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. Si les deux parents sont nés au Grand-Duché, la langue principale des enfants est dans 98.3% des cas le luxembourgeois ; si les deux parents sont nés à l’étranger, ce taux est seulement de 50.4%. Pour les immigrés, le taux de ceux qui indiquent le luxembourgeois comme langue principale augmente avec la durée de séjour: Pour ceux arrivés avant 1962, la proportion est de 49.8% ; pour ceux venus entre 2007 et 2011, elle tombe à 1.5%. 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%.

In diesem Beitrag wird untersucht, wie praxistheoretische mit raumtheoretischen Überlegungen verknüpft und in eine Heuristik der kulturwissenschaftlichen Raumanalyse überführt werden können. Diese Fragestellung resultiert aus der Einsicht, dass Raum als ein emergenter Aspekt des Sozialen zu betrachten ist und dass er in den Border Studies noch weitgehend unterbestimmt ist. 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. Von besonderem heuristischen Nutzen erweisen sich die vielfältigen Verbindungen zwischen diesen Analysekategorien. [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 ▲]

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.

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 ▲]

70.5% of the population uses Luxembourgish at work, school and/or at home, 55.7% French and 30.6% German. On average 2.2 languages ​​are used. Adolescents and young adults exceed this average, while children and the elderly are below. About half of the Germans, Dutch and Montenegrins living in Luxembourg use Luxembourgish and occupy the first three places among the foreign nationalities speaking Luxembourgish. The use of Luxembourgish by immigrants increases with the duration of their stay. In rural regions, especially in the north of the country, where the rate of foreigners is relatively low, the percentage of the resident population using Luxembourgish generally exceeds 80% (Consthum 94.8%). In Luxembourg City the rate is only 48.8%. [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, 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 ▲]

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 continue our study on the partition function for 5D supersymmetric Yang-Mills theory on toric Sasaki-Einstein Yp,q manifolds. Previously, using the localisation technique we have computed the perturbative part of the partition function. In this work we show how the perturbative part factorises into four pieces, each corresponding to the perturbative answer of the same theory on R4×S1. This allows us to identify the equivariant parameters and to conjecture the full partition functions (including the instanton contributions) for Yp,q spaces. The conjectured partition function receives contributions only from singular contact instantons supported along the closed Reeb orbits. At the moment we are not able to prove this fact from the first principles. [less ▲]

This paper investigates a consumption-real exchange rate anomaly from the open macroeconomics literature known as the Backus-Smith puzzle . We both analytically and quantitatively examine how an expansion of trade along extensive margins can contribute to the puzzle s resolution. Our argument is based on 1) a wealth effect due to changes in the number of product varieties, 2) statistical inefficiency in measuring the number of product varieties, and 3) market incompleteness. Contrary to complete asset markets which, in general, feature overly strong risk sharing properties, changes in the number of product varieties under incomplete markets may produce a wealth e¤ect under high trade elasticity. Since statistical agencies systematically fail to capture the welfare impact arising from that changes, data-consistent terms of trade and real exchange rates tend to appreciate due to this positive wealth effect. This provides a realistic correlation between data-consistent real exchange rates and consumption. [less ▲]

This paper explores the role played by product variety and quality in a real business cycle model. Firms are heterogeneous in terms of their speci c quality as well as pro- ductivity levels. Firms which have costly technology enter in a period of high aggregated demand and produce high quality goods. Thus, the average quality level and number of available varieties are procyclical, as in the data. The model can replicate the observed in flationary bias in the conventional Consumer Price Index due to a rise in the number of new product varieties and quality. [less ▲]

We study how excessive debt-GDP ratios affect political sustainability of prudent fiscal policy in country members of a monetary union. We develop a model with free choice of distinct rent-seeking groups to cooperate (or not) in providing public goods, in seeking rents, and in austere debt issuing through international markets. Noncooperation of rent-seeking groups on fiscal prudence triggers collective fiscal impatience: fiscal debt is issued excessively because each group expropriates extra rents before other groups do so, too. Such collective fiscal impatience leads to a vicious circle of high international interest rates and external-debt default. Our calibration suggests that debt-GDP ratios below 137% foster cooperation among rent-seeking groups, which avoids collective fiscal impatience and default. Our analysis helps in understanding the politicoeconomic sustainability of sovereign rescue packages, emphasizing the need for fiscal targets and for possible debt haircuts. [less ▲]

The class of threshold functions is known to be characterizable by functional equations or, equivalently, by pairs of relations, which are called relational constraints. It was shown by Hellerstein that this class cannot be characterized by a finite number of such objects. In this paper, we investigate classes of threshold functions which arise as intersections of the class of all threshold functions with clones of Boolean functions, and provide a complete classification of such intersections in respect to whether they have finite characterizations. Moreover, we provide a characterizing set of relational constraints for each class of threshold functions arising in this way. [less ▲]

Stein operators are differential operators which arise within the so-called Stein's method for stochastic approximation. We propose a new mechanism for constructing such operators for arbitrary (continuous or discrete) parametric distributions with continuous dependence on the parameter. We provide explicit general expressions for location, scale and skewness families. We also provide a general expression for discrete distributions. For specific choices of target distributions (including the Gaussian, Gamma and Poisson) we compare the operators hereby obtained with those provided by the classical approaches from the literature on Stein's method. We use properties of our operators to provide upper and lower variance bounds (only lower bounds in the discrete case) on functionals h(X) of random variables X following parametric distributions. These bounds are expressed in terms of the first two moments of the derivatives (or differences) of h. We provide general variance bounds for location, scale and skewness families and apply our bounds to specific examples (namely the Gaussian, exponential, Gamma and Poisson distributions). The results obtained via our techniques are systematically competitive with, and sometimes improve on, the best bounds available in the literature. [less ▲]

In this article we study the implication of thresholds in preferences. To model this we extend the basic model of John and Pecchenino (1994) by allowing the current level of environmental quality to have a discrete impact on how an agent trades o future consumption and environmental quality. In other words, we endogenize the semi-elasticity of utility based on a step function. We motivate the existence of the threshold based on research from political science, from arguments based on regulation and standards, cultural economics as well as ecological economics. Our results are that the location of the threshold determines both the potential steady states as well as the dynamics. For low (high) thresholds, environmental quality converges to a low (high) steady state. For intermediate levels it converges to a stable p-cycle, with environmental quality being asymptotically bounded below and above by the low and high steady state. We discuss implications for intergenerational equity and policy making. As policy implications we study shifts in the threshold. Our results are that, in case it is costless to shift the threshold, it is always worthwhile to do so. If it is costly to change the threshold, then it is worthwhile to change the threshold if the threshold originally was suffi ciently low. Lump-sum taxes may lead to a development trap and should be avoided if there are uncertainties about the threshold or the effectiveness of the policy. [less ▲]

Does population aging and the associated increase in the old-age dependency ratio affect economic growth ? The answer is given in a novel analytical framework that allows for population aging to affect endogenous capital- and labor-saving technical change. The short-run analysis reveals that population aging induces more labor- and less capital-saving technical change as it increases the relative scarcity of labor with respect to capital. Due to external contemporaneous knowledge spill-overs across innovating firms induced technical change has a first-order effect on current aggregate income. In the long-run capitalsaving technical progress vanishes, and the economy’s growth rate reflects only labor-saving technical change. However, the mere possibility of capital-saving technical change is shown to imply that the economy’s steady-state growth rate becomes independent of its age structure: neither a higher life-expectancy nor a decline in fertility affects economic growth in the long run.

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 ▲]

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 ▲]
