Take one hour to answer both questions.

1. An approach used to study the role that institutions play in shaping policy is to begin by identifying what social scientists refer to as an "iron triangle"? First, describe what an iron triangle is. Make sure that you specify the formal and informal relationships that connect the corners. Second, what type of triangle shaped the Social Security Act of 1935. And third, describe what has happened to the triangle since 1935?

2. Hall and Taylor describe three types of institutionalist approaches. Select one, state how it defines institutions, and -- using an example -- describe the value-added of such an approach to the study of public policy.
