WORKING PAPERS


"Inattentive Retail Investors" Coming soon (with Fernando Chague and Rodrigo De-Losso)

We explore a tax-exemption discontinuity to identify inattentive investors among individuals who trade frequently. Inattentive investors are significantly more prone to several behavioral biases.


"Individuals Neglect the Informational Role of Prices: Evidence from the Stock Market" (with Fernando Chague and Rodrigo De-Losso)

Based on evidence from the lab, Eyster, Rabin, and Vayanos (2018) assume the existence of investors with "cursed beliefs" to explain the observed high levels of trading volume. Using field data, we show that these investors do exist.


"The Short-selling Skill of Institutions and Individuals: a Market-wide and Out-of-sample Analysis" (with Fernando Chague and Rodrigo De-Losso) - under revision

We show that some short-sellers - institutions and individuals - can beat the market. Robust out-of-sample evidence. We study how they trade.
