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. La part des personnes ayant un diplôme de type « master » ou un doctorat (33.9%) est plus de deux fois plus élevé que dans le pays en général (14.8%). En revanche, les niveaux d’éducation faibles ou moyens sont moins fréquents dans la capitale que dans le reste du pays. [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 ▲]

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 ▲]

Damit ist ihre ab-solute Zahl die höchste, die bei einer Volkszählung seit 1875 gemessen wurden. Verglichen mit der Gesamtbevölkerung sind die Belgier im Durch-schnitt geringfügig älter (39.3 Jahre vs. 38.7 Jahre). Mit 73.6 % wurde die Mehrheit der Belgier in Belgien geboren, weitere 17.2 % wurden in Luxemburg ge-boren. In absoluten Zahlen wohnen die meisten Belgier in Luxemburg-Stadt (3 892), ihr Anteil an Wohnbevölkerung ist jedoch in Winseler mit 17.9 % deutlich höher als in der Hauptstadt (4.1 %).

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. Overall, the education level of french people living in Luxembourg is higher than that of the total population. [less ▲]

Un peu plus d’un quart (27%) de la population âgée d’au moins 15 ans ne poursuivant plus d’études possèdent un diplôme de l’enseignement supérieur. Ce pourcentage est un peu plus élevé chez les hommes que chez les femmes (29.7% contre 24.5%). En revanche, un cinquième de la population (19.9%) n’a pas dépassé le niveau d’enseignement primaire. La part des personnes ayant atteint le niveau du secondaire inférieur est de 14.6% et 35.5% de la population ont atteint un niveau d’éducation du secondaire supérieur. Depuis 2001, une augmentation du niveau d’éducation est observée. La part des diplômés de l’enseignement supérieur passe de 19.6% en 2001 à 27.0% en 2011. Les générations les plus âgées ont un niveau d’éducation moins élevé que les générations plus jeunes : 53.5% des 85 ans et plus ont, au maximum, atteint le niveau d’enseignement primaire, contre seulement 9.4% des 20 à 39 ans. Les personnes de nationalité étrangère sont surreprésentées pour deux niveaux d’éducation : le primaire et le supérieur. 24.4% des étrangers n’ont atteint que le niveau d’éducation primaire, contre 16.8% des Luxembourgeois. En revanche 31.8% des étrangers ont atteint un niveau d’éducation supérieur, contre seulement 23.7% des Luxembourgeois. Le type de diplôme obtenu à une grande influence sur la profession exercée. 88.6% des personnes qui travaillent dans les professions intellectuelles et scientifiques ont un diplôme de l’enseignement supérieur, alors qu’ils ne représentent que 1.8% des personnes exerçant une profession élémentaire.

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 February 1st 2011 (Census Day), 18,059 Italians lived in Luxembourg and made up 3.5% of the total population. Their number has decreased since 1970. In that year 23,490 Italians (6.9% of the total population) are still counted. In 1960, Italians accounted for 37.8% of all foreigners living in Luxembourg. 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).

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 ▲]

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%).

61.2% de la population du Grand-Duché ont un « background » migratoire, soit directement ou indirectement à travers les parents. À contrario, 38.8% des résidents n’ont pas d’arrière-plan migratoire (Luxembourgeois nés au Grand-Duché de parents tous les deux également nés au Luxembourg). Le « background » migratoire d’une personne peut être appréhendé à travers sa nationalité, son lieu de naissance, mais également à travers le lieu de naissance des parents. Les personnes de nationalité étrangère nées à l’étranger de deux parents également nés à l’étranger représentent 32.0% de la population. Près d’un dixième de la population (8.5%) est né au Luxembourg de parents nés tous les deux à l’étranger et est de nationalité étrangère. Parmi ces personnes, nous retrouvons pour près de la moitié des Portugais. 4.6% des résidents sont Luxembourgeois nés au Grand-Duché de deux parents nés à l’étranger. 4.3% des personnes résidentes sont luxembourgeoises nées à l’étranger et dont les deux parents sont également nés à l’étranger.

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 ▲]

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 ▲]

We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor productivity are more profitable. We incorporate this channel in a new dynamic general equilibrium model with endogenous economic growth and heterogeneous overlapping generations. We calibrate the model for the US economy and obtain the following results. First, the effect of a decline in population growth on labor productivity growth is positive and quantitatively significant. In our benchmark, it is predicted to increase from an average annual growth rate of 1.74% over 1990-2000 to 2.41% in 2100. Second, institutional characteristics of the pension system matter both for the growth performance and for individual welfare. Third, the assessment of pension reform proposals may depend on whether economic growth is endogenous or exogenous. [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.

Uzawa’s steady-state growth theorem (Uzawa (1961)) is generalized to a neoclassical economy that uses current output, e. g., to create technical progress or to manufacture intermediates. The difference between aggregate final-good production and these resources is referred to as net output. The new generalized steady-state growth theorem holds since net output exhibits constant returns to scale in capital and labor. This insight provides an understanding for why technical change is labor-augmenting in steady state even if capital-augmenting technical change is feasible. By example, this point is made for three recent growth models that allow for endogenous capital- and labor-augmenting technical change, namely, Irmen (2013), Acemoglu (2003), and Acemoglu (2009), Chapter 15. The reduced form of these models is shown to be consistent with the generalized steady-state growth theorem. [less ▲]

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.

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 ▲]

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.

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 ▲]

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 ▲]

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 ▲]

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.

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 ▲]

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 ▲]

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.

We describe a bicategory (Red Orb) of reduced orbifolds in the framework of differential geometry (i.e. without any explicit reference to notions of Lie groupoids or differentiable stacks, but only using orbifold atlases, local lifts and changes of charts). In order to construct such a bicategory, we first define a 2-category (Red Atl) whose objects are reduced orbifold atlases (on paracompact, second countable, Hausdorff topological spaces). The definition of morphisms is obtained as a slight modification of a definition by A. Pohl, while the definition of 2-morphisms and compositions of them is new in this setup. Using the bicalculus of fractions described by D. Pronk, we are able to construct from such a 2-category the bicategory (Red Orb). We prove that it is equivalent to the bicategory of reduced orbifolds described in terms of proper, effective, étale Lie groupoids by D. Pronk and I. Moerdijk and to the 2-category of reduced orbifolds described by several authors in the past in terms of a suitable class of differentiable Deligne-Mumford stacks. [less ▲]

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 ▲]

Resource income in a multi-regional setting allows for differentiated impacts of windfalls on the industrial development of each region. A resource exporting region suffers from Dutch disease through a spending effect and a real exchange rate ap- preciation. Whereas, a neighboring region will suffer from the real exchange rate appreciation but the increased demand from the region with the resource income of tradable goods will increase the traded good sector in the neighboring region. For a 2-region 2-sector model the equilibrium conditions on the labour allocation between the sectors are derived taking into account resource potential windfalls. The model is tested on and supported by a panel dataset of Canadian provinces. [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 revisits Schumpeterian destruction in a DSGE model based on monopolistic competition. Firms enter the market through a free entry condition and exit endogenously depending on their specific productivity level. The mechanism of endogenous destruction among heterogeneous firms is based on the probabilistic argument discussed in Melitz (2003). The models in the paper are successful in reproducing observed business cycle patterns for creation and destruction and other major economic variables. The models also feature typical characteristics of Schumpeterian economies as found in literature. [less ▲]

This paper studies how the choice of xed or exible exchange rate regimes is a¤ected by the existence of intensive and extensive margins. We study two models where rms enter during or before each period of production. We show how 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 xed 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 ▲]

Software verification of evolving systems is challenging mainstream methodologies and tools. Formal verification techniques often conflict with the time constraints imposed by change management practices for evolving systems. Since changes in these systems are often local to restricted parts, an incremental verification approach could be beneficial. This paper introduces SiDECAR, a general framework for the definition of verification procedures, which are made incremental by the framework itself. Verification procedures are driven by the syntactic structure (defined by a grammar) of the system and encoded as semantic attributes associated with the grammar. Incrementality is achieved by coupling the evaluation of semantic attributes with an incremental parsing technique. We show the application of SiDECAR to the definition of two verification procedures: probabilistic verification of reliability requirements and verification of safety properties. [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 ▲]

Germany has among the most highly stratified and segregated educational systems in Europe. Its differentiated special school system, in particular, exemplifies institutional inertia. Yet Article 24 of the United Nations Convention on the Rights of Disabled People (UN-CRPD), ratified in Germany in 2008, mandates implementation of inclusive education. To achieve the UN-CRPD’s goals, Germany’s sixteen Bundesländer must radically transform their education systems, whose structures remain antithetical to inclusive education. Examining education policy reform processes in two contrasting cases, we investigate four types of mechanisms of institutional reproduction responsible for path-dependent developments: power-based, legitimacy-based, utilitarian, and functional. We compare Schleswig-Holstein, where inclusive education has diffused broadly, with Bavaria, where implementation has stalled due to backlash and school segregation remains pervasive. Delving below the national level and emphasizing the importance of timing, we show contrasting effects of an exogenous shock on the direction of endogenous reforms. [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 ▲]
