An optimization model for volunteer assignments in humanitarian organizations

One of the challenges facing humanitarian organizations is that there exist limited decision technologies that are tailored specifically to their needs. While employee workforce management models have been the topic of extensive research over the past decades, very little work has yet concentrated on the problem of managing volunteers for humanitarian organizations. This paper develops a multi-criteria optimization model to assist in the assignment of volunteers to tasks, based upon a series of principles from the field of volunteer management. In particular, it offers a new volunteer management approach for incorporating the decision maker's preferences and knowledge into the volunteer assignment process, thus allowing him or her to closely examine the tradeoffs between potentially conflicting objectives. Test results illustrate the model's ability to capture these tradeoffs and represent the imprecision inherent in the work of humanitarian organizations, and thus demonstrate its ability to support efficient and effective volunteer management.     

TRANSATLANTIC CAPITAL MARKET PRICE DISCOVERY DURING A FINANCIAL CRISIS

Previous results show relatively small amounts of time variation in the Hasbrouck (1995) information share across international markets. Using data from a security that was cross‐listed on the New York and London Stock Exchanges in the 1860s, we find that the information share changes dramatically during a financial crisis that began in the foreign market.     

The Effects of Future Capital Investment and R&D Expenditures on Firms' Liquidity

The paper explores factors that lead to accumulation or decumulation of firms' cash reserves. In particular, the paper empirically examines whether additional future fixed capital and R&D investment expenditures induce firms to change their liquidity ratio while considering the role of market imperfections. Implementing a dynamic framework on a panel of US, UK, and German firms, it is found that firms in all three countries make larger adjustments to cash holdings when they plan additional future R&D rather than fixed capital investment expenditures. This behavior is particularly prevalent among financially constrained firms.     

An expectations-driven interpretation of the “Great Recession”

The boom-years preceding the “great recession” were a time of rapid innovation in the financial industry. We explore the idea that both the boom and eventual bust emerged from overoptimistic expectations of efficiency-gains in the financial sector. We treat the bankruptcy costs facing intermediaries in a costly state verification problem as a stochastic process, and model the boom-bust in terms of an unfulfilled news-shock where the expected fall in costs are eventually not realized. In response to a change in expectations only, the model generates a boom-bust cycle in aggregate activity, asset prices and leverage, and a countercyclical credit spread.     

Telecommunications technology applications and standards : A new role for the user

Telecommunications is at a critical juncture in the development of technology, policy and industry structure. The industry is becoming increasingly global and competitive; technology is developing faster than it can be implemented; and telecommunications is becoming strategically important to user organizations. Regulatory bodies and standards organizations are struggling with these developments. Public policy that encourages both competition in the telecommunications industry as well as the organized participation of users in the development of new technology applications, technical standards and industry regulations is essential for realizing the prospective benefits of the information age.     

New Product Development For Service Companies

It is well known that services differ from manufactured goods in a number of significant ways. Services are largely intangible, produced and consumed simultaneously, heterogeneous and perishable. These differences can lead to changes in service management. Christopher J. Easingwood has investigated how new products development practices in service organizations may reflect these differences. He has profiled practices found in a sample of service companies in the United Kingdom on topics ranging from idea generation to post-launch assessment, together with the strategic role and organizational location of new products. A number of special characteristics of the new product activity in services companies are identified. For instance, the number of new product introductions may be restricted due to customer and staff confusion when faced with a proliferation of service products. Test markets are used primarily to ensure the proper functioning of the service rather than to provide a base for a national sales projection. These and other characteristics appear to be appropriate adaptations to the special features of services. They are part of a pattern that shows some of the ways that service companies have adapted the new product development process to meet unique problems in the service environment.     

Managing radical innovation: an overview of emergent strategy issues

Despite differences in definitions, researchers understand that radical innovation within an organization is very different from incremental innovation , and and that it is critical to the long-term success of firms. Unfortunately, research has also shown that it is often difficult to get support for radical projects in large firms [14], where internal cultures and pressures often push efforts toward more low risk, immediate reward, incremental projects. Interestingly, we know considerably less about the effective management of the product development process in the radical than in an incremental context. The purpose of this study is to explore the process of radical new product development from a strategic perspective, and to outline key observations and challenges that managers face as they move these projects to market. The findings presented here represent the results of a longitudinal (since 1995), multidisciplinary study of radical innovation projects. A multiple case study design was used to explore the similarities and differences in management practices applied to twelve radical innovation projects in ten large, established North American firms. The findings are grouped into three high-level strategic themes. The first theme, market scope, discusses the challenges associated with the pursuit of familiar versus unfamiliar markets for radical innovation. The second theme of competency management identifies and discusses strategic challenges that emerge as firms stretch themselves into new and unfamiliar territory. The final theme relates to the people issues that emerge as both individuals and the project teams themselves try to move radical projects forward in organizations that are not necessarily designed to support such uncertainty.A breadth of subtopics emerge within and across this framework relating to such ideas as risk management, product cannibalization, team composition, and the search for a divisional home. Taken together, our observations reinforce the emerging literature that shows that project teams engaging in radical innovation encounter a much different set of challenges than those typically faced by NPD teams engaged in incremental innovation.     

The role of foreign currency debt in financial crises: 1880–1913 versus 1972–1997

We show that exposure to foreign currency debt does not necessarily increase the risk of having a financial crisis. Some countries do not suffer from financial fragility despite original sin. Before 1913 British offshoots and Scandinavia afflicted with it avoided financial meltdowns. Today many advanced countries have original sin, but few have had crises. In both periods, aggregate balance sheet mismatches are associated with a greater likelihood of a crisis. The evidence suggests that foreign currency debt is dangerous when mis-managed. This is part of the difference between developed countries and emerging markets both of which borrow in foreign currency.     

Integrated Market-Immersion Approach To Teaching New Product Development In Technologically-Oriented Teams

This article presents a market immersion methodology for teaching NPD in technologically-oriented teams. This methodology was developed during the early 1990s at the Lally School of Management and Technology of Rensselaer Polytechnic Institute. Since then, it has been successfully utilized to train in excess of one hundred MBA-level student teams. The NPD course is taught by a 5-member cross-functional team of faculty with backgrounds in marketing, manufacturing operations, and accounting. The course is modeled on Cooper's stage gate process, and the course is designed to provide a combination of classroom and apprenticeship experiences. The 6-credit, year-long course requires students to work in self-directed teams of approximately 5 to 6 members. Each student team chooses its own industry or technology domain in which to concentrate its efforts, and students undertake intensive market and field research in order to assess any existing market opportunities. Once a specific target market and market need have been identified, students are then required to design a product and an organization to meet that need. In specific, students must produce a detailed marketing, manufacturing, operations, advertising, distribution, and financial plan that can bring their product to market. During the process, students create multiple potential product designs, build mock-ups of their products, and field test the mock-ups. At every phase of the course, the teams are continuously immersed in real customer markets. As a result, teams must struggle to incorporate new market information and learning into their project in a consistent and holistic manner. The following article presents the curriculum content and tools, lessons learned, and student reactions to this original pedagogical approach to teaching NPD. Due to the length of the course, particular attention is paid to the teaming issues that naturally arise when teams work together on long-run projects. © 2002 Elsevier Science Inc.
