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...

In this paper, the authors provide a rationale for why firms issue gift cards or vouchers. Mainly, issuing gift cards can be considered as a collusion-facilitating practice. A firm that issues gift cards can raise its price for several reasons. First, the discounted price by the face value of...

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 q≥0. Comparison with the outcome in...
