this paper presents dynamic portfolio model based on the merton's optimal investment-consumption model, which combines dynamic synthetic put option using risk-free and risky assets. this paper is extended version of methodological paper published by yuan yao (2012) cite{26}. because of the long history of the development of foreign financial market, with a variety of financial derivatives, the ...

in traditional portfolio selection model coefficients often are certain and deterministic, but in real world these coefficients are probabilistic. so decision maker cannot estimate them exactly. financial optimization is one of the most attractive areas in decision under uncertainty. in the portfolio selection problem the decision maker considers simultaneously conflicting objectives such as ra...

Residential property has long been recognised as an important component in a household’s overall wealth. The sheer magnitude of purchasing a house has compelled households to commit a disproportionate amount of their funds to own a house, leaving little capital for other kinds of investment. The findings of this study show that an allocation between 50% to 65% of the available capital to reside...

In this paper, the investment portfolio is formed based on the data mining algorithm of CHAID on the basis of the risk status criteria. In the next step, the second investment portfolio is created based on the decision rules extracted by the DEA-BCC model. The final portfolio is created through a two-objective mathematical programming model based on the Imperialist Competitive algorithm.

empirical studies show that there is stronger dependency between large losses than large profit in financial market, which undermine the performance of using symmetric distribution for modeling these asymmetric. that is why the assuming normal joint distribution of returns is not suitable because of considering the linier dependence, and can be lead to inappropriate estimate of var. copula theo...

this research aims to design the portfolio entrepreneurship model and to analyze the effect of social capital, prior experience and knowledge, the entrepreneur’s financial resources, as well as human capital on portfolio entrepreneurship and also to investigate the effect of portfolio entrepreneurship on recognition of new opportunities, as well as business growth and development. the research ...

The increasing ubiquity of information systems in organizations has been accompanied by a rise in users adopting technology that is not officially mandated (often known as shadow IT). This study examines the emergence and consequences of such locally-driven but centrally-unintended adaptations of an organization’s collection of IT assets. This phenomenon, referred to as “IS portfolio drift, can...

Projects scheduling by the project portfolio selection, something that has its own complexity and its flexibility, can create different composition of the project portfolio. An integer programming model is formulated for the project portfolio selection and scheduling.Two heuristic algorithms, genetic algorithm (GA) and simulated annealing (SA), are presented to solve the problem. Results of cal...
