Economic Transformation and Cultural Change: Evidence from Two Centuries of French Drama
By combining computational linguistics, econometrics, and formal modeling on a corpus of 1,200+ French plays from 1700 to 1900, this study demonstrates how France's economic transformation from aristocracy to capitalism drove a measurable shift in literary themes from political sovereignty to bourgeois household economics, mediated by peer effects and evolving sensitivity to economic shocks.

Imagine French theater from 1700 to 1900 as a massive, living library of 1,215 plays. The authors of this paper wanted to answer a big question: How does a country's changing wallet affect its changing stories?
To find out, they didn't just read a few famous plays; they used a computer "microscope" (a method called Latent Dirichlet Allocation) to scan the entire library at once. They treated the plays like a giant puzzle, sorting the words into different "buckets" or themes to see what the authors were actually talking about over two centuries.
Here is what they found, broken down into simple stories:
1. The Great Theme Swap
For a long time, French plays were like royal court gossip. The main characters were kings, and the stories were about sovereignty, virtue, and political power. This is what the authors call the "Aristocratic Life" theme.
But as France's economy changed and the middle class (the bourgeoisie) grew, the stories changed too. The kings faded into the background, and the plays started talking about everyday life, marriage, and money.
- Theme A (Bourgeois Life): Stories about social life, feelings, and the daily grind of the middle class.
- Theme B (Household Economics): Stories specifically about money, paying bills, and managing a household budget.
The computer showed a clear swap: As the economy grew, the "King" stories disappeared, and the "Middle Class" stories took over.
2. The Two-Act Play (The Timing Matters)
The most interesting part of the study is when these changes happened. The authors used a statistical tool (like a weather vane for economics) to see how the plays reacted to changes in the country's GDP (its total economic output).
They found the reaction happened in two distinct acts:
- Act 1 (The 1700s): When the economy grew, the plays started talking about social life and feelings (Bourgeois Life). The middle class was starting to feel important, so the stories reflected their new social status. However, they weren't talking about money yet.
- Act 2 (After 1820): France began to industrialize (build factories and railways). Suddenly, the plays started talking about money and household budgets (Household Economics). It took about 30 years of industrial growth before the playwrights started making the financial struggles of the middle class the main focus of their stories.
The Analogy: Think of it like a family moving from a small village to a big city.
- First, they start talking about the new neighbors and parties (Social Life).
- Only after they've been in the city for a while and the cost of living hits them do they start arguing about the grocery bill and the rent (Household Economics).
3. Why Did This Happen? (The Peer Pressure Theory)
The authors built a simple math model to explain why writers changed their minds. They suggest two forces were pushing the writers:
- The "Herd" Effect: Writers look at what their friends are writing. If everyone is writing about kings, you write about kings. If your friends start writing about the middle class, you follow suit.
- The "Reality" Effect: Writers also react to the world around them. If the economy is booming and people are buying houses, writers naturally start writing about houses.
The model shows that these two forces worked together. At first, the "herd" kept the old royal stories alive. But as the economy grew stronger, the "reality" force became so strong that it overpowered the old habits, forcing the writers to switch to stories about money and daily life.
4. The Bottom Line
The paper proves that culture isn't just floating in a vacuum; it is deeply connected to the economy.
- Old France: Stories were about Kings and Power.
- New France: Stories were about People and Paychecks.
The authors used computer science to read the books, economics to measure the money, and math to prove the connection. They showed that as France transformed from a kingdom of kings into an industrial machine, its stories transformed right along with it, moving from the throne room to the kitchen table.
