Applicatiion of Almost ideal demand system for a pharmaceutical

This thesis is an application of the Almost Ideal Demand System approach of Deaton and Muellbauer,1980, for a particular pharmaceutical, Citalopram, in which GORMAN´s (1971) multi-stage budgeting approach is applied basically since it is one of the most useful approach in estimating demand for differentiated products. Citalopram is an antidepressant drug that is used in the treatment of major depression. As for most other pharmaceuticals whose the patent has expired, there exist branded and generic versions of Citalopram. This paper is aimed to define its demand system with two stage models for the branded version and five generic versions, and to show whether generic versions are able to compete with the branded version. I calculated the own price elasticities, and it made me possible to compare and make a conclusion about the consumers’ choices over the brand and generic drugs. Even though the models need for being developed with some additional variables, estimation results of models and uncompensated price elasticities indicated that the branded version has still power in the market, and generics are able to compete with lower prices. One important point that has to be taken into consideration is that the Swedish pharmaceutical market faced a reform on October 1, 2002, that aims to make consumer better informed about the price and decrease the overall expenditures for pharmaceuticals. Since there were not significantly enough generic sales to take into calculation before the reform, my paper covers sales after the reform.

Värdefull litteratur : Fyra gymnasielärare om samhällsuppdragets etik i förhållande till litteraturen i klassrummet

The ethical aspects of the Swedish Curriculum for the non-compulsory school system, Lpf94, will form the basis of the research in this essay. The ethical aspects constitute fundamental values and goals as well as common tasks that must be carried out by every teacher. Since the school debate focuses a lot on this perspective, which is often mentioned together with the words problematic and contradictory, it will consequently also be the focus of this essay. Here these features are treated in relation to literature in all its forms used by teachers in class, which also represents a part of the school debate. Together ethics and literature form a perspective that lacks research. The goal is to investigate the ethical awareness of teachers in relation to the literature, and find out which ethical decisions are made by teachers and in what ways the ethical aspects of the curriculum is fulfilled. A qualitative method has been used in order to gain results: four upper secondary school teachers/senior high school teachers have been interviewed. The results are presented in interview transcripts which have been analyzed and interpreted in the light of recent studies and research and pedagogical-didactical literature. Accordingly I have been able to draw the conclusions that the ethical features in teaching is not explicit and that there seldom seems to be any conscious ethical reflections in relation to the literature. The ethical aspects are rather invisible and unconscious. However, it is clear that the interviews raise the awareness of the ethical perspective and thus emphasize the growing and developing function of the dialogue. Finally the results have been interpreted from the point of view of the ethical tasks of the teacher in order to make the ethics visible.I detta examensarbete ligger fokus på de etiska aspekterna av samhällsuppdraget i förhållande till den litteratur som lärare använder sig av i klassrumsundervisningen. Eftersom en stor del av skoldebatten handlar om samhällsuppdraget och dess värdegrund utgör också detta perspektiv utgångspunkten för denna undersökning. Målet är att undersöka vilka etiska avvägningar lärare gör i valet av litteratur och på vilket sätt samhällsuppdragets etik blir synlig i lärares arbete. Därmed framkommer också till viss del i vilken omfattning värdegrundsarbetet sker. Genom en kvalitativ undersökningsmetod i form av samtal har fyra gymnasielärare intervjuats. Erhållna resultat har presenterats i form av intervjutranskript som analyserats och tolkats med hjälp av aktuell forskning och pedagogisk-didaktisk litteratur. De slutsatser som kan dras utifrån resultaten är att etiken i lärarnas arbete inte är explicit och att det oftast inte finns en medveten etisk reflektion utifrån litteraturen. Etiken är snarare osynlig och tämligen omedveten. Dock medvetandegörs den under samtalen vilket framhåller dialogens betydelse för utveckling. Vidare framkommer att etiken aldrig är ett mål i sig, utan fungerar mer som medel för att nå andra mål i klassrummet. Slutligen, för att synliggöra etiken, har resultaten tolkats utifrån de etiska krav i samhällsuppdraget som ställs på lärare.
