Information systems and the Internet have facilitated the creation ofused-product markets that feature a dramatically wider selection, lowersearch costs, and lower prices than their brick-and-mortar counterpartsdo. The increased viability of these used-product markets has causedconcern among...

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...

Cellular telephony and associated data services has been a major socialphenomena for well over a decade now. It has changed the way - in somecountries more than others - in which people communicate. In manycountries in Northern Europe and Asia, its penetration rates are veryhigh and in others...

We present an economic model of fixing or patching a software problem after the product has been released in the market. Specifically, we model a software firm’s trade-off in releasing a buggy product early and investments in fixing it later. We first show that patching investments and time to...

In spite of industry concerns, prior work has shown that Internet used book markets do not significantly cannibalize new book sales. In this research note we analyze similar data from markets for CDs and DVDs, goods that because of their digital characteristics may be more susceptible to...

With the rise of Napster, BitTorrent, and other tools facilitating Internet piracy, rights holders have understandably become very concerned with the development of strategies to mitigate the impact of piracy on sales. These tools fall into three general categories: litigation, countermeasures,...
