— Using original data from an area of Zambia with contrasting tenure regimes (state and customary), the hypotheses are tested whether farmers with leases or titles have superior fixed investment and productivity to those without documentation. Results indicate that documentation is indeed associated with greater fixed investment independently of an array of control variables. Productivity also ...

Supplemental feeding is a tool for enhancing northern and some of the economic implications of feeding. This bobwhite (Colinus virginianus) populations on hunting leases in South Texas. Feeding may be used to improve winter survival, reproduction and/or harvest of birds. Before implementing a feeding program, operators should consider management goals and the factors limiting quail populations....

1 This work is supported in part by the EU 5 Framework Program, Contract No. IST-2000-25289. Abstract. We have developed JaWS, a Javabased web computing system, which enables users to effortlessly export their machines in a global market of processing capacity to host remote computations [6]. Leases are used to promote dynamic task placement as well as fair compensation for the host providers. ...

Lamport showed that a replicated deterministic state machine is a general way to implement a highly available system, given a consensus algorithm that the replicas can use to agree on each input. His Paxos algorithm is the most fault-tolerant way to get consensus without real-time guarantees. Because general consensus is expensive, practical systems reserve it for emergencies and use leases (lo...

Leasing has become a very important financial instrument today. A large amount of literature discusses the determination of lease rate. In this essay, we focus on the valuations of lease contracts and credit risk. First, we introduce both discrete and continuous time models to determine the equilibrium rate of risk-fiee lease contracts. Then, by relaxing the restriction of riskless leases, a mo...
