Introduction: Wikis are multiuser platforms that have been used with positive results for learning in higher education. As knowledge artefacts they include both semiotic and material aspects that could potentially be realized through collaborative learning and the assessment of interprofessional and problem based learning using portfolios. Purpose: The aim of the present study is to investigate...

in this thesis we predict asymmetric risk premium in bothvalue and growth stock portfolios. there are two competingapproaches to explain value premium: market over-reactionhypothesis based on which agents overstate future returns on growthstock, and rational market risk hypothesis that says value stocks areinherently riskier than growth stocks. rational market riskhypothesis has two different e...

Classic, and Explicit Turnpikes Paolo Guasoni · Constantinos Kardaras · Scott Robertson · Hao Xing Received: date / Accepted: date Abstract Portfolio turnpikes state that, as the investment horizon increases, optimal portfolios for generic utilities converge to those of isoelastic utilities. This paper proves three kinds of turnpikes. In a general semimartingale setting, the abstract turnpike s...

Portfolio optimization methods suffer from a catalogue of known problems, mainly due to the facts that pair correlations asset returns are unstable, and extremal risk measures such as maximum drawdown difficult predict non-Gaussianity portfolio returns. \\ In order look at optimal portfolios for arbitrary penalty functions, we construct shapes where is proportional moment $p>2$. The resulting c...
