décisions d’une société importante, décisions qui reflètent les choix « du peuple, par le peuple, pour le peuple ». Ceci est, dans une acception générale, le sujet de la théorie du « choix social », et il inclut, à l’intérieur de son vaste champ, des problèmes divers ayant la caractéristique commune de mettre en relation des jugements sociaux et des décisions collectives avec les opinions et les intérêts des individus qui composent la société ou le groupe. S’il est une question centrale qui peut être envisagée

populations (Peddison et al 1990; Walton and Seddon, 1994). There has been a growing interest in recent years in the considerable potential of agriculture in and around the large cities of Sub-Saharan African (SSA), as one possible element in solving the problem of future food supply. The International Food Policy Research Institute opined that “One way to help ward off hunger among low-income households of the future may be through ‘Urban Agriculture’, the farming of small plot of land available in urban

rational individual with an imperfect knowledge of his own time preferences. At the time of choosing, the individual who seeks cognitive consistency reconciles several successive cognitions: his normative preference – represented by the discounted utility model (DU) - that he perceives with more or less precision and one or several myopic preferences imposed by the context of the decision. We handle first the general case of a myopic preference for the most immediate reward. This preference is generated

comme une caractéristique permanente, alors que la dominance, qui reste toujours une donnée statistique, l’individu pouvant constamment basculer d’un état dans un autre, remet en question le concept même de trait. Ces renversements posent de plus un problème crucial pour tous les protocoles expérimentaux : en tant que variable parasite ils entraînent des difficultés dans l’appariement des groupes et peuvent fausser les conditions expérimentales, si ces dernières provoquent elles-mêmes des renversements

passage de l’une à l’autre. Aussi, lorsque la volonté est prête à être mobilisée pour un choix, c’est que la transition en tant que telle est achevée et que les désirs sont, par conséquent, comparables. Il n’y a donc pas, à strictement parler, de problème relatif à l’incomplétude des préférences, mais plutôt au passage d’un contexte de choix où les préférences sont complètes, à un autre contexte de choix où les préférences sont différentes et, là encore, complètes. En revanche, rien à ce stade de

easy to render the criteria for Fair Trade operational in either the Northern or Southern hemispheres; the 2005 IFAT conference heard complaints from producers and buyers alike. In the North, people complain of late or missing deliveries and quality problems. In the South, the complaints concern cancelled orders, advance financing that is increasingly difficult to obtain or arrives late, late payment, lower prices paid, the aggressive attitude of buyers and attempts to haggle about prices. The charge

pricing problems for contingent claims. Definition 2.7 A contingent claim (financial derivative) is any stochastic variable X of the form X = (d) = O. Our main problem is now to determine the "fair" price, if such an object exists at all, for a given contingent claim X. If we denote the price of X at time t by TI(t; X), then it can be seen that at time t = 1 the problem is easy to solve. In order to avoid arbitrage we must (why?) have II(l;X) = X, and the hard part of the problem is to determine

the farmers understand what the customers want. (Tesco CSR, 2008) Tesco’s customers belong to a variety of social classes. The AB grouping accounts for 19% of spend, C1-28%, C2-21%, D-15% AND E-17%. (Scottish Food and Drink, 2009) 1.8 Research Problems Tesco is a very large and powerful business that sells more than a fifth of intensively produced chicken in the UK and only introduces changes based on the strong consumer demand. Company’s views are against phasing out of intensive farmed chicken

to assemble many contiguous parcels, such as for a road, acquisition by purchase might be stymied by hold-out problems, making the power to take socially advantageous. Assuming that there is a reason for the state to take property, a requirement to pay compensation may curb problems of overzealousness or abuse of authority by public officials, yet it may also exacerbate potential problems of too little public activity, because public authorities do not directly receive the benefits of takings (Kaplow
