This document consist of the abstracts for two papers which considered the impact of information technologies on political and economic systems. The first paper, "The Political Repercussions of Transnational Corporate Information Systems" (Terry Curtis), argued that information technologies are the most recent in a series of socio-technical systems developed to serve as infrastructure for social organizations, and that, as these technologies develop in both political and economic systems, they will effect the mix between relatively centralized political systems and relatively decentralized economic systems. The second paper, "New Information Technology and Economic Coordination" (Hajime Oniki), considered the effects of new information technology upon the way in which economic coordination is organized. It is argued that information technology has decreased both market cost and organizational cost, and also that the reduction in market cost is greater than the reduction in organizational cost. A mathematical model is constructed to describe these changes. (Author/EW)
