This article introduces volume leases as a mechanism for providing server-driven cache consistency for large-scale, geographically distributed networks. Volume leases retain the good performance, fault tolerance, and server scalability of the semantically weaker client-driven protocols that are now used on the web. Volume leases are a variation of object leases, which were originally designed f...

Dynamic Host Configuration Protocol (DHCP) is designed to provide an automatic mechanism for the allocation, configuration and management of IP addresses and TCP/IP protocol stack parameters of computers and devices in IP networks. The important feature of DHCP is a “dynamic allocation” mechanism, which assigns an IP address to a client for a limited period of time (called a lease time). Theref...

Cloud computing is driven by economies of scale. A cloud system uses virtualization technology to provide cloud resources (e.g. CPU, memory) to users in form of virtual machines. Virtual machine (VM), which is a sandbox for user application, fits well in the education environment to provide computational resources for teaching and research needs. In resource management, they want to reduce cost...

How does a rm s investment change with its cash ow To study this question we collect detailed project level data on oil and gas lease auctions Bidding data on all tracts and bidders including losing ones allow us to track changes in relative bid prices and lease composition Morover outcome data for every lease i e whether minerals where found or not allow us to track changes in pro tability of ...

Accounting standard-setters have proposed that the right to use assets (including land and buildings) acquired under operating lease contracts should be recognised on the balance sheet of lessee companies. In recent years, several empirical research studies have investigated the potential impact of the proposed changes in accounting for leases. The current paper reviews this work and presents s...

This paper studies a software vendor’s decision to o¤er perpetual or lease-based licensing when customers are uncertain about their valuation for the software prior to adoption, and adoption requires an upfront implementation cost. First, in a discrete-time overlapping-generations model, I show that perpetual licensing can be more pro…table than lease-based licensing when consumer valuation unc...
