Working Papers

[New Version] Eliciting Stopping Times (with Sebastian Ebert) [SSRN]

AbstractWe study how individuals plan dynamic risk-taking by eliciting stopping times—complete contingent plans of when to continue or stop taking a given risk. Despite substantial heterogeneity in stopping times, a machine-learning algorithm identifies a small number of economically meaningful strategy clusters. Many subjects use path-dependent and randomized rules, and trailing stop-loss strategies are more common than threshold strategies. Most subjects plan using forward rather than the normatively appropriate backward induction. Comparing planned stopping times with sequential risk-taking, we decompose dynamic inconsistency into the effects of memory constraints, defaults, mechanical inconsistencies induced by planning constraints, and planning as such.

We provide an overview video of the experimental design and videos of all experimental studies. An interactive tourist version of the experiment is available here.


Investor Beliefs and Asset Prices Under Selective Memory [Paper | SSRN]

  • Awards: Brattle Group PhD Candidate Award for Outstanding Research, 2024 WFA Conference
AbstractI present a consumption-based asset pricing model in which the representative agent selectively recalls past fundamentals that resemble current fundamentals and updates beliefs as if the recalled observations are all that occurred. This similarity-weighted selective memory jointly explains important facts about belief formation, survey data, and realized asset prices. Subjective expectations overreact and are procyclical, the subjective volatility is countercyclical, and the subjective risk premium has a low volatility. In contrast, realized returns are predictably countercyclical, highly volatile, and unrelated to variation of objective risk measures. My results suggest that human memory can simultaneously account for individual-level data and aggregate asset pricing facts.


Learning and Strategic Trading in ETF Markets [Paper]

AbstractDesignated broker-dealers arbitrage away differences between the market price of an ETF and the net asset value of the underlying assets. Using a dynamic strategic trading model, I show that this arbitrage mechanism increases long-term price informativeness but reduces short-term price informativeness. The information contained in the ETF price leads to additional learning, which improves long-term price informativeness. However, traders informed about the value of an underlying asset use their informational advantage to forecast arbitrage-induced price changes of all other assets contained in the ETF. The predictability of future price changes induces speculative cross-asset trading, which reduces short-term price informativeness. Thus, regulation targeting ETFs must balance short- and long-term price informativeness.
