This paper develops a general framework for analyzing corporate risk management policies. We begin by observing that if external sources of finance are more costly to corporations than internally generated funds, there will typically be a benefit to hedging: hedging adds value to the extent

functions is also common to organizations like large professional partnerships, financial mutuals and nonprofits. We contend that separation of decision and risk bearing functions survives in these organizations in part because of the benefits of specialization of management and risk bearing but also

In this paper I derive a risk-adjusted measure of portfolio performance (now known as "Jensen's Alpha") that estimates how much a manager's forecasting ability contributes to the fund's returns. The measure is based on the theory of the pricing of capital assets by Sharpe

costs. ALTHOUGH MUCH ACADEMIC RESEARCH on mutual funds addresses issues of performance measurement and attribution, we can learn more from this industry than whether fund managers can consistently earn risk-adjusted excess returns. Researchers studying funds have shed light on how incentives affect fund

and computational risk management to sustain Service Level Agreement (SLA)-oriented resource allocation. In addition, we reveal our early thoughts on interconnecting Clouds for dynamically creating global Cloud exchanges and markets. Then, we present some representative Cloud platforms, especially those developed

or functionality for speed. Few offer resource isolation or performance guarantees; most provide only best-effort provisioning, risking denial of service. This paper presents Xen, an x86 virtual machine monitor which allows multiple commodity operating systems to share conventional hardware in a safe and resource

Abstract In an intensifying international competition banks are forced to place increased emphasis on enterprise wide risk-/return management. Financial risks have to be limited and managed from a bank wide portfolio perspective. Risk management requirements have to be met from an internal as well

budget with minimal risk of exceeding it. We use our modeling framework to estimate the potential of power management schemes to reduce peak power and energy usage. We find that the opportunities for power and energy savings are significant, but greater at the cluster-level (thousands of servers) than

of interest is how almost blind animals manage to establish shortest route paths from their colony to feeding sources and back. In the case of ants, the media used to communicate among individuals information regarding paths and used to decide where to go consists of pheromone trails. A moving ant lays some
