Between 1993 and 1999, there were 93 acquisitions in the US drug industry (biotechnology1 and pharmaceutical industries com- bined), which had an average of 330 firms each year during the time period. One quarter of the acquirers were foreign companies, and three quarters were domestic. This study clarifies the difference in motivation for acquisitions between foreign and domestic acquirers of the US drug industry, with a particular focus on the motivation to source technology. The primary method used in this study to reveal the acquisition motivation is examination of the characteristics of the target firms in comparison with those of their acquirers. Traditional technology- sourcing investigations, starting with Kogut and Chang (1991), compare industry-level R&D industry of home and host country to determine motivation for foreign direct investment (FDI). This paper extends the traditional analysis from the industry level to the firm level.2 An initial analysis of the acquisition pairings reveals that the absolute difference between R&D intensity of the target and acquirer does not differ drastically between foreign and domestic acquisi- tions. This predicts that the acquisition patterns with respect to Received: 22 July 2003 Revised: 23 June 2004 technology sourcing do not differ between the two types of acquirer.

It is possible for technology sourcing to distribute an existing innovation. An explanation occur even when both parties have high R&D for these results may lie in the fact that the US is intensity if the research is in different areas. expending the most amount of R&D in the world Because her study does not identify research biotechnology industry, and foreign acquirers with streams, it is impossible to determine whether low R&D intensity may be attempting to use their technology sourcing had occurred.
