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...

This paper reviews various treatments of non-metric variables in Partial Least Squares (PLS) and Principal Component Analysis (PCA) algorithms. The performance of different treatments is compared in the extensive simulation study under several typical data generating processes and...

In this paper the Social Institutions and Gender Index (SIGI) is constructed with Principal Component Analysis (PCA) and Partial Least Squares (PLS). Using the SIGI, we test the effects of social institutions related to gender inequality on several development outcomes, such as female education,...

Using newly comprehensive data and tools from the Global Consumption and Income Project or CGIP, covering most of the world and five decades, we present a portrait of the changing global distribution of consumption and income and discuss its implications for our understanding of inequality,...

This paper explores the impacts of traditional agricultural insurance that offers protection against climatic shocks on small-scale tobacco farmers in Colombia. We analyze the impacts of access to the insurance on household financial outcomes after a period of severe climatic events that caused...

The 2007/2008 food price crisis and the following global economic recession has (temporarily) increased the number of people to suffer from hunger. While the impacts can be measured with precision only ex post, for policy makers it is critical to get a sense of likely impacts ex ante in order to...

Development aid from the West may lead to adverse growth effects in the global South due to the neglected cultural context in the development framework. There is evidence that development agendas are mainly premised upon western thought and belief systems. Therefore, I hypothesize that the...

Using data from 1988 to 2007, we examine to what extent bilateral aid flows of an individual donor to a country depend on aid flows from all other bilateral and multilateral donors to that country in that year. We thereby want to assess to what extent donor coordination, free-riding,...

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...
