Research

I am broadly interested in understanding how consumers and organizations (businesses or government) interact in new technology mediated environment. My research inquiries fall under three areas.

Multichannel customer behavior

The rapid growth in new technology enabled channels (such as telephone, web, and mobile based channels), offers firms tremendous opportunities to connect with its customers. However, availability of multiple channels has made customers omnichannel (customers use multiple channels to complete their interaction with the firm), and thus made management of its multichannel operations extremely challenging. In my research, I have conducted several field studies to answer questions, such as: How customers fulfill different needs at different stages (pre-sales, sales, and post-sales) of their interaction via different channels of the firm? How do customers’ needs vary with the types of products/services (such as higher need of physical evaluation for high-touch products)? How capabilities of different channels are better suited for fulfilling specific needs of customers?

Online product recommendation network

Recommendation engines are extensively used to hyperlink related products on the focal products’ pages. Such hyperlinking of related products’ pages results in a network of interconnected products – called product recommendations network – on the websites. How do these networks create economic value? Do these network help users learn the interrelationship between products or they simply provide higher exposure to products? Through these mechanisms, the recommendation networks can reduce users’ search costs and thus increase their demands on the website. However, measuring the causal value of recommendation networks is challenging because such networks are endogenously formed based on product sales/popularity. In my research, I examine the underlying mechanisms through which recommendation networks create economic value and estimate its causal value in different field settings.

Societal Impact of IT

Different functionalities of information technology has the potential to augment and/or substitute for traditional inputs in meeting societal needs. For instance, IT enabled personalization can augment the educational infrastructure to improve the delivery of education in resource constraint educational system in developing countries. I have conducted a field study to examine how computer generated adaptive homework can improve learning among students in resource constrained schools in India.
