Cultural Diversity and Innovation Performance of Multinationals

Describe the impact of cultural diversity on the innovation performance of MNCs.

Do you agree that innovation is more challenging in alliances involving subsidiaries of multinational companies (MNCs)? Is it related to the fact that they embody a dual background that encompasses the cultures of their host and home country? Can you suppose that the effect of cultural diversity is contingent on the content of the alliance, being positive in explorative and negative in exploitative alliances?
