Digital-age technologies promise to revolutionize the market for academic journals as they have other media. We model journals as intermediaries linking authors with readers in a twosided market. We use the model to study the division of fees between authors and readers under various market structures, ranging from monopoly to free entry. The results help explain why print journals traditionall...

We investigate dynamic adaptation policies for rate adaptive multimedia streams in a network where each route traverses at most one bottleneck link. Dynamic adaptation allows clients to dynamically adapt the stream subscription level, i.e., time-average stream rate, in response to changes in available link capacity, and allows the system to maintain a lower blocking probability than is possible...

This paper studies the impact of ad-avoidance behavior in media markets. We consider a situation where viewers can avoid advertisement messages. As the media market is a two-sided market, increased ad-avoidance reduces advertisers’ value of placing an ad. We contrast two financing regimes, free-to-air and pay-TV. We find that a higher viewer responsiveness to advertising decreases revenues and ...

The online content market for news and music is changing rapidly with the spread of technology and innovative business models (e.g. the online delivery of music, specialised subscription news services). It is correspondingly hard for suppliers of online content to anticipate developments and the effects of their businesses. The paper describes a prototype multiagent simulation to model possible...

this notion by saying client (i, r) has a minimally acceptable adaptivity parameter ai,r, which can be interpreted as a client’s individual QoS requirement. To emphasize this distinction between provider and client definitions of minimally acceptable stream resolutions, consider the example of a content provider offering a certain media stream with adaptivity a and maximum subscription level s....

Managing subscription journals and open access charges together has created challenges which may in part be dealt with by offsetting the two revenue streams against each other. In order to do this, it is necessary to have reliable financial data about the extent of the two interacting markets. Jisc Collections has been undertaking data collection regarding universities’ article publication char...
