In this paper, we consider the network as an alternative communication channel to undirected advertising in the market. The main distinctive feature of the network-embedded transaction is the interdependency of buyers' purchasing behavior. Since most transactions in a network are made...

We investigate a dynamic model of network marketing in a small-world network structure artificially constructed similarly to the Watts–Strogatz network model. Different from the traditional marketing, consumers can also play the role of the manufacturer's selling agents in network marketing,...

We introduce a new notion of connectivity, what we call weak connectivity, in a directed network where communication is one-way, and show that weak connectivity is equivalent to the usual concept of connectivity if the outdegree of each node is at most one, referred as the [DC] condition. Based...

This paper extends the literature on the optimal switching rule between two investments by considering the case where switching between investments is costly. The model builds on the classic framework of the multi-armed Bandit problem by explicitly incorporating two key assumptions. First,...

In this paper, we consider the network as an alternative trading environment to the market. The main distinctive feature of the network transaction is the dependence of buyers' purchasing behavior, which makes all consumers not equally valuable to a seller. We characterize the optimal behavior...

We model a hierarchy consisting of possibly corrupted agents who process information, and consider the problem of designing the efficient hierarchy structure and configuring the agents who differ in their honesty. If the only role of agents is to report the information to their direct superior,...
