My research efforts aim to apply theories and methods from economics and econometrics to interesting marketing problems. My early work investigates how grocers’ product assortment from multiple product categories in a common retail space influences consumers’ purchase decisions. The article has been published in Journal of Marketing and featured as “Journal Selection” by Marketing Science Institute in 2017.

My research domain has since been expanded to investigate; 1) firm’s product assortment decision as a response to a government intervention (e.g., taxation), 2) market competition in quality of products and services, and 3) a more complex set of supply and demand outcomes in a context of two-sided market. The empirical study of competition in product quality is particularly challenging as there is little reliable data available. To overcome this, my recent study extracts previously non-available information from various text data (e.g., online customer reviews) using latest text analysis methods.

Empirical contexts of my studies include students' choice over higher education, competition in fast-food industry, and the impact of policy shocks on the alcoholic beverage markets and on the two-sided markets such as crowdfunding platforms.
