What Rich Family Ruled Florence for Almost Three Hundred Years?

A lot has changed in the Italian metropolis of Florence in the roughly 700 years since the 1427 demography, but a hitting new paper from Guglielmo Barone and Sauro Mocetti shows that one matter has changed less than yous might think — the genealogical limerick of who is rich and who is non.

Conventional studies of economic mobility generally look at the change across one generation — typically comparing the incomes of fathers and their sons. These studies evidence that mobility varies significantly from land to country, with a relatively depression 0.ii percent elasticity of income in the Nordic countries and a relatively high 0.5 percent elasticity of income in places similar the Great britain, the US, and Italian republic. An elasticity of 1 would mean that income status is perfectly inherited between father and son, whereas an elasticity of 0 would mean no inheritance.

The important thing is that even a relatively high elasticity implies a smashing bargain of mobility in the long run. An elasticity of 0.5 in one generation implies 0.25 in two generations and 0.125 in 3 generations. Equally Gary Becker and Nigel Tomes ended dorsum in 1986, "About all the earnings advantages or disadvantages of ancestors are wiped out in three generations."

Barone and Mocetti show that, empirically, this is not the case, and there is meaningful income persistence across seven centuries in Florence. Their paper adds to earlier work past UC Davis economic historian Gregory Clark, which reached a similar determination with regard to Sweden going back to the 17th century. The implication is that there'due south much less economic mobility over the long run than brusk-term figures would lead yous to believe — even in the countries where short-term mobility is very high.

Today'south rich Florentines had rich ancestors

Studying beginnings over the very long term is difficult, but Barone and Mocetti took reward of a surprisingly detailed set of taxation records left backside past the city of Florence in 1427 and the fact that in Western societies surnames tend to pass lineally from father to son.

The table below shows some of their most striking findings. They looked at 2011 income data to identity the v highest-earning surnames in nowadays-twenty-four hour period Florence. They so looked back at 1427 data to detect data about the earnings and occupations with those aforementioned five surnames 700 years agone. For privacy reasons, they and then replaced those surnames with the letters A, B, C, D, and E.

Barone & Mocetti

They show here that the iv highest-earning surnames of 2011 were all higher up-average surnames back in 1427. Indeed, three of the four were in the top x percent.

This is much greater intergenerational income persistence than could possibly be accounted for by even Italy's relatively high 0.5 per centum elasticity. It'south also remarkable considering the massive political and social upheavals that have occurred in the city during this time — including several episodes of strange conquest and domestic revolution.

The situation in Sweden seems to be similar

One might, of class, see this as only a curious fact about Florence. But Gregory Clark conducted a similar report of Sweden and had a broadly similar finding.

He did not take admission to historical income information, so instead he exploited the fact that when surnames were introduced in 17th-century Sweden they had potent grade implications. A defined group of noble families had surnames based on the names of their noble houses. A larger group of middle-class craftspeople adopted a proper name based on their profession. Peasants unremarkably adopted a name based on the showtime name of their father — a proper noun like Andersson for a guy whose dad was named Anders.

What he showed was that hundreds of years afterwards in 2008, people with surnames indicating great-great-great-cracking-great-great-great-peachy-grandparents who were members of the nobility were drastically more probable to be in the Swedish financial elite than people with the surname Andersson.

On the one hand, this is less surprising than the Florentine example, since Sweden has had less political upheaval than Italy and the 17th century is much more contempo than the 15th. On the other hand, it's more surprising, since Sweden has had much more explicit income redistribution than Italia and has a much greater level of measured economic mobility.

What's going on here?

The most plausible explanation of this information is that only projecting i generation of mobility out across three or four or 30 generations is misleading. Income and occupational social status are linked, but only imperfectly so.

It's not unusual for the child of an economically successful professional to attend an elite educational institution and then move into an creative or academic or nonprofit career or political career that might however involve traveling in elite circles but at a much lower salary level than his father's. If the professional's grandson so likewise attended an aristocracy college and moved into a high-paying career in business and police force, statistics would show a great bargain of economic mobility while mutual sense would indicate 3 generations' worth of a loftier-status family.

Shared family access to real estate assets, social connections, a common gene pool, and elite educational institutions could allow for a great deal of long-term entrenchment even as a shut-up view appeared to show instability as people shift in and out of different fields.

The truth, however, is that we don't really know what's going on. Short-term mobility is much easier to report than long-term mobility, since the records are much more precise and consummate. The important thing to know is that as best every bit we can tell, short-term mobility does non translate into long-term mobility — even in countries like Sweden where brusk-term mobility is very high.

So on the one hand, Becker'south reassurance that nosotros don't need to worry nearly inequality because long-term mobility is high seems incorrect. On the other hand, the notion that Sweden-fashion policies are good because they promote long-term mobility also seems wrong. Peradventure mobility itself is an inherently misguided social goal.
