[eng] This paper examines the quantitative effects of gender gaps in entrepreneurship and labor force participation on aggregate productivity and income per capita. We simulate an occupational choice model with heterogeneous agents in entrepreneurial ability, where agents choose to be workers, self-employed or employers. The model assumes that men and women have the same talent distribution, but we impose several frictions on women's opportunities and pay in the labor market. In particular, we restrict the fraction of women participating in the labor market.

Qualsevol reflexió sobre els orígens i el desenvolupament del llenguatge no està lliure d’especulació. Malgrat les dificultats d’investigar des d’una perspectiva psicològica l’evolució humana, creiem que és necessari que les ciències del comportament contribueixin amb la seva mirada a la comprensió dels esdeveniments que ens van convertir en humans. L’objectiu d’aquest article ha estat revisar i analitzar les publicacions més significatives en matèria de filogènesi del llenguatge i de la comunicació. Després d’una introducció bàsica a conceptes claus d’antropologia evolutiva, iniciem una primera part en la qual es destrien i s’examinen meticulosament els elements més significatius que fonamenten les hipòtesis sobre els orígens del llenguatge. En un segon apartat, un cop interrelacionades i interpretades conjuntament totes les dades, es planteja una explicació sobre els orígens del llenguatge tot destacant els aspectes que ens assemblen particularment interessants com és l’emergència dels signes i el paper que ha tingut el gest com a embrió del llenguatge oral.

The final year project came to us as an opportunity to get involved in a topic which has appeared to be attractive during the learning process of majoring in economics: statistics and its application to the analysis of economic data, i.e. econometrics.Moreover, the combination of econometrics and computer science is a very hot topic nowadays, given the Information Technologies boom in the last decades and the consequent exponential increase in the amount of data collected and stored day by day. Data analysts able to deal with Big Data and to find useful results from it are verydemanded in these days and, according to our understanding, the work they do, although sometimes controversial in terms of ethics, is a clear source of value added both for private corporations and the public sector. For these reasons, the essence of this project is the study of a statistical instrument valid for the analysis of large datasets which is directly related to computer science: Partial Correlation Networks.The structure of the project has been determined by our objectives through the development of it. At first, the characteristics of the studied instrument are explained, from the basic ideas up to the features of the model behind it, with the final goal of presenting SPACE model as a tool for estimating interconnections in between elements in large data sets. Afterwards, an illustrated simulation is performed in order to show the power and efficiency of the model presented. And at last, the model is put into practice by analyzing a relatively large data set of real world data, with the objective of assessing whether the proposed statistical instrument is valid and useful when applied to a real multivariate time series. In short, our main goals are to present the model and evaluate if Partial Correlation Network Analysis is an effective, useful instrument and allows finding valuable results from Big Data.As a result, the findings all along this project suggest the Partial Correlation Estimation by Joint Sparse Regression Models approach presented by Peng et al. (2009) to work well under the assumption of sparsity of data. Moreover, partial correlation networks are shown to be a very valid tool to represent cross-sectional interconnections in between elements in large data sets.The scope of this project is however limited, as there are some sections in which deeper analysis would have been appropriate. Considering intertemporal connections in between elements, the choice of the tuning parameter lambda, or a deeper analysis of the results in the real data application are examples of aspects in which this project could be completed.To sum up, the analyzed statistical tool has been proved to be a very useful instrument to find relationships that connect the elements present in a large data set. And after all, partial correlation networks allow the owner of this set to observe and analyze the existing linkages that could have been omitted otherwise.

Fekete points are the points that maximize a Vandermonde-type determinant that appears in the polynomial Lagrange interpolation formula. They are well suited points for interpolation formulas and numerical integration. We prove the asymptotic equidistribution of Fekete points in the sphere. The way we proceed is by showing their connection to other arrays of points, the so-called Marcinkiewicz-Zygmund arrays and interpolating arrays, that have been studied recently.

Learning object repositories are a basic piece of virtual learning environments used for content management. Nevertheless, learning objects have special characteristics that make traditional solutions for content management ine ective. In particular, browsing and searching for learning objects cannot be based on the typical authoritative meta-data used for describing content, such as author, title or publicationdate, among others. We propose to build a social layer on top of a learning object repository, providing nal users with additional services fordescribing, rating and curating learning objects from a teaching perspective. All these interactions among users, services and resources can be captured and further analyzed, so both browsing and searching can be personalized according to user pro le and the educational context, helping users to nd the most valuable resources for their learning process. In this paper we propose to use reputation schemes and collaborative filtering techniques for improving the user interface of a DSpace based learning object repository.

Annualising work hours (AH) is a means of achievement flexibility in the use of human resources to face the seasonal nature of demand. In Corominas et al. (1) two MILP models are used to solve the problem of planning staff working hours with annual horizon. The costs due to overtime and to the employment of temporary workers are minimised, and the distribution of working time over the course of the year for each worker and the distribution of working time provided by temporary workers are regularised.In the aforementioned paper, the following is assumed: (i) the holiday weeks are fixed a priori and (ii) the workers are from different categories who are able to perform specific type of task have se same efficiency; moreover, the values of the binary variables (and others) in the second model are fixed to those in the first model (thus, in the second model these will intervene as constants and not as variables, resulting in an LP model).In the present paper, these assumptions are relaxed and a more general problem is solved. The computational experiment leads to the conclusion that MILP is a technique suited to dealing with the problem.

Els programes Leader de la Unió Europea tenen com a objectiu el desenvolupament de territoris rurals.La comarca catalana de l’Alt Urgell es va beneficiar anteriorment de l’aplicació del programa Leader 2en set municipis del sud de la comarca. L’actual convocatòria anomenada Leader Plus té en canvi unàmbit d’aplicació que afecta a la totalitat del territori de l’Alt Urgell.A més de l’àmbit territorial, també els objectius estratègics són diferents. Leader 2 pretenia corregir lesconseqüències negatives de la crisi industrial de Taurus. Per aquest motiu, el seu objectiu fonamentalconsistia en aturar la pèrdua de població del territori i va donar molta importància a la creaciód’ocupació i les inversions en la indústria. En canvi, el programa Leader Plus té com a objectiu bàsicestabilitzar la població i millorar el benestar econòmic en els nuclis rurals. Per aquesta raó prioritza lesinversions en sectors con el turisme o altres serveis que ajudin a millorar la qualitat de vida de les zonesrurals.Les conclusions d’aquest treball han servit com a referència per a la redacció de les bases que hauran deservir per a la determinació de quins tipus d’inversions es poden acollir a la iniciativa Leader Plus al’Alt Urgell i quines subvencions es poden concedir.

This paper presents a regional analysis of the effects of educational policies implemented in Spain between 1992 and 2003, focusing specifically on school failure rates. We consider the impact of expenditure per pupil, class size, and pupil-teacher ratio on dropout rates at the end of compulsory education and on the proportion of early school-leavers in the 18-24 year age group. Our results indicate that higher levels of educational expenditure per pupil and lower class sizes and pupil-teacher ratios reduce rates of dropout and early school-leaving (although class-size is not always significant). However, the magnitude of the effects of these variables is small at the average level.
