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 author reexamines the Schmalensee effect from a dynamic perspective. Schmalsensee's argument suggesting that high quality can be signaled by high prices is based on the assumption that higher quality necessarily incurs higher production cost. In this paper, the author argues that firms...

In this paper, we consider two firms diffusing incompatible technologies and their decision of consumer targeting. The technology adoption is made in two steps. First, once the firms sell their products to their respective targeted consumer, the technology is diffused successively by...

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 presents a model of quantity regulation as a policy variable when regulation enforcement is imperfect. The model provides a counterintuitive result: that equilibrium congestion can become worse as the quantity restriction becomes more severe. Intuitively, stricter regulation makes the...

The authors develop a model of cheap talk with multiple speakers in the presence of network externalities so that their utility functions are increasing in the network size. They first show that if there is no noise in private information that each sender receives, the full information is...

We consider the dynamic network formation problem under the requirement that the whole network be connected and remain connected after q nodes are destroyed. We propose the concept of dynamic Cq-stability and characterize dynamic Cq-stable networks for any qÏ0. Comparison with the outcome in...
