A welfare analysis of a risky policy is impossible within a linear or linearized model and its certainty equivalence property. The presented algorithms are designed as a toolbox for a general model class. The computational challenges are considerable and I concentrate on the numerics and...

We present and evaluate a numerical optimization method (together with an algorithm for choosing the starting values) pertinent to the constrained optimization problem arising in the estimation of the GARCH models with inequality constraints, in particular the Simplified Component GARCH Model...

This paper introduces a new Empirical Mode Decomposition (EMD) Python package called AdvEMDpy that is demonstrably more flexible and which generalises in numerous important ways the existing EMD packages available in Python, R, and MATLAB. The extensions introduced by this AdvEMDpy package both...

We estimate time varying risk sensitivities on a wide range of stocks' portfolios of the US market. We empirically test, on a 1926-2004 Monthly CRSP database, a classic one factor model augmented with a time varying specification of betas. Using a Kalman filter based on a genetic algorithm, we...

This work serves as a formal supplement to ‘Package AdvEMDpy: Algorithmic Variations of Empirical Mode Decomposition in Python’ with additional synthetic and real-world examples. AdvEMDpy will be shown to be more accurate than its Python competitors in resolving the underlying driving...

This study is based on a sample of 100 customers of the Tunisian Post, the objective is to know the impact of digital transformation on the Tunisian Post through the D17 application. Based on our analysis; the results show that mobile payments constitute an attractive solution for individuals...

This article examines the relationship between nomenklatura membership, wealth accumulation and political ties across the post-Soviet region from the 1990s up to the mid-2010s. It introduces the Post-Soviet Oligarchs (PSO) dataset, containing the sociodemographic characteristics of the...

This paper shows some empirical results for the collective labor supply of households in thirteen developed countries (USA, UK, Australia, Canada, Belgium, Netherlands, Germany, France, Spain, Italy, Russia, Japan, and China). I have reviewed a significant number of papers in order to aggregate...

In this technical report the interest is placed on two multi-faceted indices, the Eco-innovation index and the Global Competitiveness Index of the EU 28 member states. The former index is produced by the Eco-innovation Observatory under the DG Environment of the European Commission covering the...

In this paper a Methodology for Integrated Socio-Economic Assessment (MISEA) of the viability and sustainability of different designs of Multi-Use Offshore Platforms (MUOPs) is presented. MUOPs are designed for multi-use of ocean space for energy extraction (wind power production and wave...
