Evolutionary theory of business activity studies how firms are selected out of environments that they do not fit, but most existing work under-emphasizes the distinction between acquisition and dissolution as selection processes. We address this gap with a multi-level analysis that investigates how managerial and functional organizational capabilities affect whether struggling firms exit by acquisition or dissolution. We demonstrate that managerial and functional capabilities have heterogeneous effects on selection processes, with managerial capabilities having particularly strong influence on acquisition exits by struggling firms. The work provides a bridge between adaptation and selection views on organizational change; exit by dissolution represents selection of both firms and capabilities, while exit by acquisition represents firm selection but capability adaptation.Key words: Selection, capabilities, acquisition, dissolution, evolutionary theory, business dynamics 1 One of the fundamental tensions in strategic management theories of business evolution concerns the distinction between adaptation and selection when firms encounter problems. Early strategic management research typically assumed that business change primarily occurs by adaptation, in which executives of struggling firms actively lead strategic change of their underlying business capabilities (e.g., Cyert and March, 1963; Andrews, 1971). The evolutionary theory revolution of the 1970s and 1980s then highlighted the presence of strong firm-level inertia, which leads to population-level change in which many struggling firms fail to adapt and, as a result, exit from an industry Freeman 1977, 1989;Gort and Klepper, 1982;Nelson and Winter, 1982, 2002). Follow on studies have typically sought to demonstrate whether and when adaptation or selection tends to be the most pronounced force. What this debate has under-emphasized, though, is that different forms of exit -particularly, the contrast between shutting down and being acquired -have different implications for adaptation and selection. This paper argues that selection and adaption can occur concurrently at the firm and capabilities levels of analysis when one considers different forms of exit.We focus on the difference between business dissolution and business acquisition of struggling firms, emphasizing how different forms of exit reflect the evolutionary influence and fate of business capabilities. In particular, we argue that business dissolution entails a selection process that removes both a corporate entity and its underlying capabilities from the landscape, while acquisition represents a selection process that removes the corporate entity but preserves some of its organizational capabilities within the economic environment. We then argue that the extent of firm-specific managerial and functional capabilities influence whether a struggling firm exhibiting lackluster financial performance exits by acquisition or by dissolution. Hence, the paper studies mechanisms that shape micro le...
