Speed traps: algorithmic trader performance under alternative market balances and structures (2023)
Journal Article

Using double auction market experiments with both human and agent traders, we demonstrate that agent traders prioritising low latency often generate, sometimes perversely so, diminished earnings in a variety of market structures and configurations. W... Read More about Speed traps: algorithmic trader performance under alternative market balances and structures.

On the generalizability of using mobile devices to conduct economic experiments (2023)
Journal Article
Guo, Y., Shachat, J., Walker, M. J., & Wei, L. (2023). On the generalizability of using mobile devices to conduct economic experiments. Journal of Behavioral and Experimental Economics, 106, Article 102057. https://doi.org/10.1016/j.socec.2023.102057

Mobile devices enable experimental economists to collect decision-making data from more heterogeneous samples, thereby increasing the generalizability of their results. This generalizability may be compromised if the device is a relevant behavioural... Read More about On the generalizability of using mobile devices to conduct economic experiments.

A test of the Modigliani-Miller theorem, dividend policy and algorithmic arbitrage in experimental asset markets (2023)

We demonstrate when market experience is spaced out over a longer period of time (weeks instead of minutes), the increase in pricing efficiency is very small - if at all - for the same population of traders. However pricing efficiency gains are subst... Read More about Are you experienced? How the time spacing of traders' market experience impacts bubble formation in experimental asset markets.
