Regional consumption of antibiotics: a demand system approach
نویسندگان
چکیده
Through this paper, we have attempted to model the demand for di¤erent classes of antibiotics used for respiratory infections in outpatient care in Switzerland using a spatial version of the linear approximate Almost Ideal Demand System (AIDS) model. This model takes spatial dependency into account by means of spatial lags of antibiotic budget shares. We control for the health status of patients and the potential harmful e¤ects of antibiotic use in terms of bacterial resistance. Elasticities to socioeconomic determinants of consumption and ownand cross-price elasticities between di¤erent groups of antibiotic have salso been computed in this paper. Signi cant cross-price elasticities are found between newer or more expensive generations and older or less expensive generations of antibiotics. JEL classi cation: I0; C3; C43
