[more ▼]The determinants of the direction of technical change and their implications for economic growth and economic policy are studied in the one-sector neoclassical growth model of Ramsey, Cass, and Koopmans extended to allow for endogenous capital- and labor-augmenting technical change. We develop a novel micro-foundation for the competitive production sector that rests on the idea that the fabrication of output requires tasks to be performed by capital and labor. Firms may engage in innovation investments that increase the productivity of capital and labor in the performance of their respective tasks. These investments are associated with new technological knowledge that accumulates over time and sustains long-run growth. We show that the equilibrium allocation is not Pareto-efficient since both forms of technical change give rise to an inter-temporal knowledge externality. An appropriate policy of investment subsidies may implement the efficient allocation.

[more ▼]The current times of constitutional transformation in the EU place the following question on the agenda: Is the ongoing economic crisis demarcating the end of the original conception of a ‘European Economic Constitution’ as it has developed since the early days of the EEC? Or are we witnessing simply a shift towards a new more encompassing model of an EU ‘Economic Constitution’ in which economic government and economic governance tools are used in parallel to deepen integration and continue the spill-over of economic integration into previously national policies? This contribution traces and evaluates conceptual, regulatory, institutional and legitimacy-related changes and challenges to the EU’s model of the ‘Economic Constitution’ as the basic legal framework and conceptions of EU law governing economic policy. This chapter argues that the EU’s constitutional framework in the form of the existing Treaties and General Principles of EU law did not provide an adequate legal framework to cope with the ongoing crisis. This failure has, in our view, initiated an ongoing transformation of the EU’s ‘Economic Constitution’ as we know it. Laying the foundations for the transformation took place in several consecutive steps mostly on the intergovernmental level and often as a combination of EU law, public international law and in some cases mixed with private law instruments. The nature of this development creates challenges regarding ensuring compliance of these newly developed structures with the Union’s foundational principles of ensuring transparency, democratic legitimacy, fundamental rights and effective review mechanisms in the context of a system under the rule of law. In order to illustrate the modes of the continuous transformation of the ‘Eoncomic Constitution’ and to evaluate the direction it is taking, this chapter will start with tracing its origins and follow its evolution over time. It thereby distinguishes two separate but interlinked elements of the ‘Economic Constitution.’ It first looks at the original focus of European regulation regarding what we refer to as ‘micro-economic’ matters with policies including competition law and the control of state aids. This chapter then turns to the evolving focus of EU law the larger questions of economic and fiscal policies which we refer to in the following as the ‘macro-economic’ element of the constitutional framework.

[more ▼]This paper investigates whether a less-developed economy can catch up with a more developed one when they compete for foreign direct investments. The main message of the paper is that jurisdictional competition can enable the lagging country to catch up if capital mobility is sufficiently high and the productivity gap is not too large. Further, we show that size asymmetry reinforces (weakens) the productivity catch-up resulting from interjurisdictional competition when the lagging economy is small (large). Finally, we demonstrate that the development gap widens when capital becomes less mobile, which is at odds with previous findings.

[more ▼]We examine the issue of stability of stochastic endogenous growth. First, stochastic stability concepts are introduced and applied to stochastic linear homogenous differen- tial equations to which several stochastic endogenous growth models reduce. Second, we apply the mathematical theory to two models, starting with the stochastic AK model. It’s shown that in this case exponential balanced paths, which characterize optimal trajectories in the absence of uncertainty, are not robust to uncertainty: the economy may almost surely collapse at exponential speed even though productivity is initially arbitrarily high. Finally, we revisit the seminal global diversification endogenous growth model (Obstfeld, 1994): taking into account stochastic stability calls for a redefinition of the mean growth concept, which leads to revisit the established wisdom on the growth effect of global diversification.

These workers commute daily from France, Belgium and Germany to Luxembourg. Their presence in the national labour market results in increasing linguistic and cultural diversity at Luxembourgish workplaces. Drawing upon interview and interactional data, the present contribution is the first to investigate how cross-border workers in Luxembourg perceive and deal with multilingualism and interculturality, and presents a range of related linguistic and intercultural practices.

[more ▼]Les frontières se différencient non seulement en fonction des domaines d'étude où elles sont opérantes ou dans lesquels elles se constituent, mais également en termes de modes de (re)production et de formes. Cette communication traitera en premier lieu de la forme de la frontière, sachant que ce n’est pas la frontière territoriale en tant que ligne qui importera, mais plutôt son caractère zonal et la question de savoir comment il est possible de l'aborder dans une perspective théorico-conceptuelle aux fins de l’étude empirique. Il est plus judicieux de considérer les frontières territoriales comme zones ou espaces, la métaphore de la ligne s'avérant une pure fiction. Jusqu’au XVIIIe siècle, les frontières étaient conçues comme des espaces de contact et des zones de transition (convoitées), ce n’est qu’avec l’avènement d’États nationaux modernes que s’établit le concept de frontière comme ligne – sans qu’elle n’ait perdu empiriquement son caractère zonal. C’est ce qu’on peut notamment constater dans les régions transfrontalières où les frontières territoriales ne peuvent se réduire à leur fonction de différenciation ou de passerelle, mais au contraire s’élargissent – comme le montre la mobilité transfrontalière des travailleurs, des consommateurs ainsi que la mobilité résidentielle – se transformant ainsi en zones de l'entre-deux. Ces zones ne peuvent pas être concédées aux espaces situés en deçà et au-delà d’une frontière territoriale, elles représentent en revanche des espaces autonomes, lesdits « espaces de frontière » qui revêtent une identité liminale. L'objet de cette communication est de savoir comment il est possible de décrire et d'étudier de tels espaces que l'on peut observer comme productions quotidiennes. Il s’agit (1) de percevoir de manière conceptuelle le caractère zonal de la frontière, donc la dimension spatiale, (2) le potentiel innovateur et imprévisible de la liminalité et ainsi la contingence sociale. La géographie sociale et la sociologie de la culture en livrent des points de départ pertinents. La mise en relation d’approches concernant l’espace et la pratique sociale issues de ces deux disciplines représente la base du modèle « espaces de frontière » qui permet de penser les frontières en tant qu’espaces et met en place une heuristique destinée à l’étude de constitutions spatiales centrées sur le sujet comme (re)productions des frontières. Les pratiques sociales, la connaissance pratique ainsi que les aspects physico-matériels et socio-structurels tels qu'ils sont appropriés et engendrés par les « frontaliers » dans des références transfrontalières, font partie des catégories d'analyse.

[more ▼]Much research on multilingualism in advertising has been undertaken in comparatively mono-lingual settings. Whereas such research may provide insights into the connotations of lan-guages used in advertising, research in more multilingual contexts can also provide different kinds of insights regarding the relative status of languages in a multilingual environment. This article focuses on multilingualism in written advertising in the highly multilingual setting of Luxembourg, where the language situation is currently undergoing significant change due to patterns of globalisation and migration. Analysis of a mixed corpus of advertisements, includ-ing 1,038 advertisements in the free daily newspaper l’Essentiel from 2009 to 2011, as well as selected further advertisements from elsewhere within Luxembourg’s linguistic landscape, reflects a move within Luxembourg in general from a longstanding trilingualism in French, German and Luxembourgish to different kinds of multilingualism, incorporating both the presence of new languages and changes in the relative roles of French, German and Luxem-bourgish. Particularly significant is the presence of Luxembourgish as a written language of advertising, whereas it traditionally functioned mainly as a spoken language in Luxembourg. The article presents the results of a quantitative and qualitative analysis of the advertisements and discusses how multilingualism in written advertising provides a pertinent window on changing forms of multilingualism in Luxembourg.

[more ▼]This paper examines the extent to which well-being levels change in the transition to retirement depending on transitioning from being employed, unemployed, or economically inactive. Whereas transitioning from employment to unemployment has been found to cause an increase in depressive symptoms or decline in life satisfaction with more time spent in unemployment, it is not clear to which extent transitioning from unemployment to retirement affects well-being levels compared to retiring after being employed or economically inactive. We use two waves of the Survey of Health, Ageing and Retirement in Europe monitoring respondents transitioning to retirement and use life satisfaction as well-being measure. The effect of the transition is captured with a difference-in-difference like approach to test if the change in well-being after retirement is different for persons who were formerly unemployed or inactive, respectively, compared to formerly employed retirees. Results indicate that retiring from unemployment is associated with an increase in life satisfaction, but presents mainly a catching-up effect compared to employed persons transitioning to retirement. Retirement from labour market inactivity, especially sick leave, does not lead to significant changes in well-being. Findings are robust to selection into unemployment and country differences. As well-being of unemployed persons recovers after transitioning to retirement, especially the currently unemployed population should be supported to prevent detrimental consequences of economically unfavourable conditions and lower well-being.

[more ▼]This paper summarises the findings of a questionnaire study investigating the language pro-files and practices of cross-border workers in Luxembourg. The study was undertaken in 2009 and includes 128 cross-border workers from 35 workplaces from different sectors, including the health sector, higher education and research, the manufacturing industry and the service sector. The study suggests that all the participants have a multilingual profile and have learnt at least one language in addition to their first one in the course of their life. A second result is that French is used in all the workplaces under investigation. But, at the same time, the major-ity of the cross-border worker participants have a multilingual professional life, most of them using more than one language at work on an everyday basis. This multilingualism comes in the form of a wide range of multilingual practices, including language accommodation, use of a lingua franca, code-switching and receptive multilingualism. Furthermore, two thirds of the participants report having learnt Luxembourgish either formally or informally, and half of those who have not learnt it, would like to do so in the future.

Utilizing a panel of German companies in manufacturing industries from 1993-2011, this analysis explicitly distinguishes between radical and incremental innovation output. It reveals that firm size and radical innovation share an overall negative relationship, while the relationship between firm size and incremental innovation is positive. These results provide a novel explanation for the often-reported non-linear relationship between firm size and innovation.

[more ▼]This paper uncovers strong return reversals in the US value weighted stock market index around the last monthly settlement day, T-3, which guarantees liquidity for month-end cash distributions. Similar reversals in market returns around T-3 are documented internationally. The return reversals are stronger in countries where the mutual fund ownership is large, and in the US they have become stronger over time as the mutual fund ownership of stocks has increased. Using data that contains all trades of a subset of institutional investors, we show direct evidence that institutional trading contributes to the market reversals. Finally, we find that in the cross-section of stocks, return reversals around the turn of the month are stronger for stocks more commonly held by mutual funds and for liquid stocks. These market reversals help explain the previously documented abnormally high market returns around the turn of the month.

At long horizons, return predictability drives the variation in the exchange rate while predictability of future interest rate differentials plays a secondary role. At shorter horizons, the dominant source is predictability of the future spot rate. There is more return predictability and less interest spread and exchange rate predictability in the case of real exchange rates compared to nominal exchange rates. An alternative decomposition based on a first-order VAR tends to overstate the importance of predictability of future interest spreads and exchange rates.

The subbundle D plays the role of an orthogonal complement to the leaves of the foliation in case (a) and of a principal connection in case (b).

[more ▼]Work Package 7 aims at understanding how early job insecurity can affect an individual’s future career from an employer’s perspective. By paying special attention to the educational background and gender of the applicants, we plan to investigate how employers interpret young applicants’ job insecurity, for example in the form of unemployment or job-mismatch experiences, during recruitment. The negative effects of such experiences on an individual’s chances of being recruited successfully – so called scarring effects – may further vary depending on economic and institutional contexts such as country-specific economic or political conditions, educational structures or economic sectors. By surveying employers from different sectors, we will examine if and how these scarring effects vary between four different countries: Bulgaria, Greece, Norway and Switzerland. We will apply an innovative methodology in the form of an employer-sided survey with an integrated multidimensional vignette experiment in order to simulate the impact of multiple factor s on success and failure when young people who experienced job insecurities apply for new jobs. In the present working paper we summarise the major theoretical concepts that have been used to explain the scarring effects that can result from employer behaviour. Moreover, we outline how we plan to collect data in WP 7 in order to analyse scarring through decision-making on behalf of employers during the recruitment process [less ▲]Detailed reference viewed: 112 (11 UL) Flat Z-graded connections and loop spacesArias Abad, Camilo; Schatz, Florian E-print/Working paper (2015)The pull back of a flat bundle E→X along the evaluation map π:LX→X from the free loop space LX to X comes equipped with a canonical automorphism given by the holonomies of E.

[more ▼]We introduce two new algorithms to minimise smooth difference of convex (DC) functions that accelerate the convergence of the classical DC algorithm (DCA). We prove that the point computed by DCA can be used to define a descent direction for the objective function evaluated at this point. Our algorithms are based on a combination of DCA together with a line search step that uses this descent direction. Convergence of the algorithms is proved and the rate of convergence is analysed under the Łojasiewicz property of the objective function. We apply our algorithms to a class of smooth DC programs arising in the study of biochemical reaction networks, where the objective function is real analytic and thus satisfies the Łojasiewicz property. Numerical tests on various biochemical models clearly show that our algorithms outperforms DCA, being on average more than four times faster in both computational time and the number of iterations. The algorithms are globally convergent to a non-equilibrium steady state of a biochemical network, with only chemically consistent restrictions on the network topology.

[more ▼]We introduce a model of strategic environmental policy where two firms compete à la Cournot in a third market in the presence of multiple pollutants. Two types of pollutants are introduced: a local and a transboundary one. The regulator can only control local pollution as transboundary pollution is regulated internationally. The strategic effect present in the original literature is also replicated in this setup. However, we illustrate that when transboundary pollution is regulated through the use of tradable emission permits instead of non-tradable ones then a new strategic effect appears which had not been identified thus far. In this case, local pollution increases further and welfare is lowered. We also provide evidence from the implementation of EU ETS over the pollution of particulate matters (PM10 and PM2.5).

We model a stationary industry where the observed size distribution is a solution to the profit maximization problem of heterogeneous firms that di¤er in terms of their energy e¢ ciency. We compare the equilibrium size distribution under emission taxes, uniform emission standards, and performance standards. Our results indicate that, unlike emission taxes and performance standards, emission standards introduce regulatory asymmetries favoring small firms. These asymmetries cause significant detrimental e¤ects on total output and total welfare, yet lead to reduced emissions and might help preserve small businesses.

[more ▼]It is conventionally assumed that administrative discretionary decisions are determined by political and expert-driven considerations and that law’s structuring and constraining capacity in that regard is and should be limited. Law defines a space within which discretionary choices are irrelevant to law because they have the same legal value. These tenets have shaped both the ways the Court of Justice of the European Union has approached judicial review of discretion and, more generally, the way law is perceived to structure administrative discretion in the Member States and also in the EU. However, the recent expansion of the regulatory powers of the European Union justifies revisiting these basic axioms. In particular, how far should discretion be shielded from the values that EU law conveys? This paper proposes a normative elaboration of a core idea of public law to stress that law twins administrative discretion with a duty of regard to pre-determined public interests. On this basis, legal rules are able to provide a yardstick of critique of decisions that administrative officials adopt within spaces of discretion. An analysis of the Meroni judgment shows how this argument applies to EU law. But this claim only prepares the ground for a more complex inquiry: How does law operate – and how should it operate – within the spaces of administrative discretion, and how should courts review discretionary decisions? Administrative decision-makers construct the law in a specific institutional context in view of their specific tasks. Arguably, one should understand the specific processes through which they interpret the law to know how law may provide substantive criteria that guide discretionary choices. Such understanding would also be the basis to define and assess suitable degrees of judicial review of administrative discretion. One could then make a critical assessment – difficult to make at present – of the shifting boundaries between spaces of discretion and of judicial review that the dictum “manifest error of assessment, misuse of power or excess of power” conceals. This latter argument draws on the debate among US administrative law scholars on agency interpretation of statutes, but it is also mindful of conceptual distinctions that have prevailed in legal scholarship in Europe. The paper defines the prolegomena of a normative framework of a broader research project. It is work in progress.

[more ▼]Given a closed wide Lie subgroupoid$\mathbf{A}$of a Lie groupoid$\mathbf{L}$, i.e. a Lie groupoid pair, we interpret the associated Atiyah class as the obstruction to the existence of$\mathbf{L}$-invariant fibrewise affine connections on the homogeneous space$\mathbf{L}/\mathbf{A}$. For Lie groupoid pairs with vanishing Atiyah class, we show that the left$\mathbf{A}$-action on the quotient space$\mathbf{L}/\mathbf{A}$can be linearized. In addition to giving an alternative proof of a result of Calaque about the Poincare-Birkhoff-Witt map for Lie algebroid pairs with vanishing Atiyah class, this result specializes to a necessary and sufficient condition for the linearization of dressing actions, and gives a clear interpretation of the Molino class as an obstruction to simultaneous linearization of all the monodromies. In the course of the paper, a general theory of connections and connection forms on Lie groupoid principal bundles is developed. Also, a computational substitute to the adjoint action (which only exists "up to homotopy") is suggested.

[more ▼]Most constitutions foresee a 'state of emergency' associated with the existence of an armed conflict. Paradoxically, modern societies seem to be permanently confronted with genuine emergencies increasingly removed from the threat of actual, physical violence. The Eurozone crisis can be said to have accentuated this, as the immense pressures from financial markets have turned the control of public finances into a struggle for the survival of the affected States. The present paper explores the legal manifestations of emergency in the domestic law of Greece, Italy, Spain and Ireland. These countries have all been hit by the Eurozone crisis (albeit in different manners) and have had to accommodate external oversight in their crisis management. The adoption of emergency measures for tackling the economic upheavals has been diverse across the case studies, although all have in common the emergence of a prominent role for the executive in the aftermath of the Eurozone crisis.

[more ▼]Despite temporary migration programmes (TMPs) being heralded as achieving a triple win – whereby the host state, the sending state and the migrants themselves all benefit – the UK government has now terminated all such programmes, including the longstanding Seasonal Agricultural Workers Scheme (SAWS). At the same time, TMPs have been heavily criticised by both the academic and policy sectors, as they tie workers to employers in rigid ways and lack integration measures. This paper reviews the SAWS scheme, including the policy evolution of the programme and the reasons for the closure. We argue that the government is inflicting a multiple loss scenario, whereby permanent immigration may increase, labour market shortages will be rife, remittances and skills transfers will be lost, and irregular immigration and in turn exploitation of migrant worker rights may be exacerbated. Whilst the policy design of SAWS was far from perfect, we argue that a modified version, targeting agricultural students, should be retained, which could restore the triple-win scenario.

Les hommes les appréhendent également moins que les femmes alors qu’ils en sont presque aussi souvent victimes. Parmi les personnes ayant subi de la violence physique entre 2008 et 2012, 38% en ont été victimes à plusieurs reprises. La plupart des agressions ont eu lieu au Grand-Duché (86%) et l’agresseur a le plus souvent agi seul (70%). 33% des victimes connaissaient leurs agresseurs de nom et dans 26% de ces cas il s’agissait de l’ex-conjoint.

[more ▼]The Inada (1963) conditions constitute a defining property of the neoclassical production function with capital and labor as arguments. Are these conditions justifiable on economic grounds? Yes, they are: we show that a production function with positive, yet diminishing marginal products and constant returns to scale satisfies the Inada conditions if i) both inputs are essential and ii) an unbounded quantity of either input leads to unbounded output. This allows for an alternative characterization of the neoclassical production function that altogether dispenses with the Inada conditions. Moreover, we establish that the marginal product of capital vanishes as capital goes to infinity if labor is an essential input. Given the intuitive appeal of the latter feature, we conclude that the neoclassical growth model is a theory of eventual stagnation.

Ce sont surtout des jeunes qui ont fait ce genre de constat. La présence de drogue est plus importante dans les pôles urbains que dans les communes rurales. Les consommateurs de drogue et les dealers, lorsqu’ils sont « souvent » présents dans le quartier, ont un effet anxiogène sur la population : certaines personnes sortent moins souvent la nuit et évitent de passer à des endroits ou d’emprunter des rues. Certaines personnes se sentent également plus exposées au risque de vol à la tire, de vol avec violence et de cambriolage. Par contre, lorsque ces rencontres avec des consommateurs ou des revendeurs de drogue sont plus exceptionnelles, celles-ci ne semblent pas jouer, ou très peu, sur le sentiment d’insécurité de la population.

In this write-up of a talk presented at the Bia\l owie\.za meetings we report on results on Lie superalgebras of Krichever-Novikov type. These algebras are multi-point and higher genus equivalents of the classical algebras. The grading in the classical case is replaced by an almost-grading. It is induced by a splitting of the set of points, were poles are allowed, into two disjoint subsets. With respect to a fixed splitting, or equivalently with respect to a fixed almost-grading, it is shown that there is up to rescaling and equivalence a unique non-trivial central extension of the Lie superalgebra of Krichever--Novikov type.

[more ▼]The paper introduces an additional channel via which corruption may adversely affect environmental quality. It is argued that, in the presence of corruption, politicians may allocate a large fraction of public funds to environmental projects aiming not at improving environmental quality, but rather at increasing their ability to extract rents. This type of behavior has a direct and an indirect effect on environmental quality. First, due to extensive rent-seeking, the effectiveness of environmental projects is disproportional to the amount of public funds allocated to them. Second, citizens who observe the poor outcome of environmental projects, increase tax evasion thus reducing public funds. A vicious circle of extensive tax evasion and rent seeking activities emerges, that has a detrimental effect on environmental quality. Anecdotal evidence from a number of countries that experience high levels of corruption, shows little or no improvements in environmental quality despite the implementation of environmental projects. In line with our theoretical findings, this ineffectiveness of the environmental policy is present even when the technology involved is advanced.

[more ▼]This paper tests the theoretically founded hypothesis that the surge of SWF establishments is determined by three main factors: 1) the existence of natural resources profits, 2) the government structure and 3) the ability to invest usefully in the domestic economy. We test this hypothesis on a sample of 20 countries that established an SWF in the period 1998-2008 by comparing them to the roughly 100 countries that did not set up a fund in the same period. We find evidence for all three factors. The results suggest that SWFs tend to be established in countries that run an autocratic regime and have difficulties finding suitable opportunities for domestic investments. We do not find the net foreign asset position of a country to be similarly related to the explanatory variables, indicating that the establishment of an SWF is distinct from a national accounting result. We argue that our results indicate that it is relevant to study how an SWF interacts with the domestic economy and government policy.

We use unique administrative records of workers to estimate distributions of future pensions for the actual and multi-pillar system and assess the effects on pension inequality, pension liability and overall welfare for the insured population. Our results show that the large pension inequality and liability of the actual pension system can be substantially reduced with welfare preserving policies. As we consider different types of social welfare functions, our simulations illustrate, that when one considers welfare, it is important to define the implied value judgments, which are not universally agreed upon. Thus, the goal of this study is not to advice for a particular scenario of reform, but highlight the trade-offs that have to be made explicit in order to take the best possible option, which can be useful for policy-makers who intend to carry out a next generation of pension reforms in Latin America in the near future.

Methodologi-cally, the project incorporates interactive workshops and Delphi-based feedback and validation rounds, that – over the lifespan of the project – offer a mutual learning process further inspired by in-sights and experiences across four case studies in Europe, Australia, and Canada. The exchange and learning processes provide important insights on different forms and pathways of sustainability transi-tions in the building sector to all participants involved in the project, researchers and researched alike.

[more ▼]70% des résidents pensent que la vidéo-surveillance des lieux publics au Luxembourg augmente leur sécurité personnelle, 23% pensent qu’elle n’a pas d’impact et 3% sont même d’avis que la vidéosurveillance diminue leur propre sécurité. Les personnes qui craignent d’être agressées physiquement ou qui sont inquiètes d‘être victimes d'une attaque terroriste, celles qui trouvent probable d’être victime d’un cambriolage ou d’un vol avec violence, celles qui ne se sentent pas en sécurité dans leur quartier de résidence et celles qui sont d’avis que la criminalité au Luxembourg a progressé au cours des dernières années, s’attendent plutôt à une augmentation de leur sécurité par les systèmes de surveillance sur certains lieux publics. Par contre les résidents qui effectivement ont été victimes d’un délit ou ceux qui sont confrontés à des problèmes de drogues dans leur quartier résidentiel, ont des doutes quant à l’efficacité de la vidéo-surveillance. Les jeunes sont les plus sceptiques. Par ailleurs, 27% des logements sont équipés d’un système d'alarme et 57% ont des portes de sécurité. On retrouve plus souvent ces deux mesures de sécurité dans les maisons unifamiliales que dans les maisons en rangée ou dans les appartements. En outre, la présence de systèmes d'alarme et de portes de sécurité est fortement liée au revenu du ménage. Quant à la possession d'armes à feu en tant que mesure de sécurité elle joue un rôle mineur : seulement 6% des répondants ont déclaré posséder des armes à feu et parmi eux un-tiers évoquent la prévention et la protection contre les crimes pour justifier la présence d’armes à feu chez eux.

STAR stands for “Sociolinguistic trajectories and repertoires: Luso-Luxo-African identifications, interactions and imaginations”, and is a 3-year CORE research project funded by FNR, Luxembourg. The multi-sited project, meant as contribution to the field of sociolinguistics of globalization, investigates language and migration between the global South (Cape Verde and Guinea Bissau) and North (Luxembourg) from the perspective of both accomplished and desired migrants. In this first research brief we review literature on flows of migration from West Africa.

[more ▼]We provide empirical support and a theoretical explanation for the vicious circle of political corruption and tax evasion in which countries often fall into. We address this issue in the context of a model with two distinct groups of agents: citizens and politicians. Citizens decide the fraction of their income for which they evade taxes. Politicians decide the fraction of the public budget that they peculate. We show that multiple self-fulfilling equilibria with different levels of corruption can emerge based on the existence of strategic complementarities, indicating that corruption may corrupt. Furthermore, we find that standard deterrence policies cannot eliminate multiplicity. Instead, policies that impose a strong moral cost on tax evaders and corrupt politicians can lead to a unique equilibrium.

[more ▼]This paper assesses whether the European legislative reform on the protection of personal data, in conjunction with national law, responds in a satisfactory manner to the challenges posed by technological evolution and widespread use of Internet. In recent years, the question of State regulation of the processing of personal data by private companies has become urgent as allegations of unauthorized access to personal data have been hotly debated in the European press. Thus, the paper shall first analyse, the appropriateness of European and States' legislation to properly regulate the effective protection of personal data, in particular of obligations applicable to companies storing and processing personal data on European soil. Does the proposed European legislation in the context of the EU's international agreements with the US provide sufficient legal safeguards to ensure the effective protection of personal data in the post-Snowden era? Specific subparts are devoted to the European reform of companies' criminal liability in cases of cyber-attack (a) and of specific obligations imposed on providers of cloud computing services (b). In the second part, I comment on the interpretation of the European data-protection legislation, provided by the Court of Justice, regarding the obligations imposed upon 'intermediaries' that process personal data, such as the Internet service providers (a) and Internet search engines (b). The Court of Justice has interpreted the European legislation in a manner that allows courts and national authorities to impose on companies a set of safeguards to protect individuals against the infringement of copyright and privacy rights.

[more ▼]We develop a model where workers both choose their residential location (geographical space) and social interactions (social space). In equilibrium, we show under which condition the majority group resides close to the job center while the minority group lives far away from it. Even though the two populations are ex ante totally identical, we find that the majority group experiences a lower unemployment rate than the minority group and tends to socially interact more with other workers of its own group. Within each group, we demonstrate that workers residing farther away from the job center tend to search less for a job and are less likely to be employed. This model is thus able to explain why ethnic minorities are segregated in the urban and social space and why this leads to adverse labor-market outcomes in the absence of any discrimination against the minority group.

[more ▼]86% de la population estiment que la Police Grand-Ducale réalise du « bon », voire du « très bon » travail. L’évaluation du travail de la police est ainsi légèrement meilleure que pour les tribunaux. En effet, concernant les tribunaux, 75% de la population trouvent qu’ils effectuent du « (très) bon » travail. Une différence existe dans l’appréciation du travail de la police chez les personnes victimes et non-victimes. Parmi les personnes qui n’ont été victimes d’aucun des 14 délits pris en compte par l’enquête au cours des 5 dernières années, 91% sont d’avis que la police fait du « (très) bon » travail. Les victimes, elles, sont 82% à partager cet avis. L’évaluation varie selon la nature et le lieu du délit dont les résidents ont été victimes. 88% des victimes d’un délit ayant eu lieu à l’étranger jugent comme « (très) bon » le travail policier. Ce chiffre descend à 79% pour les victimes de délits qui se sont produits sur le territoire national. Concernant la nature du délit, les victimes de délits sans violence ont une meilleure opinion du travail de la police que les victimes de délits avec violence (82% contre 71%). 89% des victimes qui ont rapporté le délit à la police et qui ont été « très satisfaits » par la manière dont leur affaire personnelle a été traitée pensent que le travail de la Police Grand-Ducale est « (très) bon ». Si par contre les victimes étaient « très insatisfaits » par le traitement de leur dossier, ils sont moins enclins (45%) à évaluer comme « (très) bon » le travail de la police.

[more ▼]In this paper, we construct hybrid T-Trefftz polygonal finite elements. The displacement field within the polygon is repre- sented by the homogeneous solution to the governing differential equation, also called as the T-complete set. On the boundary of the polygon, a conforming displacement field is independently defined to enforce continuity of the displacements across the element boundary. An optimal number of T-complete functions are chosen based on the number of nodes of the polygon and degrees of freedom per node. The stiffness matrix is computed by the hybrid formulation with auxiliary displacement frame. Results from the numerical studies presented for a few benchmark problems in the context of linear elasticity shows that the proposed method yield highly accurate results.

[more ▼]This paper analyses gender differences on cognitive abilities for the elderly poor in Peru. We use a unique and recent survey for the elderly individuals living in poverty in Peru (ESBAM) that includes cognitive tests and a comprehensive set of socio-demographics and subjective and objective health measures. We find significant differences in mental intactness in favour of males, and in episodic memory in favour of females. In contrast, there are not gender differences in an overall measure of cognition, but regional differences appear to matter in favour of urban localities. The sizeable associations of education and childhood nutrition quality with cognition confirm the long-term impacts of early life developments on current outcomes. Therefore, policies aimed at improving early childhood development are expected to have a positive impact in later-life.

[more ▼]This study investigated the determinants of Successful Ageing (SA) in a sample of 4,151 Peruvians aged between 65 and 80 and living in poverty. The data correspond to the ESBAM survey, which is the baseline to evaluate the non-contributory public pension program Pension 65. A key contribution of this study is to combine the conceptual appealing of Successful Ageing to measure well-being in old-age with the multidimensional poverty counting approach developed in the economic literature. This setting allows for moving beyond the dichotomy of the SA literature (success or usual ageing) and take advantage of the full distribution of success along the set of dimensions of well-being. Nine indicators of SA have been used to assess the dimensions of physical health, functioning, cognition, emotional health, and life satisfaction. The variables associated with a higher number of satisfied indicators were being a male, younger, literate, working, low food insecurity, good nutritional status, normal blood pressure, absence of disabilities, not smoking, empowerment, good self-esteem, absence of mental disability, and less frequent contact with a social network. From a policy perspective, the results of this study report a remarkably stable effect of three variables affecting SA that can be relatively easy to measure, monitor and affect by public intervention. These variables are food security, nutrition quality, and self-esteem.
