While tissue culture (TC) technology for vegetative plant propagation is gradually gaining in importance in Africa, rigorous assessment of broader welfare effects for adopting smallholder farm households is lacking. Using survey data and accounting for selection bias in technology adoption, we...

Most micro-level studies on the impact of agricultural technologies build on cross-section data, which can lead to unreliable impact estimates. Here, we use panel data covering two time periods to estimate the impact of tissue culture (TC) banana technology in the Kenyan small farm sector. TC...

Germany's education system stands out among OECD countries for early tracking: students are tracked into different secondary school types at the age of ten in most German states. In this paper we estimate the effects on educational outcomes of a reform that delayed tracking by two years. While...

In the absence of reliable and exhaustive income data, Proxy Means Tests (PMTs) are frequently employed as a cost-effective way to identify income-poor beneficiaries of targeted anti-poverty programs. However, their usefulness depends on whether proxies accurately identify the income poor. Based...

A body of recent research is pointing to a growing inequality in many countries. The current debate focuses on high income countries. However, developing countries are an important element in understanding the full picture. First, evidence indicates that growing inequality can also be observed...

In this paper, we compare Principal Component Analysis (PCA) and Partial Least Squares (PLS) methods to generate weights for composite indices. In this context we also consider various treatments of non-metric variables when constructing such composite indices. Using simulation studies we find...
