oTree: The bubble game

Bubbles and speculative behavior have been documented in real-world and experimental asset markets alike. Moinas and Pouget (2013) introduce the bubble game representing a sequential market with both bubble and no-bubble equilibria, in which speculative behavior can be analyzed using concepts from game theory. This article presents a ready-to-use software application for oTree (Chen et al., 2016) which allows to easily conduct the game in various settings within a modern web-programming framework. Researchers can adapt the game to their needs in a straightforward way by modifying thoroughly-documented variables in a single file. The software module supports responsive graphical designs and is prepared for multilingual use on any device with a web browser, allowing the implementation in the field, the laboratory, the classroom, or online.
