Hanauer contrasts an ergodic game such as rock-paper-scissors, where the next result does not depend on the last, with Monopoly, where ownership, cash, and position accumulate. He argues that market economies resemble the second game because starting position, luck, path dependence, and compounding affect future opportunity. Early success can create more chances to succeed, while bad luck can trigger a downward spiral. The lens changes the diagnostic question from whether a single exchange looks fair to whether the sequence of exchanges systematically concentrates power or excludes participants. It also explains why Hanauer sees a broad middle class as a deliberate institutional construction rather than an automatic by-product of growth.

Core principles
- 01Past outcomes can change the odds of future outcomes
- 02Advantages and disadvantages can both compound
- 03Starting position and luck must be included in causal explanations
How to run it
- 1
Test for path dependence
Ask whether winning or losing now changes the person's resources, choices, or odds next time.
- 2
Map the starting positions
Record inherited assets, liabilities, skills, relationships, and constraints that shape the first move.
Pro tip Include advantages that are easy to overlook because they feel normal.
- 3
Trace the feedback loops
Identify where an advantage produces more advantage or a setback produces further setbacks.
Watch out Do not attribute every difference to effort after compounding has begun.
- 4
Design a counterweight
Where concentration harms the system's purpose, add a mechanism that restores participation or competition.
Watch out A counterweight should preserve useful incentives rather than erase all variation.
In the wild
Hanauer uses rock-paper-scissors as an independent-outcome game and Monopoly as a path-dependent game. In Monopoly, a few favourable early moves generate assets and cash that improve later odds until one player can own everything.
→ The analogy makes accumulated advantage visible in economic analysis.
Common mistakes
Looking only at the latest move
A current outcome can appear merit-based while concealing the accumulated resources that made it possible.
Assuming the analogy proves policy
The lens identifies a mechanism; it does not select a specific intervention without further evidence.
Is it for you?
Best for
It is best for reasoning about wealth, opportunity, market concentration, and long-run inequality.
Not ideal for
It is unnecessary for genuinely independent one-off events where prior outcomes do not change future probabilities.
From the transcript
“Monopoly is a non-ergodic game.”
“It is characterized by luck, path dependence and compounding.”
