My excellent Conversation with Kim Bowes
Here is the audio, video, and transcript. Here is the episode summary:
Kim Bowes is an archaeologist at the University of Pennsylvania whose book, Surviving Rome: The Economic Lives of the Ninety Percent, Tyler calls perhaps his favorite economics book of 2025. By sifting through the material remains of Roman life — shoes, bricks, ceramics, and the like — she uncovers a picture of ordinary Romans who could evidently afford to buy multiple sets of colorful clothes, use gold coins for daily transactions, and eat peppercorns sourced from thousands of miles away. This vast web of commerce, she argues, both bound the empire together and provided the tax base that kept it running — and when it unraveled, Rome unraveled with it.
Tyler and Kim discuss what would surprise a modern visitor to a Roman elite home, what early Roman Christianity actually looked like on the ground, why Romans never developed formal economic reasoning, what decentralized money-lending reveals about the Roman state, whether there were anything like forward markets, why Romans continued to use coins even as the empire debased them, the economics of Roman slavery, whether Roman recipes taste any good, the Romans as hyper-scalers rather than inventors, what Rome made of China and Egypt, why Kim’s not a fan of the Vesuvius challenge, the practicalities of landscape archaeology, how a vast belt of factories along the Tiber Valley went undiscovered until twenty years ago, where to go on a three-week tour of the Roman Empire, what she thinks is ultimately behind Rome’s unraveling, and much more.
Here is an excerpt with some economics:
COWEN: Say, when the government is clipping the silver coins and lowering their silver content, as we now know in economic theory, this will imply at least some inflationary pressure. Are there Roman writers who understood that and laid it out, or they’re just vague public complaints about government clipping the coins?
BOWES: They’re not so much clipping them as they are minting them with less silver, which amounts to the same thing. It’s just a little bit classier and harder to detect. Absolutely, people know that they’re doing this. What I think is most interesting and what we’re all still wrestling with is, from even before Nero onwards, Roman emperors recognized the advantage to the fisc to basically producing coins with less silver.
Then they start to have silver problems, and they start really pulling the silver out of their coins, and nobody cares. That is to say, people care, and they notice, but the convenience of the Roman coin of the realm, the denarius, which is made with silver, outweighs—that’s a little bit of a pun—the actual silver content of that coin, and so people are willing to just suck it up and deal, and they keep using it.
There is inflation, and inflation, we can now tell, thanks to some great papyri from Egypt, trends upwards very slowly over the first century, the second century, the third century, but it’s not proportional to the amount of silver that’s being pulled out of the coins. People basically still have trust in their coinage, which really shows the degree to which the state has convinced people, simply by supporting ordinary people’s coin use, that the coins work and that they’re going to back their coins, even though they’re slightly pulling the silver out.
COWEN: Why was there so much decentralized money lending? You would think that banks would have economies of scale, offer better terms, just like I wouldn’t borrow money from my friends, I would go to the bank. Why doesn’t the Roman Empire evolve that way?
BOWES: The Roman Empire confuses us, I think, because on the one hand, it looks like a really big state that ought to do things that big states do. The Roman big state is really a mask for an empire of friends and family. You borrow money from friends and family. Banks, such as they exist, are really nothing more than friends and family, so even when you have actual banks, they tend to be largely constituted by a single family.
The difference that you’re making between borrowing from a bank and borrowing from your family is much less clear-cut in a world in which the bank is your family, or the bank is a family that is friends of yours. It’s not that Romans don’t use banks, they do use banks. We can see the most often wealthier Romans using banks. It’s a lot harder to see the 90 percent using banks, and they seem to more often default to the immediate circle of people that they know, which again, it’s not such a huge distinction. In a world in which there’s no FDIC, in which the bank isn’t guaranteed and protected by the state in the way in which our banks are, the distinction between bank and family, bank and friends, is much less clear.
Interesting and engaging throughout, definitely recommended. You can buy Kim’s excellent book here.

Both will have watched events in Hungary over the weekend and felt themselves vindicated. Of all the varied reasons for Viktor Orbán’s landslide defeat, the public’s desire to mend relations with the EU was prominent. The election winner Péter Magyar, no kind of liberal, and in fact a former Orbán man, favours a “return to Europe”.” (Ganesh in the FT)

The Nobel Memorial Prize in Economics, 1969-2025
The Nobel Memorial Prize in Economics has been awarded annually since 1969. Who wins the prize is a topic of much interest and tracks the whole course of the academic discipline over the last 57 years. Explaining who wins the prize in any given year is a complex process, which involves the subtle endogeneity of the choice of the field and the individual(s) who should be honoured. Citations, track records, networks of past winners, institutional factors along with field rotation and Economic Prize Committee composition may all play a role. A dynamic sample involving a changing stock of would-be candidates along with a moving flow—both into and out of the sample—add complexities to the modelling. We find robust evidence that the Nobel Prize rotates in a semi-regular way between the fields of economics. Earlier awards were for a single paper, later ones for a body of work. Networks do not matter, but having a Nobel student or co-author does. There is some evidence that the personal preferences of Committee members had an effect on either field or individual winner. The Committee’s decisions changed after Lindbeck retired.

Are we underestimating youth well-being?
Although there is growing evidence that the subjective wellbeing among the young declined in recent years, the evidence is not consistent across surveys. We examine the relationship between age and various measures of wellbeing and illbeing across three major surveys – the Gallup World Poll (GWP, Global Minds (GM) and the Global Flourishing Survey (GFS). The GWP is conducted via face-to-face and telephone surveys; GM surveys are web-based; and GFS uses both telephone and web-based surveys. We focus on 23 countries appearing in all three surveys. The clearest evidence that wellbeing rises with age and illbeing declines with age comes from the web-based surveys in both GM and GFS. The age profiles look very different when surveys are conducted by telephone: the higher rates of illbeing among the young are far less apparent in these surveys. Because survey mode is not randomly assigned, we cannot be sure differences in age profiles of wellbeing and illbeing are causally affected by survey mode. Selection into survey mode, both across and within country, plus differential non-response by survey across the age range, may be playing a role. However, the evidence indicates very different age patterns in wellbeing and illbeing emerge across different survey modes.

That was then, that was then
Fred Anderson has demonstrated how a futuristic novel written in 1763 can help to shed light on British thinking about the long-term consequences of the peace [from the Seven Years’ War]. The anonymously published The Reign of George VI, 1900-1925 presents a scenario far in the future, in the early twentieth century. The book’s counterhistorical narrative suggests that Britain, by granting far too generous a peace in 1763, unintentionally helped France and Russia become leading nineteenth-century world powers. In the early twentieth century, the reign of George VI is thus dominated by Britain’s worldwide struggle to reestablish its position as a global power. The conflict ends with Britain imposing peace in Paris in 1920, after British troops have “liberated” France, with George, the “philosopher king,” hailed as the bringer of freedom. At the time the book was written in 1763, its primary target was clearly the British negotiators in Paris…

Another possible cyberequilibrium? (from my email)
I would not wish to bet on this, but it is an interesting idea:
I wonder if the cyber capabilities of Mythos and future models ultimately lower the returns to ‘hacking,’ perhaps below the point where such efforts are worth investing in.
Say you’re a nefarious actor and uncover a critical, zero-day exploit in an important system. How do you extract the most value from that exploit? There are more valuable and less valuable times to deploy it, and usually the best time won’t be “immediately.” You may only get to deploy it once or a small number of times. You have to consider:
- How long do I expect the vulnerability to persist?
- What material gain do I get by exploiting it at a given time?
- How does exploiting it increase my personal risk (by focusing countermeasures in my direction)?
The answer to (1) is now “a much shorter time than before”, while 2 and 3 are mostly unchanged. In the new world, yes, exploits are much easier to find, but the expected value of a given exploit has also shrunk. The odds of an opportune moment falling within the ‘window of usefulness’ of that exploit are much lower. It’s plausible that the new equilibrium becomes “it’s not even worth spending money to find vulnerabilities in most systems, because the chances of being able to do something useful with it before it’s patched is close to zero.”
Much of the fear around cybersecurity vulnerabilities is something like: our adversaries accumulate a pile of highly damaging (to physical infrastructure, military assets, communication systems, …) exploits, which in the event of a conflict they then rapidly deploy to cause damage. Mythos would seem to favor defense here, because the usable lifetime of any exploit is much shorter. Any cyberattack that is timing-dependent now has lower utility.
Yes, there are more mundane cybersecurity concerns like ransomware or data theft, but these aren’t hugely significant in the scheme of things. And I would expect within a few years we’ll have fairly robust tools for automated vulnerability discovery and patching that any large business that cares about these things can deploy.
No doubt this assumes you can trust those in control of the leading-edge models. But even if you’re a bit behind, the situation may not be so bad. There isn’t an infinite supply of exploits, and again, most of them only need to be found ‘fast enough’ in order to mitigate the damage.

Driving cross-country
I have driven cross-country four times, at least if you count a 3/4 trip as valid. I also have driving experience in virtually all states, including Hawaii and Alaska, neither of which would be part of typical cross-country travel.
I recommend this mode of transport highly, especially for the United States. Here are a few observations:
No matter which route you take, so often Mexican food is your best option.
I most prefer the southern route, involving Memphis, Texas, and southern Utah/north rim of the Grand Canyon. Do I have to tell you no major highways?
The extreme northern route is better than the middle route. Visit Duluth.
The music you bring is essential. While this will depend on your taste, in general try to have some regional music to match your route. Dylan and also folk music sound good in most parts of the country. CDs can be a better medium than online music for these trips. Do not listen to music when you start your day’s drive, however, as you will end up burnt out. Save it for after a few hours of driving. Nor should you listen to too much high energy music. Woody Guthrie is better than Led Zeppelin in this setting.
How much you should roll down car windows, vs. relying on air conditioning, is a critical decision. The correct answer will depend on the route and time of year, but please do not screw this one up. Usually I like windows down, but with raised windows you can hear the music better.
Salads in the Midwest can be good.
In Texas and Oklahoma you may see some amazing storms. Texas is the best state for random food stops.
Use paper maps, GPS may bring you along too efficient a route.
Issues of children aside, optimal group size is two, no larger. To avoid least common denominator effects.
You can do these trips at any pace you want, even an hour in a place can teach you a good deal.
You could do a trip simply by stopping in every interesting place in New Jersey, one of the smallest states.
I prefer Vermont to New Hampshire, at least for driving purposes. I also prefer Montana to Wyoming, the latter for me being beautiful but somehow quite a boring state outside of Yellowstone? You cannot spend too much time in Utah.
Oregon is one state where I never have been driving. Is that a great loss? I know only Portland there.
Driving cross country, or only parts of it, is the very best way to see America.
