With 201,785 cross-border employees, the Grande Région has a quarter of the cross-border workers in the 27 EU countries. 73% of cross-border commuters in the Grande Région work in Luxembourg, where they account for 44% of the local workforce - a trend that is still rising. Half of them come from France and about a quarter from Belgium or Germany. 14% of cross-border commuters in the Greater Region work in Wallonia, almost all of them from France. Finally, Saarland is the third largest employer of cross-border workers, with almost 10% of border workers in the Greater Region. Among the "French" workers coming to work in Saarland, however, there is a third of atypical cross-border workers, i.e. Germans who live in Lorraine and work in Saarland. [less ▲]

In this paper we investigate the construction of bicategories of fractions originally described by D. Pronk: given any bicategory C together with a suitable class of morphisms W, one can construct a bicategory C[W^{-1}], where all the morphisms of W are turned into internal equivalences, and that is universal with respect to this property. Most of the descriptions leading to such a construction were long and heavily based on the axiom of choice. In this paper we simplify considerably the constructions of associators, vertical and horizontal compositions in a bicategory of fractions, thus proving that the axiom of choice is not needed under certain conditions. The simplified description of associators and 2-compositions will also play a crucial role in the next papers of this series. [less ▲]

The homomorphism order of graphs is known to be dense with a single exception.

Moreover, every antichain included in such an interval can be extended into an infinite one within that interval. [less ▲]

Using an optimal changepoint approach, we find a structural change in the relation between hedge funds’ stock market exposure and aggregate stock market liquidity that takes place in the period 2000 to 2002. Before the structural break, market betas have no relation to liquidity and only a few style categories of hedge funds show increased market presence when liquidity is low. After the break, the relationship is inverted, pointing towards an increased liquidity timing ability of hedge funds, as users of liquidity. We relate our findings to best execution rules and decimalization in the US stock market that were introduced in that period and impacted aggregate liquidity conditions. Furthermore, the returns to a momentum strategy display a similar structural break and momentum-loading funds constitute a sizeable proportion of hedge funds that manifest a distinct beta-liquidity evolution with a structural break in that period.

In this paper, we analyze optimal foreign direct investment of a firm which operates in a duopolistic market. We characterize a technology spillover threshold and show that for an intensity of spillovers below this threshold, there is a unique locally asymptotic stable steady state with a positive capital stock in the developing country. Furthermore, we characterize how optimal foreign investment patterns and the investor’s value function depend on the level of technology transferred and characterize the optimal level to be used for the foreign direct investment.

The debate regarding the economic effects of immigration has attracted renewed interest in European countries since the economic crisis. We provide an approximation for the labor market effects of immigrants in four European countries during the global economic crisis after briefly analyzing the situation of native- and foreign-born workers for the recent period. Our analysis focuses on the correlation between the stock of immigrant workers and the number of local labor market workers across several segments of the labor market using a simple model approach. Based on data from Eurostat and the LFS (Labour Force Survey), we estimate a structural dynamic model using the Generalized Method of Moments (GMM) to take into account the adjustment dynamics in the labor market and labor market segment, educational level, country of origin and gender of the workers. Overall, the empirical results suggest that the immigration shock on the employment rates of native-born workers is persistent and very weak over the business cycle. The effect is globally positive and the origin of immigrants does not appear to change the nature of the impact. We offer some explanations for these findings that are linked with the dual labor markets and the differences in the degree of substitution between native and immigrant workers. [less ▲]

This paper investigates the theoretical effects of immigration in an occupational choice model with three sectors: a low-skilled, a high-skilled and a public sector. The originality of our approach is to consider (i) intersectoral mobility of labor and (ii) public employment. We highlight the fact that including a public sector is crucial, since omitting it implies that low-skilled immigration unambiguously reduces wages and welfare of all workers. However, when public employment is considered, we demonstrate that immigration increases wages in the high-skilled and the public sectors, provided that the immigrant workforce is not too large and the access to public jobs is not too easy. The average wage of natives may also increase accordingly. Moreover, immigration may improve workers’ welfare in each sector. Finally, the mechanism underlying these results does not require complementarity between natives and immigrants. [less ▲]

One family of heterogeneous strategies in differential games with (a)symmetric players is developed in which one player adopts an anticipating open-loop strategy and the other adopts a standard Markovian strategy. Via conjecturing principle, the anticipating open-loop strategic player plans his strategy based on the possible updating the rival player may take. These asymmetric strategies frame nondegenerate Markovian Nash Equilibrium, which can be subgame perfect. Except the stationary path, this kind of strategy makes the study of short-run trajectory possible, which usually are not subgame perfect. However, the short-run nonperfection provides very important policy suggestions. [less ▲]

This note studies the stochastic stability of the standard AK growth model un- der uncertain output technology. Capital accumulation follows a stochastic lin- ear homogenous differential equation. It’s shown that exponential balanced paths, which characterize optimal trajectories in the absence of uncertainty, are not robust to uncertainty. Precisely, it’s demonstrated that the economy almost surely col- lapses at exponential speed even though productivity is initially arbitrarily high. [less ▲]

We prove the existence of a unique maximal surface in an anti-de Sitter (AdS) convex Globally Hyperbolic Maximal (GHM) manifold with particles (i.e. with conical singularities along timelike lines) for cone-angles less than $\pi$.

L’exploitation des résultats est réalisée conjointement par le STATEC et l’Université du Luxembourg/INSIDE (Integrative Research Unit on Social and Individual Development). L’enquête couvre différents types de « délits ». Les délits pris en compte sont les délits dont les résidents de 16 ans ou plus ont été victimes entre 2008 et 2013, mais pouvant avoir eu lieu dans un autre pays. De plus, ces délits reprennent les faits déclarés à la police, mais également tous les délits qui n’ont pas fait l’objet d’une plainte. Les données récoltées permettent ainsi d’apporter un nouveau regard sur les données de la criminalité au Luxembourg. [less ▲]

C’est à partir de 15 ans que commence la transition des jeunes de l’éducation vers le marché du travail. Cette phase de transition se clôt vers l’âge de 30 ans. À l’âge de 29 ans, 83.7% des jeunes adultes ont un emploi, 4.1% sont occupés dans leur propre ménage et seulement 3.2% suivent encore une formation. Chez les 25-29 ans, la part des chômeurs est d’autant plus élevée que le niveau d’éducation est faible. De même, dans cette tranche d’âge, les personnes ayant un niveau d’éducation faible travaillent plus souvent dans leur propre ménage. Parmi les jeunes qui ont un emploi, la part des contrats de travail à durée déterminée (CDD) diminue avec l’âge : chez les personnes âgées de 21 ans, la part des CDD est de 23.9 % ; elle recule à 9.9% chez les personnes âgées de 29 ans. 32.2% de l’ensemble des jeunes âgés de 15 à 29 ans et ayant un emploi travaillent dans la branche « administration publique, éducation, santé et action sociale ». En revanche, le pourcentage correspondant n’est que de 0.9% dans l’agriculture. La part des femmes âgées de 15 à 29 ans est la pIus importante dans la branche des « autres services » (74.9%) qui inclut notamment les activités des ménages en tant qu’employeurs et donc les femmes de ménage. Les femmes sont peu représentées dans la construction (9.7%). Les étrangers de 15 à 29 ans sont surrepré-sentés dans la construction, mais également dans les « activités spécialisées, scientifiques et techniques et activités de services administratifs et de soutien » (environ 65% dans ces deux branches). En revanche, les étrangers sont sous-représentés dans la branche « administration publique, éducation et santé et action sociale » (14.7% de l’emploi des 15-29 ans dans cette branche), ainsi que dans l’agriculture (13.3%). Avec 46.9%, près de la moitié des jeunes de nationalité luxembourgeoise travaillent dans le secteur public et parapublic (administration publique, éducation, santé et action sociale). La répartition des jeunes étrangers sur les différentes branches d’activité est plus équilibrée. [less ▲]

We examine the existence of stock market contagion effects 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 daily stock market data from January 2004 till March 2013, contagion effects for the tails of the marginal distributions are present for the Pre-crisis and the Euro-crisis periods within the Euro-periphery countries and from the Euro-periphery group to the Non-Euro and the Euro-core groups. We do not find a significant change in the contagion transmission mechanism when comparing the two periods, but for the Euro-crisis periods the extreme returns have a higher magnitude. Finally, we propose a connection between extreme stock market returns, the Web Attention index and two News Flow factors. The Euro-periphery Web Attention and News Flow variables significantly affect the probabilities of extreme bottom returns for the Euro-periphery, the Non-euro and the Euro-core groups. The effect is asymmetric in most of the cases since the Euro-periphery Web Attention and News Flow factors do not affect the probabilities of extreme top returns, with a few exceptions. More Web Attention and more bad news for the Euro-periphery in times of crisis are associated with higher probabilities of extreme bottom returns within and across groups. Granger-causality tests show that the News Pessimism and the News Relevance factors exhibit a two-way causality with the stock market movements while the Web Search Volume Index (SVI) one-way Granger-causes stock markets and extreme bottom returns in the three country groups.

Am 1. Februar 2011 lebten 71 742 Menschen über 64 Jahre in Luxemburg, was einem Anstieg von +17.5% im Vergleich zur Volkszählung 2001 entspricht. Verglichen mit dem Wachstum der Gesamtbevölkerung von 16.6% ist die Zahl der älteren Menschen somit etwas stärker gewachsen. Der Ausländeranteil ist bei den älteren Menschen deutlich niedriger als in der Gesamtbevölkerung (21.4% vs. 43.0%). Allerdings ist der Ausländeranteil in dieser Bevölkerungsgruppe seit der Volkszählung 2001 gestiegen (damals 15.3%). Die höhere Lebenserwartung von Frauen zeigt sich darin, dass der Frauenanteil mit zunehmendem Alter ansteigt: Bei den über 64-Jährigen liegt der Frauenanteil bei 57.2%, bei den über 84-Jährigen bei 73.2%. Damit geht einher, dass es für Frauen deutlich wahrscheinlicher ist, dass ihr Partner vor ihnen stirbt. Frauen sind damit mit einer höheren Wahrscheinlichkeit im Alter alleinstehend, leben bei ihren Kindern oder ziehen in ein Pflegeheim. Umgekehrt ist es für Männer deutlich wahrscheinlicher, dass sie auch im höheren Alter noch mit ihrer Partnerin im Privathaushalt zusammenleben. [less ▲]

De 2001 à 2011, le nombre d’enfants et de jeunes âgés de moins de 20 ans est passé de 107 930 à 119 173, soit une augmentation de 10.4%. Comme la population totale s’est accrue plus fortement (+16.6% entre 2001 et 2011), la part des moins de 20 ans dans la population a diminué légèrement, de 24.6% en 2001 à 23.3% en 2011. Chez les Italiens résidant au Luxembourg, le pourcentage correspondant est particulièrement faible : 13.4% des Italiens ont moins de 20 ans. En revanche, 43.2% des Monténégrins résidant au Luxembourg ont moins de 20 ans. 99.2 % des enfants et des jeunes de moins de 20 ans vivent dans des ménages privés (par opposition à des ménages collectifs, comme les foyers).

À l’âge de 25 ans, 55.8% des jeunes ne vivent plus avec leurs parents. Chez les étrangers, à 25 ans, la part de ceux qui n’habitent plus avec leurs parents est plus élevée que cette moyenne (74.8%), alors que, pour les Luxembourgeois, la part est plus faible (39.6%).

This paper analyses the effect of antidumping (AD) duties on the pricing behaviour of exporters targeted with these measures. Using product and firm-level data for South Korea, the study provides evidence of increased export unit values and firms’ markups following the imposition of AD ad valorem duties. These findings are consistent with the hypothesis that, unlike other import tariffs, AD duties are not absorbed by exporters. The results on firms’ average markups also suggest that the price adjustment following the imposition of AD duties occurs mostly through the export price, and not through reductions in the exporter’s home price. The analysis controls for the presence of other trade measures as well as the endogeneity in AD and other contingent protection measures. [less ▲]

À la date du recensement au 1er février 2011, 148 812 personnes vivaient dans la région sud du pays, soit une augmentation de 12.3% par rapport au recensement de 2001. Cette augmentation de la population est inférieure à la moyenne nationale (+16.6%). La structure par âge de la population de la région sud est assez proche de celle du pays dans son ensemble. On note néanmoins des différences significatives entre Luxembourgeois et étrangers. Les Luxembourgeois sont surreprésentés dans les cohortes âgées et parmi les jeunes adultes. En re-vanche, les étrangers sont surreprésentés parmi les enfants et, surtout, dans les cohortes d’âge moyen de 25 à 50 ans. 58.9% des habitants de la région sud sont luxembourgeois et 23.1% sont portugais. Le pourcentage des personnes de toutes les autres nationalités présentes atteint 18% de la population. Avec 41.1%, la part globale des étrangers dans la population de la région sud est un peu inférieure à la moyenne nationale (43.0% d’étrangers). La part des propriétaires de logement est de 76% dans la région sud, soit un pourcentage légèrement supé-rieur à la moyenne nationale (73.0%). En revanche, la surface moyenne de logement est plus réduite dans la région sud que dans le pays dans son en-semble (117 m², contre 130 m²). Le loyer moyen est de 727 € dans la région sud, alors qu’il est de 888 € dans le pays. En revanche, comme les surfaces louées sont plus réduites qu’en moyenne nationale, le loyer par mètre carré ne se situe pas très loin de la moyenne du Grand-Duché (11.86 €/m² dans la région sud, contre 12.45 €/m² dans le pays dans son ensemble). Quant aux types de ménages, les diffé-rences entre la région sud et le pays dans son en-semble sont peu significatives. En revanche, on constate des écarts importants quant au niveau d’éducation. 45.5% de la population de la région sud ont un niveau d’éducation faible (primaire, se-condaire inférieur). Le pourcentage correspondant n’est que de 34.5% en moyenne dans le pays. À l’inverse, la part des habitants de la région sud ayant un niveau d’éducation élevé (enseignement supérieur) est, avec 15.1%, largement inférieure à la moyenne nationale (27.1%). [less ▲]

22 349 personnes habitaient dans les communes de la Nordstad au moment du recensement (1er février 2011), soit 7.2% de plus qu’en 2001. Dans les quatre communes les moins peuplées et périphériques aux communes de Diekirch et Ettelbrück, la croissance démographique dépasse la moyenne de la Nordstad, alors que l’augmentation du nombre d’habitants à Ettelbrück (+6.6%) et à Diekirch (+4.1%) est plus faible que la moyenne. Globalement, l’augmentation de la population de la Nordstad (+7.2%) se situe en deçà de celle du pays dans son ensemble (+16.6%). La structure par âge de la population de la Nordstad correspond globalement à celle du Grand-Duché. Cependant, la présence de la caserne militaire à Diekirch fait que les hommes jeunes sont surreprésentés. Comparés aux étrangers, les Luxembourgeois sont surreprésentés dans les cohortes âgées, alors que les étrangers sont surreprésentés dans les cohortes d’âge moyen. 60.9% des habitants de la Nordstad sont des Luxembourgeois et 24.1% des Portugais. Toutes les autres nationalités représentent 15.0% des habitants. En ce qui concerne le logement (taux de propriétaires, surface moyenne de logement, taille des ménages), les situations dans la Nordstad et au Grand-Duché dans son ensemble sont comparables. En revanche, avec 737 € en moyenne, les loyers se situent largement en-dessous de la moyenne nationale (888 €). Quant au niveau d’éducation, on constate des différences significatives entre la Nordstad et le pays dans son ensemble. Si au Grand-Duché moins d’un tiers des habitants a un niveau d’éducation faible (34.5%), le pourcentage correspondant atteint 42.1% dans la Nordstad. À l’inverse, la part des habitants ayant atteint un niveau d’éducation élevé n’est que de 18.8% dans la Nordstad, contre 27.1% dans la population totale. [less ▲]

Parmi les 512 353 personnes recensées au 1er février 2011, 231 472 (soit 45.2%) vivent en couple. Ce pourcentage est un peu plus élevé pour les étrangers (47.6%) que pour les Luxembourgeois (43.4%). 88.1% des personnes vivant en couple sont mariées, 9.1% vivent en union consensuelle et 2.7% sont « pacsées ». Les Luxembourgeois sont un peu plus souvent mariés (89.1%) que les personnes de nationalité étrangère (86.9%), qui eux vivent plus souvent en union consensuelle avec respectivement 10.8% des étrangers et 7.8% des Luxembourgeois. Il existe une corrélation assez prononcée entre l’âge et le fait d’être marié, car seulement 45% des personnes âgées de 20 à 24 ans qui vivent en couple sont mariées, alors que presque la totalité des 65 ans et plus le sont (97.9%). Concernant la situation socio-économique des personnes vivant en couple, 59.5% ont un emploi tandis qu’environ un cinquième est à la retraite. Les personnes mariées ont plus souvent des enfants vivant dans le même noyau familial que les deux autres types d’union. En effet, 61.5% des personnes mariées ont des enfants vivant dans le même noyau familial contre respectivement 53.2% et 38.5% pour les personnes en union consensuelle ou pacsées. On dé-nombre au total 13.1% de couples mixtes (Luxembourgeois-étranger), 48.1% de couples formés par des Luxembourgeois et 38.8% de couples constitués par 2 étrangers. Une mixité plus prononcée est observée parmi les couples vivant en union consensuelle ou pacsés que parmi les couples mariés. Un cinquième de ces couples pacsés ou vivant en union consensuelle sont formés par une personne luxembourgeoise et une personne de nationalité étrangère (respectivement 19.2% et 20.7%). Ce pourcentage ne s’élève qu’à 12.1% pour les couples mariés. Parmi les couples où au moins une personne travaille, 4 sur 10 sont composés de deux personnes ayant le même statut dans l’emploi. Globalement, dans 27.8% des couples, on trouve au moins un des deux conjoints qui travaille dans le secteur public. [less ▲]

This paper provides theory and evidence on airline bag fees, offering insights into a real-world case of product unbundling. The theory predicts that an airline’s fares should fall when it introduces a bag fee, but that the full trip price (the bag fee plus the new fare) could either rise or fall. The empirical evidence presented in the paper provides strong confirmation of this prediction. The data also suggest that the average fare falls by less than the bag fee itself, so that the full price of a trip rises for passengers who choose to check bags. [less ▲]

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. [less ▲]

Les habitants de la capitale (95 058 au 1er février 2011) se répartissent sur 24 quartiers. Le quartier de Bonnevoie-Sud est le plus peuplé (11 279 habitants), alors que Pulvermühle ne compte que 333 habitants. Entre 2001 et 2011, c’est le quartier du Cents qui a connu la croissance démographique la plus importante (+72.2%), tandis que les quartiers de Pfaffenthal (-8.7%) et de Clausen (-10.8%) ont perdu des habitants. Dans l’ensemble des quartiers de la capitale, la part des étrangers a augmenté. C’est dans le quartier de la Gare que la part des étrangers est la plus élevée (81.6% en 2011). Au Cents elle est la plus faible avec 42.4%. Dans le quartier de la Gare, la surface moyenne des logements est la plus restreinte (69.5 m²), alors qu’elle atteint plus du double à Cessange (130.0 m²). Les habitants du Grund et du quartier de la Gare vivent très majoritairement en location (respectivement 71.5% et 74.7% de la population). En revanche, au Cents, la part des locataires n’est que de 19.4%. En termes absolus, les loyers sont les plus élevés au Cents (1 285€ en moyenne par logement sans charges) et les moins élevés à Pfaffenthal (756€). Cependant, l’augmentation du prix des loyers de 2001 à 2011 est particulièrement importante au Pfaffenthal (+94.9%), alors qu’au Cents le loyer moyen n’a augmenté que de 28.7%. La surface des logements loués varie fortement entre les quartiers. Rapportés à la surface, les loyers sont les plus élevés dans le quartier de la Gare (17.08€ par m²), à Clausen (16.33€ par m²) et dans le quartier de Neudorf (16.27€ par m²). Ils sont les plus faibles à Pfaffenthal (11.41€ par m²) et à Hamm (11.79€ par m2). Dans la « Ville Haute Centre » et dans le quartier de la Gare, la part des personnes vivant seules est la plus élevée (43%). À Hamm, la part des couples avec enfant(s) parmi les ménages est la plus élevée (51.9%). En ce qui concerne le niveau d’éducation, c’est au Pfaffenthal que la part des personnes ayant un niveau d’éducation faible est la plus importante (53.0%), alors qu’au Limpertsberg le taux correspondant n’est que de 11.7%. Par contre, 67.5% des habitants du Limpertsberg ont atteint un niveau d’éducation élevé. [less ▲]

95 058 personnes vivaient dans la capitale à la date du recensement (1er février 2011), soit 24.0% de plus qu’en 2001. Avec ce taux, la croissance démographique de la Ville de Luxembourg a dépassé celle de sa périphérie, c’est-à-dire Luxembourg-Campagne1 (dont la population a augmenté de 17.0% de 2001 à 2011), mais aussi celle de l’ensemble du pays (+16.6%). Luxembourg-Ville et Luxembourg-Campagne représentaient ensemble 29.6% des habitants du pays en 2011, contre 28.4% en 2001. Seul un tiers des habitants de la capitale sont des Luxembourgeois (35.1%), suivis par les Français (14.3%) et les Portugais (14.1%). La sur-face moyenne des logements dans la Ville de Luxembourg est de 105.5 m² et se situe largement en-dessous de la surface moyenne des logements dans l’ensemble du pays (129.9 m²) et dans la périphérie de la Ville (144.8 m² à Luxembourg-Campagne). Cependant, la taille moyenne des ménages à Luxembourg-Ville (1.94 personnes par ménage) est également plus réduite que dans l’ensemble du pays (2.41) et à Luxembourg-Cam-pagne (2.47). Avec 26.4%, la part des habitants vivant seuls est près de deux fois plus élevée dans la capitale que dans le pays pris dans son en-semble (13.8%). 40.3% des habitants de la capitale vivent dans des ménages constitués par un couple avec enfant(s), alors que dans le pays le pourcen-tage correspondant atteint les 51.8%. Les habitants de la Ville de Luxembourg ont souvent des niveaux d‘éducation plus élevés que dans le reste du pays.

The present paper discusses the role of quality in patent examination process from the perspective of patent offices' behavior and organization. After documenting original stylized facts, the paper presents a model in which patent offices set patent fees and the quality level of their examination process. A higher effort in the examination process enhances the patent holders' protection in the judicial system and strengthens the screening of innovations with small inventive steps. We compare the quality of the examination process for various objectives of patent offices. Patent examination quality is the highest in an office maximizing incentives to innovate and the lowest in that maximizing the number of granted patents. A rent-seeking patent office can provide good incentives to innovate if it does not set too high markups on fees. [less ▲]

Previous research suggests that investor sentiment has an influence on the market's risk-return trade-off. Noise tradersídemand for assets is considered to be risk independent and, as a result, risky assets do not offer a risk premium when demand is high. We show that market risk is only a priced factor of expected fund returns when investor sentiment is low. Furthermore, fund investors seem aware that risk is sometimes not priced. During high sentiment periods, "smart" investors buy safe funds that subsequently outperform and sell risky funds that subsequently underperform. Our results are statistically and economically significant. [less ▲]

At the time of the census, 31,456 French lived in Luxembourg, or 6.1% of the total population. In absolute terms and as a percentage of the total population, these values ​​are the highest since the census of 1875. The average age of the French living in Luxembourg is, with 34.7 years, lower than that of the total population (38.7 years). Since the 2001 census, the number of French living in Luxembourg increased by 57.4%. This growth exceeds even that of the total of foreigners which has increased by 35.9% since 2001. 72% of French residents in 2011 arrived between 1995 and 2011, while the corresponding figure for this time period is only 56% for all immigrants. 73.4% of the French living in the country were born in France and 16.4% were born in the Grand Duchy. The French are the most numerous in Luxembourg City (13 450 people). Their relative share is also the highest in the capital, with 14.1% of the population of the City of Luxembourg.

On the occasion of the Portugal day, STATEC and the University of Luxembourg publish a portrait of the portuguese population living in Luxembourg, based on the results of the population census. On February 1st 2011 (Census Day), 82 363 Portuguese lived in Luxembourg, who make up 16.1% of the total population. Since 1970, the absolute number of Portuguese, as well as their share in the population increased continuously. The average age of the Portuguese is much lower than the average age of the total population (32.9 years against 38.7 years). 3 011 Portuguese living in Luxembourg are 65 years and older. This corresponds to only 3.7% of the total Portuguese population living in Luxembourg, whereas the proportion of persons aged 65 and over in the total population reached 14%. 70.0% of Portuguese living in Luxembourg were born in Portugal and 24.4% were born in Luxembourg. In absolute terms, most Portuguese (13 567) live in the City of Luxembourg. However, their relative share is the highest in Larochette (45.2% of the population of this municipality). On average, the Portuguese have a lower level of education than the total population. However, as for the total population, the level of education increased: the younger cohorts are better educated than older cohorts. Nevertheless, a gap remains. In the age group of 25 to 34 years, 50% of Portuguese people have a low level of education (primary and lower secondary), while the corresponding percentage is 20% for this age group in the total population. 53% of Portuguese living in the country in 2011 immigrated to Luxembourg between 1995 and 2011.

Avec 55.8%, la grande majorité des habitants du pays ont indiqué le luxembourgeois comme langue principale. Le portugais (15.7%) et le français (12.1%) suivent en deuxième et troisième position. Il existe un lien fort entre la nationalité et la langue principale : 88.8% des Luxembourgeois indiquent maîtriser le mieux la langue luxembourgeoise, ce taux est de seulement 8.0% pour les étrangers. Il est de 95.5% pour les Luxembourgeois de naissance et de 49.7% pour les Luxembourgeois par naturalisation. Le pays d'origine des parents a une influence sur la langue principale des Luxembourgeois de naissance de moins de 20 ans.

La présence du luxembourgeois comme langue principale est particulièrement marquée là où la proportion des étrangers est faible : à Consthum, le luxembourgeois est la langue principale de 83.9% des habitants alors que dans la ville de Luxembourg, cette proportion est de 35.2%.

Unter Rückgriff auf verschiedene Raumkonzepte wird zunächst ein handlungstheoretisches Verständnis von Raum vorgestellt und praxistheoretisch reformuliert. Es bildet den Ausgangspunkt zur Entwicklung des Modells Räume der Grenze mit seinen Analysekategorien soziale Praktiken, praktisches Wissen sowie physisch-materiale und sozial-strukturelle Aspekte.

In 2011, the Italians account only for 8.2% of the foreign citizens living in Luxembourg. In comparison with the general population, the Italians are much older on average (45.2 years for Italians, against 38.7 years on average for the total population). The majority of Italians living in Luxembourg was born in Italy (62.7%). 28.3% were born in Luxembourg. In absolute terms, most Italians live in the City of Luxembourg (5 750, nearly 30% of all Italians living in the Grand Duchy). However, their relative proportion in the population is the largest in Bertrange (7.0% of the population of the municipality, against 3.5% at the national level). Overall, the Italians have a lower level of formal education than the total population on average. However, young Italians have more often higher levels of education than people of the same age in the total population. [less ▲]

On the occasion of the International Day of Families, celebrated annually on May 15, STATEC and the University of Luxembourg / INSIDE (Integrative Research Unit on Social and Individual Development), publish the first results on the situation of households and families in the Grand Duchy of Luxembourg. Of the 512 353 people enumerated on February 1st 2011, 503 280 persons, or more than 98% live in private households and 2% in collective households. 83.4% of people living in private households are part of a family household, that is to say, a household in which at least two persons must be related. Nearly two-thirds of people live in households formed of only one couple with or without children, and 10% live in single-parent households. [less ▲]

We model intergenerational old-age support within the context of a developing country that faces demographic transition: declining fertility and increasing life expectancy. We attempt to answer if agents will be able to support their parents during the next generations and under what conditions. For this purpose we use a three period overlapping generations model and a cultural transmission process, in which agents may be socialized to different cultural family models (old-age supporters and non-supporters). As life expectancy increases, we find conditions under which a reduced fertility rate is compatible with the expectation to be supported during old-age. This offers an additional explanation for the persistency of family old-age support in developing countries facing demographic transsition. [less ▲]

This paper studies the dynamic correlation between stocks, between government bonds and between stocks and bonds within the Euro-zone in the last decade. In order to better understand the development of the financial market we argue that it is necessary to analyse all such relations simultaneously rather than focus at one. We firstly calculate the dynamic correlation for the previous asset classes. Results presented at the asset-region level, i.e. north-stock, north-bonds, south-stocks and south-bonds, visualise the divergence in integration in Europe and highlight the he- terogeneity in these markets. Secondly, we study the macroeconomic factors that determine these correlations. We find that, when we allow for regional division, not only cross-asset correlations within regions behave differently from each other, but also cross-assets cross-regions dynamic correlations can be explained with ma- croeconomic factors such as the relative market uncertainty between countries and balance of payments dynamics.

43,942 people counted in the Luxembourg 2011 census have immigrated from abroad to Luxembourg between 2005 and 2011. More than a third (34.1%) of these immigrants settled in the City of Luxembourg. During the same period 65,627 people migrated from one municipality to another within the country. A clear trend appears, namely the fact that many people are leaving Luxembourg City for another part of the country, notably the suburbs. There are 4 507 people from another municipality who settled in the capital, but 12,035 people have left for another municipality. Two different geographical models are identified for immigration and internal migration. The capital attracts many immigrants (a proportion that far exceeds the percentage of inhabitants of the capital in the total population), while for internal migration, there are more people moving from Luxembourg City to another municipality. The age structure of immigrants from abroad and people who migrate internally is very similar. It is mainly young adults and their children. [less ▲]

In Luxembourg, 28.3% of households are renters, which corresponds to 24.7% of the population. 91.9% of renter households pay a normal rent and 8.1% a reduced rent. On average, a reduced rent is € 396.7, while a normal rent reaches € 887.8 for similar surfaces (respectively 84.1 m² and 83.5 m²). In absolute terms, the rents are higher in municipalities located in the outskirts of the capital. With the distance from Luxembourg City, rents decrease. However, the housing surfaces in densely populated areas such as the City of Luxembourg, are generally smaller, so that the rent per square meter is the highest in the capital: 14.7 € per m² in the City of Luxembourg, against 12.5 € per m² on national average. Significant differences also exist in rent according to the nationality of the tenant. Britons pay on average the highest rents, but together with the Dutch, they also have larger surfaces. Montenegrins rent the smallest surface area per capita (27.5 m²). The level of rents depends on the time of moving in the dwelling. The average rent for a dwelling in which a household moved from 2001 to 2011 is € 13 per m², against € 7 per m² for a dwelling in which a household moved before 1980. [less ▲]

In Luxembourg, a household has, on average, 129.9 m² surface of dwelling. But deviations from this average are important: with increasing household size, the surface of dwelling also increases. However, the surface per capita is highest for single households, that is to say, people living alone (95.2 m²). For a household of six people or more, the surface available per person is only 30.1 m². It is in Esch-sur-Alzette where the dwelling surface per household is the lowest (96.0 m² on average), while in Niederanven the dwelling surface per household reaches 190.2 m². Dwelling surfaces also vary according to the nationality of the reference person of the household. Households whose reference person is British have the largest dwelling surface (158.7 m² per household on average), followed by the Dutch (153.6 m² per household) and Luxemburgers (140.9 m²). With 97.9 m² per household on average, the Portuguese live in smaller dwellings. There is also a link between the occupancy status and the surface of the dwelling. Owner households live in the most spacious dwellings (147.7 m² on average), while the surface available for tenant households is only 83.6 m². As the household size of owners is on average greater than that of renter households, per capita differences are smaller. The dwelling surface per capita of an owner household is 69.9 m², while for a tenant household, the dwelling surface per capita is 47.2 m². 97.0% of dwellings have a minimum standard of basic equipment, i.e. a bathroom, a toilet and central heating.

In Luxembourg, there were 130,091 residential buildings at the time of the census. Single family homes are the prevalent type of buildings. They represent 83.5% of all residential buildings. Of the single family homes, detached houses are predominant (37.9% of all residential buildings), followed by single family semi-detached houses (25.0%) and single-family homes in a row (20.6%). Apartment buildings represent only 12.5% of total residential buildings. However, the share of the population living in single family homes is only 62.6%, while 32.7% of the population is living in apartment buildings. In the 208,565 private households, there are 503,280 people, that is to say, on average, 2.41 persons per household. One third of households (33.3%) are single households. 27.4% of residents live in two-person households and 15.9% in households of three people. The real estate market is moving. 9.4% of people surveyed in Luxembourg live less than one year in their home. 34.1% live in their homes for less than 5 years. More than two thirds of households (69.0%) are homeowners, 28.3% of households live in rental and 2.7% live in homes without paying rent. The percentage varies widely by nationality, but also by municipalities. 84.5% of Luxembourgers are homeowners. The percentage of owners is generally higher in municipalities located at a certain distance from the center. In Luxembourg-City, only 47.9% are homeowners. [less ▲]

In our paper we show that when countries compete in taxes and infrastructures, coordination through a uniform tax rate or a minimum rate does not necessarily create the welfare effects observed under pure tax competition. The divergence is even worse when the competing jurisdictions differ in the quality of their institutions. If tax revenue is used to gauge the desirability of coordination, our model shows that imposing a uniform tax rate is Pareto-inferior to the non cooperative equilibrium when countries compete in taxes and infrastructures. This result is completely reversed with pure tax competition if countries are not too uneven in size. If a minimum tax rate lying between those resulting from the non-cooperative equilibrium is set, the low tax country will never be better off. Finally the paper shows that the potential social welfare gains from tax harmonization crucially depend on how heterogeneous the competing countries are. [less ▲]

Saving rates and household investment in stocks and business equity are all increasing in income and wealth. Introducing subsistence consumption to a common-across-households Epstein-Zin-Weil utility function is up to a quantitative explanation, in the context of stan- dardized parsimonious household-portfolio models with risky income. Closed forms in a sim- plified version of the model, with insurable labor-income risk and no liquidity constraints, reveal that if, (i) risky-asset returns are weakly correlated and, (ii) household resources are expected to grow over time, then poorer households can afford exiting subsistence concerns slowly by saving less and by taking less risk, while holding balanced portfolios.

We survey the problem of deciding the stability or stabilizability of uncertain linear systems whose region of uncertainty is a polytope. This natural setting has applications in many fields of applied science, from Control Theory to Systems Engineering to Biology. We focus on the algorithmic decidability of this property when one is given a particular polytope. This setting gives rise to several different algorithmic questions, depending on the nature of time (discrete/continuous), the property asked (stability/stabilizability), or the type of uncertainty (fixed/switching). Several of these questions have been answered in the literature in the last thirty years. We point out the ones that have remained open, and we answer all of them, except one which we raise as an open question. In all the cases, the results are negative in the sense that the questions are NP-hard. As a byproduct, we obtain complexity results for several other matrix problems in Systems and Control.

We study the ever more integrated and ever more unbalanced trade relationships between European countries. To better capture the complexity of economic networks, we propose two global measures that assess the trade integration and the trade imbalances of the European countries. These measures are the network (or indirect) counterparts to traditional (or direct) measures such as the trade-to-GDP (Gross Domestic Product) and trade deficit-to-GDP ratios. Our indirect tools account for the European inter-country trade structure and follow (i) a decomposition of the global trade flow into elementary flows that highlight the long-range dependencies between exporting and importing economies and (ii) the commute-time distance for trade integration,which measures the impact of a perturbation in the economy of a country on another country, possibly through intermediate partners by domino effect. Our application addresses the impact of the launch of the Euro. We find that the indirect imbalance measures better identify the countries ultimately bearing deficits and surpluses, by neutralizing the impact of trade transit countries, such as the Netherlands. Among others, we find that ultimate surpluses of Germany are quite concentrated in only three partners. We also show that for some countries, the direct and indirect measures of trade integration diverge, thereby revealing that these countries (e.g. Greece and Portugal) trade to a smaller extent with countries considered as central in the European Union network.

Procedural standards of participation have the capacity to structure and constrain the exercise of authority. Focusing on the way decisions are formed, this paper argues that the depletion of such standards in processes of reception of trans- and international decisions within the EU potentially leads to situations of unrestrained authority and can constitute a challenge to the rule of law. The first part of the paper identifies the conditions under which this may occur. It sets out the basis for a conceptual and normative analysis underpinning the argument that procedural standards of participation can be considered part of the rule of law. As such, the depletion of procedural standards emerges as one facet of a broader problem – the ability of public law to structure discretion and constrain the exercise of authority that results from internationalised procedures. These intertwined decisionmaking procedures cutting across different levels of governance challenge law’s ability to limit executive action and, hence, the rule of law premise that the exercise of public authority ought to be limited by law. In this way, and despite its EU focus, the paper contributes to analysing the challenges and possibilities of the rule of law in the current realities of diffusion of power resulting from internationalisation. This perspective requires a re-conceptualisation of the decision-making procedures that operate the substantive coordination between the sites of governance involved. The processes through which inter- and transnational rules and decisions are received in EU law are only segments of a broader regulatory cycle initiated by inter- and transnational bodies – of which the receiving authorities are either members, observers, or, otherwise active collaborating parties. Such processes can neither be fully grasped by focusing only on the segments of decision-making developed within each legal system, nor can the challenges they pose to law be apprehended from this perspective. They ought to be seen in their entirety as segments of a broader regulatory cycle. On this basis, the second part of the paper proposes two possible routes to rethink internationalised procedures [less ▲]

The digital research corpus ‘A rereading of the Werner Report of 8 October 1970 in the light of the Pierre Werner family archives’ showcases the results of the first stage of the ‘Pierre Werner and Europe’ research project (2011-2013). Based on a thorough exploration of the Werner family archives, which have been opened for the first time for research purposes, and also on other relevant archives — both Luxembourgish and international, public and private — containing multimedia material in several languages, this corpus throws light on the alchemy of the Werner Report and the mindset in which it was developed. Previously unpublished documents have helped clarify the varied, nuanced role of Pierre Werner and his personal contribution to the development and adoption of the stage-by-stage plan, on a theoretical, methodological and political level, in the context of his European achievements as a whole. The research corpus contains a comprehensive, varied selection of primary sources and related resources, as well as a detailed analytical study, which provides a new interpretation of various little-known, original sources. This corpus offers a ‘rereading’, a fresh look at the Werner Report, retracing the context and historical background in which the report was drafted and examining the work of the Werner Committee, and highlighting the impact of the Werner Plan on the path towards Economic and Monetary Union. In the interests of clarity, the study is accompanied by a list of references cited by section, as well as a list of key figures with brief biographical details, a comprehensive bibliography and a chronology.

Systemic approaches to the study of a biological cell or tissue rely increasingly on the use of context-specific metabolic network models. The reconstruction of such a model from high-throughput data can routinely involve large numbers of tests under different conditions and extensive parameter tuning, which calls for fast algorithms. We present FASTCORE, a generic algorithm for reconstructing context-specific metabolic network models from global genome-wide metabolic network models such as Recon X. FASTCORE takes as input a core set of reactions that are known to be active in the context of interest (e.g., cell or tissue), and it searches for a flux consistent subnetwork of the global network that contains all reactions from the core set and a minimal set of additional reactions. Our key observation is that a minimal consistent reconstruction can be defined via a set of sparse modes of the global network, and FASTCORE iteratively computes such a set via a series of linear programs. Experiments on liver data demonstrate speedups of several orders of magnitude, and significantly more compact reconstructions, over a chief rival method. Given its simplicity and its excellent performance, FASTCORE can form the backbone of many future metabolic network reconstruction algorithms. [less ▲]

On any simply connected Sasaki-Einstein five dimensional manifold one can construct a super Yang-Mills theory which preserves at least two supersymmetries. We study the special case of toric Sasaki-Einstein manifolds known as Y p,q manifolds. We use the localisation technique to compute the full perturbative part of the partition function. The full equivariant result is expressed in terms of certain special function which appears to be a curious generalisation of the triple sine function. As an application of our general result we study the large N behaviour for the case of single hypermultiplet in adjoint representation and we derive the N 3-behaviour in this case. [less ▲]

This paper analyzes within a simple model how a removal of bank secrecy can impact tax revenues and banks'profitability, assuming that offshore centers are able to offer sophisticated but legal, tax planning. Two alternative regimes are considered. A first, in which there is strict bank secrecy and a second, where there is international information exchange for tax purposes. In particular, we show that sharing tax information with onshore countries can be a dominant strategy for an OFC if there is enough scope for providing tax planning. Moreover, a partial reduction of tax liabilities can already prompt OFCs to voluntarily exchange relevant tax information. We also discuss the conditions under which the possible removal of bank secrecy may reduce or increase the onshore country's tax revenue. [less ▲]

This paper studies how the choice of fixed or flexible exchange rate regimes is affected by the existence of intensive and extensive margins. We study two models where firms enter during or before each period of production. We show how the the choice of those regimes depend on the level and the volatily of the intensive and extensive margins as well as on the congruence between consumers' preferences and the supply and diversity of products. We show that fixed exchange rate regimes are preferred for high enough labor supply elasticities. Fixed exchange rate regimes are unambigously better when entry occurs at the same time as production in each period. Fixed exchange rate regimes are less attractive in the presence of production lags and higher love of product diversity. [less ▲]

Fleurbaey and Maniquet have proposed the criteria of conditional equality and of egalitarian equivalence to assess the equity among individuals in an ordinal setting. Empirical applications are rare and only partially consistent with their framework. We propose a new empirical approach that relies on individual preferences, is consistent with the ordinal criteria and enables to compare them with the cardinal criteria. We estimate a utility function that incorporates individual heterogeneous preferences, obtain ordinal measures of well-being and apply conditional equality and egalitarian equivalence. We then propose two cardinal measures of well-being, that are comparable with the ordinal model, to compute Roemer’s and Van de gaer’s criteria. Finally we compare the characteristics of the worst-off displayed by each criterion. We apply this model to a sample of US micro data and obtain that about 18% of the worst-off are not common to all criteria. [less ▲]

This paper provides new empirical evidence about the relationship that may exist between real exchange rates and commodity prices in developing countries that are specialized in the export of a main primary commodity. It investigates how structural factors like the exchange rate regime, the degree of financial and trade openness, the degree of export concentration and the type of the commodity exports affect the strength of the commodity price-real exchange rate dependence.

Does commodity price volatility increase when inventories are low? We are the first ones to document this relationship. To that aim, we estimate asymmetric volatility models for a large set of commodities over 1994-2011. Since inventories are hard to measure, especially for high frequency data, we use positive return shocks as a new original proxy for inventories and find that asymmetric GARCH models reveal a significant inventory effect for many commodities. The results look robust. They hold if we allow the unconditional variance to vary over time and if we relax the parametric form. [less ▲]
