In recent years corporate international diversification has become a widely used growth strategy for companies from both developed and emerging markets. Nevertheless, academic papers provide contradictory results on whether the influence of international diversification on firm performance is positive or negative. This chapter presents the results of an empirical analysis of corporate international diversification – performance relationship on a sample of companies from BRIC countries, which expanded geographically in 2005-2015. We contribute to the existing literature by applying a new methodology to identify the performance effects of corporate international diversification based on an economic profit measure. The results indicate that there is a non-linear relationship between the degree of international diversification and economics profit spread. Additionally, for BRIC companies international diversification on average does not have a significant impact on expected long term performance, measured by Tobin’s Q.

Using the SIPRI Arms Transfers Database covering all trade in military equipment over the period 1950–2018, we examine the relationship between countries from a novel empirical perspective. We consider the arms transfers network as a multiplex network where each layer corresponds to a particular armament category. First, we analyze how different layers overlap and elucidate main ties between countries. Second, we consider different patterns of trade in order to identify countries specializing on particular armament categories and analyze how they change their export structure in dynamic. We also examine how countries influence each other at different layers of multiplex network. Finally, we analyze the influence of countries in the whole network.
