The Economics of Love

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
