Private colleges that fret about affordability are increasingly turning to a new strategy: cutting sticker prices steeply while also trimming financial aid. So-called tuition resets are being deployed mostly at small institutions, both as a way to show that they’re responsive to market pressures and as a way to grab students’ attention. A new analysis by economist Lucie Lapovsky finds that tuition resets can actually boost enrollment if done carefully and deliberately -- and with enough time to develop an institutionwide plan.
