Поднимаются проблемы применимости кумулятивной теории перспектив Канемана-Тверски к выбору инвестиционного портфеля в условиях иррациональности инвесторов. Предлагается подход, основанный на методе надежного принятия решений, который мог бы объяснить S-образность функции искажения вероятности. В заключение рассматриваются различные потенциальные исследовательские вопросы, связанные с применимостью подходов теории принятия решений к выбору инвестиционных портфелей.</p></abstract><trans-abstract xml:lang="en"><p>We analyze and discuss the standard portfolio approach in light of recent development in decision theory and behavioral economics. We point out problems when applying Kahneman-Tversky cumulative prospect theory to portfolio choice namely irrationality of investors. We suggest a framework based on robust decision making that might explain S-shaped probability weighting. We conclude by suggesting different future research questions to apply empirically relevant decision-theoretic approaches to portfolio choice.</p></trans-abstract><trans-abstract xml:lang="en&lt;p&gt;We analyze and discuss the standard portfolio approach in light of recent development in decision theory and behavioral economics.
