NGO aid is still widely believed to be superior to official aid (ODA). However, the incentives of NGOs to excel and target aid to the poor and deserving are increasingly disputed. We contribute to the emerging literature on the allocation of NGO aid by performing panel Tobit estimations for Swiss NGOs. The analysis offers new insights in two major regards:… (More)
We use experimental methods to study the power of leading by words. The context is a voluntary contribution mechanism with one-way communication. One group member can send a free-form text message to his fellow players. Contrary to the commonly-accepted wisdom that the cooperation-enhancing effect of communication requires the mutual exchange of promises,… (More)
Being closer to the poor, NGOs are widely believed to provide better targeted aid than state agencies. But empirical evidence is largely lacking. We contribute to closing this gap by drawing on an exceptionally detailed Swiss database that covers different forms of NGO aid and several official aid benchmarks. The differentiated Tobit estimations account for… (More)
In this paper, we use survey data to analyze the accuracy, unbiasedness, and the efficiency of professional macroeconomic forecasts. We analyze a large panel of individual forecasts that has not been analyzed in the literature so far. We provide evidence on the properties of forecasts for all G7 counties and for four different macroeconomic variables. Our… (More)
One-way communication has been found to substantially increase contributions in linear voluntary contribution mechanisms. We confirm the robustness of this result in the presence of income heterogeneity.
Formalin-fixed, paraffin-embedded (FFPE) tissues represent the most abundant resource of archived human specimens in pathology. Such tissue specimens are emerging as a highly valuable resource for translational proteomic studies. In quantitative proteomic analysis, reductive di-methylation of primary amines using stable isotopic formaldehyde variants is… (More)
We investigate leading by example in a public goods game in scenarios with and without intergroup competition. Leading by example is implemented via a sequential decision protocol. We examine both one-shot and repeated interaction and make use of the strategy method to characterize followers' conditional responses to the leader's contribution. The results… (More)
Koukoumelis et al. (2010, 2012) have shown that one-way communication enhances contributions to public goods. We investigate the effectiveness of one-way communication , when the benefits from the public good are asymmetric and the sender of a message is the main beneficiary of cooperation. Our results show that, in the absence of communication… (More)
