The development of theoretical frameworks seeking to formalize thinking about why young, entrepreneurial firms internationalize (Brush, 1992; McDougall, Shane, & Oviatt, 1994; Oviatt & McDougall, 1997) led to an emerging empirical literature seeking to test these theories using real world data (Autio, Sapienza, & Almeida, 2000; Coeurderoy & Murray, 2008; Mudambi & Zahra, 2007; Fernhaber, Gilbert, & McDougall, 2008). We draw on elements of several established theories of internationization to provide a framework for exploring international market entry and scale of entry measured by number of foreign markets entered for a sample of young, high-tech, firms from the UK and Germany.
