Research from the United States shows that gaps in early cognitive and non-cognitive ability appear early in the life cycle. Little is known about this important question for developing countries. This paper provides new evidence of sharp differences in cognitive development by socioeconomic...

In low- and middle-income countries (LIMCs) measuring early childhood development (ECD) with standard tests in large scale surveys (i.e. evaluations of interventions) is difficult and expensive. Multi-dimensional screeners and single-domain tests ('short tests') are frequently used as...

This paper examines gaps in child development by socioeconomic status (SES) using a large nationally representative sample of children 0–59 months old in Bolivia and a rich set of child health and development outcomes including measures from dried blood samples. Child development is assessed...

We investigate the relationship between individual trust and individual economic performance. We find that individual income is hump-shaped in a measure of intensity of trust beliefs. Heterogeneity of trust beliefs in the population, coupled with the tendency of individuals to extrapolate...

This paper extends the analysis of liberal principles in social choice recently proposed by Mariotti and Veneziani (2009a) to infinitely-lived societies. First, a novel characterisation of the inegalitarian leximax social welfare relation is provided based on the Individual Benefit Principle,...

Climate change is imposing a large burden on the most vulnerable populations, particularly in the developing world. Establishing consistent causal relationships, however, is difficult because a multiplicity of climatic, economic and sociodemographic elements are combined to create the conditions...

The creation of non-contributory pension schemes is becoming increasingly common as countries struggle to reduce poverty. Drawing on data from Mexico's Adultos Mayores Program (Older Adults Program) --a cash transfer scheme aimed at rural adults over 70 years of age-- we evaluate the effects of...
