Board Interlocks as a Diffusion of Strategic Information – Does it Work? A Polish Case

Several theories point to the influence of board interlocks on the diffusion of important resources, mainly information. Empirical confirmation of the information functionality of the interlocking directorates network was obtained in the case of network research under the Anglo-Saxon model of corporate governance as well as the continental model in developed countries. Since the early 1990s another model of corporate governance in CEE countries has been developed. The specific determinants of the development of this model do not allow us to unequivocally state similar causes and consequences of interlocking directorates in relation to the most frequently studied western corporate governance models. The aim of this study is to determine the importance managers attach to these relationships within a corporate network as a source of strategic information that is important to the company’s strategic decision-making process, in the context of the Polish governance model. The research employs the case-study method and presents the results of five case studies of companies listed on the Warsaw Stock Exchange. The research, on the one hand, suggests that the network embeddedness of Polish listed companies is of minor significance; on the other hand, it pointed to the existence of two main types of corporate networks: one inwardly directed and focused on supervisory board members’ controlling function performed with a view to protecting the shareholders’ equity ownership, and the other orientated towards external relationships, often distant from the original industry, in order to obtain information that supports new initiatives. What seems to most determine the behaviour of company managers is the corporate culture resulting from the presence of a foreign owner from a Western European country. In general, the findings confirm the importance of the network of interlocking directorates more as an instrument of control than diffusion of strategic information.
