Determinación e interpretación de la calidad del agua y del suelo en el Distrito de Riego 066 Del Valle de Santo Domingo, Baja California Sur. Colegio de Postgraduados
Marín Celestino, Ana Elizabeth.
La calidad del agua y del suelo en un área agrícola son factores principales que repercuten en su sustentabilidad, debido a que una baja calidad en estos recursos reduce los rendimientos y causa toxicidad en los cultivos entre otros efectos adversos, afectando la productividad de la actividad y al ambiente. En el Distrito de Riego 066 del Valle de Santo Domingo se han detectado alteraciones notables en estos recursos, por esta razón este estudio planteó como objetivo evaluar e interpretar la calidad del agua del acuífero y suelo en el DR 066 y su relación con la producción agrícola. Se colectaron muestras de agua en 600 pozos de riego y de suelo en 710 parcelas; en cada muestra se determinó los siguientes parámetros: pH, CE, RAS, cationes, aniones, metales...

FIRMS’ RESPONSES TO NUTRITIONAL POLICIES AgEcon
Duvaleix-Treguer, Sabine; Hammoudi, Hakim; Rouached, Lamia; Soler, Louis-Georges.
The aim of this paper is to examine the effects of nutritional policies on the behavior of firms, particularly in terms of food quality and prices, and to assess the potential impacts of such policies from a public health point of view. We determine how new products that are nutritionally improved can emerge in a market where incumbent firms offer competing unhealthy products. We also highlight a non-intentional effect of such policies: if consumer heterogeneity is high, then an information policy may simultaneously provide health benefits to the population as a whole but worsen the health of consumers that are less aware of nutritional effects. For a given level of nutritional tax, we determine the optimal threshold that firms must meet to avoid taxation....

The International Quality Systems Environment AgEcon
Krieger, Stephanie; Schiefer, Gerhard.
Enterprises in the agri-food sector are increasingly confronted with the need to adjust their production processes and operations to the requirements of quality systems and to integrate these requirements into their own individual integrated process management system. Integra- tion efforts are further aggravated by correlations of quality system requirements with other process related requirements. First initiatives have started to benchmark the requirements of different quality systems to have an analyse about the level of the same requirements. Output of this article will be a description of an advisory model (database model with computerized support), which presents a support tool for the implementation of quality, environ- mental and occupational...

Individual and Collective Reputation: Lessons from the Wine Market AgEcon
Castriota, Stefano; Delmastro, Marco.
The concept of reputation has been used in every field of economic research, given its capacity to affect the outcome of all economic and financial transactions. The theoretical debate on reputation is very rich, but the mechanisms of reputation building have not been explored enough from the empirical viewpoint. In this paper we investigate the determinants of firm reputation taking into consideration the interactions between individual and collective reputation. This paper is one of the first attempts to provide robust evidence on the determinants of firm reputation using a large set of controls applied to a database not affected by self-selection bias. In fact, we constructed a new database containing the universe of wineries located in four regions of...

The Rapid Rise of Supermarkets in Developing Countries: Induced Organizational, Institutional, and Technological Change in Agrifood Systems AgEcon
Reardon, Thomas; Timmer, C. Peter; Berdegue, Julio A..
There has been extremely rapid transformation of the food retail sector in developing regions in the past 5 to 10 years, accompanied by a further consolidation and multi-nationalization of the supermarket sector itself. This organizational change, accompanied by intense competition, has driven changes in the organization of procurement systems of supermarket chains, toward centralized and regionalized systems, use of specialized/dedicated wholesalers and preferred supplier systems, and demanding, private quality standards. These changes in the system have in turn determined the very recent rise of the use of contracts between supermarkets and agrifood producers in these regions to cover provision of services and provision for risk management, as well as...

Do Consumers Trust the National Inspection Exemption Brands? Evidence from Infant Formula in China AgEcon
Jin, Yanhong H.; Lin, Liguo; Yao, Lan.
Consumers are often uncertain about product quality and have to rely on different information, either given or pursued, to assess quality. Developing countries may lack institutional and technical resources to rigorously monitor and enforce product quality standards and/or to implement market-based instruments where market failures are common. The information-based instruments on product quality may work well in these countries as they reduce information asymmetry between firms and consumers. This study investigates one particular information-based instrument, the National Inspection Exemption (NIE) system in China. China launched the National Inspection Exemption (NIE) System in various industries in 2000 to award firms who are in compliance with the...
