خریداران عموماً در مورد کالاها براساس ویژگیهای بیرونی (extrinsic cues) آنها قضاوت می کنند ، به ویژه هنگامیکه سنجش ویژگیهای ذاتی کالا مشکل باشد. به همین علت است که کشـور سـازنده کـالـا، (country of origin or coo) ، یکی از این ویژگیهای بیرونی محصول ، عموماً برای ارزیابی کالاهای خارجی مورد استفاده قرار میگیرد. اثرات کشور سازنده کالا در حوزه رفتار خرید مصرف کننده (consumer buying behavior)بطور گسترده...
in order to prepare polyurethane elastomers with acceptable physical properties and good biocompatibility, novel polyurethane networks were synthesized via curing reaction of epoxy-terminated polyurethane prepolymers (eups) with hexamethylene diamine. eups were prepared from reaction of glycidol with nco-terminated polyurethanes (itps). itps were also synthesized from reaction of one equivalent...
Impulse buying behavior is a highly emotional activation, low cognitive control, and to a large extent a reaction that is critical to consumer behavior. This research examines the antecedents and implications of purchasing behavior through identification and ranking of the most important factors affecting impulse buying behavior.
