A Schumpeterian approach to entry barrier and firm profitability: cycle time of technology
ABSTRACT Entry barrier has long been considered as a major determinant of firm profitability. Although a less competitive market structure has been commonly known as an indicator of an entry barrier, pieces of past empirical evidence are mixed. Moreover, technological factors, such as R&D intensity, have also been considered. However, no satisfactory empirical analysis has been made, mostly due to the lack of a suitable proxy variable that can reflect the technological environment of a sector. This study addresses this problem by trying a new proxy variable, cycle time of technologies (CTT), and shows, using the US firm data, that firms in a sector with a long CTT tend to enjoy higher profitability and values than others. A long CTT of a sector presents a high entry barrier against any entrant because in such sectors, an existing stock of knowledge tends to be important for a longer period of time, making new innovation continuously rely on old knowledge owned by incumbents and protected by patent rights.
期刊介绍:
Economics of Innovation and New Technology is devoted to the theoretical and empirical analysis of the determinants and effects of innovation, new technology and technological knowledge. The journal aims to provide a bridge between different strands of literature and different contributions of economic theory and empirical economics. This bridge is built in two ways. First, by encouraging empirical research (including case studies, econometric work and historical research), evaluating existing economic theory, and suggesting appropriate directions for future effort in theoretical work. Second, by exploring ways of applying and testing existing areas of theory to the economics of innovation and new technology, and ways of using theoretical insights to inform data collection and other empirical research. The journal welcomes contributions across a wide range of issues concerned with innovation, including: the generation of new technological knowledge, innovation in product markets, process innovation, patenting, adoption, diffusion, innovation and technology policy, international competitiveness, standardization and network externalities, innovation and growth, technology transfer, innovation and market structure, innovation and the environment, and across a broad range of economic activity not just in ‘high technology’ areas. The journal is open to a variety of methodological approaches ranging from case studies to econometric exercises with sound theoretical modelling, empirical evidence both longitudinal and cross-sectional about technologies, regions, firms, industries and countries.
