Precommitted Investment Strategy versus Time-Consistent Investment Strategy for a Dual Risk Model

Time-consistent investment strategy under partial information ¬リニ

This paper considers a mean–variance portfolio selection problem under partial information, that is, the investor can observe the risky asset price with random drift which is not directly observable in financial markets. Since the dynamic mean–variance portfolio selection problem is time inconsistent, to seek the time-consistent investment strategy, the optimization problem is formulated and ta...

Time-consistent reinsurance–investment strategy for a mean–variance insurer under stochastic interest rate model and inflation risk

In this paper, we consider the time-consistent reinsurance–investment strategy under themean–variance criterion for an insurer whose surplus process is described by a Brownian motion with drift. The insurer can transfer part of the risk to a reinsurer via proportional reinsurance or acquire newbusiness.Moreover, stochastic interest rate and inflation risks are taken into account. To reduce the ...

a paradigm shift away from method-wise teaching to strategy-wise teaching: an investigation of reconstructive strategy versus communicative strategy

Exploring Investment Strategies in Financial Markets through Agent-based Modeling: Active Investment Strategy and Passive Investment Strategy Exploring Investment Strategies in Financial Markets through Agent-based Modeling: Active Investment Strategy and Passive Investment Strategy

Recent progress of computer technology makes it possible to analyze financial and economic systems through simulation studies. Among them, agent-based modeling is promising. In this paper, using agentbased modeling from distributed artificial intelligence, I discuss the validity of passive investment strategies in financial markets where active investors who hold future information exist. As a ...
