It has recently been argued that the informal sector of labor markets in de- veloping economies shows a dual structure with part of the informal sector being competitive to the formal sector and part of the informal sector being the result of market segmentation. To test this hypothesis, we...

It has been recently argued that the informal sector of the labor market in a developing economy shows a dual structure with one part of it being competitive to the formal sector and another part being the result of market segmentation. To test this hypothesis we formulate an econometric model...

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...

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...

The aim of this paper is to expand our knowledge on risk aversion among the poor by conducting experiments that do not only test risk aversion in small and large stakes but also in risky gains and risky losses. To our knowledge, this is the first attempt to conduct experiments in poor...

Given the current focus of international development policy on pro-poor growth and poverty reduction, the role of the informal sector in the process of economic development is again at the top of the research and policy agenda. A key question is if pro-poor growth policies have to address the...
