Elected representatives serving their …nal period face only weak incentives to provide costly e¤ort. However, overlapping generations (OLG) models suggest that exit prizes sustained by trigger strategies can induce representatives in their …nal period to provide such e¤ort. We evaluate this hypothesis using a simple OLG public good experiment, the central treatment being whether exit prizes are permitted. We …nd that a signi…cantly higher number of subjects in their …nal period contribute when exit prizes are permitted. However, this result does not originate from use of trigger strategies. More likely explanations include gift-exchange and focal-point e¤ects.
