This contribution addresses the impact of high-frequency electronic liquidity provision strategies on financial markets' intraday dynamics, by evaluating the interaction between multiple trading strategies within a computer laboratory, i.e. an artificial stock market. Initially, a realistic...

We provide two novel dynamic double auction (DA) mechanisms for a class of economies and study their convergence property to competitive equilibrium. For DA mechanisms, we find a parameter on the two sequences of the marginal bid increments (bid step-size) and ask decrements (ask step-size) that...

Interconnectedness among insurers and reinsurers at a global level is not well understood and may pose a significant risk to the sector, with implications for the macroeconomy. Models of the complex interactions among reinsurers and with other participants in the financial system and the real...

We review heterogeneous agent-based models of financial stability and their application in stress tests. In contrast to the mainstream approach, which relies heavily on the rational expectations assumption and focuses on situations where it is possible to compute an equilibrium, this approach...

We introduce human traders into an agent based financial market simulation prone to bubbles and crashes. We find that human traders earn lower profits overall than do the simulated agents ("robots") but earn higher profits in the most crash-intensive periods. Inexperienced human traders tend to...

Liquidity provision through its repo auctions has been one of the main instruments of the European Central Bank (ECB) to address the recent tensions in financial markets since summer 2007. In this paper, we analyse banks’ bidding behaviour in the ECB’s main refinancing operations (MROs)...
