套利定价模型中效用最大化者的最优策略

On optimal strategies for utility maximizers in the Arbitrage Pricing Model

Miklos Rasonyi

摘要:

我们考虑一个流行的模型的微观经济学可数许多资产:套利定价模型。我们研究了在期望效用准则下的最优投资问题,并寻找保证最优策略存在的条件。以往的研究结果需要对资产收益率分布的尾部进行一定的限制性假设。使用不同的方法,我们设法消除这一假设,在资产回报率的时刻更强的假设的代价。

英文摘要:

We consider a popular model of microeconomics with countably many assets: the Arbitrage Pricing Model. We study the problem of optimal investment under an expected utility criterion and look for conditions ensuring the existence of optimal strategies. Previous results required a certain restrictive hypothesis on the tails of asset return distributions. Using a different method, we manage to remove this hypothesis, at the price of stronger assumptions on the moments of asset returns.
