How Currency and Market Manipulation Destroyed the Roman Empire

We Austrian / free-marketing types usually rave pretty aggressively about the economic (and thus entirely human) ills caused by excessive market manipulation (usually through direct command, subsidy, government spending, etc) and currency manipulation (usually through printing and credit expansion).

(Hey by the way: if you don't know much about topics like credit expansion and what it does, I'm going to be working longer-term on some "Explain Like I'm Five" pictograms or videos to try to simplify how it all works for everyone.)

While more sophisticated forms of these tend to cause problems that are Depression-sized rather than collapse-of-civilization-sized, these kinds of manipulations have negative consequences and fundamentally must have negative consequences. I'll talk about this somewhat staggering claim of inevitability in another post.

But for now, I want to talk about the really heartbreaking case of the collapse of the Roman Empire. It's a case of these manipulative activities being undertaken before anyone understood enough economics to really have a good coherent policy, much less understand the consequences. The point of this is to show a decisive example of this manipulation totally annihilating the greatest empire that ever lived, and hopefully teach us a few lessons that we'll see come back when we discuss the Great Depression and Great Recession of the late 2000's, as well as the Staglfation of the 70's.

I know most of my Roman history by listening to the venerable Mike Duncan of the History of Rome podcast. I highly recommend it, by the way--Duncan is sharp, engaging, accurate, and has a wonderfully dry sense of humor. Also you learn a lot. I'll note here that Duncan is not a free-marketeer like myself (in fact I believe he sortof betrays his more left-y ideologies in some of his social commentary), as to assert the more-or-less neutrality of my source. But note he is basically my one major source, and the rest of it is poking around on Wikipedia, so I'm sure you Roman history PhDs will find a few inaccuracies. Let me know and then go argue with Duncan.

Anyway.

Rome printed coins, which was awesome. Bartering is terribly inefficient and essentially prevents any sort of growth of prosperity (and really limits what you have access to). Currency is one of the best things that ever happened to mankind. Rome also had private property rights and a pretty darn free market. It's just really hard to have lots of economic regulation on a giant empire, especially when you have boats criss-crossing the Mediterranean. There were taxes and tariffs, but people were generally free to buy/make/sell what they wanted and pay people what was negotiated between them. This, of course, made the Romans fairly rich. (I'll admit, before anyone calls me on it, that the Romans had pretty high inequality in their Golden Age, too. But their poorest were a lot richer than most everyone of the rest of the world, and the inequality was way less bad than many of the more royally-commanded economies of the time.)


The tough part about printed money is that you can just keep making more of it (keep this in mind as we start talking about the Federal Reserve), without actually expanding the amount of resources available. When we print a lot of money, we start to get inflation--if you suddenly double the amount of money everyone has (without changing the amount of stuff/labor available), things will just cost twice as much. 

Sounds like it's not a big deal, but when inflation is fast, lots of bad things happen. Germany (in WWII), Venezuela (recently), and Zimbabwe (90's) have seen hyper-inflation from printing money too quickly. When that happens, you can't hold on to any money / save any of it, because it will be worth much less very soon. This generally means people also don't want to sell their stuff for cash, because the cash they get for their stuff will soon be worthless, where the stuff doesn't really lose value. Of course nobody will give loans at all, because when they get paid back, the money's now totally worthless. So you really can't start any new ventures. The economy grinds to a halt and, like we see in all these historical cases, people literally start starving to death. All because we printed too much money.

So this rapid inflation is really, really bad. Just freakin' terrible. And remember it comes from printing way too much money. This is even worse in older economies, by the way, because it takes a lot of time for that new money to show up, so prices go up before people even get that new currency to spend on it.

So that's what the Roman government just did, of course. They started doing it to pay the army, which was growing and extorting the later Republic for continually-increasing wages. So they started printing more coinage, and then realized that they could just reduce the amount of gold and silver in the coinage (most of this happened under Nero; later emperors extended it but not by much), and simply declare the new money is worth as much as the older, gold-rich money.

That is, of course, just silly to believe will work.

The problem of inflation started gradually, but when it got bad, it got really bad really quickly. Part of the problem was that nobody knew for sure why it was happening. When prices went up (which was a mystery), the Roman government started printing even more money with in order to try to alleviate the problem and get more money into people's hands, but this of course made things worse.

So you had crazy-rapid inflation. People started starving. The poor started having to give up their plots of land because they were broke, and land started to consolidate into the hands of the wealthiest. 

Finally a few smarties in Rome (around the time of Aurelian, like 270AD or so) got the message--partway. They restored the level of gold/silver in the coinage and tried to scoop up old coins to get them the heck out of circulation. But they kept printing. The Roman economy was collapsing, and oh-by-the-way the gigantic army they had (to deal with all those Goths being displaced by the advancing Huns) were demanding more money all the time, because their wages kept buying less and less stuff. Because the economy was crap, they couldn't use taxes to pay the army, and so they kept printing to do it.

Just a super-vicious cycle here (getting to its worst in the 3rd century). This economic collapse was part of why we had Brittania and Gaul (France) and Spain declaring independence and trying to set up their own economies. It came at a particularly bad time, as those aforementioned Goths were starting to really beat the snot out of the Romans and ran around plundering what was left of the economy.

Anyway.

284 AD, enter Diocletian, the guy whose well-intentioned attempts to take over the economy put the final nail in the coffin and set the stage for feudalism and the dark ages. The guy ruled for 21 years, which was a pretty bloody long time for the age, and in that time screwed up a lot of stuff. 

Diocletian, who is responsible for such insane amounts of bureaucracy that he brought about the adjective "Byzantine" to refer to something overly-complicated.

So what'd Diocletian do?

First, he started imposing price controls. This is a common tactic in high-inflation situations and, of course, always backfires in a lot of ways. Diocletian created a massive bureaucracy to determine empire-wide prices of everything, from pigs to grain to boats to shoes to forks. I mean, freakin' everything.

He made it law for this to be imposed everywhere, but of course it was really not being enforced in private trade. But since provincial governments were the biggest customers of just-about-everything, it meant that a lot of stuff was sold to the government at way-below-market-value, and those people had to turn around with paltry money and try to buy other stuff at market rates. This caused even more starvation and whatnot.

A well-known (and terrible) secondary effect of price controls is shortages of everything being price-controlled: if it's not profitable to make it, people stop making it. So economic activity ground down even further.

Yet another impact of this policy was that money became even more worthless. It was so bad and so rapid that the government started taxing people "in kind"--that is, taking chickens and nails and cut rocks and even services like distance of transport of goods rather than cash, in order to hopefully get the right proportion of goods they needed for the year, but that of course failed miserably. The government got way too much of some stuff (which now sat totally idle as waste) and not nearly enough of other stuff, which meant Roman troops were running around without stuff like shirts and shoes.

Another truly fascinating effect of this extensive price-control was that people started ditching industries wholesale. If we imagine there's a "correct" market price for something, everyone's goods were under-priced. But some of them were more underpriced, and some of them were less underpriced--a central authority just can't set perfectly-proportional prices, especially over an empire.

So let's imagine that in the free market, a pig is worth 100 denarii and a chicken is worth 25 denarii. A pig is worth 4x a chicken.

Knowing that Diocletian's policy had to be at least a little inaccurate, we can imagine that pigs maybe dropped to 10 denarii and chickens to 4 denarii. This means that pigs are now only 2.5x the value of a chicken. Chickens have become comparatively more valuable. So pig farmers started ditching pigs and moving to chickens, which meant you had pig shortages.

So you can imagine all sorts of goods or services (particularly transport of goods, as it turned out, which as you can imagine is particularly bad) just drying up completely, and others becoming excessively common.

So Diocletian had a great plan for this. In order to keep these industries from collapsing, he made pretty much every single industry into a "Guild," like a shipbuilder's guild or a grain-growers guild or a baker's guild. I mean, everything. And by "Guild," I literally mean that if your dad was a grain farmer, you were bound by law to be a grain farmer. Period, end of story, unless you want to go to jail.

So lots of folks in these massively under-valued industries were forced to keep working in them, and went broke and starved. I mean, Ayn Rand's dystopian fantasy in Atlas Shrugged really pales in comparison to just how awful this is.

Most people that didn't starve had to sell off their assets to a rich person and then go work for that rich person to survive, as that rich person could at least feed and shelter them. So these rich folks collected even more property and also, critically, collected lots of incredibly cheap labor that had absolutely no ability to ever leave, as they never got cash and legally were not allowed to get into a new industry.

Sound familiar? It should: it's serfdom. Under Diocletian--in 21 short years--the Roman economy went from its phase of a totally-messed-up-hyper-inflating market economy to a feudal economy in which the majority of the population was locked in legal serf bondage to either the government or to very wealthy land-owners.

Eventually, these land-owners had so many people under their rule that for purely practical purposes (after the Roman empire totally blew apart in the 400's), the local kings of the new mini-kingdoms just gave these guys legal powers, turning their lands into feifdoms and them into barons/lords/whatever.

After that, it was only further downhill. Food shortages and starvation became the norm, in a time when the army needed to be bigger than ever. Wealthy land-owners started hiding their cheap labor so it wouldn't be recruited away, so now the army was not only short on material, but it was even shorter on manpower beyond the effect of the starving/dwindling population.

And that's essentially how the Roman empire ended--the army couldn't get what it needed (men or materials) to defend against the encroaching Goths, and by the 400's they were doing whatever they wanted. Rome ended pathetically poor after this process of rapid inflation, price control, command economy, and then serfdom killed its productive capacity. Obviously a lot was involved in the collapse of the Roman (Western Roman, really) Empire. I feel passionately that the Romans would have weathered many of these storms (as they had so often before--Rome's many burnings, wars that almost depleted the empire, plagues and famines, etc) had their economy and population not been a gutted husk of its former self.

When it was gone, the money was abandoned entirely for a while, and the economy shrunk further as people reverted to bartering.

It makes the latter episodes of Duncan's "History of Rome" really, really depressing. Just to show how Duncan and I don't quite see eye-to-eye on this, he rates Diocletian as one of his top 5 emperors. I think Diocletian is in my bottom 5 for total impact--Nero may have played the fiddle as the city of Rome burned, but Diocletian played the puppeteer as he turned the entire empire to ashes. All from the well-intentioned notion that the government can take over failing parts of the economy and save them, rather than make them worse.

Dear reader, think about how this example applies to the examples of Germany in WWII, Zimbabwe in the 1990's, Venezuela in the 2000's.

Remember this story well. We'll talk about it when we get to the Great Depression, where I'll thankfully have loads more data about how money-printing and credit expansion caused the stock market collapse, and then how FDR's well-intentioned command of the economy prevented the market from getting back on track until well after WWII was over.

  1. Mmm. My roman history is not great, especially the later periods, but I think you are... oversimplifying the story to make a point. You don't mention *why* they started printing more money - because the Empire couldn't maintain itself on the taxes the population would put up with. Even granting that hyperinflation-followed-by-price-fixing was the cause of the eventual collapse (and I think you overlook political conflict a lot there), it's not clear that collapsing two centuries earlier from tax riots and civil war would have been better.

    Relatedly, I think you over-state how solid Rome's economy was in the first place. I have definitely read history which claims that Rome's collapse was because its economy was based on conquest and looting, not production, and it got to the point where it couldn't conquer-and-loot fast enough to support the size it had reached. Which may have lead to hyper-inflation etc., but again, means that the inflation was a reflection of a more fundamental problem, not just 'the government decided to meddle and screwed up.'

    Similarly, while Diocletian's "solution" to hyperinflation may have instantiated other problems eventually, it held off a collapse that looked imminent before he did it for >100 years. (And even then, you're only looking at the collapse of the Western Empire, the Eastern Empire lasted another 1000 years beyond that.)

    So I'm not saying that the government's actions didn't cause problems eventually, but I think you have an underlying assumption that "if they hadn't done anything, there wouldn't have been any problems!" that needs... significantly more support.

  2. I think you've hit on the fundamental problem of Keynsian economics: "We don't have enough resources to pay for government spending, so if we print money, that'll fix it!" When you don't have enough resources for spending, you don't have enough resources for spending, and printing money doesn't create more resources. Ultimately you're _spending_ manpower, food, wood, rock, etc--printing money makes it feel like you have more in the short-term and totally hoses you in the long-term.

    If they hadn't started over-printing, they'd actually have to god-forbid do some budgeting, but by printing they enriched the state at the cost of those suffering from inflation. Sounds similar to just taxing them to death, but it's worse because it doesn't just take their money, but it grinds the economy to a halt _and_ takes their money, so it's just objectively worse.

  3. Also I object highly to the idea that Roman conquest was a major source of their income. They didn't deplete the areas they took over--they developed them. They sure-as-heck taxed them, but they _incorporated_ territories they took over, rather than taking all their stuff. They of course took stuff, but they depended on the incorporated economies, not the incorporated loot.

  4. (Example: Sicily and Egypt were primary sources of grain, mountainous regions in Europe were primary sources of quarried stone and metals, the forests of the north were primary sources of timber, Thrace was a major source of sheep--these productive regions, whose production grew under the Empire, were its primary source of wealth for its lifetime. Italy didn't produce all that much, comparatively.)

  5. I answered the Keynsian comment on facebook. To respond to the budgeting comment here:
    Budgeting is not magic. The state has required functions, and sometimes (for instance, in the case of a gigantic Empire with not a lot of modern tech and a need to support large armies) those expenses can cost more than the tax base is willing or able to support. They could have said "you know, we're too big, maybe we should pull our borders back," but no state in the history of ever has said that seriously without some disaster forcing their hand. Instead they took a series of economic steps that kept things going for ~250 years in the West and ~1250 years in the East. That's longer than the U.S. has been a country. "They could have budgeted better" is a ... pretty damn poor response to what they should have done instead.

    As to the "the Roman economy relied on expansion to survive" point: *Shrug*. My knowledge of Roman history is weak, like I said. I relay the opinion of a historian who probably knows more about it than either of us, but could easily be wrong. If you care to read his book, I can try to figure out which one it was, but am not going to try and argue the point with you.

  6. Budgeting is hard.

    What Rome did killed millions through starvation, sent millions more into poverty, started the atrocity of feudalism that kept people in bondage and Europe in an economic mire for a millennium, and destroyed the empire. I wouldn't support that decision just because budgeting is hard. Yes, this stuff didn't happen for a few hundred years afterwards. It still happened due to bad monetary and economic policy, and that's just horrifying.

    ReplyDelete
  7. As opposed to killing millions in wars, capturing as many people and making them slaves, replacing the Republic with an Empire and destroying multiple other civilizations as it conquered them? That was happening on a day to day basis right then due to the decisions that the emperors were making. If you think the Empire was a good thing overall (and it sounds like you do), I'm having trouble being horrified by their monetary policy. I also continue to think you're... oversimplifying drastically, if you claim that monetary policy from 200 AD was still a significant influence over things happening 1000 years later.

    ReplyDelete
  8. So we have multiple issues here. I don't have to argue whether unintentional starving of millions is better or worse than the Roman policy of slavery. Whether or not there's slavery doesn't make the disastrous economic decisions any more or any less defendable, so I accuse you of distracting the point.

    To the point of "I like the Roman empire," it's also technically not relevant to whether that was a good or defendable economic policy. The Soviets killing themselves with bad economic policy was super-damaging and was bad, even though I didn't like the Soviets.

    But I do happen to like the empire as a whole, because I think there's good evidence that the well-being of the average person improved dramatically. Obviously not everything they did was good, and it's impossible to say what would have happened had Rome lost its wars with the Latins or whatever, but it was overall very good, yeah, and its collapse was catastrophic for the lives of individual people in Europe, as well as progress in technology, art, philosophy, and basically all things we think of as good. I'm sure you wouldn't argue it was good for Europe for Rome to fall--unless you would, then we're generally agreed.

    Also, Rome didn't destroy civilizations--until the Christian emperors it did a great job of letting locals practice many of their own customs. It changed their political institutions, but that's not an objectively bad thing. But the Greeks and Carthaginians and Egyptians and whatnot kept chugging--they weren't eliminated and their cultures just plain weren't destroyed, that just didn't happen.

    There are also many who argue that the warring times in most of these places before and after the Romans was worse than during Rome--"pax romana," it is called, even though it was only peaceful relative to other times in Europe, rather than totally peaceful.

    Anyway, none of this matters, because none of it would change this monetary policy being a terrible thing that killed people and launched feudalism. Sure, Europe could have gotten itself out of feudalism earlier than it did, so Rome is not _directly_ responsible for feudalism still being around 1000 years later, but there wouldn't have been feudalism if not for Diocletian's economic policies, and feudalism super-sucked, and was apparently very hard to get out of.

  9. Not necessarily decisive, but the von Mises Institute (which is, admittedly, super-Austrian / Free Market) totally backs me up here.

    1) Minor point: Carthage was burnt to the ground and the earth around was salted. How many Carthaginians were actually left over to "keep chugging"?
    2) I feel like you are failing to respond to chope's point. Namely, that although the path Rome took did lead to its eventual destruction, these policies were implemented in times of crisis. Doing nothing also wouldn't have worked. Before you claim that X cause the fall of Rome, you need to first demonstrate that Rome was still saveable at the time that X happened.
    3) Personally, I think I agree with your conclusions on most of this post. Assuming your facts are correct, you seem to have reasonably well demonstrated that government intervention in an economy is not always a good thing. On the other hand this is hardly surprising. If you believe that government intervention can have en effect, you almost necessarily believe that it can have a poor one.

    ReplyDelete
  12. 1) Er, yes. Algeria kept chugging, but Carthage was destroyed. Thanks for the check.

    2) I agree there were crises, but the idea that one can only really respond to fiscal crises with an empire-ending economic solution is silly. "Budgeting is hard." The Romans used inflation early in the Republic as an easy out, and as it drove more and more people into poverty, it had to provide more and more bread, making matters worse. You're right that, had the Army been better kept under control and not so able to exploit the Empire for hundreds of years, the crisis wouldn't have been as bad, and it's possible their own pillaging of the Roman coffers (along with others like Nero, Caligula, Commodus), they would have been able to avoid the problem altogether.

    3) I mean to argue that certain kinds of intervention are always bad--and I argue that purposeful monetary expansion (rather than just printing to limit deflation), price-fixing, and government command/control are always bad, rather than only bad if poorly executed. There are definitely certain government interventions which are good (contract law, environmental regulation, preservation of the Commons, preventing free-rider problems, and other areas where private property can't just fix itself).

    ReplyDelete
  13. 3) Sure. I'm just pointing out that you haven't gotten close to proving these points. Showing that hyperinflation is bad is not nearly the same thing as saying that modest monetary expansion is bad.

    Though relating back to (2), you can't really just say that a policy is bad other than to say that it's worse than the alternatives. Assuming that you believe that the government needs money to pay for its operations, you can't claim that printing money is bad unless you have a universally better alternative way of raising money. It's not like there's a default option that we're comparing everything to here, and essentially every way that the government might try to raise money to pay its bills will cause some problems.

    ReplyDelete
  14. OK. So I've had some more time to think about this.

    A) If the Romans did end up with hyperinflation as a consequence of needing to print money in order to pay the government's operating costs, this means that the government's operating costs must have amounted to a substantial fraction of the empires economy (or else they would not have needed to print enough to cause such serious problems). It sounds like the problem might have been simply that government spending was more than could be supported and that they chose the failure mode that lead to hyperinflation rather than tax-riots or grain riots or failure to pay the legions. If this is the case, perhaps the biggest issue with the chosen solution is that it managed to hide the problem and let things simply get worse for a couple centuries rather than force them to solve the underlying problems.

    B) OK. efogg. If you had a fully operational model of economics, your government would have an optimal rate of monetary expansion for any given set of circumstances. Now, this rate may well be zero in many circumstances (though I guess it would be strange to suspect that the optimum would be exactly zero given that you could push it negative). On the other hand, you seem to have suggested that you agree that the rate should be positive in cases where you need to deal with deflation. So there's an optimum value for monetary expansion in order to put inflation at the best possible rate. I claim that this is not actually the best rate of monetary expansion. Printing money has two notable effects. On the one hand, it leads to inflation. On the other hand, it gives the government more money with which to fund its operations. Now, at optimum levels of inflation, the former effect should have negligible marginal impact as you increase the rate of printing money (because functions have zero derivative at extreme points). On the other hand, in most plausible regimes, the latter effect is going to be beneficial. This suggests that the optimal rate of printing money is going to be slightly larger than what it would be if it were being used solely to fight deflation. Of course when you start printing much more than that, the negative effects of inflation probably overwhelm the positive effects of government income. But usually the optimum value of something is at neither zero nor infinity.

    C) So if you look at the actual effects of printing money it looks like it should be effectively the same as a proportional tax on cash holdings (with some strange effects on long-term contracts to be paid in non-inflation adjusted currency). Phrased this way, it does sound like a pretty silly way to raise money unless you are trying to discourage people from holding onto cash (for example, because you want them to invest their money). That is of course unless there are outside factors. For example, if raising taxes becomes politically impossible but printing money, for some reason, is not.
