X, and behaviors will change. As one example, Iin one corporate lab I worked in, a team of auditors from headquarters came one year for a routine, scheduled audit of the division’s operations. If the audit got less than the highest result, the career of the manager of the lab would be deeply crimped. Our young, ambitious lab manager made it crystal clear to the whole staff that for the next six months, the ONLY thing that really mattered was a spotless presentation on the audit. It didn’t matter (to this manager) how much productivity suffered on all the substantive projects in progress, as long as he was made to look good on the audit.

Let me move to another observation from my career in industry, working for a Certain Unnamed Large Firm, let’s called it BigCo. BigCo had very deep pockets. Lawyers loved to sue BigCo, and regulators loved to fine BigCo, big-time. And it would be a feather in the cap of said regulators, or other government prosecutors, to throw an executive of BigCo in the slammer.

Collusion among private companies to fix prices does do harm to consumers, by stifling competition and thereby raising prices. So, back in the day when regulators fiercely regulated, statutes were enacted making it a criminal act for company agents to engage in collusion, and authorizing severe financial penalties. American authorities were fairly aggressive about following up potential evidence, and over in Europe, police forces would engage in psychological warfare using their “dawn raid” tactic: just as everyone had sat down at their desks in the morning in would burst a SWAT team armed with submachine guns and lock the place down so no one could leave. I don’t know if the guns were actually loaded, but it was most unpleasant for the employees.  BigCo’s main concern was avoiding multimillion dollar fines and restrictions on business that might result from a collusion conviction, so they devoted significant resources to training and motivating staff to avoid collusion.

Every year or two we researchers had to troop into a lecture hall (attendance was taken) and listen to the same talk by the same company lawyer, reminding us that corporations don’t go to jail, people (i.e. employees) go to jail, by way of motivating us to at all costs avoid even the appearance of colluding with other companies to fix prices or production or divide up markets or whatever. This was a live issue for us researchers, since some of us did participate in legitimate technical trade associations where matters were discussed like standardizing analytical tests. If memory serves, the lawyer advised us that if anyone in a trade association meeting, even in jest, made a remark bordering on a suggestion for collusion, we were to stand up, make a tasteful scene to make it memorable, and insist that the record show that the BigCo representative objected to that remark and left the meeting, and then stride out of the room. And maybe report that remark to a government regulator. That maybe sounds over the top, but I was told that just such a forceful response in a meeting actually saved BigCo from being subjected to a massive fine imposed on some other firms who did engage in collusion

My point is that if the penalties (on the corporate or managerial level) for carelessness are severe enough, the company WILL devote more substantial resources to preventing fails. It seems to me that the harm to we the people is far greater from having our personal data sucked out of health care and other company databases, than the harm from corporate collusion which might raise the price of copier paper or candle wax. Thus, I submit that if someone in the C-suite, like the chief information officer or the CEO, were liable to say 90 days in jail, management would indeed apply sufficient resources to data integrity to thwart the current routine data theft.

If I were king, this would be the policy in my realm. I recognize that in the current U.S. legal framework, the corporate structure shields management from much in the way of personal liability, and there are good reasons for that. I suppose another way to get at this is to have automatic fines structured to strip away nearly all shareholder value or management compensation, whilst still allowing the company to operate its business. This would be another route to put pressure on management to prioritize protection for their customers. Sir Andrew’s total compensation package has been running about $20 million/year. To my knowledge, the impact of the recent gigantic data breach on him has been fairly minimal in the big picture. Sure, it was aggravating for him to have to tell the U.S. Congress that he had no idea why his corporate division screwed up so badly, and to have to devote a good deal of effort to damage control, but I am guessing that his golf game (if he is a golfer) was not unduly impacted. He is still CEO, and collecting a princely compensation. But what if the laws were such that a major data hack would automatically result in a claw-back of say 95% of his past two years of compensation, and dismissal from any further management role in that company?  I submit that such a policy would have motivated the good Sir Andrew to have devoted proper diligence and company resources to data integrity, such that this data breach would not have happened.

I don’t mean to pick on Andrew Witty as being uniquely negligent. By all accounts he is a nice guy, but his behavior is paradigmatic of ubiquitous benign management neglect, which has consequences for us little people.

These are just some personal musings; I’m sure readers can improve on these proposals.

Brief thoughts from attending SOLE 2024

mdmakowsky1 Comment

I just back from the Society of Labor Economics Meetings in Portland. A couple thoughts in no particular order

  1. Conferences are about both luxuriating and reinvesting in our geographically dispersed social networks. Everything else is a secondary. Its not just that I like seeing these people who speak our language and share our jokes, I genuinely miss them when it’s been too long.
  2. Post sessions are fantastic for applied work. I enjoyed multiple 2 to 4 person discussions with an actively engaged author who had a perfect prop to lean on. Great stuff.
  3. If you’re going to give a keynote, don’t try to impress people, try to educate them on something you specialize it. We all miss being students. Give us a crash course to distract us from the hotel catering.
  4. Portland, and the Pacific Northwest in general, is just beautiful. Go to the Japanese Gardens next time you are there.
