The Whole Is More Than the Sum of Its Parts - Or Is It? A Review of the Empirical Literature on Complementarities in Organizations

The concept of complementarity and its role in the design of organizations has enjoyed increasing attention over the past twenty years. We provide a systematic review of the empirical studies on complementarities in leading journals in management, economics and related disciplines that considers the nature of the factors among which complementarities are found to exist, and the effects of complementarities in organizations. Our findings suggest that complementarities result from the skilful matching of heterogeneous resources which generate positive returns above and beyond the effect of each resource generated on its own. In contrast, the empirical evidence on complementarities between individual organizational and HR practices in firms provides mixed conclusions. We show that complementarities are likely to materialize in complex systems of multiple design elements. Therefore, future research should aim at uncovering complementary effects among multiple elements that capture organizational systems better than a few selected elements only do.Complementarities; Organizational Design

The Whole Is More Than the Sum of Its Parts— Or Is It? A Review of the Empirical Literature on Complementarities in Organizations

The concept of complementarity denotes the beneficial interplay of the elements of a system where the presence of one element increases the value of others. However, the conceptual work on complementarities to date has not progressed sufficiently to constitute a theory that would offer specific predictions regarding the nature of the elements that form complementary relationships or the conditions for their emergence. To advance our understanding of complementarities, the authors provide a synoptic review of the empirical studies on this concept in leading journals in management, economics, and related disciplines over the period 1988-2008. The authors find that whether a study provides evidence of complementarities in organizations is at least partially driven by its investigative approach. On the basis of the findings, the authors argue that complementarities are most likely to materialize among multiple, heterogeneous factors in complex systems. Therefore, the absence of complementary relationships between a limited set of individual factors may not negate the possibility of complementarities, but rather point to the need for including further systems-specific factors in the analysis. The authors conclude by providing directions for future theoretical and empirical research and outlining managerial implications of the work

Evaluating the Significance of Paleophylogeographic Species Distribution Models in Reconstructing Quaternary Range-Shifts of Nearctic Chelonians

<div><p>The climatic cycles of the Quaternary, during which global mean annual temperatures have regularly changed by 5–10°C, provide a special opportunity for studying the rate, magnitude, and effects of geographic responses to changing climates. During the Quaternary, high- and mid-latitude species were extirpated from regions that were covered by ice or otherwise became unsuitable, persisting in refugial retreats where the environment was compatible with their tolerances. In this study we combine modern geographic range data, phylogeny, Pleistocene paleoclimatic models, and isotopic records of changes in global mean annual temperature, to produce a temporally continuous model of geographic changes in potential habitat for 59 species of North American turtles over the past 320 Ka (three full glacial-interglacial cycles). These paleophylogeographic models indicate the areas where past climates were compatible with the modern ranges of the species and serve as hypotheses for how their geographic ranges would have changed in response to Quaternary climate cycles. We test these hypotheses against physiological, genetic, taxonomic and fossil evidence, and we then use them to measure the effects of Quaternary climate cycles on species distributions. Patterns of range expansion, contraction, and fragmentation in the models are strongly congruent with (i) phylogeographic differentiation; (ii) morphological variation; (iii) physiological tolerances; and (iv) intraspecific genetic variability. Modern species with significant interspecific differentiation have geographic ranges that strongly fluctuated and repeatedly fragmented throughout the Quaternary. Modern species with low genetic diversity have geographic distributions that were highly variable and at times exceedingly small in the past. Our results reveal the potential for paleophylogeographic models to (i) reconstruct past geographic range modifications, (ii) identify geographic processes that result in genetic bottlenecks; and (iii) predict threats due to anthropogenic climate change in the future.</p></div
