    A SIMPLE MODEL OF VOLUNTARY VS MANDATORY LABELLING OF GMOS

    Get PDF
    We consider the welfare impact of the mandatory and voluntary labelling to inform consumers on GMOs content in foods. With a model of vertical differentiation in competitive markets, we evaluate the effects on price equilibrium and welfare levels. We find that the mandatory labelling scheme would be optimal in those countries with more GMO-averse consumers and no-GMOs practices producers. Voluntary labelling would instead optimally be chosen in those countries where producers are using GMOs and consumers are more concerned about the costs savings resulting in this technology adoption.Research and Development/Tech Change/Emerging Technologies,

    Environmental and food safety standards in the context of trade liberalization: Issues and options

    Full text link
    The current debate on trade liberalization is accompanied by an increased concern about environmental and food safety issues leading to frictions of different country groups under the World Trade Organization (WTO). This discussion paper aims at shedding more light on some of the issues in the trade and environment debate. It describes the complex process of setting standards, the relevant WTO agreements dealing with technical as well as sanitary and phytosanitary standards and potential outcomes of setting environmental standards-outcomes for the environment, for international trade relations and the competitiveness of countries. The theoretical part shows that under certain assumptions, not only protectionist but also environmental concerns may lead to a political decision for suboptimal standards. Finally, the paper offers a list of alternative policy responses and strategies to tackle environmental issues in the context of international trade. This includes the polluter-pays principle, eco-labeling and other labeling schemes, reducing in- and output subsidies, stronger enforcement of given standards, technical assistance, harmonization and mutual recognition of equivalent standards, and multilateral environmental agreements (MEAs). It is concluded that while no individual strategy proves to be the optimal solution, a mixture of different approaches is needed and care has to be taken to avoid the misuse of environmental standards for protectionist reasons. The participation of developing countries should be increased when setting standards at international level, defining criteria for eco-labels or negotiating MEAs

    Displacement due to violence in Columbia: Determinants and consequences at the household level

    Full text link
    The armed conflict over economic and political power in Colombia has led to the massive displacement of people living in the areas of violence. The design of appropriate policies of prevention, assistance, and resettlement requires improved information on the determinants and effects of displacement. This paper contributes to providing such information by using household survey data collected at expulsory and receptor locations. First, we develop a conceptual framework for analyzing the factors which influence a household's decision to leave its area of origin for an uncertain future or to stay and risk being the victim of violence. Using econometric analysis, the framework is then used to examine the significance and relative importance of the hypothesized factors in the study region. Second, the impacts of displacement on the affected households are examined through a descriptive analysis of the survey data, and a method for estimating the welfare losses of the displaced is presented. The results confirm the significant role of violence and perceptions of insecurity in motivating displacement. The analysis indicates that land owners, members of local organizations, and younger household heads face the highest risk of becoming the direct target of threats which appear to be the most important trigger of displacement. However, security considerations do not appear to be the only factors underlying the displacement decision. People decide to stay in their areas of origin despite being affected by violence. A significant percentage of the displaced appear to have reflected on their options and on the expected impacts of displacement. Considerations regarding the cost of leaving behind important assets and potential improvements in living conditions after displacement appear to impact the decision. The results also point to the important role of information in displacement decisions. The descriptive analysis highlights the impacts of displacement on the affected households. The wide majority of the displaced had lived in the areas of origin for a very substantial amount of time. For many, displacement implies the loss of agricultural land and the associated way of life. At the receptor locations, households - particularly those from rural areas - have to look for types of employment they are not trained for. A very substantial proportion ends up being long-term unemployed. The surveys point to the need for programs which provide long-term opportunities to the displaced. The paper concludes with policy recommendations and topics for future research

    A simple model of voluntary vs mandatory labeling of GMOs

    We consider the welfare impact of the mandatory and voluntary labeling policies to inform consumers on GMOs content in foods. With a model of vertical di\ua4erentiation in competitive markets, we evaluate the e\ua4ects on price equilibrium and welfare levels. The model provides a potential explanation of observed di\ua4erences in preferences across countries and a\ua4ected groups. We ...nd that the mandatory labeling scheme would be optimal in those countries with more GMO-averse consumers and GMO-free produc- ers. Voluntary labeling would instead optimally be chosen in those countries where producers are using GMOs and consumers are more concerned about the cost savings resulting in this technology adoption. We derive the socially-optimal scheme and show how it depends on the parameters of the problem, notably consumer preferences and costs of the di\ua4erent schemes

    Analysis of death in major trauma: value of prompt post mortem computed tomography (pmCT) in comparison to office hour autopsy

    Background: To analyze diagnostic accuracy of prompt post mortem Computed Tomography (pmCT) in determining causes of death in patients who died during trauma room management and to compare the results to gold standard autopsy during office hours. Methods: Multiple injured patients who died during trauma room care were enrolled. PmCT was performed immediately followed by autopsy during office hours. PmCT and autopsy were analyzed primarily regarding pmCT ability to find causes of death and secondarily to define exact causes of death including accurate anatomic localizations. For the secondary analysis data was divided in group-I with equal results of pmCT and autopsy, group-II with autopsy providing superior results and group-III with pmCT providing superior information contributing to but not majorly causing death. Results: Seventeen multiple trauma patients were enrolled. Since multiple trauma patients were enrolled more injuries than patients are provided. Eight patients sustained deadly head injuries (47.1 %), 11 chest (64.7 %), 4 skeletal system (23.5 %) injuries and one patient drowned (5.8 %). Primary analysis revealed in 16/17 patients (94.1 %) causes of death in accordance with autopsy. Secondary analysis revealed in 9/17 cases (group-I) good agreement of autopsy and pmCT. In seven cases autopsy provided superior results (group-II) whereas in 1 case pmCT found more information (group-III). Discussion: The presented work studied the diagnostic value of pmCT in defining causes of death in comparison to standard autopsy. Primary analysis revealed that in 94.1% of cases pmCT was able to define causes of death even if only indirect signs were present. Secondary analysis showed that pmCT and autopsy showed equal results regarding causes of death in 52.9%. Conclusions: PmCT is useful in traumatic death allowing for an immediate identification of causes of death and providing detailed information on bony lesions, brain injuries and gas formations. It is advisable to conduct pmCT especially in cases without consent to autopsy to gain information about possible causes of death and to rule out possible clinical errors

    Helden in der Schule. Akten der Tagung Kloster Banz 2014

    Ausgehend von der Feststellung, dass die Integration mittelalterlicher Texte im Deutschunterricht in der Schulpraxis weitgehend ein Desiderat darstellt, präsentierten Beitragende aus Schule und Wissenschaft bei der Tagung „Helden in der Schule“ im Oktober 2014 ihre Projekte und Ideen zu und Erfahrungen mit der Implementation germanistisch-mediävistischer Inhalte im Deutschunterricht. Dabei reichen die Beiträge von allgemeinen Überlegungen zum Nutzen mittelalterlicher Literatur in der Schule über konkrete Unterrichtsentwürfe bis hin zur Umsetzung in der Waldorfschule und der Integration schulbezogener Lehrveranstaltungen in der Universität. Bei aller Verschiedenheit in den Herangehensweisen wird in allen Beiträgen eindrucksvoll deutlich gemacht, dass mittelalterliche Literatur auch im 21. Jahrhundert überaus lohnend in die Unterrichtspraxis einbezogen werden kann.Since medieval texts are not treated enough in school, lecturers working in school and university presented their projects, ideas and experiences concerning the implementation of German-mediavistic contents in German school lessons during the conference “Heroes in School” in October 2014. The topics concern general reflection about the profitability of medieval literature in school, concrete lesson plans, the implementation in Rudolf Steiner schools, the integration of seminars in university that deal with the work in school etc. All articles demonstrate that the integration of medieval literature in school worth the effort – also in the 21st century

    No association between the common calcium-sensing receptor polymorphism rs1801725 and irritable bowel syndrome

    Get PDF
    Background The calcium-sensing receptor (CaSR) is a calcium (Ca2+) sensitive G protein-coupled receptor implicated in various biological processes. In particular, it regulates Ca2+/Mg2+- homeostasis and senses interstitial Ca2+ levels and thereby controls downstream signalling cascades. Due to its expression in the gut epithelium, the enteric nervous system and smooth muscles and its key function in regulation and coordination of muscular contraction and secretion, it represents an excellent candidate gene to be investigated in the pathophysiology of irritable bowel syndrome (IBS). Disturbed CaSR structure and function may impact gastrointestinal regulation of muscular contraction, neuronal excitation and secretion and consequently contribute to symptoms seen in IBS, such as disordered defecation as well as disturbed gut motility and visceral sensitivity. Methods We have therefore genotyped the functional CASR SNP rs1801725 in three case control samples from the UK, Belgium and the USA. Results Genotype frequencies showed no association in the three genotyped case–control samples, neither with IBS nor with IBS subtypes. Conclusions Although we could not associate the SNP to any of the established bowel symptom based IBS subtypes we cannot rule out association to altered Ca2+ levels and disturbed secretion and gut motility which were unfortunately not assessed in the patients genotyped. This underlines the necessity of a more detailed phenotyping of IBS patients and control individuals in future studies
