We study the effect of ambiguity on the formation of bubbles and on the occurrence of crashes in experimental asset markets à la Smith, Suchanek, and Williams (1988). We extend their framework to an environment where the fundamental value of the asset is ambiguous. We show that, when the...

By now there are hundreds of scientific articles on experimental asset markets. Almost all of these experiments use a short and definite horizon. This may be one of the starkest differences to financial asset markets outside the laboratory, which usually have indefinite and comparatively long...

Maximizing output without taking into consideration the negative externalities generated, including the harm to the mental and physical health of the population creates psychological stress. Focusing on the bellwether indicators of economic performance including working more, generating income,...

This paper investigates the role, if any, played by the social media platform Reddit, in the events around the GameStop short squeeze in early 2021. In particular, we analyse the impact of discussions on the r/WallStreetBets subreddit on the price dynamics of the American online retailer...

Eye tracking can facilitate understanding irrational decision-making in contexts such as financial risk-taking. For this purpose, we develop an experimental framework in which participants trade a risky asset in a simulated bubble market to maximize individual returns while their eye movements...

This study proposes a rational expectation equilibrium model of crashes in an economy with information asymmetry and loss averse speculators. We obtain a state-dependent linear optimal trading strategy, which makes the equilibrium price tractable for the first time in such an economy. The model...

We study the Chinese government's stock market bailout operation in 2015. We focus on the bailout's opaque nature and explore its unintended consequences in both asset prices and investor behavior. We find that: (1) the market overreacts to the bailout news under partial information, which leads...

The systemic risk induced by a connection among financial objects is generally measured by returns, volatility, interbank loans, etc. Nevertheless, these measures do not capture the microscale component of the interconnections induced by heterogeneous investor activity. In this paper, we exploit...

We develop an experimental production economy to study the general equilibrium and welfare effects of speculation and stabilization policies. Participants playing the role of household-investors interact in labor, output, and, in some treatments, asset markets. Without the ability to trade...
