We consider a Stackelberg pricing problem in directed networks:Tariffs (prices) have to be defined by an operator, the leader, for a subset of the arcs. Clients, the followers, choose paths to route their demand through the network selfishly and independently of each other, on the basis of...

Network design and network synthesis have been the classical optimization problems intelecommunication for a long time. In the recent past, there have been many technologicaldevelopments such as digitization of information, optical networks, internet, and wirelessnetworks. These developments...

The Stackelberg pricing problem has two levels of decision making: tariff setting by an operator, and then selection of the cheapest alternative by customers. In the network version, an operator determines tariffs on a subset of the arcs that he owns. Customers, who wish to connect two vertices...

Wireless communication is used in many different situations such as mobile telephony, radio and TV broadcasting, satellite communication, and military operations. In each of these situations a frequency assignment problem arises with application specific characteristics. Researchers have...

We consider the problem of determining a set ofoptimal tariffs for a revenue maximizing operator, on a subset ofall arcs of a telecommunications network. We suppose multiplerational clients are active on the network who route their demandson the cheapest paths from source to destination, where...

We consider the problem of determining a set of optimal tariffs for an agent in the network, who owns a subset of all the arcs, and who receives revenue by setting the tariffs on the arc he owns. Multiple rational clients are active in the network, who route their demands on the cheapest paths...

This paper introduces a zero lower bound constraint on the nominal interest rate in a financial accelerator model with nominal and real rigidities. We .rst analyze the implicationsfor aggregate dynamics of binding the zero lower bound for shocks that depress the nominalinterest rate. We include...
