In addition to the wireless telephony boom, a similar exponentially increasing trend in wireless data service--for example, short message service (SMS)--is visible as technology advances. We develop a structural model to examine user demand for voice service and SMS. Specifically, we measure the...

We present a model to investigate the competitive implications ofelectronic secondary markets that promote concurrent selling of new andused goods on a supply chain. In secondary markets where supplierscannot directly utilize used goods for practicing intertemporal pricediscrimination and where...

Peer-to-peer networks have emerged as a popular alternative to traditional client-server architectures for the distribution of information goods. Recent academic studies have observed high levels of free-riding in various peer-to-peer networks, leading some to predict the imminent collapse of...

Peer-to-peer (P2P) services allow users to share networked resources, notably bandwidth and content, from the edges of the network. These services have been popularized because of file sharing - particularly the sharing of unlicensed copyrighted files. However, content owners are increasingly...

Peer-to-peer (P2P) services allow users to share networked resources, notably bandwidth and content, from the edges of the network. These services have been popularized because of file sharing - particularly the sharing of unlicensed copyrighted files. Concerns about such P2P file sharing were...

In addition to the wireless telephony boom, a similar exponential increasing trend in wireless data service - short message service (SMS) - is visible as technology advances. We develop a structural model to understand how mobile users behave, especially how they consume voice, and services....
