Changes in the relative share of different age groups in the population may present inflationary, disinflationary, or even deflationary tendencies. We find evidence that increases in the share of the very old (age 80 and older) may be associated with deflation. The analysis is based on an international dataset over a long period. Classifying age groups into young, working, younger old, and older old, we find that the shares of the young and the younger old groups are inflationary, while those of the working group are disinflationary and those of the very old group seemingly deflationary. 相似文献

This is the report of a study which has sought to take steps towards increasing both our knowledge of how consumers assess the service product offered by conference hotels, and, at the same time, our understanding of the dimensions of service quality and how they may be measured. The authors seek to show how their approach to measuring service quality was developed and refined. Some preliminary findings of the final stage of the study are presented, which identify the key elements that go to make up the perceived quality of the conference hotel service product, utilising the notion of ‘net service quality’. 相似文献
