具有短期资产的连续时间资产市场博弈

A continuous-time asset market game with short-lived assets

Mikhail Zhitlukhin

摘要:

本文考虑了一个具有短期资产和内生资产价格的投资市场的连续时间博弈模型。本文的第一个目标是建立一个决定投资者财富过程的随机方程,并给出其解存在的条件。第二个目标是证明存在一个策略,使得使用该策略的投资者的相对财富的对数是下鞅,而与其他投资者的策略无关,并且任何其他本质上不同的策略的相对财富渐近为零。该策略在模型中可视为最优增长型投资组合。

英文摘要:

We consider a continuous-time game-theoretic model of an investment market with short-lived assets and endogenous asset prices. The first goal of the paper is to formulate a stochastic equation which determines wealth processes of investors and to provide conditions for the existence of its solution. The second goal is to show that there exists a strategy such that the logarithm of the relative wealth of an investor who uses it is a submartingale regardless of the strategies of the other investors, and the relative wealth of any other essentially different strategy vanishes asymptotically. This strategy can be considered as an optimal growth portfolio in the model.
