Can the Survivor Principle Survive Diversification

The survivor principle holds that the competitive process weeds out inefficient firms, so that hypotheses about efficient behavior can be tested by observing what firms actually do. This principle underlies a large body of empirical work in strategy, economics, and management. But do competitive markets really select for efficient behavior? Is the survivor principle reliable? We evaluate the survivor principle in the context of corporate diversification, asking if survivor-based measures of interindustry relatedness are good predictors of firms’ decisions to exit particular lines of business, controlling for other firm and industry characteristics that affect firms’ portfolio choices. We find strong, robust evidence that survivor-based relatedness is an important determinant of exit. This empirical regularity is consistent with an efficiency rationale for firm-level diversification, though we cannot rule out alternative explanations based on firms’ desire for legitimacy by imitation and attempts to temper multimarket competition.

Relatedness and Acquirer Performance

While the strategic management literature suggests that related diversification is superior to unrelated diversification, there is little evidence that acquirers benefit from pursuing related targets. We argue that the empirical literature is plagued by poor measures of relatedness. Moreover, many empirical studies do not control adequately for the characteristics of the market for corporate control. We argue that not only value creation, but also value appropriation, depend on the relatedness of acquirer and target. Using an improved measure of relatedness, we provide empirical evidence that acquirer returns are positively and significantly correlated with relatedness.

Diversification, Industry Structure, and Firm Strategy: An Organizational Economics Perspective

We review theory and evidence on corporate diversification, industry structure, and firm strategy from an organizational economics perspective. First, we examine the implications of transaction cost economics (TCE) for diversification decisions. TCE is essentially a theory about the costs of contracting, and TCE sheds light on the firm’s choice to diversify into a new industry rather than contract out any assets that are valuable in that industry. While TCE does not predict much about the specific industries into which a firm will diversify, it can be combined with other approaches, such as the resource-based and capabilities views, that describe which assets are useful where. We also discuss the transaction-cost rationale for unrelated diversification, which focuses on the potential efficiencies from exploiting internal capital markets. We review this argument as it emerged in the transaction cost literature in the 1970s and 1980s and, more recently, theoretical and empirical literature in industrial organization and corporate finance. We then discuss how diversification decisions, both related and unrelated, affect industry structure and industry evolution. Here, the stylized facts suggest that diversifying firms have a crucial impact on industry evolution because they are larger than average at entry, grow faster than average, and exit less often than the average firm. We conclude with thoughts on unresolved theoretical, methodological, and empirical issues and problems and provide suggestions for future research.

Recession, HR and Change

We document how the recession in the wake of the financial crisis created a general surge in pro-change attitudes and behavior. Next, we examine variation across firms with respect to this change boost. In particular we focus on how and why a firm’s use of HR-measures such as training, pay changes and layoffs matters. We find that training and layoffs increases the relative size of the effect, while pay cuts reduce it. We make sense of these findings by looking at managers’ choice among HR-measures as a signal used by employees to determine their employment risk. The level of employment risk is in turn linked to employees’ investments in change in a nonlinear, U-shaped fashion.

Why There? Decomposing the Choice of Target Industry

How do diversifying firms chose their target industries? We use two population-level samples and new measures of relatedness to decompose the determinants of diversifying entry into internal factors (firm-specific resources and capabilities) and external factors (industry attractiveness). Our approach captures a variety of sources and types of relatedness and includes measures of resource strength as well as resource relevance, giving us a highly general picture of the drivers of diversification.
