6/ Lowest class according to Temin (2006). We assume their average income to be 30% above the subsistence minimum. They account for more than 90 percent of the rural population (which in turn accounts for 90 percent of the total population).

7/ Based on Goldsmith (3.5 HS per day times 225 working days). Temin (2006, p. 138) gives also the average wage in Rome as 3-4 HS per day (see also Milanovic, 2006, Table 4 and the sources given there). Wages expressed at Rome-city prices (see discussion of mean income below). Workers are estimated to account for 80 percent of urban population.

8/ The legion's commander wage ratio (67 times ordinary soldier’s wage) is given in Duncan-Jones (p. 116) who quotes Brunt (1950). The number of legion commanders calculated by dividing 250,000 soldiers by the average size of a legion (5,000 men; for the average size of the legion, see Duncan-Jones p. 215).

# _Discussion._

<u>(1) Slaves and landowners. Slaves are not shown as a separate social category. This is</u> because their economic conditions covered practically the entire spectrum of incomes (with a possible exception of the very top). Their consumption levels varied widely: they ranged from being very rich (owning slaves themselves) to being very poor (mostly slaves engaged in mining). Even rural slaves, who were on average worse-off than urban slaves, were not just “all undifferentiated gang laborers; [on the contrary] there are lists of rural slave jobs that are as varied as the known range of urban or household slave jobs" (Temin, no date, p. 8). For the urban slaves, who were more numerous than rural slaves,<sup>30</sup> the prevalence of manumission made Roman slavery (unlike that in the Americas) an “open slavery”. Schiavone (2000) and Temin (no date) discuss the position of slaves and the role of manumission at great length. Similarly, landowners are not shown separately as a class since most landowners belonged to the four top classes and their incomes from land are included in our totals.

<u>(2) Top of the income distribution. The estimated Gini of between 37 and 40 might seem</u> low in the light of the excesses of wealth in Rome (see Table below with data gathered from Tacitus’s _Annals_ ) But this extraordinary wealth was limited to a very few people at the very top. It is very unlikely that they would be even selected (so few they were) to participate in a modern random household survey. Moreover, their extraordinary wealth was not out of step with what we observe today. For example, the fabulously rich triumvir Marcus Crassus (-115 to -53) whose wealth was estimated at 200 million HS (Schiavone, 2000, p.71) and hence his income at HS 12 million per year,<sup>31</sup> has more than a counterpart in today’s Bill Gates and other super rich. Crassus’s income was equal to about 32,000 mean Roman incomes. Using today’s US GDI per capita, the equivalent would be an income of about $1 billion per year. But this is an income that is easily made by many of today’s hyper-billionaires and yet the overall inequality is not much affected by it. Bill Gates’s fortune is estimated at $50 billion which with 5% interest yields $2.5

> 30 According to  Schiavone (2000,  p.112), slaves represented 35 percent or more of Italy’s population. And Italy was the most urbanized part of the Empire.

> 31 Using the conventional interest rate of 6 percent (see Finley, 1985, p.104).
