[more ▼]We scrutinize Thomas Piketty’s (2014) theory concerning the relationship between an economy’s long-run growth rate, its capital-income ratio, and its factor income distribution put forth in his recent book Capital in the Twenty-First Century. We find that a smaller long-run growth rate may be associated with a smaller capital-income ratio. Hence, the key implication of Piketty’s Second Fundamental Law of Capitalism does not hold. In line with Piketty’s theory a smaller long-run growth rate may go together with a greater capital share. However, the mechanics behind this result are the opposite of what Piketty suggests. Our findings obtain in variants of Romer’s (1990) seminal model of endogenous technological change. Here, both the economy’s savings rate and its growth rate are endogenous variables whereas in Piketty’s theory they are both exogenous parameters. Including demographic growth in the spirit of Jones (1995) shows that a smaller growth rate of the economy may imply a lower capital share contradicting a central claim in Piketty’s book.

[more ▼]This research empirically establishes and theoretically motivates the hypothesis that population aging has a hump-shaped effect on inventive activity. We estimate this hump-shaped relationship in a panel of 33 OECD countries over the period 1960-2012. The increasing part of the hump captures the awareness that population aging requires inventive activity to guarantee current and future standards of living. The decreasing part reflects the tendency of aging societies to lose dynamism and the willingness to take risks. Policy-wise our analysis suggests that raising the awareness of individuals about the consequences of population aging may facilitate the adoption of strategies and policies encouraging inventive activity and economic growth.

[more ▼]In the present paper, we introduce the Finite Difference Method-Meshless Method (FDM-MM) in the context of geodynamical simulations. The proposed numerical scheme relies on the well-established FD method along with the newly developed “meshless” method and, is considered as a hybrid Eulerian/Lagrangian scheme. Mass, momentum, and energy equations are solved using an FDM method, while material properties are distributed over a set of markers (particles), which represent the spatial domain, with the solution interpolated back to the Eulerian grid. The proposed scheme is capable of solving flow equations (Stokes flow) in uniform geometries with particles, “sprinkled” in the spatial domain and is used to solve convection- diffusion problems avoiding the oscillation produced in the Eulerian approach. The resulting algebraic linear systems were solved using direct solvers. Our hybrid approach can capture sharp variations of stresses and thermal gradients in problems with a strongly variable viscosity and thermal conductivity as demonstrated through various benchmarking test cases. The present hybrid approach allows for the accurate calculation of fine thermal structures, offering local type adaptivity through the flexibility of the particle method.

They play a very important role in the context of quantization of Conformal Field Theory. In this review we give the most important results about their structure, almost-grading and central extensions. Furthermore, we explain how they are used in the context of Wess--Zumino--Novikov--Witten models, respectively Knizhnik-Zamolodchikov connections. There they play a role as gauge algebras, as tangent directions to the moduli spaces, and as Sugawara operators.

[more ▼]We introduce a fast and widely applicable numerical pricing method that uses recursive projections. We characterize its convergence speed. We find that the early exercise boundary of an American call option on a discrete dividend paying stock is higher under the Merton and Heston models than under the Black-Scholes model, as opposed to the continuous dividend case. A large database of call options on stocks with quarterly dividends shows that adding stochastic volatility and jumps to the Black-Scholes benchmark reduces the amount foregone by call holders failing to optimally exercise by 25%. Transaction fees cannot fully explain the suboptimal behavior.

[more ▼]This paper studies pension insecurity in a sample of non-retired individuals aged 50 years or older from 18 European countries. We relate pension insecurity with the subjective expectations on the probability that the government will reduce the pensions of the individual before retirement or will increase the statutory retirement age. We argue that changes in economic conditions and policy affect the formation of such probabilities, and through this, subjective wellbeing. In particular, we study the effects of pension insecurity on subjective wellbeing with pooled OLS models, regressions per quintiles and instrumental variables. We find a statistically significant, stable and negative association between pension insecurity and subjective wellbeing. The quintile regressions allow us to establish that pension insecurity is more salient for individuals who are poorer, who subjectively assess their life survival rate as low and who have higher cognitive abilities.

[more ▼]The goal of this paper is to study and explain the differences in wellbeing in old age across cohorts and countries in Europe. This is done with the replication of the Active Ageing Index for cohorts formed by age group, sex and country for 2012. The analysis is performed with different model regressions at the cohort level and introducing macro variables at the country level. In general, there is a gap in active ageing in detriment of females which is larger in older cohorts. In addition, wealth, equity and pension settings of the country are important predictors for better active ageing. Finally, it is found that the Social-Democratic welfare regime (Nordic countries) with its set of strong redistributive policies, is the most favourable system for active ageing.

[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.

[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 ▼]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.

We find that providing medical equipment to a random sample of Ugandan adults with lower limb disabilities has a positive effect on their physical health, using both objective and self-reported measures. Treated patients experience a significant improvement in life satisfaction initially, but the effect is not prolonged. After one year, life satisfaction returns to the pre-treatment level, supporting the hypothesis of adaptation. This evidence of adaptation is supported by observations of changes in aspirations and expectations and is robust to alternative estimation methods including instrumental variable estimation and ITT analysis.

[more ▼]“Je t’aime, moi non plus” : this is how the French newspaper L’Express (2011, p. II) summarises the transnational linkages of Luxembourg with its neighbouring countries. On the one hand, the ‘economic engine’ Luxembourg offers workplaces for many commuters, positively affecting the development of this European cross-border polycentric metropolitan region; on the other hand, negative consequences such as the overcrowded real estate mar-ket in Luxembourg continue beyond the national border and affect neighbouring housing markets. The ‘2020 Concept for the Region Trier’ shows that city councils perceive the prox-imity to Luxembourg as an opportunity for the development of the city. Simultaneously, lo-cals might feel displaced due to increasing rents and house prices, and develop resentment vis-à-vis their new neighbours, coming either from Luxembourg, or being Belgian, German or French nationals (labour migrants) that have moved to the border region to work in the Grand Duchy of Luxembourg, thus disposing of higher purchase power. Depending on the context, similar effects can thus be perceived very differently by city councils or planners and the local population. So far, studies dealing with the processes of transmigration have mostly focussed on indi-vidual motives of migrants, whereas impacts on the regions of destination have not been explored. The aim of this study is to explore ongoing discourses dealing with spatial impacts in relation to urban housing markets within the Greater Region. The focus will be on the cit-ies Arlon (BE), Metz and Thionville (FR), and Trier (DE). Therefore mixed methods will be de-ployed. Firstly, a quantitative analysis is planned to reveal the magnitude and the spatial distribution of the (cross-border) residential mobility. The evolution of housing prices and rents as well as population dynamics will be examined. Secondly, ongoing discourses and the changes of life-worlds will be studied using quantitative methods as well as qualitative methods, such as content analysis, to review the guiding principles of municipal policy and urban planning documents. A quantitative analysis of local newspapers will be conducted to analyse public opinion. A content analysis of this material will follow. The method mix allows us to better understand “material” evolutions and to trace the current discourses within this field. Discourse approaches have become common in interdis-ciplinary social science academic research. However, there are no established theoretical and methodological guidelines for applying these approaches. This project has to deal with this situation and to take into account different cultural backgrounds and discussion levels. This study will help to frame today’s situation and aims to develop sustainable solutions for future urban planning.

[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.

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.

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.

[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 ▼]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 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.

[more ▼]This paper investigates the dynamics of hedge fund returns and their behavior of persistence in a unified framework through the Markov Switching ARFIMA model of Härdle and Tsay (2009). Major results based on the CSFB/Tremont hedge fund indexes monthly data during the period 1994-2012, highlight the importance of the long memory parameter magnitude i.e shocks in shaping hedge fund return dynamics and show that the hedge fund dynamics are characterized by two levels of persistence: in the first one, associated to low-volatility regime, hedge fund returns are a stationary long memory process whereas in the second one, associated to high-volatility regime, returns exhibit higher parameter of fractional integration. More precisely, in high volatility regime i.e periods of turmoil, the process tends to be non-stationary but still exhibits a mean-reverting behavior. The findings are interesting and enable us to establish a relationship between hedge fund return states and memory phenomenon.

[more ▼]We examine the transmission of extreme stock market returns among three groups of countries: the Euro-periphery countries (Portugal, Ireland, Italy, Greece, Spain), the Euro-core countries (Germany, France, the Netherlands, Finland, Belgium), and the major European Union -but not euro- countries (Sweden, UK, Poland, Czech Republic, Denmark). Using extreme returns on daily stock market data from January 2004 till March 2013, we nd that transmission e ects are present for the tails of the returns distributions for the Pre-crisis, the US-crisis and the Euro-crisis periods from the Euro-periphery group to the Non-Euro and the Euro-core groups. Within group e ects are stronger in the crisis periods. We nd that the transmission channel does not seem to have intensi ed during the crisis periods, but it transmitted larger shocks (in some cases, extreme bottom returns doubled during the crisis periods). Thus, as extreme returns have become much more "extreme" during the nancial crisis periods, the expected losses on extreme return days have increased signi cantly. Given the fact that stock market capitalisations in these country groups are trillions of Euros, a 1% or 2% increase in extreme bottom returns (in crisis periods) can lead to aggregate losses of tens of billions Euros in one single trading day.

[more ▼]This study proposes an efficient combination of the Discrete Element Method (DEM) and the Finite Element Method (FEM) to study the tractive performance of a rubber tire in interaction with granular terrain. The presented approach is relevant to all engineering devices interacting with granular matter which causes response forces. Herein, the extended discrete element method (XDEM) is used to describe the dynamics of the granular assembly. On the one hand, the discrete approach accounts for the motion and forces of each grain individually. On the other hand, the finite element method accurately predicts the deformations and stresses acting within the tire tread. Hence, the simulation domain occupied by the tire tread is efficiently described as a continuous entity. The coupling of both methods is based on the interface shared by the two spatially separated domains. Contact forces develop at the interface and propagate into each domain. The coupling method enables to capture both responses simultaneously and allows to sufficiently resolve the different length scales. Each grain in contact with the surface of the tire tread generates a contact force which it reacts on repulsively. The contact forces sum up over the tread surface and cause the tire tread to deform. The coupling method compensates quite naturally the shortages of both numerical methods. It further employs a fast contact detection algorithm to save valuable computation time. The proposed DEM-FEM Coupling technique was employed to study the tractive performance of a rubber tire with lug tread patterns in a soil bed. The contact forces at the tread surface are captured by 3D simulations for a tire slip of 5%. The simulations showed to accurately recapture the gross tractive effort, running resistance and drawbar pull of the tire tread in comparison to related measurements. Further, the traction mechanisms between the tire tread and the granular ground are studied by analysing the motion of the soil grains and the deformation of the tread.

[more ▼]We empirically investigate and evaluate various approaches to structurally assess credit risk changes using a panel of selected European banking groups. The objective is to evaluate the models according to one metric, i.e., their ability to correctly and timely identify changes in credit risk indicators useful for macroprudential policy. We consider not only the standard approaches in the literature, but also include models that allow the asset volatility to be stochastic and models that allow for short- and long-term components of default risk. Surprisingly, we find that the GARCH structural credit risk model, despite its more sophisticated modeling approach, typically underperforms more basic models. Importantly for macro-prudential policy, combining the Merton model with the GARCH-MIDAS model performs best and reflects important market events earlier than the other approaches.

The empirical evidence presented in the paper provides strong confirmation of this prediction.

On the contrary, a model with imperfectly competitive labor market allows to consider as well the effects of a drop in bargaining power, which would not be possible in a purely neoclassical framework. We find that a decline in the bargaining power of workers, which has taken place in the last four decades, has largely contributed to the rise in inactivity in Europe. However, we need a combination of these two explanations, along with population aging and a fall in the matching efficiency, in order to correctly reproduce the joint evolutions of other labor market variables such as the employment and unemployment rates.
