ECONOMICS OF EVERYDAY LIFE
What economics can teach us about the choices we make, the value we assign, and the lives we build.
Externalities: Your Choices Don't Stop With You
We like to think of our decisions as belonging to us.
My money.
My business.
My time.
My decision.
My choice.
And technically, they may be.
But that doesn’t mean the consequences stop with us.
Economics has a concept for what happens when the actions of one person affect others who aren’t directly involved in the transaction:
Externalities.
An externality is a cost or benefit created by an activity that affects a third party who wasn’t part of the original decision.
The classic example is pollution.
A factory produces something valuable and makes money.
The people buying the product benefit.
But if the factory pollutes the surrounding environment, people living nearby may bear some of the cost.
They didn’t buy the product.
They didn’t make the decision.
But they experience part of its consequences.
The transaction may be private. The impact isn’t.
And suddenly, economics becomes rather interested in responsibility.
Not every consequence appears on the receipt.
This is what makes externalities so interesting.
When we make a decision, we naturally look at the costs and benefits that affect us.
What will I gain?
What will I have to pay?
What will this require from me?
But there may be other costs that don’t appear in our calculation because someone else absorbs them.
A business cuts costs.
The financial statements improve.
But perhaps employees absorb the cost through excessive workload.
A manager pushes a team to hit an unrealistic deadline.
The project succeeds.
But someone takes the stress home.
A company rewards aggressive sales.
Revenue increases.
And externalities aren’t always negative.
This matters too.
Some choices create benefits that extend beyond the person making the decision.
Education is a good example.
A person gains knowledge and skills, but society can also benefit when educated people contribute those skills to their communities, workplaces and families.
One person volunteering can benefit people they may never meet again.
A leader developing someone can create opportunities that extend far beyond the immediate working relationship.
A business that treats employees well may create benefits that reach families and communities.
A small act of generosity can travel further than we ever see.
These are positive externalities.
Our actions can create value beyond the person who initiated them.
Which means our impact is bigger than our intention.
Here’s an uncomfortable truth:
We tend to judge ourselves by what we meant to do.
Other people experience what actually happened.
We might say:
“I didn’t mean to put pressure on them.”
“I was only trying to get the work done.”
“I didn’t realise it would affect them.”
And perhaps we genuinely didn’t.
But lack of intention doesn’t erase consequence.
At the same time, consequence doesn’t automatically prove bad intent.
Both things can be true.
You can mean well and still create harm.
And you can create a benefit without ever intending to.
This is why responsibility is more complicated than intention.
Leadership makes this impossible to ignore.
The higher our influence, the more people can be affected by our decisions.
A leader’s decision doesn’t stay neatly inside the meeting room.
A change in direction affects a team.
A communication style affects psychological safety.
A promotion decision affects morale.
A restructuring decision affects families.
A leader’s behaviour becomes part of the environment other people have to work in.
That doesn’t mean leaders must carry responsibility for every consequence of every decision.
That would be impossible.
It means they should become increasingly aware that their decisions have a radius.
The question isn’t only:
“Does this decision work for me?”
It is also:
“Who else will experience the consequences of this decision?”
This is where responsibility becomes more interesting than blame.
We often want to know:
Whose fault is it?
Externalities invite a different question:
Who bears the cost?
Those aren’t always the same person.
Some responsible questions we can ask before making a significant decision:
Who benefits?
Who pays?
Who carries the risk?
Who absorbs the inconvenience?
Who isn’t in the room?
Because sometimes the person making the decision isn’t the person who pays its real cost.
But there is a trap here too.
If we become too concerned about every possible consequence, we could become paralysed.
Every decision affects someone somehow.
You cannot live without creating ripple effects.
Choosing one employee for a promotion means another person doesn’t get it.
Starting a business changes something in a market.
Leaving a job affects colleagues.
Saying no affects someone who wanted a yes.
Even choosing to rest may mean something else doesn’t get done.
Impact is inevitable.
Responsibility is about what we do with that knowledge.
We cannot eliminate every externality.
But we can become more conscious of them.
We can ask better questions.
We can listen to people who experience the consequences differently from us.
We can mitigate harm where reasonably possible.
And sometimes, we can redesign the decision itself.
This is what intentional leadership really requires.
Not predicting every consequence.
Not pleasing everyone.
Not avoiding difficult decisions.
But developing the habit of looking beyond the immediate transaction.
Beyond:
What do I get?
Beyond:
What does this cost me?
Toward:
What else does this create?
Because every decision sends something into the world.
A behaviour.
A message.
A precedent.
A cost.
A benefit.
A consequence.
Sometimes we see it.
Sometimes we don’t.
Sometimes we benefit from it.
Sometimes someone else does.
And sometimes someone else pays for it.
So go beyond asking:
“What do I want to happen?”
To:
“What happens because of what I choose?”
That is a harder question.
It is also a more responsible one.
Because your choices may belong to you.
Their consequences don’t always do.
