140 countries have adopted bans on exports of antiquities, in part because these are seen as needed to protect cultural heritage for future generations. However, if enforcement is imperfect, export bans may be counterproductive, spurring the growth of a black market trade which can damage objects and obscure the archaeological record. We argue that allowing fixed-duration, long-term leases of a...

Logistic regression results indicate tenant's age, capital position, and relationship with landlord were more important than leased land use or crop management variables.

As virtual machines (VMs) are used for a wider range of applications, we encounter the need to integrate virtual machine provisioning models into the current site resource management infrastructure as seamlessly as possible. To address such requirements, we describe an approach to VM management that uses the ideas of multi-level scheduling to integrate VM provisioning into existing job schedule...

Since the 1980s, most of the oil and gas tracts auctioned by the federal government in the Gulf of Mexico are adjacent to tracts that are already under lease. Owners of neighboring leases enjoy incumbency advantages that act as a barrier to entry for other firms. We ask whether owners of neigboring leases take advantage of their situation and agree not to compete. To answer this question, we de...

We study options on short-term leases for capital-intensive equipment performing specific functions and services, such as leases for semi-submersible drilling rigs, marine seismic services, corporate real estate leasing, retail space leasing, and apartment leasing. We quantify the effect of an important factor in pricing options on these services: idle time between consecutive lease contracts. ...

Distributed systems require strategies to detect and recover from failures. Many protocols for distributed systems employ a strategy based on leases, which grant a leaseholder access to data or services for a limited time (the lease period). Choosing an appropriate lease period involves tradeoffs among resource utilization, responsiveness, and system size. We explain these tradeoffs for Jini Ne...
