A Year of Collaboration: MobLab in Kellogg School of Management

“Welcome,” beckons Donald Dale, waving me into his classroom. “It’s so good to see you.” We continue to exchange cheerful greetings. It’s been a year since the Kellogg School of Management at Northwestern University adopted MobLab. We’ve been working closely with Donald and other professors at Kellogg during the adoption to integrate MobLab and create […]

How Can We Tell a Norm is Strong?

Norms or informal rules and expectations are all around us. Most of the time we don’t notice them until someone has violated them. For example, last year when I entered the bathroom I walked in and saw a long row of empty urinals. Suppose there were seven. I chose the center with three empty on […]

Classic examples include radio signals, national defense, ideas, and fireworks to name a few. In 1919, […]

Feynman's swinging pendulum and how it relates to Moblab's Competitive Market game

Borrowing from Feynman: How Teaching Competitive Market Theory Can Become a Performance Art

Nobel Laureate Richard Feynman is one of the most celebrated scientists of the 20th century. In the 1960’s, before he launched into discussions of mechanics, waves, or properties of heat and matter, he did a spectacular pendulum demonstration. I remember hearing as an undergraduate about this Feynman story and was impressed by the bravado and […]

Jury Voting In-Class example

One interesting result that I always enjoy teaching in my game theory class is Feddersen and Pesendorfer’s “Convicting the Innocent: The Inferiority of Unanimous Jury Verdicts under Strategic Voting.” Their result suggests that if jurors vote strategically, then requiring unanimity to convict may actually lead to more incorrect convictions. While this result is fairly unintuitive […]
