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...

Two consumers sequentially purchase at most one unit of some homogeneous good from a monopolist who knows the state of nature, either high or low. I characterize a rationing equilibrium at which the high-type monopolist produces only one unit and rations customers, whereas the low-type...

The emergence of Islamic Banks (IBs) with Sharia boards that restrict the set of permissible products and enforce prohibition of riba and gharar raises basic questions of how IB clients benefit by choosing financial services from a restricted menu of possibly higher-cost cash flows. Norms that...

This paper presents a model of quantity regulation aimed at mitigating externalities from over-use of a commons: for example, restrictions on use of automobiles, fisheries, computer networks and electronic stock quotation systems with high-frequency traders. The model provides a...

We consider the signaling role of attorney fees which have been usually assumed as exogenous in literature. We show that there exists an equilibrium in which the informed plaintiff uses both the attorney fee and the settlement demand as signals for his damage amount. If attorney service is not...

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,...

This paper discusses the possibility of signal jamming between multiple informed incumbents with conflicting interests and examines the implication of the possibility in the limit pricing literature. I find fully separating equilibria where the incumbent competing against the entrant does not...

Electronic money services are provided by the combination of Integrated Circuit (IC) cards and terminals. The compatibility of different brands of electronic money can be enabled by firms' joint adoption of standard terminals. In this paper, we analyse the effect of achieving compatibility among...
