11 Economic Laws That Reveal How We Think About Money

“We think we're being rational with money. But most of the time, we’re just being human.”

🧠 When More Becomes Less: 11 Economic Laws That Reveal How We Really Think

At The SIP Sage, I often say that investing is not just about markets — it’s about minds.

We’ve all heard of economic laws. But what many people don’t realise is:
👉 Some of the most important ones aren’t just mathematical — they’re deeply psychological.

They explain why we keep switching funds, why we chase performance, why we freeze in front of too many options — and why we so often regret financial decisions in hindsight.

Let’s explore 11 such economic ideas that don’t just define economies — they define us.


1. 🥐 Law of Diminishing Marginal Utility

"The first bite is heaven. The fifth is just food."

As we consume more of something, the satisfaction (or “utility”) we get from each extra unit keeps declining.

In real life:

  • The first ₹10,000 saved feels amazing.
  • The fifteenth policy? Exhausting.
  • The tenth mutual fund? Probably overlapping.

This law reminds us: More doesn’t always mean better.

2. ⚙️ Law of Diminishing Returns

"Working harder isn't always working smarter."

This applies when you keep increasing one input (like time, effort, or money) — but the output increases less and less, and may even drop.

Behavioural Trap: Most of us don’t know when to stop. We confuse effort with outcome.

3. 👜 Veblen Effect

"Pricey = Prestigious?"

Some goods become more desirable because they’re expensive — not in spite of it. It’s about status signaling.

In money terms: We often choose high-cost funds, ULIPs, or branded insurance thinking: “If it costs more, it must be better.” Spoiler: It’s rarely true.

4. 📉 Loss Aversion

"Losing ₹100 feels worse than gaining ₹100 feels good."

We’re wired to fear losses more than we enjoy gains. This is why many investors panic-sell in crashes and hesitate to book profits when markets rise.

5. 🧮 Mental Accounting

"Money has no labels — but we give it some."

We treat money differently based on its source or label:

  • Bonus? Splurge-worthy.
  • Salary? Sacred.
  • SIPs? Untouchable — until there’s a holiday offer.

Truth: Smart money doesn’t care where it came from. It just needs to be used well.

6. ⌛ Time Inconsistency

"Today always feels more important than tomorrow."

We often pick short-term pleasure over long-term gain — even when we know better.

Examples: Skipping SIPs, delaying term plans, buying gadgets first.

7. 🎭 Bandwagon Effect

"Everyone’s doing it, so it must be good."

We follow the crowd — especially in investing.

Behavioural Sign: Jumping into trending funds or sectors just because they’re popular on social media.

8. 🚫 Snob Effect

"Too common? I don’t want it."

The opposite of the bandwagon. Some avoid popular products just to feel unique.

Example: Avoiding PPF or index funds just because they seem too “basic”.

9. 🪙 Endowment Effect

"It’s mine, so it must be valuable."

We overvalue what we already own — even if it’s not performing.

Behavioural Sign: Holding dud stocks or legacy ULIPs because they’re “ours”.

10. 🕳️ Sunk Cost Fallacy

"I've already put so much into this — I can't quit now."

We irrationally continue with bad investments or decisions because we’ve already invested time or money.

Better approach: Ignore sunk costs. Look forward.

11. 🌀 Paradox of Choice

"Too many options = no decision."

More choices should lead to better decisions — but often lead to confusion, anxiety, or inaction.

In personal finance: Choosing from hundreds of funds or comparing too many insurance policies leads to analysis paralysis.


🎯 Final Thought

"Knowing these laws won’t make you perfect — but it will make you wiser."

Understanding how we really think about money gives us an edge — not just in investing, but in building a calm, consistent financial life.

At The SIP Sage, we believe that self-awareness is a financial asset.

So take a breath. Slow down. Know when “more” becomes “less”.
And always — invest like a human, not a machine.
