Not really about books, but PG found this interesting.
The richest families in Florence, Italy have had it good for a while—600 years to be precise.
That’s according to a recent study by two Italian economists, Guglielmo Barone and Sauro Mocetti, who after analyzing compared Florentine taxpayers way back in 1427 to those in 2011. Comparing the family wealth to those with the same surname today, they suggest the richest families in Florence 600 years ago remain the same now.
“The top earners among the current taxpayers were found to have already been at the top of the socioeconomic ladder six centuries ago,” Barone and Mocetti note on VoxEU. The study was able to exploit a unique data set—taxpayers data in 1427 was digitized and made available online—to show long-term trends of economic mobility.
