Abstract: 
Introduction. The development of information and communication technology (ICT) and digitalization of the society, which have been spreading around the world as a result of swiftly growing smart industry (Industry 4.0) are usually associated with an increase in production output and labour productivity and a reduction in manufacture and customization costs.
Problem Statement. According to the Solow Paradox (1987), investments in computer equipment and technology are not accounted in economic statistics on increasing labor productivity as a result of computerization, which undermines the conception of favorable impact of electronics on production output and labor productivity.
Purpose. To develop requirements for improving the economic and mathematical models for measuring the ICT effect on production output, based on the analysis of the advantages and shortcomings of the existing models of the computer technology and software effect on production output and the peculiarities of ICT development.
Materials and Methods. The historical method for analyzing the development of models of ICT effect on production output, the comparative analysis of existing economic and mathematical models to determine the approaches to the selection of factors influencing the performance indicators, and the analysis of arrays of the initial statistic data.
Results. Analyzed models and the course of their development have shown a favorable impact of ICT on production output and labor productivity. The Solow Paradox is explained by the fact that the share of computer equipment and technology in corporate fixed assets in the late 1980s — the early 1990s was insignificant, as well as by the lack of reliable statistics at that time and an imperfect methodology for its analysis. With the development of statistics as science and with the spread of computer equipment and technology, the Solow Paradox has been rejected in new models of ICT effect on production output.
Conclusions. A set of models that take into consideration the institutional features of the national economic development, the life cycle stages, and the degree of implementation of digital technologies shall be used in order to clarify the ICT effect on production output and labor productivity. The models of ICT effect on production output need to be further elaborated for taking into consideration the specifics of development of cutting-edge information technologies.
