要旨:
The provision of public goods is often hindered by a lack of powerful institutions that can sanction free riders or otherwise enforce private contributions to the public good. The simple deposit based solution introduced by Gerber and Wichardt (J Public Econ 93:429-439, 2009) solves this problem, but may require prohibitively large deposits, in particular in the context of intertemporal public goods. In this paper, we propose a modification of the deposit solution that relies only on comparably small deposits. The proposed modification improves the applicability of the procedure, most notably as it also allows to reduce deposits in static public goods problem by transforming them into dynamic ones with small per period contributions.
