The Economics of Doing What You Love
Marketplace, the economics program on American Public Media, is running a fun series this week — asking economists to reflect on how thinking like an economist can shape your personal decisions. While the pieces are pretty light, it’s also a neat opportunity to teach some simple economics. Yesterday, it was my turn, and so I focused my economic lens on my marathon training. And thinking like an economist means thinking in terms of opportunity cost.
When I analyze the opportunity cost of running, it turns out to be surprisingly expensive:
As I spend my hours slugging out the miles, I’m forced to confront my choices. Instead of sweating it out on the trails, I could take on extra teaching and earn a few extra bucks. And so going running costs me good money. By my calculations, my 16-week training program comes at an opportunity cost of several thousand dollars. A quicker runner would have a smaller opportunity cost. It’s only because I’m both slow and an economist that I fret that the world’s cheapest sport is actually incredibly expensive.
But despite this cost, running is still worth it. Why? There are many other choices that non-economists make that come with an even worse cost-benefit ratio. The true advantage of thinking like an economist is that it can help you make better decisions:
To an economist, the choice is still a no-brainer. We think you should only do what you love, and pay for it by doing what you are good at.
By sticking to economics, I make time for running. Rather than spend hundreds of dollars worth of time cleaning my house each Sunday, I hire a cleaner who does a better job at a better price. When a friend asks me to help them move, I write them a check to pay professional movers instead. It’s just more efficient. And while it can be hard to forgo extra income for a long run, it is even harder to justify wasting that time on Facebook. And with the time that saves, I’m pulling on my shoes to head out for another run.
