The Impact of AI-generated Review Summaries: Evidence From Indian E-Commerce

Economics Department, University Of Arizona, Tucson AZ

The rise of AI-generated overviews is transforming how consumers interact with information in digital markets. These overviews, powered by the development of large language models (LLMs), condense vast volumes of information into accessible narratives, potentially mitigating the effects of information overload and providing better insights into product characteristics. In this research, I focus on AI overviews of product reviews on e-commerce platforms and investigate whether they influence consumer purchasing decisions by affecting product-level sales and pricing. Leveraging variation in the adoption of these overviews across the two largest e-commerce platforms in India- Amazon and Flipkart- I apply a difference-in-differences framework, with three-way fixed effects, to isolate the effect of AI summaries. I aim to provide new, and among one of the first, to my knowledge, evidence on the role of algorithmic information processing and presentation of consumer reviews in shaping consumer behavior, market outcomes, and platform competition in digital markets.

Empirical evidence for the availability heuristic causing an erroneous meta-cognitive judgment of one's objective financial knowledge. The reasons for disparities in financial knowledge are often explored through the lens of policy action and education. However, in this research, we study the role of cognitive bias in financial knowledge to explain disparities in perceived and Actual Financial Knowledge. We propose a model of overconfidence and then attempt to estimate how variance in levels of overconfidence can be explained specifically through the lens of exposures to financial shocks. Our analysis finds gender and educational differences in levels of financial overconfidence and finds empirical evidence that higher exposure to negative financial shocks predicts lower levels of overconfidence.
