Abstract
This study uses a new, fine-grained, firm-based measure of target resources to investigate the relationship between target resource type and acquirer stock market performance. Our findings suggest that the market punishes acquirers of knowledge-based resources more than those that buy property-based resources due to the perceived uncertainty regarding the value of targets' knowledge resources. In support of the underlying uncertainty argument, we find that managers announcing knowledge-based mergers provide more information in their press releases than those announcing property-based transactions. While prior studies have suggested that resource relatedness may moderate the resource type and acquisition performance link, our findings do not support either a direct or moderating relationship.
