Research Joint Venture and Open Economy

The consumer surplus under the open economy is greater than that under the closed economy from the viewpoint of social welfare. This indication has been proved when only the product market is considered. This article is to show how this result is changed if the R&D market as well as the product market is considered. We find the possibility that the closed economy is preferred to the open economy in case of the (international) R&D joint venture.     

Neue Netzzugangstechnologien — Schlüssel zu Multimedia-Anwendungen

World-wide, telecommunication is marked by three basic conditions:

1. the market demand of new services;
2. the politically stimulated liberalization of the telecommunication market and
3. the technical possibilities of new telecommunication technologies.

Network operators are confronted with the task to yield high interests within a short time with limited investment possibilities. Therefore, the access network and the technologies linked to it have an increasing importance for the economic success on a liberalized telecom market. This article describes the most distinguishing aspects of an access network, its positioning within a telecom system, and the most important technological developments in this field: use of fibres in the access area, FITL systems, multimedia transfer via the copper twisted pair by means of xDSL technologies and via CATV networks by means of HFC technologies.

Upward influence styles of R&D project leaders

Innovation is not only a technological but also a sociopolitical process of contested change, which implies that the fate and the result of an R&D project are shaped by how influence is exercised. As a means of encouraging internal entrepreneurial efforts, the capacity of project leaders to successfully influence others has been widely discussed. Nevertheless, only a few studies have systematically investigated the influence behaviors of project leaders. Due to the lack of previous empirical research, we do not know much about the influence behaviors of project leaders, nor about how to manage this phenomenon, if it can be done at all. To address this gap, this study draws on a social influence framework for understanding the upward influence behaviors of the R&D project leaders. The authors propose and test a model that the influence styles used by project leaders are affected by personal, task, and relational factors and in turn affect the project performance. The empirical data of 83 ongoing projects collected from 22 Korean public and private R&D institutes in the electronics/telecommunication, machinery, and chemical industries are analyzed. The results reveal that: (1) project leaders differ not only in the general level of influence but also in how to mix various influence tactics; (2) personal characteristics (need for achievement and self-monitoring) affect the selection of influence styles (that is, tacticians, shotguns, and bystanders) of project leaders; and (3) the influence styles used by project leaders, in turn, have an effect on team performance through the influence that project leaders have on other people. Based on these findings, several theoretical and practical implications related to upward influence behaviors of project leaders and some areas for future research are discussed     

Determinants of Corporate R&D Investment: An Empirical Study Comparing Korea's IT Industry with Its Non‐IT Industry

In our study, we extracted the market, finance, and government factors determining R&D investment of individual firms in the IT industry in Korea. We collected the financial data of 515 individual firms belonging to IT and non‐IT industries between 1980 and 1999 from the Korea Investors Service's database and investigated the empirical relationship between the factors using an ordinary regression model, a fixed effects model, and a random effects model. The main findings of our study are as follows: i) The Herfindahl Index variable representing the degree of market concentration is statistically insignificant in explaining R&D expenditures in the IT manufacturing industry. ii) Assets, which is used as a proxy variable for firm size, have a positive and statistically significant coefficient. These two results suggest that the Schumpeterian Hypothesis may be only partially applied to the IT manufacturing industry in Korea. iii) The dividend variable has a negative value and is statistically significant, indicating that a tendency of high dividends can restrict the internal cash flow for R&D investment. iv) The sales variable representing growth potential shows a positive coefficient. v) The subsidy as a proxy variable for governmental R&D promotion policies is positively correlated with R&D expenditure. This suggests that government policy has played a significant role in promoting R&D activities of IT firms in Korea since 1980. vi) Using a dummy variable, we verified that firms reduced their R&D investments to secure sufficient liquidity under the restructuring pressure during Korea's 1998 and 1999 economic crisis.
