Technological change in the military aircraft industry

This paper analyzes technological change in the U.S. military aircraft industry. It divides this technological change into two components, methods of production and product quality innovations. The basic findings of this paper are obtained from a comparison of the F-4 and F-15 technologies. The results show that new production technologies reduce the costs of manufacturing a weapon system, but that product improvements substantially increase costs.     

“Ideas” driven growth: the OECD evidence

This paper estimates the parameters of the ideas production function crucial to recent ideas-driven growth models. Using U. S. patents granted to residents in OECD countries to generate the stock of commercially used ideas, we provide evidence for two main findings. First, at the level of the production of ideas, we find evidence of increasing returns to scale in the stock of ideas and number of researchers, but marginal decreasing returns in each one of these factors. Second, we provide evidence of the association between ideas growth and economic growth for the OECD as a whole in the long run.JEL Classification: 031, 040The author would like to thank the helpful comments made by two anonymous referees, and by the editor, of the PEJ. The helpful discussions with Professor Mário Rui Silva are grateful acknowledged, too.

The relationship between technology adoption and strategy in business-to-business markets : The case of e-commerce

Firms have been traditionally advised to adopt information and communication technologies (ICT) to support the achievement of existing business objectives. However, entry into business-to-business e-commerce may require the concurrent adoption of new business strategies. This paper argues, therefore, that ICT analysis needs to be considered at the same time and at the same strategic level, as internal, competitor and market analysis. This is because the source of the competitive advantage brought by ICT has changed, to be largely obtained through increase in customers' perceived value. The literature presents a confused picture of the likely consequences to a firm of its adoption of e-commerce. This paper concludes that any such adoption must be evaluated in the environment of the individual firm. A multidimensional analytical framework, taking a combined informational and marketing perspective, is presented to assist with such evaluations.     

The effectiveness of entrepreneurial firm’s knowledge acquisition from a business incubator

This cross-cultural research project, involving the United States and Finland, explored how the entrepreneurial firm’s acquisition of business processes’ knowledge from interaction with incubator management positively impacts on new product development, increased technical competence, enhanced reputation and lower costs of sales to customers. In a sample of 52 firms, the study’s methodology depended on single response, self-reported data. The findings suggest that the sole knowledge benefits gained by the firm, from the incubator relationship, is a perception of enhanced reputation. Also, incubator managers should focus more on assisting new technology based firms with growing the venture in the marketplace. Funding for this project was provided by The National Science Foundation, and The National Technology Agency of Finland.
