As emerging markets have become significant economic entities in the new world economy, the evolution and composition of economic institutions in them has inspired a rich literature in the organizational sciences. Among the institutions that have received some attention are the large, diversified conglomerates and networks of closely affiliated businesses (Khanna and Palepu 2010; Ramamurti and Singh 2009). Given their increasing impor-tance, these groups have attracted scholarly attention from a variety of theoretical perspectives. For example, researchers have focused on insti-tutional environments (Chung Khanna and Rivkin 2001) and organi-zational capabilities (Amsden and Hikino 1994; Kock and Guillen 2001) as drivers of the organizational strategies and structural configurations of these groups operating in many emerging markets (EMs). Even with this increased attention, however, we still know very little about how firm capabilities and organizational strategies and the particular environments in which these emerge co-evolve over time and reflect the changes that underscore the nature of their institutional environments (Teece et al. 1997; Kock and Guillen 2001; Khanna and Palepu 2006). Among the questions that require exploration are at least the follow-ing. How do the reciprocal interactions between firms and environmental institutions affect organizational renewal, adaptation, and selection? How do organizational, institutional and market mechanisms shape, and how are they in turn shaped by, their economic, social and political environ-ments, independently and in concert? How do institutional isomorphism, interdependence and path-dependence create an environment of mutual and reciprocal influence between institutional change and organizational action? How do the institutional context and the internationalization 483 484 Institutional approaches to international business of firms interact; that is, are there any path-dependencies in the inter-nationalization of EM firms? Do these differ from those of developed country internationalizing firms? What roles do endogenous factors, such as managerial intent, knowledge and willingness to internationalize, and exogenous variables such as the nature of markets and institutions, affect internationalization patterns? How do the reciprocal interactions among these happen? For example, how have increased liberalization of international trade and investment regimes and the opening of markets that were once passionately protected by EM governments changed these firms' capabilities? What are the motivating forces that have driven EM multinationals out of their markets to date? Are these forces changing, and if so, how? What are the internationalization paths that EM firms have chosen to follow in light of these institutional transformations and market drivers? How different are these from those that have been followed by internationalizing firms from the developed Western economies in the latter part of the last century? While these questions have been explored in the literature to some extent (see, e.g., Yang et al. 2009), our knowledge of the answers to them remains shallow, evidenced by a recent Boston Consulting Group report (2010) which underscores this void in the literature. Yet, it seems natural that we can learn a lot about these issues from studies that consider the historical, cultural and evolutionary antecedents of firm behavior in these markets and their institutional contexts as co-evolutionary frameworks. We address this issue in this chapter by showing how Turkish internationalizing firms have evolved and function in the dis-tinctive institutional environment of Turkey in which they are embedded today, and how they have been propelling themselves into international markets during the recent past. While our work is exploratory and is based on our study of internationalizing firms in only one EM, Turkey, we believe that it is worthy of inspiring significant questions and future work on this interface in other EMs. Extending earlier work in this area (Carney and Gedajlovic 2002; Kock and Guillen 2001), we show how the institutional environments and organizational strategies of Turkish firms have co-evolved during the past nine decades (1923–2012) and that this co-evolution was complex and dynamic, yet interdependent. Our study draws from earlier work on business group (BG) behavior in EMs (Khanna and Yafeh 2007) and from work on Turkish BGs (Yaprak and Karademir 2010, 2011; Karademir et al. 2005; Goksen and Usdiken 2001). As that research stream shows, Turkish BGs share many common features with highly diversified BGs found in other emerging markets
