Last week I was able to meet Linda Ghent at the National Economics Teaching Association Conference in Austin, Tx. Little did I know that Linda was the author of one of my favorite economics sources: YadaYadaYadaEcon.com, which covers Seinfeld if you didn't catch the reference.

Diminishing Marginal Utility with Swiss Cake Rolls
This challenge would have definitely centered around Twinkies, had it not been for their bankruptcy and subsequent disappearance from shelves. Hopefully a deal can be reached to bring back the golden rolls of glory in time for this summer. Until then, Swiss Cake Rolls must suffice.
Early in every semester, I like to engage the class in a "real life" example of some type of economic phenomenon. Too often, instructors jump in with the dull routine of supply vs. demand, and efficiency vs. equity. Instead, I like to grab a few students, make them engulf 10 Swiss Cake Rolls (voluntarily of course), and then ask them how they feel. Luckily for the class, that concept won't be taught for a few weeks, but it at least gets them excited about economics.
For those unfamiliar with diminishing returns, as people employ additional units of inputs, their output increases at a decreasing rate. What does that have to do with Swiss Cake Rolls? Consider our hungry eaters as trying to maximize their utility (output) by consuming the delectable dessert (inputs). They were extremely happy with the first one, but the second one didn't bring them nearly as much satisfaction, nor did the subsequent desserts. On the consumer side, this is referred to as diminishing marginal utility. The video should help show the effects of diminishing returns. Thankfully no one had negative returns:
