Here's what caught my eye in research over the past week:
- Anderson et al. (with ungated earlier version here) look at whether the world’s best tennis pros play Nash equilibrium mixed strategies, finding that for most elite pro servers, a best-response strategy significantly increases their win probability relative to the mixed strategies they actually use
- Aucejo and Wong conducted a randomized controlled trial involving approximately 3,000 students across 39 introductory economics classes at Arizona State University, and find that personalised feedback messages that were tailored using information from students’ initial academic performance and surveys completed at the beginning of the semester benefit first-generation students in synchronous classes significantly, while no such effects are observed in asynchronous classes
- Roupakias and Chletsos (open access) find that the proportion of immigrants in a country is positively associated with the country's 'economic fitness', as measured by the World Bank's Economic Fitness index
- Cawley et al. (with ungated earlier version here) investigate whether the Jared Fogle scandal in 2015 had any effect on patronage at Subway restaurants, and find no significant effect
- Mohammed assesses the impact of Airbnb’s website redesign policy, which delayed the exposure of host profile photos, on racial discrimination, and finds a negligible reduction
