In this book, the focus is on post-merger intercultural integration, effective communication between the relevant cultures and the different politeness strategies adopted by them. It is argued that cultural differences are a key issue in misunderstandings and miscommunication, which can affect a smooth post-merger integration, thereby focusing on differences between the Australians, US-Americans, Germans and the Swiss. The research contributes to bridge the gap between pragmatics, sociolinguistics and intercultural management studies. The empirical findings identify a company's social dimensions and execution skills as strategic sources of competitive advantage in cross-border M&A activity.
