The paper asks the question – as time series analysis moves from consideration of conditional mean values and variances to unconditional distributions, do some of the familiar concepts devised for the first two moments continue to be helpful in the more general area? Most seem to generalize fairly easy, such as the concepts of breaks, seasonality, trends and regime switching. Forecasting is more difficult, as forecasts become distributions, as do forecast errors. Persistence can be defined and also common factors by using the idea of a copula. Aggregation is more difficult but causality and controllability can be defined. The study of the time series of quantiles becomes more relevant.  相似文献

Two of the main forces driving European emigration in the late nineteenth century were real wage gaps between sending and receiving regions and demographic booms in the low‐wage sending regions. Our new estimates of net migration for the countries of sub‐Saharan Africa show that exactly the same forces driving African across‐border migration are at work today. The results suggest that rapid growth in the cohort of potential young emigrants, population pressure on the resource base, and slow economic growth are likely to intensify the pressure for migration out of Africa and into high‐wage OECD countries over the next two decades.  相似文献

This study investigates the presentations of Hiroshima and Nagasaki as postwar tourism destinations in a selection of Japanese-language guidebooks. Comparison is made between commonly voiced criticisms of Japanese attitudes toward the two atom-bombed sites and the tourism activities suggested by the publications themselves. An expected presentation emphasizing Japanese suffering as a result of the atom bombs is not found in the guides, but neither is an openness to discussion of the war. The conclusions reached find Hiroshima standing as emblematic of the rebuilding nation as a whole, while Nagasaki remains largely outside of the social and cultural dynamics of postwar Japan.  相似文献

Outsourcing is becoming a major option in British business, including the financial services industry, and it raises a number of ethical considerations. The author of this major ethical study contends that "Outsourcing seems to present a particular threat to employees ... because of the factors which have led to outsourcing and the way in which it tends to work." Mike Henderson is an Associate of the Chartered Institute of Bankers and Senior Lecturer in Financial Services in the School of Financial Studies and Law of Sheffield Hallam University, City Campus, Pond Street, Sheffield S1 1WB, England.  相似文献

A growing awareness of workplace hazards and identification of airborne contaminants, coupled with a changing safety and health regulatory environment, created an unexpected demand for new and innovative respirators in the early 1980s. 3M's Occupational Health and Environmental Safety Division broke new ground by taking the team concept further than ever before in the company. The division's Action Teams successfully designed, built and introduced products in less than half the time it would have taken previously. Robert Hershock, Charles Cowman and Douglas Peters describe how 3M learned important lessons about team selection, training, performance and motivation, the importance of project sponsors, and the role of middle management.  相似文献
