On the basis of a conditional contribution experiment conducted in Benin and Uganda, we argue that a conditional u-shaped profile exists, at least in poor communities. Under this profile, individuals invest considerably in public goods when nobody else does, reduce their commitment in reaction...

Public funding of water supply infrastructure in developing countries is often justified by the expectation that the time spent on water collection significantly decreases, leading to increased labor force participation of women. In this study we empirically test this hypothesis by applying a...

Ongoing empirical research on the drivers of project-aid effectiveness relies on World Bank evaluation ratings across heterogeneous aid sectors. This leads to two problems. First, it is difficult to identify which dimension of project performance World Bank evaluation ratings are measuring...

In this paper we argue that the recent evidence on individuals' decision making is of high relevance for the measurement of poverty when switching from a static and certain to a dynamic and uncertain framework. The numerous proposed measures of multi-period poverty and vulnerability have until...

70 percent of the rural population in sub-Saharan Africa does not use adequate sanitation facilities. In rural Benin, as much as 95 percent of the population has no access to improved sanitation. This paper explores why households remain without latrines analyzing a representative sample of 2000...

We analyze the drivers of presence (size of audience) and participation (number of questions asked) in parallel sessions at a large economics conference, using the annual meeting of the German Economics Association in 2012 as a case study. We find that the location of the presentation is at...

A considerable and increasing share of foreign aid stems from private donations. Hence, individual donors can increase social welfare in developing countries by directing their funds to the most effective NGOs. Surprisingly few studies have analyzed whether private donors care about aid...

This study analyzes the impact of gender and ethnic discrimination on redistributive preferences and productivity using a large online experiment with US citizens on Amazon's Mechanical Turk. Participants are randomly allocated to different payment schemes for a real-effort task. Four payment...

Empirical social sciences rely heavily on surveys to measure human behavior. Previous studies show that such data are prone to random errors and systematic biases caused by social desirability, recall challenges, and the Hawthorne effect. Moreover, collecting high frequency survey data is often...

We analyze the drivers of the size of the audience and number of questions asked in parallel sessions at the annual conference of the German Economics Association. We find that the location of the presentation is at least as important for the number of academics attending a talk as the combined...
