The Unexpected Impacts of Innovation
Prof. Judith Chevalier’s research has unraveled implicit incentives driving risk taking by mutual fund managers, the ways online reviews shift business strategy and consumer decisions, and the consequences of nursing home workers’ movement between facilities in spreading COVID-19.
To Extend Vaccines’ Reach, Distribute Them through Dollar Stores
A new Yale study says that a partnership with the Dollar General retail chain, which is being considered by the CDC, could bring vaccination sites substantially closer to low-income, Black, and Hispanic households in many parts of the United States.
Smartphone Data Shows How Shared Staff Spread COVID-19 through Nursing Homes
COVID-19 infections have spread rapidly through nursing homes. A new study co-authored by Yale SOM’s Judith A. Chevalier finds one likely explanation: staff members who work at multiple nursing homes.
Time to Put on a Mask
A team of Yale researchers says we should all be wearing cloth masks, but give the surgical masks to healthcare workers.
Gig Workers Value their Flexibility... a Lot
Using extensive data on Uber drivers, Yale SOM’s Judith Chevalier and her co-authors examined their driving patterns to understand the economic value of flexible scheduling. They found that rideshare drivers would have to earn as much as double to accept less-flexible arrangements.
Can Online Reviews Be Trusted?
The online, user-generated review is a boon for consumers—a chance to sidestep promotional claims and get an honest assessment. But as soon as reviews appeared online, fake reviews followed. A study co-authored by Professor Judith Chevalier looks at the prevalence of fake hotel reviews and tests a hypothesis about who might post them and why.
Are we good at making choices?
Do the choices we make as consumers serve our economic interests? Do they even reflect our real preferences? Three Yale scholars discuss research — their own and others' — that sheds light on these questions.
