Learning Equilibrium Mean-Variance Strategy
Dai, Min; Dong, Yuchao; Jia, Yanwei - 2021
We study a dynamic mean-variance portfolio optimization problem under the reinforcement learning framework, where an entropy regularizer is introduced to induce exploration. Due to the time-inconsistency involved in a mean-variance criterion, we aim to learn an equilibrium strategy. Under an...

Will investors adapt their investment behavior whenfaced with a change in information feedback and investmentflexibility?
Zeisberger, Stefan; Langer, Thomas; Weber, Martin - Institut für Schweizerisches Bankwesen <Zürich> - 2011
Assuming investors are loss averse, repeated risky investments are less attractive inmyopic evaluation. A theoretical foundation for this effect is given by the behavioralconcept of myopic loss aversion (MLA). The consequences of MLA have been confirmedin several between-subject experimental...

Optimal Trade Sizing in a Game with Favourable Odds : The Stock Market
Haghani, Victor - 2016
In this short note, we show investors one way to calculate ideal investment sizing by using two rules of thumb based on a simple outline of individual risk aversion. We illustrate these two heuristics, which are not widely appreciated, with thought experiments involving coin flips and ketchup &...

Time-Inconsistent Stochastic Linear–Quadratic Control : Characterization and Uniqueness of Equilibrium
Hu, Ying - 2015
In this paper, we continue our study on a general time-inconsistent stochastic linear-quadratic (LQ) control problem originally formulated in Hu, Jin and Zhou (2012). We derive a necessary and sufficient condition for equilibrium controls via a flow of forward-backward stochastic differential...

Strategically biased learning in market interactions
Bottazzi, Giulio; Giachini, Daniele - 2022
We consider a market economy where two rational agents are able to learn the distribution of future events. In this context, we study whether moving away from the standard Bayesian belief updating, in the sense of under-reaction to some degree to new information, may be strategically convenient...
