Our audit study of retail stores in Vienna documents previously unknown and important facts. Stores agree to a discount off of the posted price approximately 40% of the time. Discounts are more likely to be granted by small-scale firms, for higher-priced products, and for non-sale items. Our findings are consistent with the predictions of a principle-agent model in which a firm decides whether to augment posted prices with bargaining concessions.application/pdfengL'accés als continguts d'aquest document queda condicionat a l'acceptació de les condicions d'ús establertes per la següent llicència Creative Commons
