Using a real-options approach to endogenously derive the entire term s
tructure of lease rates, I develop a unified framework for pricing a w
ide variety of leasing contracts. The structure of the model is analog
ous to traditional models of the term structure of interest rates. I s
how how the model is flexible enough to determine equilibrium lease ra
tes for leases of any term and practically any structure, including fo
rward leases, leases with options to renew or cancel, lease insurance
contracts, adjustable-rate leases, and leases with payments contingent
on asset usage.
