Bellman equations for terminal utility maximization with general bid and ask prices
Słowa kluczowe:Bellman equation, bid and ask prices, optimal stopping, terminal utility maximization
In the paper we solve a system of Bellman equations for finite horizon continuous time terminal utility maximization problem with general càdlàg bid and ask prices. We assume that we have a restricted number of transactions at time moments we choose. The main result of the paper says that we can find a regular version of solutions to the system of Bellman equations, which enables us to find the form of nearly optimal strategies.
