With the premise that patent data are reliable indicators of innovativeness, the empirical analysis of R&D?patents relationship is useful for monitoring the efficiency of the innovation process. This paper extends the research on the relationship between R&D spending and patent counts by...

The paper analyzes how adding alternative fuel passenger cars to the market will affect patterns in demand for passenger cars. We use conjoint analysis and a multiple discrete-continuous choice model to estimate consumer preferences regarding alternative fuel vehicles, and based on the estimates...

As global concern about climate change increases, the need to control and mitigate greenhouse gas emissions is likely to emerge as a worldwide policy agenda. We determined world-wide carbon dioxide (CO2) emission trends and six underlying forces driving emissions from the industry sector with...

Since electricity market restructuring, questions over adequate levels of R&D investments persisted. Using an unbalanced panel data of 70 electricity-generating firms across 15 Organisations of Economic Co-operation and Development countries from 1990 to 2008, this paper empirically examines the...

To understand the impact of Information Systems (ISs) on actual performance, we employed 616 Korean firms to estimate the complementarities among such systems and to uncover the contextual factors influencing them. In particular, we introduced various contextual variables and analysed their...

Although numerous papers have examined the ways in which firms can improve their innovative performance through technology alliances, empirical research on the effect of contract structures in technology licensing has been scarce. This study provides evidence that the payment mechanisms agreed...

This study attempted to identify the relationship among user demand for online music, unauthorized file-sharing activities (piracy), and the effect of digital rights management (DRM) in Korea. Empirical analysis showed that piracy and DRM have negative effects on the demand for online music. In...

The paper suggests a different model for estimating a discrete/continuous choice framework using Gibbs sampling. The basic idea of using Gibbs sampling for the multinomial probit model is extended to the case of a discrete/continuous framework. To check the applicability of this method, it was...

The liberalization of telecommunications is largely based on the premise that increasing competition will encourage investment. The hypothesis that liberalization promotes investment has received the most empirical support in recent research. However, a key question that has been largely ignored...
