My research is empirical and mainly about pricing and anti-competitive behavior. I use data from a price comparison website to study online retailers pricing stratgies in several regards. For example, I find that prices increase when the competing retailers meet in multiple markets. This shows that multimarket contact relaxes competition and facilitates tacit collusion.
In a different study I investigate how music distractions drive consumer choice in a field experiment in fast-food restaurants. We find that distracted consumers buy less. In another study I test if schools are more likely to grade leniently when competition is fiercer.
