Using proxies for the short rate: when are three months like an instant?

The dynamics of the unobservable short rate are frequently estimateddirectly using a proxy. We examine the biases resulting fromthis practice (the 'proxy problem'). Analytic results show thatthe proxy problem is not economically significant for single-factoraffine models. In the two-factor affine model of Longstaff andSchwartz (1992), the proxy problem is only economically significantfor pricing discount bonds with maturities of more than fiveyears. We also describe two different numerical procedures forassessing the magnitude of the proxy problem in a general interestrate model. When applied to a nonlinear single-factor model,they suggest that the proxy problem can be economically significant.     

Diversity in organizations: Where are we now and where are we going?

A great deal of research has focused on workforce diversity. Despite an increasing number of studies, few consistent conclusions have yet to be reached about the antecedents and outcomes of diversity. Likewise, research on different dimensions of diversity (e.g., age, race, gender, sexual orientation, disability, and culture) has mostly evolved independently. Therefore, the purpose of this review is to examine each of these dimensions of diversity to describe common themes across dimensions and to develop an integrative model of diversity.     

The future of the uplands

Upland areas provide UK society with many important functions, goods and services, but have experienced a number of disturbing trends and face an uncertain future. This paper outlines historic, current and future drivers of environmental, economic, socio-cultural and policy change in UK uplands, and assesses how these have affected or are likely to affect ways in which land is used and the provision of ecosystem services. Information is synthesised into scenarios summarising a range of possible futures anticipated for UK uplands to 2060 and beyond. Finally, innovations in science, technology, governance and policy are evaluated that could enable uplands to continue providing key ecosystem services under a range of scenarios. The paper concludes that many upland areas will need to be prepared for significant reductions in grazing and prescribed burning. Conversely, other areas could experience agricultural intensification, for example significant increases in grazing or an expansion of arable or bioenergy crops into upland valleys, due to anticipated increases in global demand for food and energy. These scenarios will take place in the context of climate change. Many may take place together and may interact with each other, with complex and unpredictable implications for the upland environment, economy and society. In this context, a number of advances are needed in science, technology and policy to maintain viable upland communities and the future provision of ecosystem services. These may include funding for ecological and hydrological restoration via carbon offsetting or other means. It may also involve advances in ecosystem service modelling, mapping and valuation, which through stakeholder participation could facilitate more integrated rural planning. New forms of environmental governance need to be explored that can empower those interested in developing upland economies to maintain thriving upland communities, while managing the ecosystem services they provide as efficiently as possible.     

Disaster relief routing: Integrating research and practice

Disaster relief presents many unique logistics challenges, with problems including damaged transportation infrastructure, limited communication, and coordination of multiple agents. Central to disaster relief logistics is the distribution of life-saving commodities to beneficiaries. Operations research models have potential to help relief agencies save lives and money, maintain standards of humanitarianism and fairness and maximize the use of limited resources amid post-disaster chaos. Through interviews with aid organizations, reviews of their publications, and a literature review of operations research models in transportation of relief goods, this paper provides an analysis of the use of such models from the perspective of both practitioners and academics. With the complexity of disaster relief distribution and the relatively small number of journal articles written on it, this is an area with potential for helping relief organizations and for tremendous growth in operations research.     

Corporate Ethical Values and Altruism: The Mediating Role of Career Satisfaction

This study explores the ability of career satisfaction to mediate the relationship between corporate ethical values and altruism. Using a sample of individuals employed in a four-campus, regional health science center, it was determined that individual career satisfaction fully mediated the positive relationship between perceptions of corporate ethical values and self-reported altruism. The findings imply that companies dedicating attention to positive corporate ethical values can enhance employee attitudes and altruistic behaviors, especially when individuals experience a high degree of career satisfaction.     

Financing municipal BOOTs in South Africa: The lenders' perspective

South Africa's first build‐own‐operate‐transfer (BOOT) project for municipal services was signed in late December 1998 by the city of Durban and a private project company associated with French conglomerate Vivendi. The project will treat waste water for sale to industrial customers who would otherwise use more expensive potable water in their manufacturing processes. The project structure, with its multiple contracts and supporting agreements, guarantees and complex shareholding relationships, represents a sophisticated analytical challenge for lenders, whose financing will ultimately be at risk in the deal. Development finance institutions, such as the Development Bank of Southern Africa (DBSA), must review such projects in even greater detail because of their mandate to promote sustainable infrastructure development in the region. This article presents the DBSA ‘s analytical perspective on the Durban BOOT project in an effort to capture the complex, innovative and strongly developmental character of what, for South Africa, is a ground‐breaking public‐private partnership project.     

Strategic individual assessment: Issues in providing reliable descriptions

Individual assessment involves one psychologist making an assessment of an individual for personnel-related purposes. Individual assessment practice is reviewed, and research on reliability is presented. A study examining the comparability of conclusions reached by consumers is presented. Eighty-six students and thirty-eight managers read nine narrative assessment reports (three of each of three job candidates) and attempted to determine which reports described the same candidate. None of the subjects could correctly group the nine reports; a sizeable proportion did no better than chance in grouping the reports. Implications for assessors and consumers of individual assessments are discussed.     

Do borrowers know their mortgage terms?

We assess whether borrowers know their mortgage terms by comparing the distributions of these variables in the household-reported Survey of Consumer Finances (SCF) to the distributions in lender-reported data. We also examine the characteristics of SCF respondents who report not knowing these contract terms. Although most borrowers seem to know basic mortgage terms, borrowers with adjustable-rate mortgages appear likely to underestimate or to not know how much their interest rates could change. Borrowers who could experience large payment changes if interest rates rose are more likely to report not knowing these contract terms. Difficulties with gathering and processing information appear to be a factor in borrowers' lack of knowledge.
