A new highly penetrant form of obesity due to deletions on chromosome 16p11.2.

Obesity has become a major worldwide challenge to public health, owing to an interaction between the Western 'obesogenic' environment and a strong genetic contribution. Recent extensive genome-wide association studies (GWASs) have identified numerous single nucleotide polymorphisms associated with obesity, but these loci together account for only a small fraction of the known heritable component. Thus, the 'common disease, common variant' hypothesis is increasingly coming under challenge. Here we report a highly penetrant form of obesity, initially observed in 31 subjects who were heterozygous for deletions of at least 593 kilobases at 16p11.2 and whose ascertainment included cognitive deficits. Nineteen similar deletions were identified from GWAS data in 16,053 individuals from eight European cohorts. These deletions were absent from healthy non-obese controls and accounted for 0.7% of our morbid obesity cases (body mass index (BMI) >or= 40 kg m(-2) or BMI standard deviation score >or= 4; P = 6.4 x 10(-8), odds ratio 43.0), demonstrating the potential importance in common disease of rare variants with strong effects. This highlights a promising strategy for identifying missing heritability in obesity and other complex traits: cohorts with extreme phenotypes are likely to be enriched for rare variants, thereby improving power for their discovery. Subsequent analysis of the loci so identified may well reveal additional rare variants that further contribute to the missing heritability, as recently reported for SIM1 (ref. 3). The most productive approach may therefore be to combine the 'power of the extreme' in small, well-phenotyped cohorts, with targeted follow-up in case-control and population cohorts.

Informational matching

This paper analyzes the problem of matching heterogeneous agents in aBayesian learning model. One agent gives a noisy signal to another agent,who is responsible for learning. If production has a strong informationalcomponent, a phase of cross-matching occurs, so that agents of low knowledgecatch up with those of higher one. It is shown that:(i) a greater informational component in production makes cross-matchingmore likely;(ii) as the new technology is mastered, production becomes relatively morephysical and less informational;(iii) a greater dispersion of the ability to learn and transfer informationmakes self-matching more likely; and(iv) self-matching leads to more self-matching, whereas cross-matching canmake less productive agents overtake more productive ones.

Assesing the political viability of labour market reform: The case of employment protection

We analyze the political support for employment protection legislation.Unlike my previous work on the same topic, this paper pays a lot ofattention to the role of obsolescence in the growth process.In voting in favour of employment protection, incumbent employeestrade off lower living standards (because employment protectionmaintains workers in less productive activities) against longer jobduration. The support for employment protection will then depend onthe value of the latter relative to the cost of the former. Wehighlight two key deeterminants of this trade-off: first, the workers'bargaining power, second, the economy's growth rate-more preciselyits rate of creative destruction.

Dans le cadre de l´initiative de la CEDEAO, Cap Vert c´est lance dans l‟élaboration de la présente sub-composante que s‟inscrit dans le cadre de l‟appui à la Formulation et mise en oeuvre d‟un Programme National d‟ Investissement Agricole (PNIA) pour la mise en oeuvre du PDDAA/NEPAD. Le document de stratégie de réduction de la pauvreté (DECRP) du pays indique la sécurité alimentaire et la garantie de la cohésion sociale en milieu rural comme les axes stratégiques centraux et dans le cadre des stratégies nationales de lutte contre la pauvreté et de sécurité alimentaire, le gouvernement du Cap-Vert a adoptée et mis en oeuvre un certain nombre de programmes pour lever les contraintes multiples auxquelles le pays est confronté, et relancer le secteur agricole. La vision stratégique de développement à court et moyen termes du Gouvernement est présentée dans le document intitulé „Grandes Options du Plan‟, basés sur les orientations suivantes: a. Promouvoir la bonne gouvernance comme facteur de développement, en réformant l‟Etat, en intensifiant la démocratie et en renforçant la citoyenneté, b. Promouvoir la capacité entrepreneur, la compétitivité et la croissance ; élargir la base productive, c. Développer le capital humain et orienter le système d‟enseignement/ formation vers les domaines prioritaires de développement, d. Promouvoir une politique globale de développement social, luttant contre la pauvreté et renforçant la cohésion et la solidarité, e. Développer des infrastructures de base et économiques et promouvoir l‟aménagement du territoire pour un développement équilibré. Étant un secteur important de l‟activité économique et sociale du Cap-Vert, l‟agriculture doit jouer les rôles fondamentaux ci-après: améliorer les conditions d‟existence durable des ruraux par la promotion d‟une approche intégrée du développement des communautés rurales, en misant sur le développement agrosylvo-pastoral comme axe fondamental,  renforcer la sécurité alimentaire des populations rurales et urbaines, l‟approvisionnement du marché interne et le développement du secteur touristique en plein essor. Le gouvernement préconise la modernisation de l‟agriculture, la déconcentration des services et institutions d‟appui a la production, la promotion de la compétitivité dans l‟agriculture et la pêche, notamment par l‟élargissement et la diversification de la base productive. La modernisation du secteur agricole et le développement rural par l‟introduction de nouvelles technologies pour l‟intensification et la diversification, doivent assurer le renforcement du tissu économique rural. A cet effet, la croissance durable de la production agricole dépend prioritairement de mesures de rationalisation et d‟optimalisation de l‟utilisation de l‟eau d‟irrigation. Les orientations devront privilégier le montage de mécanismes d‟investissements dirigés vers une nouvelle agriculture spécialisée, complétée par la formation agro-alimentaire, et le développement d‟autres secteurs stratégiques et, particulièrement le tourisme. Les orientations stratégiques pour le secteur agricole, sont identifiées comme suit :  la réorganisation de la production pluviale (végétale et animale) en vue de renforcer la capacité productive et la protection de ces zones,  la diversification des activités de production et la prestation des services en milieu rural, élargissant ainsi la base productive, en accord avec les grandes orientations du Plan Stratégique,  le développement et la valorisation de l‟écotourisme.

Importância da Horticultura para a Segurança Alimentar em Cabo Verde - Estudo de Caso na Ilha do Fogo

A agricultura cabo-verdiana é caracterizada pela baixa e irregular produtividade e não consegue produzir mais do que 20% das necessidades alimentares do país, sendo que a insegurança alimentar e a pobreza estão intimamente ligadas à fraqueza da base produtiva. A horticultura é considerada como um dos sectores mais rentáveis, com um papel importante na segurança alimentar e no orçamento das famílias. A presente dissertação tem como objectivo principal o estudo da importância da horticultura no rendimento e segurança alimentar das famílias, através da venda e consumo de produtos hortícolas. Foi realizado um estudo de caso às familias com e sem produção hortícola na ilha do Fogo em Cabo Verde e verificou-se que os agregados com regadio têm um rendimento anual bastante superior aos rendimentos auferidos pelos agregados sem regadio e a horticultura teve um contributo notável na formação desse rendimento. A nível da alimentação verificou-se que os agregados com regadio tem um consumo calórico superior aos agregados sem regadio. Verificou-se igualmente que os agregados com regadio tem uma alimentação mais diversificada, quer pela frequência de consumo diária de produtos hortícolas e frutas quer pelo consumo per capita dos mesmos.

Failure to collude in the presence of asymmetric information

In this paper, we design the optimal contract when two agents can collude under asymmetric information. They have correlated types, produce complementary inputs and are protected by limited liability. Therefore, a joint manipulation of reports allows them to internalize informational and productive externalities. We show that by taking advantage of the transaction costs created by asymmetric information, even though they collude, the principal can achieve the outcome without collusion regardless of the sign and the degree of correlation. In particular, the principal can implement a non-monotonic quantity schedule in a collusion-proof way while this is impossible if collusion occurs under complete information.

Organizational capital and employment fluctuations

In this paper I present a model in which production requires two types of labor inputs: regular productive tasks and organizational capital, which is accumulated by workers performing organizational tasks. By allocating more workers from organizational to productive tasks, firms can temporarily increase production without hiring. The availability of this intensive margin of labor adjustment, in combination with adjustment costs along the extensive margin (search frictions, firing costs, training costs), makes it optimal to delay employment adjustments. Simulations indicate that this mechanism is quantitatively important even if only a small fraction of workers perform organizational tasks, and explains why the hiring rate is persistent and why employment is slow to recover after the end of a recession.

The political economy of employment protection

This paper develops a model of job creation and job destruction in agrowing economy with embodied technical progress, that we use toanalyze the political support for employment protection legislationssuch as the ones that are observed in most European countries.We analyze the possibility of Condorcet cycles due to the fact thatworkers about to become unemployed prefer both an increase and areduction in firing costs over the status quo. Despite this problem, we show the existence of local, and sometimes global majority winners.In voting in favour of employment protection, incumbent employeestrade off lower living standards (because employment protectionmaintains workers in less productive activities) against longer job duration. We show that the gains from, and consequently the politicalsupport for employment protection (as defined by maximunjob tenure) are larger, the lower the rate of creative destruction and the largerthe worker's bargaining power. Numerical simulations suggest a hump-shaped response of firing costs to these variables, as well as negative impact of exogeneous turnover on employment protection.

Draft environmental report on Cape Verde

Faced with recurrent drought and famine during five centuries of human occupation, the small and densely populated Cape Verde Islands have a history of severe environmental problems. The arid climate and steep, rocky terrain provide scant resources for traditional subsistance farming under the best conditions, and in years of low rainfall the failure of rainfed crops causes massive food shortages. Agricultural use of steep slopes where rainfall is highest has led to soil erosion, as has removal of the island's vegetation for fuel and livestock. Pressure on the vegetation is particularly severe in dry years. International aid can provide relief from famine, and the introduction of modern agricultural and conservation techniques can improve the land and increase yield, but it is unlikely that Cape Verde can ever be entirely self -sufficient in food. Ultimately, the solution of Cape Verde's economic and environmental problems will probably require the development of productive urban jobs so the population can shift away from the intensive and destructive use of land for subsistance farming. In the meantime, the people of Cape Verde can best be served by instituting fundamental measures to conserve and restore the land so that it can be used to its fullest potential. The primary environmental problems in Cape Verde today are: 1. Soil degradation. Encouraged by brief but heavy rains and steep slopes, soil erosion is made worse by lack of vegetation. Soils are also low in organic matter due to the practice of completely removing crop plants and natural vegetation for food, fuel or livestock feed. 2. Water shortage. Brief and erratic rainfall in combination with rapid runoff makes surface water scarce and difficult to use. Groundwater supplies can be better developed but capabilities are poorly known and the complex nature of the geological substrate makes estimation difficult. Water is the critical limiting factor to the agricultural capability of the islands. 3. Fuel shortage. Demand for fuel is intense and has resulted in the virtual elimination of native vegetation. Fuelwood supplies are becoming more and more scarce and costly. Development of managed fuelwood plantations and alternate energy sources is required. 4. Inappropriate land use. Much of the land now used for raising crops or livestock is too steep or too arid for these purposes, causing erosion and destruction of vegetation. Improving yield in more appropriate areas and encouraging less damaging uses of the remaining marginal lands can help to alleviate this problem.

Adjustment to target capital, finance and growth

Does financial development result in capital being reallocated more rapidly to industries where it is most productive? We argue that if this was the case, financially developed countries should see faster growth in industries with investment opportunities due to global demand and productivity shifts. Testing this cross-industry cross-country growth implication requires proxies for (latent) global industry investment opportunities. We show that tests relying only on data from specific (benchmark) countries may yield spurious evidence for or against the hypothesis. We therefore develop an alternative approach that combines benchmark-country proxies with a proxy that does not reflect opportunities specific to a country or level of financial development. Our empirical results yield clear support for the capital reallocation hypothesis.

Intergenerational justice when future worlds are uncertain

Let there be a positive (exogenous) probability that, at each date, the human species will disappear.We postulate an Ethical Observer (EO) who maximizes intertemporal welfare under thisuncertainty, with expected-utility preferences. Various social welfare criteria entail alternativevon Neumann- Morgenstern utility functions for the EO: utilitarian, Rawlsian, and an extensionof the latter that corrects for the size of population. Our analysis covers, first, a cake-eating economy(without production), where the utilitarian and Rawlsian recommend the same allocation.Second, a productive economy with education and capital, where it turns out that the recommendationsof the two EOs are in general different. But when the utilitarian program diverges, thenwe prove it is optimal for the extended Rawlsian to ignore the uncertainty concerning the possibledisappearance of the human species in the future. We conclude by discussing the implicationsfor intergenerational welfare maximization in the presence of global warming.

Generating global brand equity through corporate social responsibility to key stakeholders

In this paper we argue that corporate social responsibility (CSR) to various stakeholders(customers, shareholders, employees, suppliers, and community) has a positive effect on globalbrand equity (BE). In addition, policies aimed at satisfying community interests help reinforcecredibility to social responsible polices with other stakeholders. We test these theoreticalcontentions using panel data comprised of 57 global brands originating from 10 countries (USA,Japan, South Korea, France, UK, Italy, Germany, Finland, Switzerland and the Netherlands) forthe period 2002 to 2008. Our findings show that CSR to each of the stakeholder groups has apositive impact on global BE. In addition, global brands that follow local social responsibilitypolicies over communities obtain strong positive benefits in terms of the generation of BE, as itenhances the positive effects of CSR to other stakeholders, particularly to customers. Therefore,for managers of global brands it is particularly productive for generating brand value to combineglobal strategies with the satisfaction of the interests of local communities.
