Booms, busts and behavioural heterogeneity in stock prices
Hommes, Cars H.; Veld, Daan in't - 2015 - This draft: July 2015
We empirically evaluate a behavioural model with boundedly rational traders who disagree about the persistence of deviations from the fundamental stock price. Fundamentalist traders believe in mean-reversion, while chartists extrapolate trends. Agents gradually switch between the two rules,...

Capital structure arbitrage revisited
Wojtowicz, Marcin - 2014
We study risk and return properties of capital structure arbitrage strategies aiming to profit from temporal mispricing … between equity and credit default swaps (CDSs) of companies. We find that capital structure arbitrage provides an attractive … annualized return of 24.35% on invested capital. The arbitrage returns are higher for lower rated companies and surprisingly they …

Brock, William A.; Hommes, Cars H.; Wagener, Florian … - 2008
This paper formalizes the idea that more hedging instruments may destabilize markets when traders are heterogeneous and adapt their behavior according to experience based reinforcement learning. We investigate three different economic settings, a simple mean-variance asset pricing model, a...

Stoltenberg, Christian; Uhlendorff, Arne - 2023
In this paper, we document that households' consumption expenditures crucially depend on their expected earnings - even after controlling for realized earnings, wealth and time-invariant unobserved characteristics such as permanent income and over-confidence. To explain this evidence, we develop...

Stoltenberg, Christian; Uhlendorff, Arne - 2022
In this paper, we document that households' consumption expenditures depend on their expected earnings - even after controlling for realized earnings and wealth. To explain this evidence, we develop and structurally estimate a standard-incomplete markets model in which rational households...
