ABSTRACT
This chapter summarizes and compares the results of the market share and survival analyses conducted on both the complete and conservative samples. The complete and the conservative samples are comprised of 106 and 83 unique firms respectively. Each of these firms manufactured and sold implantable pacemakers between 1959 and 1990. The relationship between market share and market size is only significant and positive for the expanded model for the years 1970 through 1990. The significant negative relationship between industry density on entry and firm market share may be indicative of a difficult/more saturated competitive environment. The chapter discusses the estimates of the firm’s innovation/adoption history and firm and industry level control variables on the probability that it will survive acquisition and the probability that it will survive dissolution. Older firms offer a different set of desirable and complementary assets; such as reputation, industry distribution channels and a broad product line, which would also make them attractive candidates for acquisition.
