Toward a formalization of a two traders market with information exchange

2014

This paper shows that Hamiltonians and operators can also be put to good use even in contexts which are not purely physics based. Consider the world of finance. The work presented here {models a two traders system with information exchange with the help of four fundamental operators: cash and share operators; a portfolio operator and an operator reflecting the loss of information. An information Hamiltonian is considered and an additional Hamiltonian is presented which reflects the dynamics of selling/buying shares between traders. An important result of the paper is that when the information Hamiltonian is zero, portfolio operators commute with the Hamiltonian and this suggests that the dy…

The effects of monetary policy shocks on inequality

2018

Abstract This paper provides new evidence of the effect of conventional monetary policy shocks on income inequality. We construct a measure of unanticipated changes in policy rates—changes in short-term interest rates that are orthogonal to unexpected changes in growth and inflation news—for a panel of 32 advanced and emerging market countries over the period 1990–2013. Our main finding is that contractionary monetary policy shocks increase income inequality, on average. The effect is asymmetric—tightening of policy raises inequality more than easing lowers it—and depends on the state of the business cycle. We find some evidence that the effect increases with the share of labor income and i…

Inflation shocks and income inequality

2019

Purpose The purpose of this paper is to analyze the effects of inflationary shocks on inequality, using data of selected countries of the Middle East and North Africa (MENA). Design/methodology/approach Inflationary shocks were measured as deviations from core inflation, based on a genetic algorithm. Bayesian quantile regression was used to estimate the impact of inflationary shocks in different levels of inequality. Findings The results showed that inflationary shocks substantially affect countries with higher levels of inequality, thus suggesting that the detrimental impact of inflation is exacerbated by the high division of classes in a country. Originality/value The study contributes t…

Input-Output Finite-Time Stability of Discrete-Time Impulsive Switched Linear Systems with State Delays

2013

Published version of an article in the journal: Circuits, Systems, and Signal Processing. Also available from the publisher at: http://dx.doi.org/10.1007/s00034-013-9610-7 This paper is concerned with the problem of input-output finite-time stability (IO-FTS) for discrete impulsive switched systems with state delays. Sufficient conditions are presented for the existence of IO-FTS for such systems under the cases of certain switching, arbitrary switching, and uncertain switching. All the obtained results are formulated in a set of linear matrix inequalities (LMIs). Two numerical examples are given to illustrate the effectiveness of the proposed results.

Conditions of cultural citizenship: intersections of gender, race and age in public debates on family migration

2015

This article analyses problem framings in public debates on family migration in Finland. The study focuses on the less-examined category of age and how it intersects with gender, race and religion. We examine the discursive context within which parliamentarians and the media negotiate questions of migration policies, belonging and citizenship. Our analysis identifies problem framings by combining frame analysis with the ‘What is the problem represented to be?’ approach, which understands policies as problematizations. We found that the debates held up the rather common notion of vulnerable women and children as groups that tighter family migration policies protect. The debates excluded cert…

Disaster Risk Reduction for All? Understanding Intersectionality in Disaster Situations

2021

When designing digital services for citizens in a disaster situation, the diversity of its audience and their particular needs are not always sufficiently taken into account. Variables like digital equipment available, environment, disabilities, socio-economic status, etc., play a significant role in people’s ability to access and exchange important information through digital means. In this paper, we will examine some factors that lead to this inequality, and we see that they tend to boil down to a lack of awareness or focus on the diversity of the population, and this affects not only people with disabilities, but also other disadvantaged groups. More broadly, we will examine this in term…

"""Fluidity and flexibility of """"belonging"""": Uses of the concept in contemporary research"""

2016

Studies framing “belonging” as a key focus and a central concept of research have increased significantly in the 2000s. This article explores the dimensions of belonging as a scholarly concept. The investigation is based on a qualitative content analysis of articles published in academic journals covering a large number of different disciplines. The article poses and answers the following research questions: How is belonging understood and used in contemporary research? What added value does the concept bring to scholarly discussions? In the analysis, five topoi of conceptualizing belonging – spatiality, intersectionality, multiplicity, materiality, and non-belonging – were identified. Afte…

Compensating inequalities in secondary education in France: studies from the PISA, CEDRE and TALIS surveys

2017

The fight against educational inequality is one of the foundational principles of education in France. Implementing equal opportunity and the fight against social and geographical inequality are inscribed in the first article in the Code of Education. However, educational inequality persists and has continued to increase these past years. Using data sets from threedifferent international and national evaluations (PISA, Cedre, and TALIS), this dissertation seeks to bring a new perspective on the reduction of inequality for students enrolled in secondary education in France.

Justice et inégalités: un amendement à la théorie de John Rawls

1992

National audience; On se demande si les principes de justice de Rawls ne sont pas exagérément inégalitaires, malgré leur côté "juste". On examine donc ce qu'il advient de l'optimum de Rawls, le maximin, quand de l'aversion pour l'inégalité" apparaît. Le maximin consiste à se placer sur un certain point de la courbe d'efficience, en admettant une certaine dose d'inégalité, pourvu que l'on donne le maximum possible aux plus défavorisés. On tient compte d'externalités en reprenant la notion d'envie sous la forme d'une aversion pour l'inégalité, essentiellement de la part des plus défavorisés. On ne peut plus raisonner sur la courbe frontière des rémunérations possibles et on démontre la validi…
