The purpose of this paper is two-folds. First, we examine the direction and the magnitude of substitutability or complementarity between information- and communication-related capital stock and various labor inputs to know about differential impacts of information and com-munication technology...

We examine factors determining productivity of information-technology service activities at firm level, using most comprehensive data of information service industries in Japan. We focus on the degree of modularisation and resulting outsourcing and economies/diseconomies of scale in software...

In many industries, competition is far from perfect and managerial efficiency (or a fixed cost) varies among firms. However, traditional measurement of technological progress assumes perfect competition and no fixed cost. This paper incorporates these two factors in the technological-progress...

This paper has three parts. First, we compile a new industry-by-industry data set of the Japanese economy in which information and communication technology (ICT) stocks are explicitly estimated and labor inputs are disaggregated with respect to age and education. Second, we investigate the...

This paper examines the direction and the magnitude of bias in the technological progress measurement caused by imperfect competition and fixed costs. We show that imperfect competition coupled with fixed costs is likely to make the traditional measurement of technological progress biased. The...
