International Journal of Research in Marketing to publish study from assistant professor of marketing Sung Ha Jang
Kansas State University assistant professor of marketing Sung Ha Jang, along with co-authors Ashutosh Prasad and Brian Ratchford from the University of Texas at Dallas, recently had a paper accepted for publication in an upcoming edition of the International Journal of Research in Marketing.
The study, "Consumer Spending Patterns across Firms and Categories: Application to the Size and Share of Wallet," considers the problem of predicting consumer expenditures at competing firms when data is unavailable.
The paper contributes a methodological tool for more accurate prediction of size-of-wallet and share-of-wallet and better targeting of customers when expenditures at competing firms are unavailable. This is accomplished by considering consumer heterogeneity and asymmetric complementary and substitute interactions between expenditures.
