have so far identified three broad types of think tank boards among the organisations and institutions that we have reviewed. The first type is the most common: a board of directors that is in charge of mainly two tasks: defining and maintaining the think tank’s original goals and values, and determining and ensuring its finances. These are corporate boards in the sense that they are quite similar to those of for profit organisations. They can also be referred to as legal boards, as their responsibility for the finances and appropriate functioning of the think tanks is determined by their country’s legislation. This board of directors usually appoints an Executive Director, who has the responsibility of overseeing the staff and all the think tank’s day to day activities.
