Despite Narendra Modi’s successful leadership as chief minister of Gujarat, some question his ability to achieve the same progress at the national level as India’s prime minister. This column analyses Modi’s political background and state- and national-level experience to assess his capacity to navigate India through a politically and economically important time towards its goal of becoming a prosperous economy. It finds that while Modi can lean on his Gujarati experience to some extent, in other aspects he will have to depart from his incremental approach to policymaking in favour of radical changes, particularly in the area of employment maximisation.

The past decade has seen rapid growth in an interdisciplinary body of research examining the legacy of war on social and political behaviour. This column presents a meta-analysis and synthesis of this research. Evidence from surveys and experiments from over 40 countries reveals a stylised fact: individual exposure to war-related violence tends to increase social cooperation, community participation, and pro-social behaviour. However, these changes are mainly directed towards people from the same community.

When it comes to measuring GDP, researchers tend to use the latest vintage of the Penn World Tables. However, competing series like the World Development Indicators (WDI) and changing methodologies between vintages mean this is not necessarily the best approach. This column assesses the relative performance of different GDP estimators using night-time lights as an unbiased predictor of the growth rates of unobserved true income. Newer versions of the Penn Tables are not necessarily improvements on their direct predecessors.  Newer versions of the WDI index, especially the 2011 vintage, appear generally better at measuring cross-country income differences.

The importance of investment in children’s pre-school years for their later life outcomes is increasingly recognised by policymakers. This column surveys the evidence on early childhood development policies in both developed and developing countries. Research suggests that effective education programmes can be implemented at scale even in low-income settings, but the quality of the service and adapting it to the local context are crucial. Sustaining the gains from intervention in the ‘early years’ is also likely to require continuing investment at later stages of childhood.

The development accounting literature tries to account for cross-country output per worker differences by taking stock of inputs per worker. The data employed are often measured without great precision, however, making comparisons difficult. This column presents a new, internationally comparable dataset of average hours worked per adult across the world income distribution. Adults in poor countries are found to work a lot more and with lower productivity than those in rich countries. The findings suggest that those from poorer countries are not only ‘consumption poor’, but also ‘leisure poor’.
