In this study, we conceptualize intraorganizational multiplicity of mental models as a complementary element that facilitates shifting from lower- to higher-level learning. Specifically, we investigate whether multiplicity of mental models¡ªproxied by four measures¡ªhelps acquirers to categorically adapt selection rules for legal advisors in mergers and acquisitions (M&As) from domestic toward international settings. In developing our conceptual framework, we integrate resource-based, social network, and organizational learning perspectives. Empirically, we draw on 11,511 acquisition attempts announced from 1998 to 2010 (completion/abandonment assessed as of January 10, 2015, at the latest). The results largely support our theory: First, choosing legal advisors in domestic and international deals calls for different selection rules. While in domestic deals, network-related characteristics are more important drivers of lawyers¡¯ performance relative to their country-specific expertise, the comparative relevance of these attributes is reversed in cross-border deals. Yet, initially, acquirers fail to recognize this. Also, they do not initially adjust their selection criteria appropriately in response to accumulating M&A experience of their own. Only after having attempted a substantial number of cross-border M&As, they reach a turning point at which they rebalance their selection criteria such that they reflect the predominant relevance of country expertise in cross-border settings. Finally, recognition of the need to categorically reassess selection criteria in international deals is significantly facilitated by an acquirer¡¯s multiplicity of mental models %K organizational learning %K experiential learning %K social networks %K legal advisors %K cross-border vs. domestic M&As %K acquisition completion %U https://journals.sagepub.com/doi/full/10.1177/0149206317753292
