When do consumers buy medications that reduce their chances of illness? Do charitable donors give more to anti-malaria charities that can provide bed nets at lower costs, or could they actually give less? Why are consumers more sensitive to discounts off of lower prices? Does a sales price feel lower relative to a single high list price or a range of high list prices?
These are some of the questions that I aim to address in my research on how cognitive biases affect consumer behavior and consumer judgments. A list of my papers is below, and you can read more about my projects here. My CV is available here. You can email me at: [email protected]. |
