Doctoral Dissertation Research in Economics: The Social Dimension of Quality

Why do consumers willingly pay more for brand name products compared to non-branded products even though the two have the same attributes.

The researchers will collect data on a number imported and domestically produced consumer goods to test this theory.

Factor Based Imputation of Missing Data

Missing observations occur in physical and social science research; Missing observations may arise from people not responding to question,; changes in data definitions, technology of data collection, and natural disasters and wars, among others.

Though they work well in practice, the theoretical properties of the imputed data are not well understood.

Interventions on Diffusion Processes

This award funds research in economic theory. The project seeks to improve our understanding of how social networks shape the spread of opinions, products, and ideas. The core objective is to turn insights from theoretical models into practical guidance on how to conduct targeted seeding, how to design regulations for social media, and how to advertise new products with uncertain quality. The award funds three projects. The first project will develop a framework to study how best to target individuals based on their network positions in order to spread a new idea or innovation.
