A Conversation with Aja Raden, Garvin Jabusch, and Erika Karp
What if markets don’t merely price reality—but price the stories we tell about reality?
That question anchored Green Alpha’s recent webinar, Engineered Scarcity: Diamonds, Disruption, and the Future of Value, featuring bestselling author, filmmaker, and scientist Aja Raden alongside Garvin Jabusch and Erika Karp. Rather than focusing solely on diamonds, the discussion explored a broader idea: how narratives create economic value, why technological innovation eventually dismantles those narratives, and what investors can learn from the process.

Key Insights from the Discussion
Markets Trade on Stories Before They Trade on Fundamentals
Opening the discussion, Erika Karp observed that equity markets have always been driven by stories. Technologies, companies, and entire industries derive value not only from their underlying economics, but from the narratives investors collectively choose to believe.
Those stories can persist for decades. They can also collapse with surprising speed.
Understanding that transition may be one of the most important advantages an investor can possess.
Diamonds Were Never Just About Scarcity
Using the history of De Beers as a case study, Aja Raden explained how one of history’s most successful marketing campaigns transformed an abundant commodity into a cultural necessity.
As diamond discoveries accelerated in South Africa, the challenge wasn’t finding more diamonds—it was convincing the public they remained rare. Through control of supply, coordinated distribution, and one of advertising’s most iconic campaigns, De Beers didn’t simply sell gemstones; it reshaped cultural expectations around love, commitment, and status.
The result wasn’t merely demand. It was a narrative that endured for generations.
Technology Eventually Breaks Every Artificial Premium
While stories can be remarkably durable, they cannot indefinitely overcome technological reality.
Garvin Jabusch highlighted how lab-grown diamonds illustrate a broader economic phenomenon: when innovation delivers an equivalent—or superior—product at dramatically lower cost, incumbent industries often respond by reinforcing the narrative rather than changing the economics.
History suggests that strategy has limits.
Eventually, substitution wins.
The Real Opportunity Is Recognizing Narrative Collapse
The discussion repeatedly returned to a simple investment question:
How do investors profit when long-standing narratives begin to fail?
Rather than attempting to predict exactly when markets will change their minds, Garvin argued that investors should focus on the companies enabling the transition itself—the technologies removing bottlenecks, improving functionality, and delivering better economics.
The opportunity often lies not in defending yesterday’s narrative, but in owning the infrastructure of tomorrow’s reality.
Consumer Behavior Follows Identity as Much as Utility
One of the most engaging conversations centered on electric vehicles.
Rather than framing adoption as purely a technological question, Aja argued that products succeed when they align with consumers’ existing identities and aspirations. The challenge for many emerging technologies is not simply proving they work—it’s telling a story that resonates with the people expected to adopt them.
Technology may change first.
Consumer narratives often change later.
Understanding that gap helps explain why markets frequently move in stages rather than all at once.
Why This Matters
Every generation inherits stories about what is valuable.
Some prove durable because they reflect genuine economic reality.
Others endure only until innovation makes them impossible to sustain.
For long-term investors, one of the most important questions may no longer be What is scarce? Instead, it is:
Which forms of scarcity are genuine, and which are simply narratives waiting to encounter a better technology?
That distinction has shaped markets before.
It will almost certainly shape them again.
