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 ...

This paper examines the performance and diversification properties of active Australian equity fund-of-funds (FoF). Simulation analysis is employed to examine portfolio performance as a function of the number of funds in the portfolio. The paper finds that as the number of funds in a FoF portfolio increases, performance improves in a mean-variance setting, however measures of skewness and kurto...

The professional Electronic Leadership Portfolio (ELP) is an effective method for the promotion of Information and Communication Technology (ICT) in the educational arena, both as a model for aspiring leaders and as a model for the necessary development of skills in teachers. Furthermore, the ELP provides a framework for future measurement of leadership skills and development as well as providi...

Along with the advance of opinion mining techniques, public mood has been found to be a key element for stock market prediction. However, in what manner the market participants are affected by public mood has been rarely discussed. As a result, there has been little progress in leveraging public mood for the asset allocation problem, as the application is preferred in a trusted and interpretabl...

In performance evaluation, it is important to identify both the efficient frontier and the critical measures. Data envelopment analysis (DEA) has been proven an effective tool for estimating the efficient frontiers, and the optimized DEA weights may be used to identify the critical measures. However, due to multiple DEA optimal weights, a unique set of critical measures may not be obtained for ...

We develop a numerical scheme for determining the optimal asset allocation strategy for time-consistent, continuous time, mean variance optimization. Any type of constraint can be applied to the investment policy. The optimal policies for time-consistent and pre-commitment strategies are compared. When realistic constraints are applied, the efficient frontiers for the precommitment and time-con...

The Next Generation Air Transportation System (NextGen) represents the transformation of the National Airspace System, including our national system of airports, using 21st century technologies to ensure future safety, capacity and environmental needs are met. NextGen will be realized through investments in research and development, technologies, operational changes, and the coordinated efforts...

DeMiguel, Garlappi, and Uppal (Review of Financial Studies, 22 (2009), 1915–1953) showed that in the stock market, it is difficult for an optimized portfolio constructed using meanvariance analysis to outperform a simple equally-weighted portfolio because of estimation error. In this paper, we demonstrate that portfolio optimization can be made to work in currency markets. The key difference be...
