Abstract: This paper is concerned with revealing and explaining patterns in the ways firms diversify into new products and industries. Shifting the focus from the observable similarity of products provided by the firm, to the less observable underlying resources required in different industries, can be a useful and interesting way of looking at patterns of diversification. The theory outlined in the paper suggests that firms diversify within groups of industries that are related to one another in the types of human skills and expertise required in each industry. Within these resource-related industry groups, firms can more efficiently utilize their resources by sharing and transferring them across similar products. The theory was tested with a sample of 12,781 diversified firms operating in all sections of the U.S. economy. Across the firms studied, much of a firm's diversification was found to be on average within resource-related industry groups and was consistent with the efficiency arguments developed. The study demonstrates the utility of looking at human expertise similarity to reveal and explain patterns in diversification. It suggests new ways of examining the concept of resources. It also suggests that the industry group, rather than the single industry, needs to be used to analyze the context where diversified firms operate. By looking at resource-related industry groups, the study encourages strategic thinking that views demand, competition, and relatedness of industries more broadly.
