Economic growth is projected to be strengthening from mid-2011 onwards, but will be insufficient to restore the sustainability of public finances. The Belgian strategy to prefund ageing costs by generating fiscal surpluses to bring down public debt was derailed by the global crisis. Restoring the strategy is a priority, especially as spreads on Belgian debt have increased. This will require cuts in public spending, improving efficiency of policies, containing the growth of ageing-related costs and making the tax system more conducive to growth. While past experiences, such as in the 1990s, have shown that successful large consolidations are feasible, the task seems even more difficult this time as potential growth will be muted and interest rates are likely to increase. In this context, a credible fiscal consolidation plan requires the participation of all governments. Its effectiveness can be strengthened by improving the fiscal framework, in particular by introducing multi-year budgets, annual expenditure rules consistent with long-term targets and an enhanced role of an independent fiscal policy watchdog [less ▲]

The specificities of the workforce with a migrant background are often neglected in studies of retirement. Similarly, many studies of migration’s impact on pensions often focus on aggregate outcomes – system sustainability or distributive characteristics. The present paper provides a fresh look at the nexus between these two literatures. It discusses the impact of the European social security coordination mechanisms on individual decision‐making and on the functioning of social security systems – with a focus on retirement. The paper argues that such effects are non‐negligible and are likely to have major policy consequences. [less ▲]

The paper addresses the problem of low-rank trace norm minimization. We propose an algorithm that alternates between fixed-rank optimization and rank-one updates. The fixed-rank optimization is characterized by an efficient factorization that makes the trace norm differentiable in the search space and the computation of duality gap numerically tractable. The search space is nonlinear but is equipped with a particular Riemannian structure that leads to efficient computations. We present a second-order trust-region algorithm with a guaranteed quadratic rate of convergence. Overall, the proposed optimization scheme converges super-linearly to the global solution while still maintaining complexity that is linear in the number of rows of the matrix. To compute a set of solutions efficiently for a grid of regularization parameters we propose a predictor-corrector approach on the quotient manifold that outperforms the naive warm-restart approach. The performance of the proposed algorithm is illustrated on problems of low-rank matrix completion and multivariate linear regression. [less ▲]

We propose a new Riemannian geometry for fixed-rank matrices that is specifically tailored to the low-rank matrix completion problem. Exploiting the degree of freedom of a quotient space, we tune the metric on our search space to the particular least square cost function. At one level, it illustrates in a novel way how to exploit the versatile framework of optimization on quotient manifold. At another level, our algorithm can be considered as an improved version of LMaFit, the state-of-the-art Gauss-Seidel algorithm. We develop necessary tools needed to perform both first-order and second-order optimization. In particular, we propose gradient descent schemes (steepest descent and conjugate gradient) and trust-region algorithms. We also show that, thanks to the simplicity of the cost function, it is numerically cheap to perform an exact linesearch given a search direction, which makes our algorithms competitive with the state-of-the-art on standard low-rank matrix completion instances.

Motivated by the problem of learning a linear regression model whose parameter is a large fixed-rank non-symmetric matrix, we consider the optimization of a smooth cost function defined on the set of fixed-rank matrices. We adopt the geometric optimization framework of optimization on Riemannian matrix manifolds. We study the underlying geometries of several well-known fixed-rank matrix factorizations and then exploit the Riemannian geometry of the search space in the design of a class of gradient descent and trust-region algorithms. The proposed algorithms generalize our previous results on fixed-rank symmetric positive semidefinite matrices, apply to a broad range of applications, scale to high-dimensional problems and confer a geometric basis to recent contributions on the learning of fixed-rank non-symmetric matrices. We make connections with existing algorithms in the context of low-rank matrix completion and discuss relative usefulness of the proposed framework. Numerical experiments suggest that the proposed algorithms compete with the state-of-the-art and that manifold optimization offers an effective and versatile framework for the design of machine learning algorithms that learn a fixed-rank matrix.

Assuming that observers located inside the Universe measure a time flow which is different from the time appearing in the Friedmann-Lemaıtre equation, and determining this time flow such that the Universe always appears flat to these observers, we derive a simple cosmological model which allows to explain the velocity dispersions of galaxies in galaxy clusters without introducing dark matter. It also solves the horizon problem without recourse to inflation. Moreover, it explains the present acceleration of the expansion without any resort to dark energy and provides a good fit to the observations of distant supernovæ. Depending on the present value of the matter-energy density, we calculate an age of the Universe between 15.4 and 16.5 billion years, ignificantly larger than the 13.7 billion years of the standard CDM model. Our model has a slower expansion rate in the early epochs, thus leaving more time for the formation of structures such as stars and galaxies. [less ▲]

In liberalized network industries, entrants can either compete for service using the existing infrastructure (access) or deploy their own infrastructure capacity (bypass). In this paper, we demonstrate that, under the threat of bypass, the access price set by an unregulated and vertically integrated incumbent is compatible with productive efficiency. This means that the entrant bypasses the existing infrastructure only if it can produce the network input more efficiently. We show that the incumbent lowers the access price compared to the ex-post efficient level to strategically deter inefficient bypass by the entrant. Accordingly, from a productive efficiency point of view, there is no need to regulate access prices when the entrant has the option to bypass. Despite that, we show that restricting the possibilities of access might be profitable for consumers and welfare because competition is fiercer under bypass. [less ▲]

Under income-differentiated mortality, poverty measures reflect not only the "true" poverty, but, also, the interferences or noise caused by the survival process at work. Such interferences lead to the Mortality Paradox: the worse the survival conditions of the poor are, the lower the measured poverty is. We examine several solutions to avoid that paradox. We identify conditions under which the extension, by means of a fictitious income, of lifetime income profiles of the prematurely dead neutralizes the noise due to differential mortality. Then, to account not only for the "missing" poor, but, also, for the "hidden" poverty (premature death), we use, as a fictitious income, the welfare-neutral income, making indifferent between life continuation and death. The robustness of poverty measures to the extension technique is illustrated with regional Belgian data. [less ▲]

Transport costs play a key role in agricultural markets in developing countries and are one of the causes of poverty amongst farmers that are geographically isolated. Another characteristic of agricultural markets is that they often involve interlinked transactions. However, the existing theoretical literature on interlinked transactions does not take into account the existence of transport costs. This paper develops a model of input-output interlinked contracts between geographically dispersed farmers and a trader, whether this trader is for-profit or non-profit. We derive implications of imposing either uniform or mill pricing policies, as opposed to spatial price discrimination. Impact on profit, farmers' income, level of production, social welfare and regional disparities are investigated. [less ▲]

The Gl 581 planetary system has generated wide interest, because its 4 planets include both the lowest mass planet known around a main sequence star other than the Sun and the first super-Earth planet in the habitable zone of its star. A recent paper announced the possible discovery of two additional super-Earth planets in that system, one of which would be in the middle of the habitable zone of Gl 581. The statistical significance of those two discoveries has, however, been questioned. We have obtained 121 new radial velocity measurements of Gl 581 with the HARPS spectrograph on the ESO 3.6 m telescope, and analyse those together with our previous 119 measurements of that star to examine these potential additional planets. We find that neither is likely to exist with their proposed parameters. We also obtained photometric observations with the 2.5 m Isaac Newton Telescope during a potential transit of the inner planet, Gl 581e, which had a 5% geometric transit probability. Those observations exclude transits for planet densities under 4 times the Earth density within -0.2 sigma to +2.7 sigma of the predicted transit center. [less ▲]

Cette note a pour objectif d’illustrer, dans le cas de la Belgique et de ses régions, un problème particulier posé par la mesure de la pauvreté. Etant donné que la mortalité varie selon le niveau de revenu – les personnes aux revenus plus élevés vivant plus longtemps, en moyenne, que les personnes aux revenus plus faibles – les taux de pauvreté calculés pour les classes âgées dépendent non seulement de ce que l’on pourrait appeler la vraie pauvreté, mais aussi de la sélection induite par la mortalité différentielle selon le revenu. En calculant les taux de pauvreté que l’on observerait si des personnes avec différents niveaux de revenus avaient toutes la même espérance de vie, on peut ainsi estimer la vraie pauvreté, en neutralisant les interférences dues à la mortalité différentielle. Cet ajustement des mesures de pauvreté est particulièrement intéressant pour la Belgique, où les écarts de longévité entre Flamands et Francophones et entre riches et moins riches sont importants.

Le discours d'information médiatique se caractérise certes par sa forme fragmentaire quant aux énoncés (par définition ouverts sur l'avenir et s’additionnant sans suite cohérente), mais encore par une forme d'énonciation « floue » parce que collective, voire institutionnelle. Nous examinons ici la manière dont, dans le discours journalistique, la dimension collective de la langue est rapportée sur la parole et sur l’acte d’énonciation. Nous considérons que l’énonciation journalistique est, à plusieurs titres, inachevée, notamment en ce que sa performativité ne va pas jusqu’à la responsabilité assumée de l’énonciateur. Il s’agit de tenter d’identifier les lignes de fracture qui traversent le sujet d’énonciation journalistique et, avec elles, le partage de responsabilités qui en est induit. Notre ambition est d’établir un lien entre la division propre à l’énonciation journalistique et un questionnement sur le partage de l’espace et de la parole publics, ce qui suppose de se demander, notamment en intégrant à l’analyse le concept derridien de « téléiopoièse », où et comment se situe, dans cette disposition, la participation du destinataire.

This paper aims to evaluate Senegalese consumers' willingness-to-pay (WTP) for local fresh milk-based products, in opposition to the ones produced with imported powder. Using data from a choice-based-conjoint analysis conducted on 400 households in the region of Dakar, we evaluate the premium that consumers are willing to pay for fresh raw material (rather than powder) in the composition of sour milk. Based on an Ordered Probit Model, the results show evidence for a positive WTP for fresh raw material, which may be seen as a strong indication of preference for local products. This WTP greatly depends on the characteristics of the households. Wealthier households are willing to pay more than the medium households, while big households are ready to pay much less than the base category ones. Obviously, some niche markets exist, that producers may target to sell the local milk-based dairy products. However, more information has to be provided about the composition of dairy products, as consumers are not currently able to distinguish both types of raw material, even if they are willing to pay more for one of them. In spite of some restrictions about the presence of a potential "hypothetical bias" due to the nature of the data, this study gives a rst insight of consumers' preferences for local milk-based dairy products.

En forte croissance ces dernières années, l’intérêt du milieu académique pour les réseaux d’innovation aborde sous des angles divers les différents enjeux que soulève cette forme de regroupement d’organisations et de structure partenariale. Dans ce cadre, notre contribution entend plus spécifiquement interroger la question de la gouvernance – et de la coordination des activités qui y sont menées – en vigueur au sein d’une forme particulière de réseaux inter-organisationnels : les pôles de compétitivité. La gouvernance de ce type de réseaux d’innovation réunissant des catégories d’acteurs hétérogènes mus par des intérêts contrastés, les formes qu’elle est concrètement susceptible de prendre dans les faits, les difficultés qu’elle soulève au quotidien ainsi que les dynamiques qu’elle engendre en termes de synergies collaboratives constituent autant de champs de recherche en pleine émergence que nous entendons compléter par l’examen d’une question centrale dans le succès de ce type d’initiatives : les rôles et missions qu’y joue la fonction de coordination. En ce sens, nous questionnons l’importance du rôle de la fonction de coordination dans la gestion des relations entre acteurs, dans la conciliation de leurs intérêts ainsi que dans l’élaboration d’une vision stratégique commune et partagée pour le partenariat. Ce faisant, nous entendons examiner le côté « tercéisant » des initiatives mises en place en la matière, à savoir le processus de réflexivité et de déplacement identitaire qu’insuffle la fonction de coordination au niveau du réseau pour permettre l’institutionnalisation de nouvelles pratiques collaboratives et arriver à la satisfaction conjointe des intérêts respectifs des différents partenaires. Outre un apport analytique basé sur l’examen de trois études de cas, notre réflexion entend également suggérer différentes recommandations quant aux dynamiques de gouvernance à privilégier dans le cadre des projets des pôles de compétitivité et aux tâches effectives de gestion et de coordination à y assurer pour en favoriser le succès.

In addition, we test the direction of potential causality between nancial and economic development. Our results conclude to the existence of a single cointegrating vector between nancial development and growth and of causality going from nancial development to economic growth.

In this article, we evaluate, from the point of view of banks, the potential of articulations between commercial banks and microfinance institutions (MFIs) in Cameroun in terms of financing of the rural and the micro, small and medium enterprises (MSMEs). Furthermore, we seek to define the best form of partnership between the two types of institutions. The results obtained suggest that the articulations between banks and MFIs can potentially be beneficial to all stakeholders (banks, MFIs but also recipients). This study also highlights the fact that these articulations can be even more beneficial if national commercial banks, under the Cameroonian law in our case, participate rather than branches of foreign banking groups. Indeed, our research reveals that through these partnerships, from their cultural proximity and their propensity to take more risks, national commercial banks will more likely offer either directly or indirectly (through MFIs) more adapted financial products and services to both the rural and the MSMEs’ segments. The question of knowing if a better form of partnership between commercial banks and MFIs exists, results suggest that there is no better form of partnership as such; that the best form depends on the MFI’s development stage and that in any case this partnership should privilege a national commercial bank rather than a branch of a foreign bank. Even if the foreign banks’ contest might be necessary at a given stage of the process, the results make it also possible to consider a new model of interactions implying Microfinance investment vehicles and national commercial banks. This model would have the advantage to help mitigate risks that those vehicles perceive when deciding to directly invest in MFIs. [less ▲]

Classic financial agency theory recommends compensation through stock options rather than shares to induce risk neutrality in otherwise risk averse agents. In an experiment, we find that subjects acting as executives do also take risks that are excessive from the perspective of shareholders if compensated through options. Compensation through restricted company stock reduces the uptake of excessive risks. Even under stock-ownership, however, experimental executives continue to take excessive risks—a result that cannot be accounted for by classic incentive theory. We develop a basic model in which such risk-taking behavior is explained based on a richer array of risk attitudes derived from Prospect Theory. We use the model to derive hypotheses on what may be driving excessive risk taking in the experiment. Testing those hypotheses, we find that most of them are indeed borne out by the data. We thus conclude that a prospect-theory-based model is more apt at explaining risk attitudes under different compensation regimes than traditional principal-agent models grounded in expected utility theory.

In a series of experiments conducted in Belgium (Wallonia and Flanders), France and the Netherlands, we compare behavior regarding tax evasion and welfare dodging, with and without information about others’ behavior. Subjects have to decide between a ‘registered’ income, the realization of which will be known to the tax authority for sure, and an ‘unregistered’ income that will only be known with some probability. This unregistered income comes from self-employment in the Tax treatment and from black labor supplementing some unemployment compensation in the Welfare treatment. Subjects have then to decide on whether reporting their income or not, knowing the risk of detection. The results show that (i) individuals evade more in the Welfare treatment than in the Tax treatment; (ii) many subjects choose an option that allows for tax evasion or welfare fraud but report their income honestly anyway; (iii) examples of low compliance tend to increase tax evasion while examples of high compliance exert no influence; (iv) tax evasion is more frequent in France and the Netherlands; Walloons evade taxes less than the Flemish. There is no cross-country difference in welfare dodging. [less ▲]

En forte croissance ces dernières années, l’intérêt du milieu académique pour les pôles de compétitivité aborde sous des angles divers les enjeux que représente cette nouvelle forme de regroupement territorialisé d’organisations. En particulier, la gouvernance de ce type de réseaux d’innovation réunissant des catégories d’acteurs hétérogènes, les formes qu’elle est concrètement susceptible de prendre dans les faits, les difficultés qu’elle soulève au quotidien ainsi que les dynamiques qu’elle engendre en termes de synergies collaboratives constituent des champs de recherche en pleine émergence, renforcés par la pression des pouvoirs publics qui attendent des pôles de compétitivité qu’ils gèrent au mieux les ressources financières qui leur sont octroyées et veillent à rentabiliser celles-ci dans l’intérêt de la collectivité. Dans ce cadre, notre contribution entend plus particulièrement interroger la question de la coordination de cette forme de partenariats inter-organisationnels que sont les pôles de compétitivité et cerner les dynamiques à l’œuvre dans ce type de structure collaborative. En dépassant le stade d’une fonction de coordination placée sous la seule responsabilité des « porteurs de projets », nous nous intéressons aux efforts que consentent les parties prenantes – internes et externes – des pôles de compétitivité pour arriver à la satisfaction conjointe de leurs intérêts respectifs. En ce sens, nous questionnons l’éventuel « déplacement identitaire » qu’opèrent les acteurs pour favoriser le succès des pôles et des projets qui y sont développés ainsi que l’influence que revêt dans ce cadre la fonction de coordination du réseau. Renvoyant au concept de « tercéisation », qui illustre le processus de réflexivité et de réflectivité qu’opèrent les acteurs pour concevoir et institutionnaliser de nouvelles pratiques, ces dynamiques sont étudiées au cours de notre propos à la lumière des enseignements tirés des pôles de compétitivité promus en Belgique dans le cadre du Plan Marshall, initiative mise en œuvre par le Gouvernement de la Région Wallonie-Bruxelles pour renforcer les processus d’innovation des entreprises et le développement économique de la Région.

Depuis l’émergence, au début des années septante, du terrorisme d’extrême gauche en Allemagne, le pays est secoué de façon cyclique par des polémiques relatives aux « années de plomb », des conflits et débats violents qui opposent d'ordinaire l'Etat et certains organes médiatiques atlantistes, conservateurs ou d'extrême droite, à la foule de ceux qui, pour de multiples raisons, désapprouvent la guerre menée par l’Etat contre les terroristes. Cette polarisation affecte rapidement les champs de la philosophie, du droit, des sciences historiques, politiques et sociales ou encore de la littérature, du cinéma et de l’art contemporain en général. Or il est frappant de constater que, hier comme aujourd’hui, dans les médias, ces conflits, débats et polémiques s’articulent moins autour de questions politiques de fond, qu’autour de faits, difficiles à avérer, et surtout de leurs représentations, essentiellement photographiques et cinématographiques, qui alimentent les accusations et les attaques de l’un ou l’autre camp, bon nombre d’images servant même simultanément d’argument à charge aux deux camps. Afin de déterminer la part de "responsabilité" de la photographie dans ces incessants conflits, et d'imaginer corolairement une échappatoire à son rôle polémiste, cette communication s'intéresse plus particulièrement à la polémique provoquée par les débats autour des conditions de détention des prisonniers de la RAF.

L’objectif de cette contribution est de s’interroger sur les potentialités de développement de la filière bois-énergie à l’échelle européenne et de chercher à voir si c’est une réelle alternative aux énergies fossiles. À cette fin, nous avons tenté d’abord de mieux cerner la ressource, puis de mesurer l’importance du bois-énergie et son évolution récente à la fois globalement pour l’UE à 27 et par pays en cherchant à comprendre les disparités entre ces derniers. Enfin, dans une troisième partie, nous répondons aux quatre questions suivantes : quel est le potentiel réellement mobilisable pour ne pas épuiser la ressource ? Quel est son réel bilan environnemental et son impact sur la santé ? Quel est son impact sur l’économie locale d’une région et sur la gestion de la forêt et du territoire proche ?

Ever since the creation of the General Court (“GC”), the effectiveness of judicial review in European Union (“EU”) competition cases has sparked intense scholarly debates. This paper seeks to further contribute to this discussion in three ways. First, it devotes some space to fundamental, yet often overlooked questions, such as the goals or functions of judicial review and why judicial review of administrative decisions is important; particularly so in competition law matters. Second, this paper attempts to throw some empirical light on the GC’s judicial review of European Commission (“Commission”) decisions in the field of competition law. Third, it places a specific emphasis on the particular situation of abuse of dominance law, where the GC has exercised its judicial review power with more restraint than in other areas of competition law (such as restrictive agreements and mergers). With these goals in mind, this paper follows a five-stage progression. First, on the basis of a survey of the relevant legal, economic and political science literature, it defines the functions of judicial review and identifies a set of indicators which can be used to assess the performance of the GC’s judicial scrutiny (Part I). Second, it explains why judicial review in EU competition law cases is of critical importance notably given the institutional and procedural deficiencies of the EU enforcement structure (Part II). Third, it discusses the nature and standard of review currently applied by the GC with a particular focus on the degree to which the GC is willing to review “complex economic matters” (Part III). Fourth, it provides some quantitative data on the case-law of the GC to assess whether several goals or functions attributed to judicial review by the scientific literature are met (Part IV). Finally, this paper takes a closer look at the (controversial) case-law of the GC in the field of Article 102 of the Treaty on the Functioning of the European Union (“TFEU”) (Part V). [less ▲]

We present a comparative study of the thermal emission of the transiting exoplanets WASP-1b and WASP-2b using the Spitzer Space Telescope. The two planets have very similar masses but suffer different levels of irradiation and are predicted to fall either side of a sharp transition between planets with and without hot stratospheres. WASP-1b is one of the most highly irradiated planets studied to date. We measure planet/star contrast ratios in all four of the IRAC bands for both planets (3.6-8.0um), and our results indicate the presence of a strong temperature inversion in the atmosphere of WASP-1b, particularly apparent at 8um, and no inversion in WASP-2b. In both cases the measured eclipse depths favor models in which incident energy is not redistributed efficiently from the day side to the night side of the planet. We fit the Spitzer light curves simultaneously with the best available radial velocity curves and transit photometry in order to provide updated measurements of system parameters. We do not find significant eccentricity in the orbit of either planet, suggesting that the inflated radius of WASP-1b is unlikely to be the result of tidal heating. Finally, by plotting ratios of secondary eclipse depths at 8um and 4.5um against irradiation for all available planets, we find evidence for a sharp transition in the emission spectra of hot Jupiters at an irradiation level of 2 x 10^9 erg/s/cm^2. We suggest this transition may be due to the presence of TiO in the upper atmospheres of the most strongly irradiated hot Jupiters. [less ▲]

Au cours de la dernière décennie, la présence dans la presse économique de cas de restructurations et de licenciements économiques toujours plus nombreux a fini par nous habituer au fait que ces phénomènes font désormais partie du processus normal d’évolution de l’entreprise. Plus récemment, la crise économique mondiale a eu, et a toujours, un impact important sur les entreprises belges, provoquant une vague de restructurations et de licenciements sans précédent. Le présent rapport est divisé en cinq parties : le contexte, l’anticipation (ou l’amont), les dynamiques de restructurations, la mise en œuvre (ou l’aval) et les acteurs impliqués. Dans le premier chapitre, nous proposons un aperçu du contexte économique et social belge afin de permettre au lecteur de comprendre le cadre dans lequel prennent part les phénomènes de restructuration. Le deuxième chapitre présente les principales mesures qui relèvent de l’anticipation des restructurations, certaines existant de longue date en Belgique alors que d’autres sont plus récentes, voire spécifiques aux mesures prises par les pouvoirs publics pour contrer la crise actuelle. Le troisième chapitre se concentre sur les différentes dynamiques de restructuration d’entreprises et le cadre légal qui les régit. Le quatrième chapitre développe les principales mesures de mise en œuvre des restructurations, qu’elles soient, ici aussi, présentes de longue date ou spécifiques aux « mesures de crises ». La quantification et l’évaluation des mesures présentées dans ce rapport font l’objet d’un point spécifique, en conclusion de chacun de ces 3 derniers chapitres. Enfin, un cinquième chapitre présente de manière succincte les différents acteurs impliqués dans les processus de restructuration. [less ▲]

Fair trade (FT) organisations have been quite early taken as examples of social enterprises (SE) and have contributed to the shaping of the SE concept. The goal of this article is to examine more deeply, both at a conceptual and at an empirical level, to what extent FT organisations can be considered as social enterprises. First, we introduce different theoretical frameworks of SE and examine FT in the context of each of these frameworks. In a second step, we use an empirical study on fair trade social enterprises (FTSEs) across four European countries to illustrate and deepen the links between FT and SE, focusing on the goals and the governance structures of FTSEs. It appears that all FTSEs combine in some way economic, social and sometimes also political goals. FTSEs are thus in line with the "hybrid-goal" nature of SEs. FTSEs' governance is also quite specific and often innovative in terms of organisational architecture and stakeholders' involvement. Some FTSEs are closer to the European – participatory – approach of social enterprise, while others are closer to US – individual – approaches. Finally, the governance structures of FTSEs seem to reflect quite well their goal mix. This article provides a more solid basis for the often implicit link between FT and SE. Future researches could use our work to explore specific topics of the SE literature (e.g. stakeholders' involvement) in the context of FT. The FT example could also be used to examine further the shifting boundaries of the SE reality. The originality of this article is to apply the SE concept to a specific field and to show how, within this field, there is at the same time (1) a diversity of organisations, reflecting the diversity of SE approaches and (2) a range of specific features (especially in terms of goal mix and governance) distinguishing SEs from other types of organisations operating in the same field.

n this paper, wee propose a model for regulatory capture that is based on information transmission and asymmetric information. In a three-tier model, a regulator is charged by a political principal to provide a signal for the type of a regulated firm. Only the firm can observe his type and the production of a correlated signal with a given accuracy is costly for the regulator. The firm can costlessly provide an alternative signal of lower accuracy that is presented to the regulator. In a self-enforcing equilibrium, the regulator transmits the firm-produced signal, internalizes its own savings in information cost and the firm enjoys higher information rents. The main feature of soft capture is that it is not based on a reciprocity of favors but on a congruence of interests between the firm and the regulator. [less ▲]

In this paper, we investigate the convergence process within the European Union (27 countries). More particularly, we study the convergence process of the new entrants from Central and Eastern Europe and of the 15 Western countries between 1990 and 2007. Applying a panel approach to the convergence equation derived by Mankiw et al. (1992) from the Solow model, we highlight the existence of heterogeneity in the European Union and show that new entrants and former members of the European Union can be seen as belonging to significantly differ- ent groups of convergence. The existence of heterogeneity in the European Union or the Eurozone might affect their stability as the recent Greece’s sovereign debt crisis illustrates it. [less ▲]
