Portrait of Dheer Avashia
Portfolio

Hello, I'm Dheer Avashia

I am currently a PhD student in Economics at the University of Arizona, applying Behavioral-Industrial Organizational perspectives and methods to study how AI shapes consumer behavior and markets.

When I am not fighting with myself over identification, I am probably trying out a new musical instrument or optimizing (some would say unnecessarily) the brewing process of my next cup of coffee.

Research

Free Information, Costly Search: AI Summaries, Consideration, And Verification

Third-Year Paper, University Of Arizona

Expand

This paper develops a demand-side model of search in which entering an option (product) reveals a free AI-generated compression of binary signals (reviews) and deeper individual inspection of those signals is costly. I embed a compression-based information structure into a dynamic search environment with both across-option consideration and within-option verification. I show analytically, for general signal-set sizes, that better underlying reviews lead to less review-reading when AI summaries are present: the verification threshold diverges as raw-signal precision approaches complete certainty, and the set of states in which costly inspection is optimal shrinks near perfect precision. The mechanism is that AI summaries compress the same evidence consumers would unpack at a cost, so improving raw-signal precision simultaneously strengthens the summary and devalues the underlying signals. By numerically solving the model with and without AI, I find that the costly search freed by AI-driven verification substitution can expand consideration sets, creating a reallocation from search depth to search breadth whose net effect on choice-quality outcomes is parameterdependent.

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

Second-Year Paper, University Of Arizona

Expand

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.

Modeling Financial Volatility with Multinomial Generalized Auto-Regressive Conditional Heteroskedasticity

Term Paper, University Of Arizona

Expand

Modeling the levels of volatility for a portfolio of assets has been imperative in analyzing individual financial decisions. In this paper, I explore models that allow for volatility clustering (ARCH and GARCH) and specifically look at a five-year dataset of the S&P 500 stocks to model the returns to a portfolio of assets using Multinomial GARCH (DCCM).

Financial Overconfidence and Shocks

Economics Honors Senior Thesis, University of The South

Expand

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.

The Theory of Huffman Encoding

Mathematics Senior Thesis, University of The South

Expand
  • In this project, I surveyed research in Algorithmic Information Theory. I understood the functions and mechanisms of Turing Machines, fundamental information theory concepts: Probability, Entropy, and Complexity. I then, specifically, focused on Huffman's Encoding Problem, analyzed proofs of optimal lossless encoding, theories of fundamental binary data encoding, and studied Huffman trees.

  • Surveyed experimental economics literature on price bubbles and crashes in spot asset markets.

Social Media and Orthrexia Nervosa Onset In College Students

Psychology Term Paper, University Of The South

Expand
  • Eating disorders are becoming highly prevalent in college students, as several studies have reported a greater presence of eating disorders on college campuses as compared to the general population (Fitzsimmons-Craft et al., 2019). Image expectations might help better understand the reasons for the onset of ON in college students. One such factor is Imaginary Audience. Imaginary Audience is a state in which individuals believe they are actively being judged by peers (Elkind & Bowen, 1979); it is one of the most frequent ideation states faced by adolescents (O'Connor, 1995). In this study, social media use is expected to predict levels of ON in college students, with Imaginary Audience as a potential mediating variable. Current literature search reveals sparse research on the connection between these two variables. This study uses an online survey to gather data about three constructs: the presence of an imaginary audience, social media use, and the prevalence of ON. The study predicts that a higher influence of social media and the prevalence of an imaginary audience will be positively associated with higher levels of ON in college students.
