A decade ago, the German Advisory Council to the Federal Government on Global Environmental Change (Wissenschaftlichen Beirats der Bundesregierung für Globale Umweltveränderungen - WBGU) published its main report. This attempt to take stock in 2011 made an impact and provided orientation on...

Vor einem Jahrzehnt wurde das Hauptgutachten des Wissenschaftlichen Beirats der Bundesregierung für Globale Umweltveränderungen (WBGU) veröffentlicht. Dieser Versuch einer Bestandsaufnahme im Jahre 2011 hat national und international Impulse gesetzt und Orientierung gegeben. Der WBGU ging...

We derive a necessary and a sufficient condition for Nash implementation with a procedurally fair mechanism. Our result has a nice analogue with the path-braking result of Maskin [Nash equilibrium and welfare optimality, Rev. Econ. Stud. 66 (1999) 23-38.], and therefore, it allows us to give a...

Is there a way of matching donations that avoids crowding out? And, more generally, what is the best way to utilize a bigger lead gift for raising smaller contribu-tions in a fundraising campaign? To answer these questions, we present a novel matching method, some simple theoretical...

We present evidence from a natural field experiment and structural model designed to shed light on the efficacy of alternative fundraising schemes. In conjunction with the Bavarian State Opera, we mailed 25,000 opera attendees a letter describing a charitable fundraising project organized by the...

When asking for donations, charitable organizations often use suggestions concerning the amount of potential contributions. However, the evidence concerning the effects of such suggestions is scarce and inconsistent. Unlike the majority of existing studies concerned with small-money...

We present evidence from a natural field experiment and structural model designed to shed light on the efficacy of alternative fundraising schemes. In conjunction with the Bavarian State Opera, we mailed 25,000 opera attendees a letter describing a charitable fundraising project organized by the...

Is there a way of matching donations that avoids crowding out? We introduce a novel matching method where the matched amount is allocated to a different project, present some simple theoretical considerations that predict reduced crowding out or more crowding in (depending on the degree of...

Private wealth is a crucial factor for the economic well-being of households. Key determinants of private wealth include intergenerational wealth transfers (gifts and inheritances), which are gaining importance since 1990, as research suggests. We conduct a detailed investigation of the...

While increasingly popular in many domains crowdfunding remains largely un-derresearched and little is known about the best way to encourage participation. In a field experiment we vary suggested amounts and test different wordings for a campaign to finance a club good - an institute's summer...
