The purpose in this letter is to demonstrate, employing two parametric forms of the Markowitz model of utility, that heterogeneity of preferences of Markowitz agents can contribute towards an explanation of why lotteries typically have multiple rather than single prizes.

In this paper we give a survey of recent work on game theory devoted to modeling decision making under bounded rationality. An agent's deviation from rational choice understood as maximization of gain can be caused by moral principles (religious beliefs, altruism, patriotism), emotions (envy,...

This paper analyzes increased risk aversion in the presence of two risks. Necessary and sufficient conditions for increased risk aversion across the domain of the foreground risk are found for changes in both the foreground and background risks. Preferences that satisfy the necessary and...

This paper develops a model of reference-dependent assessment of subjective beliefs in which loss-averse people optimally choose the expectation as the reference point to balance the current felicity from the optimistic anticipation and the future disappointment from the realization.The choice...

We demonstrate theoretically and illustrate the implications of assuming power utility when the true function is of the expo-power form. Empirical results can appear to be consistent with cumulative prospect theory when they are in fact generated from a Markowitz model.

In this paper we give a survey of recent works on game theory devoted to modeling of decision making process under bounded rationality. An agent's deviation from rational choice understood as maximization of gain can be caused by moral principles (religious beliefs, altruism, patriotism),...

The main goal of this study is to analyse the ability of the implied volatility index (VIX) to incorporate current stock market information that is relevant for the volatility forecasts. Employing historical market volatility, market trading volume and significant stock market returns as...

The paper aims to present a comparative study regarding information system and knowledge management system within the Chamber of Commerce and Industry, study conducted based on questionnaire, over two years, namely 2012 and 2013. The study aims to focus on the differences between the two terms...

In the context of standard two-period pure-exchange economies with sequential trade, this paper proposes a decentralized coordination mechanism for equilibriumexpectations, facilitated by local interactions between agents. Interactions are modelled stochastically by specifying a family of...

We generalize the "No-trade" theorem for finite unawareness belief structures in Heifetz, Meier, and Schipper (2009) to the infinite case.
