PurposeThis study aims to understand the antecedents of export performance at the firm level. Building on agency theory but taking into account emerging market settings and institutional differences, the authors investigate how the board composition determines the export competitiveness of the firms operating in an emerging country from the point of view of corporate governance mechanisms.Design/methodology/approachUsing data from 221 exporting firms for four years (2007-2010), the authors find that there is a significantly positive relationship between board size and all measures of export performance, while a higher presence of outside directors on the board is negatively associated with export performance, consistently with expectations. The separation of chairman of board of directors and chief executive officer (CEO) positions has significantly positive impact on export performance. On the other hand, the authors find no support for the position that inside director professional representation neither reduce nor increase all measures of export performance of firms. In other words, the convergence with Western practices and consistently with agency theory’s claims is evident for both board size and CEO duality. However, the effects of inside professional and outside directors are no consistent with agency theorists’ expectations.FindingsUsing data from 221 exporting firms for four years (2007-2010), the authors find that there is a significantly positive relationship between board size and all measures of export performance, while a higher presence of outside directors on the board is a negatively associated with export performance, consistently with expectations.

However, exporting continues to be an important mode of internationalization for multinational companies, especially operating an emerging economy. This study is one of the first studies on the impact of governance factors such as board structure on only export performance rather than overall (firm) performance in light of international management. In other words, the study of the determinants of exports in the context of an emerging economy is an important contribution to the literature, given that our understanding of how the board composition determines the export competitiveness from the point of view of firms operating in an emerging country such as Turkey. Moreover, this research investigates this relationship at objective export performance dimensions using primary data set from listed and non-listed export firms.Practical implicationsThe current study offered in-depth information to multinational companies that aim to gain a competitive exporting advantage in Turkey. Further, the results of this study give managers an opportunity to see the reasons behind the success of the exporting firms from the point of view of corporate governance mechanism.Originality/valueIn this paper, the authors contribute to this recent stream of research providing evidence on the effects of governance mechanism on the export performance from the point of view of emerging countries. Building on agency theory but taking into account emerging market settings and institutional differences, and international management, the authors provide a new framework that models the linkages between board composition and export performance. This work helps us to gain a deeper understanding of how board dynamics contribute to the internalization of firms. Research in this area has been sparse, although some studies have linked governance with export intensity. In this effort, the authors differentiate from previous studies in several ways.
