Portfolio selection models based on second-order stochastic dominance (SSD) have the advantage of providing portfolios that reflect the behavior of risk-averse investors without the need to specify the utility function. Several scholars apply SSD conditions with respect to a reference distribution, typically that of the market index, to find its dominant SSD portfolio. However, since the reference distribution could strongly influence asset allocation, in this article, we compare two SSD-based portfolio selection strategies with a reshaping of the reference distribution in terms of its skewness and, consequently, its variance. Through an extensive empirical analysis based on multiasset investment universes, we empirically show that the SSD portfolios dominating the new skewed benchmark index generally perform better.

In this paper, we revisit the classic problem of a wave field on a sloping beach of an arbitrary angle and propose a general approach that allows the computation of regular solutions of the problem regardless of the angle. We use the Mellin-transform technique, reducing the problem to singular integral equations with fixed-point singularities of ...

This study reassesses whether economic globalization is compatible with carbon mitigation across nine Shanghai Cooperation Organization economies over 1997 to 2024. A sequenced panel design is applied: pre-estimation diagnostics establish cross-sectional dependence, slope heterogeneity, and mixed integration orders; fixed effects with Driscoll and Kraay standard errors provides the preferred conditional mean estimate; Hansen threshold regression, ...

The matrix profile (MP) quickly became one of the most important time series preprocessing methods when it was introduced in 2016, facilitating the solution of a wide range of time series analysis problems, in particular anomaly and pattern detection problems. The high significance has led to the emergence of various tools for MP calculating, but ...

To mitigate the shocks caused by the pandemic-related restrictions, many governments implemented extensive support measures for companies facing sharp declines in revenues. In Russia, loan guarantee programmes allowed many firms to apply for loans during the pandemic. As a result, the number of small loans soared. Participation in the loan guarantee programmes helped firms in ...

This article concerns the study of modulational instability in the rotated-modified Gardner–Whitham (rmGW) equation. This model incorporates both quadratic and cubic nonlinearities, similarly to the Gardner equation, while also retaining the fully dispersive character of the Whitham equation together with a large-scale dispersive term analogous to that in the Ostrovsky equation. Using a classical multiple-scale asymptotic expansion, we ...

The cryptocurrency market has been considered until recently a market for private, non-portfolio investors, and the research focus has been on volatility. However, gradual institutionalization and creation of ETFs have highlighted new characteristics, including the asymmetry of trade behavior. Our research aims to analyze the relationships between asymmetric risk indicators and the returns of portfolios ...

Nonlinear wave-induced perturbations are discussed within the framework of the second-order theory. Due to the slow attenuation of the long perturbations with depth, they modulate motions beneath surface waves down to the bottom and can strongly affect the wave statistics. The disturbance which corresponds to the second harmonic, at a sufficient depth, inverses the phase, thereby ...

The global pandemic provokes a new round of volatility, which is fundamentally different, so the modern stage of development actualizes the task of determining regional economic systems' trajectories.

Portfolio optimization is a large area of investigation both in theoretical and practical setting since the seminal work by Markowitz where a mean-variance model was introduced. From optimization point of view, the problem of optimal portfolio in mean-variance setting can be formulated as convex quadratic optimization under uncertainty. In practice one needs to estimate parameters ...

Mathematical programming is often concerned with determining the optimum of some real-world objective. One of the main questions in this field is the way of addressing uncertainty. Whereas deterministic optimization models are formulated with known parameters, real life issues almost invariably include uncertain parameters which are unknown at the time when a decision should be ...

This paper, following (Ghalanos, 2012), uses the simple method of embedding skewness in asset allocation based on the Taylor expansion of the investor utility function up to the third term and maximizing it by portfolio weights. This approach also enables us to consider investor risk aversion. Time-dependent multivariate asset moments are obtained via the GO-GARCH ...
