Public Policy and Diet Quality: Impact of Prices on Nutrient Adequacy using French Expenditure Data from 1996 to 2005

This paper aims at simulating optimal prices satisfying public health recommendations in terms of nutrient adequacy. This implies to estimate a complete food demand system in order to compute price elasticities. Food consumption behaviors are described by an AI functional form [Deaton and Muellbauer(1980)] augmented to control for habit persistence. The demand system is estimated using the Iterated Least Square Estimator developed by Blundell and Robin (1999). We use French household expenditure data drawn from TNS Worldpanel covering 130 periods of 4 weeks from 1996 to 2005. Given the nature of our data, households are split into 8 cohorts based on two socio-demographic variables: date of birth and social status. A revised aggregation into 27 food groups is proposed in this paper. More precisely, commodities are grouped into homogeneous categories in terms of nutritional content and consumer preferences. Nutrient adequacy is defined using the MAR (Mean Adequacy Ratio), a nutrient only-based indicator. We calculate nutrient adequacy for 12 essential nutrients. Optimal prices are derived following Ramsey's approach to optimal taxation; Maximizing social welfare under nutritional constraints results in 27 optimal price variations or tax rates, each defined as a nonlinear function of all direct and cross price elasticities and the above mentioned indicator for all food groups.Household survey data, cohort, AI demand system, nutrient adequacy, diet quality, fat tax policy, Consumer/Household Economics, Food Consumption/Nutrition/Food Safety, Health Economics and Policy, D12, C33,

Collections as Data: Implications for Enclosure

In recent years a growing amount of interest has been dedicated to collections as data. A collections as data paradigm seeks to foster an expanded set of research, pedagogical, and artistic potential predicated on the computational use of cultural heritage collections. Collections as data raises the question of what it might mean to treat digitized and born digital collections as data rather than simple surrogates of physical objects or static representations of digital experience

Analytical Framework for the Use of Information and Communication Technologies. Diagnosis in Government and Civil Society Organizations in Mexico

Este artículo tiene como objetivo proponer un marco analítico para el aprovechamiento de las TIC en organizaciones gubernamentales y de la sociedad civil con fines sociales, el cual se integró a través de estudios y encuestas previas. Este marco sirvió de base para el análisis de los datos derivados de una encuesta en línea aplicada a 203 organizaciones mexicanas centradas en el desarrollo de los jóvenes. Los hallazgos muestran el nivel de aprovechamiento de las TIC con relación a tres niveles de uso (básico, intermedio y alto) y 11 dimensiones. Se encuentra que los usos de las TIC se aprovechan principalmente con fines administrativos y de difusión y en menor medida para potenciar sus capacidades para responder a las problemáticas sociales que atienden. El estudio genera conocimiento sobre organizaciones que son agentes claves para el desarrollo y el cambio social y es una propuesta replicable para otras organizaciones y contextos.The objective of this paper is to propose an analytical framework for the use of ICT in governmental and civil society organizations for social development, which was integrated through the review of previous studies and surveys. Data from an online survey applied to 203 mexican organizations focused on the development of young people were analyzed based on this framework. The findings show the level of use of ICT in relation to three levels of use (basic, intermediate and high) and 11 dimensions. It is found that the use of ICTs is mainly for administrative and dissemination purposes and to a lesser extent to enhance their capacities to respond to the social problems they address. This study generates knowledge about these organizations which are key actors for development and social change. Addtionally, this proposal is replicable in other organizations and contexts
