In a new working paper, Tuck professor Laurens Debo, together with Ran I. Snitkovsky of Coller School of Management, Tel Aviv University, tackle the tipping conundrum from an analytical point of view. The paper, “A modeling framework for tipping in the presence of a social norm,” details a mathematical model that can help explain why people tip and why, perhaps, tipping isn’t the most efficient way to pay servers for their work.
