Medical research indicates that breastfeeding suppresses post-natal fertility. We model the implications for breastfeeding decisions and test the model's predictions using survey data from India. First, we find that breastfeeding increases with birth order, since mothers near or beyond their...

In the case of natural monopolies there tends to be a trade-off between a higher quality of output provided by private firms, and a better access for poor consumers provided by public firms. This is partly the reflection of differences in objectives by private and public firms. The former tend...

We propose a unified growth theory to investigate the mechanics generating the economic and demographic transition, and the role of mortality differences for comparative development. The framework can replicate the quantitative patterns in historical time series data and in contemporaneous...

This paper provides a unified theory of the economic and demographic transition. Individuals make optimal decisions about fertility, education of their children and the type and intensity of the investments in their own education. These decisions are affected by different dimensions of mortality...

The objective of this paper is to estimate the potential pro-poor bias in the existing structure of protection in six countries in Sub-Saharan Africa (SSA) (i.e., whether it redistributes income from rich to poor households). We also explore the extent to which the barriers faced by SSA...

Long-run trends in Africa’s well-being are provided on the basis of a new index of human development, alternative to the UNDP’s HDI. A sustained improvement in African human development is found that falls, nonetheless, short of those experienced in other developing regions. Within Africa,...

In this paper we propose estimates of the marginal cost of public funds (MCF) in 38 African countries. We develop a simple general equilibrium mode inspired by the “1-2-3” model of Devarajan et al. (1994) that can handle taxes on the five major tax classes, takes account of the informal...

The first generation of genetically modified (GM) crop varieties sought to increase farmer profitability through cost reductions or higher yields. The next generation of GM food research is focusing also on breeding for attributes of interest to consumers, beginning with ‘golden rice’, which...

Can international migration promote better institutions at home by raising the demand for political accountability? In order to examine this question, we designed a behavioral measure of the population’s desire for better governance. A postcard was distributed to households with the pledge...

Initiatives to improve market access for the poorest countries have recently been announced by the European Union, Japan and the United States. This Paper assesses the impact on Sub-Saharan Africa (SSA) of these initiatives and others that might be taken. We find that fully unrestricted access...
