Our numerical evidence shows that the analytical approximation is extremely accurate across all expiries.
For the purpose of studying the free boundary profile near expiry, many different integral equations have been derived [1, 3, 8, 14, 17].
Interpolating this infinite horizon behaviour and a known near-expiry behaviour, two simple analytical approximation formulas for the optimal exercise boundary are proposed.
In 6 the behavior of free boundary near expiry is analyzed.
This involved upholding the earlier decision of 1769 to charge increased rents upon leases that were still five years from their legal expiry date.
Our first case handles equipment code star t-up and expiry caused by model year change, for which we use the 6d-method.
These are par ts exchange, equipment code star t-up and expiry, and assembly line reconfiguration.
A time limit would be set, at the expiry of which the run would end, with the handler keeping his points earned until then.
