四步减少供应商风险

那些依靠供应商提供商品或服务的公司总是面临着由此而带来的财务风险.在经济环境艰难的时候,总有一些供应商要走向破产,在他们无力偿还债务的同时,金融机构又拒绝为他们提供每日运营所需的短期贷款.当企业走到快要山穷水尽的时候,他们会被迫不惜以降低产品质量和延长交付时间为代价来削减成本,而当企业这样做的时候,破产也就离他们不远了...     

2010：跨国企业高管下课之年

如果只是表现欠佳,许多董事会没有轻易地更换公司领袖。尽管各个产业的销售增长都十分疲软,在2010年的前9个月里,列入标准普尔500指数的公司当中还是只有34家任命了新的常任首席执行官。从高层更迭的速度来说,这已经是自2004年以来的最低水平了。正是在2004年,SpencerStuart猎头公司才开始跟踪这方面的数据。     

Cost-effectiveness of foreign aid programs in the baltics

After the upheavals in Central and Eastern Europe in the late 1980s and early 1990s, the Western world has given considerable aid to the fledgling democracies. In this paper we draw a summary from Baltic experience in the fields of educational programs, scientific and environmental programs, and commercial projects in banking, taxation, and energy. We analyze the motivation and identify different possible effects of foreign aid. We signal possible inefficiencies arising from the lack of coordination of foreign aid, deal with possible waste as being a form of loss in cost-effectiveness, and address the policies followed by aid-providing agencies. Finally, we suggest ways that can help to achieve cost-effectiveness by assisting the donor and recipient in maximizing benefits gained and possibly reducing costs.     

Suspending disbelief: Influencing engagement in scenarios of forest futures

Scenario analysis is an approach to long-term planning that informs decision-making in contexts of highly uncertain future conditions. Scenario-based studies are rapidly growing in popularity, yet many aspects of the method are not fully understood. Participants' willingness to suspend disbelief in possible futures is an integral component of scenario-based studies, essential for considering alternative future scenarios, yet little is known about the factors that affect it. Participation in a scenario project does not necessarily imply willingness or ability to suspend disbelief; participants may not suspend disbelief simply upon request. However, the scenario literature says little about the aspects of scenario-based studies that influence suspension of disbelief.This article explores the factors that influenced the suspension of disbelief in one scenario exercise about the future of Canada's forests. Participants differed in their abilities to suspend disbelief in the scenarios in part because of their past experiences and expertise in particular areas, and their assessments of probable and desired future outcomes. Elements of the project design and implementation influenced participants' abilities to engage the scenarios. The results have implications for those interested in using scenarios for helping people and communities envision possible - and sustainable - futures.     

Spousal Complementarity in Home Production

A bstract .   Economists have increasingly recognized the growing role of married women in the labor market by treating the labor supply decisions of married couples as joint decisions. However, they have yet to apply the same reasoning to home production. We build a more complete model of household time allocation that consists of a system of simultaneous equations estimating hours of labor supply and home production. Using data on white couples from Wave XXV of the Panel Study of Income Dynamics, we find that working wives act as if their husbands are substitutes for home production while other wives do not. Husbands' responses to their wives' behavior depends upon whether children are present.     

Asymptotics for Autocovariances and Integrated Periodograms for Linear Processes Observed at Lower Frequencies

One of the most frequently used class of processes in time series analysis is the one of linear processes. For many statistical quantities, among them sample autocovariances and sample autocorrelations, central limit theorems are available in the literature. We investigate classical linear processes under a nonstandard observation pattern; namely, we assume that we are only able to observe the linear process at a lower frequency. It is shown that such observation pattern destroys the linear structure of the observations and leads to substantially different asymptotic results for standard statistical quantities. Central limit theorems are given for sample autocovariances and sample autocorrelations as well as more general integrated periodograms and ratio statistics. Moreover, for specific autoregressive processes, the possibilities to estimate the parameters of the underlying autoregression from lower frequency observations are addressed. Finally, we suggest for autoregressions of order 2 a valid bootstrap procedure. A small simulation study demonstrates the performance of the bootstrap proposal for finite sample size.
