Approaches without Proxies or Instruments

Approaches without Proxies or Instruments. In this video we consider possible approaches to identification of the causal effects of the policy.

In accordance with our view that such restrictions should be motivated on economic grounds, our discussion emphasizes and contrasts the economic content of different possible restrictions.
