This document presents a research effort intended to improve the economic information available for formulating politics and making decisions related to Information Analysis Centers (IAC's) and IAC services. The project used a system of IAC information activities to analyze the functional aspects of IAC services, calculate the present value of net benefits, and examine the sensitivity of the costs and benefits to changes in variables and to technological developments. The document includes eight chapters and five appendices. Chapter two examines IAC activities. Chapter three establishes the conceptual framework for modeling demand for IAC services. Chapter five describes an IAC user decision model. Chapter nine summarizes the findings and conclusion of the research effort. An executive summary is also presented. The study recommends that IAC's continue to improve accounting systems that provide meaningful cost allocation data, especially professional staff time. (Author/HM)
