Stochastic debt sustainability analysis for sovereigns and the scope for optimization modeling
2017
We argue that sovereign debt sustainability analysis must be augmented by stochastic correlated risk factors and a risk measure to capture tail effects. Crisis situations can thus be adequately specified and analyzed with sufficient accuracy to warrant the relevance of policy decisions. In this context there is significant scope for optimization modeling for both strategic planning and operational management. We discuss diverse aspects of the problem of debt sustainability and highlight modeling approaches that can be brought to bear on the problem. Results with the fictitious, but nor unrealistic, Kingdom of Atlantis, which is sinking under excessive debt, illustrate the proposed models.
Landfill Culture: Some Implications to Degrowth
2016
To some extent, waste is just one more sign of the unsustainability of growth. Waste from industrial and socio-economic metabolism must be understood as any unusable material left over after a job, function or operation has been completed, which however, retains the ability to disrupt natural systems and interfere with them as one of its inherent properties. As part of such waste, Municipal Solid Waste (MSW) represents the unusable (or underused) and rejected fraction of the material resources mobilized by the sophisticated urban and/or industrial ecosystem. Although the volume of MSW is relatively small compared to other waste types, it is increasingly important as a result of its steady r…
The Impact of CSR/ESG Reporting on the Cost of Capital: An Example of US Healthcare Entities
2021
PURPOSE: Identifying the direction and strength of the relationship between individual elements of ESG and ESG as a whole and the cost of capital (weighted average, equity, and debt) in the healthcare industry.
Desafíos para el mantenimiento de una esfera pública democrática en la sociedad digital
2023
El presente trabajo se propone analizar cómo el creciente protagonismo de las redes sociales en el debate público puede implicar –de forma contraintiutiva- serios riesgos para la construcción y el mantenimiento de una esfera pública democrática. Para ello, en primer lugar, se identificarán las que hasta ahora han sido consideradas como características esenciales de una esfera pública democrática, exponiendo cómo dichas características han sido reconocidas y protegidas en los ordenamientos jurídicos –tomando como referencia el ordenamiento jurídico español. Enumeradas estas características, el trabajo analiza cómo la dinámica de las redes sociales puede poner en jaque cada una de ellas. Pres…
Fast nonstationary preconditioned iterative methods for ill-posed problems, with application to image deblurring
2013
We introduce a new iterative scheme for solving linear ill-posed problems, similar to nonstationary iterated Tikhonov regularization, but with an approximation of the underlying operator to be used for the Tikhonov equations. For image deblurring problems, such an approximation can be a discrete deconvolution that operates entirely in the Fourier domain. We provide a theoretical analysis of the new scheme, using regularization parameters that are chosen by a certain adaptive strategy. The numerical performance of this method turns out to be superior to state-of-the-art iterative methods, including the conjugate gradient iteration for the normal equation, with and without additional precondi…
How costly are debt crises?
2011
The aim of this paper is to assess the short- and medium-term impact of debt crises on GDP. Using an unbalanced panel of 154 countries from 1970 to 2008, the paper shows that debt crises produce significant and long-lasting output losses, reducing output by about 10 percent after eight years. The results also suggest that debt crises tend to be more detrimental than banking and currency crises. The significance of the results is robust to different specifications, identification and endogeneity checks, and datasets.
INNOVAZIONE DEI MATERIALI NATURALI: TERRA E NANOTUBI DI ARGILLA PER UNA SFIDA SOSTENIBILE
2019
All’interno del dibattito culturale che vede la questione ambientale come prioritaria e con riferimento a studi e ricerche che negli ultimi anni hanno promosso materiali compositi a base di terra cruda, gli Autori, consapevoli della necessità che il rapporto fra Progetto e Materia debba assumere una nuova centralità supportato dalle specificità della Tecnologia dell’Architettura, illustrano le risultanze di una sperimentazione che ha l’obiettivo di migliorare le prestazioni della terra cruda con l’apporto delle nanotecnologie, sviluppando un ‘nuovo materiale’ con una ridotta embodied energy e una ridotta quantità di emissioni di CO2 in atmosfera.
A Promising New Method to Estimate Drug-Polymer Solubility at Room Temperature
2016
The established methods to predict drug-polymer solubility at room temperature either rely on extrapolation over a long temperature range or are limited by the availability of a liquid analogue of the polymer. To overcome these issues, this work investigated a new methodology where the drug-polymer solubility is estimated from the solubility of the drug in a solution of the polymer at room temperature using the shake-flask method. Thus, the new polymer in solution method does not rely on temperature extrapolations and only requires the polymer and a solvent, in which the polymer is soluble, that does not affect the molecular structure of the drug and polymer relative to that in the solid st…
24/7 Society—The New Timing of Work?
2018
Public debate on societal rhythms, in particular working hours, has been dominated by a (fear) scenario about a shift towards a 24/7 society. Factors such as the services- and information-driven economy, deregulation of opening hours, changes in the rhythms of consumer culture have been expected to disrupt “normal” working time. The term ‘24/7 society’ is part of the popular discussion and occasionally encountered in academic writing as well. 24/7-society is expected to create both new opportunities and new risks. In this chapter, we produce up-to-date literature review to examine how the post-industrial, services-dominated economy changes work and leisure time practices. This chapter also …
The global economic crisis as a critical Juncture? The crisis's impact on migration movements and policies in Europe and the US
2016
The current global economic crisis has resulted in the strongest recession in the Organisation for Economic Cooperation and Development (OECD) countries since the Great Depression in the early 1930s and the 1970s oil shocks. This special issue sets out to explore how the most recent economic crisis impacted immigration and immigration-related policy in the United States of America and in European countries that are part of the OECD. The crisis of the late 2000s was offset by the collapse of the subprime US housing market, destabilising the financial system and leading to a sovereign debt crisis. The shock was marked by a “sudden […] deterioration of most, or all, key macroeconomic indicator…
