Research Goals

The primary goal of Dr. Jang's research is to examine underlying mechanisms of marketing phenomena and develop quantitative models applicable to general situations. Specifically, he is interested in consumers’ search behavior, purchase decisions, and firms’ advertising strategies in various areas. As some empirical models require novel estimation methods, Dr. Jang develops the Bayesian estimation method to quantify complicated decision processes.

  • Identifying how consumers’ risk taking attitude affects their financial product purchases
  • Investigating how a pseudo-product harm crisis affects firms’ advertising strategies and online consumer behaviors (utilizing a text mining technique)
  • Consulting: Preliminary consulting for H&R Block to make profit models and develop marketing plans, Marketing research consulting for local organizations (Greater Manhattan Community Foundation and Boys and Girls Club of Manhattan)
