The most important single observation from this research is the similarity between our wide range of results and the multitude of seemingly divergent conclusions about free riding from previous experimental results. Even when defined in the restrictive manner of this paper, free riding is...

The causal impact of algorithmic trading on market quality has been difficult to establish due to endogeneity bias. We address this problem by using the introduction of co-location, an exogenous event after which algorithmic trading is known to increase. Matching procedures are used to identify...
