Stated preference methods and landscape ecology indicators: an example of transdisciplinarity in landscape economic valuation

This paper addresses the representation of landscape complexity in stated preferences research. It integrates landscape ecology and landscape economics and conducts the landscape analysis in a three-dimensional space to provide ecologically meaningful quantitative landscape indicators that are used as variables for the monetary valuation of landscape in a stated preferences study. Expected heterogeneity in taste intensity across respondents is addressed with a mixed logit model in Willingness to Pay space. Our methodology is applied to value, in monetary terms, the landscape of the Sorrento Peninsula in Italy, an area that has faced increasing pressure from urbanization affecting its traditional horticultural, herbaceous, and arboreal structure, with loss of biodiversity, and an increasing risk of landslides. We find that residents of the Sorrento Peninsula would prefer landscapes characterized by large open views and natural features. Residents also appear to dislike heterogeneous landscapes and the presence of lemon orchards and farmers' stewardship, which are associated with the current failure of protecting the traditional landscape. The outcomes suggest that the use of landscape ecology metrics in a stated preferences model may be an effective way to move forward integrated methodologies to better understand and represent landscape and its complexity.

Demand Response Programs Definition Using Demand Price Elasticity to Define Consumers Aggregation for an Improved Remuneration Structure

The positioning of the consumers in the power systems operation has been changed in the recent years, namely due to the implementation of competitive electricity markets. Demand response is an opportunity for the consumers’ participation in electricity markets. Smart grids can give an important support for the integration of demand response. The methodology proposed in the present paper aims to create an improved demand response program definition and remuneration scheme for aggregated resources. The consumers are aggregated in a certain number of clusters, each one corresponding to a distinct demand response program, according to the economic impact of the resulting remuneration tariff. The knowledge about the consumers is obtained from its demand price elasticity values. The illustrative case study included in the paper is based on a 218 consumers’ scenario.

Remuneration Structure Definition for Distributed Generation Units and Demand Response Participants Aggregation

The implementation of competitive electricity markets has changed the consumers’ and distributed generation position power systems operation. The use of distributed generation and the participation in demand response programs, namely in smart grids, bring several advantages for consumers, aggregators, and system operators. The present paper proposes a remuneration structure for aggregated distributed generation and demand response resources. A virtual power player aggregates all the resources. The resources are aggregated in a certain number of clusters, each one corresponding to a distinct tariff group, according to the economic impact of the resulting remuneration tariff. The determined tariffs are intended to be used for several months. The aggregator can define the periodicity of the tariffs definition. The case study in this paper includes 218 consumers, and 66 distributed generation units.

Vertical R&D Sprillovers, Cooperation, Market Structure, and Innovation.

This paper studies vertical R&D spillovers between upstream and downstream firms. The model incorporates two vertically related industries, with horizontal spillovers within each industry and vertical spillovers between the two industries. Four types of R&D cooperation are studied : no cooperation, horizontal cooperation, vertical cooperation, and simultaneous horizontal and vertical cooperation. Vertical spillovers always increase R&D and welfare, while horizontal spillovers may increase or decrease them. The comparison of cooperative settings in terms of R&D shows that no setting uniformly dominates the others. Which type of cooperation yields more R&D depends on horizontal and vertical spillovers, and market structure. The ranking of cooperative structures hinges on the signs and magnitudes of three competitive externalities (vertical, horizontal, and diagonal) which capture the effect of the R&D of a firm on the profits of other firms. One of the basic results of the strategic investment literature is that cooperation between competitors increases (decreases) R&D when horizontal spillovers are high (low); the model shows that this result does not necessarily hold when vertical spillovers and vertical cooperation are taken into account. The paper proposes a theory of innovation and market structure, showing that the relation between innovation and competition depends on horizontal spillovers, vertical spillovers, and cooperative settings. The private incentives for R&D cooperation are addressed. It is found that buyers and sellers have divergent interests regarding the choice of cooperative settings and that spillovers increase the likelihood of the emergence of cooperation in a decentralized equilibrium.

Standardized Latin and Medieval Economic Growth

Traditional explanations for Western Europe's demographic growth in the High Middle Ages are unable to explain the rise in per-capita income that accompanied observed population changes. Here, we examine the hypothesis that an innovation in information technology changed the optimal structure of contracts and raised the productivity of human capital. We present historical evidence for this thesis, offer a theoretical explanation based on transaction costs, and test the theory's predictions with data on urban demographic growth. We find that the information-technology hypothesis significantly increases the capacity of the neoclassical growth model to explain European economic expansion between 1000 and 1300.

Ordered Model Processes, Reference Declaration And The Economic Organization: Implications For A Balanced Scorecard Contextual Framework

Les Tableaux de Bord de la Performance ont été acclamés avec raison depuis leur introduction en 1992, mais les intellectuels continuent encore à étudier leurs aspects pragmatiques. Ce papier contribue à la littérature sur les Tableaux de Bord de la Performance, tout d’abord, en offrant une explication logique quant à leur succès et ensuite, en présentant un cadre de travail contextuel de tableaux de bord de la performance pour une structure de gestion hiérarchisée. Le cadre de travail contextuel réforme la perspective d’apprentissage et de croissance du tableau de bord de la performance (i) en effectuant la transition de référence (subjective/objective), et (ii) en reconnaissant que la Perspective d’Apprentissage et de Croissance implique avant tout une incidence de formulation stratégique d’une extra-entité. Le transfert de l’incidence (intra-entité/extra-entité) réconcilie l’évolution de la position de politique de gestion non ordonnée [Contenu: (Contenu: Contexte): Contexte] qu’est la Perspective d’Apprentissage et de Croissance Concomitante. Le cadre de travail supplante également les Perspectives des Tableaux de Bord de la Performances développés par Kaplan et Norton en ajoutant la perspective de politique sociale qui manquait. La perspective manquante implique une transition de référence objective [(position endogène, perspective exogène): (position exogène, perspective exogène)]. De tels signaux de transition [Contenu: (Contenu: Contexte): Contexte] ordonnent l’évolution de la position de politique de gestion.

Le monde à l'envers : analyse de la structure du trafic transnational de drogues illicites

La thèse vise à analyser la structure des échanges transnationaux de cocaïne, d’héroïne et de marijuana. Partant de la perspective des systèmes-mondes, l’hypothèse que le trafic de drogues forme un système inverse au commerce légal est développée. Les outils de l’analyse de réseaux sont appliqués aux échanges de drogues entre pays. La thèse s’appuie sur deux sources de données complémentaires. La première est une banque d’informations uniques compilées par l’United Nations Office on Drugs and Crime (UNODC) sur les saisies d’importance effectuées dans le monde entre 1998 et 2007 (n = 47629). Ces données sont complétées par les informations contenues dans une dizaine de rapports publiés par des organismes internationaux de surveillance du trafic de drogues. Les réseaux d’échanges dirigés construits à partir de ces données permettent d’examiner l’étendue du trafic entre la plupart des pays du monde et de qualifier leur implication individuelle. Les chapitres 3 et 4 portent sur la structure du trafic elle-même. Dans un premier temps, les différents rôles joués par les pays et les caractéristiques des trois marchés de drogues sont comparés. Les quantités en circulation et les taux d’interception sont estimés pour les 16 régions géographiques définies par l’UNODC. Dans un deuxième temps, leurs caractéristiques structurelles sont comparées à celles des marchés légaux. Il en ressort que les marchés de drogues sont beaucoup moins denses et que les pays périphériques y jouent un rôle plus prononcé. L’inégalité des échanges caractérise les deux économies, mais leurs structures sont inversées. Le chapitre 5 propose une analyse de la principale source de risque pour les trafiquants, les saisies de drogues. Les données compilées permettent de démontrer que les saisies policières de drogues agrégées au niveau des pays sont principalement indicatrices du volume de trafic. L’éventuel biais lié aux pressions policières est négligeable pour les quantités saisies, mais plus prononcé pour le nombre de saisies. Les organismes de contrôle seraient donc plus à même de moduler leurs activités que les retombées éventuelles. Les résultats suggèrent aussi que les trafiquants adoptent des stratégies diverses pour limiter les pertes liées aux saisies. Le chapitre 6 s’attarde à l’impact de la structure sur le prix et la valeur des drogues. Le prix de gros varie considérablement d’un pays à l’autre et d’une drogue à l’autre. Ces variations s’expliquent par les contraintes auxquelles font face les trafiquants dans le cadre de leurs activités. D’une part, la valeur des drogues augmente plus rapidement lorsqu’elles sont destinées à des pays où les risques et les coûts d’importation sont élevés. D’autre part, la majoration des prix est plus prononcée lorsque les échanges sont dirigés vers des pays du cœur de l’économie légale. De nouveau, les rôles sont inversés : les pays généralement avantagés dépendent des plus désavantagés, et les pays pauvres en profitent pour exploiter les riches.

Analyse comparative de la pauvreté et de la structure de consommation des ménages dans la principale agglomération des Etats membres de l’UEMOA en 2008

L’objectif de cette étude est de réaliser une analyse comparative de la pauvreté et de la structure de consommation des ménages des capitales des Etats membres de l’Union Economique et Monétaire Ouest Africaine (UEMOA) à partir des données des enquêtes dépenses des ménages (EDM) réalisées en 2008 dans ces agglomérations. En s’appuyant sur l’approche monétaire de la pauvreté mise en oeuvre par la méthode du coût des besoins essentiels, il ressort que plus d’un ménage sur 10, soit 10,5% de l’ensemble de la population étudiée vit sous le seuil de pauvreté estimé à 277450 F CFA de dépenses annuelles par unité de consommation. Le test de dominance stochastique de 1er ordre confirme que l’ampleur du phénomène est en moyenne plus importante dans les villes sahéliennes (Bamako, Niamey, Ouagadougou) que dans les grandes villes côtières (Abidjan, Dakar, Lomé). Par ailleurs, l’analyse économétrique révèle que la taille du ménage et le capital humain du chef de ménage sont des déterminants importants du niveau de vie monétaire des ménages. En effet, tandis que le risque de pauvreté est plus élevé chez les ménages de grande taille, le niveau de vie d’un ménage est d’autant plus élevé que le niveau d’instruction du chef est important. En outre, on observe que dans les agglomérations où le taux de pauvreté est le plus élevé, les ménages accordent un poids plus élevé aux dépenses alimentaires. Enfin, l’estimation des élasticités dépenses totales de la demande à l’aide d’une régression linéaire suggère qu’en moyenne, les besoins de consommation insatisfaits par les ménages portent sur les services (les transports, la communication, la santé, l’éducation et les loisirs).

Economic Impact of Land Reforms in Kerala

The main aim of the present thesis is to dig deep into the once existed tenurial conditions and legislations that were passed to remedy the evils connected with the tenurial Conditions and to highlight ace of the economic impacts of the land reform legislation introduced since 1956.The thesis states that although the misery and exploitation which afflict the rural people and injustice inherent in the social structure can be removed by the strict implementation of land reforms. it is not the single and definite way or liberating the peasantry from its fate. Reform in not an Utopia: it is only the product of a constellation of political and social forces. ‘This study covers a period of twenty four years - ie...1956-1980.

A study of the cost structure of the cashew industry in kerala, karnataka and tamilnadu

Since the world demand for cashew kernels has been rising steadily for several years in the past, conferring significant price increase the processing of cashew remains a highly profitable lndustry. India being the earliest and largest supplier of cashew kernels in the world market it is our prestigious obligations to reestablish her pristine monopoly. Further the added importance ot the indutry in the Socio economic context of the State of Kerala makes various measures impervative in order to bring back to the industry its pristine glory at the late sixties to give a face lift and to stabilize the industry. This present study adopts a comprehensive frame work of analysis compassing the major issues involved in the cultivation, distribution, import, processing and marketing of cashew undcr the private and public sector, migration of the industry and the financial requirements of the industry.

Assessing the Precision of Compositional Data in a Stratified Double Stage Cluster Sample: Application to the Swiss Earnings Structure Survey

Precision of released figures is not only an important quality feature of official statistics, it is also essential for a good understanding of the data. In this paper we show a case study of how precision could be conveyed if the multivariate nature of data has to be taken into account. In the official release of the Swiss earnings structure survey, the total salary is broken down into several wage components. We follow Aitchison's approach for the analysis of compositional data, which is based on logratios of components. We first present diferent multivariate analyses of the compositional data whereby the wage components are broken down by economic activity classes. Then we propose a number of ways to assess precision

Intention-based economic theories of reciprocity

In recent years, several experiments have shown individuals exhibit authentic reciprocal behaviour in anonymous one-shot interactions. As reciprocity has been shown to be relevant in several economic fields, there have also been several attempts to model reciprocal bahaviour. I review the intention-based models of reciprocity and present an example of teacher management in the public sector in which the government offers an incentive scheme to implement a program. The incentive scheme has a prisoner´s dilemma structure. In both simultaneous and sequential games, equilibrium results may differ from those predicted by standard theory.
