Representation, voluntary retirement, and shirking in the last term

There is disagreement over whether or not representatives shirk. Previous s tudies, however, have used raw interest group scores that do not allow for accurate comparisons over time. I take advantage of recently published inde xed ADA scores by Groseclose, Levitt, and Snyder (1999) that adjust for tem poral differences to test for shirking. I compare results from adjusted ADA scores to Poole and Rosenthal's Nominate scores. With a simple, straightfo rward test of dyadic representation, I provide additional evidence that shi rking exists among voluntarily retiring members of Congress.
