Experimental Design

Experimental Design
The experimental design follows the bubble game experiment by Caginalp et al. (2001) and Andrade et al. (2016).
Experimental Design Details
With the help of this randomized controlled experiment, we intend to investigate the influence of social interactions on asset markets. The study will provide an empirical test of the hypothesis that social interactions increase asset price bubbles. The experimental design follows the bubble game experiment by Caginalp et al. (2001) and Andrade et al. (2016) with a critical variation: Different from Andrade et al. (2016) the treatment condition will not make use of videos shown to investors, but instead allow investors within the market to interact with each other using typical social media features such as likes. Thus, while the control condition replicates the standard bubble game by Caginalp et al. (2001), the treatment condition additionally allows participants to like the trades of their peers with typical social media features.
