[more ▼]Sequence discovery tools play a central role in several fields of computational biology. In the framework of Transcription Factor binding studies, motif finding algorithms of increasingly high performance are required to process the big datasets produced by new high-throughput sequencing technologies. Most existing algorithms are computationally demanding and often cannot support the large size of new experimental data. We present a new motif discovery algorithm that is built on a recent machine learning technique, referred to as Method of Moments. Based on spectral decompositions, this method is robust under model misspecification and is not prone to locally optimal solutions. We obtain an algorithm that is extremely fast and designed for the analysis of big sequencing data. In a few minutes, we can process datasets of hundreds of thousand sequences and extract motif profiles that match those computed by various state-of-the-art algorithms.

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.

[more ▼]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.

[more ▼]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.

[more ▼]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.

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.

In the semimartingale case, that is, where the Hurst parameter H of the fractional part satisfies H∈(3/4,1), the central limit theorem holds. In the nonsemimartingale case, that is, where H∈(1/2,3/4], the convergence toward the normal distribution with a nonzero mean still holds if H=3/4, whereas for the other values, that is, H∈(1/2,3/4), the central convergence does not take place. We also provide Berry--Esseen estimates for the estimator.

A ... [more ▼]his research theoretically and empirically advances the hypothesis that in early stages of development, land and climatic variability had a persistent beneficial effect on the advent of early statehood. A high degree of land and climatic diversity, and its association with potential gains from trade, accentuated the incentives to develop social, political and physical infrastructure that could facilitate interregional interaction. Hence, the emergence of states was expedited in more diverse geographical environments. To explore the hypotheses the analysis exploits exogenous sources of variation in a) the measure of land variability across countries, and b) climatic variability within countries over the period 500-1500 CE. The research establishes that i) the advent of statehood was expedited in regions characterized by a higher degree of variability in land and climatic conditions, ii) the effect of (land and climatic) variability on statehood operates partly through the advancement of technologies associated with trade, thus suggesting that it is the pivotal role of states in facilitating trade that ultimately contributed to their emergence and consolidation, and, iii) the effect of land variability on statehood dissipates over time [less ▲]Detailed reference viewed: 30 (4 UL) Natural Land Productivity, Cooperation and Comparative DevelopmentLitina, Anastasia E-print/Working paper (2014)ssion Paper Series 14-16, Center for Research in Economic Analysis, University of Luxembourg.

Abstract: This research advances the hypothesis that natural land productivity in the past, and its effect on the desirable level of cooperation in the agricultural sector, had a persistent effect on the evolution of social capital, the process of industrialization and comparative economic development across the globe.

[more ▼]his research exploits the event of immigration to establish that institutions have a persistent effect on culture. It is argued that immigrants coming from corrupt countries, tend to overtrust the institutions at the host country. This inflated trust of immigrants is documented as the Great Expectations effect. This result is interesting and intriguing for several reasons. First, it highlights the persistent effect of institutions (at the origin coun- try) on the cultural attitudes of immigrants. Interestingly, this effect is rather persistent and can be detected even to the second generation immigrants. Second, the analysis explores whether mean attitudes at the origin country have an effect on immigrants. attitude. The findings suggest that mean attitudes do not confer a statistically significant effect, whereas a horserace between origin institutions and origin culture suggests that it is the effect of institutions that prevails. Last, the analysis establishes that the inflated trust of immigrants affects their political attitudes. Immigrants coming from corrupt countries tend to be less interested in politics, to overtrust the host governments and to be less active in the political arena. In a globalized world where international immigration is rather extensive, pinning down the cultural differences across immigrants and thus the differences in their political attitudes is of an essence.

[more ▼]Il Consiglio dell’Unione europea ha recentemente adottato delle Conclusioni sulla coerenza fra aspetti esterni ed interni della protezione e promozione dei diritti umani nell’Unione europea. Tale strumento attira l’attenzione su un problema cruciale: l’Unione promuove da anni il rispetto di taluni diritti umani che i suoi stessi membri non sembrano proteggere, o che interpretano in modo difforme. Tale contraddizione è difficile da giustificare sul piano teorico ed è pericolosa su quello pratico, dato che pregiudica la credibilità dell’Unione sulla scena internazionale. Per risolvere questo problema, sarebbe opportuno che gli Stati membri inizino ad applicare in Europa le stesse regole che intendono diffondere nel mondo.

On average, the mutual funds’ costs of immediacy exceed their returns from providing liquidity. The funds with outflows, flows that correlate with industry flows, high market beta funds, and funds highly exposed to the momentum strategy suffer the most in costs of immediacy. The mutual funds’ average underperformance can be explained with their costs of immediacy. Finally, the funds’ historical costs of immediacy predict their alphas.

[more ▼]This contribution is an excerpt from the report on the economic and social situation of the Greater Region 2013/2014 for the Economic and Social Committee of the Greater Region (IBA/OIE, 2014, pp. 3-10). The maps show the population density in the Greater Region as of 1 January 2013, the working-age population as of 1 January 2012 and the population development from 2000 to 2013 (Lorraine: zones d'emploi 1999-2011), calculated by the Interregional Labour Market Observatory IBA. The population density of the Greater Region in 2013 was almost 175 inhabitants per square kilometre, although the distribution varies widely from regionally: from more than 2,000 inhabitants per square kilometre in Mainz and Ludwigshafen to the sparsely populated areas of Verdun and Commercy with less than 30 inhabitants per square kilometre. This is where important economic priorities lie and influences from the large conurbations of neighboring federal states have an impact. Densely populated areas are also located in the northern part of Wallonia, particularly in the economic centres of Charleroi and Liège. In addition, the population of the Greater Region concentrates primarily on a transnational core area, which encompasses all sub-regions and important economic priorities.

[more ▼]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.

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

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.

[more ▼]We study first-mover advantages in the hedge fund industry by clustering hedge funds based on the type of assets and instruments they trade in, sector and investment focus, and fund details. We find that early entry in a cluster is associated with higher excess returns, longer survival, higher incentive fees and lower management fees compared to funds that arrive later. Moreover, the latest entrants have a high loading on the returns of the innovators, but with lower incentive fees, and higher management fees. Cross-sectional regressions show that the out-performance of innovating funds are declining with age. The results are robust to different parameters of clustering and backfill-bias, and are not driven by the possible existence of flagship and follow-on funds. Our results show that the reported characteristics of hedge funds can be used to infer strategy-related information and suggest that specific first-mover advantages exist in the hedge fund industry.

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

We highlight the similarity between the SFEM and the virtual element method (VEM). Based on the VEM, we propose a new stabilization approach to the SFEM when applied to arbitrary polygons and polyhedrons. The accuracy and the convergence properties of the SFEM are studied with a few benchmark problems in 2D and 3D linear elasticity. Later, the SFEMis combined with the scaled boundary finite element method to problems involving singularity within the framework of the linear elastic fracture mechanics in 2D.

[more ▼]The ePublication ‘The “Franco-German duo” and Europe as seen in cartoons (1945–2013)’ uses French and German press illustrations to explore the joint action of successive French Presidents and German Chancellors as the driving force of European integration. The rapprochement that began in the early years after the Second World War between France and Germany, two countries that had been long-standing enemies, followed a unique path. The image of a ‘Franco-German duo’ and the pair’s actions have proved an unending source of inspiration for French and German Press cartoonists. It shows how they have experienced, perceived and illustrated this Franco-German partnership, which has continued to evolve during the turbulent history of European integration. This comparative analysis reflects the convergences and divergences within this unique pairing and demonstrates the ever-changing balance of power within the partnership. The cartoons also reveal the fact that there is often a discrepancy between official photos and the reality of the Franco-German relationship. Although the Franco-German duo and its ability to act for the organisation of Europe have at times proved fragile, with periods of tension but also of continuity, the relationship between the various West German Chancellors and French Presidents has made an often decisive contribution to the pursuit and revival of European integration. Over 400 cartoons published in the French and German press reflect the key moments in Franco-German relations and emphasise how this ‘marriage of convenience’ between two leaders has influenced the European integration process, illustrating both the successes and failures of the duo. The selected cartoons provide an often cheeky, sarcastic interpretation of the Franco-German duo, that special relationship, which, despite its periods of tension and crisis, has always bounced back and has often served as a driving force for European unification. The cartoons reflect the two leaders’ attitudes to the challenges of the European integration process, painting an often humorous but at times openly critical picture of this bilateral relationship.

[more ▼]Change-point (CP) and Markov-switching (MS) Auto-regressive models have been intensively discussed over the last two decades due to their flexibility and their relatively simple estimations. Although CP- and MS-ARMA models constitute a natural extension, they have been barely studied. The main reason comes from that classical inference fails when estimating these models. In particular the CP- and MS-ARMA models exhibit path dependence problem that renders the likelihood out of reach. We propose an estimation method that circumvents the issue. Our MCMC algorithm resting on the sticky in.finite hidden Markov-switching model (sticky IHMM) self-determines the number of regimes as well as the specification : CP or MS. Furthermore, the CP and MS frameworks usually assume that all the model parameters vary from one regime to another. We relax this restrictive assumption. As illustrated by simulations realized on moderate samples (300 observations), the sticky IHMM-ARMA algorithm detects which parameters of the model change over regimes. Applications to the U.S. GDP growth and the DJIA realized volatility highlight this flexibility by estimating different structural breaks for the mean and the variance parameters.

[more ▼]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.

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.

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.

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.

countries within and outside a tax union, in which countries are supposed to compete
in taxes and infrastructure. Our results demonstrate that, a subgroup of countries
agreeing on a common tax rate, can harm both member and nonmember
states. This is in contrast to the classical findings that partial tax harmonization
is Pareto improving. When a minimum tax rate is imposed within a tax union, we
demonstrate that it does not necessarily improve the welfare of the member countries.
Moreover, both the high tax and low tax countries can be worse off. This
conclusion is at odds with the classical result that a high tax country benefits from
