This paper studies a class of robust mean-variance portfolio selection problems with state-dependent risk aversion. Model uncertainty, in the sense of considering alternative dominated models, is introduced to the problem to reflect the investor's ambiguity aversion. To characterize the robust...

The mutual fund industry consists of heterogeneous managers and investors. Hence, traditional models of delegated portfolio management need to be extended to allow heterogeneity. We propose that this extension can be modeled as a dual matching-contracting problem of endogenously repeated trust...

We consider multistage bidding models where two types of risky assets (shares) are traded between two agents that have different information on the liquidation prices of traded assets. These prices are random integer variables that are determined by the initial chance move according to a...

The significant excess of the price of risk, research question in the version paper, [S. Chule, in Applied Mathematical Finance, submitted June 2016], is space-domain form re-evaluated into the stochastic problem objective of the premium risk. The adapts of the conventional generic replication...

We study a continuous-time model of consumption and portfolio selection with the stochastic investment opportunity and the credit constraints endogenously determined in the business cycle modeled by the regime switch. By using the martingale approach and transformation into optimal stopping...

We study a continuous-time model of consumption and portfolio selection with limited commitment in a stochastic environment. The credit constraints of a household are determined endogenously in the credit market where creditors know that the household is not committed to payment of debt. By...

Portfolio selection simulator of social interaction is proposed in this paper. We explained why different investors possess different portfolios in time and why portfolios change with the change of the environment. The developments of the games are path-dependent depending on several factors....

Portfolio selection in this paper is done in an agent-based setting with individuals communicating through the social network. We explained why different individuals possess different portfolios in time and why portfolios change with the change of the environment. The developments of the games...
