Deux approches de l'influence du discours économique sur les phénomènes sociaux

The influence of theoretical discourse on the corresponding field of investigation is an important feature of social science : social scientists shape the world by describing it. This phenomenon has been studied in several ways. Economic sociology has recently focused on the fact that the economy is embedded in the economics through which it is scrutinized. Great names of economic theory have focused on the effects of economists' discourse on agents' behaviours. This article aims to bring out the distinction between these two kinds of contributions which deal with the same object. Finally, it explains the analytical distinction by a difference in the initial problematic. Following trends in the French school of the economics of convention, the social influence of theoretical discourse is analyzed on the strategic side (in connection with economics) and on the interpretative side (in connection with sociology).

Regional consumption of antibiotics : a demand system approach

Through this paper. we have attempted to model the demand for different 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 effects of antibiotic use in terms of bacterial resistance. Elasticities to socioeconomic determinants of consumption and own- and cross-price elasticities between different groups of antibiotic have also been computed in this paper. Significant cross-price elasticities are found between newer or more expensive generations and older or less expensive generations of antibiotics. (C) 2009 Elsevier B.V. All rights reserved.
