The accelerating effect of institutional environment unfamiliarity on subsidiary portfolio expansion in a new host country

In forming external networks in a host country, a foreign subsidiary acquires knowledge which contributes to the parent's stock of country-specific knowledge and capabilities. Building on this notion, we argue that an MNE unfamiliar with the institutional environment of a newly entered foreign country has an incentive to expand its subsidiary portfolio in that country at a higher rate. We test this using a longitudinal dataset of German public firms which made investments into 2220 new host countries between 1985 and 2015. We find that unfamiliarity accelerates subsidiary portfolio expansion most when the initial investment is a wholly-owned subsidiary, and that the effect becomes weaker over time. Our study contributes to the internationalization process literature by showing that being unfamiliar with a host country is not necessarily an obstacle to subsidiary portfolio expansion – indeed it can accelerate it.
