Classroom Simulation: "Understanding Market Bubbles" 

Scene: First-year Introduction to Economics Class (See note at the end)
Professor: Dra. Rowe
Students: Nilza, Lynn, Michelle
Topic: Market Bubbles and Their Consequences

---

Nilza (raising her hand):
Professor Rowe, I keep hearing the word “bubble” on the news when people talk about housing or tech stocks. What exactly is a bubble, and should people like us—students—care about it?

Dra. Rowe (smiling):
Great question, Nilza. Let’s explore this together.
Imagine you and your friends all believe a new brand of sneakers will become super valuable. Everyone starts buying them, not because they need shoes, but because they think they can sell them to someone else later for more money.

Michelle:
Like flipping sneakers?

Dra. Rowe:
Exactly! The price of those sneakers keeps increasing—not because they’re getting more useful, but because people think they will keep rising. That’s the beginning of a bubble.

Lynn:
So what causes it to “pop”?

Dra. Rowe:
Eventually, someone says, “Wait… these sneakers aren’t worth that much,” and they stop buying. Then, more people realize the same thing. Prices drop fast, and people panic. That’s when the bubble bursts, and the market crashes.

Nilza:
So it’s like when everyone believes something is valuable, but it’s not really?

Dra. Rowe:
Exactly. The key point is that market bubbles are fueled by collective belief, not real economic value. They're like illusions of wealth—until reality hits.

Michelle:
What are some real-world examples?

Dra. Rowe:
Let’s list a few:

• Tulip Mania (1600s): Tulip bulbs were selling for more than a house.

• Dot-com Bubble (late 1990s): Internet company stocks soared, then collapsed.

• Housing Bubble (2000s): U.S. home prices skyrocketed, then fell, triggering the 2008 financial crisis.

Lynn:
But how does that affect us now?

Dra. Rowe:
Good question. Here are three reasons why you should care, even as students:

1. Student Debt & Investment Risks: If you invest in a bubble—cryptocurrency or a hot stock—you could lose money quickly.

2. Job Market: When bubbles burst, companies cut jobs. You could graduate into a weak economy.

3. Cost of Living: Bubbles in housing or energy can make rent or daily expenses unpredictable.

Nilza:
So, how do we spot a bubble?

Dra. Rowe (writes on the board):
Three warning signs:

1. Prices rise faster than earnings or utility

2. Lots of “fear of missing out” (FOMO) behavior

3. People say, “This time is different.”

Michelle:
That sounds like some of the hype around NFTs or certain AI stocks.

Dr. Rowe:
Exactly. Not all hype equals a bubble, but extreme, unjustified optimism can be a warning.

Lynn:
So, should we stay away from all investments?

Dra. Rowe:
Not at all. The lesson is to understand value vs. speculation. Learn the fundamentals before investing. Markets can be powerful wealth builders—but only if you know the risks, like bubbles.

Nilza (nodding):
So basically, don’t get caught chasing imaginary value.

Dra. Rowe:
Well said, Nilza. And that’s your takeaway for today: In economics, always ask what’s driving the price. Because when a bubble bursts, gravity always wins.

Note: This is a classroom simulation script designed for first-year economics students. It illustrates the concept of a market bubble using simple analogies and interactive dialogue between a professor and the students. The script is adaptable for lectures, role-plays, or videos.
