We find that the CAPM fails to explain the small firm effect even if its non-parametric form is used which allows time-varying risk and non-linearity in the pricing function. Furthermore, the linearity of the CAPM can be rejected, thus the widely used risk and performance measures, the beta and...

This paper provides a theoretical explanation for the heteroscedasticity of asset returns. In line with existing empirical results, our model yields an asymmetric relationship between stock return and volatility. Based on the simple assumptions that investors behave according to Prospect Theory...

This paper discusses a novel explanation for asymmetric volatility based on the anchoring behavioral pattern. Anchoring as a heuristic bias causes investors focusing on recent price changes and price levels, which two lead to a belief in continuing trend and mean-reversion respectively. The...

This paper discusses an empirical analysis of the Expected Downside Risk (EDR) based asset-pricing model on Central and Eastern European and Developed Western European markets. The investigated risk measure applies a nonparametric approach that allows getting rid of any assumption on the...

We introduce an equilibrium asset pricing model, which we build on the relationship between a novel risk measure, the Expected Downside Risk (EDR) and the expected return. On the one hand, our proposed risk measure uses a nonparametric approach that allows us to get rid of any assumption on the...

We implement a market microstructure model including informed, uninformed and heuristic- driven investors, which latter behave in line with loss-aversion and mental accounting. We show that the probability of informed trading (PIN) varies significantly during 2008. In contrast, the probability...

We investigate multi-period investments where the initial capital and its gains are reinvested after each trading period. We point out that holding higher return investments even in the long run can be disadvantageous since, if the mean of a risky investment does not exceed the variance...

In the paper we introduce an empirical approximation of the log-optimal investment strategy that guarantees an almost optimal growth rate of investments. The proposed strategy also considers the effects of portfolio rearrangement costs on growth optimality and advises a suboptimal portfolio for...

We analyze the prices of Baedeker guidebooks issued between 1828 and 1945 in the English, French and German languages. We compile a repeat sales regression index of eBay hammer prices, which reveals a common factor in Baedeker guidebook prices. We find mixed evidence on the underperformance of...
