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

We examine voting by a board designed to mitigate conflicts of interest between privately informed insiders and owners. Our model demonstrates that, as argued by researchers and the business press, boards with a majority of trustworthy but uninformed “watchdogs” can implement institutionally preferred policies. Our laboratory experiments strongly support this conclusion. Our model also highlights the necessity of penalties on insiders when there is dissension among board members. However, penalties for dissent appeared to have little impact on the experimental outcomes.  相似文献

Social constructionist theories of gender are utilised to explore the relationship between household accounting and patriarchy during the early twentieth century in the USA and Britain. This period witnessed a reformulation of the ideology of domesticity founded on precepts derived from modish scientific management. It is argued that the suite of calculative techniques prescribed by ‘household engineers’ merely attempted to occupy middle class women in the domestic sphere. Rather than offering a source of professionalisation and liberation, the practice of financial management, costing, record keeping and time and motion study, contributed to a reassertion of private patriarchy, confirmed the gendered nature of spatiality, reinforced the role of woman as a consumer and diverted attention from career building outside the home.  相似文献

If one looks at environmental quality N as a renewable natural resource (with its own natural dynamics) which is changed by emissions Z, then one gets a better understanding of the shape of the damage function. In the case of a logistic growth dynamics one obtains a well-shaped transformation frontier N(Z), even in a two-species natural dynamics. For a more general natural interaction in the framework of a prey-predator model one obtains the possibilities of a cusp catastrophe which makes the transformation frontier N(Z) ill-shaped for the standard arguments of economists and their most favoured environmental policy instruments.  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

In 1995, the New South Wales Court of Appeal handed down a significant judgment on directors' duties in Daniels v Anderson1 (the AWA case), following the landmark decision of Rogers CJ (Comm. D.)2. In the same year, the Australian Stock Exchange introduced a listing rule under which listed Australian companies will for the first time be required to disclose their corporate governance practices. This article places the important decision in AWA and the ASX's corporate governance rule in the context of recent research in the United States on whether there is a link between corporate governance and corporate performance.  相似文献
