Similar to Levati and Neugebauer (2001), a clock is used by which participants can vary their individual contributions for voluntarily providing a public good. As time goes by, participants either in(de)crease their contribution gradually or keep it constant. Groups of two poorly and two richly endowed participants encounter repeatedly the weakest link-, the usual average contribution- and the best shot-technology of public good provision in a within subject-design. Some striking findings are that the weakest link-technology fares much better than the other two technologies in terms of welfare, and that the willingness of people to voluntarily contribute is greatly a®ected by the (increasing or decreasing) clock mechanism.
