19th-Century French Economics

Reading Les Misérables, I noticed two things:

  1. Maruis rented his flat for 30 francs a year.

  2. Jean Valjean “bought” Cosette for 1500 francs.

Now, Marius’ apartment was undeniable a hovel, but considering that Jean Valjean still payed 50X 1 year’s rent for her, he must have parted with a tidy sum.

Now, to get a handle on how much money Jean V. blew on Cosette, I employed two economic models. I call on you, Teeming Millions, to tell me which (if either) model is correct.

MODEL A: The Exchange Rate Model

The current exchange rate is around six francs to the dollar. Therefore, Marius’ place cost about five bucks a year, in 1832 dollars. JV, therefore, paid $250 (50 X 5) for Cosette. $250 in 1832 would be worth at least a few thousand today. Ergo, JV paid about $4000 for Cosette.

MODEL B: The Cost of Living Model

A ratty apartment in The Hood these days will go for about $200/mo (in my town, anyway). For a year, that would be $2400. 50 X 2400 = 120,000. Ergo, JV blew about 120,000 on Cosette.

Which model (if either) is correct?

Neither, cause since then the cost of living has gone down while the value of labour has gone up. You can’t really make a direct comparison.
