Abstract: 
I derive the exact small sample properties of the instrumental variables estimator using a trigonometric approach. The distribution for the estimation error is decomposed into a product of three components - each with an intuitive interpretation. This approach helps the discussion on what underlies the exact shape of the estimator’s distribution and in particular the possibility of a bimodal distribution.
