We find:
1. Relaxing search frictions improves access to foreign goods, but relaxing both search *and* trust frictions (adverse selection + moral hazard) is needed to form meaningful relationships.
2. Smartphones + social media can lower these frictions and allow small firms to import directly.

2 was started at MIT recently and has been very useful, but if forced to choose I’d do 1.
