n-player coalitional games with transferable payo® o®er a promising framework for analyzing value appropriation under competition. But making progress necessitates understanding how the force of a player's value-producing alternatives a®ects the upper and lower bounds of his set of equilibrium (core) payo®s. Unfortunately, there are virtually no results of this kind. We explore the determinants...

We present the solution that Hypo Real Estate Bank International (Hypo) implemented to perform Monte Carlo simulations of its commercial real estate credit risk. The solution uses Risk Integrated’s proprietary software, the Specialized Finance System, which is supported by another Risk Integrated technology, the Enterprise Spreadsheet Platform. The platform embeds individual master spreadsheets...

The paper proposes a solution for the Grid scheduling problem, addressing in particular the requirement of high performance an efficient algorithm must fulfill. Advance Reservation engages a distributed, dynamic, fault-tolerant and efficient strategy which reserves resources for future task execution. The paper presents the main features of the strategy, the functioning mechanism the strategy i...

Discrimination as a Competitive Device: The Case of Local Television News Local news offers a unique look not only at customer preferences but also at the strategic response of firms to these preferences. This paper uses a combination of ratings data and newly gathered information on television stations in 25 U.S. markets to examine the decisions of competing firms and how customers respond to ...

HE retirement is a concept of recent origin though it could be traced to Indian philosophy. The reasons related to voluntary retirement scheme (VRS) of Government of India and its response by public sector employees have been analyzed in this paper. There are number of reasons for opting to VRS like doing some business, job dissatisfaction, health and personal reasons. There exists variation in...

In this paper, we consider the problem of resource reservation for networks. Current approaches for resource reservation in Integrated Service Networks adopt an all-or-nothing approach, where partially acquired resources must be released if resources are not available at all routers on the chosen path. Furthermore, under high load, endsystems must retry requests repeatedly leading to inefficien...

Peer-to-peer file-sharing systems have poor search performance for rare or poorly described files. These files lack a quality or variety of metadata making them hard to match with queries. A server can alleviate this problem by gathering the descriptors used by peers via what we call probe queries, and use these descriptors to improve its own. We consider probe query triggering mechanisms and c...

The continuous technological development and the consistent reliance on ICT, has raised the expectations towards ubiquitous connectivity to an extent that technical failures or social disconnects are a serious threat for project teams and their performance, especially when team members are scattered around the world. We analyse hypo-connectivity, the state in which users face too few connectivi...

Reasons behind the failure and success of large-scale information systems projects continue to intrigue researchers. In particular in the airline industry very successful (passenger reservation) systems have been built which have totally changed the competitive arena of the industry. On the cargo side however attempts to implement large-scale community systems have largely failed across the glo...

The 1906 Colombia–Ecuador earthquake induced both strong seismic motions and a tsunami, the most destruc‐ tive earthquake in the history of the Colombia–Ecuador subduction zone. The tsunami propagated across the Pacific Ocean, and its waveforms were observed at tide gauge stations in countries including Panama, Japan, and the USA. This study conducted slip inverse analysis for the 1906 earthqua...
