Jack Stafford - The Economics of Love Lyrics

I've done a differential game model
On our partnership
the results are what you'd expect

Based on effort and appeal
Our love it is ideal
Cos we've both so heavily invested

But it's not the sunk cost fallacy
That keeps us together
It's the ongoing returns
And compounded interest

Not the sunk cost fallacy
Why we go on forever
It's a high-yield bond
vs a high-heeled blonde
I've learnt the economics of love

It's growing exponentially
A concave curve
Building on our saving reserve

With no signs of fragility
And maximized utility
Returns are much greater than cost

But it's not the sunk cost fallacy
That keeps us together
It's the ongoing returns
And compounded interest

Not the sunk cost fallacy
Why we go on forever
It's a high-yield bond
vs a high-heeled blonde
I've learnt the economics of love

The coefficient of variation
Of our love affair
Shows mutual benefits
Of which we're both aware

Perceived costs are low
Cost of separation is high
Net benefit's optimized

But it's not the sunk cost fallacy
That keeps us together
It's the ongoing returns
And compounded interest

Not the sunk cost fallacy
Why we go on forever
It's a high-yield bond
vs a high-heeled blonde
I've learnt the economics of love
