Research
Our research is primarily focused on issues in Quantitative Marketing, Marketing Analytics, and Behavioral and Experimental Economics. In particular, our work centers on examining the behavior and decision-making of consumers and firms in the context of the digital economy.
Methodologically, our approach is strongly empirical, with a focus on experimental methods—including lab, web, and field experiments—as well as on the modeling of observational and survey data. We frequently collaborate with companies and with researchers from both national and international institutions. In interdisciplinary projects, we also work closely with experts in computer science, information systems, and psychology.
