This paper investigates whether central banks can attenuate excessive mispricing in stocks as suggested by the proponents of a \leaning against the wind" (LATW) monetary policy. For this, we decompose stock prices into a fundamental component, a risk premium, and a mispricing component. We argue...

We develop a novel financial market model in which the stock markets of two countries are linked via and with the foreign exchange market. To be precise, there are domestic and foreign speculators in each of the two stock markets which rely either on linear technical or linear fundamental...

There has been a long debate about whether speculators are stabilizing or not. We consider a model where speculators have a stabilizing role in normal times, but may also provoke large risk panics. The very feature that makes arbitrageurs liquidity providers in normal times, namely their...

We develop a financial market model focused on fund managers who continuously adjust their exposure to risk in response to the payoff gradient. The base model has a stable equilibrium with classic properties. However, bubbles and crashes occur in extended models incorporating an endogenous...

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...

In this paper we introduce a calibration procedure suitable for the validation of agent based models. Starting from the well-known financial model of Brock and Hommes 1998, we show how an appro- priate calibration technique makes the model able to describe price time series.The calibration...

Lack of transparency in securitization transactions significantly contributed to thesevere financial crisis of 2007–2009. To increase transparency we—based on arecent idea by Markowitz (2009)—propose an incentive compatible mechanismfor future securitization transactions: financial claims...

Within this study we propose different measures to prove the influence of prior retail fund performance on fund flows. In contrast to previous literature, our work indicates that investors behave directly and in a selective manner by redeeming their shares of poor performing funds. By using a...

Lack of transparency in securitization transactions significantly contributed to the severe financial crisis of 20072009. To increase transparency we propose a new mechanism: financial claims with fingerprints. They would allow market participants at each stage of the securitization process to...
