In this paper we analyze if an `urban mortality penalty\' exists for today\'s developing countries, repeating the history of industrialized nations during the 19th century. We analyze the Demographic and Health Survey (DHS) of 19 Sub-Saharan African countries for differences in child and adult...

With about five children born per woman and a population growth rate of 2.5 per cent per year, sub-Saharan Africa has been the world's fastest growing region over the last decade. Economists have often argued that high fertility rates are mainly driven by women's demand for children (and not by...

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...

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...

Survey data on income and expenditure is often of low quality and does not capture the volatile and irregular nature of cash flows of poor households. Financial diaries are increasingly used to improve the precision and accuracy of consumption and income estimates. In this paper we analyze...

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...

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...

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...
