Compatibility Choices in the Consumer Online Service Industry
No full textIn the information and telecommunications industry, among others, various kinds of innovative products are being launched. Due to the effect of network externalities on players* performances, the importance of the choice whether to make these products compatible with others cannot be overemphasized. This is also true of the consumer online service industry. Incumbent X.25-based providers are competing with each other and with other entrant Web-based providers and at the same time, trying to make their products compatible with others. Using a game-theoretic model, this paper examines how incumbent and entrant carriers strategically choose the compatibilities of their products. The welfare implications are also presented
Versioning of information goods under the threat of piracy
No full textThe present study investigates the effects of piracy on the quality decisions of a firm that produces two versions of an information good: that is, one version for a consumer with a high willingness to pay and a second version for a consumer with a low willingness to pay. On the assumption that there is no quality difference between the original and the illegal copy and that the cost of the copy is constant across users, we show that the presence of piracy induces the firm to choose a lower level of quality of the former and a higher level of quality of the latter relative to decisions made in the absence of piracy. We also discuss policy implications concerning the socially optimal level of copyright protection. (C) 2010 Elsevier B.V. All rights reserved.We thank Byong-Sam Choi for valuable comments and

No full textNMR Tools to Decipher Dynamic Structure of RNA
No full textIt is now well established that RNAs exhibit fundamental roles in regulating cellular processes. Many of these RNAs do not exist in a single conformation. Rather, they undergo dynamic transitions among many different conformations to mediate critical interactions with other biomolecules such as proteins, RNAs, DNAs, or small molecules. Here, we briefly review NMR techniques that describe the dynamic behavior of RNA by determining structural, kinetic, and thermodynamic properties.
