The last question is to Mr. Globerman.
I'm interested in the connection between ownership and research and development. I listened to your words very carefully. You were very concrete about relying on empirical evidence in terms of the association between foreign ownership and efficiency.
Your words on R and D were that it's not necessarily true that research and development follow ownership. We've all seen in the broader technology sector what happened, say, with Nortel. The divisions of Nortel were carved up and sold off to foreign companies, and we lost what was one of the largest private funders of research and development in this country. We saw their R and D leave. I'm just wondering if there is any empirical evidence that research and development generally flow where the ownership of a particular entity goes. It seems intuitive that this would be the case. Is there any evidence?
