Hello, I'm Dheer Avashia

This paper explores the economic trade-offs consumers make when faced with AI-generated review summaries. By building a demand-side model of search, I demonstrate a counterintuitive result: the better the underlying reviews (and therefore the AI summary), the less likely consumers are to actually read them. Because AI compresses the information consumers would otherwise spend time unpacking, it reduces the value of deep verification. However, this doesn't mean consumers search less overall. Instead, I find that AI frees up cognitive resources, allowing consumers to expand their consideration sets and browse a wider breadth of options. Finally, I extend this framework to multi-dimensional products, showing exactly how AI's impact depends on how well the summary matches the specific features a consumer values

This paper studies whether Amazon India's December 2023 rollout of AI-generated review summaries — which compress large review corpora into concise product signals — shifted equilibrium prices relative to Flipkart, a close competitor without an analogous feature. Using the first large-scale matched Amazon–Flipkart price panel (1,196 products, 86 months), I estimate a 2–4 log-point medium-run Amazon-relative price decline, triangulated across TWFE, BJS imputation, matrix completion, and interactive fixed effects. The analysis pairs this estimate with a full diagnostic stack — support-frontier audits, source-composition sensitivity, Rambachan–Roth partial identification, and randomization inference — to define precisely what the evidence can and cannot support. The result is interpreted through an evaluation-cost model in which AI summaries raise the residual demand elasticity facing sellers, with the strongest category-level corroboration in Toys & Games, where review narratives are most decision-relevant and third-platform entry exposure is lowest

Paper

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).

Paper

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.
