The value of information systems availability is analyzed in this study through theoretical models of information economics. The article employs the information structure model to assess the values of information systems under various situations, with particular examples of the impact of data accessibility level on the quality of decision-making. The study centers on the relationship between the information system's time and content characteristics and the value of the information. It suggests a method to model the utility considerations that lead to the choice of an information system. The entailed models are employed to illuminate certain facets of the productivity paradox. The results of the analysis indicate that there is a direct relationship between systems accessibility and its informativeness. Consequently, there are some aspects of the "Productivity Paradox" that may be explained by using these results. The article proves a number of theorems and discusses the theoretical and practical interpretation of the results.
