Rome’s Economic Suicide with Lawrence Reed and Marc Hyden

Colosseum

Ancient Rome went from a thriving civilization to a dystopia before its eventual collapse. My guests today explain how that happened. Lawrence Reed and Marc Hyden co-authored “The Slow-Motion Financial Suicide of the Roman Empire.” Lawrence is the President of the Foundation for Economic Education, and Marc is a political activist and amateur Roman historian.

Many accounts of the fall of Rome focus on military problems and the barbarian invasions. However, the Empire was in decline long before the barbarians showed up to finish it off. The barbarians didn’t kill the Roman Empire; the Roman Empire committed suicide. There were six important factors in the Empire’s decline:

1. Political violence became normalized.

The populist reformer Tiberius Gracchus redistributed public farmland to Roman citizens. His reforms angered the Senate, and his political enemies clubbed him to death in 133 BCE. This was the first open political assassination in Rome in nearly four centuries, but it wouldn’t be the last. Suddenly, it became acceptable for powerful Romans to kill their political enemies, and this would spell doom for Rome’s republican government.

2. The Roman state gave ever-increasing amounts of free food and entertainment to the masses.

Despite having killed Tiberius Gracchus, the senate did not repeal his reforms in an effort to assuage the masses. Tiberius’ brother Gaius Gracchus would take his brother’s position and further his reforms, also introducing a system of subsidized grain for the masses. When Gaius also succumbed to political violence, most of his reforms died with him, but not the grain dole. The dole was retained and expanded, proving a huge burden on the Roman state. Successive generations of Roman leaders would buy political popularity with panem et circenses (bread and circuses). The Roman people came to value the dole over all other values. When the emperor Caligula was assassinated, there was a brief opportunity to restore the Republic, but the people preferred the rule of strong men who could provide them with ever more panem et circenses.

3. Roman armies became personally loyal to their generals rather than being loyal to the Roman state or the people.

In the early Roman Republic, the two elected consuls would raise forces from the eligible land-holding citizenry in times of crisis. These soldiers would return to their ordinary lives upon the completion of the war. This would change with the reforms implemented by Gaius Marius in 107 BCE. Marius expanded military eligibility to the landless masses and granted farmland to his veterans. He also set a precedent for much longer military campaigns (consulships had been ordinarily limited to one year). These changes made the soldiers personally loyal to their generals rather than to the Senate and People of Rome, and the generals would use their military strength to intimidate the Senate. Eventually they supplanted the Senate altogether, turning Rome into an empire with a series of strong men leading it as emperors.

However, the soldiers’ loyalty only lasted as long as the wealth and land kept coming in increasing amounts, as future emperors would discover while wrestling with the Empire’s deteriorating finances.

4. They debased the currency.

The silver denarius was introduced by Augustus with a silver content of about 95 per cent. However, successive emperors, facing ever-increasing demands on the treasury, both from the people who demanded panem et circenses and from the military who demanded ever-more land and money for their loyalty, needed whatever revenue they could get. When taxes would not suffice, emperors would melt down old coins and mint new ones with reduced silver content. During Trajan’s rule, the denarius was about 85 per cent silver. By Marcus Aurelius’ reign, that was down to about 75 per cent. Septimius Severus dropped it to 60 per cent, and his son Caracalla reduced it further to only 50 per cent.

Eventually this would spiral out of control into hyperinflation; emperors couldn’t debase the currency fast enough to keep up with skyrocketing prices. By 268 CE, the denarius was just a bronze coin with a bit of silver brushed on its surface; the silver content was less than one per cent. Nor did they understand the connection between rising prices and currency debasements, which led to…

5. They instituted Draconian price controls.

Rather than halting the debasement of the denarius, the Romans instituted (predictably) disastrous price controls. Dicoletian issued his Edict on Maximum Prices in 301 CE. Diocletian set one price for the whole of the empire, from modern-day Iraq in the east to Britain in the west. In regions where the costs of goods was significantly higher than the legal limit, markets dried up, riots broke out, and many people were put to death for selling at too high a price. The law was so disastrous that it was eventually dropped.

6. They instituted onerous taxes.

Monetary reforms under Diocletian and Constantine switched the empire largely to a gold standard, which was an improvement over the hyperinflationary denarius. However, the benefits of this gold currency were not felt by those outside of the military and the bureaucracy; most people had to scramble to get enough gold to pay their taxes. People who couldn’t pay were sold into slavery.

When the barbarian invasions came in the fifth century, the people welcomed them as liberators, freeing them from the yoke of the Roman tax collectors.

Hive Mind, IQ, and the Wealth of Nations with Garett Jones

hive_mind_wide

Garett Jones is Associate Professor of Economics and BB&T Professor for the Study of Capitalism at the Mercatus Center, George Mason University. His book, Hive Mind: How Your Nation’s IQ Matters so Much More than Your Own is the subject of this episode.

Hive Mind CoverThe book deals with an empirical puzzle: IQ is a weak predictor for earnings. We all know high-IQ people who live paycheque to paycheque, and lower IQ people who succeed brilliantly. And yet, when we look at the relationship between nations’ average IQ scores and their incomes, the relationship is strong. Nations with the highest average IQ scores are eight times wealthier than nations with the lowest IQ scores. How can we resolve this apparent contradiction?

Garett documents five main channels for the spillover effects of IQ:

1. Smarter people are more patient, they save more and build up more capital.

When economists test people’s patience, high-IQ people tend to be more willing to wait for a larger amount of money in the future rather than taking a smaller sum now. This is important at the national level because savings tend to stay within a country* and fund investments within that country. That means living in a higher IQ nation generally means having more capital available to compliment your labour.

2. Smarter groups are more cooperative.

Economists use the iterated prisoner’s dilemma as an idealized scenario where cooperation is at odds with people’s individual, short-term incentives. Jones looked at the many times economists have studied this in experiments and correlated the cooperation rate in these experiments with the SAT scores of the schools the study participants were drawn from. He found that higher SAT schools produced more cooperation in the iterated prisoner’s dilemma.

In later research, Al-Ubaydli, Jones, and Weel (2014) found that higher IQ groups were more cooperative, but higher IQ individuals were not. A high-IQ person in a low-IQ group would not foolishly cooperate when everyone else was defecting, but high-IQ groups could coordinate on a cooperative solution despite not knowing that they were in a high-IQ group.

3. Smarter people are more informed voters and are more likely to support market-oriented policies.

Caplan and Miller (2010) document the tendency for high-IQ people to think like economists.

4. Smarter groups make more productive team members.

Jones uses “O-ring” technologies (drawing on an idea from Kremer (1993)), in reference to the fatal part that cause the Challenger disaster, to show how high-IQ workers can be indispensable in many sectors of a modern economy. While many economic models assume substitutability between high- and low-skilled labour (e.g. three low-skilled workers can do the work of one high-skilled worker), O-ring sectors don’t have this feature. When one mistake can completely destroy a project, low-skilled workers can have effectively negative marginal products.

5. Peer effects cause those with high-IQ peers take on the behaviours of high-IQ people, implying that low-IQ people in high-IQ countries will be more patient, cooperative, informed, and productive than low-IQ people in low-IQ countries.

It’s well documented in the social science literature that people take on the behaviours of their peers. This effectively multiplies the positive effects of the first four channels by making low-IQ people behave like high-IQ people.

Jones sees a virtuous cycle between IQ and development. Higher IQs lead to better economic outcomes, and better economic outcomes lead to better health outcomes and higher IQs. But despite the great importance of this subject, people have been extremely reluctant to research differences in IQ between groups for fear of finding an unpalatable result. One of Jones’ aims in writing this book is to make it more acceptable for people to do research in this area.

We also discuss Jones’ recent debate with Bryan Caplan on the subject of open borders. Jones’ work on IQ spillover effects give us reason to use caution in supporting open borders.

 

*This is actually another economic “paradox” that economists don’t fully understand. One would expect savings to be invested where they face the highest returns, regardless of national boundaries, but that seems not to be the case.
