This paper presents a consumption-based asset pricing model to explain the equity premium and riskfree puzzles as well as the predictability of returns in the international equity markets. We find that because the model entails idiosyncratic consumption risk which is higher than the aggregate consumption risk, the model helps lower the investor risk aversion needed to explain the mean equity pr...

Electronic trading of equities and other securities makes heavy use of “arrival price” algorithms, that determine optimal trade schedules by balancing the market impact cost of rapid execution against the volatility risk of slow execution. In the standard formulation, mean-variance optimal strategies are static: they do not modify the execution speed in response to price motions observed during...

The mean-variance (MV) portfolio is typically formulated as a quadratic programming (QP) problem that linearly combines the conflicting objectives of minimizing risk and maximizing expected return through aversion profile parameter. In this formulation, two are expressed in different units, an issue could definitely hamper obtaining more competitive set weights. For example, modification scale ...

In this paper we tackle the optimal portfolio selection problem (PSP). Many research has been made around this subject mainly in two ways, whether extending the Markowitz model by taking into account real-world constraints (floor-ceiling, class and cardinality) or introducing different risk measures like semivariance, value at risk, absolute desviation, etc. Here, we present the preliminary res...

Abstract The asset-liability management problem with cash flow under an uncertain exit time has been investigated in this article, which is based on the fundamental framework of mean-variance model multi-period version. liability and random will affect asset optimization, while investor may be forced to withdraw from investments a probability at each period our model. closed-form expressions fo...
