There is an ongoing debate among researchers and policy makers, whether informal sector employment is a result of competitive market forces or labor market segmentation. More recently it has been argued that none of the two theories sufficiently explains informal employment, but that the...

Using household survey data, this paper estimates the mortality impact of improved water and sanitation access in order to evaluate the potential contribution of water and sanitation investment toward achieving the child mortality targets defined in Millennium Development Goal 4. The authors...

Summary Households in developing countries are frequently hit by severe idiosyncratic and covariate shocks leading to high consumption volatility. A household's currently observed poverty status might therefore not be a good indicator of the household's general vulnerability to poverty. In the...

The numerous proposed measures of multi-period poverty and vulnerability have until now not taken into account the insights from behavioral economics. In this paper we argue that recent evidence on individuals' decision making is of high relevance for the measurement of poverty when switching...

Using household survey data from 40 developing countries, we estimate the mortality impact of improved water and sanitation access. We find that the average mortality reduction achievable by investment in water and sanitation infrastructure is 8 and 22 deaths per 1000 children born for basic and...

Continued population growth and increasing urbanization have led to the formation of large informal urban settlements in many developing countries in recent decades. The high prevalence of poverty, overcrowding, and poor sanitation observed in these settlements—commonly referred to as...

We investigate the empirical relationship between child mortality and fertility across 46 low and middle income countries. Specifically, we model the effect of mortality expectations and interdependent fertility preferences on fertility. The direct marginal effect of mortality expectations on...
